Self-supporting components for the production of bulletproof

Shelters

The present invention relates to a component for achieving effective protection against attacks from the air by means of weapons emitting targeted shots (armes d tir tendu). This protection should · also against all explosive projectiles and non-exploding projectiles of small or medium caliber, as well as against machine gun projectiles, Rifle bullets and bullets from Paustf euerwaff.en, as well as against the pressure and fragmentation effects of explosive ordnance that explodes in close proximity. In the end this protection should also be effective against the heat effects and pressure effects of a medium distance ensuing nuclear explosion.

009842/0102

The aim of the present invention is with The help of such easily demountable components and for a reasonable price an effective protection against the above To create projectiles offering device, however, with regard to the type of protection against the explosive projectiles is novel. This component can be z. B. use in the construction of aircraft hangars, or in the creation of every other shelter that one May be exposed to attack.

To this end, the present invention seeks a standard component with a double wall, which on the outside has a classic type of surface layer with little ballistic Resistance and depending on the intended conditions of use of variable thickness, which is carefully calculated so that the impact on impact across this first The detonation of a projectile following the wall only takes place behind this covering layer at a distance that is so created is that the splinters do limited damage to this wall at the speed they can achieve, and which component on the second wall, inwardly, a protective plate to hold the splinters open without damage has, which is arranged for this purpose at a distance from the first wall, which is a puncture of the The type of projectile, its explosive effect and the delay of its detonator is such that the splinters at cause limited damage to the speed they reach that wall.

This distance between the two walls also takes into account the delay of the detonator of explosive projectiles, usually soft for attacking lightweight structures Find use.

In one embodiment of the invention, there is the first wall forming and having a low ballistic resistance outer cover layer made of classic Building materials, such as B. flat, corrugated or pressed shapes having plates made of metal or plastic ,, ■■ · ...

These building materials can, if necessary, be subjected to treatments, or they can be given coatings or additives cause an improvement in their reflective, anti-corrosive, fireproof properties, as well as their resistance against normal or accidental loads and their impact resistance, and thereby the permeability for heat and radiations and the fragility are reduced. Plastic plastics in particular can be "reinforced by grids or fibers.

According to one embodiment of the invention, the protective plate forming the second wall is e.g. B. about a meter behind the first wall to protect against a 30 mm air-to-air projectile arranged. This second wall can, for example, be formed by a classic armor plate, the thickness of which is at Manganese steel can be of the order of about 5 mm, to provide protection against a 30 mm air-to-air projectile.

According to another embodiment of the invention Both walls are supported by a hollow, pyramid-shaped lightweight framework that can be joined and stacked is to create removable components that are lightweight assemble, dismantle and transport.

According to one embodiment of the invention, the two wall components are assembled so that they a building or

In particular, the assembly can be carried out in such a way that that beams are directly connected to each other, which enables the assembly of successive sections into one enable self-supporting construction.

According to another embodiment of the invention, the components for forming the self-supporting roof structure of a building or shelters can be used for protection to be used above.

According to a further embodiment of the invention, the components for producing the end wall are a Shelters · · or any part serving to protect this front wall, e.g. B. a door or a moving one Titflügels, whose lightness makes them easy to handle.

According to another embodiment of the invention has Each component has a teaching of half-timbered trusses, which is then clad on both of its walls and optionally with a fleece and a cladding of the <Protective plate is provided.

^; According to the invention, the inner protective wall is connected to the teaching by means of brackets, and the outer wall is attached to the other side of this teaching with the aid of any suitable means.

In Figures 1 and 2, a component 1 forms a side wall and a component 2 the roof, and both are designed according to the invention, i. H. they have one with fiberglass reinforced outer wall 3 made of plastic, which is 3 mm thick, and an inner wall, which is formed by a Fan plate 4> the 5 mm thick and 1 m behind the outer wall is arranged. The numbers listed are only examples.

The two walls are attached to lightweight supports, which are essentially formed by cross members 5, the are attached to bars 6 · A unit of two parallel bars with the two walls forms the component or the teaching·

In the exemplary embodiment under consideration, the component 1 forms an angle of 67 ° 30 * with the horizontal. It is on its outer surface is 5 m long and its inner surface is 4.170 m long. The component 2 forms with the horizontal an angle of 22 ° 30 '. It is 7.5 m on its outer surface long and 6.670 m long on its inner surface.

In this way a protected structure is obtained, the width of which on the ground is aw «i 2 χ 7.750 m = 15.560 m and its greatest internal height is 6.670 m.

Standard components of 5 m and 7.50 m in length, which are joined together in different ways, allow the formation of bridge girders of various shapes and dimensions.

With a sufficient number of bridge girders of the same shape, which are joined laterally,

- 7 -009842/0102

a hangar of any length can be formed.

One of the advantages of the component according to the invention is in that an explosive projectile (P), which is the first Wall 3 (Fig. 2) reached, this breaks through without leaving a trace in it other than the opening corresponding to its passage, but that the thickness of this Wall is such that the explosion of the projectile, which on the impact during the penetration of the Wall follows (point E), at a suitable distance follows, in such a way that the splinters take into account the detonator delay and speed of the projectile. after its explosion, the first wall, which has a low ballistic resistance, does not seriously damage it while the splinters are intercepted by the panther plate (second wall 4) without damage if the blast was dee Geeehloeee · «I would do the direct impact on this breading plate.

Plate so that it does not suffer from it. However, if the thickness were greater, the explosion would be very close instead of the plate, which means that it does not resist the explosion.

As already stated above, you can arrange a filling protective agent, which z. B. from a fleece can be formed with certain properties, such as a resistant grid visible in Fig. 2 In Fig. 2, the protection provided for the wall 4 is shown schematically, which has the shape of a ver - clothing 8 can have the desired properties (e.g. heat protection properties in the case of fire floors).

In the case of rifle projectiles or other penetrating projectiles that do not explode, the first wall has no special effect, and these projectiles are stopped by the protective plate in a known manner.

Figures 3, 4 and 5 relate to an embodiment with components of small dimensions, which can be easily transported to quickly equip new or removed support points.

In this embodiment, the side surfaces form a truncated pyramid in such a way that after removal of the outer wall, the inner wall and the veretrebungetravereen eioh the gauges in one another for stacking and for transport plug into each other, reducing the total volume permit.
