Description

one

The invention relates to the fastening of mine workings.

The known lattice of the cable consisting of longitudinal and transverse rods interconnected 1

Closest to the invention, the technical solution is to construct a fastener for frame supports of mine workings, consisting of transverse rods and LONG-TERM rods rigidly connected to them with end-loops and connecting elements 2.

The disadvantage of these constructions is that they do not fix the position of the arch (frame) when it is installed. To fix the positions of the arch, it is necessary to install an additional device, which increases the complexity of the work.

The purpose of the invention is to increase labor productivity when installing the fastener by fixing the position of the frame.

The goal is achieved by the fact that the longitudinal rods are provided with additional loops located from the end loops at a distance equal to the width of the support profile.

FIG. 1 depicts an offer-; in FIG. 2, the same plan view.

The grille consists of transverse rods 1, longitudinal shears 2 welded to them with loops 3 at the ends provided with additional loops 4 located from loops 3 at a distance equal to the width of the lining profile 5, and connecting elements b.

The fastening process with the proposed clamp is as follows.

five

For the installed support 5, the U-shaped curved longitudinal rods 2 are formed, which are connected by elements b. Console jutting loose ends are connected

0 in a similar way with the following sections Zat. Then in P-framed curved longitudinal rods the lining is put 5.
