The invention relates to a bow as an additional device for the mine reinforcement of the corridors, which support the casing against the fall of the ceiling arc of the reinforcement when mechanically building the reinforcement and the casing feeder.

The prior art is characterized by the fact that the double-walled casing on the ceiling arches of the stiffener is tied with a drot and, moreover, the pistons are supported on them. The disadvantage of this condition is that the outer casing needs to be tied in a dramatic manner, which requires a lot of time because it is difficult to make the casing so that the casing does not fall and the workers are not injured. In addition, it is necessary to have a stock of pulp to bind the casings, and the skull is consumed by remaining on the stand after it has been installed in the mining passage.

The above-mentioned drawbacks are eliminated by the clause of the mine reinforcement according to the invention, characterized in that its resilient sleeve is provided with a catch, a latch and a support is inherent in its elasticity attached to the edges of the reinforcement and to its opposite part. The advantages of the mine reinforcement according to the invention are that the use of the mine reinforcement eliminates the need to tie the reinforcement with the reinforcement by the drill, the use of which is fast, or these are attached to the reinforcement by impact on the sleeve or the bumper and also repeatable because the bowls do not remain on the stiffener, but are made of it for the purpose of use. 2

1 shows a post-hunger in the direction of the letter P, according to FIG. 3, a ceiling arc of a stiffener with stanchions and hives; FIG. 2 is a view of the letter R of FIG. Fig. 3 is a perspective view of the letter S according to Fig. 1 on the stanchion with the casing.

The mine reinforcement column consists of a resilient sleeve 1, which is provided with a catch 2a latch 3 for securing the mantle 7, further from the support 4 for supporting the mantles 12 on the reinforcement 7 and from the handle 5 intermittently scanning the mantles from the reinforcement 7. Handle 3 can be replacing the bumper 6 with rebounding from the reinforcement 7 by means of a bar, if they are bowing high and out of the reach of workers. The attachment of the bow 7 is made so that the catch 2 engages the edge 8 of the reinforcement 7, the catch 3 is attached to the opposite portion 9 of the reinforcement 7 and then the elastic sleeve 1 is punched in the direction of the arrow 10 on the handle 5 or the bumper 6 is fixed by a latch. 3 on the opposite part 9 of the reinforcement 7. When the reinforcement 7 is provided with stanchions, it is possible to store the casing 11 and transport it with the reinforcement 7 to the building of the mining passage. After the reinforcement 7 and the casings 11 have been incorporated in the tunnel, the bows are removed from the reinforcement 7 by punching in the direction 12 on the handle 3 or the bumper 6, while the casing 11 remains permanently pressed against the ceiling in the reinforcement 7. 216 838
