Trimming the door frame with a threshold. How to properly assemble a box for an interior door. Installation of door hinges

Making your own door frame

It often happens that the door frame is not included with the door, or it is included, but sold unassembled, or it is available, but does not fit your doorway - not all types of door frames are suitable for the openings for which they are intended . Or you are just confident in your abilities and want to save money by making a box with your own hands. And there is nothing impossible in this. But still, before you make a door frame, check the availability of the necessary tools and materials, which will be discussed below.

What is a door frame made of?

All types of door frames are based on four profile bars - two long ones, located vertically and constituting the side parts of the box, and two short transverse ones, which are respectively the upper and lower parts of the box.

Removing the dimensions of the future door frame

Bars for the box can be bought ready-made or made by yourself, it all depends on your desire, skills and available tools.

If you are making a box from scratch, you need to start by taking measurements. You can do this in two ways:

On the finished door.

Through the doorway.

If you are using a door to be installed as a basis, measure the sides of the door first, adding 5 cm to each. Then measure the top and bottom of the door, also adding 5 cm each. Calculate the results and you can start cutting.

Preparing for cutting and making parts

It is better to start with the bars intended for the side parts of the door frame. The prepared bars are placed on the floor, at the same level, so that the grooves are on top. On them it is necessary to mark the upper and lower borders of the door, taking into account the thickness of the threshold. Then, bars are applied for the upper and lower parts of the door, on which marks are also made for the future cutting line.

After that, you can cut the blanks under the box. First, in order to avoid errors, it is desirable to cut off the blanks with some margin. After that, they should be tried on, and only then make a more accurate fit of the parts.

Production and docking of the door frame

There are two ways to join the side and transverse parts of the box:

at an angle of 90 degrees;
at an angle of 45 degrees.

The second method is more difficult, it requires certain skills and extreme accuracy. And for those less experienced in such matters, it is better to use the first method, and cut the side parts at an angle of 90 degrees.

Side preparation

Then, on one of the side parts, which will be located on the side of the loops, you need to mark the places where the loops will be. Do this by attaching this part to the side surface of the door. The depth of the groove is made equal to the thickness of the hinge leaf. The recesses for the hinges are cut out very carefully so as not to damage the door leaf. With your own hands, this is easy to do with a chisel and a hammer, while experts usually use an electric cutter.

Next, you need to put the loops into the recesses prepared for them in this way, and using a drill, make recesses for self-tapping screws on the side surface. Moreover, the diameter of the recesses should be less than the diameter of the screws that will be located here. Then, using self-tapping screws, the hinges are attached to the door leaf.

A latch lock is installed on the other side surface of the door.

Do-it-yourself box assembly

It is most convenient to assemble the details of the door frame into a single whole with your own hands on the floor covered with cardboard or paper. The actual assembly of the box consists in connecting the prepared parts with self-tapping screws. But first, you need to very carefully combine one of the corners of the box, and drill a couple of holes from the side of the transverse bar into the end of the longitudinal part with a drill or screwdriver. This is done to prevent damage to the door leaf with self-tapping screws in the future. Further, self-tapping screws are screwed into the prepared holes. Thus, two self-tapping screws are screwed into all corners of the box (at a right angle).

Do-it-yourself door frame installation

After the manufacture and assembly of the box is completed, you can begin its installation in the doorway, for which you will first need to “try on” the box made. Check the verticality of the box with a plumb line, and the squareness of all corners. It is possible that you will first need to fit the box, which consists in eliminating gaps with wedges or foam.

After that, the box is attached to the slopes with dowels. Don't forget to make sure there are no "adjusting" wedges or slats visible anywhere. Only after this can the manufacturing process of the door frame be considered complete. Then it remains only to hang the door leaf on the hinges and attach the trim.

In general, assembling a door frame with your own hands is not as simple as it might seem. Still, this requires some experience. But if you are still determined, first you should study the theory of this process well, and study useful photo and video materials on it.

How to make a door frame: DIY process

The door frame is basically a frame that contains bars and folds. Strengthen the box with special bolts or use steel lining.

The door frame can be assembled with your own hands using wooden blocks and fasteners.

Use a plumb bob and level to prevent unevenness when setting up the box. In the case of stone walls, the box is attached to wooden corks using nails. If the walls include slabs, the structures will only be supported by brackets.

Self-made box

In order to understand how to make a door frame with your own hands, you need to familiarize yourself with some points of the work itself.

To begin with, dimensions are taken. There are 2 ways to retrieve data:

along the doorway;
on the installed door.

For example, the calculation of data on the current door. First, measure the sides, add 5 cm on all sides of the door. Next, measure the threshold and the upper part of the system, leaving room for an allowance. Then they calculate the footage and start sawing.

Next, the bars are folded on the floor, they will be needed when setting up the side box. They should lie on the level, grooves on top. Mark the upper and lower boundaries of the future door, while adding the thickness of the threshold. From the bars that are applied to the threshold and the crossbar, certain notches are made so that the sawing line is visible.

