Abstract

The invention relates to a fire protection profile and room temperature cell elements with such fire protection profiles.

Description

The present invention relates to a fire protection profile, a room temperature cell element with such fire protection profiles and their use.

background

Due to changes in fire protection standards and increased structural requirements for fire protection, it is necessary to comply with the new requirements of the standards. At the same time, it is important to save weight and material. The particularly sensitive parts of walls, floors or ceilings are always the abutting edges and element connections with one another and the cracks formed here with one another. This is where the risk of a fire spreading is greatest. Therefore, these abutting edges in corner areas or also in flat areas, i.e. if several elements are arranged flat on one another, must be protected, stabilized and sealed against the escape of fire and gas.

Task

It is therefore the object of the present invention to provide a fire protection profile which is particularly simple and can be installed quickly during the manufacture of room temperature cell elements. Furthermore, it is the object of the present invention to provide a room temperature cell element with the highest possible weight and material savings compared to known fire protection components.

Solution

This object is achieved with the main claim 1 and the subordinate claims 4 and 9.

The core idea of the present invention lies in the special design of the fire protection profile shown here for the first time. The invention describes a fire protection profile for providing in the area of abutting edges of individual room temperature cell elements, the fire protection profile having at least one band element, within which an inorganic fire protection element is at least partially arranged, the fire protection element being plate-like and flattening at least towards a first end face.

Different materials can be selected as the strip element, which are designed to be significantly thinner in terms of their material thickness than in terms of their material length. Consequently, a band shape results.

This band shape is advantageous because it makes it particularly easy to produce the required final shape for later installation. In addition, the at least one strip element can be correspondingly shaped, for example bent, in its longitudinal direction, so that it can be at least partially adapted to the shape of the at least one inorganic fire protection element.

Furthermore, the fire protection profile has at least one inorganic fire protection element, which is designed to be at least partially receivable by the strip element. The combination of band element and fire protection element ensures a significantly higher fire resistance, especially abutting edges, than is the case with currently common fire protection components.

Furthermore, it has been shown that the plate-like design of the fire protection element, which is designed to flatten at least towards a first end face, can be installed particularly easily.

The plate-like design is advantageous because it allows a fire protection volume to be provided which is designed to be flame-retardant and/or non-combustible. In addition, the plate-like design can be built into the future room temperature cell elements in a particularly simple manner without losing too much volume that cannot be filled with insulating foam.

If the fire protection element were to be too thick, this would have the consequence during later installation that too little insulating foam could be introduced into the wall of the room temperature cell element, which would increase the requirements for cooling capacity and temperature maintenance of the later room temperature cells, such as cold rooms, cooling cells, cold cells or other temperature-controlled room cells, can no longer be granted. On the other hand, if the design is too thin, the fire protection properties would be impaired.

The plate-like fire protection element has in simplest training case, but not limited thereto, two substantially parallel opposite side surfaces. These two side surfaces are each delimited by side surface edges. The side surface edges are connected to one another via end faces. This results in the plate shape.

It has been shown to be particularly advantageous for fire resistance if at least one end face, at least partially, of the fire protection element and/or at least one side surface, at least partially, of the fire protection element is arranged within the course of the band element. Thus, the fire protection element is at least partially accommodated by the band element in its course. The band element runs around the fire protection element at least in sections, advantageously at least one end face thereof. In this way, a tape course can advantageously be produced, which at least partially spans the fire protection element. At least one common contact surface can be formed here. However, this is not absolutely necessary, since the type of use of the room temperature cell element, for example as a ceiling element, wall element or floor element of the room temperature cell to be spanned, such as a cold room, cooling cell, cold cell or other temperature-controlled room cells, must be coordinated.

It has proven to be advantageous here if at least one side surface of the fire protection element is designed to be flattened towards a front side. This results in an inclined plane. This flattening geometry in combination with the band element running essentially on the outside around the end face and/or inclined plane has proven to be particularly advantageous in the later arrangement in one Room temperature cell element shown. In this case, the insulating foam can backfill and/or partially fill the fire protection profile particularly well, so that it is held stably and reliably in the desired position in the room temperature cell element.

Further advantageous embodiments result from the following dependent claims.

In a further advantageous embodiment, the fire protection element and the strip element can form at least one common contact surface, which is then released again as the process progresses. The course of the band element can also be referred to as a shape path. In the further course of the shaping path, the end face of the fire protection element can be accommodated by the strip element, a distance being provided at least partially between the two elements. This is advantageous because in this way a particularly stable positioning of the fire protection profile and foaming it in during the production of the room temperature cell elements can be achieved when the fire protection profile is subsequently used in room temperature cell elements.

In a further advantageous embodiment, the strip element and the fire protection element can form at least one further common contact surface. The first common contact surface is advantageously formed along a side surface of the fire protection element. The band element rests at least in sections, advantageously completely, on this side surface.

The second common contact surface can be formed at least in sections, advantageously completely, between the band element and an end face of the fire protection element.

This is advantageous for later use of the fire protection profile if it is to be used in accordance with the lock and key principle. In particular, the end face of the fire protection element forms a common contact surface with the strip element at least in sections, advantageously completely, toward which the at least one beveled side surface of the fire protection element is flattened.

In a further advantageous embodiment of the fire protection profile, the strip element can have a tongue-like projection. This is advantageous because a projection without sharp edges and without material interruption can be created in a particularly simple manner. The tongue-like projection is flat in its extent.

In a further advantageous embodiment, the strip element can form at least one common contact surface with itself towards its free end in the direction of a shaping path. The forming path of the band element thus runs through a substantially 180° curve, advantageously a full 180° curve, so that the band element forms a common contact surface with itself. The band element is doubled in this area. This can also be referred to as continuous convolution. The band element forms a tongue in this area. Consequently, the tongue-like projection is formed as a double layer of the band element. However, the band element is not interrupted here. The tongue-like projection is integrally formed from the fold of the band member.

This tongue itself is designed to be flat, that is to say uncurved. The resulting double layer serves the Stabilization of the projection, the seal to another fire protection profile when used later and for improved fire protection behavior of the entire fire protection profile.

Furthermore, this prevents sharp or open edges from remaining as a risk of injury.

If the shape path is followed further after this tongue-like double layer, the double layer opens up again. The strip element undergoes a further curvature, which forms a gradient angle in the range from 75° to 110°, more advantageously 100°, compared to the double layer. The band element thus runs away from the double layer. It has proven to be advantageous here if this further mold path section has a length in the range from 6.5 mm to 15 mm. This is advantageous for the subsequent arrangement of room temperature cell elements on one another, since a contact surface with a further fire protection profile is formed on this steeply rising mold path section in the range from 75° to 110°, more advantageously from 100°.

Finally, the forming path towards the free end of the band element can go through an additional widening curve. This further curvature has an expansion angle in the range from 120° to 140°, more advantageously 130°. This widening angle is advantageous because it allows sufficient free space to be created so that a corresponding fixation can be achieved later when the room temperature cell elements are foamed. Foaming agent, also known as insulating foam, can penetrate at least partially into the resulting free space and harden accordingly. This fixes the fire protection profile. As insulating foam, for example, PUR foam or PIR foam used. Furthermore, this expanded free space makes it possible for the fire protection element to be inserted particularly easily into the already pre-bent band element during assembly. The widening prevents damage to the fire protection element.

In this exemplary embodiment, a side surface of the fire protection element, which can also be arranged at least partially within the shaping path of the band element, is only designed with a simple bevel towards its end face. The fire protection element forms a decreasing wedge shape in the direction of its front side. It has proven to be advantageous here if the wedge shape has a flattening angle in the range from 15° to 45°, more advantageously 30° or more advantageously 18°. It should also be mentioned here that all intervals within the stated range of 15° to 45° are also to be regarded as disclosed. The selected angle of 30° or 18° is particularly advantageous, since this ensures a particularly effective formation of a common contact surface, which can also be referred to here as a contact surface, of the end face and the band element.

In this exemplary embodiment, the band element and the fire protection element are combined with one another to form the fire protection profile. In this exemplary embodiment, this takes place in that the fire protection element is first placed on the already preformed band element with one side surface. A first common contact surface is formed. Here, the fire protection element can be shorter than the band element, which protrudes with its first free end over the non-beveled end of the fire protection element.

However, this is not to be understood as limiting, so that it is also conceivable that the strip element and the fire protection element are of the same length at the ends when in use.

The fire protection element with the wedge-shaped cross section, that is to say with an at least partially flattened side surface, is then guided in the direction of the tongue of the band element. The shortened end face of the fire protection element formed by the flattening forms a stop surface, also referred to as the second common contact surface, with the preformed strip element. The common contact surface is formed between the end face of the fire protection element and the steeply rising section of the strip element in the range from 75° to 110°, more advantageously 100°.

The fire protection profile is formed in this combined state of the band element and the fire protection element. This can then be used in room temperature cell elements to form room cells.

The fire protection profile described in this embodiment can be understood as a "key".

In a further advantageous embodiment, the tongue-like projection can have a length in the range from 8 mm to 9 mm. This length advantageously corresponds to the length of the double layer formed. This length proved to be sufficient in subsequent use to meet the fire protection standard EN 13501-1 "Fire classification of construction products and building elements - Part 1: Classification using the results of fire behavior tests for construction products".

