How to calculate the construction of the house from the bar. Calculation of the construction of a house from a bar

B Rus is a rather popular material for the construction of a bath in the country, thanks to the relative cheapness and technologicality. You can build a bath from or from glued timber without special knowledge and special experience. You can spend one day in a brigade that builds a bath and you can assemble the walls from the bar on your own. Of course, much depends on the quality of the source building material and common construction skills.

Methods for calculating the number of timber

In order to correctly calculate the required the number of timberYou can apply several ways to build walls of a bath wall, each of which, unfortunately, will give only an approximate result that the quality of the sawn timber will not be able to take into account the quality of the lumber.

If a bad quality bar falls in the party, it will have to either replace, or use to other economic needs. The calculations are not taken into account openness, and door and window. After the calculation, the volume of the bar should be added, which will go on the floor beams and overlap, on the rack or frame on the veranda.

If the walls inside the bath have the same thickness, then they are considered together with the outer, if the boll of a smaller cross section goes on the partition, then we consider it separately. After the final calculation to the final amount add 10 more - 15% - it will be a more accurate figure that will reflect the real need for a bar.

We consider and get Cuba

We find the total length of the wall from the bar, we multiply it on the height of the wall and the resulting digit multiply on the wall thickness. For example, the length of the carrier wall on the project of the bath from a bar 6x6 m with a warm veranda is 34 m. The height of the wall - 3 m, the bath will build from a bar of 150 mm (0.15). Multiply, we get 15.3 cubic meters.

We consider and get things

As in the first embodiment, we find the length of the bearing walls - 34 meters and divide it on the length of the bar, which is always 6 meters. We get a figure denoting the amount of timber in pieces, which goes on the laying of 1 the crown of the bath 34/6 \u003d 5.67 pcs. The height of the walls is 3 meters, which means there are 20 vendors of the bar of 150x150. 20x5.67 \u003d 113.4 pcs. Bruus.

Checking the correctness of the calculated calculations

We check the calculations we obtained in a simple way. It will give us complete confidence in their correctness. In one cubic meter 7.4 pcs. Bruus 150x150. We take and compare our previously obtained data: 15.3x7,4 \u003d 113.22 pcs. Bruus.

The result is rounded into the biggest side 114 pcs. And add 10% - we get the amount of timber for the construction of a bath from a bar 6x6 for this project. Do not forget about the beams of the floor and overlap.

Data required for settlement

• Length of the bearing wall of timber;
• The height of the construction wall;
• Wall thickness.

The length of the wall can be found by simply adding all bearing walls. If the bath has a complex configuration, then its plan can be drawn on a sheet into a scale on a scale and a ruler to measure the walls.

Wall thickness - size in the width of the bar, which will be used during construction.

Height on average is better to choose 3 meters. Taking into account the shrinkage of the bathhouse by 15 cm, the ceiling, the ceiling height will turn out to be just 2.3 meters and this is provided that the floor beams will be at the level of the first bar, and the rafters lie on the walls. The height will decrease with the finishing trim of the ceiling by 10 cm plasterboard and 5- 8 cm by floor when finishing.

The wall thickness is the size in the width of the bar, which will be applied during construction.

An example of calculating the number of bars for a bath of 6 sizes to 9 meters

Calculate for example how much timber is required for a bath 6 m per 9 m, with two internal partitions from the same bar. We consider the thickness of the wall 0.15 meters. Estimated building height: 3 meters.

• The total length of the wall of the bar in the bath: 6 x 4 + 2 x 9 \u003d 42 meters
• We multiply the length of the height and thickness of the wall: 42 x 3 x 0.15 \u003d 18.9 cubic meters of 300 to 150
• Building the length of a bar is 6 meters. In 1 cubic meters 7.4 pcs. Such a bar. Multiply 18.9 x 7,4 \u003d 140 pcs. Bruus 150x150 6 meters long.

If the beams of overlaps on the floor and the ceiling will be from the boards, then this number of timber will be enough. If not, then the bar should be taken into account on the beams, which are set through each meter and for such a bath it may be necessary to take more pieces 14, which will be 2 additional cube of the bar.

And a brief "reminder" of the number of cubes in a bar (board) of coniferous rocks of various ratios of width and thickness for 10 meters long products. It will help check the calculations made and will not allow mistakes.

