Abstract

The combined two-layer masonry consists of two layers of porous concrete blocks. Concrete blocks have different densities. The two layers of masonry are interconnected by corrosion-resistant basalt (fiberglass) mortgages.

Description

The utility model belongs to the field of architectural and structural design.

There are well-known methods of two-layer masonry of walls using large-format blocks of porous concrete, where masonry is carried out by means of ligation of layers.

The closest to the declared technical solution is masonry with an intermediate connecting belt or layer binding; the technique of such masonry is described in publicly available sources, namely: - Manuals for the design of stone and reinforced stone structures to SNIP 1I-22-81; - Album of Technical Solutions of the XX Manufacturer Company (Vylegzhanina V.P., Pynsker V.P.) 2009; - Typical Nodes Series B2.000-3.07 Nodes and details of connections of structural elements of buildings "Minskproekt" 2007; - STO NAAG 3.1-2013 "Constructions using autoclaved aerated concrete in the construction of buildings and structures", Moscow 2013.

The disadvantages of this design solution are through seams, as well as the impossibility of the combined use of concrete of different densities to achieve the maximum level of thermal conductivity while maintaining high load-bearing capacity.

The purpose of the useful model is to increase the energy efficiency of the housing stock, reduce labor costs when erecting walls with a thickness of more than 400 mm, increase the level of structural properties of walls using porous concrete without increasing the cost of the finished structure.

This task is solved by using a combined two-layer masonry, which consists of two layers of porous concrete blocks of different densities, the layers of the masonry are connected to each other with the help of corrosion-resistant basalt (fiberglass) mortars, there are no ties between the layers of the masonry blocks.

Such a technical solution will avoid losses due to thermal heterogeneity of the walls, the load-bearing capacity of such masonry is not inferior to single-layer masonry, while the highest thermal conductivity result is achieved.

The principle of installation and advantages: in this case, lightweight concrete blocks with dimensions of 300 x 200 x 600 and 375 x 200 x 600 with a density of brands DZO0O - D5O0 (300-500 kg / m3) are used.

The construction of rows is carried out with an offset relative to each other. At the same time, all vertical and

The horizontal seams are covered with aerated concrete blocks. Even if there are thick enough masonry seams, there are no "cold bridges" in the masonry from the outer wall. The labor intensity of this installation process is lower than the labor intensity of the construction process of single-row masonry with a width of 500 mm. At the same time, the building volume of the blocks is similar to the version of single-row masonry.

The scheme of laying two-layer blocks of different densities without through seams with the use of corrosion-resistant basalt (fiberglass) floor coverings is shown in Fig. 1 - section of the masonry, where: 1 - blocks of different density 2 - corrosion-resistant basalt (fiberglass) masonry;

Fig. 2 - general view of the combined two-layer masonry.

This solution allows you to save time for the construction of buildings and structures, using two-layer combined masonry, no additional costs are required for insulation and sound insulation of external walls.
