SU47959A1 - Elastic connection of separate parts of mine mechanical support without the use of auxiliary connecting parts - Google Patents

Description

-Patent No. 47958 describes the elastic connection of individual parts of mine metal lining without the use of auxiliary connecting parts, in which, when mine lining is made of I-beams, the wall of one of the beams at the junction is cut to a certain length, and both shelves move along the surface of the second fiber beams, moreover, in order to form a stop for a piece of wood inserted between beams, corners are attached to the walls of both beams on both sides.

The present invention is a further development of the described compound.

In the proposed modification of the elastic joint at the joint, plates are welded to the shelves of the corresponding beam and the other is loosely mounted on the shelves in order to form a stop for the piece of wood inserted between the beams.

()

the second beam, which shelves, provided with notches, are passed through the notches of the slab under the first oalka shelf.

With such a joint, the lateral displacement of the beams with respect to one another at the joints is eliminated, and when compression occurs, the joint becomes more dense and strong, as the parts entering each other more and more move inward.

In FIG. Figure 1 is a side view of the elastic joint of individual parts of mine metal support without the use of auxiliary parts; FIG. 2 - its top view; FIG. 3 is a side view of the compound in another form; FIG. 4 view it from above.

I-beams 1 are used to form supports. The wall of one beam at the junction is cut out, and on the residual ends of the shelves 4, appropriately cut plates 2 are put on, which are pushed all the way into the walls. While one plate is held together

by welding in several places 3 with shelves 4 beams, the second slab is put on the shelves only freely.

The free ends of the shelves 4 enclose a round piece of wood 5 placed between the beams and are provided along the edges with slots 6 of somewhat greater width than the wall thickness, so that these ends can pass through the slab 2 on both sides of the steak under the shelves of the second I-beam.

With the connections shown in FIG. 3 and 4, the assignment of the plates 2 is carried out directly by the hanging ends of the shelves themselves. Consequently, only one end of the shelf 4 of each I-beam 1 enters, blessed cut b, under the opposite shelf of the second beam, meanwhile

the other hanging end of the flange 7 is bent towards the cut wall and partially covers the compressible tree 5.

The subject matter of the invention.

Modifying the elastic connected parts of the mine metal support without using auxiliary connecting parts according to patent No. 47958, which is different in application, to form a stop for a piece of wood inserted between the beams, placed at the junction of two plates 2 and 2, one of which is welded to the shelves beams, and the second one is worn on the shelves of the second beam of shelf 4 that are missed under the shelves 4 freely.
