FR2619148A1 - CONCRETE BED PROTECTION (BPPB) - Google Patents

Abstract

The invention relates to the particular use of a suitable concrete for producing protective structures which allow shooting with handguns and long guns in complete safety for shooters and their environment. The concrete "absorbs" the bullets and stops them without ricochets, nor return and this even for a very closed angle of fire. We can use this concrete to make: walls, ceilings, floors of a shooting range; the walls of an evolution zone devoted to the full-scale training of special police and military intervention forces; sensitive parts of structures with a high risk of armed attack, bank, counter, bullet-proof glazing sill; the reinforcement of the frames by injecting them with bullet-proof concrete.

Description

The present invention relates to the particular use of a concrete

  propriety to make protective works that allow firing with ar-

  my fist and shoulder all calibres, safe for shooters and

their environment.

  Currently, the shooting stands, evolution area, wall of lighter under vi-

  bullet-proof rage, and bulletproof glazing frames are made in accordance with

  by materials related to their structure:

  Agglomerated minerals, wood veneer, metal reinforcement, Kevlar.

  This homogeneous concrete compound consists of expanded clay aggregates or

  expanded schists, galvanized or non-galvanized metal fibers depending on the

  whether or not outside, a conventional hydraulic cement, a plasticizer adJuvant. everything flows with formwork vibran: t without acute vibrarnte This concrete obeys the common rules for the manufacture of a concrete with

  lightweight aggregates with embedded metal fibers.

  The walls, floors, ceilings of the shooting stands made with the invention "absorb" balls and avoid ricochet projectiles and shine material. The balls do not go through the invention because they are braked

  fiber, which allows for the development of other activities without the risk of

the walls.

  The protective walls have sufficient mechanical characteristics to

  also serve as a structure of a building.

  FIG. 1 represents a shooting stand made with the invention (1), with

  various activities around - plan view -.

  Figure 2 shows a shooting stand made with the invention (1), with various activities around, more the invention also serves as a building structure. According to a variant, the invention can be used to make prefabricated plates in order to equip very quickly at a lower cost a room in a shooting range, or to reinforce the security of an existing stand whose coating is not

not satisfying.

  A zone of evolution is a large space in which really armed shooters operate (no firing simulation). The purpose of this installation

  is to train police or military intervention specialists in

  dragging in real size sets with real ammunition in real situation. To date, equipment of this type did not allow the use of all calibres, only the 22 long rifle was possible. Thanks to the invention

  the "actors" can train with weapons and ammunition

nels (9 mm, 5.56, 7.62).

  FIG. 4 represents an evolution zone made with the invention (1)

- sectional view -.

  According to a variant, if one wishes to have definitive decorations, these

  can be realized with the invention.

  According to another variant, the peripheral walls made with the invention

  can be used as a structure for other adjoining buildings.

  The spandrel walls beneath the bullet-proof glazings made with the invention protect the personnel and ensure the support of the structure by guaranteeing its stability.

  stability since there is no bursting under the impact of the projectiles.

  According to a variant, the invention can be used to make plates

  prefabricated, which will be doubled to the existing structure if

  It does not have enough qualities to stop the bullets.

  The injected bullet-proof glazing frames-with the invention, become

  are also bulletproof. We will take care to take a granulometry

  adapted to the inner section of the uprights.

  The cost will be much lower than metal reinforcements

  glass-resin composites, or keviar-based.