Table of calculating the number of timber in cubes with various parameters, volume in 10 route meters

The bar is really a good modern choice for building a bath in the country or country site. High-quality, correctly harvested and processed material will last for many years, and a careful attitude towards it and periodic processing with special compositions will make your bath with almost "eternal".

Many think about the construction of a country house, but most postpone it for tomorrow in connection with ignorance, how to calculate the number of timber to the house. Why? Yes, because the counting process itself is not free, but pay for what may not be implemented - no one hunt.

Let's try to understand with you how to correctly calculate the amount of this product for the construction itself.

Calculation of products for building buildings

Factors that affect numbers

The main thing is that it is necessary to take into account when calculating the amount of material on the house is:

• what kind of timber will be used in construction;
• how much we need it;
• how many pieces in 1 cubic meter;
• what.

Calculation of lumber in cubic meters

Consider how to calculate the number of timber in Cuba in the easiest way, one can say this is the main principle of calculations. It should be noted that the example is not accurate. To carry out more accurate numbers, you need to have a project of the future at home.

So, attention instructions:

1. Calculate the perimeter of the building.
2. Multiply the perimeter to height.
3. The result is multiplied by the thickness of the product.
4. As a result, the result of the number of bar cubes required to build a building was obtained.

To calculate the product for inner walls, we use the same method. If desired, it is possible to calculate not only the material cubage, but also its number in pieces. Consider a separate example, how to calculate the number of timber on a bath 3 m at 5 m high 3 m.

We agree that during construction will be used in size 150 by 150 mm.

Instruction:

• (3 Width + 5 Length) × 2 \u003d 30 m is the perimeter of the building.
• 30 perimeter × 3 Height \u003d 90 sq. M - wall area.
• 90 Square × 0.15 Material thickness \u003d 13.5 cubic meters - you need to build a box with a bar 3 × 5 with a height of 3m.

Thus, the number of vehicles for the walls is 13.5 cubic meters. But, it should be noted that the window and doorways will reduce the amount of material used.

In most cases, the masters do not take into account the moment, it is believed that even better to throw about 20% of the margin, as a result, we will succeed:

• 13.5 + 20% \u003d 16.2 cubic meters. We will need for this type of building.

Note!
When building a house from a bar, the first crown should be a little thicker than the main product used to build walls.
In our count, it is not taken into account, it is necessary to calculate it separately.
The first crown is laid out of the thicker, as in the future it will fall on it the mass of the whole house, it is additionally recommended to process it with machine oil or antiseptic.

Calculation in pieces

Having calculated how many lumber cubes for the construction of the house, you can easily find out how much a bar is needed in pieces. It is necessary first when buying. Knowing the exact number of pieces, you will protect yourself from possible fraud from the seller.

Consider the table of common sizes of this product length 6m:

On the above example, where we marked the cube of a bar for a bath, we will carry out further calculation of materials in pieces.

So, in order to find out the amount of material to the house in pieces, we carry out the following calculation, for this, a system of 13.5 m.kub, which is needed for the construction of the bath, divide into the cubic volume of the used bar, in our case it is equal to the table 0.135 M. Kub :

• 13.5: 0.135 \u003d 100 pieces

Knowing the right amount of product in pieces, you do not have to go to run with a tape measure and calculate the volume to find out whether you got the material on the invoice, you will only need to calculate the product.

The role of the height and thickness of the material

Before calculating the amount, you need to decide on the choice of thickness and height of the product.

The material may have different thickness and height, list the main dimensions:

• 100x100 mm.
• 100x150 mm.
• 150x150 mm.
• 150x200 mm.
• 200х200 mm.

With a height, everything is simple, the higher the bar, the smaller the interventic seams - construction work undergo faster, and naturally, the number of pieces of material for the construction of the house decreases. But the width is more important, especially during construction for all-season accommodation.

Note!
Not all lumber manufacturers are honest with the buyer, sometimes it happens that the ram 150x150 mm actually has a size of 140x140 mm.
What will lead to, it is not difficult to guess if a height of 150x150 mm in size is needed at a height of 3 meters 20 pcs., Then at a rate of 140x140 mm - 21 pieces and a half, and this is a half of the weft row.

