Description

security Zone

The invention relates to a security room for fire protection ins¬ special information technology devices with modular areas over respective Verbin¬ areas composed of side wall elements Sei¬ tenwänden in which a door is inserted, and of ceiling elements zu¬ sammengesetzter ceiling, the side wall elements and the Deckenele¬ Elements are formed cassette-like with arranged on the flat outer sides Kasset¬ tenblechen and embedded between them heat-resistant fire-resistant filling material and adjacent side wall elements and adjoining ceiling elements are connected to each other in shock.

Such a security room for information technology facilities is given in DE 198 52 927 B4. In this known security room, the side walls and the ceiling are each made of fireproof individual elements. composed in a modular manner. The individual elements are cassette-like with cassette panels on the outer sides and interposed received fire-resistant filling material, which prevents fire in eg over 90 Mi¬ grooves that increases the temperature inside the room on the function of information technology facilities endangered values. The individual elements are easy to handle during assembly and make it possible in a simple manner to set up rooms of different sizes according to the wishes of the user, for example within a given building space. To connect the individual elements are bent on the outer coatings to the outside, upwardly conically converging Verbindungs¬ elements attached to the upwardly tapering closure elements are pressed like a clip, so that the individual elements are pressed with her schma¬ len abutting surfaces on interposed seals. This requires appropriate installation measures, which also pay attention to a reliable seal. A similar security space is also shown in DE 198 52 724 C2, are made in the details of the seal.

Another safety space of this type is disclosed in DE 201 20 706 U1, wherein more detailed statements are made on the structure of the layered filling material and for the connection of the side wall elements in the bottom area to floor panels and for the execution of floor elements.

The invention has for its object to provide a security room of the type mentioned, which offers advantages in the installation and for a fire-proof seal. This object is achieved with the features of claim 1. It is provided that the connecting regions are formed in the Stoßbereϊchen as a tongue and groove connection, wherein the cassette sheets of both outer sides for forming the groove on a longitudinal side of the side wall elements and Decken¬ elements project over the filler and for forming the spring on the opposite longitudinal side with the filling material, if appropriate with aufge¬ introduced sealant substantially complete or slightly set back and wherein the strength of the groove and the strength of the spring are matched to fit snugly mating.

The groove-and-tongue connection thus constructed results in a simple, unambiguous assembly of the individual elements (side wall elements or ceiling elements), wherein e.g. the flat joints are already covered during assembly on the two outer sides parallel to these. These measures result in extended sealing possibilities, wherein sealing means can also be inserted between the joints of the individual elements or the filling material can directly adjoin one another and be pressed against one another. Alternatively or additionally, fire-resistant and / or moisture-proof sealing means can be introduced between the lateral tongue and groove areas.

Advantageous embodiments for the production and fire protection function as well as the assembly consist in that the groove by a bend of both opposing cassette plates outward approximately along der¬ the edge of the filling material to adjust their clearance to the thickness of the corresponding Kasset¬ strength of the spring adapted or that the spring by a bend of both opposing cassette sheets inside about in an area corresponding to the groove depth before the edge of the filling material is adapted to the clearance of the inner sides of the cassette sheets corresponding clear width of the groove. In the second alternative, there results a surface-flush transition of the outer sides in the connection region.

A simple, secure locking of the assembled individual elements is achieved in that the groove and the spring over their length on their sides facing each other with one or more spaced apart longitudinally recess (s) on the one hand and one or more on this abge¬ true On the other hand projections are provided which engage in a connected state.

For a simple assembly and a secure, unambiguous fixation thereby contribute to the measures that at least the projections in the insertion direction have an insertion bevel and against the insertion a steep heel or undercut.

A reliable sealing in the connection areas is ensured by the fact that fire-resistant sealing elements and / or watertight sealing elements are arranged as the means of damming in the connection area of the side wall elements and the ceiling elements. In this case, the sealing elements can be arranged between the joints and / or the lateral boundary surfaces of the tongue and groove joint. In particular, between the lateral boundary surfaces, a moisture-proof and / or heat-resistant adhesive can be introduced as the sealing means. In order to avoid electromagnetic disturbances of the devices within the protective space or through them outside the protective space, it is further provided that means for shielding or damping electromagnetic fields are arranged in the connection region of the side wall elements and the ceiling elements. Here, an advantageous measure is that the shield is formed by galvanic connection in the connection area between tongue and groove. This ensures, for example, in case of fire protection against electromagnetic interference.

