Description

The utility model relates to the field of construction, namely, to the designs of prefabricated blocks made in the form of heat-insulating panels for facing the external, preferably facade, surface of buildings and structures.

A known design of the panel for facing buildings or structures, containing a sheet of silicate glass, to the back surface of which are attached, for example, with an adhesive composition, anchors, while the longitudinal axis of the anchors are located at a distance not less than three diameters of the anchor rod, and from each other at a distance not more than the sum of the lengths of the pair of adjacent anchors (RU No. 31511 U1, 2003).

Such a panel design requires additional technological operations for a comprehensive solution of the building cladding issue during their reconstruction or construction.

Known wall panel for facing building structures (RF patent for the invention RU No. 2275480 C1, publication date: 2006.04.27), which includes a sheet of silicate glass or porcelain tile placed from its front surface, preferably with a decorative finish, to the back of which adhesive layer through a reinforcing mesh attached a layer of heat-insulating material, preferably foam glass or foamed closed-cell polymer material obtained by extrusion, for example polyurethane foam ana or expanded polystyrene, and made in the form of blocks arranged in rows, united by an reinforcing mesh attached by means of an adhesive composition over them. Moreover, the panel has at least four anchors connected to a sheet of silicate glass or porcelain stoneware, or with a reinforcing mesh, and / or with the main and / or additional layers of blocks. The main and additional blocks are laid with dressing of the seams, and the joints between their ends are filled with an adhesive or adhesive composition.

The disadvantages of this design is the complexity of the design, and also this design requires additional technological operations for a comprehensive solution of the cladding of buildings during their reconstruction or construction.

Closest to the claimed is a wall panel according to the patent of the Russian Federation for utility model No. 70675 U1, publ. 2008.02.10. The wall panel includes a facade surface, which is a layer of cement mortar, and insulation. The insulation is a plate made of extruded or foamed polystyrene, on which transverse grooves in the form of a dovetail are applied. Rectangular cross-shaped grooves are applied to the insulation, rectangular grooves are applied to the long ends of the insulation from expanded polystyrene. The layer of cement mortar is evenly distributed over the entire surface of the insulation. Dovetail grooves are filled with cement mortar. The wall panel has two holes for attaching the panel to the wall, into which mushroom-shaped bushings are inserted.

Signs that distinguish the claimed utility model from the prototype, are absent in the analogues.

The technical task of this utility model is to create a simple structure that provides the necessary strength and ease of installation on a building or structure and has good decorative properties.

This goal is achieved in that the thermal facade polystyrene foam block includes a facade surface, which is a decorative sand-cement layer reinforced with a fiberglass mesh, and a heater. The block is equipped with galvanized metal strips located in the cement-sand layer, and protruding above and below the boundaries of the block. Galvanized metal strips are curved in the form of a bracket and are intended for fixing the unit to the wall. This gives the unit additional strength when it is attached to the wall and does not damage the external decorative surface.

The inventive utility model is illustrated by drawings.

In Fig.1 shows a block thermal facade polystyrene with reinforced cement cladding layer, front view, Fig.2 shows a section aa, figure 3 shows a section bb.

The heat-insulated polystyrene foam block with an cement-cement facing layer consists of a heater 1 and a decorative sand-cement layer 2. The heater 1 is a 50 mm thick extruded or expanded polystyrene plate. The heater has a combustibility class G-1 (self-extinguishing). The thermal facade polystyrene block with an cement-cement facing layer with a foam polystyrene insulation is intended for use on building walls. The heat-facade polystyrene foam block with an cement-cement facing layer with an extrusion polystyrene insulation is intended for use on the basement of buildings. Transverse grooves 3 in the form of a dovetail are applied to the insulation. Decorative sand-cement layer 2 is adjacent to the insulation layer 1. The grooves 3 are filled with sand-cement mortar. In the heat-expanded polystyrene foam block with reinforced-cement cladding layer in the sand-cement layer 2, two metal galvanized strips 4 are installed. The metal galvanized strips 4 are intended for installation of the block without violating the texture of the decorative sand-cement layer. Galvanized metal strips 4 are curved in the form of a bracket. The ends of the plates 4 protrude beyond the boundaries of the block above and below. Mounting holes 5 are made at the ends of the galvanized metal strips 4, protruding from the top of the heat facade block. The heat-resistant foam polystyrene block with an cement-cement facing layer is additionally reinforced with a fiberglass 6. The reinforcing fiberglass 6 is located in the sand-cement layer 2.

Block thermal facade polystyrene foam with an armored cement cladding layer is made as follows.

The shape in the form of a trough, in which the heat-facade block is made, has a bottom, the inner surface of which corresponds to the shape of the external surface of the heat-facade block from a decorative sand-cement layer and imitates various textures - natural stone, granite layers, cobblestone, sandstone, etc. Galvanized metal strips with a width of 40 mm are laid in the mold at equal distances from the edges and mounted on a vibrating table. Prepare a sand-cement mortar. Lay out the solution in the form on a galvanized metal strip. Under the influence of vibration, the solution is evenly distributed in the form so that the metal strips are in the sand-cement mortar. Then, a reinforcing mesh 5 is placed in the solution. Extrusion or foamed polystyrene (insulation) is a 50 mm thick plate. Transverse grooves 3 in the form of a "dovetail" are applied to the plate. Insulation prepared in this way is put into a mold on a sand-cement mortar and pressure is applied. As a result, the solution fills the grooves in the form of a dovetail. Then the forms are placed on a pallet and placed in a steaming chamber. The heat-facade polystyrene foam block with an cement-cement facing layer lasts for 1-2 days in molds. At the same time, the decorative surface takes on a relief shape and can imitate various textures - natural stone, granite layers, cobblestones, sandstone, etc., as well as a smooth, smooth, non-textured surface. The surface of the cement layer can be painted in various colors.

The thermoformed polystyrene foam block with an cement-cement facing layer is taken out of the mold and laid out on the shelving for ripening.

Installation of blocks is made from below in a checkerboard pattern. The upper ends of the strips 4 are fixed to the wall. When installing the next row of blocks, the lower protruding ends of the strips 4 are led behind the lower block. The upper protruding ends of the strips 4 are attached to the wall. Then the process is repeated.

The heat-facade polystyrene foam block with an cement-cement facing layer can be manufactured on existing equipment with available technical means.
