Definitions

the invention relates to a fire or smoke protection device according to the preamble of claim 1 and a building with such a fire or smoke protection device.
Such fire or smoke protection devices serve to close a building opening in case of fire so that for a given time a fire on one side of the building opening can not spread to the other side.
Such fire or smoke protection devices can also be smoke aprons, which hinder the spread of smoke.
To be able to close particularly wide building openings or to hinder the spread of smoke on a broad front, correspondingly wide fire or smoke protection devices are necessary. In case of fire, there may be heat-related distortions that make the sealing effect of the fire or smoke protection device in question.
the GB 735,201 describes a fire or smoke protection device with two spatially separated end elements, which are driven by a shaft. For locking the winding shafts locking devices are provided laterally. Also, this system does not solve the problem of heat-related distortion.
the invention has for its object to improve the security against fire in fire or smoke protection devices.
the invention solves the problem by a fire or smoke protection device having the features of claim 1 and a building therewith.
An advantage of such a fire or smoke protection device is that the anchor device holds the winding shaft even if, for example, the fastening device has totally deformed due to heat from a fire.
the anchor device may have a plurality of anchor elements, which each interact individually with the winding shaft form fit and prevent the winding shaft deformed by more than a tolerable degree. It is then even tolerable that the fastening device is largely completely deformed and the winding shaft is held exclusively by the anchor device. This makes it possible to build the fastening device of low temperature resistant material, which reduces the space.
the fire or smoke protection device is understood in particular to mean any device which is designed to significantly delay or prevent the propagation of a fire or smoke in its protective arrangement.
the fire or smoke protection device is a fire protection device and designed to resist fire for at least 30 minutes.
the specifications for fire or smoke protection devices are given for example in the DIN.
the fire or smoke protection device in particular meets the requirements of DIN EN 1634-1 or DIN EN 12101-1.
the fire or smoke protection device may for example be a roll protection gate, a fire protection closure, a fire protection curtain or a smoke skirt.
the bearing arrangement is understood in particular to mean that arrangement in which the partitioning element is present rolled up.
the fire or smoke protection device then occupies a small space.
the fire or smoke protection device is normally in the bearing assembly, in case of fire in the protection arrangement.
the protective arrangement can also be called a closure arrangement.
a flexible partitioning element that is fire retardant and flexible.
a flexible partitioning element that is to say a bendable partitioning element, does not necessarily have to be elastic.
the foreclosure element may comprise a plurality of segments connected to one another in an articulated manner Roll curtain form, the final element thus formed while flexible, but usually not elastic.
winding shaft Under the winding shaft is understood in particular a rotatably mounted about its longitudinal axis structure which is designed so that the foreclosure element is wound on it. It is possible, but not necessary, for the winding shaft to be completely cylindrical. For example, it may be sufficient if the winding shaft has cylindrical sections, so that the partitioning element can be wound up.
the fastening device is understood in particular to mean any device by means of which a gravity acting on the winding shaft can be introduced into the building. It is possible, but not necessary, that the fastening device is designed as a housing which at least partially surrounds the winding shaft.
the anchor device is understood in particular to mean a device which prevents the winding shaft from falling down when a bearing device is destroyed, the bearing device being a device by means of which the winding shaft is mounted. It is possible, but not necessary, for the anchor device to always receive a proportion of the weight. Thus, it is possible that the anchoring device is designed so that it only receives a significant proportion of, for example, more than 20% of the weight of the winding shaft and / or partition element when the bearing device fails by means of which the winding shaft is mounted in normal operation. In other words, the anchoring device can be designed such that it absorbs at least part of the weight of the winding shaft and the partitioning element when and only if the bearing device of the winding shaft has been so damaged by a fire that it gives way. By so yielding, the winding shaft moves down until it is prevented from further downward movement by the anchor device.
