FIELD: construction. ^ SUBSTANCE: invention may be used in construction and machine building for fixation of thin-sheet material to bearing structure. Method for bolt connection of parts with different thickness from sheet structural material that operate for shift from loads effect includes installation of bolt in openings of joined parts and its connection with nut. Bolt is installed from the side of thick sheet, and nut is arranged with protrusions installed evenly on its support surface, and is installed as inverted with its surface to the side of thin sheet. When tightening bolt connection, nut is retained from rotation, and bolt is rotated. Surface of nut on the side of its support surface is arranged with protrusions in the form of crosses or cones or semi-spheres or inclusions from corundum crumb. ^ EFFECT: higher bearing capacity of joint is achieved. ^ 5 cl, 5 dwg |
