Calculate laminated timber for a house using a calculator. Preliminary calculation of materials for building a house made of timber. How much material is needed to build a log house?
Wood has always been the most popular material for the construction of houses and baths. Nowadays, the demand for wood remains high. In order not to spend extra money, you need to correctly calculate how much timber it is worth purchasing.
What are the difficulties in calculating the volume of timber?
At the time of preparation, before the start of construction, it is not easy to calculate required amount timber. The volume is calculated in cubic meters, it is at this point that difficulties begin. It is difficult for the buyer to understand the correct calculation of cubic capacity. It is necessary to calculate so that during construction work it is not necessary to purchase additional quantities of timber. After all, it will be a shame if, in the midst of construction work, there are not enough boards. Again you will have to run around the market or companies in search of the missing part, and spend your money on delivery. Or, after construction is completed, you will have to think about where to place the remaining material.
timber
If you look at it, there is nothing complicated about it. Let's take the following values as an example.
When calculating, it turned out that 30 boards were required, 6 meters long, 50 millimeters thick, and 200 millimeters wide. All data needs to be multiplied. To do this, all units must be converted into one measurement unit - meter. It turns out that the width of the board is 0.20 meters, the thickness of the board is 0.05 meters. We multiply: width x length x thickness x quantity = 0.20 x 6 x 0.05 x 30 = 1.8 cubic meters.
If the buyer knows how many cubes of lumber are required, he can find out how many boards are contained in a cubic meter. Let's calculate how many pieces are in one cubic meter if the lumber is 200 millimeters wide, 50 millimeters thick, and 6 meters long. All quantities must be divided. Volume/width/thickness/length=1/0.20/0.05/6=16.666.
To quickly calculate, you can use the table. Before calculating the cubic capacity of the timber, you need to find out what parameters it will have.
Beam width (mm) | Beam thickness (mm) | Beam length (m) | Quantity cubic meters in one beam | Number of timber in one cubic meter (pcs) |
From the table it is clear that in a cubic meter the number of units of timber depends on the dimensions of length, thickness, width. Therefore, in one cubic meter, changing the dimensions, we get different quantities timber.
Subtleties in calculation
In order to use your funds economically and rationally, you need to calculate the number of cubic meters as accurately as possible. But when purchasing, do not take much in reserve, about five to ten percent more, because the timber may turn out to be defective, during operation it may be twisted, and other unforeseen situations may also occur.
No matter the volume of work, you always need to take different ones. For the construction of walls, only one is suitable, on rafter system completely different ones are used. Therefore, you need to carefully plan the design of your house or bathhouse. Using tables or a formula, you should calculate the quantity and required dimensions.
How to independently calculate the cubic capacity of timber for a house
For example, consider the option of a small country house one-story house for summer stay. It was decided to build a house six by six meters with a ceiling height of three meters and make one six-meter partition. Let's calculate the cubic capacity of timber for a house with these parameters. If the house will be used only during the summer season, it is worth purchasing timber with a cross-section of 100 x 100 millimeters. When planning year-round living, it is necessary to make walls from thicker material, the width of which will be at least 150 millimeters.
Calculation of the required volume of timber for a house:
- perimeter: (length + width) x 2 + partition = (6 + 6) x 2 + 6 = 30 meters;
- volume of the walls of the house: (perimeter x timber thickness x wall height) = 30 x 0.1 x 3 = 9 cubic meters for summer house. Or 30 x 0.15 x 3 = 13.5 cubic meters for a house with winter living;
- gables: (width x timber thickness x height) = 6 x 0.1 x 3 = 1.8 cubes required for a summer house. And 6 x 3 x 0.15 = 2.7 cubic meters for living in a house all year round.
- Add up the resulting results and add to them 20% of the total volume, for reserve. (9 + 1.8) + 20% = 10.8 + 2.16 = 12.92 cubic meters and (13.5 + 2.7) + 20% = 16.2 + 3.24 = 19.44 meters cubic.