the anchoring device it is possible, but not necessary, for the anchoring device to be fitted with the fastening device connected is. It is also possible that the anchor device is designed for direct connection to the building part, on which the building opening is formed. However, the fire or smoke protection device is particularly simple in construction, when the anchor device is attached to the fastening device.
the winding shaft has a width of at least 10 meters.
the invention is also advantageous for less long winding shafts, the advantages of the invention are particularly evident in longer winding shafts.
the anchor device is designed to introduce a weight force at least of the winding shaft in the form of a tensile force.
the anchoring device is designed in particular such that the winding shaft hangs on it, in particular if the bearing device of the winding shaft no longer supports or holds it. That is, the anchor device does not carry the winding shaft, but it holds them if necessary.
the winding shaft is at least partially cylindrical and has a cylinder jacket surface, wherein the winding shaft has at least one winding shaft recess on the cylinder jacket surface and wherein the anchor device has at least one anchor element which is designed to engage in the winding shaft recess.
This intervention can be a purely passive process that is intrinsically safe. As soon as the partition element is unwound sufficiently far from the winding shaft, the anchor element engages in the winding shaft recess and thus forms a positive connection. It is possible, but not necessary, for the anchor element to pivot into the winding shaft recess.
the at least one winding shaft recess is arranged so that it is at least partially hidden by the partition element when the partition element is in the bearing assembly and is uncovered by the partitioning element when the partitioning element is in the protective arrangement.
the anchor element can not engage in the winding shaft recess as long as the partition element is not in the protective arrangement.
the anchoring element engages in the winding shaft recess, which can be a purely passive process, which is therefore intrinsically safe.
the partitioning element has a partition element recess which is formed so that the at least one anchor element engages through the partition element recess in the winding shaft recess, in particular pivots when the partition element is in the protective arrangement.
the region of the partitioning element adjacent to the partitioning element recess carries the weighting force of the partitioning element, so that the partitioning element can be fastened behind the winding shaft recess with respect to an unwinding direction of rotation of the winding shaft. This increases the stability of the attachment of the partitioning element to the winding shaft.
the partitioning element preferably has a plurality of partition element recesses and / or winding shaft recesses which are spaced along a longitudinal axis of the winding shaft, wherein the anchoring device has a plurality of anchor elements which are designed to engage in one of the winding shaft recesses.
the plurality of anchor elements increases the likelihood that a sufficiently large number of anchor elements engage the recesses, which reduces the probability of failure.
the fire or smoke protection device has a bearing device, by means of, in particular, on which the winding shaft is rotatably mounted.
the winding shaft can lie on the bearing device.
the storage device then absorbs only pressure forces.
Such a storage device is particularly easy to produce.
the disadvantage of such a storage device namely the sensitivity to thermal distortion and the concomitant risk that the fire or smoke protection device or pinion shaft does not securely close the building opening in case of fire is eliminated by the presence of the anchor device. This results in a simultaneously easy to manufacture and to install and safe fire or smoke protection device.
At least a plurality of the anchor elements has a head, with which the respective anchor element has contact with the partition element, and a web, to which the head is fastened, wherein the at least one winding shaft recess has a first section with a first clear cross section and a second portion having a second clear cross section, wherein the first clear cross section is greater than a head width of the head so that the head engages the winding shaft recess when the head reaches the winding shaft recess and wherein the second clear cross section smaller than the head width, so that the head is catchable in the winding shaft recess.
the first section is usually located in front of the second section.
the head therefore first slips through the first section and then enters the second section, which he can not leave again.
the clear cross section of the winding shaft recess decreases monotonically during the transition from the first section to the second section.
the head comprises a sliding element, in particular a roller, by means of which the head slides along the partition element, in particular rolls, when the partition element is unwound from the winding shaft.
At least one anchor element is biased toward the winding shaft.
the fire or smoke protection device is a roller door and the Abschottelement comprises a slatted curtain of mutually hingedly connected slat elements.
the anchoring device comprises a fishing hook, which, when the Abschottungside is not in the protective arrangement, out of engagement with the winding shaft, and which, when the Abschottungselement is in its protective arrangement, with the winding shaft thereby positively cooperates, that the Fanghaken the winding shaft at least partially engages.