In a further advantageous embodiment, the strip element is designed to widen in a U-shape in the direction of its shaping path towards a further free end. This means that the shape path of the band element has a U-shaped widening course towards the free end of the band element.

The band element is initially designed to run in a straight line. In the further course, a first curvature to the right takes place in the direction of the mold path, so that the planar arrangement is eliminated. The section which follows the first curvature can be understood as the first leg of the U. A substantially vertically extending base connects to the end of the first leg. In turn, the second U-leg is arranged subsequent to this. The shape path goes through another curve to the second leg of the U. The base of the two legs spans an expanding U-shape.

This embodiment variant can be understood as a lock.

In the simplest case, the two legs of the U are designed symmetrically to one another.

In this embodiment, the fire protection element can be flattened on both sides toward its free end. The lateral cross-section of the fire protection element is designed in a distorted V-shape with a widened base.

In the simplest case, the flattening on both sides is formed symmetrically, so that a flattening angle of the side surface is formed in the range from 15° to 45°, more advantageously 30° or more advantageously 18°. It should also be mentioned here that all intervals are within the stated range 15° to 45° are also to be regarded as disclosed. Precisely the selected angle of 30° or 18° is advantageous, since this can ensure a particularly effective arrangement of the resulting end face against the band element.

This is not to be understood as limiting, so that it is also conceivable for the two flattened areas to have different inclinations and lengths.

The band element and fire protection element are combined to form the fire protection profile. In this exemplary embodiment, this takes place in that the fire protection element is first arranged on the band element. A first common contact surface is formed. In this case, the fire protection element can be made shorter than the band element, which protrudes with its first free end over the non-beveled end of the fire protection element. Here, too, this is not to be understood as limiting, so that it is also conceivable for both elements to be of the same length when in use.

The fire protection element is then guided against the base of the widening U-shape of the band element. This creates the second common contact surface. The fire protection profile is formed.

In this embodiment of the fire protection profile, the two bevels of the fire protection element formed by the flattened areas are exposed. There is no common contact area between the slopes and the band element. This is also an advantage for the later installation, since this creates scope to facilitate the installation of the fire protection profile in room temperature control cells.

Due to the free volume created between the slope and the band element, the latter can still give way during shoring, so that certain geometric inaccuracies can be compensated for.

In a further advantageous embodiment, a length of the V-shape in the range from 10 to 20 mm has proven to be advantageous. The length of the V-shape of the fire protection element also refers to the adjacent side with reference to the respective flattening angle. In particular, lengths in the range from 10 to 20 mm, more advantageously from 12 mm or from 18 mm, have proven to be advantageous. The length depends on the selected flattening angle. With a flattening angle of the side surface of 18°, the adjacent length is 12mm. With a flattening angle of the side surface of 30°, the adjacent length is 18mm.

This length is advantageous because it allows the subsequent installation and the form fit and/or force fit with other fire protection profiles to be provided easily and safely.

As a result, the fire protection element can be inserted particularly easily into the widening U-shape of the band element. The end face of the fire protection element then forms a common contact surface with the base of the U-shaped strip element. This can also be referred to as a stop surface. Free spaces are formed between the flat areas on the one hand and the two legs on the other hand.

This is of course not to be understood as limiting, so that it is also conceivable that the two U-legs of the band element are designed to have different lengths and/or different degrees of inclination. So can in one further advantageous embodiment form the first leg at an angle of 160 ° to 170 ° compared to the previously flat profile of the band element. The adjoining base is essentially, advantageously completely, aligned vertically.

With reference to this base, the second leg then spans a widening angle in the range of 120°±5°.

In addition, the lengths of the two legs can optionally differ. It is advantageous for sealing abutting edges if the first leg is longer than the second leg. For example, the first leg can have a length in the range from 12 mm to 15 mm. For example, the second leg can have a length in the range from 8 mm to 12 mm. However, they can also be chosen to be of the same length.

In a further advantageous embodiment, the band element can be designed as a C-bend. This is an advantage, for example, in the case of ceiling joints. The forming path of the band element takes a C-shape. First of all, the band element is flat, as in the two above advantageous embodiments.

In the course of the shape path, there is a steep rise in the band element. In relation to the flat strip element, it forms a pitch angle in the range of 65° to 110°, more advantageously of 80°. It has proven to be advantageous here if this further, steep shaping path section has a length in the range from 6.5 mm to 15 mm. This is advantageous for the subsequent arrangement of room temperature cell elements together, since a contact surface with another one is on this mold path section Fire protection profile is formed.

Eventually the molding path to the free end of the band member follows another curve. This last shape path section towards the free end is in turn essentially, advantageously completely, horizontal and thus essentially parallel to the first flat section of the band element. A C-shape results.

In this embodiment, the fire protection element can be flattened on one or both sides. It is important to ensure that the free end of the strip element is in physical contact with the fire protection element and/or is arranged so that it is exposed. The free end of the band element can, for example, abut or rest on the fire protection element. Consequently, the flattening angle and strip element length are matched to one another. The band element length here corresponds to the conceptually drawn adjacent leg described above. The two fire protection elements described above have proven particularly advantageous. To form the fire protection profile, the fire protection element is inserted into the C-shaped pre-bent band element. In this embodiment, there are three common contact surfaces between the fire protection element and the band element.

However, this is also not to be understood as limiting, so that it is also conceivable that the free end of the band element does not form a common contact surface with the fire protection element and ends beforehand. However, the C-shape is retained and as described above.

In a further advantageous embodiment, the fire protection element can have a geometric extension of at least 60 mm in length. The width is predeterminable, so that it is adapted to the finished dimensions of the room temperature control cell element. The strip element advantageously extends completely along the abutting edge of a room temperature cell element. The entire abutting edge of a room temperature cell element is secured with at least one fire protection profile. Fire protection profiles are also advantageously arranged along all abutting edges.

In addition, the fire protection profile extends at least partially along the respective side surface of the room temperature cell element. This is reflected in the length of the fire protection element or the strip element. For easier processing of the fire protection profile in the room temperature cell element, it has proven to be advantageous if, when in use, the band element is longer than the fire protection element.

Furthermore, the present invention relates to a room temperature cell element for the construction of room temperature cells with at least one fire protection profile according to at least one of the preceding claims, wherein the room temperature cell element is plate-like and has at least one inner surface and at least one outer surface, the inner and outer surfaces having a peripheral abutment surface which at the same time connecting the inner and outer surface to each other, are delimited and the at least one fire protection profile according to at least one of the preceding claims is arranged at least partially in at least one abutment surface and/or at least partially along an abutting edge.

In the present case, wall elements for the formation of walls, in particular side and/or partition walls, advantageously ceiling elements, are referred to as room temperature cell element To understand formation of ceilings and advantageous floor elements for the formation of floors of room temperature cells. All of these elements can be used to advantage in the construction of refrigerated cells, cold cells, cold rooms, deep-freeze cells, temperature-controlled room cells and the like.

The room temperature cell element, in particular room wall temperature cell elements and/or room ceiling temperature cell elements, are advantageously constructed in the manner of a sandwich, so that the space spanned between the inner and outer surface of the respective room temperature cell element is designed to be insulated. This insulation is advantageously carried out by means of foaming. This is usually done with PUR foam and/or PIR foams.

The inner surface of the room temperature cell element is to be understood as meaning the surface which faces the room temperature cell interior when the room temperature cell element is installed.

The outer surface of the room temperature cell element means that surface which faces away from the room temperature cell interior when the room temperature cell element is installed and forms the outer surface.

The room temperature cell element advantageously has at least one fire protection profile, as described above.

In the simplest case, the room temperature cell element is flat and has an inner surface and an outer surface. If, for example, a wall is to be formed from a plurality of room temperature control cell elements, a room wall temperature control cell element advantageously has two abutment surfaces which are at the same time inner and outer surfaces connect. The transition from the inner and outer surface to the respective abutment surface can be referred to as an abutment edge.

By providing at least one, advantageously several, fire protection profiles on the abutting edges and/or along the abutting edges and/or at least partially in the abutting surface of a room temperature cell element, its fire resistance at the abutting edges and thus also the fire protection can be significantly increased. This is also promoted by the fact that the at least one fire protection profile is arranged at least partially within at least one abutment surface.

A room temperature cell element can advantageously have more than one abutting surface and thus more than two abutting edges. In order to secure all abutting edges, it has also proven to be advantageous if fire protection profiles are arranged at least partially embedded at the abutting edges and/or at least partially in the abutting surface.

In a further advantageous embodiment, the strip element of the at least one fire protection profile can be arranged so that it is freely accessible from the at least one abutting surface and/or from the abutting edge and/or protrudes and is freely accessible. This is advantageously the tongue-like section of the first embodiment described. The at least one fire protection profile is embedded and foamed in the room temperature cell element. Only the tongue-like section sticks out at the abutting edge. Advantageously, the tongue-like double layer is aligned vertically or horizontally for installing the room temperature control cell element. The entire double layer is freely accessible.

Furthermore, it is also conceivable that a fire protection profile according to the above second and/or also third exemplary embodiment is embedded partially at the abutting edges and/or at least partially in the abutting surface. For example, it is conceivable that the first leg of the widening U-shape is arranged on the outside of the abutting edge and/or the abutment surface. It is also conceivable that the base of the C-bend in the third embodiment is also arranged on the outside of the abutting edge and/or the abutment surface. Consequently, the respective band elements are freely accessible.

