Abstract

A walk-in shelter providing protection against undesired heat, radiation, gas and water action, as well as mechanical stressing, particularly for data carriers is proposed, in which the walls comprise several different layers. The inner and outer layers are constructed as a closed metal envelope. Between the outer and inner layers is provided a metal supporting frame and between the outer layer, supporting frame and inner layer are provided insulating layers with high thermal insulation and mechanical strength. All the layers are set up independently of one another, are self-supporting and not mechanically interconnected.

Description

Die Erfindung betrifft ein begehbares Schutzhaus gegen unerwünschte Wärme-, Strahlungs-, Gas- und Wassereinwirkung und sonstige mechanische Beanspruchungen, insbesondere für Datenträger.The invention relates to a walk-in shelter against unwanted exposure to heat, radiation, gas and water and other mechanical stresses, in particular for data carriers.

Es besteht seit langem das Bedürfnis, wichtige Dokumente, Datenträger, Chemikalien oder dergleichen so zu lagern, daß sie bei unerwünschter Einwirkung von außen, beispielsweise die erhöhte Wärmeeinwirkung bei einem Brand oder eine Strahleneinwirkung oder dergleichen, nicht zerstört werden. Das zu lagernde Gut wird üblicherweise in abgeschlossenen Tresoren oder Schränken aufbewahrt, in denen es sicher gegen fremden Zugriff ist, Vorkehrungen für den Brandfall sind aber meistens nicht getroffen.There has long been a need to store important documents, data carriers, chemicals or the like in such a way that they are not destroyed in the event of undesired external influences, for example the increased heat exposure in the event of a fire or radiation or the like. The goods to be stored are usually kept in locked safes or cupboards, in which they are secure against unauthorized access, but no measures are usually taken in the event of a fire.

Der Erfindung liegt daher die Aufgabe zugrunde, ein begehbares Schutzhaus zur Aufbewahrung von Dokumenten, insbesondere Datenträger oder von Chemikalien oder dergleichen zu schaffen, in dem die Gegenstände gegen unerwünschte Wärmeeinwirkung, beispielsweise während eines Brandes, Strahlungs-, Gas- oder Wassereinwirkung oder gegen sonstige mechanische Beanspruchungen sicher und zerstörungsfrei geschützt sind, wobei das Schutzhaus einen einfachen Aufbau haben soll, der in seiner Größe leicht an die geforderten Gegebenheiten angepaßt werden kann.The invention is therefore based on the object to provide a walk-in shelter for storing documents, in particular data carriers or chemicals or the like, in which the objects against undesired heat, for example during a fire, radiation, gas or water or against other mechanical Stresses are protected safely and non-destructively, the shelter should have a simple structure, the size of which can easily be adapted to the required conditions.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmalen des Hauptanspruchs in Verbindung mit den Merkmalen des Oberbegriffs gelöst.This object is achieved by the characterizing features of the main claim in connection with the features of the preamble.

Dadurch, daß die Wandungen von außen nach innen gesehen aus einer geschlossenen äußeren Metallhülle, einer oder mehreren Isolierschichten. einem Stützwerk, einer weiteren oder mehreren weiteren Isolierschichten und einer inneren geschlossenen Metallhülle aufgebaut sind, ist ein sicherer Schutz insbesondere gegen Brand- oder Strahleneinwirkung gegeben, wobei der Schutz noch dadurch erhöht wird, daß die einzelnen Schichten unabhängig voneinander errichtet und selbsttragend und mechanisch nicht miteinander verbunden sind. Jedes Teil erfüllt dabei seine ihm zugeordnete Funktion ohne die Hilfe der anderen. Die innere und äußere Metallhülle bilden einen doppelten Faraday'schen Käfig, so daß ein böswilliges oder unbeabsichtigtes Entmagnetisieren von als Magnetbänder oder Disketten oder dergleichen ausgebildeten magnetischen Datenträgern nicht möglich ist.Characterized in that the walls seen from the outside inwards from a closed outer metal shell, one or more insulating layers. A support structure, a further or more additional insulating layers and an inner closed metal shell provide reliable protection, in particular against the effects of fire or radiation, the protection being increased further by the fact that the individual layers are built independently of one another and are not self-supporting and mechanically with one another are connected. Each part fulfills its assigned function without the help of the others. The inner and outer metal shells form a double Faraday cage, so that malicious or unintentional demagnetization of magnetic data media designed as magnetic tapes or floppy disks or the like is not possible.

