Description

[0001] The invention relates to a system comprising at least one housing of a component of an air conditioning and / or ventilation system and an installation kit, wherein the housing has four housing sides and four housing edges forming a rectangular, preferably square, cross-section, and wherein the installation kit serves to fasten the housing in a recess of a partition wall, preferably a partition wall consisting of a frame provided with sheathing on both sides.

[0002] In practice, housings are known in which several calcium silicate strips are attached to each of three sides of the housing, arranged one above the other. This creates a collar. When installed, the collar's edge, facing away from the housing, engages in the space between the partition wall panels. If the ceiling sags, the housing and thus the housing itself sag as well, with the collar sliding within the partition wall. This prevents damage. However, manufacturing the collar is complex and also takes place on-site, taking into account the structural conditions, particularly the size of the existing recess in the partition wall.

[0003] The object of the invention is to avoid the aforementioned disadvantages and to provide a system that is structurally simpler with regard to the installation kit for achieving a sliding ceiling connection.

[0004] This problem is solved by the installation kit having a collar comprising three housing sides, the collar consisting of two opposing parallel contact legs and a connecting web connecting the two contact legs, and wherein the two contact legs and the connecting web leave a rectangular area for receiving the housing, wherein, when the housing is arranged in the rectangular area, the two contact legs each bear against one housing side, and wherein, furthermore, parallel to the longitudinal extent of the contact legs, a relative movement is possible between the housing and the collar, i.e.the entire collar, in such a way that the housing can be moved from a position in which a gap extending across the entire housing side is provided between the connecting bridge and the adjacent housing side, towards the connecting bridge, and the height of the gap can be reduced when the housing is moved towards the connecting bridge.

[0005] The four housing sides can consist of four separate wall sections, with two adjacent wall sections being welded together to form a housing edge. Alternatively, the four housing sides can also consist of sections of wall sections. For this, a sheet of metal is bent three times to form three housing edges, with the two free edges then being welded together to form the fourth housing edge.

[0006] The installation kit creates a sliding ceiling connection. This type of kit allows for the accommodation of movement between a ceiling and a partition wall below, preventing damage. Ceiling movement can be caused by settling, heavy loads, or thermal expansion. The installation kit can be pre-assembled at the factory. If, for example, the kit is to be installed on-site in a partition wall consisting of a stud frame clad on both sides, the housing with the surrounding installation kit is attached below the ceiling, flush with the stud frame. The cladding is then installed on both sides, and the collar of the installation kit is permanently fixed to the partition wall, for example, by screws through the cladding.This means that the collar, with its edge area facing away from the respective side of the casing, is located between the two layers of cladding.

[0007] The housing may be fitted with a cover strip on the side of the housing that forms the gap with the connecting web, at least partially covering the gap. This cover strip covers the gap at its highest point, i.e., when the distance between the connecting web and the housing side facing the connecting web is greatest. The cover strip thus completely covers the gap in every position. The cover strip attached to the housing is positioned relative to the collar in such a way that slight and damage-free relative movement of the desired extent is possible between the housing and the mounting kit.

[0008] Preferably, the cover strip is larger than the gap and its edges are preferably in contact with the mounting legs and / or the connecting web. This design makes it more difficult for air to flow and thus also prevents the spread of fire in this area.

[0009] The housing and the collar can be connected to each other via at least one connecting device that allows relative movement.

[0010] At least one connecting device can comprise at least one guide element arranged on at least one of the two housing sides against which a mounting leg rests, which interacts with at least one fixing element connected to the mounting leg.

[0011] At least one guide element can be designed as an elongated slot, and the corresponding fixing element as a pin, preferably a screw, passing through the elongated slot. The length of the elongated slot defines the degree of relative movement between the housing and the mounting kit. When the ceiling is lowered, each pin is displaced within its elongated slot. The elongated slot guides the respective pin, thus guiding the housing relative to the mounting kit.

[0012] In this arrangement, at least one mounting rail can be covered by an insulating strip. Preferably, at least one insulating strip covers the elongated holes and also the pins of the respective mounting rail. Preferably, the at least one insulating strip consists of calcium silicate and is preferably designed as a calcium silicate strip.