The abutment surface is advantageously to be understood as the surface which forms the side surface of the room temperature cell element and which is placed and connected to a further surface of a room temperature cell element in abutment during subsequent installation. The resulting surface when installed is referred to as the impact surface.

In a further advantageous embodiment, the room temperature cell element can be foam-filled, with the fire protection profiles being foamed in at least partially. This is an advantage because the fire protection profiles are fixed directly in the correct position to be secured. This means that there can be no slipping during installation. Fire protection can therefore be implemented very easily. By at least partially foaming and/or backing the fire protection profiles, they can be secured in their position. It has proven to be particularly advantageous if the fire protection profiles are arranged at and/or along the abutting edges and/or at least partially in the abutting surface at mutually corresponding positions in each room temperature cell element. In this way, it can be ensured that when two room temperature cell elements facing each other are butted together the respective fire protection profiles are always arranged opposite one another. Particularly advantageously, the fire protection profiles also form at least one common contact surface in the installed state of two room temperature control cell elements that are opposite one another and are placed on top of one another. This common contact surface can advantageously be designed as a form fit and/or as a force fit and/or as a friction fit. This again improves and increases the fire resistance.

In a further advantageous embodiment, the at least one fire protection element can be arranged at least partially below the inner surface and/or outer surface of the room temperature cell element. Advantageously, the abutting edge of two abutting room temperature cell elements is designed to be fire-protected both on the inner surface and on the outer surface with at least one fire protection profile. This is particularly advantageous when flat room temperature cell elements, for example wall elements, are arranged next to one another.

If, on the other hand, a room temperature cell element butts against a solid floor, the room temperature cell element has at least one fire protection profile only on the inner surface, which faces the room to be temperature-controlled. A double fire protection compared to the solid floor is not necessary and creates a cost reduction.

In a further advantageous embodiment, the at least one fire protection element can extend at most along half of the inner surface and/or outer surface. It has been shown that it is not necessary to cover the entire inner surface and/or outer surface of the fire protection element Form extending room temperature cell element. This reduction in fire protection element material means that both costs and significant weight can be saved. The room temperature cell elements can be provided much more easily than with continuously arranged fire protection elements.

It has been shown to be particularly advantageous if the fire protection elements have an extension along the inner surface and/or outer surface of 3 to 45 cm ± 1 cm, more advantageously 6 to 25 cm ± 1 cm, particularly advantageously 15 cm ± 1 cm. This length is sufficient to improve the fire protection class of the manufactured room temperature cell systems and to provide sufficient smoke gas tightness at the abutting edges. In addition, the weight of the individual room temperature cell elements can be significantly reduced. Only the areas around the abutting edges are specially secured. In addition, the length of the fire protection element also depends on the thickness, also referred to as the wall thickness, of the respective room temperature cell element. The wall thickness of the room temperature cell element advantageously corresponds to the dimension from the inner surface to the insulating foam to the outer surface of the respective room temperature cell element. In the case of corner designs, the wall thickness of the room temperature cell element can advantageously correspond to the dimension from the abutment surface to the insulating foam to the outer surface of the respective room temperature cell element.

Regardless of the exemplary embodiments shown here, it has proven to be advantageous to always design the respective fire protection element to be 20mm±5mm shorter than the thickness, also referred to as the wall thickness, of the respective room temperature control cell element. This allows excellent positioning of the entire fire protection profile within the Room temperature cell element are ensured. In addition, there is still sufficient insulation foam so that the insulation of the room temperature cell element can be ensured.

In the simplest case, a room temperature cell element can have four fire protection profiles, which are arranged on and/or along the four abutting edges and/or at least partially in the abutting surfaces.

The fire acceleration, more precisely the critical positions in the fire spread, are mainly in the abutting edges. If these are not adequately sealed, the fire can spread.

It has therefore proven to be advantageous if the abutting edges and the areas around the abutting edges are appropriately sealed and/or reinforced to prevent the spread of fire. Such a provision with fire protection profiles is not necessary on the continuous inner surfaces, ceiling surfaces and/or floor surfaces. There is almost no risk that a fire that has broken out will spread further, since the shell-like band elements also enclose the insulating foam on the inside and thus protect against fire.

By this partial and simple provision of the fire protection profiles described here, high costs can be saved and a weight reduction of the room temperature control cell system can also be brought about.

Furthermore, the present invention relates to a fire-protected room temperature cell system with at least one first and one second room temperature cell element, wherein the two room temperature cell elements are coupled to one another via fire protection profiles arranged on and/or along the abutting edges and/or at least partially in the abutment surface, wherein the fire protection profiles of each room temperature cell element arranged opposite one another have at least one form fit and/or according to the key-lock principle or form a force fit and/or friction fit with one another.

If the sandwich-like room temperature cell elements are to be used to construct a room temperature cell system, then advantageously several of the room temperature cell elements are arranged butt against one another. As a result, walls, ceilings or also the floor and thus the room temperature control cell system as a whole are formed.

If two room temperature cell elements are now to be arranged next to one another, they are first aligned against one another. This can be done, for example, in the case of room wall temperature control cell elements in a vertical orientation. Both room wall temperature control cell elements are initially spaced apart from one another with the respective abutment surface facing one another. In order to successfully butt both room wall temperature control cell elements and form a fire safety device, both room wall temperature control cell elements have at least one fire protection profile on and/or along the respective abutting edge and/or at least partially in the abutting surface.

As already explained above, at least one fire protection profile can be at least partially embedded or foamed in both on the inner surface and on the outer surface of each room wall temperature control cell element.

In order to be able to form a fire-protected joint, it is necessary to provide embodiment variants of the above-mentioned fire-protection profile that are designed to be complementary to one another. The fire protection profiles, which are designed to complement each other, are already positioned and fixed by foaming in during the production of the room wall temperature control cell elements.

Here, for example, a first room wall temperature control cell element with a tongue-like fire protection profile is provided both on and/or along the inner abutting edge and/or outer abutting edge, not to be understood as limiting. The band element folded like a tongue is freely accessible and protruding. The fire protection element itself is foamed inside the room wall temperature control cell element.

The second room wall temperature control cell element is designed in addition to this. On and/or along the inner abutting edge and/or outer abutting edge it has at least one fire protection profile with the U-shaped widening geometry of the strip element.

If both room wall temperature control cell elements are placed in abutment, the tongue-like projection slides from the outside under the first leg of the U-shaped expanding band element. A form fit and/or force fit and/or friction fit is advantageously formed. According to the lock and key principle, sealing of the abutting surface and/or abutting edges underneath is made possible for the first time.

This is not to be understood as limiting, so that it is also conceivable that the first leg reaches underneath a force is applied to the first leg by the tongue-like projection. The U-shaped widening strip element is at least partially deformed by this application of force and under tension is gripped by the tongue-like projection. As a result, a frictional connection is advantageously formed. This is advantageous because the fire protection properties are additionally improved as a result, since the abutting edge can be secured even more tightly.

Of course, the example here with the room wall temperature control cell elements is only to be understood as an example. Instead of the room wall temperature control cell elements, room ceiling temperature control cell elements and/or room floor temperature control cell elements can of course also be used.

A further conceivable combination is, for example, at least partially on and/or along the inner abutting edge and/or outer abutting edge and/or at least partially in the abutment surface, fire protection profiles with a C-fold. When two room temperature cell elements are butt-joined, the fire protection profiles with C-folds that are butt-joined also form a common abutting surface. It is conceivable that this abutting surface can optionally be designed with additional fire protection. A surge strap can be used for this purpose, for example.

Since ceilings, floors and walls of room temperature control cell systems, such as cooling cells, cannot be made in one piece due to their size, they must be manufactured using individual modular room temperature control cell elements. These are advantageously formed like a sandwich.

The room temperature cell elements can also be arranged across a corner, so that the abutting surface is arranged offset to the actual room temperature cell corner. This is particularly advantageous, since in the event of a fire, the rising gases and smoke collect on the ceiling and in its corners. A fire-protected ceiling corner can be provided by laying the abutting surface vertically and/or horizontally in relation to the ceiling downwards, for example along a wall corner element. This advantageously has at least one, advantageously two, mutually complementary fire protection profiles for fire protection. The two fire protection profiles that complement each other can be arranged overlapping each other when installed.

In a further advantageous embodiment, it is also conceivable to span the corners between abutting room wall temperature control cell element and room ceiling temperature control cell element and/or room wall temperature control cell element and room floor temperature control cell element with corner straps. Advantageously, the spanning corner strips are curved and span the two abutting edges that are arranged next to one another. This enables additional fire protection. Such overvoltage straps are used if fire protection profiles with C-folds are used.

This is of course not to be understood as limiting, so that it is also conceivable that the individual room temperature cell elements, which are butt-joined to form a flat wall surface, for example, are also additionally connected to one another with overvoltage strips. This is advantageous when fire protection profiles with C-folds are used.

In this exemplary embodiment, the spanning bands described above are not of radially curved design, but rather planar. This makes it possible for the formed abutting edges to be spanned and therefore very good fire protection can be provided. Due to the spanning straps, the abutting edge is covered and spanned. In this way, the passage of smoke and/or gas through the abutting edge along the abutting surface can be avoided. Smoke and/or gas escaping for a short period of time are kept safe in the corresponding interior space, which is spanned by the individual room temperature cell elements.