Durch die in den Unteransprüchen angegebenen Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen möglich.Advantageous further developments and improvements are possible through the measures specified in the subclaims.

Der modulare Aufbau gestattet es, Schutzhäuser in beliebigen Größen auszubilden, ohne daß die Struktur oder die einzelnen Elemente geändert werden müssen.The modular structure allows shelters to be designed in any size without having to change the structure or the individual elements.

Dadurch, daß die Wärmespeicherfähigkeit und/ oder die Masse der einzelnen Schichten von außen nach innen zunimmt, ist das Schutzhaus an das Temperaturverhalten eines Brandes angepaßt, bei dem die Temperaturen am Anfang schnell steigen und nach einem gewissen Zeitraum, der im Bereich von einer Stunde liegt, annähernd exponentiell abfallen. Der Wärmedurchgang wird durch den erfindungsgemäßen Aufbau nach innen verzögert, und nach Abklingen der Temperaturen im Außenraum kann der Wärmetransport wieder von innen nach außen erfolgen. Der Innenraum heizt sich daher nicht so stark auf, daß die Dokumente oder Datenträger zerstört werden.Due to the fact that the heat storage capacity and / or the mass of the individual layers increases from the outside inwards, the shelter is adapted to the temperature behavior of a fire in which the temperatures rise quickly at the beginning and after a certain period of time which is in the region of an hour , fall approximately exponentially. The heat transfer is delayed to the inside by the structure according to the invention, and after the temperatures in the outside have subsided, the heat can be transported again from the inside to the outside. The interior therefore does not heat up so much that the documents or data carriers are destroyed.

Durch Versetzen der Stützen des Stützenwerks und der Stoßstellen der Blechelemente sind die heißen Zonen versetzt, so daß die Wärme gleichmäßig verteilt wird und keine Wärmebrücken entstehen.By moving the supports of the support structure and the joints of the sheet metal elements, the hot zones are offset so that the heat is distributed evenly and no thermal bridges are created.

Die Dichtungen zwischen den Blechelementen der inneren Metallhülle bilden zusammen mit den Blechelementen eine Dampfsperre, so daß die Feuchtigkeit, die beispielsweise während eines Brandes freigesetzt wird oder die aufgrund von Partialdruckunterschieden vorhanden ist, nicht in den Innenraum gelangt. Da magnetische Datenträger bei 100 % Feuchte entmagnetisiert werden, ist diese Maßnahme unerläßlich.The seals between the sheet metal elements of the inner metal shell form a vapor barrier together with the sheet metal elements, so that the moisture which is released, for example, during a fire or which is present due to differences in partial pressure does not reach the interior. Since magnetic data media are demagnetized at 100% humidity, this measure is essential.

Der Aufbau der Tür mit dem Mehrfachfalzen gewährleistet einen sicheren Abschluß der notwendigen Öffnung im Schutzhaus. Durch das parallele Herausbewegen und das anschließende Schwenken muß nicht auf das aufwendige Zweitüren-System zurückgegriffen werden.The structure of the door with the multiple rebate ensures that the necessary opening in the shelter is securely closed. Due to the parallel moving out and the subsequent pivoting, there is no need to resort to the complex two-door system.

Die Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert. Es zeigen :

  • Fig. 2 eine vergrößerte Schnittdarstellung durch eine der Wandungen des Schutzhauses, und
  • Fig. 3 eine Darstellung der Tür mit den das Herausbewegen und Schwenken steuernden Hebeln.
The invention is illustrated in the drawing and is explained in more detail in the description below. Show it :
  • 1 shows a section through the shelter parallel to the ceiling or floor,
  • Fig. 2 is an enlarged sectional view through one of the walls of the shelter, and
  • Fig. 3 is an illustration of the door with the levers controlling the movement and pivoting.

