Research of strength of gluing of wood

Wood is widely used in industrial and civil engineering. It has many valuable physical, mechanical and other operational properties that make it widely possible to use it not only in construction, but also in other sectors of the economy. Many scientists studied the problems of studying the processes of mechanical processing of wood and the development of rational technological conditions and modes of gluing wood, allowing to obtain products with the required physical and mechanical properties. One of the ways to increase the efficiency of production of glued building materials from wood is gluing lumber along the length of the toothed spike. The strength of glued beams during operation depends on many factors, including the quality of the formation of adhesive joints. The main ones are the properties of wood, mainly density and humidity, and the type of glue. The surface relief, the type of surfaces to be glued, the dimensions and the shape of the ten on also have an effect. The results of a study of the bonding strength of wood in glued beams and the strength of finger jointing are presented in this article.