How to calculate the cubic capacity of timber for a bathhouse
Recently, the fashion for vacationing outside the city has returned. Young families with children are increasingly purchasing garden plots. Many people wonder how to build it with their own hands and how to calculate the amount of lumber for a bathhouse. If you understand all the subtleties and moments, then there is nothing complicated.
The most popular 4 x 6 meters. Make the best of natural timber. When starting construction, you need to decide on the exact amount of lumber. For external walls use 250 x 130 mm, for internal partitions 130 x 95 mm. Let's calculate:
- Bathhouse perimeter given size it turns out 5500 x 3500 millimeters.
- Each wall requires 21 timber. This is calculated taking into account the size of the floor and the thickness of the ceiling.
- The log house has four walls. It turns out (6 x 2) + (4 x 2) = 20 meters. Converting to millimeters, it turns out to be 20,000.
- We need to find the total length of the beams. For this, the number of beams x length = 21 x 20000 = 420 meters. Converting to millimeters, it turns out 420000.
- Multiplying the resulting amount by the size of the timber, we get 420 x 250 x 130 = 13.65 cubic meters.
To calculate the required amount of timber for the partitions, use the same description with the only difference being that a different size of timber is required, measuring 95 x 130 millimeters. The cubic capacity for partitions is also calculated. For interior walls a beam of smaller thickness is used.
For large volumes
How to calculate the cubic capacity of timber for big house? In this case, lumber of different lengths, widths, and thicknesses will be required. It will be easier to calculate not the volume of wood (dense), but to use the calculation of the “folded cubic meter”. In the first case, the results are used when measuring each beam separately, without voids. In the second case, all the lumber is stacked, joining the beams together different sizes so that they are the same length. When everything is sorted and evenly stacked, measure the dimensions (width, length, height). The results obtained are multiplied. Now - how to find out the cubic capacity of a dense beam. To do this, the resulting result of the folded cubic capacity should be multiplied by a special coefficient.
Calculation of crowns
In order to find out the required number of crowns in a log house, you need to divide the height of the house by the height of the beam (working). Let's calculate the cubic capacity of the timber for a house measuring 9 x 9 meters with one cut. For example, we use a beam profiled 140 x 190 millimeters; we need to calculate the number of crowns at a height of 2.5 meters.
Calculation: 2500/130 = 19.23. Rounding up, it turns out that 19 crowns are needed for this height. The length of one crown is 9 meters; you need to calculate how many linear meters there are in one crown, including cuttings. Let's calculate how many linear meters are in the lower crown. To do this, you need to add up all sides 9 + 9 + 9 + 9 + 9 = 45 meters. To calculate the total number linear meters in a given house, you need to multiply the length of one crown by the number of crowns. It turns out, 19 x 45 = 855 linear meters. Considering the zero crown, you need to add it to the total quantity so that there is a row offset. 2.5 x 9 = 22.5 linear meters of crown halves. 855 + 22.5 = 877.5 m.p., this includes door and window openings.
How to correctly calculate the cubic capacity of profiled timber? To do this, multiply the resulting length of the crowns by the height of the beam and multiply by the thickness of the profiled beam = 877.5 x 140 x 190 = 23.34 cubic meters will be required for a house measuring 9 x 9 meters. When calculating the loss of timber, it is imperative to take into account approximately 7% of the total amount for trimming and sawing.
Advantages of a wooden house built using timber
- No need for internal and exterior decoration Houses. The walls are even and smooth. They look beautiful.
- Moisture does not penetrate the seams located between the crowns. Moisture does not collect on the walls and rot does not appear.
- After a while, after the log house has shrinked, there is no need to caulk.
- The timber has a tight connection with a lock, which protects against blowing.
- Almost no cracks appear and are not deformed during shrinkage.
- Natural material, environmentally friendly.
- Does not require long assembly, assembles quickly, like a construction set.
- The houses have a beautiful aesthetic appearance.
- The house is easy to care for; there is practically no dust collecting on the walls.
- Possibility to paint the house any color.
Before starting to build a house made of timber, many consumers ask themselves: how much timber is needed for the construction of the planned structure. To answer this question you can go two ways:
- Use the beam calculation calculator;
- Read the article below about calculation of the amount of timber which will be needed to build a house.
