Description

The invention relates to a guide rail for lateral guidance of a flexible smoke and / or fire protection curtain, which separates only in case of fire areas of a building to prevent smoke and / or fire propagation.

From the DE 10 2010 005 455 A1 is a smoke and / or fire protection and a smoke and / or fire protection with such a smoke and / or fire protection curtain known. Such smoke and / or fire protection hangings are parts of flexible smoke aprons or aprons that can be installed within a building to achieve certain protection goals. Such protection goals include, for example, prevention of fire damage from fumes, facilitation of fire fighting, some shielding of escape routes or escape routes to keep them low smoke, creating smoke sections, preventing ignition of unburned gases, or reducing component thermal stress. Such protection goals can be achieved by smoke curtains and fire aprons, which are used as needed as a curtain to separate space areas.

From the DE 10 2010 005 455 A1 It is known that such smoke and / or fire protection aprons have a flexible curtain which can be wound onto a winding shaft. The winding shaft can be provided with a drive. At rest, the flexible curtain is completely wound on the winding shaft. The flexible curtain consists eg of thin, flexible, temperature-resistant fabric and is characterized by a small bale diameter when wound up. As a result, the wound on the winding shaft flexible curtain can be made very compact and takes up little space within a ceiling area or the like. Like in the DE 10 2010 005 455 A1 described, the curtain can for example be formed from a textile support and be provided with intumescent material that foams and / or cools in case of fire. The intumescent material may for example be incorporated in pockets of the wearer.

Another such curtain and fire curtain is from the EP 2 110 506 A1 known. It is also described that the curtain can be guided laterally on a rope within guide rails, not shown here.

Such guide rails for such hangings are for example in the WO 2008/154906 A1 or the WO 02/053679 A1 shown. Nothing is said about the material of the guide rails; the guide rails are shown only as a U-profile guide strips, which are placed on a wall surrounding a wall to be closed.

From the US 4,398,585 A , of the EP 1 029 557 A1 , of the EP 0 065 876 A as well as the DE 103 25 237 A1 and the EP 1 669 110 A2 Smoke and / or fire barriers with smoke and / or fire curtains are known, with different measures are proposed for sealing against smoke passage.

In particular, at the EP 1 669 110 A2 proposed a guide rail in which a guide gap is formed like an arrow to form a labyrinth seal. In this case, a projection on a boundary wall of the guide gap engages in a recess on the other wall of the guide gap, so that the smoke and / or fire protection curtain rests sealingly on bearing surfaces. The disadvantage here is that the production of the guide rail on the one hand is complicated and on the other hand is disadvantageous in terms of possible wear and possible jamming.

Particularly preferred embodiments of the guide rail are characterized in that the guide rail is formed from a steel sheet. Preferably, a steel guide rail is provided, which is characterized by one-piece construction.

Preferably, a metal sheet is profiled and welded together.

Preferably, an opening arrow-like labyrinth is located in a catchment area.

Preferably, the labyrinth is formed such that the flanks of the arrow are not parallel.

Preferably, the guide gap forming a labyrinth is designed in such a way that a three-point support for the smoke and / or fire protection curtain is formed in the case of an opening of the metal profile caused by heating.

In contrast to the embodiment of the EP 1 669 110 A2 is merely a three-point pad, ie provided a linear support for the curtain. This causes a reduced friction. As a result, the fire curtain is smoother and thus easier to close.

Next causes a corresponding linear support compared to a surface support a much lower wear.

Preferably, an arrow-like guide gap is provided whose flanks are not parallel.

The geometry of the guide gap is preferably selected such that in every possible situation - with air pressure or without air pressure - when heated or cold - a safe three-point support or two-point support is possible, which provides the desired tightness in fire / smoke curtains.

Preferably, the labyrinth is formed such that opposite flanks of the flash are not parallel to one another.

Preferably, the curtain spans more and pushes harder on all contact points of the labyrinth of the guide rail, the greater the pressure that arises in a fire.

