Definitions

  • the invention relates to a system for protecting buildings from terrorist attacks, in particular explosives, with a protective wall in front of the building.
  • the outer walls of the endangered structures are at a relatively large distance from z. B. provided about 100 m relatively high barbed wire fences or erected concrete walls.
  • these obstacles can be overcome relatively quickly by terrorists with special tools or by blasting, so that the time to alert the police and their appearance at the crime scene is too short to destroy the exterior of the building, the terrorists' intrusion into the building, to prevent their actual work of destruction inside the building and their escape.
  • Sufficient security to prevent logistically mostly carefully prepared acts of terrorism is therefore usually not given at all.
  • the purpose of the invention is to remedy the above-mentioned disadvantages of the known protective systems, and it is therefore based on the object of creating a protective system of the type mentioned at the outset, in which the protective wall in front of the outer wall of the structure is not or only with great difficulty and therefore A relatively large amount of time can be overcome by terrorists, whereby the time required to partially destroy them should be as long as possible, so that the time required to alert the police, to show them in time at the scene and thus to thwart the actual terrorist attack directed against the building itself, how, if possible, to ensure the arrest of terrorists with greater certainty than before.
  • the invention relates to a protective system of the type mentioned at the outset, which according to the invention is characterized in that the protective wall is provided with a combustible mass to delay the terrorist attack due to the development of flames and smoke, and that ignition devices are embedded in this in that these an explosive explosion can be triggered by deformation of the protective wall and contain two coordinated amounts of two spaced-apart compounds or raw materials that only react chemically with one another exothermically when they come into contact with each other to trigger and thus set the flammable mass into fire.
  • the progress achieved with the invention compared to the previously known protective systems consists in the fact that in the case of acts of terrorism it is usually practically impossible to overcome the protective wall and, even when using highly developed professional methods of perpetrator, is so delayed by the intense heat and smoke development of the combustible mass ignited by the ignition device that Even if the protective wall could finally be overcome by the terrorists, the actual terrorist attack on the object to be destroyed can be thwarted with sufficient certainty thanks to the timely alerting of the police to the relatively large amount of time required for the local destruction of the protective wall.
  • the protective system according to the invention can also be used where the local space conditions do not allow such a large protective distance; this is particularly the case if the protective wall consists of two or even several wall walls arranged one behind the other, formed from armored elements and each self-contained.
  • Fig. 1 is a vertical outer wall of the structure to be protected, e.g. a power plant, designated 1.
  • the wall 1 is placed at a relatively short distance from a generally designated 2, also vertically extending protective wall.
  • the protective wall 2 consists essentially of supporting pillars 3, two support nets 4 attached to them and armor elements 5 suspended therein.
  • the supporting pillars 3 are arranged in a row running parallel to the outer wall 1 of the building and at their upper ends with one another same, projecting forward cantilever arms 6, on each of which live in two mutually parallel verticals a support net 4 is attached.
  • two vertical, mutually parallel walls are formed from the two support nets 4 and the armor elements 5 suspended therein, the armor elements 5 placed against one another with horizontal and vertical butt joints representing two self-contained hanging walls H1 and H2 (cf. also Fig. 3 with the front hanging wall H1).
  • the cavity between these two hanging walls is filled with barbed wire rolls 7.
  • the protective wall 2, which here is, for example, about 1 m thick and with its rear wall surface 9 is about 1 m distant from the facade 10 of the building's outer wall 1, is protected against atmospheric precipitation by a narrow, inclined roof 8.
  • each armor element 5 consists of a cuboidal steel sheet box 11 which is closed on all sides, a armor plate 12 which is inserted in the front of its cavity and a combustible mass 13 which fills the remaining box cavity on the back, and for its ignition from a plurality of ignition devices 14 which are inserted into the combustible Mass 13 are embedded.
  • the sheet steel box 11 is closed by a rectangular sheet steel plate 15 welded onto its rear side.
  • the armor element 5 is provided with hook-like brackets 16 welded on the rear to the sheet steel plate 15 and hung with them into the support net 4.
  • the thickness of an armored element 5 here is, for example, approximately 80 mm in the exemplary embodiment according to FIG. 2.
  • the armor elements 5 are arranged one above the other in horizontal rows, wherein they are joined together with vertical butt joints 17.
  • the armored elements 5 are identical to one another here, and their butt joints 17 are offset from one another from row to row.
  • the length of a tank element 5 is, for example, approximately 2 m, its height e.g. approx. 1 m.
  • FIG. 3 also shows that and how a self-contained front hanging wall H1 is formed by the front support net 4 and the armor elements 5 suspended therein (cf. also FIG. 1 with FIG. 3).
  • FIG. 4 illustrates that or how a single ignition device, generally designated 14, is embedded in the combustible mass 13.
