Description

Die Erfindung betrifft ein Verfahren zum Schutz von Gebäuden oder Anlagen gegen äußere Einwirkungen wie es im Oberbegriff des Anspruchs 1 definiert wird. Ein solches Verfahren ist z.B aus der FR-A-911067 bekannt.The invention relates to a method for the protection of buildings or facilities against external influences as defined in the preamble of claim 1. Such a method is for example from the FR-A-911067 known.

Bereits in der DE 43 21 229 A1 wird darauf hingewiesen, dass industrielle Anlagen gegen Einwirkungen von außen oder von innen geschützt werden müssen. Unter anderem werden äußere Einwirkungen als Folge von Naturkatastrophen wie Erdbeben, Überschwemmungen oder Brände, Zug- und Flugzeugunglücke oder sonstige Explosionen genannt. Um eine industrielle Anlage mit sicherheitstechnisch relevanten Komponenten zu schützen, wird in der DE 43 21 229 A1 vorgeschlagen, alle sicherheitstechnisch relevanten Komponenten innerhalb einer äußeren Hülle anzuordnen, die aus einem Fundament sowie einem hierauf aufgesetzten Kreiszylinder oder Kegelstumpf und einem auf diesem Kreiszylinder bzw. Kegelstumpf aufgesetzten, diesen abdeckenden Schalenelement besteht. Die äußere Hülle soll überwiegend aus Stahlbeton bestehen. Eine solche Schutzeinrichtung ist für chemische Anlagen mit hochgiftigen oder hochexplosiven Stoffen oder den Primärkreislauf eines Kernkraftwerkes konzipiert, wobei die zu schützenden Anlagenteile in einer allseits geschlossenen Stahlbetonhülle anzuordnen sind. Die Stahlbetonhülle ist ggf. so auszulegen, dass sie einen hinreichenden Widerstand gegen ein abstürzendes Flugzeug bildet.Already in the DE 43 21 229 A1 It is pointed out that industrial installations must be protected against external or internal influences. Among other things, external impacts due to natural disasters such as earthquakes, floods or fires, train and aircraft accidents or other explosions are mentioned. In order to protect an industrial plant with safety - relevant components, the DE 43 21 229 A1 proposed to arrange all safety-relevant components within an outer shell, which consists of a foundation and an attached thereto circular cylinder or truncated cone and a patch on this circular cylinder or truncated cone, this covering shell element. The outer shell should consist predominantly of reinforced concrete. Such a protective device is designed for chemical plants with highly toxic or highly explosive substances or the primary circuit of a nuclear power plant, the parts of the system to be protected are to be arranged in a reinforced concrete cover which is closed on all sides. The reinforced concrete shell may need to be designed so that it provides adequate resistance to a falling aircraft.

Wie die Terroranschläge vom 11. September 2001 auf das World Trade Center sowie auf ein US-Regierungsgebäude zeigen, besteht ein großes Bedürfnis, solche Zielobjekte und die darin arbeitenden Menschen zu schützen. Abgesehen davon, dass der Aufwand zur Einhausung von zu schützenden Gebäuden oder Anlagen relativ groß ist, haben geschlossene Schutzhüllen auch den Nachteil, das in deren Innerem nur unter künstlichem Licht gearbeitet werden kann, was aus arbeitsphysiologischen Gründen vermieden werden sollte.As the September 11, 2001 terrorist attacks on the World Trade Center and a US government building show, there is a great need to protect such targets and the people working in them. Apart from the fact that the cost of housing to be protected buildings or facilities is relatively large, closed protective covers also have the disadvantage that can be worked in the interior only under artificial light, which should be avoided for work physiological reasons.

Die FR-A-729959 und die FR-A-911067 beschreiben ein Verfahren und eine Vorrichtung zum Schutz gegen einen Bombenangriff aus der Luft, wozu zwischen Pylonen ein engmaschiges Stahlnetz aufgespannt ist.The FR-A-729959 and the FR-A-911067 describe a method and a device for protection against an aerial bombardment, for which a tight-mesh steel net is spanned between pylons.