The geometry of the guide gap is preferably selected such that in any situation - with air pressure or without air pressure - when heated or cold - a secure four-point support or three-point support is possible, which provides the desired tightness in fire / smoke curtains.

Because of a four-point support or three-point support in the preferred second embodiment of the smoke and / or fire protection closure provided here, a much lower wear than in the case of the prior art provided surface support and even more tightness than the first embodiment allows.

The geometry of the guide gap has been selected significantly depending on the thickness of the blind. In a preferred case, the strength of the hanging z. B. 1 mm (2 mm - overlapping). The selected geometry can guarantee a secure fit of the fabric at all linear contact points of the guide rail with every thickness of the curtain.

The rope or steel cable preferably comprises a steel cable or an aramid cord with a temperature limit of up to 500 ° C. or a silicate cord with a temperature limit of up to 1300 ° C.

Preferred is a combination of a welt made of an exciting rope, e.g. a steel rope, provided with an arrow labyrinth or a lightning-shaped Labyrith. By combining the tensioning of the curtain by means of the rope and the arrow labyrinth or the lightning-shaped labyrinth only a line-like support is achieved, which causes less wear. As a result, on the one hand lower demands on the materials with regard to the wear to make, which allows a more cost-effective production.

It is also essential that several thousand opening and closing cycles without wear-related failure are possible.

Such smoke and / or fire barriers are subject to constant quality checks, where a proper function is checked. Furthermore, continuous tests are to be completed for such smoke and / or fire protection shutters, where it can be shown that the curtain withstands ten thousand cycles without failure.

With regard to the standards for endurance tests, reference is made to EN 14600, EN 1191 and additionally to PrEN 16034.

A particular advantage with regard to cost-effective production results from the simple production of the guide rail by multiple profiling of a one-piece metal sheet. This is preferably formed with a first tubular inner profile area.

The inner profile region preferably encloses a closed chamber. This inner chamber is accessible only through the insertion or guide gap. The guide gap is bounded by a first and a second profile wall region, which are each formed like an arrow, preferably in such a way that the flanks of the arrow profile are not parallel in the first and in the second profile wall region.

These profile wall regions connect the inner profile region with a likewise preferably tubular outer profile region. The outer profile region is preferably completely guided around the inner profile region. The edges of the metal sheet are preferably brought together on the opposite side of the guide gap and welded together there. Thus, the guide rail is double-walled with an inner chamber and a surrounding, almost annular chamber formed. The guide rail is integrally formed from a metal sheet.

The double wall has several advantages. On the one hand, a very stable guide rail is thereby obtained even with thin metal sheets, in particular in connection with the tube shape and the profilings. On the other hand, the chamber design is advantageous in terms of Luftabschlusses and with respect to the smoke-tightness.

In particular, in conjunction with the sealing measures by the clamping device and the purely linear support can be a very reliable, durable smoke and / or fire protection produce very cost.

In Fig. 1 a smoke and / or fire protection closure is shown in horizontal section, wherein only a lateral region of the smoke and / or fire protection closure 10 is shown.

The smoke and / or fire protection closure 10 has a smoke and / or fire protection curtain 12 and a guide device 14 for this purpose.

The smoke and / or fire curtain 12 is formed, for example, as a smoke skirt or smoke curtain to separate in case of fire different areas of a building, in particular a building, such that a passage of smoke is prevented from one area to another. Such a smoke curtain extends for example from a roof underside or ceiling underside up to a certain height above the floor and limited roof or ceiling section surfaces. In normal operation, ie in non-fire, the smoke curtain is usually invisible or hidden. For example, it is wound on a winding shaft, not shown here, as is well known in the art. In the event of fire, the smoke protection curtain is extended, in particular lowered, so that different areas of the building are separated. For example, the smoke curtain extends in case of fire up to a certain height above the floor, so that a downwardly open and upwards of the Building ceiling gives limited space. Smoke is caught in it and a lateral outflow of smoke and the hot combustion gases into another smoke section is counteracted.

