Final stage repair work in residential or commercial premises - 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, right job 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 see how to assemble door frame do-it-yourself without the involvement of third-party specialists, following a simple step-by-step instruction.
Choice of box sizes
Frames 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.
door frame thickness 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 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 various dimensions, but standard size- 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 caps.
- 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.
Competent assembly of the door frame determines phased implementation works:
- 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 equal to the diameter 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 a recess is drilled at a distance of 85 to 118 cm on the side opposite to the loops. desired diameter to install a lock with a latching 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.
- Next, the slopes are carefully shortened in accordance with the dimensions. finished door, observing technological gaps between the floor and the lower part of the door of 15 mm.
- All elements of the box are folded into a design that has the shape of the letter P on flat surface and securely connected with self-tapping screws.
- In the grooves that are intended for mounting the hinge, through hole for fixing 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 they are fixed door hinges, 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. At correct hanging there should be no arbitrary opening / closing of the door.
After the box is securely fixed and the canvas is installed, the wooden wedges are removed from the technological gaps, and the existing gaps are filled mounting foam, having previously closed all installed fittings with masking tape.
Even a novice master if available necessary tools can perform its 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.
Having bought a door frame in a store, you should not immediately despair at the sight of a large number prefabricated elements. To assemble such a design, it is not necessary to be a specialist with higher education. To assemble the door frame with our own hands, we will consider the entire installation process in detail.
Usually, interior doors are sold disassembled, and at first glance, an incomprehensible and chaotic set of elements opens up to our eyes, which includes a profile wooden beam, in the worst case, from MDF, locks and awnings, as well as a canvas. All this is vaguely reminiscent of the children's designer from the do-it-yourself series, and most people, seeing all this, panic and begin to look for an experienced specialist in this field, whose services are very expensive. Other enthusiasts are still trying to solve this puzzle, but their efforts run into big sign question, without detailed instructions very difficult to understand the assembly process. In this article, we will try to help you figure out how to outside help assemble the door frame.
Sizing the box
First and very milestone the entire assembly process is an accurate calculation, to the millimeter, of the length of the loot racks, the threshold (if any) and the upper jumper.
Measurement of racks
The height of the posts must be equal to the height of the door. Usually the standard door size in height is 2000 mm. After making sure of this, we add the width of the gap between the door leaf and the opening to the height of the door leaf by a width of 2-3 mm. In the case of installing doors with a threshold, the width of two gaps of 3 mm in size must be added to the height of the door leaf, a total of 6 mm. In the version without a threshold, we add only one gap of 3 mm in size, and add 1 cm at the bottom so that the canvas does not cling to the floor when opening and closing the doors.
As a result of accurate measurements, we get following parameters: for the option with a threshold, the height of the doors and pillars will be 2000 mm + 2 gaps of 3 mm = 2006 mm; with the option without a threshold, the height of the doors and pillars will be 2000 mm + 3 mm + 10 mm gap = 2019 mm.
Threshold and upper jumper measurement
The size of the threshold and the upper lintel of the door frame must be the same. Let us determine their length correctly, which will be equal to the sum of the width of the door leaf, the width of the gaps between the door and the chute, and the thickness of the profile bar from which the chute will be assembled.
In addition, on both sides of the sections of the jumper and the threshold, it is necessary to cut out landing samples, that is, cut off the protruding parts of the loot, into which the door abuts when closing. The cut should be equal to the thickness of the rack at its widest point.
To correctly cut out the samples, we measure the thickness of the rack from the edge of the jumper on both sides and carefully cut it out with a small hacksaw.
After that, you can screw the door frame with a calm heart.
Do-it-yourself door frame assembly
We screw the door frame with self-tapping screws or confirmations for wood with a length of 55 mm or more. In order to profile beam or the MDF did not crack, you must first make holes of a slightly smaller diameter than the self-tapping screw, approximately 2-3 mm.
In order for the structure to hold firmly and not fall apart during installation, all joints must be fixed with self-tapping screws at least twice.
Marking and inserting canopies
The final step in the installation of doors is the connection of the leaf with the door frame. With the help of a simple operation, this will not be difficult. Having laid the door frame on the floor, it is necessary to invest in it door leaf with awnings built into it.
Place the leaf in the door frame so that the gap is the same on all sides and equals 3 mm. To do this, you can use a school ruler, the thickness of which is just 3 mm.
After the door in the box has been leveled, it is necessary to copy the location of the canopies from the doors to the loot using a marker.
Pull the doors out of the box, put it on its side and use a chisel or router to cut out seats for awnings.
Connect the doors to the frame in single structure and screw the loops to the loot.