When planning year-round accommodation in the house, it is recommended to use a timing of 200 mm thick. It is necessary to warm such walls, but for our climate there are enough such a foam or mineral wool with a thickness of 10 cm.

When building a bath, it is recommended to use a thickness of a material of 150 mm, it is enough for short-term maintenance of temperature. Well, if you decide to build a country house for a summer holiday, then in this case the walls from the bar 100x100 mm will be just right.

Tip!
When building a wooden house, in which it is not planned to stay all year round, the thickness of the bar is not important.
After all, such a building is only necessary for short-term use and mainly in the spring-autumn period.

Pay attention!
Despite the large thickness of the product, the walls will still have to warm the walls.
After all, in order for the house fully fulfilled its thermal insulation properties, the wall thickness should be about 50 cm.

Why do you need a project of the house

When calculating the material for the construction of the house, the project of the house is played an important role. After all, only in the finished project you can see not only the appearance of the building, but also the inner location of the walls and elements that need an additional calculation of the required material.

Get a project of a wooden house in different ways:

• do it yourself;
• order from a specialist;
• buy a finished project;
• buy on the Internet;
• find on the Internet.

You can make your own hands the project at home, but it is difficult, as you should have special knowledge. And the point here is not only to draw a future house, you need to take into account the specifics of climate, soil, air humidity and other points.

The most correct solution is to order a specialist project, the price of such services is not cheaper, but this is the best option, the specialist will take into account all your wishes and the possibility of terrain. This will protect against many possible troubles, and will also ask anyone when there is problems.

Tip!
Do not buy projects on the Internet from untested persons, most often they sell those projects that are posted on the Internet for publicly available use.

Output

Making the right counting, you will provide easy construction. It will not be necessary to think later - where to do extra products or, worse than the construction of construction because of their shortage.

If you have some other questions, see the video in this article, you will not only learn how to calculate the timber on the calculator, but also be able to calculate the approximate cost of the future at home. You definitely will not be any doubt in your ability to calculate the material with your own hands.

Lumber suppliers, measured it in cubic meters (M 3) and the price is respectively indicated for 1 m 3. Calculate sawn timber in Cuba (cubature), find out the number of boards, knowing their size will not be difficult with this calculator.

Specify the dimensions of one board or bar in millimeters:

W. - The width of the board or timber, is chosen by you based on the use of lumber. According to GOST 24454-80, lumber width can be from 75 to 275 mm. Select the optimal value of the width should be tailored to the joint venture 64.13330.2011 (updated edition of SNIP II-25-80).

H. - The thickness of the board, the important parameter of the cross section of the material. Thickness, according to the above standard, can be from 16 to 250 mm. Take into account the joint venture 64.13330.2011 "Wooden designs" to establish value H..

The timber is considered a lumber with a thickness and width of 100 mm, attitude H./W. Not less than 1/2.

L. - The length of the board depends on the length of the source logs (i.e., if a 4000 mm long billet is cut, then the board will be the same value). Value L. It may vary from 1000 to 6000 mm.

E. - Quantity in cubic meters - This item must be selected if you want to know how many boards of a certain size will result from a given number of cubic meters of wood.

Also indicate the cost of 1 meter of cubic lumber in your area.

Opening Results Online Calculator Lumber

If you specified the parameter N. (i.e. how many pieces), the calculator will calculate what volume the wood must be cut to obtain a given number of boards. And if the parameter was specified E. (i.e. volume) will be counted how many pieces of boards can be obtained from such a volume of wood. Will also be calculated which volume is one board or timber (with parameters W., H., L. Chosen by you) and how many in one cubic meter pieces of boards (timber) of this size. If you have led the rates in the relevant paragraph, the total cost of sawn timber will be calculated, their volume and quantity. These data will be useful when drawing up estimates.

With a thorough inspection, a certain number of sawn timber can be selected due to defects. Therefore, so that at the final stage of construction did not have to buy the board, it is necessary to make a small stock over the calculated quantity (approximately 10-20%).

The construction of the house is always associated with significant financial expenses. However, that the costs do not exceed the assigned limit, and the materials were purchased in sufficient quantities, it is necessary to calculate the cost of building a house from a bar.

Regardless of that on its own it is planned to build a home or for this will be hired workers, you need to make a estimate. This is the basis of all work.

