Abstract

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to insulation and protection of external walls of residential and industrial buildings against precipitation. The method consists in the installation of thermal insulation panels on the wall, characterised by the fact that the double-layer insulation is produced of composite sandwich panels, mainly with polystyrene insulation and inserts, basalt stone, made in the factory, which is fixed on the surface of the wall anchors or self-tapping screws, joints between combined with sandwich panels are foamed, on the joints and edges of sandwich panels there are flashings installed using the sealant.

EFFECT: insulation and protection from precipitation for exterior walls of residential and industrial buildings and structures, simple installation works for new construction and for insulation and protection of buildings and facilities operated, easy replacement of an insulation facade after the end of life, an insulated facade may be mounted in any climate conditions and temperature conditions at both high and very low temperatures; work done without scaffolding.

Description

The invention relates to the field of construction, and in particular to a method of insulation and protection against atmospheric precipitation of the outer walls of residential and industrial buildings and structures.

A known method of external insulation of the facade of the building (patent RU (11) 2171340 (57)).

The technical result of the invention is to reduce the delamination of the insulation system. The method of external insulation of the building facade, including gluing insulation on the building facade, mechanically fixing it, impregnating the fixed insulation with a water dispersion primer to a depth of 2-8 mm, laying a reinforcing mesh and fixing it with adhesive composition. For the impregnation of the insulation, it is preferable to use a water-dispersed acrylic primer, and the reinforcing mesh is fixed with a cement-based adhesive based on acrylic resin. The disadvantages of this technical solution are the significant complexity, busyness, short service life of the outer decorative coating and the inability to work in cold weather. The closest technical solution to the claimed is the "Method of insulation of the outer walls of buildings and structures, insulated outer wall of the building and structures" (Patent of the Russian Federation RU 2112114).

The method of warming the outer walls consists in gluing a heat-insulating block to the wall and then applying it on the outer surface and on the anchors of the shotcrete-concrete layer. As a heat-insulating block, the Radoslav block is used with a self-extinguishing polystyrene foam insulated in a steel frame. Before installing the block, the wall surface is wiped with a hardening mortar, then a strip of continuous adhesive layer is applied along the block surface contour and the block is pressed against the wall in the working position, while passing the anchor through the block frame and fixing the reinforcing mesh on them from the block surface, onto which is sprayed with a concrete protective layer over the entire open surface of the heat-insulating block. The thickness of the shotcrete-concrete layer is 1 / 1.2-1 / 7 of the thickness of the heat-insulating block

The disadvantages of this technical solution are the significant complexity, the inability to work in cold weather on a new building and the difficulty of warming the outer wall during repair.

The new technical solution is aimed at creating a method of insulation and protection against atmospheric precipitation of the outer walls of residential and industrial buildings and structures, ensuring ease of installation work in new construction and replacing the insulation of the facade after the end of its operation, the possibility of year-round production work, cheaper construction and repair work, increase the life of buildings and structures due to the durability of the materials used in the insulation elements.

The method of insulation and protection against atmospheric precipitation of the external walls of residential and industrial buildings and structures, which consists in installing insulation panels on the wall, characterized in that the insulation is performed by simple or combined two-layer sandwich panels (1), mainly with polystyrene foam insulation (2) with inserts from a basalt plate (3) factory-made. which are fixed to the wall surface (4) with anchors or self-tapping screws (5), the joints (6) between the sandwich panels are filled with foam (7), at the joints and the ends of the sandwich panels install additional elements (8) on the sealant (9). The method of insulation and protection of facades consists in mounting on the walls of buildings and structures (4) two-layer continuous or combined sandwich panels (1), manufactured in the factory. When installing sandwich panels, standard fasteners (anchors, or self-tapping screws-5) are used, joints are foamed with mounting foam (7), additional elements (8) are fixed to sealant (9). Installation work is carried out from the cradle; lifting the sandwich panels is done by the winch from the cradle. Installation work is carried out according to construction drawings and diagrams. The thickness of the insulation is selected based on the heat engineering calculation. The number and type of fasteners is determined depending on the length of the sandwich panels.

The difference between the method of insulation and protection against atmospheric precipitation of the external walls of residential and industrial buildings and structures with two-layer continuous combined sandwich panels manufactured in the factory is the simplicity of installation work in new construction and the replacement of facade insulation after the end of its operation, the possibility of year-round production, cheaper construction and repair work; increase the life of buildings and structures due to the durability of the materials used in the insulation elements.

Depending on the qualifications of the installers, the work can be performed in one or two stages. The first stage is fixing on the wall (4) two-layer sandwich panels (1) with inserts from a basalt plate (3) with anchors (5) The second stage is sealing joints (6) between the horizontal panels with foam (7) and installing additional elements (8) on sealant (9). The proposed technical solution is justified by full-scale experimental tests.

The invention is illustrated in figure 1, where:

1 - two-layer sandwich panel

2 - polystyrene foam insulation

3 - inserts from a basalt plate

4 - wall

5 - anchor

6 - joints between horizontal panels, foamed with foam

7 - mounting foam

8 - additional elements

9 - sealant.