The assembly of the door frame is completed. Now the whole structure is ready for installation, and you can say with confidence that you have mastered the puzzle of assembling a door frame with your own hands!
Each master is faced with the problem of how and what to mount assembled doors. To install ready door block application possible various ways installation. Knowing these installation options, you can easily choose the right one for yourself. You will need a small set of tools such as a drill, hammer, level, screwdriver and hammer. Also, to directly fix the box in the opening, you need fasteners and mounting foam. Depending on where you need to fix the door block, you may need self-tapping screws, dowels, anchors.
The main stages of installing a door block
At the very beginning, the old door frame is dismantled. It can be carried out using a nail puller (crowbar), having previously made cuts on both sides of each vertical bar, in order to then squeeze this structure from the opening. If during installation old box were used anchor bolts, nails that are not possible to unscrew, they can be cut off with the help of a grinder.
Before installing the interior door frame, it is necessary to check the verticals of the walls and take into account the differences in the level of the walls and floor. The door frame must be positioned so that if there are irregularities, the wall box does not deepen in the opening. This is necessary to fit the door trim. In order to correctly position the door frame, you should use the building level and take into account all the opening errors.
First, the installations are rigidly fixed in the opening, in order to achieve the initial level of rigidity, wedges are used. After completing the fixing work, it is worth re-checking the correct location of the level so that the box is level with the door.
Working with mounting foam
It is important to know that the foam that is designed for the gun is much better and more convenient to use due to the fact that it is more dosed and has a small expansion coefficient, it hardens much faster. Foam served with a straw large quantity, it will expand longer. Before starting work, it is better to cover the door leaf with masking tape and film, because the foam is difficult to wash. It is important to know that you need to start foaming with the fixation of individual small sections. After 30 minutes, you can already go through the entire perimeter. All cracks are filled with foam (50% of the total volume). Do not fill with a large amount of foam, because during expansion the foam will squeeze the box inside. We recommend using professional foams.
Since the tree shrinks and expands precisely because of high humidity a consequence of the expansion is the deformation of the door block. The door simply stops closing for this reason.
Video on possible door mounting methods
There are several ways to fasten the door frame in the opening, each of which involves the use special kind mounts. Various options fasteners provide a certain level of reliability and strength of the fixed structure. We hope the video stories on the options for installing boxes wooden doors will help you.
Hidden way to install doors on foam
The door frame is fixed in the opening, wooden wedges are used for fixing, and correct location checked by building level. Foaming with mounting foam should be done little by little, in sections and intermittently to avoid deformation. The door frame is kept almost thanks to the foam alone.
To maintain a gap between the frame and the door itself, small spacers of 3 mm are used, which are inserted between the door and the frame. They can be removed only when the foam dries. Usually the door is left overnight.
This method is convenient if you do not need to go into the room, it is fast and does not require much effort. It is important not to overdo it with foam so that you can open the door.
Installing doors with clamps or spacers
The principle of installation lies in the fact that we use inside for temporary fastening of the door block in the opening of the spacer. It can be both ordinary wooden rivers and special adjustable devices.
Both of these methods are very good for light and small doors.
Fastening doors with Knauf hangers
For these purposes, Knauf's direct suspensions, which are used in suspended ceilings, are the best fit.
- First you need to screw the plates to the box.
- Insert the door into the opening.
- Adjust the level.
- We mark the places under the recess in the wall.
- We make a sample under the plate.
After that, we set according to the level and fix the plates. For adjustment, we use wedging with wooden bars.
It is also necessary to take into account that with this method of mounting the box on the outer part of the wall, the place of the recess will definitely need to be hidden under a layer of plaster. That is why this method is good only when there is no fine finish.
New mounting options
This video will let you know how to fix the door frame in the opening. This type of fastening is the installation of an interior door frame by putting the box on the screwed-in heads of self-tapping screws that are located at the ends of the opening. This happens with the help of metal plates with a hole, which are screwed with outer side boxes.
To achieve the final fixation of the box in doorway using the usual means of adjustment.
With this method, the racks of the door block move freely in the opening.
A clear advantage of this method is the full possibility of adjustment and, at the same time, rigid fixation while maintaining original form boxes and exterior finish walls. 
Concealed installation, fastening under hinges
As a rule, for the rigidity of the structure, screws or anchors are used, which are hidden under the hinges. To do this, a hole is made between the screws in the loop and fastened through it to the wall. From the side of the lock, another mount is attached under the decorative plate. As a result, we get 3 fixation points.
After fixing directly, we put a spacer at the bottom of the doors, since the bottom is not fixed and fill all the gaps with foam.
A significant advantage of this method is the relative rigidity, the preservation of appearance.
