Description

The invention relates to a security room for information technology equipment with a fire-proof side wall with a sealed door, a floor and a ceiling, composed of individual elements arranged side by side and connected to each other.

A safe room for information technology equipment is specified in DE-U 77 12 671. This well-known safe room for the fireproof storage of data storage media is a steel structure made of commercial steel profiles, e.g. square tubes, as a scaffolding with angular profiles firmly attached. Steel profiles are fitted with strips on their inner and outer sides of the outer band, plates are mounted on the steel structure via strips with different connectors. Heat bridges are avoided by the displacement of screws, nuts and steel clamps (see page 4 above).

EP-A 0 458 560 proposes to construct a room of fireproof elements, the fireproof elements having a metal intermediate layer and a coolant coolant line system attached to it. The line system is embedded in a coolant layer on one side of the intermediate layer and a trickle coolant layer on the other side of the intermediate layer. A supply line is provided for the coolant supply. This structure and the necessary coolant supply make it not a difficult installation.

A room specified in GB-A 504 255 is modular, with the side walls, ceiling and floor made up of individual panels with edges. Each panel has an aluminum frame with an E-shaped cross section. The layer material is, for example, baquelite-impregnated paper. Existing openings are equipped with mosquito nets.

The purpose of the invention is to provide a safe space of the type described at the outset which is easy to construct from the simplest possible parts and which can be easily assembled according to different spatial conditions.

This is achieved by the features of claim 1, which provides that the individual elements are modular, that the corners of the side walls are constructed with individual corner elements, that between the side wall elements, the corner elements and the ceiling elements there are fire-resistant sealing elements, and that the side wall elements, the corner elements and the ceiling elements are fluidly joined together by the sealing elements of the interlocking connecting elements. The modular construction of the fire-resistant space from the side walls surrounding the floor and the decal also allows for simple installation of simple, easily accessible parts, allowing the modules to be built in small proportions according to the different or larger dimensions of the building, and in particular the addition of a large fire-resistant component to the individual walls.

The difficulty of securing and sealing corners is avoided by the fact that the corners of the side walls are constructed with single-piece corner elements.

This avoids damage to the wall elements and ensures a simple and secure connection by arranging fire-resistant sealing elements between the side wall elements, corner elements and ceiling elements and by keeping the side wall elements, corner elements and ceiling elements sealing together by means of compressive connecting elements.

If the width of the individual side-wall elements from the floor to the ceiling is to be in an integer ratio (including 1) to the width of the ceiling elements or vice versa, where in the composite state two longitudinal edges of one or more side-wall elements are curved with two associated longitudinal edges of one or more ceiling elements, the width of the side-wall element or the ceiling element, the widest of the two, if any, forms a basic unit determining the width of the smallest possible building unit. A construction in which the escape of the lengths of the ceiling and the side-wall elements to several elements is repeated in a modular manner is conceivable, but more difficult, where the width of one element or two would not allow the width of the largest room (or the width of the smallest building element or the largest building element), but would also allow the width of the largest room (or the width of the largest room) to be determined by the modularity of the first two elements or the width of the second element, the modularity of the second element would not be possible, and the width of the second element would not be possible, but the width of the largest room would be less advantageous.

The design of a ceiling element so that the length of the ceiling element is an integer multiple (including 1) of the width of the sidewall element, ensures that a unit of space is exactly the same length as a ceiling element and that, in the case of a rectangular or square space, it can be covered by only one ceiling element in the direction of the ceiling element.

For simple construction, measures that the width of the side wall elements is an integer multiple of the width of the floor elements or vice versa are still advantageous.

The fire-resistant construction and insulation with the possibility of protective installation elements is further enhanced by the fact that the floor is a double floor consisting of a lower floor and a spaced upper floor and that both the lower floor and the upper floor are surrounded by the side walls.

Furthermore, for ease of installation and stable construction, the measures are to include the side walls at their bottom in a floor profile attached to a side floor, the side wall elements and the corner elements at their top in L-shaped cross-section at the bottom at the inside and the ceiling elements at their edges adjacent to the side walls complementarily at the top at L-shaped edges, and the edges between the side walls and the ceiling outside covered by the intersections of overlapping angular cladding profiles.

A high fire safety with relatively light and simple construction of the wall elements is supported by the fact that the side wall elements, the corner elements and the ceiling elements are layered with steel outer coatings arranged on their two outer sides and in between with at least two high temperature counter-acting layers inside the room.

The functional equipment of the security room shall be provided for a protected electrical supply by providing a lighting and air conditioning unit inside and by sealing the supply cables inside by means of a fire-resistant cable conduit built into a side wall with a retractable stop frame and elastic insulating modules of different diameters which can be adjusted to cables, and further by providing a fire extinguisher with fire-extinguishing devices distributed in the ceiling, an extinguishing device disposal and a fire-resistant slide and a control device for receiving sensor signals and actuator controls.

