Description

The invention relates to a smoke or fire protection device according to the preamble of claim 1.

Such smoke or fire protection devices are known and serve to prevent or inhibit the spread of fire and / or smoke in buildings usually in buildings. There is a desire to be able to produce the widest possible such smoke or fire protection devices, since they can then be integrated into the building in a particularly inconspicuous manner.

In the case of wide smoke or fire protection devices, there is the problem that the winding shaft bends, which leads to tensions in the protective element during unwinding. It is therefore out of the DE 196 10 532 A1 known to store the roll lying on rolls. The rollers are fixed relative to the housing so that they rotate when the winding is rotated and the flexible protective element unwinds or winds up. This has the advantage that the winding is supported in its full longitudinal extent of the rollers, so that the winding shaft must be stored only at their sides and yet no excessive deflection of the winding shaft is to get. A disadvantage of this solution is that it is relatively expensive.

From the DE 196 10 532 A1 It is known to store the protective element on a sliding surface, which should have the smallest possible friction. In order to minimize the friction, a bearing on rollers is proposed, which leads to a relatively rapid wear of the protective element. Alternatively, an air cushion bearing is addressed. This is very complex in terms of design.

The invention has for its object to provide a smoke or fire protection device in which the protective element is better protected against wear.

The invention solves the problem by a smoke or fire protection device having the features of claim 1.

It is advantageous that the fire protection textile is little stressed during winding and unwinding.

It is a further advantage that is tightened by the moderate friction of the protective element on the support surface of the winding. Wrinkles are avoided in the wrap.

In the context of the present description, a fire protection element is understood to be a fire protection textile, that is to say an object constructed from fibers, for example a fabric or a scrim, which consists of a non-combustible, fire-retardant material. For example, the fire protection textile comprises glass fibers and / or metal fibers and / or wires.

The fire protection element can also be constructed in one, two or more layers. In particular, it is advantageous if the fire protection element is laminated on at least one of its outer sides with metal foil, in particular aluminum foil.

Under the winding shaft is in particular an at least partially understood prismatic component on which the flexible protective element is added. In general, the winding shaft extends over at least 90% of the width of the protective element, usually it has at least the same width as the protective element.

It is possible, but not necessary, that the winding shaft consists of partial winding shafts, which are torsionally rigid and / or detachable, in particular form-fitting, connected to each other. Since the winding shaft does not have to meet a particularly high requirement in terms of flexural strength due to the horizontal storage on the recording, it is possible to build them from part winding shafts and assemble, for example, only at the mounting shaft of these partial winding shafts. This allows a particularly efficient installation.

Under the feature that the receptacle has a support surface on which the reel is mounted resting, is understood in particular that the support surface, in particular to a fastening device with which the smoke or fire protection device is attached to a building, is rotatably mounted. Although smaller pivoting movements are quite tolerable, it is favorable when the receptacle is fixed, for example, mounted relative to a housing or to a winding shaft bearing.

Under the feature that the winding is mounted lying flat on the support surface, is understood in particular that the winding in a contact surface has contact with the support surface. The contact surface is the area of the bearing surface that touches the fire protection element. The contact surface extends along a longitudinal axis of the winding shaft.

It is advantageous, but not necessary, for the contact surface to be interruption-free with respect to its longitudinal extent along the longitudinal axis. Thus, it is possible that the winding does not rest completely on the support surface with respect to a height along the longitudinal axis. It is particularly favorable when the receptacle is designed such that the winding has at least along a contact length contact with the bearing surface, which corresponds to at least 0.9 times the width of the protective element. The contact length is the sum of all distances, which results from vertical projection of the contact surface on the longitudinal axis. So a high smoke-tightness is achieved, that is, that hardly any smoke can pass between the winding and recording.

It is advantageous if the receptacle is designed so that the protective element slides on the bearing surface when the winding is wound or unwound. At least when the flexible protective element is in its bearing arrangement, the receptacle at least predominantly absorbs the weight of the coil. It is not possible but necessary that the winding shaft is mounted at one or both ends in a, in particular vertically displaceable, fixed bearing. It is also possible that the winding shaft rests on the receptacle and the receptacle completely absorbs the weight of the winding shaft.

Preferably, the smoke or fire protection device comprises a winding shaft motor, which is arranged for example in the winding shaft, and with which a torque can be applied to the winding shaft. Alternatively or additionally, an engine arranged outside the winding shaft can be used. This is particularly advantageous when large torques are to be applied.

It is possible that this winding shaft motor is supported via a torque armature on a fastening device, wherein the smoke or fire protection device can be fastened by means of the fastening device to a building element. The torque armature can be firmly connected to the fastening device, but this is not necessary. Thus, it can be provided that the torque armature is caught relative to the fastening device, so it can not move completely free, but the torque armature is loose relative to the fastening device.