And if everything is more or less clear with a calculator, then doing it yourself is much more difficult. Let's look into this issue.
Factors influencing the amount of timber required to build a house.
The main thing to consider when calculating the amount of timber per house is:
- What type of timber will be used in construction;
- How much timber do we need?
- How many units of timber are in 1 cubic meter;
- Features of the project of a house made of timber or a cottage.
Calculation of construction timber in cubic meters.
And so, how calculate the amount of timber in 1 cubic meter simple method? It should be noted that the example below is not exact. To make a more accurate calculation, you need to have a project of the future house.
To calculate the amount of timber in 1 m 3 you need:
- Calculate the perimeter of the building;
- Multiply the perimeter by the height;
- The product of the perimeter and height must be multiplied by the thickness of the product.
For our case, the formula will look like this: V = h*b*l = 0.15 * 0.15 *6 = 0.135 m3,
- h - beam height;
- b- width;
- l- length.
Let's find out how many units of lumber are in 1 cube as follows: 1/0.135 = 7.41 pieces.
After carrying out all the calculations described above, we will obtain the result of the number of cubes of timber required to construct the building.
To calculate timber, which will be needed for finishing the interior walls, we use a similar method. let's consider specific example, how to calculate the amount of timber for a bathhouse 5 * 10 meters, 3 meters high.
Let us conditionally determine that during construction the size 150 * 150 mm will be used.
- (5 m - width + 10 m length) × 2 = 30 m - perimeter of the building.
- 30 perimeter × 3 height = 90 m 2 - wall area.
- 90 area × 0.15 material thickness = 13.5 m 3 - needed to build a box from a 5 × 10 beam 3 m high.
Like this in a simple way we calculated the amount of timber for the walls, which is 13.5 m3. But, you need to take into account that due to the presence of window and doorways, the amount of material used will be less than calculated.
Often craftsmen do not take this point into account; it is believed that it would be even better to add about 20% in reserve, in the end we will get: 13.5 + 20% = 16.2 m 3 timber is needed for a building 5 * 10 m.
Features of timber that must be taken into account when calculating.
When building a house from timber, the first step is to lay the crown, which should be slightly thicker than the main beam. The first crown is made of thicker timber; later the weight of the whole house will put pressure on it, so it is additionally recommended to treat it with machine oil or an antiseptic.
In the calculation described above, this nuance was not taken into account; it must be calculated separately.
Calculation of timber in units.
After you have calculated the amount of timber in m3, you can easily find out how much timber will be needed in units (pieces).
Consider a table of common sizes of this product 6m long:
Table of the amount of timber in 1 m 3 for calculating timber for a house.
|
Section * timber length |
Volume 1 piece, m3. |
Quantity of timber in 1 m3, pcs. |
|---|---|---|
In the above example, where we indicated the cubic capacity of the timber for the bathhouse, we will carry out further calculations of the materials in pieces.
In order to calculate the amount of material per house in pieces, we carry out the following calculation; for this, the amount of 13.5 m3 must be divided by the cubic volume of the timber used, in our case it is equal, based on the table, to 0.135 m3: 13.5: 0.135 = 100 pieces.
If you correctly calculate the amount of timber in pieces, then when purchasing timber you will be able to control whether all the material is shipped to you by the seller.
Thickness and height of the timber.
The material can have different thickness and height, the following are the main dimensions:
- 100*100 mm.
- 100*150 mm.
- 150*150 mm.
- 150*200 mm.
- 200*200 mm.
If everything is clear with height, the higher the beam, the fewer inter-crown seams, the faster the production construction works, and naturally, the number of pieces of timber for building a house decreases. But the width in this case is more important, especially when building for everything seasonal residence.
Attention: Sometimes timber manufacturers indicate the dimensions of the timber, which may differ from the real ones; for example, a timber of 150x150 mm actually has a size of 140x140 mm.
The consequences of purchasing such a beam will be very disastrous, if for a height of 3 meters you will need 20 pieces of timber measuring 150x150 mm, then for a size of 140x140 mm - 21 pieces and a half, and this is one and a half crown rows.
