Abstract

Today, the issue of the development of joints of wooden elements, in particular the joints of CLT and wooden beams, is topical. The aim of the work is to develop a nodal connection of wooden beams and CLT, which has increased reliability and has no drawbacks compared to the existing options for such connections in the world. The article presents the main existing ways of connecting wooden beams and CLT, their features, advantages and disadvantages are considered. Based on the world experience in joining wooden beams and CLT, it can be concluded that in most cases, for such purposes, factory-made metal supports of open or closed beams of various designs and shapes are used. The main disadvantage of such methods of connecting the considered wooden elements is the impossibility of making the connection hidden. This leads to a complete lack of fire protection of the connecting elements. It also requires additional finishing measures for supporting structures for an aesthetic purpose, which in turn increases the cost of construction. As a result, a constructive solution for the joints of wooden beams and CLT was developed, which has increased reliability compared to the studied joints and is devoid of their shortcomings.
