FIELD: construction industry. ^ SUBSTANCE: invention refers to construction industry, and namely to bar construction joint. Construction joint consists of bearing bar, whereon crossbars and connecting plates are rested. Crossbars are attached to each other angle-wise. Bars section is made in the form of I-beam profile. I-beam web is made from veneer sheets. Flanges are made in the form of blocks fixed along longitudinal plate edges. Bearing bar section comprises the number of veneer sheets equal to the number of veneer sheets used in crossbar construction, but plus one more sheet. Bearing bar sheets are located with a gap equal to thickness of crossbar sheets. If bar construction consists of at least two veneer sheets, they are attached to each other with transverse stiffeners located in gaps. Joint of crossbar veneer sheets passes through gap between the bearing bar veneer sheets and has no appropriate flange sections. Edges of the rest crossbar flange sections contact bearing bar flange surface facing them. Joint section along the surface of bars joint passing through a gap between bearings bar veneer sheets and throughout the thickness of this section is provided with tightening elements e.g. bolt screws. ^ EFFECT: improving bearing capacity, and reducing consumption of joint materials. ^ 8 cl, 3 dwg |