If you plan to live in the house all year round, it is recommended to use 200 mm thick timber. It is also necessary to take care of the insulation of timber walls, the best option will be polystyrene or mineral wool 10 cm thick.
When constructing a bathhouse, it is advisable to use a material thickness of 150 mm; it is quite sufficient for short-term temperature maintenance. Well, if you decide to build country house for summer holidays, then in this case walls made of 100x100 mm timber will be just right.
A wooden house has a special appeal. In addition to its superior aesthetics, it has many other advantages, which explains the growing popularity of this type of housing. Preliminarycalculation of a house made of timber will help you accurately determine upcoming expenses and assess your financial capabilities for such a building.

Types of materials for wooden buildings
Before calculating a wooden building, you need to decide what material to choose for it. Currently, developers are offered the following lumber for this purpose:
- regular (sawn) and profiled timber made of solid wood;
- regular and profiled laminated wood timber;
- calibrated (rounded) log.
These are the main lumber used in the construction of wooden buildings, but profiled laminated veneer lumber is considered the best among them. Its advantages are:
- minimum residual moisture in the range of 10–18%, virtually eliminating shrinkage and deformation of wood;
- ideal shape and precise linear dimensions of the material, which extremely simplifies and facilitates the assembly of the building;
- increased strength compared to similar solid wood timber;
- no need for additional sealing of the seams between the beams.
These characteristics do not greatly affect the total amount of material for the construction of the building - except that the consumption of timber will be slightly lower due to reduced losses due to waste.
Anyway preliminary calculation of a house made of timber at the building design stage will allow you to optimize the costs of future construction in terms of quantity and cost of material. In order to correctly calculate the consumption of timber and logs at the first stage, it is necessary to carefully prepare the building design and carry out its detailing, taking into account the layout, dimensions, locations for window and door openings.
General principles for calculating lumber for wooden houses
To calculate the total amount of lumber for a wooden building, you need to divide this procedure into three stages - according to the number of main structural parts of any building. Calculation of a house made of timber is made taking into account the following elements:
- walls and partitions;
- floors;
- rafter frame.
For each of the named parts of the building, calculations are made, taking into account the purpose of each element. For example, an outwardly similar wall and an internal partition are assembled from timber different sections, therefore, the amount of material for structures of the same dimensions can vary by more than twice.
Calculation of materials for walls and partitions
Walls and partitions made of timber or logs form the frame of a house. These are the main load-bearing structures of the building, and the walls are also responsible for its thermal insulation. You can calculate the amount of lumber for walls and partitions using the following algorithm:
1. The walls are measured along the outer perimeter and height of the building. Minimum size beam sections for home permanent residence is at least 150x150 mm. In this case, the width of the beam for the first (lower) crown should be greater than for subsequent rows.
2. The volume of material in cubic meters is converted into pieces based on the overall size of the timber. The resulting amount is rounded to big side up to a whole number.
3. The volume occupied by window and door openings is subtracted from the total amount of material.
4. For partitions (partitions) and houses for seasonal residence, timber with a cross-section of 100x100 mm is quite sufficient.
Carrying out preliminary calculation of a house made of timber, start with optimal thickness walls – this is 200–250 mm. This value guarantees proper thermal insulation, and the walls will not need additional insulation.
If you choose a calibrated log for a log house, then its diameter should be at least 220–260 mm. When calculating a wooden bathhouse, the normal thickness of walls made of timber is considered to be in the range of 125–150 mm or made of logs with a diameter of 200–240 mm.
Developers who do not have sufficient experience may need help to draw up a building design and calculate the amount of materials. The easiest way to find it is on the Internet. Here you can buy a ready-made project, get help in the form of advice on forums from people who have already built a log house with their own hands. However, the scope of work on building a wooden house is not limited to the construction of walls.