Through-hole fastening on anchors or screws
This is the most common standard version installation of interior doors. For this mounting option, first, holes for anchors are drilled in the right places of the racks, then the door is fixed in the opening.
Training
- Marking 4 anchors on each side.
- Drilling with a pen 14 mm to a depth of 10 mm (space for a plug).
- We drill a through hole with a 10 mm pen (a place for fixing with an anchor).
After that, the box is exposed and the concrete under the anchor is drilled with a 10 mm drill. When the box rests on its anchors, it holds securely and does not require any spacers. Mounting points can be hidden by installing decorative caps desired color, size (14 mm). Screws can be used instead of anchors, this will reduce the diameter of the plug. The use of this option is the most reliable for heavy doors. With it, you can align (stretch) a curved rail. Doors can be used almost immediately. It is possible to adjust the gap. The downside is the presence of stubs. 
Tricks when installing door extensions
Conclusion
There are many options for installing an interior door frame, but you should choose the one that is the easiest, most convenient and reliable, or the fastest. The choice can be made according to any method of door installation, but these methods can be affected by which opening the installation takes place, take into account the intensity and other factors.
Unlike fully prepared for installation metal doors wooden analogues are sold in a complete set. The explanation is simple - many manufacturers (mainly foreign companies) bring models to market in certain sizes, not for a specific opening, and do not meet our standards. In addition, it is not known in which direction the door should swing open at the installation site.
Therefore, the door frame is represented by bars, from which you still need to assemble the jamb and prepare it for hanging the canvas. Knowing some of the features of "design" will allow you not to resort to the services of hired craftsmen, but to do all the work yourself.
Helpful information
- It is useful to those who, for whatever reason, do not want to purchase a door in furniture showroom, but prefer to make it on their own, according to their drawings. This often happens with non-standard openings; it is much easier to assemble a box of the required dimensions than to expand / narrow the passage. The nuance is in the choice of the width of the beam. It must correspond to the thickness of the wall, and the latter (for buildings erected according to standard project) depends on its material.
Dimensions - in mm. Deviations within ±5 are allowed.
- Brickwork 75 - box 108.
- Log house (log, timber) 100 - jamb 120.
- If an imported model is purchased, then its box is slightly different in size due to a mismatch of standards. Its width varies from 80 to 205. Therefore, you will need to choose a suitable block, focusing on the thickness of the wall at the location of the opening.
What is it connected with? With a significant difference in size, problems with the installation of platbands are provided. There are several solutions - the use of extensions, the manufacture of a "draft" box; but all of them only complicate the installation and increase the final cost of the work.
Box contents
- Loop joint ( vertical post on which the canopies are attached).
- porch ( opposite side box on which the lock striker is mounted, latches).
- Ceiling (horizontal element connecting the racks) It is also called the upper beam.
- Nut (lower jumper; optional part of the design, but some models are equipped with it). It is used if a do-it-yourself door frame is assembled for its installation in rooms such as a bathroom, toilet, and a number of others, where emergencies are possible associated with a breakthrough in liquid communications. The task of the threshold is to prevent the spread of water in adjacent rooms.
Assembly options
The task is to connect the individual parts of the kit into a frame structure rectangular shape. Depending on the presence/absence of the threshold, it takes the form of a closed/open loop. In principle, there is nothing complicated; the main thing is to make a competent installation. When deciding how to assemble a door frame, you need to consider that this can be done in several ways. Which is preferable, you will have to decide on your own. In this case, much depends on practical experience in this area and the tool that is at hand.
baguette connection
Plus - the relative ease of assembly. The technology consists in corner sawing (trimming) of the ends of the fastened elements (450). After combining the parts, the final fixation is made with screws (self-tapping screws).
Minus - limitation in application. It is related to the material of the jamb. For example, it is not recommended to assemble an MDF door frame in this way - it is possible that the edges will “ruffle”, the appearance of cracks and chips.
spike connection
Plus - reliability. This assembly option ensures the durability of the structure, while the door is subjected to constant and significant loads. For example, at the entrance to the building, in places of intensive movement of people.
Minus - self-assembly requires not only experience, but also a special tool. In their absence, no one, even the most detailed one, will help. step-by-step instruction.
Right angle
Plus - it is considered the simplest technique to implement independently, and therefore convenient: a special tool, except for a household one, is not needed. It is only necessary to cut off a certain part of the quarter (depending on the dimensions of the connected elements) and fasten the parts according to the dimensions of the opening. Sometimes this is not practiced - the connection is made end-to-end. The result is expected - the door frame is strong, reliable.
Assembly order
The technique is a right angle. At self assembly it is recommended to fully mount the structure, and only then place it in the opening.
