Description

The invention relates to construction and can be used in the construction of low-rise buildings in seismic regions.

A known analogue of the method of laying tiles in the application for invention No. 2014152378, IPC E04F 21/00 from 23.12.2014, publ. 07/20/2016, which consists in the fact that when laying tiles, the adhesive under pressure fills the space between the tiles and the supporting surface by means of manual or mechanized supply of the adhesive through at least one tube of a suitable section, as a result of the pressure generated, the tile rises relative to the supporting surface and rests against the outer side in beacons installed above the surface to be clad.

Disadvantages: insufficiently strong structure, increased consumption of building materials.

Known is the closest analogue of a method for erecting a layered monolithic wall and a hollow ceramic stone for erecting a monolithic layered wall in the description of the invention to patent No. 2148130, IPC E04B 2/28, from 03.08.1999, publ. 04/27/2000, including the creation of internal and external surfaces from formwork elements and pouring a concrete mixture, characterized in that hollow ceramic stones with grooves on the side faces are used as formwork elements, while the grooves on one side face along the stone are made in the form of a dovetail tail, and on the parallel face the grooves are made with a depth of 1/20 - 1/30 of the thickness of the ceramic stone, and imitate brickwork, and a mixture containing wt. %:

Ash from the incineration of industrial and domestic wastewater from municipal utilities - 25-40

Portland cement - 40-25

Aluminum powder - 0.1-0.15

Water - Rest

at the same time, before pouring, the inner and outer surfaces of the wall are additionally connected by elements with ends made in the form of a dovetail and interacting with the grooves of ceramic stones, and pouring is carried out repeatedly in equal doses and the dose of each pour is determined by the formula (V / F) ≤ 0.2- 0.4, where V is the volume of the potting mixture, m3; F is the area of the filling space, m2.

Disadvantages: not strong enough.

EFFECT: increased structural strength with reduced consumption of building materials.

The technical result in the method of erecting a monolithic wall, including the creation of internal and external surfaces from the formwork elements, the laying of the precast coating slabs and the pouring of the concrete mixture between the formwork, is achieved due to the fact that the prefabricated coating slabs are installed in several rows to the inner side of the formwork, consisting of the upper side, two side walls, with a through open groove in the T-shaped section, made on the lower side of the slab, then one outer row of reinforcement is sequentially installed with a distance of 10-100 cm between the reinforcement in one row, and all the reinforcement is tied together with wire in the reinforcing structure, install a heater, install a second row of reinforcement with a distance of 10-100 cm between the reinforcement in one row, and all the reinforcement is tied together with a wire in the reinforcement structure, then two rows of reinforcement are tied together, the internal formwork is installed at a distance of x = 4z / 3, where z is the distance from the outer row and reinforcement to slabs, x is the distance from the inner row of reinforcement to the inner formwork.

The essence of the invention is illustrated by drawings, where FIG. 1 shows a method of erecting a monolithic wall using precast slabs;

in fig. 2 shows a method of repairing facade walls using precast slabs.

The proposed method for the construction of a monolithic wall is as follows. An external formwork is installed, to the inner side of which prefabricated slabs are installed in several rows, consisting of the upper side, two side walls, with a through open groove in the T-shaped section, made on the lower side of the slab, side walls on top of each other. Plates are installed with an open groove inside. The top side of the slab can be multi-colored, which makes it possible to build a wall with various patterns. One outer row of reinforcement is installed with a distance of 30-50 cm between the reinforcement in one row, and all the reinforcement is tied together with a wire into the reinforcement structure. After the outer row of fittings, a heater is installed. Then a second row of reinforcement is installed with a distance of 10-100 cm between the reinforcement in one row, and all the reinforcement is tied together with a wire into the reinforcement structure. Then two rows of reinforcement are tied. The inner formwork is installed at a distance x = 4z / 3 (4: 3), where z is the distance from the outer row of reinforcement to the slabs, x is the distance from the inner row of reinforcement to the inner formwork. Concrete is poured between the formwork and the reinforcement structure. The concrete solution enters the grooves of the precast coating slabs, which have many points of adhesion to the concrete mortar; when the mortar dries, a concrete plug is formed in the grooves of the slabs, ensuring solidity.

To repair the front walls, install a heater if necessary, then reinforcement, tie and attach it to the wall, then put several rows of prefabricated coating slabs, consisting of the upper side, two side walls, with a through open groove in the T-shaped section, made on the underside of the slab, side walls on top of each other, with an open groove inward. On the upper side of the slab, a colored coating can be made, which makes it possible to build a wall with different patterns. The formwork is installed, the slabs are aligned with the formwork and poured with concrete.

An external formwork is installed, to the inner side of which precast slabs are installed, consisting of the upper side, two side walls with a through open groove in the T-shaped section made on the lower side of the slab, side walls on top of each other.

One outer row of reinforcement is installed at a distance of 6 cm from the slabs, with a distance of 30 cm between each other, and all the reinforcement is tied together with a wire into the reinforcement structure. After the outer row of fittings, a heater is installed.
