Description

The invention relates to a fire protection flap with a housing for a shut-off flap mounted therein so that it can pivot about a pivot axis, and with an installation kit surrounding the housing on the outside, the installation kit comprising at least one plate, preferably at least two plates arranged adjacent to one another, with each plate having at least two plate segments and is designed in such a way that all of the plate segments of the respective plate form a recess for accommodating the housing, with each plate segment being attachable laterally from the outside, in particular in the radial direction, around the housing, and with the associated plate segments of each plate adjoining touch two abutting edges with the or the other plate segment (s), wherein the housing is further surrounded on the outside of at least one frame.

the EP 2 570 158 A1 discloses a generic fire damper with the features of the preamble of claim 1.

Each frame has a closed recess for receiving the housing. The housing is pushed into the recess at the factory, and the frame is fixed to the housing using suitable fastening material. The assembly proves to be disadvantageous, since the closed design of the frame means that the housing is first pushed into the recess and then the required number of plate segments depending on the number of plates to be achieved around the housing placed around.

The object of the invention is to avoid the aforementioned disadvantages and to specify a fire damper whose installation kit can be installed more easily and quickly.

According to the invention, a fire damper with the features of claim 1 is proposed to solve this problem. According to the invention, it is provided that each frame comprises at least two frame segments and each frame is designed in such a way that all of the frame segments of the respective frame form a recess for receiving the housing, with each frame segment being wrapped around the housing laterally from the outside, in particular in the radial direction can be attached around, wherein the cooperating end regions of two adjacent frame segments are provided without overlapping in a direction orthogonal to the plane spanned by the frame segments of this frame, adjoining and touching each other and wherein furthermore the cooperating end regions of two adjacent frame segments are indirectly fixed by at least one separate fixing element in Reference to a relative movement are fixed to each other in at least one direction, each frame segment of two adjacent frame segments in its respective end portion, which is connected to the end portion of the adjacent frame segments s interacts, in each case has at least one insertion area that is laterally accessible from the outside, preferably an insertion area designed as an insertion opening, and that the two end areas of these two adjacent frame segments are secured by at least one clamp designed as a fixing element, which has a partial area in at least one insertion area of the one frame segment and with another partial area in at least one insertion area of the other frame segment engages, are fixed.

The configuration according to the invention permits simple assembly since only the required number of frame segments must be placed laterally around the housing from the outside in such a way that the cooperating end regions of two adjacent frame segments are provided adjoining and touching one another without overlapping. The cooperating end regions of two adjacent frame segments are indirectly fixed by at least one separate fixing element with respect to a relative movement to one another in at least one direction.

The cooperating end regions of two adjacent frame segments adjoin one another without overlapping in a direction orthogonal to the plane spanned by the frame segments of this frame. As a result, the interacting end regions of two adjacent frame segments of a frame, seen in the direction of flow, do not overlap. The frame segments can abut one another or interlock, for example, in the manner of jigsaw puzzle pieces.

The installation kit of the fire damper according to the invention can thus be assembled on site.

Storage can also be facilitated by the configuration according to the invention. Only the fire damper needs to be stocked. The components for creating the desired installation set, i.e. the plate segments and the frame segments, can be stored separately from this. The installation kit can then be put together and installed on site in the desired configuration.

The cooperating end regions of two adjacent frame segments are indirectly fixed by at least one separate fixing element with respect to relative movement to one another in at least one direction, each frame segment of two adjacent frame segments having in its respective end area, which interacts with the end area of the adjacent frame segment, at least one insertion area that is laterally accessible from the outside, preferably an insertion area designed as an insertion opening, and that the Both end areas of these two adjoining frame segments are fixed by at least one clamp designed as a fixing element, part of which engages in at least one insertion area of one frame segment and another part in at least one insertion area of the other frame segment. For assembly in such an embodiment, only the frame segments, which together form a frame, have to be placed around the housing. Each clamp is then inserted from the outside, ie radially to the housing and thus orthogonally to the direction of flow in the housing, into the corresponding insertion area and the two end areas of two adjacent frame segments are thus fixed to one another. If a frame consists of two frame segments, two brackets are required.