Scheme for taking measurements of the doorway.

Then the prepared materials are sawn for collection. After cutting the blanks, it is necessary to adjust them to the appropriate size. In one of the blanks, a slot is made for future loops using a chisel and a hammer. Before you start doing, you need to know the necessary side of opening the structure.

To continue self-assembly, it is necessary to use self-tapping screws and nails for the strength of the future structure. Next, hinges are hung and the doorway is strengthened. Even out the gaps.

The necessary tools to help assemble the door are:

Use a set of screwdrivers of different configurations, use pliers, crowbar, small nail pullers.

A hammer drill is required to punch a hole in concrete. A miter saw can prepare materials for the door. Quite a lot does and electric milling cutter. With the help of it, holes of the necessary locks and hinges are made in a short period of time. If there is a large set of cutters, then even better. If it is necessary to make a door frame with special quality, a woodworking machine will also be needed.

Some Features

Door frame device.

The process itself looks something like this. First, a smooth board 5 cm thick (maybe several) is prepared, 4 identical segments are made from it. 2 of them are equal to the length, 2, respectively, to the width of the opening.

At the same time, the segments have processing of only 3 sides - they must be made very smooth, the 4th is placed near the wall. Focusing on the width of the board, make a cut into which the door will be inserted.

An incision is made only on the side where it opens. If a double door is planned, cuts are made on all sides. It is easier to make cuts on the machine, where it is possible to raise the table and adjust the required length. The existing material is cut to the required length, all ends are machined.

When all the necessary blanks have been prepared, they begin to process the transverse segments. Longitudinal compartments of standard doors are 193 cm, transverse - 90 cm. The cut at the end of the door frame should be 1.5 cm deep and 5 cm wide.

First, you need to attach all the strapping located on the top and side, and only then begin to install the box itself in the doorway. In this case, there must be a space between the door and the wall of 2 cm. In the future, it is used as thermal insulation.

One of the important elements in fixing the door is washed down. There are 2 options for sawing boxes: 45° and 90°.

The scheme washed down the door frame.

I washed down the boxes at 45 ° as follows:

boards are taken;
the necessary marks are made on the inside, the unnecessary is removed;
sawing angle inside should correspond to 135°, and outside 45°, along the length of the vertical boxes should be standard and the same.

The same is done with horizontal small bars. It differs only in that it is necessary to saw off from all sides. The most important thing is not to make mistakes in sizes.

To assemble the box at 90 °, place the finished parts of the future door on a flat surface. The corners are neatly connected with self-tapping screws, screwing 2 self-tapping screws into all corners (at right angles).

To keep the door frame in the desired position, several methods can be used:

Strengthening the door frame with small rails. Reiki must be fixed perpendicular to the racks with small nails (screws).

Adding wide and hard corners that are designed for fastening. Install all corners, carefully checking the perpendicularity and verticality.

A box is inserted into the doorway and correctly centered. At the end of all work, be sure to check for cracks, distortions and other irregularities. If necessary, use a seal.

In order for the box to be fixed qualitatively in those places where there is contact with the wall, a sealant is placed.

At the end of all additional operations, the perpendicularity of the elements on the side is checked.

Of course, if you use all the specialized tools and assistants who can supply parts if necessary, making a door on your own will be quite simple. So choose the option that suits you. Good luck!

We assemble and install the door frame with our own hands

In most cases, the door frame comes already assembled with the door. But you can often meet a product from different components, especially if you need to assemble a structure for a non-standard doorway. The very process of assembling and installing such a device is quite complicated, especially if there is at least minimal knowledge and skills in carpentry.

But nothing is impossible for a person, and therefore he is able to assemble a door frame with his own hands. Naturally, this will require a lot of effort to conduct the correct measurements and process the material. But if you follow a consistent algorithm for performing work, everything can be done in a short time, saving both time and money.

What is a door frame for?

Under the door frame means a special element. used in the design of the doorway, which essentially acts as a supporting structure on which the canvas is hung. In its form, it follows the contour of the doorway, framing its inner part. It is on it that hinges are hung, on which the door leaf will open or close. Without a door frame, it is simply not possible to install the door itself.

The structure of the box includes several basic elements: side frames, top cross and nut. If necessary, the kit can be supplemented with extras. But in order to fully understand the sequence of doing all the work with your own hands, you need to consider all the stages from choosing the right material to installing the finished box in the doorway. But let's talk about everything in order.

Material for the manufacture of the door frame

If the homeowner decided to independently assemble and install the door frame, then first you need to choose quality material. In this case, the choice should be based on the parameters of the weight and dimensions of the canvas, since all the load from it will go to the door frame. At the same time, the following materials are considered popular for assembling a door frame:

wood;
metal corners;
finished sidewalls from MDF.

The most popular is wooden box. which you can easily do yourself. In this case, the selection of suitable bars usually does not create any special problems. There are already prepared blanks on the construction market, from which you can quickly construct a frame for a doorway with your own hands. All that is needed is to fit the required dimensions and connect the constituent elements into a single structure.