In a further advantageous embodiment, it has proven to be advantageous, both in the corner design and in the planar design, that the abutting edges to be protected are spanned by at least 10 mm. Overvoltage ranges in the range of 10-30 mm, even more advantageously 15 mm, have proven to be advantageous. Safe fire protection according to standard EN 13501-1 "Fire behavior classification of building products and building types - Part 1:
classification with the results from the tests on the fire behavior of building products".

In a further advantageous embodiment, it is conceivable for an overvoltage strip to connect an inner surface of a first room temperature cell element and an inner surface of the second room temperature cell element arranged thereon. The connection is fixed, for example riveting. In this way, even at high temperatures, ie in the event of a fire, a secure connection can be provided between the overvoltage strip and the room temperature control cell elements.

Of course, this is also not to be understood as limiting, so that it is also conceivable that the corner variant and/or the planar variant of the overvoltage strip is provided in addition to fire protection profiles that have already been embedded, in particular in the case of fire protection profiles with C-folds. As a result, additional fire safety can be ensured again.

The term “room temperature control cell element” is advantageously to be understood as meaning a component for erecting room cells which can be temperature controlled. Examples of such room cells are, for example, cold storage cells or deep-freeze cells. This is of course not to be understood as limiting, so that other room cells to be temperature-controlled are also covered by the invention, which can also be air-conditioned. It has proven to be particularly advantageous if the room temperature cell elements have at least one internal insulation layer, such as an insulation foam.

Furthermore, it is advantageous if the room temperature cell elements are of modular design. Thus, completely different sizes and geometries of the room cells, advantageously the cold storage and/or deep-freeze cells, can be formed.

In a further advantageous embodiment, the strip element can have a material thickness of 0.5 mm to 1 mm. Material thicknesses of 0.6 mm ± 0.5 mm and 0.8 mm ± 0.5 mm have proven particularly advantageous. In this case, the double layer of the first exemplary embodiment can still be formed in a sufficiently simple manner. At the same time, this double layer is stable enough so that it can be used as another Fire protection profile can reach under at least partially. In addition, sharp edges are avoided.

Finally, the present invention also relates to the use of a fire protection profile to improve the fire protection of room temperature cell elements and/or the use of a room temperature cell element to improve the fire protection of room temperature cell systems, cold rooms, cold rooms, deep-freeze cells and/or temperature-controlled rooms. In the case of the latter, rooms to be temperature-controlled are to be understood, which can usually be temperature-controlled in the temperature range from −80° C. to 100° C., such as rooms for test methods.

Furthermore, it has proven to be advantageous if the at least one inorganic fire protection element is designed as plasterboard and/or plasterboard. Furthermore, it has proven to be advantageous, in particular for weight reasons, plasterboard and / or plasterboard or similar panels. The fire protection element advantageously has a thickness of 8 to 12.5 mm ± 0.5 mm. This ensures sufficient fire protection and at the same time saves a significant amount of weight compared to thicker fire protection elements. GKFi boards have proven to be particularly advantageous as a fire protection element. An additional, advantageous impregnation of the carrier material and base material of the GKFi panels prevents the panels from "swelling" in high humidity and water ingress into the elements or damage caused by the foaming process.

Regardless of the exemplary embodiments shown here, it has proven to be advantageous to always design the respective fire protection element to be 20mm ± 5mm shorter than the thickness, also referred to as the wall thickness, of the respective one room temperature cell element. This ensures excellent positioning of the entire fire protection profile within the room temperature cell element. In addition, there is still sufficient insulation foam so that the insulation of the room temperature cell element can be ensured.

In a further advantageous embodiment it is also conceivable that the strip element directly forms the inner surface and/or the outer surface of a room temperature cell element. This is advantageous since material can be saved again as a result. In this possible exemplary embodiment, the fire protection element is then fitted in the appropriate geometry and foamed. As a result, errors and inaccuracies can be further reduced.

The condition of use is to be understood when the fire protection profile is already embedded in a room temperature cell element and this room temperature cell element is to be installed to form a room temperature cell.

The wording "essentially" means a deviation in the range of 1% to 30%, in particular from 1% to 20%, in particular 1% to 10%, in all cases used here in which this wording is used within the scope of the present invention %, in particular from 1% to 5%, in particular from 1% to 2%, of the definition that would be given without the use of this formulation.

The band elements described here are advantageously made of metal, such as aluminum, metal alloys, such as steel-based, as further examples Sheet steel, galvanized sheet steel, stainless steel, or the like.

Further advantages, features and configuration options result from the following figure description of exemplary embodiments which are not to be understood as limiting.

Detailed description of exemplary embodiments

1 shows a first embodiment of the fire protection profile 100. The embodiment shown here advantageously has a plate-like fire protection element 104 and a band element 102. Band element 102 and fire protection element 104 have a first common contact surface 106 . The shape of the band element 102 can be described via the shape path F1.

In this exemplary embodiment, the band element 102 is longer than the fire protection element 104. The band element 102 consequently protrudes beyond the free end 108 of the fire protection element 104. The overhang is advantageous in the range of 2-30% of the length of the entire fire protection element 104.

Along the further course of the shape path F1, the common contact surface 106 ends with the second end 110 of the fire protection element 104. The band element 102, on the other hand, runs further beyond the further free end 110 of the fire protection element in an unchanged, linear direction along the shape path F1.

As the shape path F1 continues, the band element 102 changes direction by essentially 180°, advantageously by 180°, so that a tongue-like area 123 results. As a result of this change in direction, the strip element 102 forms a common contact surface with itself. The band element 102 thus forms a double layer in the tongue-like area 123 . This is advantageous, since a high level of stability of the tongue-like area 123 can be achieved as a result.

As a result of this change in direction, the strip element 102 again runs in the direction of the fire protection element 104, more precisely in the direction of its second free end 110. With this second free end 110, which can also be referred to as the end face, the strip element 102 forms a second common contact surface. For this purpose, the forming path F1 runs through a further curve steeply upwards along the second free end 110 of the fire protection element 104. The band element 102 leads to a steep increase in the range of 75° to 110°, more advantageously of 100°, compared to the double layer upwards then form another curve 112. It has proven to be particularly advantageous for the stability if the further curvature 112 to the fire protection element 104 is arranged spaced apart, is advantageously formed widening to this.

For this particular geometry, it is also advantageous if the fire protection element 104 has a bevel 114 toward the second free end 110 . Particularly good stability and positioning of the fire protection profile 100 can be achieved by this bevel 114 and the curvature 112 and the resulting widening geometry between the fire protection element 104 and the strip element 102 if this is installed in room temperature control cell elements, for example.

A free space 116 is formed between bevel 114 and band element 102 . This is advantageous because it enables the fire protection profile 100 to be additionally fixed in room temperature control cell elements. For example, insulation foam (not shown) can penetrate at least partially into the free space 116 during the production of the room temperature cell elements. When the insulating foam hardens, a firm and stable arrangement of the fire protection profile 100 in the respective room temperature cell element is then made possible.

The ones in here 1 The embodiment variant of the fire protection profile 100 shown represents a possible, advantageous embodiment, but is of course not to be understood as being limited to this.

figure 2 shows a further possible embodiment of the fire protection profile 200, the widening U-shaped configuration being described here. This fire protection profile 200 also has a strip element 202 and a fire protection element 204 . Both differed in their Shape to the band element 102 and the fire protection element 104 from figure 1 .

In this embodiment, the shape path F2 is routed differently than the shape path F1 in the previous example. It is an embodiment of the fire protection profile 200, which according to the key-lock principle at abutting edges of room temperature control cell elements arranged one on top of the other with the fire protection profile 1 1 works together.

The fire protection profile 200 also has a projection of the band element 202 in relation to the first free end 208 of the fire protection element 202 .

Fire protection element 206 and band element 202 form a common contact surface 206 in the direction of shape path course F2. In this embodiment, the fire protection element 204 compared to the example in figure 1 mirrored horizontally by 180°. The bevel 214 of the second free end 210 of the fire protection element 204 is oriented downwards in this exemplary embodiment.

The band element 202 runs along the bevel 214 according to the shape path F2. The band element 202 also forms a common contact surface with the bevel 214 and thus curves upwards.

The strip element 202 is longer in the direction of the second free end 210 of the fire protection element 204 . There is an overhang. I

In the further course F2, the band element 202 follows the geometry of the free end 210 of the fire protection element 204. This means that between the end face 210 and the band element 204 again a distance is formed. Band element 202 and end face 210 are advantageously aligned essentially parallel to one another in this area of shaping path F2, advantageously running vertically.

In the further course of the shaping path F2, the band element 202 again executes a curve 212, so that the free end 222 of the band element 202 is arranged obliquely upwards. Here, too, an expanding free space 216 is provided between the free end 222 of the band element 202 and the fire protection element 204 . This free space 216 also serves to fix the exemplary embodiment 200 shown in an internally foamed room temperature control cell element, such as a cooling cell element and/or a deep-freeze cell element. The fire protection profile 200 shown here has a widening U-shaped band element 202 . In this U-shape, both legs are symmetrical to one another.

In figure 3 another possible exemplary embodiment of a fire protection profile 300 is shown. The fire protection element 304 has the same geometry as in figure 1 shown. The band element 302, on the other hand, has a further shaping path F3. The fire protection profile 300 shown here can advantageously be used for wall-ceiling joints and/or ceiling-ceiling joints.