Die US 2,100,111 befasst sich ebenfalls mit einer Bombenschutzvorrichtung für Gebäude, Brücken oder ähnliches, die aus mehreren in Rahmen gefassten übereinander liegenden Stahlnetzen besteht, die über Seile gespannt sind, die endseitig über Federn fixiert sind.The US 2,100,111 is also concerned with a bomb protection device for buildings, bridges or the like, which consists of a plurality of superimposed in-frame steel nets, which are stretched over cables, which are fixed at the ends by springs.

Die US 2,348,387 behandelt eine Bombenschutzvorrichtung, die einen an Pfosten befestigten Rahmen mit eingehängten flexiblen Netzen besitzt.The US 2,348,387 deals with a bomb protection device having a post-mounted frame with hinged flexible nets.

Alle vorbeschriebenen Vorrichtungen sind so ausgelegt, dass abgeworfene Bomben von den Netzen aufgefangen und damit von den zu schützenden Objekten ferngehalten werden.All devices described above are designed so that dropped bombs are collected by the networks and thus kept away from the objects to be protected.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren zum Schutz von Gebäuden oder Anlagen gegen äußere Einwirkungen zu schaffen, bei dem die gewählte Gebäudeform möglichst nach außen optisch erhalten bleibt und zu dem die Schutzvorrichtung ohne größeren technischen Aufwand nachrüstbar ist und den natürlichen Lichteinfall - zumindest weitestgehend - nicht behindert.It is therefore an object of the present invention to provide a method for the protection of buildings or facilities against external influences, in which the selected building form optically preserved as possible to the outside and to which the protective device can be retrofitted without major technical effort and the natural light - at least as far as possible - not handicapped.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, dass um wenigstens einen Teil des Gebäudes oder der Anlage Drahtseile gemäss Anspruch 1 gespannt sind. Drahtseile wirken bei zielgerichtet gesteuerten Flugzeugen wie auch bei Flugzeugunglücken auf Flugzeugteile wie Schneidwerkzeuge. Die Drahtseile fangen bereits einen großen Teil der kinetischen Energie des dort auftreffenden Flugzeugkörpers ab, der hierbei bereits partiell beschädigt oder zerstört wird. Der Aufprall des Flugzeuges auf Drahtseile führt zudem dazu, dass entsprechend dem Abstand der Drahtseile zum Gebäude unvermeidliche Explosionen früher stattfinden, so dass deren Wucht nur eingeschränkt das Gebäude erreicht. Die gespannten Seile können zwar nicht verhindern, dass Flugzeugteile auf das Gebäude fallen, jedoch ist der hierdurch angerichtete Schaden deutlich geringer im Vergleich zu dem Schaden, der beim Eindringen eines Flugzeuges in das Gebäude oder eine Anlage eintritt, innerhalb der sich dann die unvermeidlichen Explosionen verheerend auswirken. Die Anordnung der Seile, insbesondere deren gegenseitiger Abstand, der Abstand vom Gebäude und deren Stärke kann den jeweilig gewünschten Schutzbedingungen angepaßt bzw. auf die mit erträglichem Aufwand möglichen Nachrüstungen an einem Gebäude angepaßt werden.To solve this problem, the invention proposes that are stretched around at least part of the building or the plant wire ropes according to claim 1. Wire ropes act on purposefully controlled aircraft as well as aircraft accidents on aircraft parts such as cutting tools. The wire ropes already absorb a large part of the kinetic energy of the plane body impinging there, which is already partially damaged or destroyed. The impact of the aircraft on wire ropes also means that according to the distance of the wire ropes to the building unavoidable explosions take place earlier, so that their impact reaches the building only limited. Although the tensioned ropes can not prevent aircraft parts from falling onto the building, the damage caused thereby is significantly less compared to the damage that occurs when an aircraft enters the building or an installation, within which the inevitable explosions devastate impact. The arrangement of the ropes, in particular their mutual distance, the distance from the building and its strength can be adapted to the respective desired protection conditions or adapted to the possible retrofitting at a building with bearable effort.