In some step-by-step instructions, a different technology is considered - the preparation and installation of individual parts of the frame in the opening, their alignment with linings and further connection into a single whole. This method is much more difficult, and without proper experience it is better not to practice.
- Preparation of the workplace: free a certain segment on the floor, put together several tables of equal height. The goal is to ensure equal solid foundation. Otherwise, make quality assembly boxes for the entrance, interior door will not work.
- Measuring the dimensions of the opening. Produced in 3 levels (width) and 3 points (height: center and sides). In accordance with this, the required dimensions of the box are determined; there should be a technological gap between it and the walls (recommended within 4 ± 1 mm).
- Open samples. It is done if their dimensions in length do not match the opening. To do this, you need a pencil (draw lines) and a hand saw.
- Pre-assembly of the box. All parts are laid out according to the scheme, taking into account the direction of opening the canvas. That is, it takes into account which side of the rectangle the porch and the loop jamb should be on. After aligning the “shape”, its geometry is controlled, the sizes match, and marks are applied to select a part of the quarter.
- Connection preparation. Notches are made along the marked lines, after which a part of the part is removed with a chisel. To increase the reliability of the joint, the cut is leveled to an ideal state - with a knife, file, grinder.
- Marking for fittings and material selection. It is more expedient to immediately prepare the “nests” for the hinges, the striker of the latch (lock), than to do this after the door frame is installed in the opening. But fasten modern awnings(e.g. "butterflies") should not be. They are fixed on the box when hanging the canvas. The only exception is for loops of old modifications, collapsible; one half of them is installed on the frame during its assembly.
- The connection of the parts of the box. For each "line" - at least two fasteners. The interval between them is chosen so that they are located at least 5 mm from the edge.
Note. If a threshold is provided, then it is placed in a box with the expectation that there should be at least 10 mm from it to the canvas. This is necessary to ensure natural circulation air streams.
It remains only to check the correctness of the geometry, to process the joints in order to eliminate possible differences in height and install the door frame in the opening.
It turns out that there is nothing super complicated in the assembly of the jamb. In the process of work, cutters are not needed, laser level and other special tools(equipment). All that is needed for the "design" of the box is accuracy, attentiveness and marking accuracy.
The door frame is attached to inlet walls and is part door structure, on which a sash is hung with the help of hinges, which serves as an obstacle to entering the room or exiting it. The box is made of MDF, chipboard or wooden beam thickness 75-85mm. With a wall thickness of more than 85 mm, extension strips are used, which are installed in special grooves of the beams. The door frame has a cutout 1/4 deep equal to the thickness of the leaf.
For the installation of hinges in the box, material samples are made by an amount equal to the thickness of the hinged sash. This is necessary for a snug fit of the door leaf to the jambs of the box. Butterfly door hinges are installed without a tie-in.
The door frame is a frame structure. Its vertical components are called jambs, one of which is looped, the other is feigned. The hinge bar bears the main load of the door leaf. The horizontal upper box jumper is called the "lintel", and the lower one is called the "threshold". The threshold in the box is optional. It is installed if necessary to eliminate drafts, blocking the gap under the door leaf. Often doors with thresholds are installed to keep spilled water from entering adjacent rooms. The gap between the floor and the threshold hides the thickness floor covering. Therefore, the assembly of the door frame with the threshold is carried out before laying linoleum, laminate and other materials used to finish the floor.
Types of connections of door frame elements
The whole procedure for manufacturing a frame structure of an interior door consists of connecting individual elements boxes between themselves into one product, having the form of a closed or open circuit, depending on the presence of a threshold. There are three types of connection of the bars of the box:
Tools and materials
Careful assembly of the door frame requires tools and auxiliary materials. You will need the following: 
- Roulette, pencil, masking tape;
- Miter box - a device for cutting timber at different angles. Required for baguette connections and the preparation of platbands.
- Hand saw, drill with wood drills, construction knife;
- Perforator - it is necessary for attaching the interior door frame to a brick or concrete wall;
- Chisel - needed to cut out the places of the box for fastening the loops;
- Mounting foam - necessary to seal the space between the door frame and the opening.
- Acrylic paint for wooden surfaces.
Assembling the door frame
Most home craftsmen choose a simple circuit assembly, which provides for joining the elements of the box at an angle of 90 degrees. To assemble the door frame for ease of use, it is recommended to lay out all the details future design in one horizontal level. This can be done on a cardboard floor, a pair of tables pushed together, or four stools. Correct Assembly door frame implies the following order of work:
From the foregoing, it is noticeable that assembling a door frame with your own hands is not particularly difficult. Positive result work can always be obtained by following the rules of the exact sequence of actions.