Formula Currency Conscent Bruce For Bearing Wall Houses

The calculation of the bar for the construction of the house passes by the formula:

1. the sum of the lengths of all the walls of the structure, not only external, but also internal is the perimeter;
2. the perimeter is multiplied by the height of the house, excluding the frontion area (the facade of the building, limited by the roof and cornice);
3. the value obtained as a result should be multiplied by a timing of a timber selected for construction.

As a result, it turns out the number of cubes required for the construction of the house. Usually limited to one, less than two floors.

It is convenient to consider the formula on a specific example:

Total: to build a house of 13.5 m. Brous cube with a cross section of 150 * 150 mm. If the walls are assumed more, they are also taken into account in the calculations.

For the convenience of calculating and facilitating the purchase process, you can use the data below, with a length of 6 m:

To properly hold the construction of the house from the bar, it is necessary to take into account the moment that cannot be avoided during individual construction - even several marriage units may be in one batch. This must be taken into account when buying and acquire blanks with a small margin.

It is better to take products from one party, otherwise problems may arise during the docking of the elements due to a different way of processing and its quality.

Stage Second: consumption material for roof frame

For a home bar, a rafter system is used - this is the carrier roof frame. A tree is a durable material, but it should not be overloaded so as not to provoke an uneven shrinkage and the destruction of bearing walls.

Factors affecting the amount of material required for roof frame

So that the roof is not only beautiful, but also reliable, you can not save on building materials. It is necessary to strictly follow the technology in its independent structure.

Wooden roof frame includes the following required elements:

• stropile legs, or just rafters;
• fRONTON, is performed from the bar in the same way as carrying walls;
• lags (beams) - horizontally located bars, the basis for which the flooring is stacked;
• maurylalat is the fattest bar, located around the perimeter of the walls, is intended for a uniform distribution of the weight of the roof frame;
• doom - attached to rafters and serves as the basis for laying the roof.

SNiP 31-02 places a number of requirements for any roof, based on which materials should be calculated to build a house from a bar. That is, that the framework corresponds to the stated standards and defended the structure from snow, melting and rainwater, did not miss the cold air, it was necessary to figure out how much blanks will need.

How to calculate the number of building material for the frame: Mauerlat

The amount of material directly depends on the coating area. As an example, consider the house 6 × 6. For a reliable base, a thick strong beam is required with a cross section of 150 * 100 mm or 150 * 150 mm. It is placed on 4 bearing walls, respectively, to build Mauerlat 4 bars 6 m each.

Note! If the structure does not imply inner bearing walls, then the distance between them should not exceed 8 m. If there is another support within the house, then the distance increases to 14-16 m.

To calculate the number of timber at the length of the wall greater than 6 m, it is necessary to calculate the total perimeter metra:

For example: 6 + 6 + 9 + 9 \u003d 30 m

30 m - perimeter, it is divided for the length of one bar.

30 m / 6 m \u003d 5 pcs.

Total: for the construction of Mauerlat for building 6 × 9 m, it is necessary 5 bars 6 m each.

Calculating the amount of material for rafters and crate

The rafting system is the main support for roofing material, it protects it wind and snow.

Calculation of material for the construction of a house from a bar, which will be on the construction of the rafter is carried out by the formula:

1. The total load of snow and wind per square meter of the roof - it is calculated on the basis of SNiP 2.01.07-85 "load and exposure". For a slope with an angle of tilt 45◦, the length of the roof is 6.5 m and a rafted-length 3.5 m load will be 226.3 kg / sq. M.
2. The overall load is 5148 kg. We multiply 6.5 by 3.5 and we get 22.75 m - this is the surface area of \u200b\u200bone slope. Accordingly, 22.75 * 226.3 \u003d 5148 kg.
3. Now it is necessary to find out the length of all rafters and, therefore, how much it is necessary to purchase a bar for their facilities. For this, based on the fact that one mongon meter is able to withstand 100 kg of weight, divide 5148 per 100, as a result we get 51.48 m - this is the minimum length of the rafted.
4. The slope of the roof hangs over the wall of about 50 cm, accordingly, to buy wood in 4 m.
5. Calculate the number of pieces simply: 51.48 / 4 \u003d 12.87, and if more precisely 14, since they are located in pairs. That is, you need 7 pairs.

