RU2638757C2 - Detachable protective structure block - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: detachable protective structure contains the tongue-and-groove blocks of three parallelepipeds. Blocks consist of the hollow body, welded from flat and/or bent metal sheets without through welds, and the body filling. The body can be filled completely or partially with one or more fillers through the hole in the tongues. When using different fillers, each of the parallelepipeds may have the opening for the corresponding filler. Using of different fillers allows to create the multi-stage protection with different properties, taking into account interaction with the destructive agents due to changing its effect on the block elements.

EFFECT: detachable protective structure provides the reliable protection against bullets, from small-calibre projectiles and shell fragments.

Description

The invention relates to the military defense industry, in particular to defensive structures designed to protect military personnel, for example, at a checkpoint.

A wide variety of concrete blocks are known for the construction of various structures (see http://1001block.ru/).

The use of well-known concrete blocks for the construction of a collapsible protective defensive structure is unacceptable, because it requires a solution for connecting the blocks to each other, which eliminates the collapsibility of the structure and its quick-build, which is especially important in the case of military operations.

The use of large blocks stacked on top of each other without using mortars to form a protective structure is also unacceptable, because the use of such blocks without fitting to each other will lead to the formation of gaps (holes) and the structure will not fulfill its protective function.

The technical result to which the invention is directed is to eliminate the above-described disadvantages of the known building blocks.

The technical result is achieved by the fact that the block collapsible protective structure contains a tongue-and-groove hollow body, welded from flat and / or bent sheets of metal without through seams, and a filler or various fillers filling the case in whole or in part.

At least one filler can be made loose, while at least one sheet of material limiting the precipitation of the loose filler can be placed inside the housing.

The invention is illustrated by drawings.

In FIG. 1 shows a fragment of a collapsible protective structure; in FIG. 2 - tongue-and-groove block of three parallelepipeds.

Collapsible protective structure contains tongue-and-groove blocks 1 of three parallelepipeds 2, 3 and 4. Blocks 1 consist of a hollow body welded from flat and / or bent sheets of metal without through seams, and filling the body. The housing can be completely or partially filled with one or different fillers through the hole 5 in the ridge 6. When using different fillers, each of the parallelepipeds 2, 3 and 4 may have a hole for the corresponding filler.

The use of different fillers allows you to create multi-stage protection with different properties that take into account interaction with means of destruction as their impact on the elements of the block changes.

When using a bulk filler, such as sand, it is advisable to use a sheet (s) of material that limits the precipitation of bulk filler. The sheet (s) is also a filler and can be made of rubber or other material capable of tightening (reducing) the resulting hole after interacting with the means of destruction.

The blocks 1 are interconnected by metal plates 7 by screwing the fasteners 10 into the holes 8 of the plates 7 and into the holes 9 of the blocks 1. The holes 9 of the blocks 1 are not through and can be made at the place of assembly of the protective structure or during the production of blocks 1. All blocks 1 or some of them can be carried out with handles 11 for carrying. Handles 11 are made in the form of brackets welded to the metal cases of blocks 1.

The assembly process of the protective structure is as follows.

Blocks 1 are delivered to the place of assembly of the protective structure and are interconnected with the placement of the crests of the blocks in the corresponding grooves of adjacent blocks without the formation of holes (gaps) between them. Blocks 1 are interconnected by plates 7.

The collapsible protective structure provides reliable protection against bullets, from small-caliber shells and shell fragments, as has no through holes.

Claims (3)

Block collapsible protective structures containing a tongue-and-groove hollow body, welded from flat and / or bent sheets of metal without through seams, and a filler or various fillers that fill the case in whole or in part. 2. Block collapsible protective structures according to claim 1, characterized in that at least one filler is made loose. 3. Block collapsible protective structures according to claim 2, characterized in that at least one sheet of material limiting the precipitation of granular filler is placed inside the housing.