Wood is a durable, practical and, most importantly, environmentally friendly material. It is fairly easy to process. In most cases, do-it-yourself pine is used to assemble a door frame, but due to its comparative softness, it does not have high strength. Therefore, for the front door, it is better to use harder types of wood, such as oak.

If we consider MDF as a material for a door frame, its use is advisable only in openings between rooms with a low level of humidity. Metal structures are leading in their strength, but to work with them you will need a welding machine, and outwardly they do not look very aesthetically pleasing.

DIY tool kit

In order to obtain a quality result, it is important prepare the instrument according to the following list:

a hacksaw for wood and a miter box for cutting parts at the right angle;
electric screwdriver or a set of screwdrivers;
chisel for chamfering under door canopies;
drill with rebound function for attaching the box to the wall;
construction hammer, water level and a simple pencil;
mounting foam bottle, nails, wedges and fasteners.

Preparatory stage

On the door leaf with an electric cutter or chisel, chamfers are selected for the installation of canopies. Important keep the minimum distance from the extreme top and bottom of the canvas to the loop, which should be 200 mm.

At the next stage, slopes are cut strictly at an angle of 45 degrees. Then the prepared part is applied to the door leaf, and the attachment points of the canopies on the jamb are outlined. Again, with the help of a chisel or its electric substitute, recesses are made according to the size of the loops.

In the resulting recesses are invested corresponding halves of the loops. which are fastened with self-tapping screws using a screwdriver. But holes are pre-made to prevent cracking of the wood. It is important that the diameter of the drill is slightly less than the thickness of the self-tapping screw.

Do-it-yourself box assembly and installation

The next stage of independent work is the assembly of the door frame, which provides certain sequence of actions .

The ends of the upper crossbar of the door frame, in accordance with the dimensions of the leaf, are cut at an angle of 45 degrees.

The slope structure should be 5 mm along the inner perimeter, larger than the main canvas.

To fasten the elements of the door frame, holes are made at the corners of the structure.

The length of the slopes is also shortened in accordance with the dimensions of the door leaf, taking into account the necessary clearances. According to technology, the gap between the lower edge of the canvas and the floor surface should be 10-15 mm.

The blanks are folded in the shape of the letter "P" on a flat, clean floor and are interconnected using self-tapping screws through holes made in advance.

In the grooves for the installation of hinge mechanisms, through holes are made for attaching the door frame to the wall. With the help of a dowel, the upper part of the structure is fixed in the doorway.

The structure of the box is aligned with the water level and fixed at the bottom with dowels.

After fixing, wedges are pushed into the resulting gap between the box and the wall, and the screws are finally tightened.

If we consider how to install a door frame in a wooden building, then there are some nuances. First of all, it is necessary to provide removable casing bars from the side of the handle, thanks to which you can increase the width of the structure. This is primarily due to the shrinkage of wood after the construction of the house for 6 years.

Installing a lock mechanism with a latch

Fastening the door handle is an important stage, since it will depend on it. ease of use of the door for its intended purpose.

The door is settled in a horizontal position and at a distance of 100-120 cm from the bottom on the side opposite from the canopies, a hole for the latch is drilled with a crown of the appropriate diameter.

The latch is inserted into the recess and circled around the perimeter with a marker. Further. a cutter or chisel makes a recess under the front bar.

The valve body is inserted into the recess in such a way that it is placed in the same plane with the level of the end of the door leaf.

On the door leaf under the handles, marks are made along which holes are drilled.

The latch is placed in its place and secured from the end with self-tapping screws.

In conclusion, also with the help of self-tapping screws handles are fixed and decorative special overlays. Their fastening is carried out with special hexagons.

Hanging door leaf

At the next stage the canvas is hung on hinges. attached to the door frame.

When hanging the door, use self-tapping screws to fasten the hinges. At the same time, the canopies will hide the attachment points of the box in the doorway.

After the canvas is installed in its place, it should not spontaneously open or close.

Wedges are driven into the upper part of the box for reliable fixation.

At the next stage, a striker plate is attached under the latch. To do this, the door is covered and a place is marked at the level of the bolt. In the door frame, holes are drilled according to the diameter of the latch.

At the next stage, the second half of the box is fixed. To do this, the door closes and the same gap is set along the entire length of the canvas.

At the height of the latch, a wooden wedge is inserted into the gap between the box and the opening, which is attached to the wall with a self-tapping screw through the hole for the locking mechanism.

In conclusion, the box is securely fixed with wooden wedges. and the locking plate for the latch is installed in its place, thereby hiding the place where the structure is attached to the wall.

Filling mounting gaps with foam

In order to prevent the penetration of drafts into the room through the gaps between the box and the wall, as well as to more reliably fix the door structure, all gaps filled with mounting foam .

Use masking tape to prevent foam from entering the faceplates.

The gap between the box and the opening is wetted with water and filled with construction foam.

After the final hardening of the foamed sealant, it is cut off with a knife, and the adhesive tape is removed together with the remaining foam.

