FIELD: building.
SUBSTANCE: bolted junction of thin-walled elements includes the upper and lower joining elements. The elements are overlapped on a gusset plate and tied between each other by means of a driftpin supplied with screws and plane washers. The screw is installed in coaxial apertures. Between jointed elements, rings with one-sided cone external surface are placed. Cone external surface is oriented toward thin-walled elements. The aperture in the gusset plate has a double-side reamer. The rings are disposed between the upper and lower elements and plain washers.
EFFECT: improved bearing ability of bolted junction.
