Description

The invention relates to the construction, and in particular to the technology of construction of a multilayer wall of a building.

There is a method of erecting a multilayer wall of a building, when the outer panel is hung over the entire facade of the building using hooks on the eyes installed on the supporting structures of the building, then the inner wall is erected from lightweight masonry using small pieces of materials and as the masonry is completed, the space between the inner and outer walls is filled insulation. In this case, the panel is equipped with four fastening elements in the form of mounting hooks (see RU 2282697, E04B 2/26, 08/27/2006).

Known facade precast hinged panel, made in the form of a rectangular plate with embedded parts on the front surface (see RU 65918, E04C 2/06, 08/27/2007). Mounting hooks and consoles are made separately and welded to the plate by means of embedded parts immediately before installation. Mounting hooks are welded to the top of the plate, and the console to the bottom. Using lifting equipment, facade panels are hung in such a way that the mounting hooks fit into the holes of the eyes placed on the supporting elements of the building frame. Support consoles are installed on the support tables provided on the vertical or horizontal elements of the building frame. Then, wall masonry is carried out, for example, from small lightweight concrete or cellular concrete blocks, during which the space formed between the facade panel and the masonry is filled with thermal insulation.

The main disadvantage of the known solutions when using facade panels with plate heaters is the need to accurately cut holes in the insulation for mounting hooks and consoles, which is quite laborious to carry out, given that the work is carried out directly during the construction of the wall using most often improvised means. There are also difficulties in checking the quality of the thermal insulation device, since the masonry is carried out before installing the insulation layer.

The objective of the invention is to improve the quality of installation of thermal insulation during the construction of a multilayer wall of a building using facade panels and providing the possibility of its control.

To solve this problem, the method of erecting the outer wall of the building, including installing the outer and inner walls separated by an air gap and placing insulation between them, and first, complex facade panels are hung on the building frame, differs in that, after installing a complex facade panel with the main layer of tile insulation and before the construction of the inner wall of lightweight masonry using small pieces of materials, a second heat-insulating layer of the required thickness is installed. If the thermal insulation is combustible (groups G2-G4), then in the manufacture of an integrated facade panel, the dimensions of the insulation panel are taken smaller than the size of the facade panel. In the gap remaining after installation of the complex facade panels, a non-combustible (NG group) insulation is placed. The embedded part located in the lower middle part of the panel is welded with a steel rod to the embedded part in the foundation beam. Next, the steel rods are welded to the embedded parts of the panels (lower and ordinary panels have embedded parts in the lower and upper parts). After installation of the complex facade panel, a second layer of thermal insulation is laid. In this case, the total thickness of the insulation is taken equal to the design thickness of the insulation. Thermal insulation plates are fastened together using polymer connectors or glue. The space at the junction of the hook and loop is filled with fiberglass or foam. After performing the insulation work, the internal wall is laid out from small-piece materials (blocks or bricks). If necessary, before performing masonry work, a vapor barrier material is attached to the thermal insulation. Instead of masonry, a prefabricated option can be provided: installing a frame of steel profiles to the elements of the building frame and attaching cement-bonded particleboards, glass-magnesium sheets, etc. to them.

To implement the claimed technical solution, a comprehensive facade panel is used, consisting of a reinforced concrete facade plate with mounting hooks and the main layer of thermal insulation (see RU 108775, E04C 2/00, 09/27/2011). At the same time, the panel has embedded parts located in its upper and lower parts.

An essential sign is that after the panels are installed, the gaps between the insulation boards are filled with insulation and the second final insulation layer is attached to the insulation layer of the complex facade panels.

A comparative analysis of the characteristics of the claimed solution with the signs of analogues indicates the conformity of the claimed solution to the criterion of "novelty."

The combination of features of the invention provides a solution to the claimed technical problem, namely the manufacturability and efficiency of the installation of thermal insulation.

The method of erecting an external multilayer wall is illustrated by drawings, in which Fig. 1 shows a view of the wall from the side of the building’s interior after installation of complex facade panels and filling of gaps with non-combustible thermal insulation, and Fig. 2 is a fragment of a section of a multilayer wall of a building.

Symbols adopted in the drawings: 1 - an integrated facade panel with a main layer of thermal insulation (the edges of two keys protruding behind the insulation are shown); 2 - strips of non-combustible insulation; 3 - vertical elements of the frame; 4 - horizontal elements of the frame; 5 - eyes; 6 - an additional layer of non-combustible thermal insulation; 7 - fiberglass or mounting foam; 8 - vapor barrier; 9 - a masonry of small-piece elements; 10 - plaster.

The method is as follows. Complex facade panels with a layer of thermal insulation are hung by means of mounting hooks on the eyes 5, placed on the vertical 3 or horizontal 4 elements of the building frame. Steel rods are welded to the embedded parts of the panels (lower and ordinary panels have embedded parts in the lower and upper parts). In this way, hanging on the frame of the building alternately complex facade panels isolate the interior of the building from external influences. After installation of the complex facade panels with the main insulation layer attached, the second final insulation layer 6 is laid. 6. The plates of the second insulation layer are attached to the insulation of the complex facade panel using connectors or glue. The gap remaining around the perimeter of the main layer of heat-insulating plates is filled with strips of non-combustible insulation 2. The space at the junction of the hook and loop is filled with fiberglass or polyurethane foam 7. If necessary, a vapor barrier material is attached to the inner surface of the insulation 8. After that, it is flush with the inner surface of the insulation and flush with the edge of the overlap is masonry made of small piece stone materials (blocks or bricks) 9. A layer of plaster is applied to the masonry 10. For installation, approx. it provide for appropriate openings.

The advantages of the method are:

- manufacturability and quality assurance of thermal insulation laying;

- the exclusion of end-to-end joints in the insulation layer by shifting the main and second layers of insulation, thereby eliminating additional heat loss of the outer wall;

- providing the ability to control the quality of installation of thermal insulation.