Installation of decorative platbands

The final stage of the installation of the door frame is its decorative trim with cash.

Docking of platbands is carried out at an angle of 45 degrees. For this purpose, a hacksaw and a miter box are used.

Before fixing the platbands, a sealant is applied to the surface of the jambs.

The prepared parts of the casing are fastened with small nails with cut heads.

With a minimum set of tools, consumables, and the main desire, everyone will be able to assemble and install the door frame with their own hands. In this case, all work will take just a few hours. The main thing is to control the installation of the box in accordance with the water level and the plumb line.

Popular ways washed down door frames. When buying a new door, you should think about how you will make the door frame washed down. Naturally, you can invite specialists for this, but if you want the most, you can always do the installation yourself. Let's look at the specifics of the work in more detail. Installation is a crucial stage, since the operation of the door unit as a whole will depend on the correct installation.

Installation requires special attention, since the operational properties of any door depend on this. Let's look at different ways to install the box, taking into account the configuration of the door unit and the material used for production.

In order for the installation of the door block to be successful, everything should be carefully thought out, measured, studied and selected in advance. You should inspect the opening that you plan to close with a facade. In older rooms, openings and walls are not ideal, and this is often found even in new buildings. The measurements of the opening must be careful and correct on each side.

If you will not make a custom-made door with special dimensions, you should choose a ready-made option that will meet certain standards. When taking measurements, it will be possible to understand what to do with the doorway, which should not differ much in size from a regular canvas. For example, if the width of the portal is 0.9 meters, then the door should be taken 0.8 meters in size. The remaining cm will remain for the door frame and the technological gap that is needed.

When you determine the size of the product, you should choose a complete set of doors. On the rack in construction markets, you can find three types of kit at once:

The very same choice of product will depend on the buyer. The most difficult and lengthy installation method is the purchase of the first version of the doors, since you will need to buy and assemble all the elements of the block yourself. For this reason, it is worth dwelling on this option in detail. Study the instructions below, and then you will be able to install the door without helpers.

Box Settings: A to Z

It can be assumed that the walls of the doorway are already prepared in advance for installation work, the doors are selected according to the size of the opening. For clarity of the whole process, a separate canvas is shown for the door frame. Installation is carried out in several stages, first you need to prepare all the tools, as well as cut off the extra length t of the box slats.

Where to begin

So, you should prepare a place in order to decompose all the elements. For this, flat floors that are covered with oilcloth or cardboard are ideal.

For installation you will need:

Listed here are all the tools for washing down the door frame at 45 and 90 degrees. Now you should consider step by step how the door will be installed.

Preparing the elements

First you need to unpack the door leaf, as well as the elements of the door frame (if they are provided in the basic configuration).
Inspect the product you bought and make sure that everything is clear in terms of configuration and without marriage. After installation, it will not be possible to return the door, even if it is defective.
Move the door leaf aside, you will need it a little later.
Lay out a beam for the door frame on the floor surface, and if the parts for the frame are purchased separately, you should pre-adjust them to the size of the canvas and the opening.

With this, you can begin the process of assembling the box. There are several ways to assemble the horizontal and vertical racks of the door frame, which we will discuss below.

Assembly types

Assembly in grooves

This method involves connecting elements with a slight overlap. A groove should be made in the vertical bar, which will make it possible to connect the vertical bar with the horizontal one under the front side. For most factory models, this assembly option is provided. With your own hands, you can make a similar groove if you plan to make racks from building timber, and not from MDF blanks.

First you need to take measurements so that you can file the parts to the required length. Measure the doorway in several places, and then take the smaller result as a basis, and do not forget to leave a gap for the mounting foam. You should also know the size of the door leaf, for this, the gaps should be added to the free movement of the door in the box. On each side, from 0.3 to 0.5 cm will be enough. The door leaf with a width of 0.8 meters and a height of 2 meters should be taken as a basis.

The door frame must comply with the following data:

For doors with a threshold - 0.806 * 2.006 meters.
Without a nut, taking into account the large gaps for opening the canvas - 0.806 * 2.010 meters.

As a rule, doors to the toilet and bathroom are installed with a threshold. For other openings, the threshold is not required so that there are no obstacles.

This completes the assembly of the box.

Assembly at a 45 degree angle

The second way - this washed down the door frame at 45 degrees. This method has slight differences in the sawing of rack elements.

Measurements should be carried out in the same way as in the variant of assembling the box into the groove described above. The only difference will be the length of the horizontal bar. It should be full width, i.e. 0.806 meters, since the edges will be filed at 45 degrees.
After the beam is sawn in the right direction, you should take the cuts at the required angle. To do this, take a miter box, which will play the role of an excellent template, and if there is no tool, then you should make a drink by eye.
Connect all the elements with self-tapping screws, drive them inward at an angle of 45 degrees.
Once again, everything should be checked so that the dimensions match.

Ready! The method is simple, and at the end the door frame looks very beautiful.