The instruction states that the distance between the rafyles is equal to the number that it turns out if we divide the length of the roof per unit less than the number of pairs of the rafter: 6.5 / 6 \u003d 1.08 m. The cross section of the blanks 100 * 150 mm or 150 * 150 mm.

The rafting system includes a wooden crate. For her, boards are used with a thickness of about 2.5 cm. They are located horizontally, that is, parallel to the skate.

The width of the board should not exceed 15 cm. There are two ways of laying, which will depend on the amount of the material acquired.

The first is solid styling, when the distance does not exceed 1-2 cm and discharged. Then the span can reach 10 or more centimeters. The more often the boards are, the stronger and the warmer design, but at the same time and more expensive.

Calculate the number easily. The length of the skate and board are measured. Further, the rode of the skate divide on the boarding board. It helps to know how much boards for one strip.

If the width is 15 cm, and the gap 5, then the number obtained by the result is divided by the length of the skate. Total turns out the number of blanks in pieces.

The calculation of the value of the construction of the house from the bar is a very painstaking occupation, it is necessary to take into account that everything must be purchased with a small marriage. Roofing is calculated based on the roof surface area. It does not take into account the natural holes - the place for the chimney pipe and the attic door, if such is laid in the project.

Number of blanks for the beam device

Overlapping from wooden beams is most in demand in low-rise construction. They have a relatively low cost, they are easy and quickly made, the tree is quite durable material, with a low weight. It does not have significant loads on the foundation.

For overlapping from the beams, only wood coniferous rocks is used, more often larch is the most durable and reliable material that can withstand considerable weight:

• resistant to temperature fluctuations;
• retains stable geometry;
• almost does not give a shrinkage.

It is better to choose a blank that were dried in steam chambers and has no more than 14% humidity. The aspect ratio should be 150 * 100 mm or 150 * 200 mm.

For the right design to produce the right calculation of materials for the construction of the house from the bar, it is necessary to guide the width of the span. The greater the span, the more often the beams are stacked and their number will increase. For the attic overlap, it is not necessary to put the blanks too close to each other.

Here is the table, following which it is easy to determine how many pieces will need:

This means that for a flight in 4 m I must buy 6 blanks for laying beams of overlaps, taking into account the step in 1 m. That is, 4 pieces will go to the closure of the span and 2 more on the edges, directly near the walls. The price depends on the length of the bar.

Stage Three: The amount of gender

Before you start calculations for buying a floorboard, you need to decide on its parameters.

• The most optimal are considered: Length 4, 4.5 and 6 m.
• Thickness is represented by such dimensions: 30 mm, 25 mm and 32 mm.
• Standard width is 100 mm and 105 mm.

If you want to make the floor from the whole boards, it is desirable to reduce the amount of waste.

The calculation of the material for the construction of the house from the bar is produced on the basis of the length and width of the area covered. And also how the board will be charged - along or across.

Calculations are quite simple. If you know the parameters of the blanks, you can determine the useful area, it is 5-7 mm less actual due to the tongue.

Most often manufacturers make boards at 6 m. It is necessary to take into account the possible amount of waste that cannot be avoided.

Calculations are made in this way:

1. a predetermined area of \u200b\u200bresidential premises is divided by the size of the square of one board, considering only useful - this is the amount required for laying;
2. when the room has other parameters other than 6 m, it is important to know the amount of the whole material. For this room width is divided into a working width of the floorboard.

Based on the information received, it's easy to find out in what about the amount will cost the construction of the house from the bar. It is also necessary to take into account the consumables: insulation, the material for the roof, additional fasteners. Their number depends on the project of the house, terrain and other factors.

Output

The video in this article will clearly help you understand these issues.

It does not matter whether you have found a decent construction company or decided to make a house from a bar with your own hands - at some stage you just need to calculate the number of lumber required for its construction. What do you need to know for this? First, how much and what bar is needed to the house. Secondly, how much about it in one cubic meter. And then you can spend the simplest calculation of the cost of building and even make an approximate estimate.

