KR20060115360A - Mobile munition container and mobile bunker or shelter and method and use of a reinforcing mat for producing said containers and bunkers (shelters) - Google Patents

Abstract

The invention relates to the use of a reinforcing mat for producing a mobile, preferably circular munition container, bunker or shelter. Said reinforcing mat comprises a plurality, preferably at least ten, spaced- apart fabric layers that are formed by fabric strands. The fabric layers are configured and disposed in such a manner that the mesh size or aperture width of the fabric layers varies across the reinforcing mat thickness to such an extent that, when cement mortar or concrete infiltrate the fabric a sieving effect is achieved, thereby fixating concrete aggregate grains of varying sizes in substantially defined layers across the reinforcing mat thickness ordered according to size.

Description

MOBILE MUNITION CONTAINER AND MOBILE BUNKER OR SHELTER AND METHOD AND USE OF A REINFORCING MAT FOR PRODUCING SAID CONTAINERS AND BUNKERS (SHELTERS) )}

For the purpose of explosion protection, mobile ammunition containers are generally made of steel, metal alloys or metals.

Fixed ammunition dumps made of concrete are known from WO 99/42678. If a static load is applied by internal pressure until the steel container ruptures, numerous fragments are generated. Container cracks in the weakest part are mostly formed along the weld line. However, if the container is subjected to a high dynamic load by the explosive explosion inside the container, the container is shattered into numerous fine pieces. The same phenomenon is observed for concrete. Parts made from prestressed and reinforced concrete under the stress of an explosion generally produce a fracture response of the part without considering its thickness. The fragmentation above and in excess of the blast wave is indicative of intrinsic hazard potential. Shattered concrete fragments are transformed into similar quasi fragmentation projectiles in the surrounding area by released explosive waves.

It is an object of the present invention to provide a relatively thin walled ammunition container made of concrete which provides effective protection in the event of explosives exploding inside the container.

It is a further object of the present invention to provide a relatively thin wall mobile bunker or shelter which is effectively protected against forces generated from explosions or impacts acting on the outer wall.

Particularly safe ammunition containers and / or bunkers or shelters are produced by use for the production of reinforcing mats described in WO 01/23685 having at least 10 spaced apart fabric layers made from ropes, the fabric layers being There is a change in the mesh and / or hole width of the fabric layer relative to the thickness of the reinforcing mat so that a screen effect can be obtained when the cement mortar or concrete penetrates, thereby varying the size. The concrete aggregate particles are fixed in size in predetermined layers for the reinforcing mat thickness.

It is preferred to use reinforcing mats for the production of ammunition containers and / or bunkers or shelters made of concrete according to the invention, with displacement bodies being located between adjacent layers of the fabric layers, each of which has a rope element ( When bundled at a right angle to each other by a cording element, it has the function of a spacer to adjust the rigidity.

With the use of the reinforcement mat according to the invention for producing a mobile ammunition container, the explosion protection is noticeably increased when the fabric layer is arranged with the mesh of the fabric layer increasing from the outside of the container to the inside. In this method, since the blocking effect of concrete aggregate and / or concrete aggregate particles occurs, relatively large aggregate particles are located in the outer wall area. The resistance to any compressive forces generated by the placement of large aggregate particles in the interior wall area is increased, which has a positive effect on the cylindrical ammunition container, the largest compressive force inside the container during explosion. This is effective.

The mesh width of the fabric layer is formed to increase from inside to outside in order to produce bunkers and / or shelters from which forces from the outside resulting from an explosion or impact act.

The blocking effect is achieved by changing the mesh width or by deliberately offsetting the fabric layers, each having the same mesh width and arranged in layers or side by side. The wall structure may be formed of a single layer, multiple layers or multiple shells.

Movable cylindrical ammunition containers and / or bunker twist shelters made of concrete comprise a plurality of fabric layers in the form of welded grating layers having a cylinder wall width of 5 to 60 mm and a wire size of 0.5 to 3.5 mm. It is characterized by having a reinforcement. This reinforcement is described as a micro-reinforcement.

The micro-reinforced high strength concrete is then used to make containers and / or bunkers or shelters with a relatively thin wall structure having a minimum wall thickness of approximately 40 mm that can be used as mobile ammunition or explosive containers and / or bunkers or shelters. .

According to the invention, the container and / or bunker or shelter can be molded monolithically, ie in a single part, or a cylinder segment having the advantages of a relatively light weight of parts for a manual transport device and / or assembly. It can be prepared as.

Containers and / or bunkers or shelters are preferably provided with concrete parts configured as sliding doors having the same structure as the left walls. According to the invention, the part formed by the door, ie the circular arc part, is the actual door opening such that the bracing of the door during explosion is formed by the force of pressing the door against the container inner wall and / or the bunker outer wall. Greater than

Ammunition containers are preferably equipped with lids having substantially the same reinforcing mat structure, such as container cylinders. In the event of an explosion the lid is fixed to the container so that the lid is folded and opened, thereby forming a predetermined breaking point.

A further variant consists of a lid having a pressure relief opening that is firmly fixed to the container. The top of the container has the shape of a truncated cone.

According to the invention, the ammunition container is described in detail below with reference to the drawings, in which a bunker or shelter of modified structure is applied.