Assembly at a 90 degree angle

This method is by far the easiest. It is available for DIY assembly. For self-assembly, it is better suited than the first two options, since it does not require special skills and special tools.

All you have to do is choose any way you like to wash down the door frame. Further, the installation process can have two development paths:

Installations in the opening of only one box, and after hanging the canvas.
Complete installation of the whole set.

The second option is usually used, since it is difficult to hang the canvas after the installation process in the opening and only experienced craftsmen can do it.

Installation of fittings and door leaf in the box

Hinges should be screwed to the assembled frame, and they can be completely different, but despite this, the installation process is not much different:

Make markings on the top rack, while taking into account the opening side of the door leaf. 0.2 meters should be retreated from the upper edge and attach the loop bar to the bar. Circle the outline with a pencil, and along it you will make a notch to secure the loops. Similar markings should be done for the bottom loop.
Using a chisel, chisel and hammer, remove excess wood to get the groove you need.
Try on the loop, if everything is perfect, you can attach it to the seat.
Similar manipulations should be done with the canvas.
After the installation of the hinges is completed, the canvas should be laid inside the door frame.
Check for the necessary clearances, place cardboard so that the canvas does not move when the block is installed in it.

And now it's time for the most crucial moment - the installation of the product in the doorway.

Installing the box in the opening

Still, you can't do without the help of a friend. The installation stage in the box opening is the most difficult, so you need to be careful, patient and attentive. The block with the door is very heavy, and the work should be carried out as accurately as possible.

This completes the installation of the unit, and you can do all the work yourself if you use the described instructions

How much can you save on installing a door yourself

Not every manufacturer offers to install doors or windows for free, and the price sometimes reaches unprecedented levels. On average, the cost of specialist services varies depending on the price of the goods and the complexity of the work. Sometimes it reaches 50% of the block cost. The cheapest door itself in the whole set will cost no less than 7,000 rubles, and installation will be about 3,500 rubles. This is the average value for the service of masters, and the price may be higher. For this reason, the savings during installation are significant, especially if several doors are to be installed at once.

The interior door serves to divide the space in the room, and also provides sound insulation in a private house or apartment. In addition, the door leaf is an important interior detail, so it must match the design style. Since installation work is quite expensive, the question arises of how to properly install interior doors with your own hands. The answer is in the detailed step-by-step instructions on this page.

Dimensions and equipment

According to the method of opening the doors are folding, sliding and hinged. The latter are the most popular, since they are structurally the simplest and fairly easy to install. They are presented in a large number of modifications. According to the method of opening, the following are distinguished:

double-sided and single-sided;
left and right sided.

Step 3: Installing the box and hanging the canvas

The box must be installed in a pre-prepared opening. The hinge post must be leveled first with a plumb or level. It is necessary to check it from all sides. Then the upper crossbar and the rack must be spread with wedges. The rack will only be exposed when it is in a vertical position.
Next, wedged the second rack. Be sure to check the horizontal part of the box.

The old way - the side racks must be drilled through. To do this, holes for dowels are initially made in the wall. The box must be attached to the wall with self-tapping screws at least 150 mm long.

Old way fasteners

In order to fix the box in the opening in a hidden way, you can use metal plates, which are usually used to install drywall structures. Most often, such plates are used together with anchors. In this case, it is worth choosing the number of fasteners in accordance with the expected load.

This is what the mount looks like

The use of such plates is a non-standard method and is possible only in the absence of a fine finish. It is recommended to gouge a section of the wall in order to subsequently putty the fasteners.

It remains to hang the door on the frame. After that, you need to carry out the final adjustment of the box. The lock post must then be fitted under the door so that it does not protrude beyond the wall. It is worth remembering that in order to preserve the integrity of the box and canvas, you must first drill several holes for the screws.

Step 4: Foaming

After fixing the canvas, you need to foam the gaps between the box and the edges of the opening. The foam should be fed carefully, in layers, while the feed is from above so that it does not come out. Then the door will have to be closed and not touched for a certain time so that the foam dries. Estimated drying time is 1 day.

If the composition accidentally gets on the canvas, immediately remove it with a clean, dry cloth, dried fragments are cleaned with effective ones.

Step 5: Installing the lock and handles in the door leaf

The most popular today are handles with a built-in lock. The order of work is as follows:

Make a mark one meter from the floor. The handle mechanism must be applied so that the mark is visible in the hole from above.
Drill holes in the canvas from the end. After that, the edges of the holes should be cut with a chisel to align the hole.
Insert the mechanism into the hole. In this case, the lock must be aligned, and then fixed with self-tapping screws. The bar on the lock should be outlined with a pencil to cut the veneer, then the mechanism should be removed. According to the outlined contour, you need to select a site to determine the thickness of the locking bar. This is done using a chisel.
Drill holes for the latch and handles. It is necessary to attach the lock to the canvas from different sides, align it and mark it. Holes must be made on both sides and they must not be through.
Remove the formed chips and install the handles.