At least one plate segment and at least one adjacent frame segment, which in the state in which they are placed on the housing are arranged so that at least half of their surface area is in contact with one another, can be be fixed to the outside of the housing already under each other. If at least one plate segment and at least one adjacent frame segment are already fixed to one another, the installation kit can be assembled in the form of blocks. The "pairing" of plate segment and adjacent frame segment can be arbitrary in terms of number and sequence. A pairing can consist, for example, of a plate segment and an adjacent frame segment. Other configurations, such as a plate segment and several frame segments, are also possible. If, for example, the housing has a rectangular cross section and, for example, the respective interacting end areas of two adjacent frame segments are arranged in the area of one of the four corners of the housing, four blocks are first produced by fixing the required number of plate segments and frame segments to one another, for example by screwing will. The number and arrangement of the frame segment(s) and/or plate segment(s) is the same for all four blocks. The blocks are then placed on the housing in such a way that the interacting end regions of two adjacent frame segments are either fixed directly in relation to a relative movement to one another in at least one direction or alternatively are indirectly fixed in relation to a relative movement to one another in at least one direction by at least one separate fixing element . The assembly time can be reduced by the block assembly. The installation kit produced in this way also has a high level of stability.

In a preferred embodiment, all plate segments and their respective adjacent frame segments, which are arranged in contact with the housing with at least half of their surfaces lying against one another, can be fixed to one another before they are placed on the outside of the housing. This configuration in turn allows the installation kit to be assembled in the form of blocks. The "pairing" of plate segment and adjacent frame segment can be arbitrary in terms of number and sequence. A pairing can consist, for example, of a plate segment and an adjacent frame segment. Other configurations, such as a plate segment and several frame segments, are also possible. If, for example, the housing has a rectangular cross section and, for example, the respective interacting end regions of two adjacent frame segments are arranged in the area of one of the four corners of the housing, four blocks are first produced by the required number of plate segments and frame segments being fixed to one another, for example by screwing . The number and arrangement of the frame segment(s) and/or plate segment(s) is the same for all four blocks. The blocks are then placed on the housing in such a way that the interacting end regions of two adjacent frame segments are either fixed directly in relation to a relative movement to one another in at least one direction or alternatively are indirectly fixed in relation to a relative movement to one another in at least one direction by at least one separate fixing element .

At least one frame can consist of a flat and evenly formed metal sheet. The frame thus has a small thickness. The sheet metal is made of a suitable metal such as steel or iron. Of course, other suitable metals are also conceivable. The metal sheet is in contact with the outside of the housing with its inner edge facing the housing and forming the recess and extends orthogonally to the housing.

At least one clip can consist of a preferably flat and planar sheet metal. The sheet metal is made of a suitable metal such as steel or iron. Of course, other suitable metals are also conceivable.

The frame and at least one bracket of this frame, preferably all brackets of this frame, can have the same thickness.

At least one clamp can have a U-shaped configuration, forming a web and two fixing legs formed thereon and preferably aligned parallel.

The frame segments of two adjoining frame segments can form a common receiving area in their adjoining end areas for receiving a partial area of the clip, preferably the web of the clip. The recording area is accessible from the outside from the side. In the inserted state, for example, the web of the clip is in the receiving area, so that the clip does not protrude laterally beyond the outer contour of the frame in its fixing position.

It is advisable if, in the case of at least one clamp, each of the two fixing legs has an inner surface, with the inner surfaces of both fixing legs being aligned facing one another, and if, in the case of at least one clamp, the distance A between the two inner surfaces from the free end of each fixing leg to the jetty, d. H. Seen against the direction of insertion, reduced at least in a partial area. Thus, the fixing legs can be aligned so as to run towards one another, viewed from their free end towards the web. In the case of an embodiment as a flat metal sheet, it is advisable if the width of at least one fixing leg increases in the region of the edge that faces the other fixing leg and forms the inner surface. If the distance A between the two inner surfaces is only reduced in a partial area, the inner surfaces are aligned in parallel in the remaining partial area.

