Description

OOAKTYPEIfflOE BUILDING Utility model relates to building materials and may be

used in capital construction for cladding and thermal insulation of walls of buildings, structures.

Known building product for facing buildings made

by molding in the form of a panel containing a heat-insulating layer connected to a facing made using cement and sand. This layer contains reinforcement passing through the heat-insulating layer, with outlets from it located in pairs at different levels with an offset of the masonry step of the building material. The panel contains at least one end protrusion and a corresponding cavity located on the opposite end, while the thickness of the protrusion is greater than or equal to the width of the cavity. In addition, the product provides an option 1I5 | panels with two

ledges placed on mutually perpendicular ends, and on the opposite to them - the corresponding hollows. (Utility model No. 10197; M.cl. E04C2 / 26; 1998).

However, the use of a known building product for cladding structures is limited to structures erected by the masonry method, due to its design. The fastening of products to each other without additional termination of its outlets in the masonry of the structure is reliable provided that small-sized products are used, which, according to the laid design, cannot meet the standards of thermal insulation and weather resistance adopted by the regulatory documents of the Russian Federation for such products. In addition, the specified design of the connection "protrusion-cavity and placing it on two mutually perpendicular ends complicates the installation of products, lengthens the installation time of products, especially large ones, which increases the complexity and cost of construction. The absence in the material of the finishing layer of pigment and modifying additives, decorative fillers reduces the weather resistance and decorativeness of the product.

The proposed off-building construction product allows us to expand its range and industrial use.

The essence of the utility model lies in the fact that in the off-structured building product, made by molding using a mineral binder, including a heat-insulating layer, seamlessly connected to the finish, equipped with fittings that enter the outlets into the heat-insulating layer, and also having end protrusions and corresponding cavities parallel to them finishing layer, the thickness of the latter is less than or equal to / th the thickness of the insulating layer and

the invoice is made smooth or embossed from the molding mixture, in which pigment and modifying additives, decorative aggregates are used, while the reinforcement is placed at least 10 mm from the lower point of the relief, and the end protrusions, as well as their corresponding depressions, are on one surfaces parallel to each other and have a thickness less than the width of the cavity with a gap in the connection "protrusion-cavity in the range of 0.2-0.5 mm

The essence of the proposed utility model is illustrated by the drawing, where in FIG. 1 shows a general view of an off-structural building product; FIG. 2, 3 - options for placing the finishing layer on the product.

An off-structured building product, made by forming, contains a heat-insulating layer 1, (Fig. 1,2,3) monolithically connected to the finishing layer 2, in which reinforcement 3 is placed at least 10 mm from its surface, and its outlets are included in the heat-insulating layer 1, their length is less than its thickness by 20-5-50 mm. The thickness of the finishing layer 2 is less than or equal to the thickness of the insulating layer,

which is more than 30 mm.

On one end of the product protrusions 4 are placed (Figs. 1,2,3) and on the opposite end there are depressions 5 corresponding to them, parallel to each other and to the finishing layer 2. They can be made in the form of a semicircle, rectangle, trapezoid, triangle. The clearance in the protrusion-cavity connection is 0.2-gO, 5 mm.

ZOOM 5

The off-structured building product is made using a mineral binder, such as Portland cement, slag cement, caustic magnesite, etc. In the molding mixture of the finishing layer 2, heavy concrete is used with the addition of pigment and modifying additives, decorative aggregates. As the material of the heat-insulating layer 1, structurally-insulating cellular concrete, expanded clay concrete, wood concrete, and others are used.

An off-structured building product may have a finishing layer 2 (FIG. 3) placed perpendicularly to the end protrusions 4 and depressions 5 for facing the corners of structures, while the outlets of the reinforcement 3 of both layers in the heat-insulating layer are offset relative to each other. The texture of these layers is identical.

In the event that the invoiced building product used in the construction forms the inner wall of the structure with an unbroken end, it may also have a finishing layer 2 (Fig. 2), 10-20 mm thick, parallel to the end protrusions 4 and depressions 5. This layer is made along the texture is smooth, and lightweight concrete is used as the material.

Off-structured building product is used in the construction of lightly loaded, non-bearing walls of buildings, structures. The design of the product, the materials used, the thickness of the finishing layer 2 and the dimensions of the heat-insulating 1 satisfy the requirements of the standards for decorative and

thermal insulation products, as well as weather resistance and

thermal insulation.

Proposed design features of an invoiced building product

can be used in the manufacture of widely used in modern

the construction of blocks of cellular concrete wall small in accordance with GOST 21520-89.

Product manufacturing accuracy and texture of the front surface of the finishing layer

provided by the form used.

So, for example, a type IV block with standard dimensions of 198 x 195 x 398 mm, in which the heat-insulating layer is made of structural concrete heat-insulating foam, and the facing layer is made of heavy concrete with modifiers based on cement grade M500 ... M800, has the following indicators: 3 Suggested compared with the well-known construction product for facing buildings, an off-structured building product allows us to expand the range and industrial use of the product due to the design features of the product and the variety of texture of the facings LfTetanus layer. The design and materials used increase the atmospheric resistance and thermal insulation properties of the product, satisfy the requirements of current standards. This allows the product to be widely used in modern construction using advanced technologies, including monolithic. According to its strength characteristics, it is applicable for the construction of lightly loaded, curtain walls, convenient for installation, stable, decorative. This reduces labor and construction costs. % (S / M 134