The smoke and / or fire curtain 12 may alternatively or additionally be designed as a fire curtain or fire curtain. As is usually the case with the smoke protection curtain, the fire protection curtain is concealed in the normal position and is extended in case of fire. In the embodiment as a fire curtain, the smoke and / or fire curtain 12 has a defined fire resistance, thus preventing the spread of fire over a certain time.

A possible more precise construction of the smoke and / or fire protection curtain 12 is described in the prior art explained in the introduction and will not be explained further here.

At the in Fig. 1 1, a lateral edge 16 of the smoke and / or fire protection curtain 12, which is guided in a lateral guide rail 18 of the guide device 14, is provided with a piping 20, in which a cable 22, in particular a wire rope, is accommodated.

The rope 22 is stretched to train, so that a tensioning device 24 is provided, by means of which the lateral edges 16 away from each other, so in the direction of the middle of the smoke and / or fire curtain 12 is stretched away.

The guide device 14 has on each side of the smoke and / or fire protection closure 10 each have a guide rail 18, of which only one is shown in the figures. The guide rail 18 on the other side results from a mirror image of the guide rails 18 shown here.

Identical guide rails 18 can be used on the left and right, each rotated by 180 ° relative to one another.

The guide rail 18 has a metal profile 26 which is integrally formed from a single metal sheet 28.

In a preferred embodiment, the metal sheet 28 is a steel sheet, by appropriate multiple profiling in the in the Fig. 1 to 3 is shown bent shape.

As is clear from the Fig. 2 to 3 results, the metal profile 26 has an inner profile region 30 and an outer profile region 32.

The inner profile region 30 and the outer profile region 32 are tubular, in particular rectangular tubular, formed. The inner profile region 30 is seen in cross section round except for an insertion 34 which forms a guide gap 36 for the edge 16 of the smoke and / or fire curtain 12, closed, so that an inner chamber 38 is formed, in which the guide gap 36 opens, the but otherwise closed all around. At the upper and lower end of the metal profile 26, the inner chamber 38 is open for insertion of the edge 16 of the smoke and / or fire curtain. Thus, the inner chamber 38 is surrounded by a tubular shape up to the guide gap 36.

Also, the outer profile region 32 is substantially tubular and encloses an inner space 40, in which the inner profile region 30 is inserted.

Thus, the outer walls of the outer profile area 32 are guided all the way around the inner profile area 30 except for the guide gap 36.

On the guide gap 36 opposite side, the edges of the metal sheet 28 abut each other and are here materially connected to each other. In particular, the metal sheet edges 42 are welded together by means of a weld 44.

The inner profile region 30 and the outer profile region 32 are connected to one another by a first connecting wall region 46 and a second connecting wall region 48, wherein between the first connecting wall region 46 and the second connecting wall portion 48 of the guide gap 36 is formed.

As a result, an intermediate chamber 50 is formed by the tubular inner profile region, the connecting wall regions 46, 48 and the outer profile region 32, which - is enclosed on all sides - except for the ends of the metal profile 26.

The first connecting wall portion 46 has a recess 52 recessed into the intermediate chamber 50 from the center of the guide gap. The second connecting wall region 48 has a projection 54 projecting toward the middle of the guide gap 36. In particular, the guide gap 36 is seen in cross-section approximately arrow-like or arrow-shaped and thus forms a labyrinth 56th

In particular, the guide gap 36 is seen from the inner chamber 38 outwardly with increasing gap width.

In particular, the first connecting wall region 46 has a first bending edge 58 in the transition between the outer profile region 32 and the first connecting wall region 46, a second bending edge 60 in the transition region between the inner profile region 30 and the first connecting wall region 46 and an intermediate bend 62. The angles measured in the intermediate chamber 50 at the first bend edge 58 and the second bend edge 60 are each less than 90 °. For example, the angles are about 85 ° to 50 °, and most preferably 70 °.

