The amount of timber in a cube, why you need to know it and

Manufacturing companies and sellers in the construction markets sold timber measured in cubic meters. For ignorant people, counting the right material often causes certain problems than sellers use.

However, it is not at all difficult to convert timber from cubic meters into pieces and vice versa. To this end, you need to find out the volume of one beam, multiplying its thickness, width and length.

Some subtleties you need to know

1. It should be noted that the number of bars in one cube never amounts to a round figure. For example, a material with a cross section of 100? 150 mm in a given volume of 11.11 pieces. The dishonest sellers round this value down. As a result, acquiring several cubic meters of timber you will not be able to count several bars.

Note! Based on this circumstance, the optimal solution is to calculate in advance not the number of cubic meters of timber you need, but the number of its units. You should know that the volume of the purchased timber in cubes and its number in pieces should be indicated by the sellers in the invoice issued to you.

1. Specialists use the concept of “calibrated” and “uncalibrated” timber. They have different tolerances from the standard sizes, they are also different in price. When building a house need calibrated bars, because uncalibrated beams, as a rule, have smaller sizes.
2. Another point is related to the size of the material. As a rule, the average length of the boards is not 6, but 6.05 meters. This happens from the fact that their ends were not processed during the cut or go at different angles. Some sellers take this into account when selling material. However, this approach is cheating.

1. It is also necessary to warn that some manufacturers and traders of timber are deceiving their customers. Often there is a situation when the real section of the beam is less than the declared. So, a material with the specified dimensions of 150? 200 mm may actually have a cross section of 140? 190 mm or even less.

Note! On this basis, it is imperative that you verify these material parameters before purchasing it. So you will not save your nerves and money.

Calculation of the consumption of timber

All calculations are indicative only. The exact amount of building material required is determined on the basis of the project of a cobbled building.

Necessary calculations

On the walls of the bars the desired cubic capacity can be calculated in this way.

1. First, the perimeter of the building is measured.
2. Further, it is multiplied by the height of the walls of one floor.
3. The number found is multiplied by the thickness of the beam to be used.
4. The result is the number of cubic meters needed for the construction of the floor.

When, in addition to external walls, internal partitions are assembled from a timber, they should be taken into account. If necessary, you can calculate not only how much material is needed by volume, but also the number of pieces of timber in a cube. For this purpose, the total volume found is divided by the analogous parameter of one bar.

As an example, we present the calculations for a small house 5? 7 meters. It will have an attic, one inner wall and a pediment from a bar. The height of the floor will be 3 m. To work we take a bar, having dimensions of 150? 150.

Calculations look like this.

1. The perimeter of the building, along with the length of the partition: 5 + 5 + 5 + 7 + 7 = 33 meters.
2. The volume that the walls of the first floor have: 3 • 33 • 0.15 = 14.85 m ?.
3. The cubic capacity of the material for the gable is counted as half of the timber required for the construction of two walls, 3 m high and 5 meters long: 3 • 5 • 0.15 = 2.25 m?
4. So, will the walls need 17.25 m? bars We add 20% to the stock and get a figure of 20 m ?.

How many bars do you need for construction?

A simple calculation makes it possible not only to calculate the volume of timber, but also to find out the exact number of bars needed to construct a building. To do this, you need to know the total volume of the material and the volume of one piece. The first digit will need to be divided by the second.

Below is a table of the number of beams in the cube of the most demanded sections, as well as the volumes of individual beams. The length of the product is mainly 6 m. The beam of the last two sizes has a length of 7 m.

About the size of the material

The dimensions used when laying log timber, are of great importance. However, his choice should be approached on the basis of economic feasibility.

Mainly, here you need to take into account the thickness of the walls and the heat-conducting properties of the timber.

Note! The width of the bars is important only when you plan to live permanently in the house built from them. This parameter can be ignored, since wooden walls can be protected with a reliable heat-insulating material, thus avoiding heat losses.

1. If you are going to build a country house, a timber with a cross section of 100? 100 millimeters is suitable for it. It should be noted that if you decide to use cheap unplaned timber, you will have to take care of the decorative lining of the facade of the building, as well as interior decoration of its walls.
2. When building a building for permanent residence, it is best to purchase a profiled or glued laminated timber with a thickness of 15 cm. But even here the optimal solution is to insulate the walls from the timber.

In order for a house of lumber to be truly warm, according to SNiP, its walls must be of a thickness of 40 centimeters or more, based on the climate of the region. For example, in the Moscow region, this parameter is 50 centimeters. The same level of heat saving can be achieved by applying bars, a cross section of 150? 150 mm and a layer of insulating material with a thickness of 10/15 centimeters.

Construction estimate

Before you choose a construction company that will build your block house, analyze the proposals. To find the most economically feasible option, request a construction estimate for the project you have chosen.

In such a document should be spelled out all the financial costs associated with the construction of the building. They should include the cost of all construction and facing materials, as well as the cost of all types of work.

It should be noted that many companies provide estimates for the construction of free. As for the cost of building a house, it can differ very much in different companies, up to 100/200%.

It is recommended to have the most detailed list of materials and works necessary for the construction of the house according to the drawn up project. This way you will avoid unexpected costs that arise during the construction of the building.

In general, the estimate for the future home, you can make yourself. For this purpose, calculate the consumption of all building materials, then multiply the resulting quantity by average prices. Next, add to the resulting figure about 50/100% of the cost of materials. This will be the cost of the work.

The resulting calculation of the cost of the building will be only an approximation. However, they can be operated in analyzing the proposals of construction companies.

Conclusion

Calculate the number of required timber for the construction of a building from it is quite simple. Having completed the calculations, you will know not only the material consumption figure, but also the cost of its purchase. The video in this article is ready to answer the remaining questions, see!