Step 6: Installing the trim strips

An extension is a plank about 2 meters long, 250 mm wide, and no more than 3 cm thick. The plank should be used during the installation of interior doors if the wall is thicker than the door frame.

The bar for the box is made in a standard width - approximately 70 mm. It can be expanded according to the thickness of the opening with an extension. This will allow you to more clearly combine the box and walls. On the bar there is a groove for the strap. First you need to measure the distance to the edge of the wall, starting from the depth of the groove.

The add-on can be installed in different ways:

into the groove in the box;
with cutting a groove in the absence of finished;
attaching the extension from the inside of the timber in the absence of a groove, the box is installed at the same time together with the extension;
fastening dobor in the form of "P";
if the extension is not too wide and there is no groove in the box, the bar should be drilled and screwed to the box.

The plank is sawn into several parts with a circular saw to get several extensions of the required dimensions. You need to prepare one short bar and two vertical ones. Check out our simple step by step guide to .

Step 7: Trim fasteners

During the installation of platbands, the box must be located at the same level as the opening on the front side. To connect the platbands, you must first attach a vertical bar to the box and put a mark 0.5 cm higher, stepping back from the crossbar of the box. This mark will act as the cut edge. In the same way, you need to mark the cut on the other side.

The final stage of repair work in residential or commercial premises is the installation of interior doors. High-quality assembly and installation of the box in the appropriate opening is the key to reliable locking of the canvas, the correct operation of the main and auxiliary mechanisms.

The door frame is mounted in a wall opening, therefore it is a key part of the finished structure, to which the leaf is attached to the hinges. Let's figure out how to assemble a door frame with your own hands without involving third-party specialists, following a simple step-by-step instruction.

Choice of box sizes

Boxes for interior doors are made of reliable and practical materials - MDF, chipboard and wooden beams. The design of the box consists of several functional elements, so for its installation it is necessary to know the dimensions of all components.

The dimensions of the door frame of the interior door are determined by the thickness of the walls and the dimensions of the door leaf:

For brick walls 7.5 cm thick - a box 10.9 cm thick;
For walls made of wooden paving stones up to 10 cm thick - a box 12 cm thick.

The thickness of the door frame from foreign manufacturers may differ from the indicated dimensions, amounting to:

8 cm;
10 cm;
12.5 cm;
14.5 cm;
18.5 cm;
20.5 cm.

The correct ratio of the parameters of the thickness of the box and the wall opening eliminates the occurrence of violations in the future. With a wide wall and a narrow box, the finished structure must be expanded with wooden planks or boards installed in special grooves.

As standard, the frame for the opening is equipped with a special cutout, the depth of which is equal to ¼ of the thickness of the door leaf.

Modern models of interior doors can have different dimensions, but the standard size is 80 cm. The width of the door frame is presented in two ranges:

Height - 2 meters, width - from 60 to 80 cm;
Height - 1.9 meters, width - from 55 to 90 cm.

Finished products are ordinary and profiled, and the width of standard elements can be from 1.5 to 4 cm.

Tools and materials for work

Installation of the door frame is carried out using the basic tools and necessary materials.

For work you will need:

Bars and wedges wooden.
Electric cutter.
Hacksaw equipped with a miter box.
Screwdriver.
Drill.
Self-tapping screws, nails with small hats.
Construction level.
Mounting foam.
Construction pencil.
Knife with a thin sharp blade.

For installation work, the room must be dry and well ventilated.

The box is a frame-type structure, consisting of vertical guides - a loop and a feigned jamb. The hinge beam takes on the load of the installed door.

Preliminary installation work

Do-it-yourself installation of interior doors is carried out after finishing work on leveling wall surfaces, installing floor cladding and other finishing work.

Finished slopes should be checked vertically in several places. If a difference of up to 5 cm is detected, the slopes are leveled. Similarly, horizontal jumpers are checked. A technological gap of 15 mm should be observed between the floor surface and the door.

Proper assembly of the door frame determines the phased work:

Using a cutter, small recesses are made for hinged joints in the door leaf. The distance from the edge of the canvas to the edge of the loops (top and bottom) must be at least 18 cm.
The slopes are sawn at an angle equal to 45 degrees. The surfaces are carefully cleaned and trimmed, applied to the canvas and marks are made where the loops on the jamb will be placed. Using a cutter, recesses are made for the door hinges.
Finished hinges are inserted into the existing recesses in the canvas, holes are made for self-tapping connections with a drill. In this case, it is recommended to choose a drill whose diameter is equal to the diameter of the self-tapping screws. At the end, the hinges are fixed to the door leaf.

Installing the handle and lock

The next stage of work is fixing the handle and lock on the door, which is performed after installing the hinges.

The canvas is turned over in a horizontal direction and at a distance of 85 to 118 cm on the side opposite the hinges, a recess of the required diameter is drilled to install a lock with a snap mechanism.
The lock is inserted into the recess, edging is done with a pencil. Using a cutter, another recess is made for attaching the front plate with a valve.
A valve is inserted into the canvas, while its body should be located at the level of the end of the door.
Next, marks are made on the door with a pencil under the recesses for the handles, which are drilled with a drill.
The lock latch is mounted in a recess from the end part and fixed with self-tapping screws.