It is particularly favorable if the winding shaft and / or the flexible protective element have a width of at least 6 meters. With such a width, it is particularly advantageous to be able to dispense with storage on rollers.

Preferably, the receptacle is trough-shaped. This means, in particular, that the receptacle seen from the winding is concave.

The flexible protective element is constructed from a first segment and at least one second segment, wherein the first segment and the at least one second segment are sewn together in at least one seam and wherein the receptacle comprises a friction protection device which is arranged such that the at least one seam is protected against abrasion when the flexible protective element is brought from its bearing assembly in its protective arrangement. It is an advantage that the smoke or fire protection device can very often be operated for test purposes without the seam becoming worn. If the protective element is made up of three or more segments, then more than one seam exists and the friction protection device is arranged in such a way that all seams are protected against abrasion when the flexible protective element is brought from its bearing arrangement into its protective arrangement.

For example, over 10000 opening and closing operations can be achieved by a friction protection device in the form of a teflon strip applied to the receptacle, without the smoke or fire protection device excessively wearing out.

According to a preferred embodiment, the receptacle has a friction protection surface made of friction protection material, which has a Reibschutzmaterial hardness of at most 80 HV10. With such a low hardness of the wear due to the sliding of the protective element on the support surface is largely predominantly on the friction surface, so that the flexible protective element is spared at this point. The friction protection surface may extend over the predominant part of the receptacle with respect to the longitudinal extent of the receptacle. That is not necessary.

According to a preferred embodiment it can be provided that the friction protection surface is formed on a friction protection element which is mounted interchangeable. Worn anti-friction elements can then be replaced quickly.

The friction protection surface is preferably made of organic material, in particular of plastic. In other words, the friction protection surface is formed on a friction protection element, which is constructed of organic material. The plastic is in particular a polymer. The organic material preferably has a Mohs hardness of at most 4. For example, the organic material is polytetrafluoroethylene or another, at least partially halogenated, plastic. Alternatively or at least in sections, the friction protection surface may be a smooth metal surface, in particular a polished metal surface.

The flexible protective element is constructed from a first segment and at least one second segment, wherein the first segment and the at least one second segment at least also by means of suture, wherein the suture has a suture hardness and wherein the suture hardness is preferably greater than a suture hardness of the suture. If the flexible protective element made of at least two segments, it can be very easy to manufacture. In particular, it is possible within the scope of a method according to the invention to sew the segments together on site. This saves the transport of large-scale fire protection elements, which is expensive.

Because the suture hardness is greater than the sabot hardness, the suture wears, but not the suture, as the suture slides over the suture during wrapping and / or unwinding.

The above relationship to hardness can be determined by rubbing the suture against the friction-protecting material or the friction-protecting device, in particular the friction-protecting surface. If the suture scores the friction protection material or the friction protection device, in particular the friction protection surface, the suture hardness is greater than the friction material hardness. The friction protection surface is preferably arranged such that the seam slides at least predominantly over the friction protection surface when the flexible protection element is brought from its bearing arrangement into its protective arrangement. This is to be understood in particular as meaning that at least one imaginary point exists on the seam, which covers a longer path over the friction protection surface than over any other part of the support surface which is not friction-protected.

According to a preferred embodiment, the friction protection material is selected such that a sliding friction coefficient for the sliding friction between the seam and the friction protection surface is at most 0.25, in particular at most 0.2.

The receptacle has a sliding surface of sliding material having a sliding material hardness, wherein the sliding material hardness is greater than the Reibschutzmaterial hardness. For example, the sliding surface is made of steel. In particular, the sliding material hardness is at least 10 HV10 greater than the Reibschutzmaterial hardness, in particular by at least 50 HV10. This is particularly advantageous in this case when the protective element, as provided in a preferred embodiment, has a seam-free region, wherein the seam-free region at least predominantly slides over the sliding surface when the planar protective element is brought from its bearing arrangement and its protective arrangement. In other words, the sliding surface and the friction protection surface are arranged to each other so that only the seam and possibly adjacent areas run over the Reibschutzfläche when the protective element is brought by its bearing assembly in its protective arrangement, but not the seamless areas.

Preferably, the Gleitmaterial hardness is at least 100 HV10. According to a preferred embodiment, the sliding material is selected such that a sliding friction coefficient for the sliding friction between the seam and the sliding surface is at most 0.35, in particular at most 0.3.

In particular, the suture, the friction-resistant material and the sliding material are selected so that the friction-resistant material can be scored by the suture and that the sliding material can not be scored by the suture. In other words, the Mohs hardness of the suture is greater than the Mohs hardness of the friction material and the Mohs hardness of the slip material is greater than that of the suture. The suture may comprise multiple components, such as glass fibers and metal wires or strands.