It is also useful if each insertion area has an active surface, with the active surfaces of the interacting end regions of two adjacent frame segments pointing away from one another in the fixed state and being arranged at a distance B from one another.

In the fixed state of the interacting end regions of two adjacent frame segments, the distance A can correspond to the distance B at most.

In this case, at least one active surface of a frame segment, preferably both active surfaces of two adjacent frame segments, can be designed at an angle at least in a partial area such that the distance B is in the direction of insertion seen increases at least in the sub-area. If the sloping configuration only extends to a partial area, the two active surfaces of the two adjacent frame segments are aligned in parallel in the remaining partial area.

To make it easier to insert a fixing leg into the insertion area, it is advisable if at least one fixing leg tapers towards its free end.

At least one of the two frame segments of two adjacent frame segments can have in its end area at least one projection pointing in the direction of the end area of the second frame segment, and the end area of the second frame segment that interacts with said end area of the first frame segment can have at least one receiving area corresponding to the projection, see above that when the projection engages in the corresponding receiving area, a displacement of the two adjoining frame segments orthogonal to the blocking direction of the two ends of the frame segments, which are preferably fixed by the clamp, is prevented.

When assembled, at least one frame can have the same dimensions as at least one of the two immediately adjacent panels.

At least one plate can be arranged on both sides of at least one frame.

At least one plate can contain silicates, in particular calcium silicate. Of course, other suitable materials are also conceivable.

The same reference numbers are used in all figures for the same or similar components.

the figures 1 and 3 show two different exemplary embodiments of a fire protection flap with a housing 1 for a shut-off flap 2 mounted therein so that it can pivot about a pivot axis. Each fire damper has an installation kit on the outside, which includes at least one plate 4 and a frame 5 .

Each plate 4 is made of silicate, for example, and in the embodiment shown in FIG figure 1 of two plate segments 4a, which are designed in such a way that the entirety of both plate segments 4a of the respective plate 4 forms a recess for accommodating the round housing 1. Each plate segment 4a can be fitted around the housing 1 laterally from the outside in the radial direction. The associated plate segments 4a of each plate 4 touch the other plate segment 4a at two abutting edges, a seal being provided in the area of the abutting edges.

In the embodiment according to 1 five plates 4 are provided, with a frame 5 being arranged between the second plate 4 and the third plate 4 . At least one plate 4 is thus arranged on each side of the frame 5 .

In the embodiment according to Figures 3 to 6 Each plate 4 consists of four strip-shaped plate segments 4a, which are designed in such a way that the entirety of all plate segments 4a of the respective plate 4 forms a rectangular recess for accommodating the rectangular housing 1.

In the embodiment according to 3 four plates 4 are provided, with the frame 5 being arranged between the first plate 4 and the second plate 4 . The four plates 4 have different heights and different thicknesses. On both sides of the frame 5, a plate 4 is also arranged in this embodiment. In the embodiment after 4 the front plate 4 in this representation also has an insulating layer 7 on its surface interacting with the housing 1 . The frame 5 in the embodiment according to Figures 1 and 2 comprises two frame segments 5a, which are designed in such a way that the entirety of all frame segments 5a of the frame 5 forms a recess for receiving the round housing 1, each frame segment 5a being attachable laterally from the outside, in the radial direction, around the housing 1. The frame 5 in the embodiments according to Figures 3 to 9 comprises four frame segments 5a, which are designed in such a way that all of the frame segments 5a of the respective frame 5 form a recess for receiving the rectangular housing 1, with each frame segment 5a being attachable laterally from the outside, in the radial direction, around the housing 1.

As can be seen from the figures, each frame 5 consists of a flat and planar sheet metal, such as steel or iron. The sheet metal is in contact with the outside of the case 1 and extends orthogonally to the case.

The fixation of the frame segments 5a of the frame 5 is particularly in the Figures 7 to 9 shown. The cooperating end portions of two adjacent frame segments 5a are provided without overlap in a direction orthogonal to the plane spanned by the frame segments 5a of this frame 5, adjoining and touching each other. As a result, the interacting end regions of two adjacent frame segments 5a of a frame 5, viewed in the flow direction 20, do not overlap.

