Wood from ancient times is the most popular building material. The “living” tree is always in demand due to its natural properties. Not so long ago they began to use glued beams, but in their short time in construction, gained greater popularity. This material has a lot of advantages over other similar materials. Glued beam is quite technological, but not cheap material.
For the production of timber, coniferous woods are used, mainly spruce and pine. Glued structures are collected from boards, which are pre -dried in special chambers until certain humidity. The resulting raw materials are sorted, all defects are removed and strict from all four sides to give a geometric shape. The boards are necessarily treated with antiseptic solutions, to protect against insects and putrefactive bacteria. Then the boards glue and pressed under the hydraulic press. Assembly technology takes into account the direction of wood fibers. It must be opposite in each layer of timber. Such a beam is strong, practically not subject to shrinkage and deformations, has good sound insulation. For wall structures, gluing five lamellas – boards, to obtain a thickness of at least 20 cm, which increases its strength. In addition, the walls of the house collected from such glued beams have high thermal insulation qualities, correlated with the brick wall of the meter thickness. For the construction of suburban houses or cottages, glued beams are cut into parts of the desired size, and then holes for the bastards are drilled on special machines.
One of the important advantages of glued beams is its moisture resistance. This property is due to the design features. There are crests and grooves along the entire length of the beam, due to which this design becomes a monolithic. Lack of voids and cracks, processing of a beam with antiseptics and anti -Opens, increase its fire resistance 5 times compared to metal structures. In conditions of high fire hazard, the beam is able to maintain its operational qualities.
The maximum length of glued lamellas is 30 meters, and thickness up to 50 cm. This makes it possible to turn into life the most daring projects of architects. Glued beams are used in the construction of a variety of designation of structures. Houses or walls of glued beams do not change their shape, and the construction time is significantly reduced compared to the structure of ordinary wood. In addition, the design of glued beams is highly seismic resistance, therefore, are ideal for the manufacture of supporting elements up to 50 meters long.