The invention is explained in more detail below by means of examples of execution, referring to the drawings. Fig. 1 a perspective representation of a safety area with partially cut-out walls,Fig. 2 a cross-section of a section of the safety area incorporated into an exterior space,Fig. 3a to 3d) various wall elements in perspective,Fig. 4A and 4B a connection area between wall elements in a top and side view,Fig. 5 a support device in a larger safety area,Fig. 6 a gate installation in the cross section,Fig. 7 an interface element in the safety area andFig. 8 a cable connection between the outside and inside of the safety area.

Fig. 1 shows in perspective the essential parts of a fire room 1 as side walls 2 with a door 5, a ceiling 3 and a double floor 4, whereby the side walls 2, the ceiling 3 and the floor 4 are modularly composed of individual wall elements. The room houses various components of information and control technology, an air conditioning unit 12 and a lighting device 7. In the event of a fire, a fire extinguishing system 8 with outdoor, fire-resistant containers and outdoor conduits in the safety room 1 and outdoor electrical outlets in the interior and an outdoor power supply 9 is provided. In addition, an electronic security control system 10 is installed outside a room, while an electrical power supply 11 is installed in the front of the room. In addition, an electrical power supply 6 can be installed inside the room.

Figures 3a to 3d show the various wall elements in the form of a sidewall S, an equal-width ceiling D, a floor B and a corner E, the side parts of which are preferably the width of a sidewall S. Figures 2, 4A and 4B show the structure of these wall elements in the cross section and their connecting area. The sidewall S and the ceiling D and, accordingly, the corner E elements consist of an outer layer 2.1 and 3.1 of steel sheet, by forming a cassette-like structure and several layers I, II and III of insulation are placed between the two outer layers 2.1 and 3.1 respectively, which has a fire-resistant effect in such a way that the maximum permissible fire exposure in the event of an accident does not exceed 90 minutes.

The corner area between the sidewall elements S and the ceiling elements D is covered by an angular cladding profile 2.2 with the vertical downward leg of the cladding profile 2.2 extending over the connection point between the sidewall elements S and the ceiling element D. The intersecting edges of the sidewall element S and the ceiling element D are complementary L-shaped, so that the sidewall elements S and the ceiling elements D can be easily and clearly assembled with good sealing. Between the longitudinal sides of the sidewall S and the ceiling elements 2.2 are seals with a critical connecting component in the middle of the cross section, with a density of 2.5, since the outer seals are also arranged between 2.7 and 2.6 W. The additional seals are placed between the two sides of the cladding with a density of 2.7 and 2.6 W. The seals are also designed to provide a critical connecting component in the middle of the cladding.

For easy and secure adhesion of the wall elements in the transition areas, connecting elements 2.9 are formed on the outer layer 2.1 with open nuts on the sides, which converge conically upwards, as shown in Figures 4A and 4B. On the connecting elements 2.9 appropriate, upwards-rejuvenating closing elements 14 are pressed, which interfere with the nuts, so that the sealants are compressed and a tight connection is formed. Preferably inside, the connecting points with the connecting elements 2.9 and the closing elements 14 are interconnected between the individual wall elements by means of a transverse-shaped lining 15 profiles.

As can be seen from Figure 2, the side wall elements S are anchored in the external floor by means of U-shaped floor profiles 2.3 fixed in cross section, which keep the side wall elements S securely and easy to install. The ceiling elements can in turn be additionally fixed to the room-side ceiling by means of brackets 3.2. The floor 4 formed as a double floor consists of a lower floor 4.3 and a separate floor 4.1 fixed to it by means of connectors 4.2, and is surrounded by the upper side walls 2 in total, so that good insulation and fire protection are also ensured in this area. The direction of attachment 7 can also be arranged between the lower floor 4.3 and the lower floor 4.1 as shown in Figure 1 instead of an additional decantation in the interior of the ceiling, as shown in Figure 3.1, and a cable can also be placed between the two sides 7.1 and 5.

For tight and fireproof closing of door 5 a 5.3 seal is fitted around the door in doorways 5.1, 5.2 and the door is fitted accordingly and constructed with fireproof materials.

Figure 5 shows the support of the interlocking ceiling elements D by means of a supporting profile 17 below the connecting point and a supporting support 16 below it on the floor, which is anchored by means of a head plate 16.1 to the supporting profile 17 and by means of a foot plate 16.2 to the outer floor.

The cable inlet 6 shown in Figure 1 can be constructed in accordance with the cable inlet 19 shown in Figure 8. It has an outer stop frame 19.2 in which the sealing modules 19.1 are inserted for the respective cables. The stop frame is radially narrowed after installation by tightening screws so that the sealing modules 19.1 are compressed. The sealing modules 19.1 contain double-layered shells so that they can be adapted to different cable diameters.

The measures described above make it easy to assemble safety spaces of different sizes in a modular way, with a set of simple components for easy storage.