  • the ignition device 14 here consists, for example, of a glass ampoule 18, an amount of a chemical compound 19 of a liquid “mold type” (or “physical state”) and an amount of another chemical compound 20 of e.g. powdery, i.e. thus fixed «form type».
  • the two chemical compounds 19 and 20 are substances between which there is great specific connectivity, i.e. There is a high so-called «chemical affinity», so that when they are brought together, a rapid, exothermic chemical reaction takes place and thus immediately releases a relatively large amount of heat and therefore a relatively high temperature, it is the ignition temperature for the combustible mass 13, is generated, although the course of the chemical reaction depends not only on the substances involved, but also (apart from the temperature and pressure) on their quantitative ratio.
  • the protective wall 2 (cf. FIG. 1) with explosives
  • at least one of the ampoules 18 lying in the area of the explosive device bursts due to the deformation of the armor plate 12 affected thereby; this is all the more certain since the length of each ampoule is a multiple of its diameter, i.e. the ampoule is relatively “slim”.
  • the ampoule 18 bursts its contents pour out, i.e. the filled amount of the liquid compound 19, into the amount of the solid compound 20 immediately surrounding the ampoule, which in a matter of seconds triggers the chemical reaction required to ignite the combustible mass 13 between the two substances 19/20.
  • the combustible mass 13 set on fire immediately develops - it can consist, for example, of largely shredded old car tires (shredded tires) - in a large amount of flue gases, but at the same time also a great deal of heat, which, of course, at least greatly hinders the continued work of the terrorists and thereby significantly delayed.
  • the armor plates 12 If an explosive charge is used in the terrorist attack, at least one of the armor plates 12 is torn or at least bent, i.e. very deformed. As a result, however, at least one of the ampoules 18 located in the armor element 5 is broken as a result of the detonation, and the liquid 19 then emerges from it and reaches the powdery, i.e. firm connection 20. If, however, an oxygen lance or a welding torch is used in the terrorist attack, the combustible mass 13 is set on fire anyway due to the enormous local heat development which occurs, in which case the function and effect of the ignition device 14 may function as an “ignition booster”. would come. The ignition device 14 is therefore of very great importance for a terrorist attack by means of an explosive charge, especially since explosives in particular are probably the most widely used aid for serious acts of terrorism today.
  • the ignition device 14 is embedded in the combustible mass 13, for example, as follows:
  • a recess 21 was formed in the combustible mass 13, which was initially only partially filled into the steel sheet box 11 (see FIG. 2), and the amount of the solid connection 20 was then pressed into it (see FIG. 4). Thereupon, the ampoule 18 filled with the amount of the liquid compound 19 was in turn pressed into the amount of the solid connection 20, so that it is encircled approximately semi-cylindrical by the latter on the front side exposed to the terrorist attack. Finally, the ampoule 18 was on the back, i.e. on the side facing the power plant facade, covered with the remaining combustible mass 13 to be used (cf. FIG. 4).
  • the armored plate 12 of an armored element 5 of the lowest row of elements would be perforated on the front hanging wall H1 in the worst case.
  • one of the ignition devices 14 would be triggered, which would immediately set the combustible mass 13 on fire, which would cause a strong development of flames and flue gases.
  • the relatively narrow hole in the armor plate 5 has to be expanded many times by the terrorists, but they are at least severely hampered by the flames and the escaping hot smoke gases, which hinders their further work, i.e. the attack on the second rear wall H2, delayed accordingly, if not impossible.
  • the time saved until the police arrive on time can be further optimized by the increasing disability of the terrorists as a result of the spatial conditions that are disadvantageously changing for them.
  • the terrorists should succeed in overcoming the first hanging wall H1, they have to get closer to it so that they can also tackle the second hanging wall H2 with the oxygen lance or the welding torch, and they must, if they can also overcome it should then continue to advance under increasingly difficult spatial and physical conditions, to get to the outer wall of the building in the first place.
  • the protective wall 2 is expediently provided on its two narrow end faces with end walls which extend as far as the facade 10 of the outer wall 1 of the building and extend up to the roof 8 (cf. FIG. 1).
  • the police alarm system is already known and is therefore not shown in the drawings for greater clarity.
  • the question here is e.g. a vibration button serving as a mechanical pulse receiver, which triggers the alarm in the police station via a pulse converter, which converts the mechanical pulses into electrical ones.
  • Other donors e.g. Thermal sensors and / or special microphones should also be considered here.

Abstract

Pour protéger une construction contre des actes de terrorisme, notamment des attentats à l'explosif, on place devant elle une paroi de protection exigeant beaucoup de temps pour sa destruction. Cette paroi de protection se compose d'une rangée de piliers auxquels est suspendu un filet de support (4) et d'éléments de blindage (5) en forme de caisson constituant une paroi suspendue (H1) fermée, accrochée par des crochets (16) au filet. Chaque élément de blindage (5) comprend une plaque frontale (12) et un remplissage constitué par une matière inflammable (13) dans laquelle sont noyés des dispositifs d'allumage (14) qui se déclenchent sous l'influence d'explosions d'explosifs ou d'autres méthodes d'agression et mettent le feu à la matière inflammable (13). Les flammes naissantes et les gaz empêchent la progression des terroristes.
