How to calculate the amount of timber per house, assembling a house from a timber. Preliminary calculation of materials for building a house from a bar Calculate the volume of a bar for a house

Building a house from a bar opens up a lot of advantages for its owner, the main of which is the environmental friendliness of the chosen material. The process of calculating and choosing the material precedes the construction of the house, and we will talk about it further.

Timber house - varieties and advantages

Making houses from timber is becoming more and more popular. Since this material is harmless, and even beneficial to health. Living in a house made of wood has a beneficial effect on well-being. Since, wood is able to regulate the optimal level of humidity in the room.

For the manufacture of timber, solid wood is used, from which rectangular beams are cut. The most commonly used material is coniferous trees. Since they are distinguished by the highest level of resin content, which makes the material more durable and prevents it from rotting, thereby increasing the service life.

There are two types of timber:

• ordinary type;
• profiled.

The standard type of timber is a timber with a square or rectangular section. The procedure for manufacturing profiled timber is more complicated, as it requires cutting out locks, grooves and ridges. This beam is more convenient in connection and the room that is made from it has the highest thermal insulation characteristics.

In relation to the structure and production technology of timber, the following material is distinguished:

• whole;
• glued type.

For the production of the first version of the beam, the presence of solid trees is required, from which the beam is cut. To make a glued-type beam, it is necessary to have boards of a certain size, which are glued and pressed together. For additional resistance to decay, antiseptics are applied to the boards, and then interconnected with resin. This type of timber is more resistant to cracking, but not fireproof enough. It is possible to manufacture glued laminated timber using various kinds of wood, for example, spruce and pine. In the process of gluing, the main thing is not to allow the fibrous parts of the boards to coincide with each other, since the beam, in this case, becomes less durable.

In addition, in the process of manufacturing glued beams, boards on which defects are present are not used, but replaced with new ones.

The most important and indisputable quality of any type of timber is its environmental friendliness. Since for its manufacture solid wood is used, which has all the useful properties of natural wood. If we compare glued and solid timber, then the second option is more environmentally friendly, since the resins used for gluing glued timber emit toxic substances in small quantities.

Although in architectural terms, the use of glued laminated timber is more convenient. Since with its help it is possible to build buildings of any shape. The standard length of glued laminated timber is 6 m, but there are cases when logs reach a length of 15 m.

A house made of profiled timber allows you to hide communications by cutting out special niches. The building, in the process of manufacturing of which glued laminated timber is used, is more fire resistant, since in the process of its manufacture each of the boards is impregnated with fire-resistant mixtures, which make it incombustible.

Among the disadvantages of making a house from a bar are:

• if the material is not properly dried, it is not able to perform all its functions with high quality;
• requires constant application of impregnations that improve its quality characteristics, otherwise, the tree begins to rot and deteriorate;
• glued laminated timber has a very high cost, which is its big drawback, although it is fully justified by the complexity of its manufacture and durability in operation.

How to calculate a beam: features of the implementation

When buying a bar, its cost is measured in cumobetry. Therefore, this unit is also used for glued calculation beams or edged boards. To determine the amount of material needed, you should first find out its size. For example, with a width of 15 cm, a length of 6 m, and a thickness of 10 cm, the number of logs is determined by dividing one cubic meter by the volume of the timber. One cubic meter of this timber contains 11 logs.

The calculation of the amount of timber per house involves the determination of materials for its various sections.

The first to be calculated are the ceiling and floor beams. When building a house on unstable ground, it is advisable to replace the floor on beams with a monolithic base. Otherwise, the use of wood is recommended. The standard size of ceiling and floor type beams is 10x15 cm. Their laying step is not more than one meter. To ensure maximum strength, the beams should be cut into each other in a vertical position. To calculate the total length and number of required beams, you must perform a series of actions:

• divide the total length of the house by the step of laying the beams, and then subtract 1.

For example, if a house has a length of 6 m and a width of 5 m, with a laying step of 1 m, the beams are calculated as follows: 5/1-1=4 pieces.

The beams are produced in a standard length of 600 cm, which is the same as the length of the house.

The next stage is the calculation of the cubature of the beam, for the construction of the truss system. We offer an example of a calculation option for a straight gable roof. In this case, the installation step of the rafter is 600 mm, and the angle of inclination is 45 degrees. For the manufacture of rafters, a material with a cross section of 10-15 cm is used. Please note that with an increase in the angle of inclination, the amount of snow that accumulates on the roof in the winter decreases, and the load on the building decreases, although the resistance of the roof to the wind also becomes less. Therefore, for regions with increased windiness, it is recommended to build a roof with a low angle of inclination, and in places with a lot of precipitation, in the form of snow, it is better to give preference to a roof with a high level of inclination.

