What kind of timber is on the floor

In the construction of low-rise wooden houses is irrational to mount the concrete slab. It is more logical to use wood, namely timber. How correct is the calculation of the cross section of beams and their number is directly dependent structural stability of the buildings and its durability. Note that the main weight falls on the connecting elements built – overlapping. Therefore, the choice of timber should be treated seriously.

How correct is the calculation of the cross section of beams and their number is directly dependent structural stability of the buildings and its durability. Note that the main weight falls on the connecting elements built – overlapping. Therefore, the choice of timber should be treated seriously.

Length of beams should be 50-60 cm more than the length of the shortest wall (in this case 3 meter). This requirement is due to the fact that in accordance with the norms of building of low houses timber floors must lean on the wall so that both its end was placed on them not less than 25 cm If the building is built of brick, timber brought in specially left for this purpose, the openings that form in masonry. The wooden walls of the holes are cut just. The beam is placed on the waterproofing material – the roofing material.

When choosing timber you should know that the best strength characteristics differ by 2-4 m of the workpiece. Optimally, if the thickness (height) is 1.4-1.5 times longer than wide. Builders to determine the most appropriate cross-section are tables that take into account the estimated weight and length of span. For core areas, the average unit load is 400 kg/m2.

For slabs it is recommended to choose a well-dried wood treated with antiseptic and flame retardants. The end surface of the need to independently process the bioprotective agent. You can buy lumber made of larch conifers.

It is recommended to examine wood for the presence of knots. The fewer, the better its quality. If the length of timber more than 4 meters, should make an extra supporting wall, or the ceiling will SAG. To give it greater strength and stiffness, timber tightening the metal studs so that the beams formed a single canvas.