Finally, handles are installed on self-tapping screws and decorative overlays using a simple hex wrench.

Complete assembly and installation of the box in the wall opening

At the final stage, the door frame is completely assembled and installed in the corresponding wall opening.

In the transverse box with a hacksaw, the ends are cut at a 45 degree angle. This will ensure a smooth and reliable docking of all elements. In this case, the width of the opening should exceed the dimensions of the door leaf by 6 mm.
The drill makes holes in the cuts of the angular type for the correct connection of the box. Many models of doors, which are equipped with platbands and slopes, are equipped with special cuts and fasteners. In this case, there is no need to drill additional holes.
Further, the slopes are carefully shortened in accordance with the dimensions of the finished door, observing the technological gaps between the floor and the lower part of the door of 15 mm.
All elements of the box are folded into a U-shaped structure on a flat surface and are securely connected with self-tapping screws.
In the grooves that are intended for mounting the hinge, a through hole is made to fix the assembled box to the wall surface. The box is fixed at the top of the opening with a long self-tapping screw.
The vertical position of the rack, to which the door hinges are fixed, is checked by the building level. Correction is carried out using wedges driven into the groove between the post and the slope.
A similar procedure is carried out with the second rack.
The horizontal location of the structure lintel should be parallel to the floor surface. Correction is performed with wedges.
After a complete check of the position of the box, the structure is securely fixed from below with self-tapping screws.
Next, it is recommended to hang the door to check the correctness of the work.

Step-by-step instructions for assembling and installing the box involves another important step - hanging the canvas.

Hanging the canvas is carried out using self-tapping screws, while the loops reliably hide the fixing elements. When properly hung, there should be no arbitrary opening / closing of the door.

After securely fixing the box and installing the canvas, the wooden wedges are removed from the technological gaps, and the existing gaps are filled with mounting foam, having previously covered all the installed fittings with masking tape.

Even a novice master, with the necessary tools, can perform his first installation of a door, whether it is an apartment, a house or a bathhouse. The main thing is to observe all stages of work and carefully check the correct fixation of all structural elements.

When buying doors in a store, we obviously get a door block that is not fully prepared for installation, but a scaled-up likeness of a children's designer for "skillful hands". It is quite understandable why hinges are not hung and locks are not embedded, because it is not known which side the door will open. Manufacturers do not assemble boxes, because they do not know exactly the dimensions and features of the opening to be equipped. Therefore, the owners have to hire craftsmen or independently build this important part of the door block. And for this, you need to clearly know how it is possible and necessary to cut a bar, how to assemble a door frame for the long-term service of an interior or entrance structure.

What is the root "hitch"?

The complexity of a number of operations for the assembly of the base frame for hanging the door lies in the specifics of the production of cuts and in the connection of the components. Simple in the eyes of an inexperienced layman, the work is hampered by the presence of a feigned recess on the profiled jambs and crossbars of the future box.

Two schemes for building a box

You can dock them by doing the cuts:

at an angle of 45º, for which you need a good miter box with an award, but it is much better if you can saw off the excess beautifully with a miter saw;
at an angle of 90º, the implementation of which will require not only a fine-toothed saw and the accuracy of the performer, but also knowledge of the technological subtleties of essentially not too complicated work.

To perform a strong docking of components, galvanized self-tapping screws or “nailless” spiked joints are used. Spikes can be formed at both of the above angles. However, they are milled mainly perpendicular to the full thickness of the box beam, which must be taken into account when calculating and marking the length and width of the door frame-box.

It doesn't matter if the spikes of the transverse bars of the box will fit into the grooves of the horizontal ones or vice versa. If only the connections were strong and unshakable, for which they are sometimes reinforced with additional nailing with zinc coating.

The shape and dimensions of the structure

The geometric parameters of the base box under construction determine two conditions:

the width and length of the door leaf itself, for the coverage and support of which this frame is intended;
purpose and category of the equipped premises.

Therefore, even before the starting stage of work, it is necessary to clearly define where and how to install the door frame the owner of the door and opening in his personal property wants to install.

Depending on the purpose of the premises, the requirements for ventilation or insulation, which the door must provide, change. The entrance door to the bathhouse and the door to the steam room should not let the cold in and release the fertile warm air out. The washing department, on the other hand, needs additional ventilation so that the excess of vaporization is spontaneously unloaded and the building materials do not rot. Additional ventilation is required in the boiler room, especially if gas equipment is installed there. What can be done:

If it is necessary to provide a barrier against heat leakage, the construction of the door frame will require four bars, which, after connection, will turn into a closed rectangular frame. The door frame will consist of a feigned and hinged vertical bar, a lintel - an upper crossbar and a threshold connecting two vertical elements in the zone of their junction with the floor surface. A 3 mm technological gap must be maintained between the box beam and the door leaf along the entire perimeter for the free movement of the door.
If it is required to ensure a natural outflow of steam and polluted air, the box is assembled only from three parts, since instead of a threshold that prevents aerodynamic processes, a gap of 15.0 - 20.0 mm must be made. In such cases, the door base resembles the letter P. The 3 mm gap laid down by the technology passes only along the vertical pillars and the lintel.