Wie aus den Fig. 1 und 2 zu erkennen ist, besteht das Schutzhaus aus mehreren Schichten, wobei der Aufbau für die Wände, die Decken und den Boden gleich ist. Die Außenschicht des Schutzhauses 1 besteht aus einer durchgehenden Metallhülle 2, die durch einzelne miteinander verbundene Blechelemente 3 gebildet wird. Die Blechelemente 3 sind in ihren Randbereichen zweimal senkrecht abgebogen, so daß sich in diesen Randbereichen ein im Querschnitt U-förmiges Profil ergibt. An den senkrecht zur Außenhülle abgeknickten Winkelstücken 4 sind die Blechelemente 3 durch Schrauben, Nieten, Schweißen oder dergleichen miteinander verbunden. In die Blechelemente 3 ist jeweils eine Isolierschicht 5 mit hoher Wärmedämmung und mechanischer Festigkeit, beispielsweise Steinwolle, eingeschoben, die durch das U-Profil der Randbereiche der Blechelemente 3 gehalten wird. An die in den Blechelementen 3 gehaltene Isolierschicht 5 schließt sich eine weitere Isolierschicht 6 aus dem gleichen oder ähnlichen Material wie die Isolierschicht 5 an, wobei die mechanische Festigkeit des Wärmedämmaterials ausreichend sein muß, damit die Isolierschicht 6, die an den parallel zur äußeren Fläche der Blechelemente 3 liegenden abgeknickten Randbereichen 7 der Blechelemente 3 anliegt, sich selbst trägt. An die Isolierschicht 6 schließt sich ein Stützenwerk aus Profilträgern 8 an, wobei die Träger 8 ein U-Profil aufweisen und durch Schweißen, Nieten oder Schrauben derart miteinander verbunden sind, daß sich ein H-Profil ergibt. Selbstverständlich können auch Träger mit anderen Profilen verwendet werden. Ebenso wie die anderen Schichten 2, 5, 6 ist das Stützenwerk selbsttragend und mechanisch nicht mit der Isolierschicht 6 oder den Blechelementen 3 verbunden. In die U-Profile der Träger 8 sind Wärmedämmplatten 9 eingelegt. In Richtung Innenraum ist eine weitere Isolierschicht 10, eine Schicht aus Gipskarton-Platten 11 und wiederum eine Isolierschicht 12 vorgesehen. Entsprechend der äußeren Metallhülle 2 weist das Schutzhaus auch eine innere Metallhülle 13 aus Blechelementen 3 auf, wobei allerdings die durchgehende Metallschicht der Isolierschicht 12 zugewandt ist, während die abgewinkelten Bereiche zum Innenraum zeigen. Zwischen den Stoßstellen. der Blechelemente, das heißt zwischen den senkrecht abgebogenen Winkelbereichen, sind jeweils Dichtungen 14 angeordnet. Wie bei den äußeren Blechelementen umgreifen die abgewinkelten Bereiche 4, 7 Wärmedämmplatten 15. Wie in Fig. 2 gezeigt, kann im Innenraum eine Verschalung 16 aus Holz oder Gipskarton-Platten oder dergleichen vorgesehen sein.As can be seen from FIGS. 1 and 2, the shelter consists of several layers, the structure for the walls, the ceilings and the floor being the same. The outer layer of the shelter 1 consists of a continuous metal shell 2, which is formed by individually interconnected sheet metal elements 3. The sheet metal elements 3 are bent twice vertically in their edge areas, so that a cross-sectionally U-shaped profile results in these edge areas. The sheet metal elements 3 are connected to one another by screws, rivets, welding or the like on the angle pieces 4 which are bent perpendicularly to the outer shell. An insulating layer 5 with high thermal insulation and mechanical strength, for example rock wool, is inserted into each of the sheet metal elements 3 and is held by the U-profile of the edge regions of the sheet metal elements 3 becomes. The insulating layer 5 held in the sheet metal elements 3 is followed by a further insulating layer 6 made of the same or similar material as the insulating layer 5, the mechanical strength of the thermal insulation material having to be sufficient for the insulating layer 6 to be connected to the surface parallel to the outer surface Sheet metal elements 3 lying kinked edge regions 7 of the sheet metal elements 3 rests, carries itself. The insulating layer 6 is followed by a support structure made of profile supports 8, the supports 8 having a U-profile and being connected to one another by welding, riveting or screwing in such a way that an H-profile results. Of course, beams with other profiles can also be used. Like the other layers 2, 5, 6, the support structure is self-supporting and is not mechanically connected to the insulating layer 6 or the sheet metal elements 3. Thermal insulation panels 9 are inserted into the U-profiles of the supports 8. In the direction of the interior, a further insulating layer 10, a layer of plasterboard 11 and again an insulating layer 12 are provided. Corresponding to the outer metal shell 2, the shelter also has an inner metal shell 13 made of sheet metal elements 3, although the continuous metal layer faces the insulating layer 12, while the angled regions face the interior. Between the joints. of the sheet metal elements, that is, between the perpendicularly bent angular areas, seals 14 are arranged in each case. As with the outer sheet metal elements, the angled areas 4, 7 encompass thermal insulation panels 15. As shown in FIG. 2, a cladding 16 made of wood or plasterboard panels or the like can be provided in the interior.

