Abstract

FIELD: construction.

SUBSTANCE: invention relates to erection of walls of low-rise buildings. Method for erection of walls of low-rise buildings includes manufacturing foam concrete sections for outer surface of walls with facing layer of corrugated or other facing material and inner surface of walls with facing layer of gypsum board, wall by placing sections on foundation or underlying section to form a gap between sections filled after formation of group of sections along whole perimeter of building with material, capable of filling formed gaps and providing a monolithic connection thereof, wherein sections of outer and inner wall surface are joined together by a wire mesh screen.

EFFECT: reduction of labour intensity of erection of walls of buildings.

Description

1 area of use

The following wall manufacturing technology is proposed for use in both housing and civil engineering for the construction of walls of low-rise (up to 3 floors) buildings.

2. The technical level in construction during the erection of walls of buildings

Currently, the manufacture of walls of low-rise (up to 3 floors) buildings is carried out according to the following technology:

2.1 the walls of the building are formed on the foundation. In this case, various options are used:

2.1.1 brick

2.1.2 various blocks (expanded clay concrete, foam blocks, gas blocks, silicate blocks and other block modifications)

2.1.3 reinforced concrete panels

2.1.4 piloles

After the construction of the building, finishing work is carried out on the external and internal surfaces of the walls.

3. Description of the proposed technology for the manufacture of walls of buildings

The proposed technology for the manufacture of walls provides the following:

3.1 pre-manufactured elements (sections) with facing the outer surface of the future wall with facing materials (corrugated board, ceramic tiles, etc.)

The sections are manufactured using foam concrete as a binding-forming material.

It is possible to install reinforcing elements inside the foam concrete (steel, plastic rods filled with material that creates a pressure inside them above atmospheric, etc.)

3.2 pre-manufactured elements (sections) of the inner surface of the future wall with the lining of the outer surface of the section with drywall.

The sections are made of foam concrete similar to paragraph 3.1

3.3, the sections of the external and internal surface of the wall are mounted on the foundation or subordinate section.

At the same time, a gap of 3 cm or more is left between the outer surface section and the inner surface section of the formed wall.

3.4 sections of the outer and inner surfaces of the formed wall are fastened together by a masonry mesh made of wire VR-1

3.5 after the formation of a row around the entire perimeter of the building, foam concrete (polyurethane foam, etc.) is fed into the left gap, which fills not only this gap, but also intersection joints. (it is possible to form several rows with subsequent pouring with foam concrete (polyurethane foam)

To reduce the likelihood of the presence of empty spaces when filling with foam concrete, it is possible to use platform vibrators.

3.6 after the formation of the wall to the desired height, an interfloor overlap is laid on it, and then the next floor is likewise formed.

4. The difference between the proposed technology for the manufacture of walls from the analogue.

As an analogue, the technology of manufacturing the building envelope, described in patent RU 2285093 C1 of 10.10.2006, was taken.

The technology described in the analogue provides the following sequence:

4.1 the construction of the building according to the technology of frame-monolithic housing construction

4.2 a metal frame of corners and reinforcement is installed on the finished structure

4.3 enclosing wall structures are installed on the metal frame

4.4 in the gaps between the elements of the building, erected according to the technology of frame-monolithic housing construction, and mounted wall fencing, a solution is supplied (polyurethane foam, foam insulation, etc.)

The proposed technology provides the following sequence:

1. in workshop conditions, sections of the outer surface of the wall are lined with corrugated board.

2. in workshop conditions, sections of the inner surface of the wall are lined with plasterboard.

3. during the construction of the wall of the building, the installation of external and internal sections with a gap both between them and between individual sections is performed.

4. the outer and inner sections are fastened together by a masonry mesh made of wire VR-1. (the masonry mesh during the operation of the building will carry the vertical load acting on the wall to adjacent sections of the wall)

5. after the formation of a series of walls around the entire perimeter of the building (several rows can be formed), the gaps left are filled with foam concrete, or polyurethane foam, or other material that ensures filling of the gaps or under pressure of the incoming material, or by expanding the material entering the gap that can fill the gaps

At the same time, the requirements for personnel performing work are significantly reduced, since the material filling the gaps itself seeks to fill the voids.

6. Range of application of the proposed technology

The above technology is proposed to be used in residential and civil construction of low-rise (up to 3 floors) buildings.
