Description

The invention relates to a security room for information technology systems, which is composed of several modules such as side and / or ceiling parts, a sealing means being arranged between the modules and the modules being pressed against one another by at least one connecting means.

Today, large companies are starting to have their own security rooms built for storing large and / or sensitive digital data and hosting computer programs, in which information technology systems (IT systems) protect against external influences such as fire, water or increased humidity or aggressive gases are at least temporarily protected. This makes it possible, for example, to control production processes via an IT system even if a fire has broken out outside an area of a security room.

For the purpose mentioned above, security rooms must meet certain requirements, in particular with regard to a maximum permissible relative humidity and a temperature increase in the event of a fire. Relevant criteria are defined in the standards DIN 4102 and EN 1047-2.

Security rooms can be produced economically by connecting several modules, which form a floor, side walls and a ceiling. The use of different modules, in particular with predetermined length and / or width dimensions, allows the dimensions of a security room to be adapted to a given infrastructure. The individual modules are designed to meet the aforementioned standards, although a connection area between the individual modules naturally remains a weak point.

Various solutions for connecting individual modules have become known from the prior art in order to enable a modular structure of a security room while complying with the specified and named standards. Let me give you an example DE 198 52 724 A1 , DE 198 52 927 A1 , DE 10 2004 031 824 A1 , DE 10 2008 034 055 A1 or DE 100 65 493 A1 as DE 102 40 701 A1 referenced.

The solutions made in accordance with the prior art have the disadvantage that the connecting elements for connecting individual modules have a complicated structure and, moreover, usually also have to be attached from the outside. The latter is a disadvantage in particular when a security room is to be fitted into a given structural infrastructure and individual modules cannot be connected from the outside. In addition, covers are often required so that a potential weak point can be bridged in the connection area between individual modules. Furthermore, joints cannot be precisely adjusted with the connection techniques mentioned, so that the rooms are larger or smaller than planned or the prefabricated elements do not fit into a given room.

The object of the invention is to eliminate or at least reduce these disadvantages, in particular to provide a security room that can be easily produced, does not require any separate covers in the connection area between individual modules, has joints of adjustable sizes and is only accessible from an inside, i.e. an interior of the security room.

This object is achieved in a security room of the type mentioned above if a receptacle for a tension bolt held in the second module is provided in a first module, the tension bolt engaging in the receptacle with tensile strength and by a tensioning means while pressing the first module onto the second module moved towards the second module and fixed in this position.

One advantage achieved with the invention is to be seen in particular in the fact that a safety room is provided which not only meets the standards, but can also be easily produced. In particular, the safety space can only be built up from an inside, because it is sufficient that the clamping means is only accessible from one side. The clamping means is then expediently actuated from the inside in order to press the first module against the second module. The tension bolt provided, which adjusts the first module towards the second module or presses it against it, is then fixed in this position. At the same time, a joint width can also be set within a certain tolerance. This makes it possible, when building the To react flexibly to a given structural infrastructure. In addition, no separate covering of a joint is required.

It is preferably provided that the tension bolt is formed with an external thread at an end engaging the receptacle and the receptacle has an internal thread, the internal thread being continuously interrupted in the longitudinal direction at several points by a smooth section, preferably two at an angle of 180 ° Sections offset from one another, with a free radius in the smooth section being greater than in the area of the internal thread. This makes it possible for the tension bolt to be inserted into the receptacle during assembly of the safety room or a connection of two modules and to latch into it, but without being able to be pulled out of it again. The internal thread or a threaded part can in particular be mounted in a conical seat that widens in the insertion direction against a spring force acting against the insertion direction, so that the internal thread virtually opens when the tension bolt is inserted, but then locks the tension bolt in the opposite direction; the tension bolt can then only be unscrewed by turning. For this purpose, the internal thread in the area of the straight sections has almost continuous slots along the length so that the internal thread can open when the tension bolt is pushed in. The special type of internal thread with the interruptions brings the necessary freedom to allow the tension bolt to snap into the receptacle with tensile strength. As mentioned, the pulling bolt can then no longer be pulled out, but in the event of dismantling, the pulling bolt can be loosened from the receptacle by turning it.

The receptacle is preferably designed as a receptacle bushing with a cylindrical surface having grooves and a widened end piece. This special structure with grooves and a widened end piece is used to be able to fix the receptacle as well as possible in the first module with a material such as plaster by maximizing the surface of the receptacle or it cannot be easily pulled out of the surrounding plaster material.