Calculate the amount (consumption) of the material

Immediately make a reservation that all the following calculations are approximate. More accurate material volumes can be determined based on a specific project. The lumber cube on the walls from the timber can be calculated as follows:

• calculate the perimeter of the house;
• multiply it to the height of the floor;
• the resulting value multiply on the thickness of the timber;
• as a result, we have the number of cubes for the construction of one floor.

If except the external walls are also implied by the presence of internal partitions (also from the bar), then they are additionally taken into account. If desired, the material can be calculated not only by volume, but also in pieces, dividing the total volume per piece.

Let us give a specific example: it is necessary to build a small one-storey house of 5 × 7 m with a simple attic and one partition. The ceiling height is 3 m. At the same time, the timber will be used with a cross section, for example, 150 × 150 mm, the frontton will also be laid out.

Our calculations will look like this:

• the perimeter of the house, taking into account the length of the partition: (5 + 7) × 2 + 5 \u003d 33 m;
• the volume of the walls of the first floor: 33 × 3 × 0.15 ≈ 15 cubic meters. m.;
• the cube of a bar on the frontton we consider something about half of the material required by two walls with a length of 5 m and a height of 3 m: 5 × 3 × 0.15 \u003d 2.25 cubic meters. m.

Total to the wall will leave about 17.25 cubic meters. m, or, taking into account 20% of the reserve, about 20 cubic meters. m. But it should be understood that we did not take into account, for example, the beams of overlapping from the glued timber (ordinary or profiled), as well as other design features. Therefore, you can still boldly add 5 cubes. As a result of such approximate calculations, it turns out that the construction will go about 25 cubes. (But window and doorways, on the contrary, will reduce the need for lumber.)

How many timber in Cuba

Simple calculations allow not only to calculate the cube on the house, but also to determine hardly the exact number of bars. Make it easy: it is enough to know the required volume of lumber and the volume of the piece product to divide one value to another. Here is the table in which the most common sizes of cross sections at a length of 6 meters.

Brous dimensions

Defined with them, it is necessary to proceed from economic feasibility. It is mostly about the thickness of the walls and thermal conductivity characteristics of the material. Consider this in two variations: summer (country) house and building for permanent residence.

Thickness and width

The width of the bar should worry the developer only if permanent accommodation is planned, and it is not always - because any wooden wall can be insulated with effective thermal insulation, thereby avoiding losses to the "Street Heating". For the cottage it is quite possible to use a cross section of 100 × 100 mm. Using the usual non-stroke material, it will still have to solve issues with facade facing and interior decoration, shattered, for the most part, with the problems of the result of the result. But for PMG it is better to use a profiled timber with a width of 150 mm. Warm walls in this case will still have to. As for thickness, everything is easier: the number of bars needed to build walls only depends on it. But, meanwhile, it affects the number of seams between the crowns. Summarizing the foregoing:

• the thickness and width of the bar for the country house practically does not matter (with seasonal accommodation in a warm course of the year);
• for permanent residence, you can choose a large width, but it will still have to warm the walls. And you can save on the cube by making a bet on high-quality insulation - it will be cheaper and more efficient in terms of cutting heat losses.

So, to build a truly warm house without insulation, the thickness of its walls for the Moscow region should be about half a meter. The same effect will be using a bar 150 × 150 and 10-15 cm of heat insulation.

We draw your attention to the fact that not all manufacturers and sellers of sawn timber are honest with their customers: often you can face the declared cross section. For example, a ram 150 × 200 in fact has a cross section of 140 × 190 or even less. Be sure to check the actual parameters before purchasing! It will help you not to get to hear, save money and nerves!

Estrase

Before you decide on the choice of builders, deal with monitoring offers. To determine the most economically appropriate option, ask different competing firms for their estimates for the selected typical or individual project, which includes all costs: and the cost of building materials, and the fee for the implementation of all types of construction work.

Normal companies offer such estimates for free. It is noteworthy that different firms the final sums on the same buildings may differ not only by 10-20%, but also several times. It is advisable to have in your hands the most detailed list of works and materials for the embodiment of your idea - just so you can avoid additional, unforeseen expenses along the way.

If desired, the estimate can be drawn up on its own: counting the consumption of materials, multiplying the results for average prices (in total it will be the costs of building materials) and the addition of approximately 50-100% of this amount on the payment of work. Such an approximate calculation can be used to analyze offers from relevant companies.