Weitere Ausbildungen der Erfindung sind in den Unteransprüchen beschrieben. So sind mindestens einige der Drahtseile oberhalb des Gebäudes oder der Anlage angeordnet, vorzugsweise in einem Abstand von mindestens 10 m. Der wirksamste Schutz für ein Gebäude ist dann gegeben, wenn der Abstand der jeweiligen Drahtseile von dem Gebäude möglichst groß ist. Dies hängt jedoch im wesentlichen von der Höhe des zu schützenden Gebäudes sowie dem für die "Abspannung" der Drahtseile notwendigen Platz ab.Further embodiments of the invention are described in the subclaims. Thus, at least some of the cables are arranged above the building or the plant, preferably at a distance of at least 10 m. The most effective protection for a building is given when the distance of the respective wire ropes from the building is as large as possible. However, this depends essentially on the height of the building to be protected and the space necessary for the "bracing" of the wire ropes.

Abspannungen sind prinzipiell bei Sendemasten bekannt, wobei der Winkel, unter dem das Seil bzw. die Seile vom Mast zum Boden geführt werden, wo sie jeweils verankert werden, 45° oder weniger beträgt. Im einfachsten Fall sind die Drahtseile so mit Abspannungen von einzelnen Masten, die auf dem zu schützenden Gebäude oder der Anlage oder seitlich hiervon aufgestellt sind. Die Drahtseile können alternativ oder zusätzlich zwischen Stützpfeilern gespannt sein. Bei Gebäuden mit mehreren Türmen ist es auch möglich, zwischen den Türmen Seile zu spannen. Bei hohen Türmen ist es auchmöglich, von dem Turm horizontal abstehende Träger vorzusehen, zwischen denen Drahtseile gespannt sind. Bei höherem Gebäudeschutz ist es auch möglich, aus der Gesamtheit der Drahtseile und der Stützpfeiler eine selbsttragende Schutzhülle zu bilden, die ein allseitiges grobes Netzwerk bildet. Der Abstand paralleler Drahtseile voneinander beträgt entsprechend der Flügelspannweite von Flugzeugen zwischen 5 bis 15 m, vorzugsweise etwa 10 m. Wesentlich ist, dass die größte "Maschenweite" eines solchen Netzwerkes kleiner als die Flügelspannweite eines Flugzeuges ist, vor dessen ungehindertem Aufprall das Gebäude geschützt werden soll. Einem bereist respektablen Schutz liefern Stahl-Drahtseile mit einer Durchmesserdicke von mindestens 0,5 cm. Dünnere Seile haben zwar den Nachteil einer geringeren Reißfestigkeit, jedoch "schneidet" ein solche Seil wesentlich wirksamer. Demgegenüber haben dickere Seile den Vorteil einer höheren Reißfestigkeit. Hinsichtlich der Seilmaterialwahl und dem Seilaufbau kann auf die Kenntnisse zurückgegriffen werden, die bei Abspannseilen für Sendemasten grundsätzlich bekannt ist.Suspensions are known in principle in transmission towers, wherein the angle at which the cable or ropes are guided from the mast to the ground, where they are anchored, is 45 ° or less. In the simplest case, the wire ropes are so with braces of individual masts, which are placed on the protected building or plant or laterally thereof. The wire ropes can alternatively or additionally be stretched between buttresses. In buildings with several towers, it is also possible to stretch cables between the towers. For tall towers, it is also possible to provide horizontally projecting supports from the tower, between which wire ropes are stretched. With higher building protection, it is also possible to form of the totality of the wire ropes and the pillars a self-supporting protective cover, which forms an all-round coarse network. The distance between parallel wire ropes is between 5 and 15 m, preferably about 10 m, according to the wing span of aircraft. It is essential that the largest "mesh size" of such a network is smaller than the wing span of an aircraft against whose unimpeded impact the building is to be protected. A respectable protection provide steel wire ropes with a diameter of at least 0.5 cm. Although thinner ropes have the disadvantage of lower tensile strength, but "cuts" such a rope much more effective. In contrast, thicker ropes have the advantage of a higher tensile strength. With regard to the choice of rope material and the rope construction can be made of the knowledge that is basically known in guy ropes for transmission towers.