Between the threshold and the newly laid floor covering, a gap of 2-3 mm should be left in case of thermal movements.

A closed box, of course, is higher than an open analog, as it is increased due to the thickness of the nut. This nuance must be taken into account in the calculations so that the door leaf does not have to be "shortened", which is especially undesirable if it is covered with veneer.

Important. If you do have to cut on a veneered surface, start on the finished side and work your way to the unfinished side. So the veneer will suffer the least, the chips will be insignificant.

The sequence of the simplest assembly scheme

There are not too many people who want to mill or painstakingly choose spikes with grooves without experience, and not everyone stocked up on equipment for perfect sawing diagonally. Therefore, most home craftsmen stop at the simplest scheme with the joining of elements at a right angle.

Now let's find out how to properly assemble the door frame. It is more convenient to work by laying out all the components at the same level horizontally. Most often this happens on a floor covered with cardboard or other soft material, less often on two tables moved together, four stools can be adjusted.

When buying a timber separately from the canvas, please note that the base for fixing the door in the opening should not be narrower than the canvas, and wider than the wall.

Work order:

On the site equipped for work, we lay out the box beam with the front side up, that is, outward with the porches. If the beam is wider than the canvas, we bring the plane of the door to the same level with the future box, placing paperback books under the canvas. According to any of the selected schemes, first three standard elements are involved in the work: a feigned and looped jamb and an upper crossbar.
The upper crossbar of the door frame, installed in a brick or foam concrete opening, is recommended to be made wider than the box to increase the bearing capacity. Usually it is 0.5 cm narrower than the opening. To search for attachment points for vertical bars to it, first find the center of the lintel, then set aside equal distances in both directions.
To form an equal gap around the entire perimeter between the canvas and the boxed beam, cardboard or old linoleum cut into pieces is laid.
Having marked the gaps, we outline the cutting points without scratching the surface. It is better to press lightly with your fingernail. A pencil, especially a poorly sharpened one, is not recommended for marking by experienced craftsmen. It will not provide accuracy.
We saw off the crossbar according to the chosen scheme.
It is desirable to mark with an awl or a sharp scalpel a part of the feigned profile, which must be removed so that a plane forms at the junction. Then we “cut off” the marked area neatly with a chisel or saw it off. This is one of the most significant stages in the assembly of the box, which does not tolerate inattention and mistakes. A slight shortage in the length of the box bars will still be covered by the platband, and poorly cut with a chisel or sawn off ledges of the vestibule will be visible. Have you decided to drink? Take a hacksaw and cut so as not to accidentally tear off the veneer from the underlying plane. For insurance, it is better to cover it with cardboard. After we have done washed down to the depth of the protrusion, we clean off the excess with a chisel.
We lay out the sawn-down bars back around the canvas with cardboard in the gap. With maximum accuracy, we note the location of the loops. The standard is an indentation for installing hinges of 20 cm from the top and bottom of the web. Without forgetting about the upper gap, we set aside a point on the hinge bar at a distance of 20.03 cm from the intersection of the lintel and the jamb.
We put on two screws a loop map to the hinge bar and mark with a scalpel or awl the shape of the nest and the points of the holes for the screws. Slowly, scrupulously remove the veneer or array to a depth equal to the thickness of the card.
We put the flags of the loops in the nests and fix them there with self-tapping screws. The lock striker on the box is installed only after the box is fixed in the opening and the canvas is hung, as there may be discrepancies.
We return the loop bar to its place. We carefully verify the perpendicularity of the elements to each other. We fasten the crossbar and racks, distributing two self-tapping screws per connection.

The threshold is made in the same way as the lintel.

Features of assembling a box for wooden baths

Wood is an excellent building material, which differs from others in the ability to settle after construction, which is not too pleasing to the owners. Openings in baths and houses made of logs or timber should not be equipped at all in the next couple of years after the construction of the crowns. Moreover, it is necessary to find out how to properly install the door frame in a timber or log opening.

There are 2 options here:

If the width of the opening formed during the construction process corresponds to the design solution, a groove is cut in the end right in the middle and then a beam is hammered into it. It is to this beam that the box can be nailed, it is impossible directly to the walls, because even after shrinkage they continue to “settle” a little.
If the opening is not formed, you need to cut a hole for the passage with a width less than the design one by two thicknesses of a kind of ridge. Box timber in such cases is made with a groove.

In both versions, the elements of the box at the same time serve as a connector for the crowns. A gap is always left above the opening to protect it from deformation during the shrinkage period.

Which of the methods of collecting the box to use is up to the owner to decide. A lot depends on the specifics of operation and on the properties of the building material. With the most significant points and subtleties that you should not forget, we tried to acquaint.
