How to calculate the cubic meter of timber on the house?

The tree at all times was 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 is worth buying.

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 the required amount of 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 required to calculate so that during the construction work does not have to buy an additional amount of timber. After all, it will be a shame if in the midst of construction work there is not enough board. Again, you have to run around the market or companies in search of the missing part, spend your money on delivery. Or after the construction is completed, you have to think about where to attach the remaining material.

How to calculate cubic bar

If you look, there’s nothing complicated about it. For example, take the following values.

When calculating, it turned out that 30 boards with a length of 6 meters are required, a thickness of 50 millimeters, a width of 200 millimeters. All data needs to be multiplied. To do this, all units must be converted into one measurement value - meter. It turns out that the width of the board is 0.20 meters, the thickness of the board is 0.05 meters. 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 needed, you can find out how many boards are in a cubic meter. We calculate how many pieces are in one cubic meter if the lumber is 200 millimeters wide, 50 millimeters thick, and 6 meters long. All values ​​must be divided. Volume / width / thickness / length = 1 / 0.20 / 0.05 / 6 = 16.666.

For a quick calculation, you can use the table. Before calculating the cubature of a beam, you need to find out what parameters it will have.

According to the table it is clear that in a cubic meter the number of timber units depends on the dimensions of length, thickness, width. Therefore, in one cubic meter, changing sizes, we get a different amount of timber.

How to calculate the cubic meter of timber 150x150 millimeters, if the length is not six, but three meters? To do this, multiply the width, thickness, length. It turns out 0.15 x 0.15 x 3 = 0.0675 cubic meters.

Subtleties in the calculation

To use your funds economically and rationally, you need to calculate the number of cubic meters as accurately as possible. But when buying, take a little in stock, about five to ten percent more, because the beam can be defective, it can be twisted at the time of work, and other unforeseen situations can also occur.

Whatever the volume of work, you always need to take different types of lumber. For building walls, one is suitable; on the rafter system, completely different ones are used. Therefore, you need to carefully plan the project for a house or bath. Using tables or formulas, you should calculate the quantity and the required dimensions.

How to independently calculate the cubature of a bar for a house

For example, consider the option of a small one-story summer cottage for summer living. It was decided to build a house six by six meters with a ceiling height of three meters and make one six-meter partition. We calculate the cubic capacity of a bar for a house with such parameters. If the house will be used only in the summer season, it is worth buying a beam with a section of 100 x 100 millimeters. When planning year-round living, it is necessary to make the walls of a thicker material, the width of which will be at least 150 millimeters.

Calculation of the required volume of timber per house:

• perimeter: (length + width) x 2 + partition = (6 + 6) x 2 + 6 = 30 meters;
• the volume of the walls of the house: (perimeter x beam thickness x wall height) = 30 x 0.1 x 3 = 9 cubic meters for a summer house. Or 30 x 0.15 x 3 = 13.5 cubic meters for a house with winter living;
• gables: (width x beam thickness x height) = 6 x 0.1 x 3 = 1.8 cubic meters will be required for a summer house. And 6 x 3 x 0.15 = 2.7 cubic meters for living in the house all year round.
• Add the resulting results and add to them 20% of the total, for stock. (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 meter of timber in a bath

Recently, the fashion for rest in the country has returned. Young families with children are increasingly acquiring garden plots. Many people wonder how to build with their own hands and how to calculate the amount of lumber in the bath. If you understand all the subtleties and moments, then there is nothing complicated.

The most popular bath size is 4 x 6 meters. Make better from natural timber. Starting construction, it is necessary to determine the exact amount of lumber. For the outer walls use bars with a size of 250 x 130 mm, on the internal partitions 130 x 95 mm. We calculate:

• The perimeter of the bath of this size is 5500 x 3500 millimeters.
• For each wall, 21 timber is required. 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. We translate in millimeters, it turns out 20,000.
• It is necessary to find the total length of the bars. For this, the number of bars x per length = 21 x 20,000 = 420 meters. We translate in millimeters, it turns out 420,000.
• Multiplying the resulting amount by the size of the beam, we get 420 x 250 x 130 = 13.65 cubic meters.

To calculate the required amount of timber on the partitions, use the same description with the only difference being that a different timber size of 95 x 130 millimeters is required. Cubes for partitions are also calculated. For internal walls, a smaller beam in thickness is used.

For large volumes

How to calculate the cubic meter of timber for a large house? In this case, lumber of different lengths, widths, thicknesses will be required. It will be easier to calculate not the volume of wood (dense), but to use the calculation of “folding 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 in piles, joining different sized beams so that their length is the same. When everything is sorted and evenly stacked in a stack, measure the dimensions (width, length, height). The results are multiplied. Now - how to find out the cubature of a dense beam. For this, the obtained result of the folding cubic should be multiplied by a special coefficient.

Calculation of crowns

In order to find out the required number of crowns in a log house, it is necessary to divide the height of the house by the height of the beam (working). We calculate the cubic meter of timber on 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. We round, it turns out 19 crowns are necessary for a given height. The length of one crown is 9 meters, it is required to calculate how many meters are running in one crown, along with cuts. We will calculate how many linear meters in the lower crown. To do this, you need to fold all sides 9 + 9 + 9 + 9 + 9 = 45 meters. To calculate the total number of running meters in this house, you need to multiply the length of one crown by the number of crowns. It turns out, 19 x 45 = 855 linear meters. Given the zero crown, you need to add it to the total number so that there is a shift in the row. 2.5 x 9 = 22.5 meters linear halves of the crown. 855 + 22.5 = 877.5 m. P., It is with door and window openings.

How to correctly calculate the cubature of a profiled beam? 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 for a house measuring 9 x 9 meters. Be sure to take into account when calculating the loss of timber about 7% of the total, for trimming and sawing.

The advantages of a wooden house built using timber

• There is no need for interior and exterior decoration of the house. The walls are flat and smooth. They look beautiful.
