Abstract

FIELD: building, particularly to erect load-bearing building walls.

SUBSTANCE: device comprises frame structure composed of frame members connected one to another by cross-pieces. The frame structure is mare as three-dimensional grid defining cells. Each cell is formed of two frames with holes located at frame corners and connected one to another by cross-pieces arranged in frame corners. The cross-pieces are provided with locks. Each lock is made as angle member and plate bent in two steps. The angle member and the plate are connected by rectangular plate.

Description

The invention relates to the field of construction, and in particular to methods and devices for the construction of buildings.

The prior art method of erecting walls of a building, including mounting frame-forming elements, installing them in the design position, formwork sheathing, filling with a hardening solution the space between the formwork and frame-forming elements (see patent FR 2406041 A1, 05/11/1979).

The disadvantage of this method is its rather complicated implementation and high material costs.

In addition, a prior art device is known for implementing a method of erecting load-bearing walls of a building, comprising a frame formed by plates connected by jumpers (see US Pat. No. 5,809,728 A, 09/22/1998).

The disadvantage of this method is the insufficiently high reliability of the frame during operation.

An object of the invention is to simplify the method of erecting load-bearing walls of buildings through the use of porous concrete and create a universal framework design, which allows for the erection of load-bearing walls with the required strength in building conditions while increasing its reliability and reducing material costs.

The problem is achieved due to the fact that in the method of erecting the load-bearing walls of the building, including mounting frame-forming elements, installing them in the design position, covering the frame with formwork, filling the space between the frame-forming elements and the formwork with a hardening solution, the frame is made in the form of a spatial lattice structure, and in as a hardening mortar, porous concrete having a density of 150 to 1200 kg / m ^{3 is used} .

The task is also achieved due to the fact that in the device for implementing the method of erecting the load-bearing walls of a building containing a frame of elements connected by jumpers, the frame is made in the form of a spatial lattice formed by frames connected by jumpers equipped with locks, each of which is made in the form a corner and a two-stage curved plate connected by a rectangular plate, and the frames are made with sockets located in the corners of the frame.

The device can be made with the possibility of regulating the length of the jumper and plastic.

The invention is illustrated by drawings, where in Fig.1 shows a non-supporting and non-removable frame, General view, Fig.2 - a plastic frame with slots for locks, Fig.3-5 - the location and configuration of sockets for locks and locks, Fig.6 and 7 - assembly of the cell by locking the jumper lock in the socket of the frame, Fig. 8 - jumper assembly with cover plate, Fig. 9 - section B-B of the jumper assembly, Fig. 10 and 11 - jumper and its section A- And, in Fig.12 - pad.

The method of erecting load-bearing walls is carried out by pouring into the assembled frame with communications installed inside it along its perimeter of lightweight porous concrete with a density of 150 to 1200 kg / m ³ from the pouring hose connected to the installation for its production at a speed depending on the performance of the installation. After pouring, the porous concrete is aged in the device for implementing the method until it is completely hardened, its specific density after hardening must correspond to the design. The lattice spatial frame can be made of various light materials, for example, wooden battens.

A preferred embodiment of the device for implementing the method of erecting load-bearing walls is a universal frame with jumpers 1 and frames 2 with sockets. The frame is sheathed with outer and inner skins 3, 4, made, for example, from drywall or plywood. The frame includes cells, each of which is assembled from two frames 2 and 4 jumpers 1 by locking the locks 5 in the sockets of the frames 2 located at the four corners of the cell. Locks 5 are made in the form of a corner and a two-stage curved plate connected by a rectangular plate. Frames 2 are made with sockets located in its corners.

The following frame-forming elements are extended to the first cell from above and from the side, using jumpers 1 with locks 5, to obtain the specified geometric dimensions of the wall with a length "L" and a height of "H". The casing 3 can be fixed to the frame removable or non-removable. The jumper 1, if necessary, has an adjustable length "L", i.e. can be reduced in length by cutting and removing its middle part, and in the remaining parts, protrusions are made and connected by means of a lining 6 having grooves corresponding to the protrusions of the jumper 1. This design of the jumper 1 allows you to mount the frame of any length and use it for door and window openings.

An example implementation.

CJSC "Selena" in the village of Zarechye built a 3-storey cottage according to the proposed method of erecting load-bearing walls.

The walls were erected using a frame made of wood in the form of a spatial lattice structure with a cell size of 40 × 45 × 40 cm. All communications to the building were mounted in the spatial structure of the frame before pouring it with porous concrete. To prepare the mixture for pouring, the modernized Super-Mixer ST-10 was used, the productivity of which is 5 m ³ / hour. The mixture was supplied to the place of laying by a plastic sleeve. As starting materials for the mixture were used - river sand, Portland cement M-500, water and foam concentrate.

The density of the porous concrete used to build this cottage was 650 kg / m ³ in the dry state, and its compressive strength was 3.05-3.15 MPa.

The method of erecting walls and a device for its implementation will ensure the erection of load-bearing walls of porous concrete with the required strength in building conditions while increasing its reliability and reducing material costs through the use of porous concrete with a density of 150 to 1200 kg / m ³ , as well as due to creating a universal frame in the form of a spatial lattice structure.