The second connecting wall region 48 has a third bending edge 64 in transition to the outer profile region 32, a fourth bending edge 66 in the transition to the inner profile region 30 and an intermediate bend 68 forming the tip of the projection 54.

The angles measured in the intermediate chamber 50 at the third bend edge 64 and the fourth bend edge 66 are greater than 90 °.

Preferably, the angles at the Umbiegungskanten 64, 66 are formed differently. Preferably, the angle at the fourth bend edge 66 at the transition to the inner chamber 38 is smaller than the angle at the third bend edge 64, which is located at the transition to the outer profile region 32.

As a result, the flanks 70 of the arrow-like guide gap 36 are not parallel to each other.

The guide gap 36 is preferably narrower at the inner end opening into the inner chamber 38 than at the projection 54 and at the end open to the outside in the region of the outer profile region 32.

In the region of the projection 54, the guide gap 36 is wider, e.g. 0.5 mm to 3 mm wider than the edge 16 of the smoke and / or fire curtain 12th

A vertical plane spanned by the first bend edge 58 and the second bend edge 60 is not touched by the tip of the projection 68, or at most just touched. In Fig. 3 an example is shown where this plane is formed by the central longitudinal plane through the metal profile 26, wherein the tip of the projection 68 just does not extend to this center plane.

As in Fig. 1 shown, the tensioned by the tensioning device 14 touched smoke and / or fire curtain 12 only one or both of Umbiegungskanten 58, 60 and the tip of the projection 68, so that a two-point support or a three-point support is achieved.

As in Fig. 3 5, on the rear side opposite to the guide gap 36, a fastener 72 for mounting the guide rail is provided, which has a plurality of fastener through holes 74 (not shown) such as screws or the like.

In the Fig. 4 to Fig. 6 shown second embodiment of the guide rail 14 differs from the above-mentioned first embodiment of the guide rail 14 only in the embodiment of the guide gap 36th

In addition to a first bending edge 158 in the transition between the outer profile region 32 and the first connecting wall region 46, a second bending edge 160 in the transition region between the inner profile region 30 and the first connecting wall region 46 and the first central bend 162, the first connecting wall region 46 has the tip of a second projection 153 forming third middle bend 163.

Thus, the angle measured in the intermediate chamber 50 at the second bend edge 160 remains smaller than 90 ° as in the first embodiment. However, the angle measured at the first bending edge 158 in the intermediate chamber 50 is greater than 90 ° here. Most preferred is an angle at the second bend edge 160 of 70 ° and an angle at the first bend edge 158 of 105 °.

Correspondingly, in addition to a third bend edge 164 in transition to the outer profile region 32, a fourth bend edge 166 in transition to the inner profile region 30 and the second middle bend 168 forming the tip of a first projection 154, the second connection wall region 48 has a fourth central bend 169.

Thus, the measured in the intermediate chamber 50 angle at a fourth Umbiegungskante 166 remains greater than 90 °. However, the angle measured at the bending edge 164 measured in an intermediate chamber 190 is less than 90 ° here. Most preferred is an angle at the third bending edge 164 of 70 ° and an angle at the fourth bending edge 166 of 105 °.

In contrast to the first embodiment, this results in six flanks 176, 178, 180, 182, 184, 186 of the guide gap 36, which are formed such that respective opposite flanks are not parallel to one another. As a result, the guide gap 36 is not arrow-shaped, but designed in a flash shape to form an even more effective labyrinth seal.

The first flank 176 is formed between the second bend edge 160 and the first center bend 162 and is not parallel to the fourth flank 182 formed between the fourth bend edge 166 and the second middle bend 168.

The second flank 178 is formed between the first middle bend 162 and the third middle bend 163 and is not parallel to the fifth flank 84 formed between the second middle bend 168 and the fourth middle bend 169.

The third edge 180 is formed between the third middle bend 163 and the first bend edge 158 and is not parallel to the sixth edge 186 formed between the fourth middle bend 169 and the third bend edge 164.
