The invention relates to construction

Structures can be used to reinforce precast concrete structures.

i The purpose of the invention is to simplify manufacturing, reduce labor costs and save metal.

I Fig. 1 schematically shows one- 1 loop-loopbacks; in fig. 2 - two - 1 loop hinge frames; in fig. 3 - Q. Qas-loop of both types with an element for (distribution of pressure in the concrete of the slab in the loop; Fig. 4 - element for pressure distribution in the concrete of the slab in the zone of the mesh, top view; 5 - element, type; side.

Two-looped frameworks-loops {FIG. 2) are formed of a supporting rod, made with the bend of both ends in the form of mounting loops and are intended for plates with

welded to the metal plate 6 (Fig. 4 and 5). In the plate 6, one-sided inclined slots are provided, which allows the lining of this element to the frame-loop. This simplifies the production of plate reinforcement and reduces labor costs.

For plates in which the stress concentration in the slab concrete in the hinge zone is unacceptable takes place only during the removal of slabs from metal molds, it is possible to use a pressure distribution element on one side of the slab only (Fig. 3). loops from the side of these devices.

A loop frame with a pressure distribution element in a plate in the loop zone interacts with the latter, transferring a part of the load during the mounting operations on metal double sided loops. Single-loop cartographic plate, and through it - on the fastenings-loops 1 (Fig. 1) are formed from a supporting rod, made with the bend of one end in the form of a mounting loop, and can be used in plates with both double-sided and one-sided placement loops. In the frameworks-loops, 25 transverse rods are arranged 3.

The reinforcement of the plates in the transverse direction is performed by two two-looped frames-loops 2 (Fig. 2) or by four single-looped frames-loops 1 (Fig. 1), and when unilaterally placing the loops by two loops-1 frames and flat frames 4, what provides more uniform arrangement of fittings in longitudinal section of a plate.