In order to equip the rafter system, you must first install two rafter legs, and then fix them with a bar. Next, the rafters are installed.

If the value of the run of the house is 1000 cm, and the angle of inclination is 45 degrees, then in order to calculate the length of the rafter leg, it is necessary to calculate the sum of the legs squared. This value will be 424 cm. For the construction of each triangle, you will need to purchase 850 cm of material.

To calculate the number of triangles, we divide the total length of the roof, which is 1000 cm, by the laying step - 60 cm, and subtract one, we get 16 pieces. Now we multiply the number of triangles by their length - 16 * 850 = 13600 cm. In addition, one should not forget about the run, which is 1000 cm, we add it to the main value and get 145 m of wood. If the cross section of the beam is 5x15 cm, then to calculate the number of cubic meters, you need 145 * 0.15m * 0.5 \u003d 10.9 cubic meters.

The calculation of the beam load on the surface of walls, gables and internal partitions is carried out in relation to the building project. When carrying out the calculation, one should proceed from one approach to calculating the material for internal partitions and walls. All elements should be converted into geometric shapes and, based on the formulas for each, determine their area. If there are openings in the form of windows and walls, their area should be determined. Subtract the opening area from the pre-calculated wall area, multiply the resulting value by the wall thickness and you will get the amount of material that will be needed to build the wall. After calculating the value for each of the walls, summarize the results.

The calculation of the strength of the timber depends on its weight, which is affected by the rock and humidity. The latter value is determined by the percentage of the amount of water in the tree. The humidity value determines the quality of drying and storage conditions of the material.

Dry wood is a material that has been dried under technological conditions, or stored in warm and dry rooms for a long period of time.

Raw wood is called a tree that begins to dry. If the material contains equilibrium moisture, then it is classified as air-dry wood. When the material is stored in conditions of high humidity, it takes the form of a wet or freshly chopped tree.

The construction of a house with the use of timber is easier to carry out calculations, compared with houses made of logs. In addition, the use of timber opens up a large number of options for finishing both the interior and exterior of the building for the owner of the house.

In relation to the cross section of the beam, materials are distinguished: 12x12, 15x10, 18x18, 20x15, 15x15, 10x10, 14x14. The most optimal size of timber for building a house is 15x15 cm. Since it is this type of timber that has an acceptable cost and high thermal insulation characteristics. In addition, this beam is easy to install and easy to operate.

The use of profiled timber with such a section will allow you to build an excellent house that will serve its owner for many years. The only drawback of this beam is its high cost, therefore, when calculating a profiled beam, you should be extremely careful not to make a mistake and not spend a lot of money.

To correctly calculate the amount of material with which you want to build a house, use the formula:

A * B * C \u003d number of timber

A is the length of the wall;

B is the height of the wall;

C is the thickness of the material.

For example, for the construction of a house, the length of which is 8 m, and the width is 6, using a beam with a section of 15x15, calculations are carried out according to the formula: 2 (6 + 8) \u003d 28 m - the value of the perimeter. The height of the wall is three meters, so this value is multiplied by the perimeter, we get 54 m. Now we multiply the result obtained by the cross section of the beam, which is 0.15 m, we get 8.1 cubic meters. Therefore, this will be the value of the amount of timber needed to build a house.

How much timber is needed to build a house

Factors on which the amount of timber for the house depends:

• type of timber used in the construction process;
• the amount of timber in one cubic meter;
• house design.

To calculate the amount of timber for the outer and inner walls, use the algorithm:

1. Calculation of the perimeter of the building.

2. Multiplying this value by the total height.

3. Multiplying the result obtained by the cross section of the beam.

4. It turns out the amount of cubic meters of material needed to build the building.

In the process of making calculations, attention should be paid to the fact that the device of the first crown will require more material, since its width must be increased. In this calculation algorithm, this condition is not taken into account, therefore, to calculate the bar of the first crown, a separate formula must be applied.

The cross section of the beam for the first crown should be chosen more than the main one, since it is this crown that is bearing and takes on the entire load from the building. In addition, it requires additional processing with engine oil or an antiseptic solution.

When the calculation of the beam for bending is completed, the procedure for determining the number of pieces of timber for building a house follows. This value will help save time during the material purchase process. In addition, in this way it will be possible to avoid fraudulent actions on the part of the seller.