The cooperating end portions of two adjacent frame segments 5a are in the example not belonging to the invention 7 directly in relation to a relative movement to each other in at least one direction (blocking direction) 8 fixed. At the in 7 shown embodiment engage the cooperating end portions of two adjacent frame segments 5a in the manner of jigsaw puzzle pieces. At the in 7 shown configuration one frame segment 5a of two adjacent frame segments 5a has in its respective end area, which interacts with the end area of the adjacent frame segment 5a, an insertion area 10 open to the outside and the adjacent frame segment 5a in its end area has an insertion section 19 corresponding to the insertion area 10. In the state attached to the housing 1, as in the example not belonging to the invention

7 is shown, the insertion section 19 provided in the end area of one frame segment 5a is inserted into the insertion area 10 of the adjacent frame segment 5a. The insertion section 19 can also have a different shape, for example in the manner of an arrow. The insertion area 10 then has a corresponding configuration.

In the embodiments, for example, according to figure 5 , 8 or 9 the cooperating end regions of two adjacent frame segments 5a are fixed indirectly with respect to a relative movement to one another in at least one direction (blocking direction) 8 by a separate fixing element, which is designed as a U-shaped clamp 9 .

Each frame segment 5a of two adjoining frame segments 5a has in its respective end area, which interacts with the end area of the adjoining frame segment 5a, an insertion area 10 that is laterally accessible from the outside. The two end areas of these two adjoining frame segments 5a are each connected by a clamp 9 designed as a fixing element, which with its one part, namely a first fixing leg 11, in the insertion area 10 of the one frame segment 5a and with its other part, namely a second fixing leg 12, engages in the insertion area 10 of the other frame segment 5a, fixed.

Since the frame 5 is in the form of sheet metal, each insertion area 10 is in the form of a slot-shaped recess which is laterally delimited by the two adjacent plates 4 . Each bracket 9 is made of a flat and planar sheet metal such as steel or iron. Each clamp 9 has a U-shaped configuration, forming a web 13 and two fixing legs 11, 12 formed thereon and parallel in terms of their general alignment.

At the in the 10 and 11 brackets 9 shown, the distance A between the two fixing legs 11, 12 is reduced from the free end of each fixing leg 11 or 12 to the web 13. When designing 10 the reduction of the distance A occurs counter to the direction of insertion 24 in the partial area of the inner surfaces 22, 23 adjoining the free ends of the fixing legs 11 and 12, while the inner surfaces 22, 23 run parallel in the partial area adjoining the web 13. In 11 an inverted arrangement is shown. Here the inner surfaces 22, 23 initially run parallel in the partial area adjoining the free ends, while the inner surfaces 22, 23 in the partial area adjoining the web 13 are designed to run obliquely towards one another, viewed counter to the insertion direction 24. Like the 10 and 11 it can be seen that the respective insertion area 10 and the clip 9 that interacts with this insertion area 10 are designed to correspond.

At the in 11 In the configuration shown, the active surfaces 21 , which are oriented obliquely towards one another when viewed counter to the insertion direction 24 , cause two adjacent frame segments 5a to be pulled towards one another when the clip 9 is inserted into the two insertion regions 10 .

The interaction of the partial area of the clip 9, in which the inner surfaces 22, 23 run parallel, on the one hand, and the partial area of the insertion area 10, in which the active surfaces 21 run parallel, on the other hand, prevents the clip 9 from being unintentionally released.

To facilitate the insertion of the fixing legs 11, 12 into the respective insertion area 10, the inner surfaces 22, 23 in the partial area adjacent to the free ends of the fixing legs 11 and 12 - as shown in 10 is shown - viewed against the direction of insertion 24 facing each other obliquely and / or the active surfaces 21 - as it is in 11 is shown - be aligned opposite to the insertion direction 24 facing each other obliquely.

Like the Figures 1 and 2 can be seen, the clip 9 does not protrude laterally in relation to the outer contour of the frame 5 in the fixed state. The reason for this is that the two adjacent frame segments 5a form a common receiving area 18 in which the web 13 of the clamp 9 is located when the clamp 9 is in the fixing position.

