YIELDING CONNECTION LOCK OF METAL FRAME YIELDING SUPPORT MADE OF MINING SPECIAL PROFILES

摘要

Yielding connection lock of metal frame yielding support made of mining special profiles includes slat with openings and fixation cramp of-like shape with threaded ends that go through openings of the slat, placed between those with lap the inner and the outer special profiles, nuts, and reinforcing-stabilizing elements installed between the slat and the flanges of the inner special profile that include inner side walls that are in contact with the side walls of the inner special profile, outer side walls and parallel shelves with openings through which threaded ends of fixation cramp go. Reinforcing-stabilizing elements are arranged as continuous and each of side walls of those has shape of cylindrical panel curvature of which is directed to the side of placement of special profiles. The outer side walls are in contact with fixation cramp and have same radii of curvature of surfaces with inner side walls.