In the example of a fire protection profile 300 shown here, the band element 302 projects beyond the fire protection element 304 at its first free end 308. The fire protection element 304 corresponds in its geometry to the fire protection element 104 in FIG figure 1 .

The band element 302 is designed as a C-bend. The band element 302 advantageously spans an angle of inclination in the range of 65° to 110°, more advantageously of 80°, in relation to the flat band element. This gradient section at least partially forms a common contact surface 306 with the end face 310 . In this exemplary embodiment 300, the fire protection element 304 is arranged as shown in FIG figure 1 . The band element 302 encloses the fire protection element 304 at a partial distance, so that it is received by the band element 302 at its second free end 310 . Only a relatively small free space 316 is formed between the band element 302 and the bevel 314 of the fire protection element 304 , which in this exemplary embodiment is completely delimited and closed off by the fire protection element 302 and the band element 304 .

figure 4 shows another exemplary embodiment of the fire protection profile 400. In this exemplary embodiment 400, the shape path F4 is designed differently than in the previous exemplary embodiments.

The fire protection profile 400 shown here is intended for arrangement on and/or in corners or, for example, to span butt edges from wall to ceiling, from wall to floor, from wall to wall or as a wall-T connection with fire protection.

The fire protection element 404 is erected in this exemplary embodiment 400, arranged at an incline to the left. This shape is due to the later installation in a room temperature cell element. By tilting the fire protection element 404, an improved fire protection seal can be achieved at abutting edges from wall to ceiling and/or from wall to floor and/or wall to wall.

The band element 402 , on the other hand, is arranged with its free end 420 initially running horizontally (forming path F4 ) in the direction of the fire protection element 404 . As the shape path F4 continues, the strip element 402 curves to the right and forms a common contact surface 406 with the fire protection element 404 . This common contact surface 406 extends to the second free end 410 of the fire protection element 404.

In the course of the shape path F4 that now follows, the band element 402 follows the course of the fire protection element 404, in particular around a first edge of the beveled free end 410. After the first edge of the second free end 410 of the fire protection element 404 has run around, the common contact surface 406 is released. The band element 402 widens in relation to the second free end 410 of the fire protection element 404 . A gap 416 is formed. Between the bevel 414 and the free end 422 of the band element 402, the free space 416 is expanded further, which space is designed to widen. The band element 402 advantageously encloses and/or spans the fire protection element 404 at least partially in its front end area 410. The band element assumes a widening U-shape.

In figure 5 Another possible exemplary embodiment 500 of a fire protection profile 500 is intended for arrangement in corners or also, for example, to securely span over butt edges from wall to ceiling and/or from wall to floor and/or from wall to wall in a fire-protected manner.

This embodiment 500 is similar to the embodiment 400 in the previous one figure 4 . The difference is that the fire protection element 504 is mirrored by 180° from the vertical is arranged. In addition, the fire protection element 504 is shown vertical and not tilted. In addition, the common contact surface 506 between the strip element 502 and the fire protection element 504 is longer than shown in FIG figure 4 the case is.

In this exemplary embodiment 500, too, the strip element 502 initially runs horizontally, starting from its first free end 520, while the fire protection element 504 is positioned vertically. In the further course of the shaping path F5, the strip element 502 is curved to the right, so that a common contact surface 506 is formed with the fire protection element 504. This common contact surface 506 extends beyond the bevel 514 and also beyond the second free end 510 of the fire protection element 504 .

In the further course of the shaping path F5, the strip element 502 runs around the free end 510 of the fire protection element 504 at a distance therefrom, advantageously at least at a distance from its end face 510. This results in the free space 516.

In the further course, the free end 522 of the strip element 502 widens further compared to the free end 510 of the fire protection element 504, so that the free space 516 is continued here as well. In this exemplary embodiment, the fire protection element 504 is positioned vertically, whereas the fire protection element 404 in 4 is positioned tilted. The fire protection profile 500 also has a widening U-shape of the strip element 502 .

In Figures 6 and 7 the band element 602 and 702 is shown as part of a fire protection profile. This serves to illustrate the different shape paths F6 and F7. Only the band elements are included for better illustration 602 ( figure 6 ) and 702 ( figure 7 ) shown. The fire protection elements are omitted for the sake of clarity.

This in figure 6 Band element 602 shown corresponds to band element 102 ( figure 1 ) and 902 ( figure 9 ). This in figure 7 Band element 702 shown corresponds to band element 1002 ( figure 10 ).

So shows figure 6 an embodiment of the band element 602. This is initially flat along the forming path F6. In the further course, a double-layered tongue 623 is formed by folding the strip element 602 by essentially 180°, advantageously completely by 180°. This double layer serves to stabilize tongue 623 for later installation in room temperature cell elements. After this double layer, the band element 602 performs two further curves, resulting in an expanding geometry. The band element 602 shown here can be regarded as a key. First, after the double layer 623 has been opened, the band element 602 assumes a pitch angle η in the range from 75° to 110°, more advantageously 100°, relative to the double layer. The band element thus runs away from the double layer. It has proven to be advantageous here if this further mold path section has a length in the range from 6.5 mm to 15 mm. This is advantageous for the subsequent arrangement of room temperature cell elements on one another, since a contact surface with a further fire protection profile is formed on this steeply rising mold path section in the range from 75° ± 5° to 110° ± 5°, more advantageously from 100° ± 5°.

Finally, the molding path to the free end of the band member 622 may traverse an additional flared curvature. This further curvature has a widening angle δ in the range from 120°±5° to 140°±5°, more advantageously from 130°±3°, in relation to the steep mold path section described above.

The strip element 602 advantageously has a material thickness of 0.5 mm to 1 mm. Material thicknesses of 0.6 mm ± 0.5 mm and 0.8 mm ± 0.5 mm have proven particularly advantageous. In this case, the double layer 623 can still be formed sufficiently simply. At the same time, this double layer 623 is stable enough to form another fire protection profile ( figure 8 ) can at least partially reach below. In addition, sharp edges are avoided.

Advantageously, the double layer has an external length of 5 ± 0.5 mm to 25 mm ± 0.5 mm, more advantageously from 7 mm ± 0.5 mm to 12 mm ± 0.5 mm, even more advantageously from 8.1 mm ± 0.5 mm to 9.1 mm ± 0. 5mm, even better from 8.6mm. An external length dimension of 8.1 mm ± 0.5 mm to 9.1 mm ± 0.5 mm, even more advantageously 8.6 mm, has proven to be advantageous, since the double layer is then sufficiently stable and the further fire protection profile, not shown here, for fire protection can sufficiently intervene. Of course, this is not to be understood as limiting, so that depending on the design, longer tongues of 10mm, 11m, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 2 3mm, 2 4mm, 25mm possible are.

So shows figure 7 another embodiment of the band element 702, which assumes an expanding U-shape. The band element 702 is initially planar along the forming path F7. In the further course, there is a curvature to the right in the direction of the forming path F7, so that the planar arrangement is eliminated. This first curvature can be understood as the first leg 736 of the U. The first leg 736 subtends an angle φ of 160° to 170° ± 5° from the previous one flat course of the band element 702 on. The adjoining base 738 is aligned essentially, advantageously completely, vertically.

With reference to the base 738, the second leg 740 then spans an angle of widening μ in the range of 120°±5°.

In addition, the lengths of the two legs 736, 740 differ from one another in this example. For sealing abutting edges, it is advantageous if the first leg 736 is longer than the second leg 740. For example, the first leg 736 can have a length in the range from 12 mm ± 5 mm to 15 mm ± 5 mm. For example, the second leg 704 can have a length in the range of 8 mm ± 5 mm to 12 mm ± 5 mm.

This embodiment variant 702 can be understood as a lock.

In figure 8 are then key 602 ( figure 6 ) and Castle 702 ( figure 7 ) merged. This occurs when two room temperature cell elements are arranged in abutting relationship (not shown). The band elements 602, 702 shown here are only shown to clarify the functional mechanism for improving fire protection.

The double-layer tongue 623 is pushed under the first leg 736 of the widening U-shape when two room temperature cell elements abut one another (not shown). This is possible because the tongue 623 is double-layered. This gripping from below can thus take place without the tongue 623 being bent.

Advantageously, when the tongue 623 is passed under the first leg 736, a force can be applied to the first leg 736, so that the latter gives way and is deflected upwards in the direction of the free end 740. Due to the restoring force of the first leg 736 that is provided at the same time, it is returned against the tongue 623 and a particularly stable connection is achieved, advantageously by means of a form fit and/or force fit, advantageously with a friction fit.

The originally open abutting edge between the room temperature cell elements (not shown) is spanned and protected against the passage of smoke and/or gas as a result of the underpassing. The fire protection properties are significantly improved when both embodiments 602, 702 are used together, according to the lock and key principle, than without using this principle.

This is largely not to be understood as limiting, so that it is also conceivable that the geometry of the first leg 736 is sufficient for the tongue 623 to be pushed underneath. A separate restoring force of the first leg is not present in this further exemplary embodiment.

Whether a restoring force of the first leg 736 can be developed depends on the fire protection element used (not shown).

For example, in embodiment 200 ( figure 2 ) between bevel 214 fire protection element 204 and band element 202 no free space formed. A common contact area is shown. Consequently, the first leg 236, which forms the common contact surface with the bevel 214, cannot be separately deflected again e.g. by applying pressure when the tongue-like section is pushed underneath (not shown in figure 2 ).

