Calculation of the bar per house is necessary to determine the required amount of timber forthe construction of the roofing system, the implementation of formwork and the overlapping of the floors of the construction site. Its correct calculation is especially important in the construction of cottages from glued or sawn timber.

How to calculate the number of timber per house?

To properly orient in the needs of the lumber, it is necessary to make a design of the structure with an indication of the exact dimensions on which the length of the beam depends. Concerning its thickness, it is important to consider the following factors:

  • for a private house or baths fit a beam with a section of 200x200 mm;
  • for seasonal construction, it is possible to use wood with parameters 100x100 mm or 150x150 mm.

Based on the fact that the cost of wood building material is indicated in cubic meters, to calculate the exact number of pieces of logs in 1 cubic meter, it is necessary to make a simple calculation:

1m3 /Z/W/ L, where

  • Z is the width of the board;
  • W - thickness of the board;
  • L is the length of the board.

The design of the house includes the product of the calculation of the required volume of ceiling and floor beams overlap, the definition of sawn timber for the rafter system, external walls, pediments, internal partitions.

Often in the construction of ceiling and floor beams cross section of 100h150 mm using a step from 0.7 to 1 meter. In order to determine their number, you need to use the formula:

Ld / Ls-1, where

  • Ld - length of the house;
  • Ls - the length of the applied step.

Taking into account the fact that sawn timber is sold by the supplier in cubic meters, the calculation of the cubic capacity of the beam assumes the multiplication of its cross-sectional area and running length.

Calculation of the beam for external walls and load-bearing partitions involves determining the area and thickness of the walls. The multiplication of these parameters will give the total volume of the bar necessary for the construction of these structural elements.

For the exact calculation of the cubing of sawn timber on the rafter system, special arithmetic algorithms will be required. Calculator calculation of the beam will greatly simplify the task. The correct definition of the required building material guarantees the reliability of the construction of the structure and the saving of financial costs.

The program will allow you to calculate the bar online, by entering the original data. Changing the parameters you can compare several projects and choose the most profitable from a financial point of view. By processing individual parameters of the house design, the calculator will make the most accurate calculation, eliminating the risk of overpaying for excess material. It is important to consider the possible percentage of the marriage, which is about 5% of the total timber.