We suggest that you familiarize yourself with the main values ​​\u200b\u200bof the quantities of timber in one cubic meter, taking into account the length of the material of 6 m:

• 10x10 cm approximately consists of 16.6 pieces;
• 10x15 cm - 11 pieces;
• 15x15 - 7 pieces;
• 10x20 - 8 pieces;
• 15x20 - 5.5 pieces;
• 20x20 - 4 pieces.

To determine the amount of timber in pieces, the total value, for example, 14 cubic meters, should be divided by the volume of one piece of timber in a cube. To calculate this number, you need to divide the cross section of the beam by the number of pieces in one cube. For a standard timber size of 15x15 cm, this is 0.13. 14/0.13=107.6 pieces.

When setting the number of pieces needed to build a building, there is no need to accurately measure each cubic meter when buying material. Enough piece-by-piece counting of the material.

The height and width of the beam play an important role in the construction and operation of the building. In a higher beam, the interventional seams are reduced and the construction procedure is accelerated. When choosing the optimal width, the need for permanent or temporary residence in the house is taken into account. The minimum thickness of the timber recommended for the construction of a building in which people will permanently live is 20 cm. At the same time, to improve thermal insulation, foam or mineral wool is used, laid in a layer of 10 cm. If it is planned to build a bath, then the layer thickness should be increased to 16 cm.

In the process of building a country house, in which people will live only in the summer, it is enough to purchase a beam with a section of 10x10 cm.

When calculating a stepped beam, an important factor is the preliminary design of the building. It is on the project that both the external and internal views of the house, the number of walls, doors and windows are displayed.

There are several options for obtaining a project:

• its own production;
• order from specialists;
• purchase on the Internet;
• project purchase;
• use of the finished project.

To independently create a project at home, you need special skills in working with drawings. For its compilation, the climate in which the house is located, the soil on which it is based, and other factors are important.

Therefore, the most correct solution would be to hire specialists who are able to take into account all the individual characteristics of the site.

Remember that when calculating a timber for building a house, it is better to buy material with a small margin than to stop construction work due to its lack.

The online timber calculation calculator is designed to determine the required amount of timber and additional materials for building a house. Also, when calculating the timber online, you can take into account the cost of fastening, impregnation for fire protection and roll insulation. Correct calculations will allow you to avoid additional costs for the purchase of excess building materials and avoid problems with their shortage during the construction of the house.

The lumber calculation calculator provides for determining the type and quantity of fasteners, wood protection impregnation and insulation. It is possible to understand the estimated cost of timber and consumables needed to build a house. The area of ​​the doors and the area of ​​the windows are deliberately not subtracted, since they must be cut out after the structure shrinks (in the doorways it is partially cut out to organize the passage).

The online calculator for calculating the beam determines the load from the walls from the beam to the foundation, which is very important at the construction planning stage. This construction calculator will allow you to avoid unnecessary expenses for the purchase of building materials and avoid problems with their shortage during the construction of a house.

There is a lot of talk about the fact that they have a lot of advantages. The characteristic features of the material under consideration are the correctness of forms and usefulness for the general living space. That is why the most important component for a correctly built house is a normalized calculation of the amount of material required. You can calculate the amount of timber per house on your own, without consulting specialists.

Of course, you should not avoid the advice of professionals, as they will be able to establish indicators in a short time and with incredible accuracy. For correct calculations, it is necessary to determine the required volumes, and find out how many components you need to take per square meter.

Thanks to the final results obtained, you can freely navigate the price range and future waste.

Calculation of the amount of materials

In order to make the calculation process more convenient, you need to use some list of simple tools:

1. Regular pencil;
2. paper sheet;
3. Calculator;
4. Roulette.

It is important to know that the indicators given in this article are approximate. Therefore, for a particular construction, it is worth using your own data.

The most accurate pictures are compiled during the planning period and the availability of the final project of the future structure.

1. Measurement of the entire perimeter of the future building;
2. Multiplying the perimeter by the floor height of the house;
3. Multiplying the acquired numbers by the thickness of the material used;
4. The resulting total number of cubes is an indicator necessary for construction.

If, in addition to the walls, it is planned to build internal partitions, this factor must also be taken into account in the calculations. If necessary, obtain indicators not in cubic meters, they can be easily converted into units.

The specific moment is determined by dividing the total volume by the volume of a unit of production.

Counting example

Suppose you want to install a one-story structure with dimensions of five by seven cubic meters. In addition to this, you need to install a partition together with. The total ceiling height is equal to three meters. As for the pediment, it also consists of a direct beam.