In Figure 9 and Figure 10 further embodiments of the fire protection profiles 900 and 1000 are shown. Band element 902 corresponds to band element 102/602 ( figures 1 and 6 ). Band element 1002 corresponds to band element 702 ( figure 7 ) Therefore, the explanations for these two band elements on the above figures 1 , 6 and 7 referred.

In addition, is now in figure 9 the fire protection element 904 is also shown. It can be seen that the fire protection element 904 shown has a significantly more pronounced bevel 914 than the fire protection element 104 in FIG figure 1 shows. At the same time, the longer bevel 914 causes a reduction in the area of the end face 910.

In this advantageous further embodiment 900, the strip element 902 and the fire protection element 904 form a first common contact surface 906. The shape of the band element 902 can be defined via the shape path F9, which follows the shape path F7 in figure 7 and Formfpad F1 in figure 1 corresponds to be described.

In this exemplary embodiment 900, the band element 902 is longer than the fire protection element 904. The band element 902 consequently protrudes beyond the free end 908 of the fire protection element 904. The overhang in the range of 2-30% of the length of the entire fire protection element 904 is advantageous.

Along the further shaping path F9, the common contact surface 906 ends with the second end 910 of the Fire protection element 904. The strip element 902, on the other hand, runs further beyond the end face 910 of the fire protection element 904. The end face represents the other free end 910 of the fire protection element 904.

As the shape path F9 continues, the band element 902 changes direction by 180°, resulting in a tongue-like area 923 in which the band element 902 forms a common contact surface with itself. The band element 902 forms a double layer. The double layer advantageously has an external length of 5 to 10 mm ± 0.5 mm, more advantageously of 8.1 mm ± 0.5 mm to 9.1 mm ± 0.5 mm, even more advantageously of 8.6 mm. An external length dimension of 8.1 mm ± 0.5 mm to 9.1 mm ± 0.5 mm, even more advantageously 8.6 mm, has proven to be advantageous since the double layer is then sufficiently stable and the further fire protection profile, not shown here, for fire protection can sufficiently intervene.

As a result of this change in direction of the shaping path F9, the band element 902 again runs in the direction of the fire protection element 904, more precisely in the direction of the second free end 910. The band element 2 forms a second common contact surface 925 with this further free end 910.

As the shape path F9 continues, the strip element 902 rises steeply in an obliquely inclined upward direction, in order then to form a further curvature 912 . It has proven to be particularly advantageous for the stability if the further curvature 912 is arranged at a distance from the fire protection element 904 and is advantageously designed to widen to this.

For this particular geometry, it is also advantageous if the fire protection element 904 has a bevel 914 toward the second free end 910 of the fire protection element 904 . Particularly good stability and positioning of the fire protection profile 900 can be achieved by this bevel 914 and the curvature 912 and the resulting widening geometry between the fire protection element 904 and the band element 902 if this is installed in room temperature control cell elements, for example. Regarding the angle of incline and the angle of flattening, on figure 6 referred. The values given there are applicable to this embodiment.

The ones in here figure 9 The embodiment variant of the fire protection profile 900 shown represents a possible, advantageous embodiment, but is of course not to be understood as being limited to this.

figure 10 shows an embodiment of a fire protection profile 1000 with the shape path F10, which the shape path F7 of figure 7 is equivalent to. Regarding the values is therefore on figure 7 referred. The values are on here in figure 10 embodiment shown applicable.

In this embodiment, the shape path F10 is routed differently than in the previous example figure 9 . It is an embodiment of the fire protection profile 1000, which according to the key-lock principle at abutting edges of room temperature cell elements arranged one on top of the other with the fire protection profile 900 figure 9 works together.

Here, too, the strip element 1002 projects beyond the first free end 1008 of the fire protection element 1004 .

A common contact surface 1006 then follows in the further shape path course F10. The fire protection element 1004 has a double, symmetrical bevel 1014 . This is the difference to the fire protection element 204 figure 2 . The fire protection element 1004 shown here has a different geometry. Here, too, a common contact surface 1006 between the strip element 2 and the fire protection element 4 is first formed. This common contact surface 1006 ends with the start of the bevel 1014 towards the free end 1010 of the fire protection element 1004. A free space 1013 is therefore formed between the band element 1002, more precisely between its first leg 1036, and the bevel 1014.

In the further course of the shaping path F10, a second contact surface 1025 is then formed between the strip element 1002 and the end face 1010, ie the free end 1010 of the fire protection element 1004.

In the further course of the shaping path F10, towards the free end 1022 of the band element 1002, its widening occurs in relation to the bevel 1014. The free space 1016 is formed.

In the further course, the band element 2 again performs a curvature 1012, so that the free end 1022 of the band element 1002 is arranged obliquely upwards. A widening free space 1016 is formed here between the free end 1022 of the band element 1002 and the fire protection element 1004 .

In Figure 11 and Figure 12 are further advantageous embodiments of fire protection profiles 1100 and 1200 shown, which are used for fire protection of room corners. The fire protection profiles 1100 and 1200 shown here can therefore be referred to as room corner fire protection profiles. These are further alternatives to those already in Figure 4 and Figure 5 described fire protection profiles 400 and 500.

In figure 11 the fire protection element 1004 is off 10 shown. Since a room corner fire protection profile 1100 is provided here, the shape path F11 is designed significantly differently than the shape path F10 in figure 10 .

The first free end 1120 of the band element 1102 is free-standing. The shape path F11 starts at the first free end 1120 perpendicular to the fire protection element 1004 and runs towards it. In order to avoid angular predetermined breaking points of the strip element 1102, the shape path F11 follows an elongated right-hand curve in order to then form a significantly reduced common contact surface 1106 with the fire protection element 1004. In the further course of the shaping path F11 in the direction of the second free end 1122, the free space 1113 is first formed, in the connection of which the strip element 1102 and the end face 1110 of the fire protection element 1004 form a common contact surface 1125. Following this, the common contact surface 1125 is released, so that a U-shaped widening is formed. Again, free spaces 1113 and 1116 are formed.

In figure 12 the same fire protection element 1004 is shown, with the band element 1202 describing a different shape path F12. The free end 1220 is free-standing. The shape path F12 starts at the first free end 1220 perpendicular to the fire protection element 1004 and runs towards it.

In order to avoid angular predetermined breaking points of the strip element 1202, the shape path F12 follows an elongated right-hand curve in order to then form a common contact surface 1206 with the fire protection element 1004.

In the further course of the shaping path F12 in the direction of the second free end 1222, first the free space 1213 is formed, in the connection of which the strip element 1202 and the end face 1210 of the fire protection element 1004 form a common contact surface 1225. Following this, the common contact surface 1225 is released, so that a U-shaped widening is formed. The strip element 1202 again forms free spaces 1213 and 1216 with the fire protection element 1004 .

figure 13 shows a further embodiment of a fire protection profile 1300. This embodiment is advantageously used, for example, in the arrangement of room ceiling temperature control cell elements (not shown here) on one another or in transitions from room wall temperature control cell element to room ceiling temperature control cell element. These room temperature cell elements are arranged in abutting relationship. The fire protection profile 1300 shown here is designed as a C-fold.

In the example of a fire protection profile 1300 shown here, the first free end 1320 of the strip element 1302 projects beyond the fire protection element 1304 at its first free end 1308.

The common contact surface 1306 is formed as the shaping path F13 continues. The band element 1302 encloses the fire protection element 1304 in its further form path course F13, so that it is separated from the band element 1302 its second free end 1310 is added. Relative to the common contact surface 1306, the strip element 1302 spans a pitch angle in the range from 65°±5° to 110°±5°, more advantageously from 80°±5°. This gradient section at least partially forms a common contact surface with the end face 1310 . As the shape path F13 continues, the band element 1302 curves again, so that it is aligned essentially parallel to the common contact surface 1306 . The free end 1322 terminates before the bevel 1314.

The in the Figures 1 to 5 and Figures 9 to 10 as well as figure 13 The fire protection profiles 100, 200, 300, 400, 500, 900, 1000 and 1300 described and their parts are provided for surface formation, so that wall surfaces, ceiling surfaces and/or floor surfaces can be formed by arranging several room wall temperature control cell elements, room ceiling temperature control cell elements or room floor temperature control cell elements on one another. If a room cell is to be formed, for example a cold room and/or a deep-freeze cell, then individual room temperature control cell elements are modularly combined with one another and connected to one another. This takes place in that the room wall temperature control cell elements are arranged so that they abut one another via their abutment surfaces. The abutting edges must be given special protection in terms of fire protection, since gas and/or smoke can penetrate through the abutting edges or abutting surfaces of two room wall temperature control cell elements arranged next to one another. This leads to the spread of fire and must be prevented. With the different exemplary embodiments of the fire protection profiles disclosed here, as well as the individual band elements and/or fire protection elements, abutting edges can therefore be spanned across the surface and/or across corners and designed to be fire-protected.

figure 14 shows two room temperature cell elements 24, 26, which are spaced apart from each other. In this example, the two room temperature cell elements 24, 26 are designed as wall elements.

Both room temperature cell elements 24, 26 are constructed in the manner of a sandwich and each have an inner surface 28 and an outer surface 30. FIG. The space between the two surfaces 28, 30 is foamed with insulating foam 32, for example PUR foam or PIR foam. This is advantageously carried out with room temperature cell elements which are combined to form cold storage cells and/or deep-freeze cells.