Calculation of materials for floors
Ceiling and basement floors form the volume of premises (rooms). Their basis is wooden beams, which rest on the foundation and load-bearing walls. To calculate the required amount of material for floors, you should adhere to the following requirements:
- the step width between adjacent beams should not exceed one meter;
- the optimal cross-sectional size of the beams is 100x150 mm;
- the outer beams must be adjacent to the walls along their entire length;
- the number of beams, depending on the orientation of their installation, is determined as follows: the length or width of the building must be divided by the step size indicated in the project and subtract one unit.
To perform correctly calculation of a house made of timber from the point of view of the strength of the floors, the operational load of the building should be known or predicted. This way it will be possible not to lay down excess strength characteristics beams, saving a decent amount on this.
Beams in a timber house Where calculations are required load-bearing structures, it is best to take the help of specialists. Implementation cannot be avoided without this individual project. The costs of design services are not so significant that we would not consider this option for preparing the construction of our own housing.
Floors in a house made of timber Calculation of materials for the rafter frame
roof arrangement in a timber house Unlike walls and ceilings, the rafter frame has a volumetric configuration. Therefore, it is much more difficult to calculate. In addition, it consists of many parts of different sizes, and other materials are used in it besides timber. The roofing design must take into account the following factors:
- operational and wind loads;
- roof type and slope;
- view roofing material And so on.
Carrying out preliminary calculation of a house made of timber At the roof design stage, we must not forget that when constructing a roof, beams of different sections are necessarily used. The step width between the rafters should not exceed 70 cm. Largest section have a ridge beam and mauerlats. The rafter frame must ensure the presence of roof overhangs, etc.
In this case, you will need the help of specialists more than ever. For example, you can buy a ready-made house project made of timber or logs to adapt it to suit your needs. The main advantage of such a solution is that it eliminates the risk of errors, which can cost much more than the fee for the service received.
It is also necessary to include the sheathing of the rafter frame in the calculation of the roof. It can be solid or lattice depending on the chosen roofing material. Since window and door blocks most often they buy ready-made, on this preliminary calculation of a house made of timber can be considered completed. All you have to do is get your rough notes in order so you can move on to purchasing the necessary materials.
In order for your project to take on its proper form, you must complete calculation of a house made of timber finalization of its results. In the language of professionals, this is called drawing up a material specification. This document allows you to control the amount of lumber in the assortment and the total cost of purchasing it. The specification is drawn up in the following order:
- the volume of materials in cubic meters is summarized according to basic parameters, such as the cross-section and types of timber, width, thickness and length of the boards;
- lumber is converted into pieces, which greatly simplifies the purchasing process and makes it easy to control their quantity and range.
We would like to note that the typical sizes of timber, logs, and boards are multiples. You must take this circumstance into account when drawing up a project. Otherwise, significant waste losses are inevitable. In other words, the dimensions of the log house should be measured in numbers of the same order as standard materials. All the information necessary for this can be found in GOST 8486-86, GOST 24454-80 and others regulatory documents woodworking
Final stage calculating a house made of timber with the preparation of material specifications for the quantity and cost of lumber will provide you with indispensable assistance in assessing your own capabilities. At this stage, you can still make changes to the project: for example, make it cheaper or, conversely, use higher quality and more expensive materials.
Basic properties of wood: useful information
Carrying out calculation of a house made of timber, the main characteristics of wood should be taken into account. This will ensure a rational choice of materials and will allow you to perform a number of other important calculations (for example, when laying the foundation of a house). Among the main properties and characteristics of lumber are:
- residual moisture: it is not recommended to use wood with a moisture content above 23% in construction;
- density - this parameter directly affects the strength of the material and the weight of the building;
- resistance to moisture, rot, insects that harm spruce trees and other external factors.
Based on the combination of all its features, laminated veneer lumber is best suited for walls. It has the lowest possible residual moisture, and, thanks to its multi-layer structure, is superior in strength to analogues made from solid wood of any species. In addition, laminated timber is usually treated with antiseptics and fire retardants.
For walls and partitions we recommend using profiled timber. It is significantly more expensive, but these costs will be fully compensated by reducing work time, finishing costs, insulation and other costs that are inevitable when using less quality materials. Now you can safely start construction.