Um die Schneidwirkung der Drahtseile zu erhöhen, ist es nach einer Weiterentwicklung der Erfindung ferner möglich, die Drahtseile an ihrer Oberfläche mit einem Wellenschliff zu versehen, wie er beispielsweise bei Brot- oder Allzweckmessern bekannt ist. Der Wellenschliff ist optimal, weil die Drahtseile im Querschnitt nicht rund, sondern messerklingenförmig ausgebildet sind. In diesem Fall wird die Schneidwirkung erheblich erhöht.In order to increase the cutting action of the wire ropes, it is also possible according to a further development of the invention to provide the wire ropes on its surface with a serrated edge, as is known for example in bread or utility knives. The serrated edge is optimal because the wire ropes are not round in cross-section, but knife blade shaped. In this case, the cutting effect is significantly increased.

Im Rahmen der vorliegenden Erfindung ist es auch möglich, im Bereich der Seilabspannung federnde Körper vorzusehen, insbesondere Schraubenfedern. Diese Federn erhöhen die Elastizität des Seiles, das bei einem Flugzeugaufprall bis zum Erreichen der maximalen Spannung vor dem Zerreißen des Seiles oder der Feder längere Zeit verbleibt, um eine Schneidwirkung auszuüben.In the context of the present invention, it is also possible to provide resilient bodies in the region of the cable guy, in particular coil springs. These springs increase the elasticity of the rope which, in the event of an aircraft impact, remains for a long time until the maximum tension is reached before the rope or spring tears, in order to exert a cutting action.

Weitere Vorteile und Ausführungsbeispiele für die erfindungsgemäße Schutzvorrichtung werden im folgenden anhand der Zeichnungen erläutert.Further advantages and embodiments of the protective device according to the invention are explained below with reference to the drawings.

Schematic representations of each protected by wire ropes buildings 10, which are shown here as a cube or cuboid.

Entsprechend Fig. 1 ist auf dem Gebäudedach ein Mast 11 angeordnet, der eine möglichst große Höhe besitzen soll. Von diesem Mast 11 ausgehend sind mehrere Seile 12 gespannt und in betonierten Flächen 13 bodenseitig verankert. Je nach Gebäudegröße und Masthöhe können auch mehr als vier Seile 12 verwendet werden.Corresponding Fig. 1 is arranged on the building roof a mast 11, which should have the greatest possible height. Starting from this mast 11, several cables 12 are stretched and anchored on the bottom side in concrete surfaces 13. Depending on the size of the building and the height of the mast, more than four ropes 12 can be used.

In der alternativen Ausführungsform nach Fig. 2 sind vier seitlich des Gebäudes dargestellte Stützen 14 vorgesehen, die mit Seilen 12 abgespannt sind und zwischen denen zusätzliche Seile 15 gespannt sind, an denen quer wie längs weitere Seile 16 und 17 - hier kreuzweise - verlaufen. Ggf. können noch zusätzliche Abspannseile 18, die im Boden verankert sind, vorgesehen sein. Selbstverständlich können auch mehr als vier Stützen verwendet werden. Die Drahtseile 15 und 16 können nach einer Ausgestaltung der Erfindung locker eingehängt sein, so dass im Falle eines Flugzeugaufpralls die Gefahr vermieden wird, dass wegen der bestehenden Spannung die Seile schneller reißen.In the alternative embodiment according to Fig. 2 are four side of the building shown supports 14, which are guyed with ropes 12 and between which additional cables 15 are stretched at which transversely as longitudinally more ropes 16 and 17 - here crosswise - run. Possibly. can still additional guy ropes 18 which are anchored in the ground, may be provided. Of course, more than four supports can be used. The cables 15 and 16 may be hung loosely according to an embodiment of the invention, so that in the event of an aircraft crash, the risk is avoided that break because of the existing tension the ropes faster.