The inner surface 28 is that surface which faces the interior of the room cell to be produced. The outer surface 30 is that surface which faces the outside of the room cell to be produced.

Insulation foam 32 is known to the person skilled in the art from the prior art, for example for the production of cold storage cells and/or deep-freeze cells. The insulation foam 32 is also shown here for better illustration.

The first room temperature cell element 24 has two fire protection profiles 1000 . These have already been figure 10 described in detail. Here they are shown embedded in the room temperature cell element 24 . It can be seen that the two fire protection profiles 1000 are arranged on the abutment surface 34 . The respective band elements 1002 advantageously form at least part of the surface of the abutment surface 34 . Furthermore, the abutment surface 34 is designed as a depression in this example.

The second room temperature cell element 26 is arranged opposite the room temperature cell element 24 . This room temperature cell element 26 is also constructed in the manner of a sandwich and has an inner surface 28 and an outer surface 30 . The intermediate space is filled with insulating material 32 . The room temperature cell element 26 has two fire protection profiles 900 which are embedded on the inner surface 28 and the outer surface 30 . It is also conceivable that the band element 902 forms the inner surface 28 and/or the outer surface 30 directly.

It is shown that here only the tongue-like projection 923 is arranged protruding from the abutment surface 36 of the room temperature cell element 26 . The rest of the room surface fire protection profile 900 is embedded in the room temperature cell element 26 . The embedded fire protection profiles 900 and 1000 shown are firmly positioned by the insulating foam 32 .

Furthermore, the abutment surface 36 has an elevation which is designed to fit the depression of the abutment surface 34 with a precise fit. This coupling of the two abutment surfaces 34, 36 increases the resulting abutment surface (not shown). This has a positive effect on fire protection. A possible passage of gas and/or smoke along the impact surface (not shown) towards the outer surface 30 is slowed down.

The fire protection elements 904, 1004 used here advantageously have a length L of 15 cm±1 cm perpendicular to the respective end face 34, 36. In direction H, to be understood here as width perpendicular to the plane of the paper, the fire protection profiles 900 and 1000 extend along the entire inner surface 28 and outer surface 30 and also along the abutting edges. So when assembling the two room temperature cell element 24, 26 whose abutting edges are limited on both sides with fire protection profiles 900 and 1000. It is possible for the fire protection elements 904, 1004 to have a width H of up to 3000 mm±5 mm. Consequently, room temperature cell elements can be formed which can have a width H of 3000mm±5mm. In this way, easily walkable room cells can also be created.

In figure 15 is a section of the fire protection element 1004 of the room temperature cell element 24 with fire protection profile 1000 figure 14 shown without ribbon element 1002. The symmetrical bevel 1014 can be clearly seen here. The bevel angles α=18° or α=30° are selected for a particularly good seal and adjustment when installed. Depending on the bevel angle, the bevel 1014 is also lengthened or shortened. If the bevel angle α=18° is chosen, AN, as an imaginary adjacent leg, assumes the value 12 mm ± 1 mm. If the angle of bevel α=30° is selected, AN, as an imaginary adjacent leg, assumes the value 18mm ± 1mm. The bevel 1014 is then steeper and longer than with a bevel angle of α=18°.

In figure 16 12 is a section of a fire protection element 900 of the room temperature cell element 26 figure 14 shown. It can be seen that only a simple, elongated bevel 914 is provided here. A wedge shape of the fire protection element 904 results. The bevel angle is selected with β=30° or with β=18°. Depending on the bevel angle, the bevel 914 is also lengthened or shortened. If the bevel angle β=30° is selected, AF, as an imaginary adjacent side, assumes the value 18 mm ± 1 mm. If the bevel angle β=18° is selected, AF, as an imaginary adjacent leg, assumes the value 12mm ± 1mm. The bevel 914 is then flatter and shorter than in a Bevel angle of β=30°. The bevel angle is formed depending on the later use.

In figure 17 then the formation of the abutment surface S is shown in that the two room temperature cell elements 24, 26 are arranged in abutment against one another via the two abutment surfaces 34, 36. In order to be able to form the resulting abutting surface S in a fire-protected manner, the tongue-like projection 923 reaches under the first leg 1036 of the opposite fire-protection profile 1000 and slides under it. In this way, a form fit, more advantageously a friction fit, can be produced. By sliding underneath, a force can optionally be applied to the first leg 1036 . The arm 1036 is deflected from its original position into the free space 1013 by the application of force. At the same time, there is also a restoring force, so that the inner and outer abutting edges SI, SA are sealed particularly well by the overlapping of the tongue-like section 923 and the first leg 1036 . As a result, the abutting edges SI, SA are additionally sealed and designed with improved fire protection.

In figure 18 A possible embodiment of part of a room temperature cell system 50 is shown. The embodiment shown here shows an arrangement of two room temperature cell elements 26, 38, which form a side wall corner. A total of four fire protection profiles 900, 900, 1000, 1000 are arranged here, with the room tempering cell element 26 together with fire protection profiles 900 at least partially arranged therein forming the structure figure 13 is equivalent to. The fire protection elements 904 used have a length L of 150mm ± 10mm. The fire protection element 1004 has a length L, which is formed depending on the thickness of the additional room temperature cell element 38 . The The length L of the fire protection element 1004 is designed to be 20mm±5mm shorter than the thickness D of the room temperature cell element.

In the example shown here, a corner is formed so that the corner butt edge is fire-resistant. A further room temperature cell element 38 is provided for this purpose. This has a fire protection profile 1000 (from Fig 10 ) on. A fire protection profile 1100 (from 11 ) provided on the inner surface 28. Due to the special shape path F11 (not shown here), the impact corner can be spanned and provided with fire protection. The fire protection element 1104 of the fire protection profile 1100 is advantageously 60mm±1mm long. This is more than sufficient to ensure fire protection. The strip element transitions into the second room temperature cell element 38 and thus spans the rounded corners.

In addition, it should be pointed out that, in general and not limited to this exemplary embodiment, the room temperature cell element 38 can be any room temperature cell element. For example, it can be designed as a room wall temperature control cell element and/or a room ceiling temperature control cell element and/or a room floor temperature control cell element. All of these various embodiments are disclosed with the general room cell element 38 herein.

For the sake of simplicity, the insulating foam is not shown in the room temperature cell elements 26, 38 shown here.

In figure 19 is another embodiment of a part of a room temperature cell system 51 is shown, which a Represents wall-to-ceiling closure. The room temperature control cell element 26 forms an abutting surface S here with a room ceiling temperature control cell element 40 . To improve fire protection, three fire protection profiles 1300 with a C-fold with fire protection elements 904 of different lengths and a single fire protection element 904a with a flat strip element 1302a are arranged here. However, this in turn shows another, new form path. The strip element 1302a is only straight and thus ends directly in the room temperature cell element 26. It forms a common contact surface with the strip element 1302 of the fire protection profile 1300 arranged directly adjacent thereto.

All fire protection elements 904, 904a used here have a wedge shape. The wedge-shaped fire protection element 904a covers the inner abutting edge SI of the corner with the strip element 1302a and is embedded in it parallel to the room ceiling temperature control cell element 40 . The contact surface formed in this way to the fire protection profile 1300 of the room temperature cell element 26 and fire protection element 904a arranged underneath it strengthens the inside corner and the abutting edge SI and significantly improves fire protection.

The fire protection elements 904 in the room temperature cell element 26, which represents a wall element, and the fire protection element 904a have a length L of 150 mm ± 1 mm. The fire protection element 904b of the ceiling temperature control cell element 40, on the other hand, is shortened because of the thickness of the ceiling. It has a length L of 60mm ± 1mm. The fire protection element 904b is advantageously designed to be 20mm±5mm shorter than the thickness of the room ceiling temperature control cell element 40. The total thickness of the room ceiling temperature control cell element 40 is therefore 80mm±5mm in this example.

For the sake of simplicity, the insulating foam is not shown in the room temperature cell elements 26, 40 shown here.

The exemplary embodiment shown here is not to be understood as being limited to the fire protection profiles 1300 . It is entirely possible to replace all of the fire protection profiles 1300 shown here with the fire protection profiles 900 and 1000 according to the lock and key principle, as already described above. In this way, overlapping areas can then be formed on the abutting edges SI, SA.

An additional improvement in fire protection can be provided by the room temperature cell system 52 . This is in figure 20 shown. The room temperature control cell system essentially corresponds to 52 from FIG figure 20 the room temperature cell system 51 figure 19 , so that the reference numbers remain the same.

The room temperature control cell element 26 forms an abutting surface S here with a room ceiling temperature control cell element 40 . To improve fire protection, three fire protection profiles 1300 with C-folds with fire protection elements 904 of different lengths and a single fire protection element 904a with band element 1302a are arranged here. The two fire protection elements 904 in the room temperature cell element 26, which represents a wall element, and the fire protection element 904b have a length L of 150±10 mm. The fire protection element 904b of the ceiling temperature control cell element 40, on the other hand, is shortened because of the thickness of the ceiling. It has a length L of 60mm ± 1mm. The fire protection element 904b is advantageously designed to be 20mm ± 5mm shorter than the thickness of the Room ceiling temperature control cell element 40. The overall thickness of the room ceiling temperature control cell element 40 in this example is 80 mm ± 5 mm.