About construction country house many people think, but most put it off until tomorrow due to not knowing how to calculate the amount of timber per house. Why? Yes, because the counting process itself is not free, and no one wants to pay for something that may not be realized.
Let's try to understand how to correctly calculate the amount of this product for construction yourself.
Product calculation for building construction
Factors that influence the numbers
The main thing to consider when calculating the amount of material per house is:
- what type of timber will be used in construction;
- how much of it do we need;
- how many pieces in 1 cubic meter;
- what is .
Calculation of lumber in cubic meters
Let's look at how to calculate the amount of timber in a cube in the simplest way; one might say, this is the basic principle of calculations. It should be noted that the example given is not exact. To spend more exact numbers, you need to have a project for your future home.
So, pay attention to the instructions:
- Calculate the perimeter of the building.
- Multiply the perimeter by the height.
- Multiply the result by the thickness of the product.
- As a result, the result was the number of cubes of timber required to construct the building.
To calculate the product for interior walls, we use the same method. If desired, you can calculate not only the cubic capacity of the material, but also its quantity in pieces. Let's consider separate example, how to calculate the amount of timber for a bathhouse 3 m by 5 m with a height of 3 m.
Let's agree that during construction a size of 150 by 150 mm will be used.
Instructions:
- (3 width + 5 length) × 2 = 30 m – perimeter of the building.
- 30 perimeter × 3 height = 90 sq.m – wall area.
- 90 area × 0.15 material thickness = 13.5 cubic meters - needed to build a box from 3x5 timber 3m high.
Thus, the amount of timber for the walls is 13.5 cubic meters. But, it should be noted that window and door openings will reduce the amount of material used.
In most cases, masters do not take into account this moment, it is believed that it would be even better to add about 20% to the reserve, in the end we will get:
- 13.5 + 20% = 16.2 cubic meters will be required for this type of building.
Note!
When building a house from timber, the first crown should be slightly thicker than the main product used to build the walls.
It is not taken into account in our calculation; it must be calculated separately.
The first crown is laid from a thicker one, since in the future the weight of the entire house will fall on it; it is additionally recommended to treat it with machine oil or an antiseptic.
Calculation in pieces
By calculating how many cubes of lumber to build a house, you can easily find out how many pieces of timber you will need. This is the first thing you need when purchasing. Knowing exact amount pieces, you will protect yourself from possible fraud on the part of the selling company.
Consider a table of common sizes of this 6m long product:
| 100x100 | 1 PC. — 0.06 cube | 16.67 pcs. cubed |
| 100x150 | 1 PC. — 0.09 cube | 11.11 pcs. cubed |
| 150x150 | 1 PC. — 0.135 cube | 7.41 pcs. cubed |
| 100x200 | 1 PC. — 0.12 cube | 8.33 pcs. cubed |
| 150x200 | 1 PC. — 0.18 cube | 5.56 pcs. cubed |
| 200x200 | 1 PC. - 0.24 cubes | 4.17 pcs. cubed |
In the above example, where we indicated the cubic capacity of the timber for the bathhouse, we will carry out further calculations of the materials in pieces.
So, to find out the amount of material per house in pieces, we carry out the following calculation, for this we divide the amount of 13.5 cubic meters that is needed to build a bathhouse by the cubic volume of the timber used, in our case it is equal, based on the table, 0.135 cubic meters :
- 13.5: 0.135 = 100 pcs
Knowing correct amount products in pieces, you will not have to run around with a tape measure when purchasing and calculate the volume to find out whether you received the material correctly according to the invoice, you will only need to count the product individually.
The role of height and material thickness
Before calculating the quantity, you need to decide on the choice of thickness and height of the product.
The material can have different thicknesses and heights; here are the main dimensions:
- 100x100 mm.
- 100x150 mm.
- 150x150 mm.
- 150x200 mm.
- 200x200 mm.
With height, everything is simple, the higher the timber, the fewer crown joints - construction work goes faster, and naturally, the number of pieces of material for building a house decreases. But width is more important, especially when building for all-season living.
Note!
Not all lumber manufacturers are honest with the buyer; sometimes it happens that a 150x150 mm timber actually has a size of 140x140 mm.