The tension bolt is preferably displaced and fixed by a tensioning screw as a tensioning means, which penetrates into the tension bolt while engaging in an internal thread of the same. For this purpose, the tension bolt has an opening through which the clamping means penetrates vertically and engaging in the internal thread and, by means of a suitable mechanism, moves the tension bolt together with the first module attached to it towards the second module during tensioning.

Furthermore, it is preferred that the tension bolt is mounted in a cylindrical holding and fixing element arranged in the second module, wherein the tension bolt penetrates the holding and fixing element perpendicular to its longitudinal axis in the area of two openings, and a clamping screw is provided which passes through an opening of the tension bolt runs, and the holding and fixing element has a beveled surface on which the clamping screw slides for or when pressing the first module and thereby moves the tension bolt and the first module towards the second module. In this way, a particularly simple assembly of two modules is possible. In a first step, the tension bolt is locked in the first module. In a second step, the tension bolt together with the first module hanging on it is pulled through the tensioning screw towards the second module by screwing in the tensioning screw or the first module is pressed against the second module. At the same time, the tension bolt moves into the first module. In this context, it can also be provided that the tension bolt has a knock-in locking pin or a screw-in locking screw at an end that does not engage in the receptacle, so that the tension bolt can be displaced through the openings. The locking pin or locking screw is used when inserting the tension bolt and locking the first module so that the tension bolt cannot move into the second module during this step. As soon as the first module is locked, the locking pin is driven in or the locking screw is screwed in, so that the tension bolt can now be moved through the openings during tensioning.

The sealant is elastic. In particular, commercially available fire protection waterstops that are pre-compressed and automatically expand after assembly can be used as sealing means. Due to this effect, the fire protection tapes absorb building tolerances in a joint width and a tight joint is always guaranteed. The fire protection waterstops prevent water vapor or harmful gases released in the event of a fire from entering the security room and thus preventing the requirements for humidity and temperatures from being met. No further sealing is required.

The modules consist of sheet steel on the outside and an insulating material is arranged between the sheet steel. This means that the required fire resistance can be ensured in the area of the individual modules. In this context, it is particularly expedient that two different insulating materials are provided in mutually adjacent layers. A first insulating material, which is arranged on the outside, can be formed from a mineral foam sheet, while a second insulating material, which is arranged on the inside, is formed from a polyurethane foam. For permanent fixation, the first insulating material and the second insulating material can each be glued to a steel sheet.

As already mentioned, it is advantageous that the clamping means is accessible only from an inside of the safety room, so that assembly or dismantling can also be carried out accordingly from an inside of the safety room.

Further features, advantages and effects of the invention emerge from the exemplary embodiment shown below. In the drawings, to which reference is made, show in cross-sectional representation:

• Fig. 1 a representation of two partially shown side wall modules of a security room before connecting;
• Fig. 2 in the Fig. 1 modules shown in connected state;
• Fig. 3 a module of a side wall that is connected to a module of a ceiling.

In Fig. 1 parts of a security room 1 are shown prior to joining. The security room 1 is made up of several modules 2, 3, which form side walls, as well as corresponding modules in the floor and ceiling area. Furthermore, the security room 1 comprises a door in the area of at least one side wall.

In Fig. 1 the modules 2, 3 of the security room 1 are shown in a situation before they are connected. A first module 2 comprises a steel sheet 21 on the outside, which comprises the edges of the module 2 located on the end face. Between the steel sheet 21 or, if necessary, several opposing steel sheets 21 are two insulating materials 22, 23 arranged. A first insulating material 22, which is arranged on the steel sheet 21 towards an outside 27 of the security room 1, consists, for example, of a mineral foam board. A second insulating material 23, which is arranged on the steel sheet 21 towards an inside 26 of the security room 1, advantageously consists of a polyurethane foam. The insulating materials 22, 23 essentially completely fill a space between the steel sheet 21 or a plurality of steel sheets 21 and are matched to one another in terms of their composition or constitution and expansion in such a way that optimal fire protection security is provided in the area of the inside 26 of the security room 1. Both insulating materials 22, 23 can be glued to the steel sheet 21. Other types of connection are of course also possible. In addition, the insulating materials 22, 23 can also be connected to one another, for example by gluing. A second module 3 has an analogous structure with regard to the insulating materials 22, 23 and the steel sheet (s) 21.

