Description

The utility model relates to the field of construction and can be used in the construction of curtain walls of buildings from large-size aerated concrete blocks.

Known laying of walls made of aerated concrete blocks with a thickness of one block -3 mm.

The disadvantage of the known masonry is the need for obligatory longitudinal dressing of the wall every 3-4 rows with reinforcement laid in strips, or with a metal mesh, which are temperature bridges.

Closest to the claimed technical solution, adopted as a prototype, is the laying of walls from aerated concrete blocks on polyurethane glue [AS Gorshkov, NI Vatin. Properties of wall structures made of autoclaved aerated concrete products on polyurethane glue // Engineering and Construction Journal, No. 5, 2013. P. 5-19], including a vertical row of blocks with longitudinal dressing of seams, made in the form of a thin layer of polyurethane glue.

The following set of prototype features coincides with the essential features of the utility model: one row of aerated concrete blocks with longitudinal dressing of the seams made in the form of a thin layer of polyurethane glue.

However, this closest to the claimed utility model, the laying of walls made of cellular concrete blocks on polyurethane glue is not effective enough, because polyurethane adhesive in masonry has low shear stiffness, reducing the crack resistance of the masonry.

The utility model is aimed at creating a rigid and crack-resistant masonry on polyurethane glue, providing high thermal uniformity.

This is achieved by the fact that the masonry of walls made of cellular concrete blocks with their fixation includes a vertical row of blocks with longitudinal dressing of the seams, made in the form of a thin layer of polyurethane glue. The proposed solution consists in the fact that each block is attached to the underlying row of blocks by two glass-composite rods 50 mm longer than the block height, driven into the block at a distance of 1/3 of the block length from its bonded sides.

The utility model is illustrated by a drawing, where FIG. 1 shows a general view of the masonry of walls made of cellular concrete blocks measuring 200 × 300 × 625 mm (STO NAAG 3.1-2013) with two glass-composite rods (GOST R 54923-2012) in each block, in Fig. 2 shows a longitudinal section of the wall masonry made of aerated concrete blocks measuring 200 × 300 × 625 mm along a glass-composite rod.

Wall masonry consists of cellular concrete blocks, interconnected with a thin layer of polyurethane glue (1). The block of the overlying row (2) of the masonry is attached to the blocks of the underlying row (3 and 4) with two glass-composite rods (5). The rods are driven into the block at a distance of 1/3 of the block length from its butt sides (Fig. 2). These rods, penetrating the block (2) along its entire height, are driven into the underlying blocks (3 and 4) to a depth of 50 mm (Fig. 2).

The use of glass-composite rods in a masonry made of aerated concrete blocks on polyurethane glue makes it possible to increase the rigidity and crack resistance of the masonry by increasing its shear stiffness in the seams, while ensuring high thermal engineering uniformity.

Claims (1)

Laying of walls made of cellular concrete blocks with their fixation, including a vertical row of blocks with longitudinal dressing of seams, made on a thin layer of polyurethane glue, characterized in that each block is attached to the underlying row of blocks with two glass composite rods 50 mm longer than the block height, driven into the block at a distance of 1/3 of the block length from its butt sides.
