MULTI-STOREY BUILDING OF COMBINED STRUCTURAL SYSTEM

The invention relates to construction, in particular, to the design of residential and public buildings for mass use with enhanced consumer qualities. A multi-storey building of combined structural system includes a load-bearing structure formed by cross load-bearing walls 1 and floor slab disks 2 containing cast-in-situ reinforced concrete beams 3 and prefabricated multi-hollow slabs 4. The slabs 4 are supported on concrete keys of the beams 3 and are interconnected by inter-slab seams 6. The building contains enclosing structures, including exterior walls supported on floor slabs or curtain walls and floor-supported partitions, according to layout solutions. Whereas, all cast-in-situ reinforced concrete beams located both in the planes of walls 1 and on the edges of the floor slabs are rigidly interconnected into closed frame cells. The slabs 4 are placed in cells in tight groups, at the ends they are embedded in the load-bearing walls 1 for the thickness of their protective concrete layer, and within these limits are additionally supported on these walls 1 by the lower shelf. Inter-slab concreted joints 6 in the middle of the cells of the floor slabs are fitted with a through reinforcing bar, anchored with its ends at the ends of adjacent slabs 4. At the intersections 12 of the load-bearing walls 1, one wall is made as a through wall 16, and the other is adjoining normally to it on one or both sides by means of a vertical contact seam 15. In the cast-in-situ reinforced concrete beam 3 of the floor slabs, additional reinforcing short bars are set crosswise to the through wall. The load-bearing walls 1 can be made of cast-in-situ reinforced concrete and fitted with vertical reinforcement continuous throughout the height of building. The load-bearing walls 1 can be made of precast and cast-in-situ reinforced concrete and include prefabricated flat panels on each storey and cast-in-situ vertical strip inserts between them, continuous throughout the height of building and fitted with vertical through reinforcement. The invention solves the problem of improving the consumer qualities of a building and reducing the prime cost of its construction.