In the first module 2, a receptacle 5 designed as a receptacle socket is fixedly arranged on the front side. The receptacle 5 is advantageously formed from a metal, in particular from a steel. The shape of the receptacle 5 is initially formed over large parts with a cylindrical surface 10 which has a plurality of parallel ribs, not shown. At the end, the receptacle 5 has an end piece 11 that is wider than the cylindrical surface. The grooves of the cylindrical surface 10 or the end piece 11 engage in the second insulating material 23 on the one hand. On the other hand, a plaster of paris material 24 is provided in an opposite region, which comprises the spaces between the cylindrical surface 10 and the end piece 11 formed by the ribs. This ensures that the receptacle 5 is held securely in the first module 2 even under high tensile loads. Although not shown, it can also be provided in this regard that the steel sheet (s) 21 on the end face partially extend over the receptacle 5 in order to additionally ensure a secure hold of the receptacle 5 in the first module 2.

A holding and fixing element 12 for a tension bolt 6 is arranged in the second module 3, the tension bolt 6 being able to interact with the receptacle 5 of the first module 2. At an end 7 engaging in the receptacle 5, the tension bolt 6 has a continuous external thread 8. This external thread 8 of the tension bolt 6 can engage in an internal thread 9, not shown in detail, of the receptacle 5. The Internal thread 9 or an inside in the area of a free opening of the receptacle 5 is designed such that the internal thread 9 is only partially formed. Such a partial formation can be done, for example, in that the internal thread 9 is interrupted at two points along a longitudinal axis of the receptacle 5 or the receptacle bushing and is designed in these areas with smooth sections, which are preferably offset from one another by 180 ° and have a larger free radius, viewed from the longitudinal axis of the receptacle 5, as the internal thread 9. This enables the tension bolt 6 to engage in the internal thread 9 of the receptacle 5 and thus be anchored with tensile strength, but can only be released from the receptacle 5 by turning, but not by simply pulling it out.

The tension bolt 6 is mounted in two lateral openings 13, 14 in the holding and fixing element 12, which is essentially cylindrical and runs with a cylinder axis perpendicular to the longitudinal axis of the tension bolt 6. The tension bolt 6 has an opening 17 with an internal thread through which a clamping screw 16 protruding through an upper opening 15 extends while engaging the internal thread of the tension bolt 6. The end of the holding and fixing element 12 has a beveled surface 18 on which the clamping screw 16 rests. Furthermore, a locking screw 20 is provided on a non-engaging end 19 of the tension bolt 6. On the end face of the second module 3, an elastic sealing means 4 is arranged, which consists in particular of a commercially available fire protection joint tape.

The holding and fixing element 12 of the second module 3 is surrounded on one side by a plaster of paris material 24, which closes off with the sheet steel 21, similar to what is the case in the first module 2 for the receptacle 5.

At the in Fig. 1 the situation shown, the two modules 2, 3 are spaced from one another. In a first step of the connection, the first module 2 is placed against the second module 3 or vice versa, so that the tension bolt 6 engages in the receptacle 5 and engages in it. The two modules 2, 3 are then locked and cannot easily be detached from one another without, however, the sealing means 4 still being compressed or the modules 2, 3 being pressed against one another. During this process, the securing screw 20 serves to prevent undesired displacement of the tension bolt 6 into the first insulating material 22 of the second module 3, which would lead to a shortening of a clamping path. After the two modules 2, 3 have been coupled to one another, the locking screw 20 is screwed into the tension bolt 6 so that it can be displaced through the opening 13 into the first insulating material 22 of the second module 3. Then the clamping screw 16 is screwed into the opening of the tension bolt 6 or a corresponding internal thread in the same and strikes the beveled surface 18, which causes a displacement of the tension bolt 6 in the first insulating material 22 of the second module 3 and thus a displacement of the first Module 2 leads to the second module 3. As a result, the in Fig. 2 The final state shown is reached, the two modules 2, 3 being firmly connected to one another. To cover the holding and fixing element 12, a stopper 25 can be provided, which consists of the same material as the second insulating material 23, at least in the interior, and is attached in the direction of the arrow.

Like, for example, from Fig. 2 As can be seen, two modules 2, 3 can be connected exclusively via an inside 26. Thus, individual modules 2, 3 can be placed directly on a wall in a given building object and yet firmly connected to one another. For this purpose, appropriate connections are arranged approximately every 60 to 80 cm on the contact surfaces of the modules 2, 3. A corresponding connection can also be established between a first module 2 and a second module 3 designed as a ceiling module, which is shown in FIG Fig. 3 is shown as an example. In this case, the procedure can be analogous to connecting modules 2, 3 of a side wall, with individual modules 2, 3 again being able to be connected exclusively from an inside 26. Additional external covering of the joints is not required.