When performing activities, a tree is used, endowed with a section of 150 * 150 millimeters. In this case, the calculations will be as follows:

1. 33 meters / (5 + 7) * 2 + 5 - this is the immediate perimeter together with partitions;
2. 33 * 3 * 0.15 \u003d 15 square meters - these are the total volumes of the wall surfaces of the first floor;
3. 5 * 3 * 0.15 = 2.25 square meters - pediment volumes.

Having received all the above indicators, it is necessary to sum up. In this case, it is shown that 17.25 square meters of material is required for wall surfaces.

This is all taking into account window openings, doorways, beams and, of course, ceilings. It is important to remember that components should be purchased with a small margin.

Summing up, we get a total cubic footage equal to 25 square meters.

Dimensions of required materials

Sufficiently significant parameters are the thermal conductive properties and, of course, the thickness. In the production of a summer house or cottage, necessary for regular living there, it is better to use materials with different thicknesses.

In the case of a summer country cottage, the width and thickness, in principle, does not really matter. Here it is possible to use materials endowed with a cross section of 100 * 100 millimeters. In the case of a cottage, you should pay attention to beams with a section width of more than 150 millimeters. Of course, additional thermal insulation of wall openings is also required.

The specific number of elements required for the construction process depends on the thickness parameters. If you want to save on the purchased material, you need to remember about the not quite high-quality thermal effect obtained in the future.

For the construction of an insulated building, it is necessary to use beams with a thickness of approximately fifty centimeters.

A similar result can be obtained with the use of sections of 150 * 150 millimeters, as well as insulation of ten or fifteen centimeters.

Log houses have a number of advantages in comparison with wooden log houses. Due to the fact that the timber has a geometrically regular shape (it is either a square or a rectangle in cross section), much more usable space appears in the house, it is much easier to calculate the amount of timber needed to assemble the walls.

To do this, you need to add the lengths of all the walls, multiply by their height and the thickness of the beam, consider an example of the formula:

V timber = wall length X wall height X timber thickness

We get the number of cubes of timber needed to build a house.

The correct calculation of the beam on the house

Calculate the required amount of timber per house house 6x9, with a fifth wall, 3 meters high, from a timber 150x150, for this we add the perimeter of the walls, not forgetting the fifth six-meter wall 6 + 6 + 6 + 9 + 9 \u003d 36 running meters, then multiply by floor height (3 meters), 36 linear meters. m x 3 meters = 108 sq. meters, in order to get cubic meters, we multiply the resulting area by the thickness of the beam 108 sq.m. x 0.15 \u003d 16.2 cu. meters.

That's basically all, now it should be clear to you how to make the correct calculation of the necessary timber for the house, according to the above described scheme, even a schoolboy will figure it out.

Now let's talk about how houses are assembled from a bar

On an already prepared foundation, we lay in 2 layers any waterproofing material, such as roofing material or roofing felt. Mortgage boards treated (necessarily!) with an antiseptic are laid on top. These boards serve as a protective buffer between the foundation and the first row of timbers. If during operation it rots at the base of the house, then these will be the embedded boards (they can be replaced), and not the first layer of beams.

Laying the first crown

The next step is laying the first crown of the building. The main thing here is to carefully observe the dimensions of the building along the axes, the horizontal level and measure the angles planned by the project. Here it is also necessary to decide in advance which angular interface for the beam will be used when laying it.

The corners are checked with twine stretched diagonally from corner to corner and its length is measured. Then also stretch diagonally between the second pair of corners. If the distance matches, the next crown is laid. If there is a mismatch, the distance is corrected. In professional construction organizations, for these purposes, they do not use improvised means, but special high-precision engineering tools.

Before assembling the first layer of timber, one of the following types of wall corners is selected:

• assembly in half a tree;
• assembly in dressing with a root spike;
• dowel assembly.

Laying subsequent crowns

The second and subsequent layers of the beam are interconnected on wooden pins (dowels), which are a wooden rod, thanks to which the crowns are attached in height. Such fixation excludes displacement and buckling of the building material during shrinkage.

The hole for the dowel is drilled a few millimeters in diameter larger than the dowel itself, so that the beam, during subsequent shrinkage, can freely “walk” along the dowel, thereby preventing the formation of cracks.

Building a wooden house requires careful preliminary calculation and preparation of the most detailed estimate. Any large construction project is associated with significant costs, and it is important to initially correctly assess the financial possibilities and present all future costs.

An important expense item is the foundation, but the “box” itself will become the most expensive part, so you need to perform a preliminary calculation of the material for a house from a bar. In this case, it is advisable to consult with a professional architect and builders who know the real prices on the material market.