In the embodiment according to the Figures 5 to 8 one of the two frame segments 5a of two adjacent frame segments 5a has in its end area at least one projection 14 pointing in the direction of the end area of the second frame segment 5a. The end region of the second frame segment 5a that interacts with said end region of the first frame segment 5a has a receiving region 15 that corresponds to the projection 14, so that when the projection 14 engages in the corresponding receiving region 15, the two adjoining frame segments 5a are displaced orthogonally to the blocking direction 8 of the two ends of the frame segments 5a fixed by the clamp 9 is prevented.

The example in figure 5 shown embodiment allows a "block assembly" of the kit. The installation kit consists of four blocks. Each block in turn consists of a frame segment 5a and several plate segments 4a. The frame segment 5a and the plate segments 4a of a block are arranged in contact with the housing 1 with at least half of their area lying against each other. Before applying a block to the outside of the housing 1, the frame segment 5a and the plate segments 4a of this block are fixed to one another by screwing. The number and arrangement of the frame segment 5a and the plate segments 4a is the same for all four blocks. The housing 1 has a rectangular cross-section and the respective cooperating end regions of two adjacent frame segments 5a are arranged in the region of one of the four corners of the housing 1. After making the four Blocks are placed on the outside of the housing 1 in such a way that the interacting end regions of two adjacent frame segments 5a are each fixed by a fixing element. The blocks can be delivered to the site prefabricated and assembled on site in the manner previously described to form a kit.

As for example in the figures 2 or 4 can be seen, the frame 5 can have the same dimensions as the two immediately adjacent panels 4 in the assembled state. The frame 5 and also the brackets 9 are thus better protected by the adjoining plates 4 against high temperatures, for example.

In the exemplary embodiments, for example 2 the frame 5 and the two brackets 9 of this frame 5 have the same thickness. To this extent, the two frame segments 5a of this frame 5 and the two brackets 9 form a flat and very thin component. In this way, each clip 9 is in contact with the two adjoining plates 4 in the inserted state and is secured by clamping against accidental falling out.

As for example in 2 can be seen, holes 16 can be provided in the installation kit, can be screwed through the screws. The screws 17 can serve the purpose of screwing the plates 4 and the frame 5 together. The screws can also be used to attach the fire damper in an opening in a wall, not shown. The abutting edges of adjacent panels 4 and of the frame 5 can be aligned with one another or offset from one another.

The fire damper according to the invention allows for easy assembly. Depending on the number of plates 4 desired, only the number of plate segments 4a required for this purpose has to be placed around the housing 1 and the plate segments 4a of each plate 4 fixed against one another. The frame segments 5a for the frame 5 are then placed around the housing 1 at the desired location. Using the brackets 9 the adjacent plate segments 5a are fixed. Once the installation kit has been completed, the fire damper can be installed. Alternatively, the basis of figure 5 explained block assembly possible.

In order to avoid unintentional loosening of the installation kit, it is possible to design the frame 5 according to, for example, 7 or 9 when the installation kit has at least two corresponding frames 5, with two frames 5 being arranged mirror-inverted to one another, ie the arrangement of the end regions of the relevant frame segments 5a and the brackets 9 of these two frames 5 are not arranged in alignment with one another as seen in the direction of flow 20.

In the 10 and 11 the operating principle of a fixing element is shown again. The frame segments 5a each have an insertion area 10 that is laterally accessible from the outside. Each frame segment 5a has an active surface 21 which extends from the free end of the relevant fixing leg 11 or 12 to the web 13. In the fixing position of the respective fixing element, the active surface 21 interacts with the corresponding area, ie the active surface 22 or 23, of the fixing element. In 10 the fixing element is designed as a U-shaped bracket 9 . The two effective surfaces 21 of the cooperating end regions of two adjacent frame segments 5a point away from one another and are arranged at a distance B from one another--if the cooperating end regions of the two adjacent frame segments 5a are in contact.