For the stability of the construction, the measures contribute to reinforcing longitudinal ribs being arranged on the interior side of the side wall elements and / or the ceiling elements, wherein the ribs are preferably arranged in the connection region.

Further advantageous measures for mounting and protection result from the fact that in the corner regions between the side wall elements and / or side wall elements and the ceiling elements a corner joint is formed in the manner of a tongue and groove connection, wherein the spring according to the spring according to claim 1 or 2 and the groove are formed by a U-rail open to the spring and / or a U-shaped notch on the facing portion of the inner cassette sheet or bends on both cassette sheets.

In this case, the functionality of the security space is supported by the fact that the corner joint is also provided with sealing means and / or an electromagnetic shielding. A reliable connection in the corner regions is ensured by providing the corner connection for locking with projections and recesses in accordance with claims 3 or 4.

The corner areas between the ceilings and side walls can be designed accordingly, as the corner areas of the side walls. Another possibility for connecting the ceiling elements to the side wall elements is that, for connecting the ceiling elements to the side wall elements, the ceiling elements placed on the associated upper end sides of the side wall elements terminate flush with the end sides of the flat outer sides of the side wall elements and the end faces at the adjacent end portions of the flat outer sides is connected by means of a Klam¬ meranordnung.

The invention will be explained in more detail with reference to exemplary embodiments with reference to the drawings. Show it:

FIGS. 1 a) to d) show a security space composed of a plurality of side wall elements 1 and cover elements 2 in a modular manner, wherein a door 3 is installed in a side wall. On the underside, the safety chamber has a fire-proof floor 4, which is bordered laterally by the side wall elements 1. The side wall elements 1 extend integrally from the floor 4 to the ceiling, wherein the ceiling elements 2 rest on the upper end faces of the side wall elements 1 and with these are connected. The width of, for example, integrally between two parallel side walls extending ceiling elements 2 correspond to the Ab¬ closing elements of the width of the associated side wall elements 1, while, for example, the front cover of FIG. 1 d) is wider than the front left side wall element and with its front longitudinal side is flush with the Außen¬ side of the front side wall. Accordingly, the rear cover element 2 is executed. As can be seen, for example, from FIG. 1 c), sidewall elements 1 of different widths can also be provided in order to build intermediate sizes of different widths or lengths of safety spaces in a type of modular system.

