How to calculate the cubic capacity of timber - tips on

As practice has shown, most of the novice builders cannot correctly calculate the required amount of construction material, as a result of which additional costs are incurred (the price of wood is quite high, so any extra costs can seriously affect your finances).

In fact, the cubic capacity of a bar is calculated quite simply, and it does not require any specific knowledge and skills.

If you refer to the special table for calculating the cubic capacity of the produced lumber (see photo), (according to which you can easily calculate the number of unedged boards, edged boards, bars, slats, floor boards or lining boards), you can easily calculate.

If the table was not at hand, then you can make the usual mathematical manipulations:

• For example, you roughly calculated that you would need 20 boards 6 meters long, 15 cm wide, 40 mm thick;
• So, in order to understand how much it will be in cubes, we need to multiply all the quantities on each other (0.04 x 0.15 x 6 x 20 9 is the number of the board - in the end we get 0.72 m?);
• The amount received is the required amount of material that you need to work. Now we find out how many similar boards are contained in one cube;
• To do this, you will need 1 / 0.15 / 0.04 / 6 = 27.777 - in the end it turns out that in 1 m? is about 27-28 boards.

Calculate the amount of timber

As practice has shown, it is much easier to build from a bar than from a log. At the exit we get a geometrically flat building on all sides. But in order to build such a house or cottage from a bar, you need to calculate the required amount of material.

In general, everything depends directly on the quality of the timber and the installation of the building itself. Due to the fact that the manufacturer often sells poor-quality material (when unpacking, some products may simply not be suitable for installation due to poor quality, so it is recommended to buy products with a margin that may be useful in case of unforeseen circumstances).

So, the calculation can be made as follows: the length of the walls of the building is multiplied by the height and multiplied by the thickness of the purchased timber. The resulting number will be the cubic capacity that is required for construction.

Attention! It should be remembered that this type of calculation will not give you exact figures, as often, when you buy, you come across poor-quality building material.

If you are still worried about the question - how to count the cubic capacity of a bar, you can resort to another method. To do this, you need to calculate the entire length of the walls around the perimeter of the house and divided by the length of the beam. As a result, we get the number of products that will be required for the construction of one crown. Now, it is necessary to measure the height of the future building and divide this value by the thickness of the timber used. (See also the article How to choose projects of houses from a bar to take everything into account)

The final step - the resulting number is multiplied by the number of load-bearing walls and multiplied by the number, which means the amount of timber required for one crown. The result will be the necessary number of products.

Attention! If your house will have load-bearing walls not only around the entire perimeter of the building, but also additional (for example, which separate the house and the veranda), then the length of these partitions should be taken into account when counting.

Attention! Even if you managed to calculate the exact amount of building material needed, you should buy 20-25% more wood, so to speak, in reserve.

Also, you should take into account the moment that after the erection of walls and partitions, you will need a bar to install the truss structure. That is why experts recommend making calculations with their own hands in order to avoid additional costs for the delivery of additional material.

Calculation of timber for building a house, depending on its proportions

Often, small wholesale sellers (or retailers) offer you to purchase a 50x100 bar or the same 20x40 rail with the price per linear meter, or even offer their goods by the piece.

Attention! The quantity of a bar in one running meter directly depends on the width and thickness of the product itself.

How to calculate the cubic capacity of the timber in this case?

Let's look at everything with an example:

• In the event that you buy a product 150x180, it turns out that its thickness will be 150 mm and its width 180 mm;
• Now it is necessary to multiply 1 m. on the width and thickness of the timber - is obtained 0,027 m? in one running meter;
• Now, if we want to find out how many cubes are in a material of this cross section of 6 meters in length, then the result should be multiplied by 6;
• It turns out that 6x0.15x0.18 = 0.162 m ?. From the obtained result it becomes clear that approximately 6 products will be contained in one cube.

Materials for the construction of a wooden house

As practice has shown, to buy timber today will not be any special work. On the market for the sale of building materials, there are plenty of offers, excellent in price and quality. But, as mentioned earlier, before buying you should calculate the required amount of building materials.

Modern sawmills can produce lumber of any shape and any size - with regard to the length of the timber, it mainly produces three standard cuts: 4 m, 4.5 m and 6 m long, respectively.

Even if you decided to build your house from sandwich panels, you just can't do without wood - the foundation of the roof of the house is built from it, and this material is used as a framework for building the roof itself.

Remember! The frame of the roof is made not only from timber, but also from boards, which must be purchased simultaneously with timber. In order to calculate the required amount of material, there is a special table of cubic capacity of the beam, which will help you quickly and easily determine the necessary figures.

Recommendations of specialists

So, as has already become clear, timber in construction plays an important role. Before buying it, it is necessary to carefully examine the products offered by the seller for the presence of cracks and other various defects.

In case you need to purchase a bar of a strictly defined size, first you need to consult with the seller - he will tell you whether such products are available or have to be made to order.

When ordering building materials be prepared for the fact that you have to wait some time.

After purchasing the board and timber, attention should be paid to such an issue as the delivery of materials directly to the object. If the seller has his own transport, he will be able to transport it himself at a reasonable price. In the event that the seller of transport is not - you have to independently look for a transport office.

After you managed to buy a timber and bring it to the object, you should take care of its storage. Under packages with building materials, you should put a small lining in the form of transversely abandoned bars or planks, and cover the wood with a tarpaulin or polyethylene on top.

When taking the necessary measures, the material will not deteriorate and rot. Proper storage will increase the service life of the material several times.

Conclusion

Well, that's basically all you need to know about the purchase, calculation and storage of the beam. Now you, as a "savvy" specialist - you can safely proceed to construction. On some construction sites there is a calculator for the cubic capacity of the beam to the house, with which it is quite easy to work online. We hope that this manual will help you in your work. Successes!