It’s not difficult to guess what this will lead to, if for a height of 3 meters you will need 20 pieces of timber measuring 150x150 mm, then for a size of 140x140 mm - 21 pieces and a half, and that’s one and a half crown rows.
When planning year-round accommodation It is recommended to use timber with a thickness of 200 mm in the house. Such walls need to be insulated, but for our climate, something like polystyrene foam or mineral wool 10 cm thick is enough.
When building a bathhouse, it is recommended to use a material thickness of 150 mm; it is quite sufficient for short-term temperature maintenance. Well, if you decide to build a country house for a summer holiday, then in this case, walls made of 100x100 mm timber will be just right.
Advice!
During construction wooden house, in which it is not planned to live all year round, the thickness of the timber is not important.
After all, such a building is needed only for short-term use and mainly in the spring and autumn.
Pay attention!
Despite the large thickness of the product, you will still have to insulate the walls.
After all, in order for the house to fully fulfill its thermal insulation properties The thickness of the walls should be about 50 cm.
Why do you need a house project?
When calculating the material for building a house important role plays the project of the house itself. After all, only in finished project you can see not only appearance buildings, but also internal layout walls and elements that require additional calculation of the required material.
You can get a wooden house project in different ways:
- do it yourself;
- order from a specialist;
- buy a ready-made project;
- buy online;
- find on the Internet.
It is possible to make a house project with your own hands, but it is difficult, as you need to have special knowledge. And the point here is not only to draw future home, you need to take into account the specifics of climate, soil, air humidity and other points.
Most correct solution– order a project from a specialist, the price for such services is not cheap, but this is the most the best option, the specialist will take into account all your wishes and possibilities of the area. This will protect you from many possible troubles, and will also have someone to contact if problems arise.
Advice!
Do not buy projects on the Internet from unverified persons; most often they sell those projects that are posted on the Internet for public use.
Conclusion
By making the correct calculations, you will ensure light construction. There will be no need to think later about where to put the extra products or, worse, to suspend construction due to their shortage.
If you still have any questions, watch the video in this article, you will not only learn how to calculate timber on a calculator, but also be able to calculate approximate cost future home. You will definitely have no doubts about your ability to calculate the material yourself.
A log house is relevant, but not always convenient, since the walls need to be leveled with cladding; a wooden profile is much more practical, so sometimes it’s better calculate the amount of timber per house.
What do you need to know to calculate the amount of timber for a house?
– is this a little or a lot, and how many crowns of the house will this amount of timber be enough for? In fact, this is not such a large number of wood processing industry products. In particular, six-meter beams with a width and height of sides of 200 millimeters each will amount to only 4.17 pieces, or, since sellers like to round down, only 4 units. True, if you need more than 10 cubic meters, such rounding can play a cruel joke, and you will be missing one or even two lumber that you need so much. Therefore, you need to calculate the amount of timber per house as accurately as possible.
To begin with, determine the dimensions of the future building, that is, the length and height of the walls, the area of window and door openings, the step frequency of the crossbars (hardly in wooden house you will fill a monolithic concrete slab). You will also need to take into account the height rafter legs, and if the pediments are made in the same style as the building, then their geometry. In other words, immediately figure out where you will use the timber and include all the nuances in the calculations. Also immediately consider the options of using profiled, glued or unplaned beams; the latter are cheaper, but will decrease somewhat in size after processing on site.
Concerning overall dimensions, then from existing options with a section of 100x100, 150x100, 120x120, 140x140, 150x150, 200x150, 180x180 and 200x200 centimeters is usually selected golden mean. Dimensions 150x150 fully meet the requirements for timber, both in terms of thermal conductivity and ease of assembly. Reducing the dimensions will lead to an increase in the amount of materials, and therefore to greater labor costs, even if the volume in cubes is the same. An increase in size will mean an increase in the cost of the timber and its weight.
