Description

The utility model relates to the construction of engineering protection to prevent the negative impact of water (hydraulic engineering).

Flexible concrete slab (GB-slab) (Fig. 1) is a set of concrete blocks (Fig. 1, position 1), interconnected by a flexible connection (AC 251463) (Fig. 2, position 2). Thus, in general, a GB plate is a structure containing the following essential features:

1. Concrete blocks, mainly two rectangular truncated pyramids having a common larger base, ensure the safety of the protected object;

2. Flexible connection, made mainly from the synthetic rope monolithic in the body of each concrete block - provides the connection of concrete blocks into a single structure;

3. Mounting loops (patent RU No. 23225474) (Fig. 1, position 3) - provide a hook with a hook of the lifting mechanism.

The weak link of the GB-plates of this design during operation, for example, when protecting the coast, is a flexible connection made of a synthetic rope (Fig. 2, position 2). Laying of a synthetic rope in a GB-plate is shown in figure 2. As a result of criminal damage, representing a cut flexible connections, theft of concrete blocks is possible. The result of this is the destruction of the protection of the object as a whole.

The synthetic rope (Fig. 2, position 2) in the GB-plate is laid in one piece, respectively, mounting loops (Fig. 1, position 3) are an integral part of flexible communication. Replacing a synthetic rope with a metal cable is not desirable and can lead to negative results. The cable must have sufficient elasticity to create a flexible loop; otherwise, a large gap will form between the concrete blocks of adjacent GB-slabs, which leads to the washing out of the ground of the protected surface. An elastic metal cable of small diameter does not have the necessary strength, and also pull in concrete blocks. A large diameter cable does not have sufficient elasticity.

Thus, the objective of this utility model (technical result) is to change the design of the flexible connection of concrete blocks, so that:

- she was protected from external damage;

- was elastic;

- possessed the necessary strength.

The solution to this problem is achieved by placing anti-vandal inserts along the synthetic rope (Fig. 2, position 4), which are segments of a metal cable.

The technical result is achieved by a combination of the following features of a utility model:

a) The restrictive signs characterizing the GB plate (generic term):

- concrete blocks;

- flexible communication;

- mounting loops.

b) A distinctive feature aimed at achieving the claimed technical result:

- anti-vandal inserts are pieces of metal cable (Fig. 2, position 4).

Anti-vandal inserts can have a corrosion-resistant coating in the form of galvanizing or synthetic coating.

When concreting GB-slabs in a forming tooling after laying a synthetic rope, pieces of anti-vandal inserts are laid (Fig. 2, position 4). Thus, the GB-plate has elastic loops (Fig. 1, position 3) and is protected from criminal damage.

Claims (3)

1. A flexible concrete slab, including concrete blocks interconnected by a flexible connection, and mounting loops, characterized in that metal flexible elements are placed along with the connecting reinforcing rope. 2. The plate according to claim 1, characterized in that the metal flexible elements are pieces of cable. 3. The plate according to claim 2, characterized in that the metal flexible elements have an anti-corrosion coating in the form of galvanizing or synthetic coating.