The above relationship to hardness can be determined by rubbing the suture against the sliding material or sliding surface. If the suture does not scratch the sliding material or sliding surface, the suture hardness is less than the sliding material hardness.

According to one embodiment, the friction protection device comprises a spacer device, which is connected to the flexible protective element and extends along the seam, so that a bearing force acting on the seam is reduced. In other words, the spacer device is configured to at least predominantly receive the support force and the seam adjacent to the spacer does not contact the support surface or drive only a smaller support force from the support surface compared to the state where the spacer device is absent is.

Preferably, the spacer device comprises two strands which are connected to the flexible protective element and run along the seam so as to enclose the seam therebetween. In this way, the seam is particularly effectively protected.

According to a preferred embodiment, the friction protection material and the sliding material are selected so that the suture material and / or the protective element on the friction protection material at least five times higher friction than on the sliding material. In other words, the friction coefficient of the sliding friction between suture and / or the protective element on the one hand and the On the other hand sliding material on the other hand, at least five times the coefficient of friction sliding friction between suture and / or the protective element on the one hand and the friction protection material on the other. This maintains the firming effect of friction on the bearing surface while protecting the seam.

According to a preferred embodiment, the friction protection material and the sliding material are selected so that the suture material and / or the protective element on the friction protection material shows at least five times higher wear than on the sliding material. In other words, abrasion in milligrams for the suture per meter of rubbing length between the suture, on the one hand, and the antislip material is at most one fifth of the abrasion, as the suture slides against the slip material instead.

Preferably, the smoke or fire protection device comprises a fastening device, which are designed to initiate a weight of the protective element from the receptacle into a building part in the mounted state of the smoke or fire protection device, wherein the fastening device comprises a plurality of support elements which are spaced from each other by an average distance spaced apart, the average distance is at most 1 meter. This has the advantage that the winding shaft is stored safely even if the recording yields in case of fire. Due to the small distance of the support elements results in a uniform force in case of fire, which is not always achieved in known systems. As a result, the protective element is always smoke-tight on the receptacle even in the event of fire and it can also result from different deformation of the winding shaft on the one hand and the recording on the other hand no gap.

1 shows a smoke or fire protection device according to the invention 10 to close an in 1 not marked opening. The smoke or fire protection device 10 has a flexible protective element 12 in the form of a fire protection textile, which is composed of a first segment 14.1 and a second segment 14.2, which are sewn together.

The smoke or fire protection device 10 also has a winding shaft 16 on which the flexible protection element 12 is wound up. The winding shaft 16 and the protective elements 12 form a wrap 18 , The winding shaft 16 is by means of a drive device 20 , in the present case in the form of a winding shaft motor 20 , automatically driven. By actuating the drive device 20 is the protective element 12 from the winding shaft 16 Unwindable and windable on this.

The smoke or fire protection device 10 includes a recording 22 , which is formed trough-shaped. The wrap 18 lies on a support surface A the recording 22 on, giving the weight of the coil 18 is absorbed by the receptacle 22.

2 shows the smoke or fire protection device 10 in a cross section. It can be seen that the winding 18 on the support surface A the recording 22 rests. 2 also shows that the smoke or fire protection device 10 a housing 24 includes and with a fastening device 26 containing a plurality of support elements 27 on a part of the building 28 , attached in the present case to a wall. From the support elements 27 is in 2 only the support element 27.1 shown. Further support elements 27.2, 27.3, ... are in 3 located. It can be seen that the support elements 27 a distance d have each other. It is possible, but not necessary, for the support elements 27 are arranged equidistantly. An average distance in the form of the arithmetic mean is preferably at most one meter. Decreases the strength of the support elements in case of fire 27 , so it is still the protective element 12 kept safe.

At the free end of the protective element 12 is how in 2 shown a finishing bar 30 attached, flush with the housing 24 completes when the protective element 12 in its bearing arrangement. Is the protective element 12 in its protective arrangement, so sits the end strip 30 in the present case on the ground 32 on, leaving an opening 34 in the building part 28 is closed. 2 shows a state between bearing assembly and protection arrangement.

2 shows that the drive device 20 a torque armature 36 includes, in the housing 24 is loosely received, but can not move completely freely. Should the protective element 12 are wound, so the drive device 20 subjected to electric current, so that a torque between the winding shaft 16 and torque anchors 36 forms. This pivots the torque armature 36 until he touches the case 24 strikes and the torque in the housing 24 initiates. The protective element 12 is then wound up. Alternatively, the drive device 20 also, as shown in dashed lines, by means of a swivel arm 38 on the housing 24 or on the fastening device 26 be attached by means of a joint.