In this exemplary embodiment, a wedge-shaped fire protection element 904a is also arranged in the room ceiling tempering cell element 40, which is delimited by a straight, that is to say not bent, band element 1302. The wedge-shaped fire protection element 904a covers the inner abutting edge SI of the corner with the strip element 1302a and is embedded in it parallel to the room ceiling temperature control cell element 40 . The contact surface formed in this way to the fire protection profile 1300 of the room temperature cell element 26 and fire protection element 904a arranged underneath it strengthens the inside corner and the abutting edge SI and significantly improves fire protection. For the sake of simplicity, the insulating foam is not shown in the room temperature cell elements 26, 40 shown here.

In addition, an over-tensioning strip 44 is now also arranged in the inner corner area. This over-tension band 44 again covers the inner abutting edge SI from the inner surface. The overtensioning strap 44 is advantageously fastened to the respective inner surface 28 with fastening means 46 . The fastening means 46 are advantageously designed as rivets. Furthermore, it has proven to be advantageous if the spanning strip 44 spans the inner corner hem SI by at least 15 mm ± 1 mm. As a result, fire protection can be further improved. The inside corner butt edge SI is additionally sealed against gas and smoke by the overvoltage strip 44 . This can further improve fire protection and in particular standard EN 13501-1 "Fire behavior classification of building products and building types - Part 1: Classification with the Results from the tests on the fire behavior of building products" are met.

For the sake of simplicity, the insulating foam is not shown in the room temperature cell elements 26, 40 shown here.

A further overtensioning strap 45 is arranged on the opposite outer surface 30 . It spans the outer abutting edge SA of the room temperature cell element 26 and the room ceiling temperature cell element 40 and thus also the two fire protection profiles 1300. Here the span strip 45 is flat. It advantageously spans the outer abutting edge SA by at least 15mm ± 1mm.

In figure 21 Another embodiment of part of a room temperature cell system 53 is shown. The connection between room temperature control cell element 26 and room floor temperature control cell element 42 is shown here as an example. The room floor temperature control cell element 42 is also designed to be particularly reinforced. Three fire protection profiles 900 are shown on the abutting edges between room floor temperature cell element 42 and room temperature cell element 26 . These have fire protection elements of different lengths. The fire protection elements 904 have a length L of 150 mm ± 1 mm and the fire protection element 904b has a length L of 60 mm ± 1 mm. Here, too, fire protection profiles with C-bend 1300 are used.

The exemplary embodiment shown here is not to be understood as being limited to the fire protection profiles 1300 . It is quite possible to replace all fire protection profiles 1300 shown here with fire protection profiles 900 and 1000 according to the key-lock principle, to be replaced as described above. In this way, overlapping areas can then be formed on the abutting edges SI, SA.

For the sake of simplicity, the insulating foam is not shown in the room temperature cell elements 26, 42 shown here.

In figure 22 Another embodiment of a portion of a room temperature cell system 54 is shown. The connection between room temperature control cell element 26 and room floor temperature control cell element 42 is shown here as an example figure 21 shown.

In addition, an overvoltage strip 44 is now also arranged in the corner area. This spanning band 44 again covers the inner corner butt edge SI from the inner surface. The overtensioning strap 44 is advantageously fastened to the respective inner surface 28 with fastening means 46 . The fastening means 46 are advantageously designed as rivets. The span band spans the inner corner joint area SI by at least 15mm ± 1mm. As a result, fire protection can be further improved and, in particular, comply with standard EN 13501-1 "Fire behavior classification of building products and building types - Part 1: Classification using the results of fire behavior tests for building products".

A further overtensioning strap 45 is arranged on the opposite outer surface 30 . It spans the outer abutting edge SA of room temperature cell element 26 and ceiling temperature cell element 40. Here it is Surge strap 45 just formed. The spanning strap 45 spans the outer abutting edge by at least 15mm ± 1mm.

In figure 23 Another exemplary embodiment of part of a room temperature control cell system 55 is shown, with two room ceiling temperature control cell elements 40 abutting here. Here, too, each of the two room ceiling tempering cell elements 40 has two fire protection profiles 1300 each. After all fire protection profiles 1300 are of the same design in the exemplary embodiment 55 shown here, they all also have a fire protection element 904 in each case. This is 150mm ± 10mm long.

For the sake of simplicity, the insulation foam is not shown in the room ceiling temperature control cell elements 40 shown here. The exemplary embodiment shown here is not to be understood as being limited to the fire protection profiles 1300 . It is entirely possible to replace all fire protection profiles 1300 shown here with fire protection profiles 900 and 1000, as already described above. In this way, overlapping areas can then be formed on the abutting edges SI, SA.

In figure 24 Another exemplary embodiment of a part of a room temperature control cell system 56 is shown, with two room ceiling temperature control cell elements 40 being made up here figure 23 collide.

In addition, an overvoltage strip 45 is now also arranged over the inner abutting edge SI. This over-tension band 45 again covers the inner abutting edge SI from the inner surface. The overtensioning strap 45 is advantageously fastened to the respective inner surface 28 with fastening means 46 . The fastening means 46 are advantageous as rivets trained. Here the overvoltage band 45 is flat. It advantageously spans the inside edge SI by at least 15 mm ± 1 mm.

A further overtensioning strap 45 is arranged on the opposite outer surface 30 . It spans the outer abutting edge SA of room ceiling temperature control cell element 40 and room ceiling temperature control cell element 40. Here the spanning band 45 is flat. It advantageously spans the inside edge SI by at least 15 mm ± 1 mm. As a result, fire protection can be further improved and, in particular, comply with standard EN 13501-1 "Fire behavior classification of building products and building types - Part 1: Classification using the results of fire behavior tests for building products".

figure 25 FIG. 12 further shows an exemplary embodiment of part of a room temperature cell system 57. Here, a composition of a room floor temperature cell element 42 with a room temperature cell element 26, advantageously a wall element, is shown. Two fire protection profiles 1300 are positioned opposite one another with mirror symmetry on the outer surface 30 . Room floor temperature cell element 42 with a shortened fire protection element 904b and room temperature cell element 26 with fire protection element 904 are placed in abutment with one another.

Furthermore, the room temperature cell element 26 also has a fire protection profile 1300 with a fire protection element 904 on the opposite inner surface 28 . The fire protection elements 904 have a length L of 150 mm ± 10 mm. The fire protection element 904b has a length L of 80mm±5mm.

In addition, another fire protection profile 1100 is arranged on the inner surface 28 in the lower corner area. Its band element 1102 spans the corner joint, so that additional protection against the room floor temperature control cell element 42 can be formed here. The fire protection element 1104 has a length L of 60mm±5mm. Of course, the fire protection profile 1200 can also be used here instead of the fire protection profile 1100 12 be used.

The exemplary embodiment shown here is not to be understood as being limited to the fire protection profiles 1300 . It is entirely possible to replace all of the fire protection profiles 1300 shown here with the fire protection profiles 900 and 1000 according to the lock and key principle, as already described above. In this way, overlapping areas can then be formed on the abutting edges SI, SA.

For the sake of simplicity, the insulation foam is not shown in the room ceiling temperature control cell elements shown here.

figure 26 FIG. 12 further shows an exemplary embodiment of part of a room temperature cell system 58. Here, a room floor temperature cell element 42 is combined with a room temperature cell element 26, advantageously a wall element figure 25 shown.

For the sake of simplicity, the insulation foam is not shown in the room ceiling temperature control cell elements 26, 42 shown here.

In addition, an overvoltage strip 44 is now also arranged in the corner area. This overvoltage band 44 covers the inner edge SI again from the inner surface. The overtensioning strap 44 is advantageously fastened to the respective inner surface 28 with fastening means 46 . The fastening means 46 are advantageously designed as rivets. In this example, the inner corner butt edge SI is designed to be at least 15 mm 11 mm spanned by the overlay strip.

A further overtensioning strap 45 is arranged on the opposite outer surface 30 . It spans the outer abutting edge SA of the room temperature cell element 26 and the room floor temperature cell element 42. Here the span band 45 is flat. The outer abutting edge is designed to be spanned by the overtensioning strip 45 by at least 15 mm±1 mm. As a result, fire protection can be further improved and, in particular, comply with standard EN 13501-1 "Fire behavior classification of building products and building types - Part 1: Classification using the results of fire behavior tests for building products".

Finally shows 27 a more complex part of a room temperature cell system 59 with several room temperature cell elements 38 and the use of the fire protection profiles 900, 1000 and 1100. For the sake of simplicity, the insulating foam is not shown in the room temperature cell elements 38 shown here. In this example, a total of three room temperature cell elements 38 are arranged in abutting relationship. This can be, for example, two ceiling elements and one wall element or two wall elements and a wall corner element. It is shown that different room temperature control cell elements 38 are protected against fire by the overlapping areas of the strip elements according to the key-lock principle according to the EN 13501-1 standard "Fire classification of building products and building elements - Part 1: Classification using the results from tests on the fire behavior of building products" can be installed in order to provide modular room temperature cell systems.

Although the invention has been illustrated and described in more detail by the advantageous exemplary embodiments, the invention is not restricted by the disclosed examples. Other variations can be derived from this by a person skilled in the art without departing from the scope of protection of the invention. In particular, the invention is not limited to the combinations of features specified below, but other combinations and sub-combinations that are obviously executable for a person skilled in the art can also be formed from the disclosed features.
