Abstract

Use: construction of buildings and structures. SUMMARY OF THE INVENTION: a wall is made of rectangular blocks stacked in rows consisting of outer, inner and middle longitudinal plates interconnected by transverse partitions and forming cavities with the latter. The cavities on the side of the inner slab are filled with concrete, and on the side of the outer - heater. In the upper part of the block, fixing protrusions are made with bevels at their lateral ends, and in the lower part there are recesses corresponding to them. The protrusions and recesses are formed by the beveled ends of the outer and middle plates and the horizontal ends of the partitions located between these plates. The ends of the inner plates and adjacent partitions are located in the same horizontal plane. At the ends of the partitions adjacent to the inner plates, grooves may be made for mounting the fittings. 1 s P. f-ly, 5 ill.

Description

The invention relates to the construction of buildings and structures and can be used in the construction of external walls of a prefabricated monolithic structure.

A prefabricated monolithic wall is known, including rectangular building blocks stacked in rows, made with cavities, some of which are filled with insulation, and others are filled with concrete.

A disadvantage of the known construction is the absence of any structural elements for fixing adjacent blocks relative to each other.

Known precast-monolithic wall, which includes rectangular building blocks stacked in series from the outer, inner and middle longitudinal plates, interconnected by transverse partitions and forming cavities with the latter, which are filled with concrete from the side of the inner plate and insulation from the side of the fusible, fixing protrusions with bevels on their lateral ends in the upper part of the block and the corresponding, recesses in the lower-.

This technical solution is closest to the invention.

Its disadvantage is that the formation of the base units of the floor slabs requires the use of special types of building blocks, which makes the construction technology more expensive and complicated.

The purpose of the invention is to improve performance.

This is achieved by the fact that in a prefabricated monolithic wall, comprising rectangular building blocks stacked in series from the outer, inner and middle longitudinal slabs interconnected by transverse partitions and forming cavities with the latter, which are filled with concrete from the side of the inner slab and insulation

gating - on the outer side, the locking protrusions with bevels on their lateral ends in the upper part of the block and the corresponding recesses in the bottom, the locking protrusions and recesses are formed by the beveled ends of the outer and middle plates and the horizontal ends of the partitions located between these plates, and the ends of the inner plates and adjacent partitions are located in one horizontal plane.

At the ends of the partitions adjacent to the inner plates, grooves are made for installing reinforcement.

In FIG. 1 shows a prefabricated monolithic wall, view in plan; in FIG. 2 is a section AA in FIG. 1; in FIG. 3 - building block; in FIG. 4 - section BB on Fig. 3; in FIG. 5 - corner block.

The wall 1 is made of building blocks 2 laid in rows. Each block 2 consists of an inner 3, an average 4 and an outer 5 longitudinal slabs interconnected in the middle by transverse partitions 6 and 7. The cavities between the inner 3 and the middle slabs are filled with fill insulation 9 In the upper part, the blocks are made with locking protrusions 10, and on the side of the lower ends with mating depressions 11 to increase the accuracy of fixing blocks of adjacent rows relative to each other. The protrusions 10 are formed by side bevels 12 on the middle plate and 13 on the outer plate and a horizontal plane 14 on the partitions 7. The upper ends of the inner plate 3 and the adjacent partitions 6 are formed by one horizontal plane 15. Grooves 16 can be made in the partitions 6 for

Half blocks 17 can be formed by removing the inner wall of the plate 3 and partitions 6. The corners and openings of the structure can be formed from angular

blocks 18. This embodiment allows the formation of a monolithic support for floor slabs 19, which will increase the reliability of the structure in conditions of increased seismicity.

0 The placement of transverse partitions 6 and 7 in the middle of plates 3, 4 and 5 and filling the cavities with insulation made it possible to prevent the formation of through bridges of cold.
