Description

Technical field

The utility model relates to the field of construction, namely to the external thermal insulation of walls in the system of external insulation of facades, can be used for cladding with insulation of wall structures of both newly erected buildings and the reconstruction of dilapidated buildings and structures in housing, civil, industrial, agricultural, transport and other types of construction.

Molded plate for facade heat-insulating composite systems with external plaster layers (SFTK), is used for thermal protection of enclosing wall structures of buildings and structures for various purposes and the level of responsibility from the outside during new construction, reconstruction and overhaul.

State of the art

Known heat-insulating coating for wall cladding, including heat-insulating boards attached to the bearing wall of the building, covered on the outside with a protective layer of plaster, characterized in that the plates are attached with glue, while as heat-insulating boards used plates obtained from expanded perlite, the plates on the side of the protective layer have a patterned pattern (see RF patent No. 2208110, IPC EG4F 13/08, published 2003.05.20).

The difference of the proposed technical solution is the lack of reliability of fixation.

Known lining of the walls of buildings, carried out by means of plates containing an intermediate layer based on polymer cement glue, while silicate plates with a smooth, or rusticated, or chipped textured surface are used as plates, the heat-insulating element is additionally fastened with the help of dish-shaped dowels, on polymer cement glue (see RF patent No. 96384, IPC E04F 13/00, published 07/27/2010).

The disadvantage of the described analogue is the inconvenient and non-universal fastening of the structure to the wall of the building.

Heat-insulating coating for wall cladding, including heat-insulating boards attached to the load-bearing wall of the building, covered on the outside with a protective layer of plaster. The plates are attached to the wall with glue. Plates on the side of the protective layer may have a patterned pattern. As an adhesive layer, the coating may contain a cement-based adhesive. Cement-based plaster is offered as a protective layer. To increase the reliability of the heat-insulating coating in general and the protective layer in particular, a grid can be additionally laid under the protective layer of plaster, and heat-insulating plates can be additionally attached to the load-bearing wall using anchors (see RF patent No. 2235838, IPC E04F 13/08, published 09/10/2004 09/10/2004).

The difference of the proposed technical solution is also an unreliable fastening system

There is a heat-insulating panel made in the form of mats, a protective layer with a reinforcing mesh and anchor bearing elements. The mats are fixed to the wall with glue and anchors. At the free ends of the anchors, fixing elements are located, to which a reinforcing mesh with a protective layer made in the form of shotcrete or shotcrete-stucco coating is rigidly fixed. The mats are made in the form of heat-insulating plates, mainly polystyrene foam (see RF patent No. 2139980, MPK E04V 1/74, published 10/20/1999).

The difference from the proposed technical solution is also an unreliable fastening system.

The closest material taken as a prototype will be a panel for external insulation of the facade of the building, subsequently on which an additional layer of protective coating and / or finishing will be applied, containing a slab in the form of a parallelepiped of molded polystyrene foam, the front and back surfaces of the slab are made with a texture in the form of rhombuses , while on the front surface of the plate, there are markers for doweling, vertical and horizontal grooves to compensate for linear expansion, on the back surface there are markers for applying various types of glue and trapezoidal grooves to increase adhesion (see patent EP 2949827 A1 dated 02.12.2015 .).

The proposed design improves the prototype.

The proposed molded slab is a building element for facade heat-insulating and protective coating systems during the construction of new buildings and structures, as well as during the reconstruction of existing buildings and structures, namely for external thermal insulation with a thin layer of plaster over the insulation.

A molded plate was created in the form of a parallelepiped of molded polystyrene foam with side lengths of 600x1200 and thicknesses of 100, 120 and 150 mm, which has a diamond-shaped texture on the front and back surfaces of the plate to ensure greater adhesion. On the front surface of the slab, for reliable fastening to the outer wall, there are markers for doweling with a diameter of 50 mm; there are also vertical and horizontal grooves to compensate for linear expansion, combined with marking lines for cutting framing elements of window and door openings. On the back surface there are markers with a diameter of 100 mm in the form of curved strips for applying various types of glue and trapezoidal grooves to increase adhesion, while there is a beveled edge for excess glue. On the side surfaces along the long side there is the inscription WALL / WALL and two arrows to indicate the direction of installation.

The utility model is illustrated by an example of the implementation of a heat-insulating coating. The wall, if necessary, is cleaned of the old coating and primed. Glue is applied to the heat-insulating boards with a diamond-shaped texture for reliability. Plates are laid end to end to each other. At the same time, on the back surface of the plate there are also markers in the form of curved strips for applying various types of glue, trapezoidal ones to increase adhesion, and a beveled edge for excess glue. Next, the plates are pressed tightly against the wall. Holes are drilled in the wall and anchors are inserted in such a way that they fasten the heat-insulating boards to the wall with dowels, in the places marked with dowel markers. After the adhesive has cured, a protective layer of cement plaster is applied to the boards. At the same time, vertical and horizontal grooves are located on the front surface to compensate for linear expansion, combined with marking lines for cutting framing elements of window and door openings. This improves the ability to bear a layer of plaster for weather protection.

During installation, heat-insulating boards are positioned so that the wall is in the direction indicated by the arrows and the inscription WALL / WALL.

The claimed utility model provides an increase in the performance of heat-insulating plates, increases the external thermal insulation of buildings and structures, and meets modern requirements.

The analysis of patent and scientific and technical literature did not reveal technical solutions with a similar set of essential features, which allows us to conclude that the claimed utility model meets the criterion of "novelty".