According to the invention is also a building with a building opening on which a fire or smoke protection device according to the invention is arranged.
FIG. 1 shows in its subfigure 1a a fire or smoke protection device 10 according to the invention for closing a building opening 12 of a schematically drawn building part 14, with a flexible partition element 16, in the present case in the form of a fire protection textile, a winding shaft 18 and a fastening device 20, by means of the fire - or smoke protection device 10 is attached to a mounting side B on the building part 14.
the fire or smoke protection device 10 also has an anchor device 22, which comprises an anchor element 23.1, which is articulated in a base point 24.1 on the fastening device 20 and with a head 26.1 in an in FIG. 1 a non-visible winding shaft recess engages.
the head 26.1 is connected via a web 28.1 to the foot 24.1.
FIG. 1a shows the foreclosure element 16 in its protective arrangement in which it closes the building opening 12.
the partition element 16 is fastened to the winding shaft 18 along a fastening line 30, which runs perpendicular to the plane of the paper, for example, screwed or glued.
the fire or smoke protection device 10 comprises a bearing device 32 which has a first bearing roller 34.1 and a second bearing roller 34.2.
On the bearing rollers 34 (reference numeral without Zählsuffix denote the object as such) is the winding shaft 16, optionally mounted with at least partially wound foreclosure member 16.
the bearing device 32 is part of the fastening device 20 in the present case.
FIG. 1b shows the winding shaft 18 in a plan view. It can be seen that the winding shaft 18 is cylindrical and has a cylinder jacket surface 36. In the cylinder jacket surface 36, a first winding shaft recess 38.1 and a second winding shaft recess 38.2 are formed.
the winding shaft recesses each have a first portion 40, which has a first clear cross section Q1, and a second portion 42 with a second clear cross section Q2, the is separated from the first section 40 by a transition section 44. In the transition section 44, the clear cross-section decreases monotonously.
FIG. 1b also shows the head 26.1 of the anchor element 23.1. It can be seen that a head width K of the head 26 is smaller than the first clear cross section Q1 and larger than the second clear cross section Q2. If the winding shaft 18 is therefore rotated at a unwinding rotational speed ⁇ , the head 26.1 engages in the first section 40 and engages behind the winding shaft 18 in the second section 42 of the winding shaft recess 38.1.
FIG. 1b also shows a second anchor element 23.2 with a head 26.2, which engages in the same manner in the second winding shaft recess 38.2.
Figure 1c shows a mounting bracket 46 of the anchor device.
the attachment bracket has a base plate 48 to which the first anchor element 23.1 and the second anchor element 23.2 are articulated in their respective base points 24.1, 24.2 and connected by means of a shaft 25.
Figure 1d shows the anchor element 23.1. It can be seen that it by means of a spring 50 against the winding shaft 18 (see. FIG. 1a ) is biased.
Figure 1e shows a plan view of the winding shaft 18, which has a longitudinal axis L.
the partitioning element 16 has a first partitioning element recess 45.1, which is designed such that the one anchor element 23.1 passes through the partitioning element recess 45.1 into the winding shaft recess 38.1 when the partitioning element is shown in FIG. 1e in the protection arrangement.
the partitioning element recess 45.1 and the winding shaft recess 38.1 lie one above the other so that the head 26.1 engages through both recesses 38.1, 45.1.
the partitioning element 16 also has a second partition element recess 45.2, which is aligned with the winding shaft recess 38.2.
the winding shaft 18 may also have further, not shown here Abschottungselement-recesses, in particular for each winding shaft recess exactly one.
Subfigure 1f shows a view of the situation in subfigure 1e from the side. Upon further rotation of the winding shaft 18 of the head 26.1 comes into engagement with the recess 38.1.