For the sake of simplicity, in 11 two possible configurations of a separate fixing element are shown. The upper fixing element is designed as a kind of wire clip, which has an oval shape and is interrupted in the area of one of its two long sides, forming two free ends. A fixing element designed as a U-shaped clamp 9 is shown underneath.

In the case of the fixing element, which is designed as a type of wire clip, the two free ends are arranged at a distance A from one another. The wire clip is preferably designed in such a way that it can be expanded a little against a restoring force. In the fixed state, one free end of the clip engages in the insertion area 10 of one frame segment 5a and the other free end of the clip engages in the insertion area 10 of the other frame segment 5a. If the cooperating end regions of the two adjacent frame segments 5a, as is the case for example in 11 is shown, are in contact with the respective active surface 21, with the fixing element in the fixing position, the distance A is at most as large as the distance B. The frame segments 5a are thus pulled against one another by the fixing element when it is in its fixing position .

In the fixing element, which is designed as a U-shaped bracket 9 and, for example, in the 10 and 11 is shown, in the fixed state the first fixing leg 11 engages in the insertion area 10 of one frame segment 5a and the second fixing leg 12 in the insertion area 10 of the other frame segment 5a. In the case of the clamp 9, the distance A, viewed counter to the direction of insertion 24, is reduced in a partial area between the two inner surfaces 22, 23 of the fixing legs 11, 12, which face one another and are oriented at an angle in the relevant partial area, from the free end of each fixing leg 11 or 12 to the web 13 towards Each insertion area 10 has an active surface 21, the active surfaces 21 of the interacting end regions of two adjacent frame segments 5a pointing away from one another in the fixed state and being arranged at a distance B from one another. The two effective surfaces 21 of the interacting end areas of the two adjacent frame segments 5a are also aligned obliquely in a partial area.

When inserting the clip 9 in the insertion direction 24 into its fixing position, the design pushes down 10 the obliquely aligned inner surfaces 22, 23 of the fixing legs 11, 12 on the active surfaces 21 of the cooperating end regions of two adjacent frame segments 5a, so that the two adjacent frame segments 5a are pulled towards one another. When designing 11 cause the inclined active surfaces 21 of the cooperating end regions of two adjoining frame segments 5a, that the frame segments 5a are moved towards one another when the clamp 9 is inserted.

Fire door according to any one of the preceding claims, characterised in that each introduction region (10) comprises a working surface (21), wherein the working surfaces (21) of the interacting end regions of two adjacent frame segments (5a) face away from one another in the fixed state, and are arranged at a distance interval B from one another.
11. Fire door according to claims 9 and 10, characterised in that, in the fixed state of the interacting end regions of two adjacent frame segments (5a), the distance interval A corresponds as a maximum to the distance interval B.
12. Fire door according to any one of claims 10 or 11, characterised in that at least one working surface (21) of a frame segment (5a), and preferably both working surfaces (21) of two adjacent frame segments (5a), are configured in at least one part region as oblique, in such a way that the distance interval B, seen in the introduction direction (24), increases at least in the part region.
13. Fire door according to any one of claims 7 to 12, characterised in that at least one fixing limb (11, 12) tapers towards its free end.
14. Fire door according to any one of the preceding claims, characterised in that one of the two frame segments (5a) of two adjacent frame segments (5a) comprises, in its end region, at least one projection (14), pointing in the direction of the end region of the second frame segment (5a), and the end region of the second frame segment (5a), interacting with the said end region of the first frame segment (5a), comprises at least one receiving region (15) corresponding to the projection (14), such that, at the engagement of the projection (14) into the corresponding receiving region (15), any displacement is prevented of the two adjacent frame segments (5a) orthogonally to the blocking direction (8) of the two ends of the frame segments (5a) fixed by the clamps (9).
15. Fire door according to any one of the preceding claims, characterised in that at least one frame (5) exhibits the same dimensions as at least one of the two immediately adjacent plates (4).
16. Fire door according to any one of the preceding claims, characterised in that, in each case, at least one plate (4) is arranged on both sides of at least one frame (5).
17. Fire door according to any one of the preceding claims, characterised in that at least one plate (4) contains silicates, in particular calcium silicate.
