We want to dispel the myth that the tree as building and finishing the material cannot and will not shrink the structure constructed with its use, even having passed the drying procedure in the conditions of production before this.
The construction can shrink in three cases: – if the beam decreased, because excess humidity evaporated from it; -due to the severity of the structure itself, provided that the intervention spaces were reduced; -If the donkey is a soil due to pressure by the foundation.
Even if you carefully dry the wood, placing it in a special camera, you still cannot avoid the above processes. Adhere to special rules when erecting structures from wooden.
Due to the above properties of the tree, as the material of construction and decoration, when planning and erecting structures, specialists carefully calculate the percentage of possible shrinkage of the building.
Permissible limits – 5 %, if you use a beam with a natural moisture level. 1 % – if the beam is glued and profiled. More acceptable norms are a production marriage.
If the walls of the structure are collected poorly, then the wood can crack. So that the structure of the wood is not supplied to twisting, it is necessary to use the dug and spring blocks.