Die einzelnen Schichten des sandwichartigen Aufbaus der Wandungen sind nicht miteinander verbunden und stehen allein, so daß der Wärmetransport nicht über etwaige Verbindungselemente erfolgen kann. Das für die Schichten 5, 6, 9, 10, 12 und 15 verwendete Wärmedämmaterial hat eine hohe Wärmedämmung und insbesondere im Außenbereich eine niedrige Speicherfähigkeit, wobei in einem bevorzugten Ausführungsbeispiel die Wärmespeicherfähigkeit aller Schichten von außen nach innen zunimmt. Entsprechend wird die Masse von außen nach innen immer größer, beispielsweise ist die Dicke der aus den Blechelementen gebildeten inneren Metallhülle 13 größer als die der äußeren Metallhülle 2. Die Stoßstellen zwischen den Blechelementen der inneren und äußeren Metallhülle 13, 2 sind versetzt zu den Trägern 8 des Stützenwerks angeordnet, so daß auch die heißen Zonen versetzt sind. Aufgrund der einzelnen Blechelemente 3 ergibt sich ein modularer Aufbau, so daß die Größe des Schutzhauses 1 durch das Vorsehen einer größeren oder kleineren Anzahl von Blechelementen 3 und entsprechend von Trägern 8 des Stützenwerks verändert werden kann.The individual layers of the sandwich-like structure of the walls are not connected to each other and stand alone, so that the heat transfer cannot take place via any connecting elements. The thermal insulation material used for the layers 5, 6, 9, 10, 12 and 15 has a high level of thermal insulation and, in particular in the outer region, a low storage capacity, with the heat storage capacity of all layers increasing from the outside inwards in a preferred exemplary embodiment. Correspondingly, the mass increases from the outside inwards, for example the thickness of the inner metal shell 13 formed from the sheet metal elements is greater than that of the outer metal shell 2. The joints between the sheet metal elements of the inner and outer metal shell 13, 2 are offset from the supports 8 the support structure arranged so that the hot zones are offset. Due to the individual sheet metal elements 3, there is a modular structure, so that the size of the shelter 1 can be changed by the provision of a larger or smaller number of sheet metal elements 3 and correspondingly by supports 8 of the support structure.

