In many cases, lumber is used in the construction and repair of buildings. They are suitable for various types of work. No exception is the decoration of the premises and the building as a whole. However, first of all, it is necessary to calculate the cubic capacity of lumber.
Calculation process
As an example, take a room with an area of one wall of 18 m², where the width of the wall is 6 m and its height is 3 m. The total area will be this: 18 m²x4 = 72 m². In this case, 4 is the number of walls. We proceed to the calculation.
- The calculation of the cubic volume of lumber for the walls is determined by multiplying the area of the wall by the thickness of the board. In our example, this will be 72 m²x0.03 m = 2.16 m³, where 0.03 m is the thickness of the board.
- Similarly, we calculate the amount of interior decoration at home.
- We calculate the cubic capacity of lumber for the floor, ceiling and roof in the same way as for the walls.
- The volume of timber for the frame of the house will be obtained by multiplying the cross-sectional area of the timber (racks) by the length and the number of racks provided for by the house design.
The specific difficulty of selling and buying lumber is the correct calculation of cubic capacity. Even the regulatory authorities are not always able to verify whether the calculation is carried out correctly. Lumber from the manufacturer is delivered in its original packaging. It accurately indicates the volume and cost of production. If this is not the case, the buyer has to doubt whether the calculation of the cubic capacity of lumber and its value has been carried out correctly. The quality parameters of the boards are regulated by GOSTs, technical requirements, as well as various regulatory documents. It all depends on what kind of wood they are made of, what they will be used for. To determine the cubic capacity of round lumber, the corresponding GOST is also used.
Additional calculation parameters
In the woodworking industry, the concepts of a dense and folding cubic meter are used. To convert one quantity to another, a conversion factor is used. For example, the edged board in the price lists is indicated for calculating volumes in a dense mass. This calculation is not complicated. For this, the indicators of folding cubic meters are converted into dense masses using a special coefficient.
Measurement and calculation rules
For example, the croaker is sorted first in length by 2 types - up to 2 meters or more. Then it is stacked. In this case, thin and thick ends alternate. The stack is stacked as tightly as possible. In this case, the height and length should be the same. It is also necessary to withstand right angles in the stack. Multiplying the length, width and height of the package, we obtain a folding cubature.
Tip
It will also be useful to know that the rules for measuring each type of lumber are regulated by the relevant GOST. It has tables for calculating the volume of production. When selling a building bar or board, each unit of lumber is measured, according to the tables in GOST, the volume of edged lumber is calculated . You should also know that to determine the number of boards in 1 cubic meter, you need to calculate the volume of one board. This calculation is easy. Then we divide the unit into the volume of one board and get the desired number of products.