Nach Fig. 3 sind zwei (oder mehr), als Boden ausgebildete Stahlprofile 19 und 20 vorgesehen, zwischen deren Abstand mehrere Seile 21 gespannt sind oder entsprechend den Seilen 15 und 16 lose einhängen. Diese selbsttragende Konstruktion "überbrückt" das Gebäude 10, wobei zwischen den Seilen 21 und dem Dach des Gebäudes 10 ein möglichst großer Abstand bestehend soll. Ggf. können auch hier über einen auf dem Gebäudedach befestigten Mast zusätzliche Seilabspannungen entsprechend Fig. 1 vorgesehen sein, so dass der Schutz weiterhin vergrößert wird.To Fig. 3 are two (or more) designed as a bottom steel sections 19 and 20 are provided between the distance a plurality of cables 21 are tensioned or accordingly Hang the ropes 15 and 16 loose. This self-supporting construction "bridges" the building 10, wherein between the ropes 21 and the roof of the building 10 as large a distance as possible should exist. Possibly. Here, too, additional rope suspensions can be correspondingly provided via a mast fastened to the building roof Fig. 1 be provided so that the protection is further increased.

Die Seile 12, 15, 16, 17 und/oder 21 können auch an ihren Enden oder durch entsprechende Zwischenstücke mit Stahl-Schraubenfedern verbunden sein, durch die die Elastizität der Seil-Konstruktionen erhöht wird. Ein unmittelbar bei einem Flugzeugaufprall auf straff gespannte Seile drohendes Zerschneiden bzw. Zerreißen dieser Seile wird damit verhindert, zumindest erheblich verzögert. Mit der Vergrößerung der Elastizität erhöht sich auch die "Sägewirkung", welche diese Seile auf Teile des herabstürzenden Flugzeuges ausüben.The ropes 12, 15, 16, 17 and / or 21 may also be connected at their ends or by means of corresponding intermediate pieces with steel coil springs, by which the elasticity of the rope constructions is increased. A directly threatening in an aircraft collision on tightly stretched ropes cutting or ripping of these cables is thus prevented, at least significantly delayed. As the elasticity increases, so does the "sawing effect" which these ropes exert on parts of the falling aircraft.

Je größer der Abstand der Seile zu dem zu schützenden Gebäude oder einer chemischen Anlage ist und je stabiler gegen ein Reißen die Seile 12 , 15, 16, 17 und/oder 21 sind, desto wahrscheinlicher ist die Abbremsung des herabstürzenden oder zielgerichtet gesteuerten Flugzeuges sowie dessen Zerstörung. Zwar kann nicht verhindert werden, dass Flugzeugteile auf das Gebäude 10 abstürzen, jedoch ist deren Wucht erheblich gebremst. Darüber hinaus werden etwaige drohende Explosionen außerhalb des zu schützenden Gebäudes 10 verlagert.The greater the distance of the ropes from the building or chemical installation to be protected, and the more stable the ropes 12, 15, 16, 17 and / or 21 are against tearing, the more likely is the deceleration of the falling or purpose controlled aircraft and the latter Destruction. Although it can not be prevented that aircraft parts crash on the building 10, but their power is significantly slowed down. In addition, any impending explosions outside the building 10 to be protected are relocated.

Insbesondere kommt durch die gewählte Konstruktion ein Schutz für Kernkraftwerke in Betracht, der auch mit der Hülle gemäß DE 43 21 229 A1 kombiniert werden kann. Soweit bei einem bereits vorhandenen Stahlmantel zusätzlich die Drahtseilabspannung vorgesehen ist, besteht ein deutlich verbesserter Gebäudeschutz, der es unwahrscheinlich macht, dass die zu schützenden Anlagenteile beschädigt werden.In particular, by the chosen construction, a protection for nuclear power plants into consideration, which also with the shell according to DE 43 21 229 A1 can be combined. Insofar as cable ropes are additionally provided in the case of an existing steel casing, there is a markedly improved protection of the building, which makes it unlikely that the system components to be protected will be damaged.