Wie aus Fig. 1 zu erkennen ist, ist ein Zuführungsrohr 17 für eine CO2- oder Halon- und so weiter Löschanlage Vorgesehen, das durch die einzelnen Schichten hindurchragt. Das Zuführungsrohr ist mehrfach umgelenkt und ist in den Außenschichten 2, 5, 6 von einer Manschette umgeben, die mit Brandschutzmaterial ummantelt ist. Im Brandfall schäumt das Brandschutzmaterial auf und bildet eine sichere Abdichtung zwischen metallischer Außenhaut 2 und Isolierschichten 5, 6.As can be seen from FIG. 1, a feed pipe 17 is provided for a CO 2 or halon and so on extinguishing system which projects through the individual layers. The feed pipe is deflected several times and is surrounded in the outer layers 2, 5, 6 by a sleeve which is covered with fire protection material. In the event of a fire, the fire protection material foams up and forms a secure seal between the metallic outer skin 2 and the insulating layers 5, 6.

Das Schutzhaus ist durch eine durch eine Tür 18 abschließbare Öffnung begehbar. Die Tür 18 ist in Fig. 3 näher dargestellt. Sie besteht entsprechend der inneren und äußeren Metallhülle 2, 13 aus den Blechelementen 3 mit eingesetztem Wärmedämmaterial, wobei zwischen der inneren und äußeren Schicht der Dicke der Wandung und somit der Tür entsprechende miteinander verbundene Brandschutzplatten vorgesehen sind. Zur besseren Abdichtung ist die Tür mehrfachgefalzt, wobei an der Stelle 19 die Falzung derart ausgebildet ist, daß sich eine Höhlung 20 ergibt, in der eine Dichtung 21 angeordnet ist. Eine Stahllippe 22 drückt im geschlossenen Zustand der Tür 18 gegen die Dichtung 21. Der Türbeschlag zum Öffnen und Schließen der Tür 18 ist im Innenraum angeordnet und weist, wie aus Fig. 3 zu erkennen, einen Schwenkhebel 23 und einen Lenkhebel 24 auf. Der Lenkhebel 24 verhindert das anfängliche Ausschwenken der Tür und gewährleistet ein paralleles Herausfahren, bis eine Schwenkung der Tür 18 möglich ist, die aufgrund der Dicke der Tür und ihrer Lagerung nicht von Anfang an durchgeführt werden kann. Wie aus der Fig. 3 zu erkennen ist, beschreiben die Hebel 23, 24 unterschiedliche Bewegungsradien. Die Stellung der Hebel bei vollständig geöffneter Tür 18 ist strichpunktiert dargestellt. Der Schwenkhebel 23 führt eine Schwenkbewegung von 90° aus, während der Lenkhebel 24 einen kleineren Schwenkwinkel beschreibt. Der Lenkhebel 24 ist länger als der Schwenkhebel 23 und die Drehpunkte des Lenkhebels 24 liegen in Bewegungsrichtung vor den Drehpunkten des Schwenkhebels. Außerdem sind die Drehpunkte der Hebel 24, 23 auch seitlich versetzt.The shelter is accessible through an opening that can be closed by a door 18. The door 18 is shown in more detail in FIG. 3. Corresponding to the inner and outer metal sheaths 2, 13, it consists of the sheet metal elements 3 with inserted thermal insulation material, with corresponding interconnected fire protection plates being provided between the inner and outer layers of the thickness of the wall and thus the door. For better sealing, the door is folded several times, the fold being formed at point 19 in such a way that a cavity 20 results, in which a seal 21 is arranged. In the closed state of the door 18, a steel lip 22 presses against the seal 21. The door fitting for opening and closing the door 18 is arranged in the interior and, as can be seen from FIG. 3, has a pivot lever 23 and a steering lever 24. The steering lever 24 prevents the door from initially being pivoted out and ensures that it can be moved out in parallel until the door 18 can be pivoted, which cannot be carried out from the start due to the thickness of the door and its mounting. As can be seen from FIG. 3, the levers 23, 24 describe different radii of movement. The position of the levers when the door 18 is fully open is shown in broken lines. The pivot lever 23 carries out a pivoting movement of 90 °, while the steering lever 24 describes a smaller pivot angle. The steering lever 24 is longer than the pivot lever 23 and the pivot points of the steering lever 24 are in the direction of movement before the pivot points of the pivot lever. In addition, the fulcrums of the levers 24, 23 are also laterally offset.