1 shows that the two segments 14.1, 14.2 by a seam 40 connected to each other. These are the two segments 14 (Reference signs without counting suffix denote the object as such) by suture material 42 , which in the present case consists of metal and plastic threads, sewn together.

3 shows in the lower part of a plan view of the recording 22 , It can be seen that the recording 22 a friction protection device 44 in the form of friction protection surfaces 44.1, 44.2, 44.3, which are formed on the friction protection elements 46.1, 46.2, 46.3. The friction protection elements 46 are formed by strips of polytetrafluoroethylene which rest on a steel tray 48 are glued on. Between the individual friction protection elements 46 , For example, between the friction protection element 46.1 and the friction protection element 46.2 are sliding surfaces 50 , in the example, the sliding surface 50.1. The sliding surfaces 50 are through the surfaces of the steel tub 48 educated. A sliding material hardness H ₅₀ the steel of the steel tub 48 in the present case is approximately 150 HV 10 , A friction material hardness H ₄₄ is less than Shore D50.

3 shows in the upper part of the picture that the protective element 12 in the places where the segments 14 , In the present case, the four segments 14.1, 14.2, 14.3 and 14.4, are sewn together, seams 40.1, 40.2, 40.3 exist. The wrap 18 has in the places of the seams 40 a slightly larger diameter. As indicated by the vertical dashed lines, the friction protection elements are 46 in the area of seams 40 arranged so that the seams 40 on the friction protection surfaces 44 slide when the protective element 12 wound on the winding shaft 16 or unwound from it.

Between the seams 40 There are seamless areas 52.1, 52.2, which when winding or unwinding on the sliding surfaces 50 slide. This will ensure that the seams 40 through the friction protection elements 46 are protected, while avoiding excessive wear, that the seamless areas 52 not over the friction protection elements 46 slide. However, it can also be provided that the friction protection element 46 over the full width of the winding shaft 16 extends so that the protective element 12 at least over a predominant width over the friction protection elements 46 expires.

3 schematically shows that the winding shaft 16 is screwed together from a first part winding shaft 54.1 and a second part winding shaft 54.2. In order to prevent unintentional disassembly, both partial winding shafts 54.1, 54.2 are connected to each other in the screwing point by welding points, by bolts or by adhesive elements.

The suture 42 for the seams 40 is a thread that includes stainless steel wires as well as plastic fibers. A friction coefficient ρ _42.44 for the sliding friction between the friction material and the friction protection surface 44 is about 0.15, a coefficient of friction ρ _42.50 between the suture 42 and the sliding surface 50 is about 0.25.

4 shows a further embodiment of a smoke or fire protection device according to the invention 10 in which the friction protection device 44 over the seams 40 extending friction protection layers comprises. Thus, the seam 40.1 with the friction protection layer 44a covered, the seam 40.2 with the friction protection layer 44b , The friction protection layers 44a . 44b may be, for example, plastic films with the fire protection element 12 are connected, for example glued, welded or sewn. The friction protection layers 44a are strip-shaped and run over the respective seam.

5 shows a view according to the section CC, so that the dashed seam 40.2 and the protective friction protection layer 44b can be seen.

6 shows a wrap 18 a smoke or fire protection device according to the invention 10 in which the friction protection device 44 a first spacer device 58.1 and a second spacer device 58.2, which are each formed as a strand. The spacer devices 58.1 and 58.2 are flexible and project with one end over the seams 40 out.

The spacer devices 58 are also on the support surface A on and run so close to the respective seam 40 in that they do not make contact with the bearing surface A or so that only a small impact force F _camp on the respective seam 40 acts. In 6 is the support force F _camp drawn for the spacer device 58.1. The support force F _camp acts in the example shown only on the spacer device 58 but not on the seams 40 ,

7 shows an embodiment in which the friction protection device 44 a spacer device 58 that is, for each seam 40 comprises two strands, between which the seam is arranged. So has the spacer device 58 the strands 60.1, 60.2, which run along the seam 40.1 and have a small distance from this, so that the bearing force F _camp distributed on the two strands 60.1, 60.2 and the seam 40.1 no support force F _camp experiences. Along the seam 40.2 run the strands 60.3 and 60.4. Instead of the term of the support force F _camp could also be the bearing pressure used to emphasize that it is a force acting on a surface.

7 also shows that the protective element 12 along a contact length KL Contact with the bearing surface A Has. The contact length KL preferably carries at least 0.9 times a total width B of the roll 18 , where in 7 the width B _{14 is} given, which is the width B a segment 14 designated. The ratio between contact length KL and width B corresponds to the in 7 shown ratio between the contact length KL for a segment 14 of the roll 18 and the width B _{14 of} this corresponding segment.
