Definitions

  • the invention relates to a device for protecting (people and / or objects) against the effects of an explosion with a frame which carries at least two mutually opposite barriers.
  • a device for protecting (people and / or objects) against the effects of an explosion with a frame which carries at least two mutually opposite barriers.
  • the use of devices to protect against the effects of an explosion is known.
  • air-permeable explosive mats have long been used in quarries to dampen explosive effects. The formation of such mats resulted mainly from trial and error. Recently, such devices have also been considered useful in other commercial and military fields.
  • An explosion protection device has many important applications.
  • such a device can be used in traffic terminals, such as airports and bus stations, where terrorist attacks can be expected.
  • devices can take many forms.
  • such a device can be used at sites for checking luggage.
  • a Such a device can also be designed in such a way that it can be installed in an aircraft, so that any device in it can be sealed off until it is possible to clear it.
  • Larger devices of the type described can be used to provide protection where a larger shielding area is desired.
  • a larger shielding area can be desired.
  • such a device can be arranged around lockers or the like at an airport.
  • an explosive device can be surrounded by a device designed as a protective shield in order to protect the workers. If one wishes to protect a room from an explosion occurring outside the same, such a device can be reversed in function and form a control room in which people can be protected.
  • a device of the described construction and the intended purpose also has many military fields of application.
  • explosive devices can be stored in a shielded device designed as a container, or larger devices in the form of shields can be used to surround storage places for explosives.
  • the operation of the device can be increasingly reversed in military use to provide protection for the facility and personnel from explosive off-locks Creating detonations.
  • Such a protective barrier requires that the device be able to withstand not only high pressure waves and flames, but also high-speed splinters which are pieces or fragments of ammunition.
  • devices of the construction described are particularly desirable. This applies, for example, to the transport of dynamite and primers to the area of application. In this case, a device must be relatively small and lightweight.
  • Splinter protection walls made of concrete and steel shelters can provide sufficient protection, but are bulky and too heavy to meet the requirements of the various aforementioned applications. Splinter protection walls often block the movements of people and machines due to their large size. Devices constructed in this way are also not transportable.
  • the invention has for its object to provide a device which is relatively light and not too bulky, but which provides adequate protection against pressure waves, heat, fire and splinters, which can accompany an explosion.
  • the invention achieves this object in that the device has outer walls pointing in opposite directions, one of which points to the explosion source and the other of which points away from the fact that a first of these barriers next to the one outer wall and a second of these barriers next to the is arranged other outer wall and that this first of the barriers is freely movable in a space delimited by the frame and in relation to the frame. Further details are given in subclaims 2 to 12. - It goes without saying that the device according to the invention can form the walls of a container or a protective cell.
  • the components of the device can be made of medium-strength aluminum or steel, depending on how it is required for the specific application.
  • Fig. 1 shows one end of a wall-shaped device according to the invention in cross section in order to be able to represent the position of each component of the device.
  • the individual components are generally made of medium-strength steel or aluminum.
  • the shape, the arrangement and the type of materials used can ent - speaking vary the desired scope.
  • Fig. 1 the position of an explosion point relative to the device is represented by reference numeral A.
  • the components of the device 1 are held together by a frame 2 made of U-profiles. Outside walls 3a, 3b, which can consist of perforated sheet metal, are firmly seated in this frame 2.
  • the term "fixed” is used to describe the seating of the outer surfaces 3a, 3b in the supporting frame 2, which does not mean, however, that these outer surfaces 3 are welded or otherwise attached to the frame 2.
  • the inner components of the device 1 are designed and arranged such that external forces act on the inner regions of the outer walls 3 in order to hold them in the support frame 2. Welding or screwing is neither necessary nor desirable.
  • At least two barriers 4, 5 are arranged within the frame 2, at least one of which is a blind 4, like the blind-like parts 4 in FIG. 1.
  • These blinds 4 are arranged in rows in such a way that a projectile or a splinter is not penetrated by them Protective wall can pass without touching at least a certain part of one of the blind elements 4 '.
  • the Venetian blind elements 4 'V-shaped cross section and are offset from each other in such a way that the aforementioned goal is achieved. As can be seen from FIG.
  • the barrier 4 consists of a first row of blind elements 4 'extending essentially in the same plane and a second row of blind elements extending essentially in a second plane running at a distance from the first plane 4 '.
  • the first row of blind elements 4' is arranged at a selected distance from the second row.
  • the blind elements 4 ' are fixed in relation to a movable auxiliary frame 4' ', which is described in particular with reference to FIG. 2.
  • the second barrier 5 of this preferred exemplary embodiment has two relatively rigid, medium-strength metal sheets 5 'and 6.
  • These sheets 5 1 and 6 are designed as corrugated sheets, the corrugations of the sheets 5' being perpendicular to the corrugations of the sheets 6. Mainly these corrugations make the protection device an excellent shock absorber.
  • the corrugated sheets 5 'and 6 also deliver the outward forces which firmly support the outer walls 3a in the supporting frame 2.
  • Relatively rigid corrugated sheets 5 'and 6 provide a large bending surface over which the force of an explosion can spread, so that the explosion forces are well distributed.
  • each of the outer surfaces 3a, 3b has a number of openings or openings. These openings are arranged in such a way that they do not align with one another in the sheets 3a, 3b, 5 'and 6. In this way, the pressure waves and gases generated during an explosion can flow through the outer walls 3a of the barrier. However, since the breakthroughs of the various sheets are not in alignment with one another, the moving pressure wave is forced to change its direction so that part of the explosive force is reflected.
  • the device according to the invention has screens 7. These screens 7 are arranged on the inside of each outer wall 3a, 3b in a preferred exemplary embodiment according to FIG. 1 and are held there. Sieves 7 are also located on the inside of the two barriers 4, 5.
  • the sieves 7 generally consist of close-meshed aluminum or steel wire mesh. These screens 7 support the distribution of the fire, which can accompany an explosion.
  • the individual components of the device 1 according to the invention shown in FIG. 1 result in an effective but light barrier which can be used to contain the effects of explosions in a portable or mobile container or in a fixed building.
  • the barrier walls can be used as fixed walls in such a portable or mobile container or they can be used as plates are trained, which can then be used in a modular design.
  • each of the barriers 4, 5 is held in place within the device 1 but is movable relative to the frame 2, the forces accompanying an explosion are controlled more effectively than at the previously known protective layers or devices is possible.
  • Fig. 2 clearly shows the mechanism by which the blind elements 4 'are movable within the device.
  • the blind elements 4 1 are welded or otherwise fastened to two plates 4 ′′ arranged at a distance from one another. This creates an auxiliary frame within the device 1, which consists of two plates 4 ′′ with which one end of each blind element 4 ′ is firmly connected. It is important that the plates 4 "are fixed by sieves 7 and the force generated by the corrugated sheets 5 'and 6, which presses the subframe with the blind-like arrangement 4 against the outer surface 3.
  • Fig. 3 shows a portable and mobile container, which is equipped with the device according to the invention.
  • the devices 1 designed according to the invention are arranged along the circumference of the container.
  • a side view of such a container is shown in Fig. 4.
  • Such a container also has wheels 9 and is provided with doors 10 at the end. These front doors 10, when explosive material is stored in the container, kept closed by a system of automatic locking devices 11 such as pneumatic cylinders.
  • the locking system can also be designed remotely.
  • the device 1 according to the invention can be designed in modules to be used in containers as shown in FIGS. 3 and 4, or it can also be produced in larger or smaller dimensions and used in various components to get protection when needed.
