INTER-FRAME LINK OF MOUNTAIN TIMBERING MADE OF SPECIAL PROFILE

摘要

Inter-frame link of mountain timbering made of special profile has tie arranged as a metal rod with straight middle part and with yokes placed in mirror positions in one plane at its ends to surround special profiles of the neighboring fixation frames with tail elements at the ends, and stopping elements for formation of wedge joints with ties of neighboring inter-frame links. To increase reliability and technological properties of the inter-frame link the tie is arranged as a hollow rod with yokes in same shape, and the tail elements are placed in cross positions with respect to the straight middle part. At that the yokes and the sections of the straight middle part connected to those are arranged flattened in the plane placed normally to the plane where the yokes are placed, and the tail elements are arranged flattened in plane placed in the plane where the yokes are placed. In the flattened sections of the hollow rod long cuts are arranged for the tail elements of the ties of the neighboring inter-frame link, and in the flattened tail elements shaped long slots are provided to install there stopper elements arranged as shaped wedges and formation of wedge joints with cross-fixation with the ties of the neighboring inter-frame links.
