Use of glue-laminated wood in industry

Abstract

Wood is popular with developers, it is chosen for the construction of load-bearing structures, decoration, and creation of various interior items, small architectural forms. Natural material is undoubtedly good and environmentally friendly, but ordinary timber and boards have significant disadvantages: a tendency to change volume when humidity changes, drying out, deformation, and knots. These unpleasant consequences are practically excluded when using glued timber as a structural material and are used in various sectors of the world economy.

Glued timber is a material made by gluing layers of processed wood, where each layer is located perpendicular to the direction of the fibers. For production, mainly pine and spruce trunks are used.

The purpose of this article is to establish the scope of the application of glued timber and list its advantages compared to other traditional materials.

A detailed analysis of literary sources on the features of the use of glued timber has been carried out. The main physical and mechanical properties of glued laminated timber are characterized and analyzed in detail, and its structural schemes are given.

Wood, like other materials (metal, concrete, reinforced concrete, polymers), is exposed to various active aggressive environments. The scope of application of elements and materials based on glued laminated timber in various sectors of the economy is given, in particular, construction, woodworking, furniture, mining and quarrying, mechanical engineering, and others.

It has been established that one of the main advantages of glued laminated timber is its high mechanical strength and stability. Unlike solid wood, glued laminated timber is less prone to warping, cracking, or changing shape under the influence of temperature and humidity changes. This is achieved due to the fact that wooden lamellas are carefully processed and arranged so that the wood fibers alternate before gluing, which allows reducing internal stresses.
