The invention relates to construction and can be used in the construction of large-panel buildings in seismic areas.

The purpose of the invention is to increase the seismic resistance of the joint.

FIG. 1 shows a butt joint, a section; in fig. 2 — joint key, general view; in fig. 3 shows section A-A in FIG. one; in fig. 4, 5, and 6 are embodiments of the keys for the corner mates of the abutting elements, in perspective view; in fig. 7 is a butt joint with the key shown in FIG. 4, the cut; in fig. 8-11 are the butt joints of the building elements with the keys shown in FIG. 1-6, respectively, top view; in fig. 12 is a section BB in FIG. 9; in fig. 13 is a section B-B in FIG. eleven.

The butt joint of building elements 1, predominantly wall panels, includes sockets 2 formed on joined edges and located opposite each other, and a concrete key 3 in the form of a truncated sphere placed in them, enclosed in a shell 4 of elastic material, equipped with paired elastic half rolls 5, which are located along the truncated ends of the key 3 on the outer surface of the shell 4. Reinforced rubber can be used as an elastic material in the manufacture of the key shell 3.

The key 3 is provided with anchor lugs, which are folded upward on the assembly.

When connecting the building elements 1 (wall panels) with the floor slabs 7, the latter are made with bevelled corners, where the mounting loops 8 are installed, in the space formed by the Bevels of the floor slabs 7, communications 9 can be missed.

When mounted in loops 8 of the plant and anchor outlets 6 and tighten them. The overlap plates 7 are additionally connected to

wall panels 1 elastic-elastic connections 10.

Under the conditions of seismic effects, as well as the effects of mine workings, the relative displacement of the wall panels 1 occurs from the transfer of shear forces through the system of half-shafts 5 of the 4-key shell 3. The return of the displaced wall panels to their original position is ensured rolling functions, since with an increase in the angle of inclination of the lower part of the wall panels, horizontal joints between the upper and lower wall panels with a rise in the center of gravity of the superior panels and floors, as a result of which a horizontal force arises opposite to the seismic effect, i.e., the magnitude of the horizontal load decreases.

The application of the invention will allow to reduce capital investments in the construction of high-rise buildings in seismic areas due to the refusal to carry out protective reinforced concrete.

Claims (2)

1. A joint connection of building elements, including sockets formed on joined edges and located opposite each other, and a concrete key placed in them and encased in a shell, characterized in that, in order to increase the seismic resistance of the joint, the shell is provided with paired elastic half-rolls and made of an elastic material, and the key has the shape of a truncated spheroid, while the paired half rolls are located along the truncated ends of the key on the outer surface of the shell. 2. Compound according to claim 1, of which it is so that reinforced rubber is used as the elastic material. FIG. 2 -A, - Fig. 3 FIG. one 5  Wx lHH 1xxxYA c ± 2 vvvy LXAH fc QO CO i
