Abstract

The invention relates to multi-storey buildings of bulk blocks. The aim of the invention is to reduce the labor intensity of installation. The inclined faces of the protrusions located at the corners of the slab of the floor of the bulk blocks interact with the inclined edges of the rib located along the contour of the floor slab of the overlying bulk block. Volumetric blocks adjacent in plan are interconnected by threaded elements that are passed through the holes in the brackets installed on the floor slab and inserted into the cutouts of the floor plate edge. In the vertical and horizontal joints between the blocks are placed elastic pads. Disc springs can be mounted on the threaded elements. 1 hp f-ly, 4 ill.

Description

The invention relates to the field of construction and can be used in the construction of multi-storey buildings from bulk blocks.

The purpose of the invention is to reduce the labor intensity of installation.

FIG. 1 shows a fragment of the building in plan; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 - the same, version with cup springs.

The multi-storey building contains volumetric blocks 1 and panels of 2 external walls.

The slab of floor 3 of each block 1 has along the contour a rib 4 with an inner inclined face 5 and notches 6. The latter are made only in the edges 4 of block 1 located inside the building. The cover plate 7 of the blocks 1 has in the corners of its outer surface protrusions 8 with external inclined edges 9 interacting with the inclined face 5 of the edge 4 of the floor plate 3 of the overlying block 1.

Each unit 1 is provided with brackets 10 in the form of corners with a hole 11 in one wall 12. The other wall 13 bracket 10 is rigidly attached to the fixing part 14 in the cover plate 7. The brackets 10 are mounted along the contour of the last in the cut-outs 6 of the rib 4 of the plate 3 of the upper block 1.

In the horizontal joints between the blocks 1 and the outer wall panels 2, elastic gaskets 15 are placed, and in the vertical joints between the blocks 1, additional elastic gaskets 16 attached to the walls 17 of the blocks 1 are discretely opposite each other. Between the brackets 10, the floor slab 3 and the walls of the cut-outs 6, gaps 18, 19 are provided for ease of installation. The blocks 1 are interconnected by horizontal connections in the form of threaded elements 20, for example bolts, placed in the holes 11 of the brackets 10 and secured by nuts 21.

To increase the seismic resistance of the building, the cup springs 22 can be mounted on the core of each threaded element 20 and placed between the wall 12 of the bracket 10 and the nut 21 of the threaded element 20 on one side, as well as between the wall 12 of the bracket 10 and the head 23 of the threaded element 20 s the other side. Such an arrangement of horizontal communications allows the bulk units 1 to make elastic displacements relative to each other during seismic shocks.

The ribs 4 of the floor slab 3 and the protrusions 8 of the slab of the coating 7 are made at the factory when the elements of the bulk blocks 1 are manufactured and the brackets 10 and elastic gaskets 15, 16 are also attached to the blocks 1.

The building is erected in the following order: the foundations are installed, the lower row of blocks 1 is installed and interconnected by tensioning the threaded elements 20 until the nominal size of the seam between the blocks 1 is reached. Then the upper blocks 1 are installed on the lower blocks 1 when the interaction of the inclined faces 5 of the ribs 4 of the floor slab 3 of the upstream blocks 1 and the protrusions 8 of the slab of the floor 7 of the downstream blocks 1. The upstream blocks 1 are also interconnected by means of threaded elements 20.

The invention makes it possible to reduce the labor intensity of installation of a multi-storey building, as well as to increase its seismic resistance,
