Such building material as wood has several serious disadvantages:
the appearance of cracks;
warping boards;
Frequent formation of greens.
These disadvantages affect the operational characteristics of the tree. However, whatever one may say, without this building material, not a single construction of a low -rise building is complete. In this regard, the market is replenished with all new types of wooden materials, among which glued beam is considered the most popular and in demand.
Such a beam is made in the factory. To create it, it is necessary to glue the boards with special equipment, which are pre -dried. The material is quite durable and has a very long service life. In addition, it is worth noting that glued beams are clean in terms of ecology. When using such building materials in the construction of the house, you are guaranteed to get excellent ventilation in the premises, that is, after a long absence in the house, the air will not stand in it, and will always be clean and fresh.
Glued beams were created in order to get rid of various disadvantages of an ordinary beam, which are natural. After his creation, three problems were solved at once – shrinkage after construction, the formation of cracks in the process of short operation and, of course, warning of the boards (change in their geometry). Due to this, in our time the house from such a beam is being built several times faster, the modern technology of building a house from this material also contributed to this.
Production of glued timber
For the manufacture of a beam, wood such as spruce, Canadian cedar, larch, and, of course, pine, are often used. Specialized equipment is used to glue the beam. A fully made glued beam has low humidity (from 8% to 10%), which gives a huge advantage to this material, since it has excellent resistance to rotting, deformation, and has high strength indicators. As for the shrinkage, this indicator does not exceed a mark of one percent. The technological process of creating glued timber consists of several stages.
At the very beginning of the logs, they are sawn into boards with certain dimensions, thus, they can be dried without cracks. Then they undergo several stages of treatment with various antiseptics and anti -piren. This is done so that they become more resistant to decay and fire. After that, an operation follows, during which the boards are compressed among themselves.