Which timber to choose for construction

First you need to choose the material for the house from the timber. It differs both in characteristics and in cost:

• The cheapest option is the usual bar of natural moisture. It is the most common, but the least reliable. During the drying process, it can significantly deform, which leads to the formation of cracks and crevices in the walls.
• Dried timber - wood material that has undergone preliminary chamber drying. Most of the natural moisture is removed from it, so it will be more reliable, but the cost will also increase significantly.
• Profiled timber is an even more expensive type of material that will allow you to build completely smooth walls without gaps between the crowns. A special system of spikes and grooves on the top and bottom sides will allow you to build a building with the most durable walls.
• Glued laminated timber - the leader in cost. This is not exactly a bar, since it is not made from solid wood, but from several layers of wood glued together. Such material requires long processing, and it will be very expensive.

Thus, the calculation of material for building a house from a bar begins with an analysis of the construction market and the choice of a suitable material. When this issue is resolved, you can proceed directly to the calculations.

How much material is required to build a log house

The calculation of the material for building a house from a bar can be carried out using a special calculator program that is posted on construction sites. This will speed up the calculation, but the result will still only be an approximation. You can also calculate the material manually using the following parameters:

1. Bar section. It depends on the required thermal conductivity: for a house without additional insulation, a beam with a section of 200x200 mm is required: it is quite expensive, so future owners often prefer to purchase thinner and cheaper material, and then insulate the building with inexpensive materials. It is permissible to build a building for permanent residence from a bar with a thickness of 150x150 mm or 150x100 mm.
2. House dimensions. The standard project is a building made of timber 6x6 meters in size, as it will allow you not to connect the timber to each other.
3. The height of each floor. The minimum height from floor to ceiling is 2.5 m, often it is made higher so that later you do not limit yourself in the choice of furniture and finishes.
4. Area of ​​window and door openings. It is clear that the larger the window area, the less material is required. When developing a building project, the dimensions of the openings are indicated in the drawings, these values ​​\u200b\u200bare used for calculations.

An example of calculating materials for a standard house

It will be of great help in calculating the required amount of timber for building a house. But let's try to perform simple calculations on a simple example.

The calculation of materials for a house from a bar requires making fairly simple calculations that make you remember school geometry lessons.

Preliminary calculation of the material for a timber house:

It is required to build a small house with linear dimensions of 6x6x2.5 meters. For construction, you need to purchase an ordinary bar with a section of 200x200 mm. It is planned to make a door with an opening size of 800x2000 mm in the building, in addition, it will have two windows measuring 600x800 mm.

Let's move on to the calculations:

• The perimeter of the house: 6 * 4 = 24 meters. We multiply this value by the height: 24 * 2.5 \u003d 60 square meters. meters - the total area of ​​\u200b\u200bthe walls.
• We calculate the area of ​​windows. We multiply 0.8 * 2 \u003d 1.6 square meters. m. - door area, 0.6 * 0.8 * 2 \u003d 0.96 m. - area of ​​\u200b\u200btwo windows. These values ​​​​must be subtracted from the total area of ​​\u200b\u200bthe walls: 60 - 1.6 - 0.96 - 57.44 square meters. m. - this is the area of ​​\u200b\u200bthe house.
• Since the thickness of the timber is 0.2 meters, the volume of the walls is calculated as follows: 57.44 * 0.2 = 11.488 cubic meters of timber will be required for construction.

Important points when calculating the material

If you need to build a house from a bar, the calculation of materials will always be approximate. It is imperative to add at least 15% to the obtained value, which will be required for trimming, damage, arranging corners, etc.

The timber is required not only for the construction of the box, but also for the installation of rafters, floor logs, ceilings, etc. As a result, in the final calculations, the amount of timber increases by about a fifth.

The exception is the construction of a house from a finished house kit. In this case, together with the architect, the exact amount of materials that will be required for construction is calculated, and all parts are pre-treated in the factory.

A ready-made set of numbered parts arrives at the construction site, from which the building is being erected, like a large constructor. All the details are exactly adjacent to each other, nothing needs to be adjusted and modified. You will have to buy only fasteners and insulation, and the work can be completed faster.

The calculation of lumber should take into account not only the purchase of the timber itself. You will need an inch board for the construction of a rough and fifty for a finished floor of a given area, material for the construction of a roofing pie and other expenses.

Each wooden element used in construction must be treated with antiseptics and fire retardants, the finished house needs to be painted or otherwise finished. The walls can be sheathed with drywall and additionally insulated.
