FIELD: construction industry.

SUBSTANCE: invention refers to construction industry, and namely to joints of wooden bar constructions. Construction joint consists of wooden in cross section I-beam bars the ends of which are attached to each other angle-wise and are secured with connecting plates. Bar web is made from at least two veneer sheets arranged with a gap and attached to each other with transverse stiffeners, and their flanges are made in the form of blocks. Edges of flanges and webs of two bars contact each other and are attached to the third in cross section I-beam bar. Third bar web is made from veneer sheets, the number of which is the same as the number of veneer sheets used for construction of first bars minus one sheet. Veneer sheets of first bars are arranged with a gap equal to thickness of third bar sheets. End section of third bar which passes through the gap between veneer sheets of first bars has no appropriate flange sections. Ends of the rest sections of the third bar flanges contact the first bars flange surfaces facing them. Connecting plates made from veneer with thickness equal to that of webs are arranged in the gap between veneer sheets of first bars, in contact with longitudinal edges of third bar webs, and on outer planes of first bars.