The connecting regions 12 between the side wall elements 1 below each other, the ceiling elements 2 with each other and between the Seitenwandele¬ elements 1 and the ceiling elements 2, ie the wall-ceiling connection 13, and also the corner joints 14 of the side walls are designed in a special way, as in the Fig. 2 to 7 is shown. FIG. 2 shows a connection region (detail X according to FIG. 1 c)) of two side wall elements 1. As can be seen in particular in connection with FIGS. 6 and 7, the side wall elements 1 and correspondingly also the ceiling elements 2 are joined together in the connecting area 12 along their longitudinal sides in a kind of tongue and groove construction at the abutment points, the construction of the Einzelele¬ elements, ie the side wall elements 1 and ceiling elements 2, from Kassetten¬ sheets 1 1 on their flat outer sides and interposed, for example, glued, fire-resistant, optionally stratified fire-resistant filling material is used. On one longitudinal side of the side wall elements 1 or ceiling elements 2 are on the outside, ie with respect to the security space on the In¬ nenseite and its outside arranged cassette sheets 1 1 on the shock-side edge of the filling material, such as a mineral wool core, with which they are glued before and form a cross-sectionally U-shaped groove in the connection area 12. On the opposite longitudinal side, the cassette sheets 1 1 on the two outer sides substantially close off with the filling material or an optionally applied sealing means and form a spring. In order to adapt the tongue and groove in their strength to each other, the cassette plates 1 1 either in its groove area approximately along the edge of the filling material to the outside cranked (see, for example, Fig. 7, crank 12.4) and smooth in the groove 12.1 or in the Area of the groove 12.1 inwardly ge crests and smooth in the spring, so that the tongue and groove can be fitted together accurately and the lateral inner surfaces of the groove lie smoothly against the lateral outer surfaces of the spring. On the inside of the lateral protrusions 12.2 of the groove 12.1 a plurality of equidistantly spaced apart projections 12.3 are formed over the longitudinal extent of the connecting portion 12, while on the outer sides of the spring in the projections 12.3 corresponding intervals recesses 12.5 are arranged, which are connected to the shape of the projections 12.3 are complementary. In the depth direction of the groove 12.1 and the spring, the projections 12.3 and the recesses 12.5 are coordinated so that the abutment surfaces of Seiten¬ wall elements 1 and ceiling elements 2, if necessary, with the interposition of a seal 15 adjacent to each other, whereby a certain contact pressure can be effected. In the insertion direction, the projections 12.3 advantageously have chamfers, while they are opposite to the insertion direction as well as the Ver¬ recesses 12.2 provided with steep steps for locking-like locking. This results in a gill-like structure. Conversely, the projections can also be arranged on the spring and the depressions on the groove 12.1.

Such as. 2 and 7 also show, in the connection region 12 in the longitudinal direction of the edge, in particular on the inner side of the Sicherheitsrau¬ mes on the cassette sheets 1 1 approximately in the region of the crank 12.4 ribs 12.6 with one or more longitudinally extending rows of holes 12.7 (see. Fig. 7a)) be applied for reinforcement and / or for mounting purposes.

For connecting the side walls in their corner regions, the grooves on the inside of the cassette sheet 1 1 are e.g. formed by notches or folds of one or both cassette sheets 1 1 or by an applied U-profile, in which engages the spring formed in a corresponding manner as described above on the abutting side of adjacent in the corner area side wall element, as shown in FIG. For locking purposes, corresponding projections 12.3 are also arranged on the inside of the groove 12.1 and recesses 12.5 on the outside of the spring, as shown in FIG. 6. Correspondingly, the corner region of the wall-Deckenverbin¬ tion 13 may be executed, as also shown in FIG. 6.

Alternatively or additionally, in the corner region of the wall-Deckenverbin¬ extension 13, as shown in FIG. 5 (detail Y of FIG. 1 b)), outside of the front or narrow longitudinal side of the ceiling element 2 and on the adjacent outer side of Side wall element 1 on the cassette sheet 1 1 conditions by Abkantun¬ or separate application profile strip with ment upwardly on the Deckenele¬ 2 and down to the side wall element 1 projecting Randberei- be mounted on which a cross-sectionally C-shaped retaining profile is aufge¬ pushed, so that there is a stabilizing bracket assembly 16. In the inner corner regions of the wall-ceiling connection 13, angular profiled strips or bends can be attached to the upper sides of the inner cassette sheets 1 1 for stable fixing in order to connect the ceiling elements 2 and the side wall elements 1, eg by means of screws or plug-in elements.

At the joints of the single elements sealing elements 15 can be attached to the fire-resistant seal and / or moisture protection as a sealant. It is advantageous to form at least one longitudinal section of the seal 15 as a foam in the event of fire seal. As a sealant, in particular against ingress of water, it is also possible to carry out bonding in the tongue and groove system of the connection areas.

The tongue and groove connection is optionally designed so that a galvanic connection Ver¬ arises, which results in a defined screening attenuation of the security space against electromagnetic interference.

The wall-floor connection can be carried out stably and clearly by means of a circumferential U-profile, wherein corresponding connection structures can also be arranged in edge regions of floor elements.

Furthermore, the side walls can be provided with fireproof cable sealing devices with D anchtelementen customizable to different cable diameter, as stated in the publications mentioned above. Inside the Safety room can be arranged fire extinguishing equipment and the walls can be equipped with automatic slides.