Let's use the timber calculator in practice
Since rarely does anyone buy (and sell) lumber individually, when tens or hundreds of units of one type or another are required, we need to determine how many cubes of wood we need to purchase. To do this, you need to know the dimensions of the house, and since they are reflected in the plan, it is enough to include them in the timber calculator. Let's say a small one is being built country cottage 6x5 meters, with a ceiling height of 3 meters. It is best to buy an appropriate wooden profile, six meters long. Knowing the height of the wall, we divide it by the cross-sectional side of the lumber we have chosen. Since we previously settled on dimensions of 150x150 centimeters, we get 3/0.15 = 20 beams, which will make up the wall of the building.
It must be said that insulation is usually laid between the crowns, which should increase the height, but shrinkage wooden profile compensates for this error in our calculation. We add a plinth crown, which gives 21 beams, and then we calculate how many similar woodworking products will be produced in the entire building. To do this, we multiply the result we obtained earlier by 4 (by the number of walls). However, it is unlikely that there will be one room in the house, so a fifth wall immediately appears, an internal one, which can also be permanent, taking into account a minimum span of 5 meters. So, we multiply by 5. As a result, it turns out that 105 beams are needed to build a house. Too much? Let's see how you can save money.
Let us remember that the premises must have windows and doors, which mean the presence of significant openings. Let's say the entrance from the street is planned in a five-meter facade, exactly in the middle, and it will be exactly a meter wide. Since the crowns here are one meter shorter than the actual length of the beam, it turns out that we need 2-meter sections to form the doorway. Then from every two beams you will get exactly three crowns on this side. If interior door between the rooms will be on the edge, four-meter profiles will be needed there, the trimmings of which can also be used to create an external opening. Thus, for every three crowns of this wall we save one beam until the lintel is laid over the entrance.
Sometimes the ends of the lumber from which the house is built are sawn in the form of tenons, in door and window openings rest against the groove of the riser, the width of which is equal to the thickness of the wall.
If the height of the door is 2.1 meters, we will have 14 crowns, that is, the remainder will be 4 six-meter wooden profiles. In the same way, you can save on windows by correctly arranging them in the overall layout of the premises, and then, quite possibly, you will no longer need 105, but some 98 beams. Use those that you can win for attic floor and fastening the rafters, since such material will not work as interfloor joists, you need a profile whose sides are in a ratio of 7:5, with the height being the first in proportion.
How to calculate a cube of timber for a house - the simplest method
We have already obtained the result necessary for further calculations, namely the number of wooden profiles that will be needed for construction. Now you need to determine how to calculate a cube of timber for a house, and how much lumber is needed. Knowing the dimensions of the woodworking product from which the crowns are knitted, it is not difficult to obtain its volume. In our case, this will be the formula V = h . b . l = 0.15 . 0.15 . 6 = 0.135 cubic meters, here h– beam height, b– width, and l- length. Let's find out how many units of lumber are in 1 cube as follows: 1/0.135 = 7.41 pieces. They may not sell that much, sellers don’t like to cut six-meter beams, so they can reduce it to 7, or they will have to pay extra up to 8 beams.
But, since we need a lot of materials, and we know that the number of profiles will be integer, we calculate how many cubic meters of wooden profile will have to be transported to the site. We multiply the total quantity by the volume of one, let’s say we managed to save money and actually got 98 bars, then we get 0.135 . 98 = 13.23 cubes. However, all these calculations can be eliminated if you use the following table.
The amount of timber in 1 cubic meter. to calculate timber for a house
[Section]x[length] of beam, | Volume 1 pc., | The amount of timber in 1 m 3, |
|---|---|---|
You can take a simpler route. To do this, we calculate the perimeter of the house, multiply it by the height of the walls and get the total area of the outer surface of the building, excluding the roof. Next, we subtract the area of window and door openings if high accuracy is needed, or leave it as is if the savings are not critical. The calculation is completed by multiplying by the thickness of the timber. In our case, the short formula will look like this: V = P. H. b = 27. 3. 0.15 = 12.15 cubic meters excluding the base crown and based on the fact that 3 walls are 5 meters each. As you can see, this calculation is less accurate, since the length of all lumber is 6 meters, and we took many of them as five meters.