FIG. 1g shows the situation in which the partitioning element 16 is not in the protective arrangement and the winding shaft recess 38.1 is covered by the partitioning element 16.
the head 26.1 can not engage in the winding shaft recess 38.1.
FIG. 2 shows the fire or smoke protection device 10 in two states, namely once in the protection arrangement (solid lines) and once in the bearing assembly (dash-dot-dot line). It can be seen that the anchor element 23.1 rests with its head 26.1 on the wound-up partition element 16 when it is in the bearing arrangement. If the partitioning element 16 is unwound from the winding shaft 18, the head 26.1 slides on the partitioning element 16 and moves downwards. At the in FIG. 2 shown fire or smoke protection device, the winding shaft 18 moves toward the building part 14.
the anchor element 23.1 ' (reference symbols with apostrophe designate the respective object in its position when the partitioning element is in its bearing arrangement) engages in the in FIG. 2 non-visible winding shaft recess 38, so that the head 26.1 'positive fit cooperates with the winding shaft recess and prevents further unwinding.
FIG. 3 shows a further embodiment of a mounting bracket 46 for a fire or smoke protection device according to the invention, in which the anchor member 23 has a nose 52 at its head 26, with the threading into the winding shaft recess 38 is facilitated.
FIG. 4 shows in his FIG. 4a the fire or smoke protection device 10 with the partition element 16 in the bearing assembly. It can be seen that the head 26.1 rests on top of the winding winding shaft 18 and end element 16. If the partitioning element 16 is unwound at the unwinding speed ⁇ , in this case counterclockwise, the head 26.1 slides on the partitioning element 16, which conceals the winding shaft recess 38, so that the head 26.1 can not engage.
FIG. 4b shows the case that foreclosure 16 is in its protective arrangement and in the present case rests with a cover strip 53 on the floor.
the head 26.1 has engaged in the second section 42 of the winding shaft recess 38.
the head 26.1 is spaced in this position by a small amount from an inner surface of the winding shaft 18.
the anchor device 22 then already cooperates with the winding shaft 18 in a form-fitting manner, the winding shaft 18 does not exert any force on the anchor element 23.1 of the anchor device 22.
Figure 4c shows the case that the fastening device 20 is deformed by the action of fire so that the bearing device 32 has moved away from the winding shaft 18.
the winding shaft 18 is no longer resting on the bearing rollers 34.1, 34.2, but is held by the anchor elements 23, in particular by the anchor element 23.1.
the winding shaft 18 exerts a pure tensile force on the anchor elements 23.
the fire or smoke protection device 10 comprises, as is generally the case in a preferred embodiment, a sealing strip 56, which abuts the winding shaft and / or the partitioning element 16 in the event that the winding shaft 18 is held by the anchor device 22. This prevents smoke from passing from a first side 58 of the building opening 12 to a second side 60, so that the fire or smoke protection device 10 prevents smoke from passing through the building opening 12.
FIG. 5a shows a fire or smoke protection device 10 according to the invention in the form of a roller door, in which the partition element 16 is formed by a slatted curtain of mutually articulated slats elements 62.1, 62.2, ....
the lamellar elements 62 are fastened to the winding shaft 18.
the anchor device 22 includes a catch hook 64 which is disengaged from the winding shaft 18 when the partition member 16 is not in the protection arrangement. For example, the fishing hook 64 then slides on the slatted curtain.
FIG. 5b shows the case in which the partitioning element 16 is in its protective arrangement.
the catch hook 64 then surrounds the winding shaft 18 at least in sections and thus interacts with the winding shaft 18 in a form-fitting manner.
the winding shaft 18 is held by the bearing device 32. The connection between the fishing hook 64 and the winding shaft 18 and thus the positive connection is not activated.
FIG. 5c shows the case in which the bearing device 32 due to a deformation of the fastening device 20, the winding shaft 18 can not hold.
the winding shaft 18 depends on the fishing hook 64 and the positive connection is activated.