[0013] A mounting rail can be arranged on at least one of the two housing sides that interact with a mounting leg. This mounting rail extends orthogonally to the two housing edges enclosing that side and can have at least one elongated hole. The mounting rail can, for example, be formed by one leg of an angle profile. The angle profile is attached to the housing side by its second leg. However, other types of mounting rails are also conceivable. For instance, the mounting rail can also be designed as an external groove created by deforming the housing material. Alternatively, the two opposing mounting rails can form part of a frame made of flat iron, creating a rectangular opening for the housing that is only slightly larger than the housing's external dimensions.

[0014] The component could be a fire damper. However, it could also be, for example, a smoke extraction damper or an air duct.

[0015] The entire collar and / or the cover strip can consist of calcium silicate, preferably calcium silicate strips.

[0016] The collar can be U-shaped.

[0017] The collar can be made from a single piece.

[0018] However, the collar can also be made up of multiple parts, especially three parts.

[0019] The invention also relates to an arrangement comprising a ceiling, a partition wall with a recess adjacent to the ceiling, and a system according to one of the preceding claims for realizing a sliding ceiling connection, wherein the housing is rigidly attached to the ceiling and the collar of the installation kit is attached in the recess of the partition wall, wherein the housing is arranged in the collar of the installation kit when the ceiling has not yet been lowered, such that a gap extending over the entire side of the housing is provided between the connecting web and the adjacent side of the housing.

[0020] The partition wall can consist of a stud frame clad on both sides, and the cladding can accommodate the respective edge area facing away from the housing, of both mounting legs and the connecting web, with the collar being permanently attached to the partition wall. Thus, the collar is larger than the recess in the partition wall. The collar can be attached to the partition wall in the overlapping area.

[0021] The framework can be reinforced in the area of ​​the recess by profiles, in particular by profiles arranged between the two planks.

[0022] The following section explains exemplary embodiments of the invention illustrated in the drawings. The drawings show: Fig. 1 an oblique view of a system according to the invention installed in a partition wall comprising a housing of a component designed as a fire damper, wherein the ceiling of the room has not yet lowered relative to the partition wall, Fig. 1a the detail from Fig. 1, Fig. 1b the detail from Fig. 1, Fig. 1c the detail from Fig. 1, Fig. 2 the object according to Fig. 1, where the ceiling of the room has sunk relative to the room partition wall, Fig. 2a the detail from Fig. 2, Fig. 2b the detail from Fig. 2, Fig. 2c the detail from Fig. 2, Fig. 3 the object according to Fig. 1, Fig. 3a the detail from Fig. 3 in the case of a lowered ceiling and Fig. 3b the detail from Fig. 3 in the case of a ceiling that is not lowered.

[0023] In all figures, identical reference symbols are used for identical or similar components.

[0024] The figures show an arrangement comprising, on the one hand, a ceiling 1 of a room (not shown in detail) and, on the other hand, a partition wall 2 of the room (not shown in detail), wherein a rectangular recess is provided in the partition wall 2 adjacent to the ceiling 1. The partition wall 2 consists of a stud frame clad on both sides with sheathing 3, for example, plasterboard.

[0025] Secondly, the arrangement comprises a system described below, including a housing 4 of a component of an air conditioning and / or ventilation system and an installation kit 5. In the illustrated embodiments, the component is a fire damper with a damper blade 6 in its closed position.

[0026] The housing 4 consists of four housing sides 7 and four housing edges 8, forming a rectangular cross-section. The housing 4 has two housing ends 9. These serve for connecting further components (not shown), such as an air duct. The housing 4 is rigidly attached to the underside of the indicated ceiling 1 by means of a fastening (not shown). If the ceiling 1, for example, sags, the housing 4 sags accordingly.

[0027] The installation kit 5 serves to arrange the housing 4 in the recess of the partition wall 2. The installation kit 5 has a collar comprising three housing sides 7, the collar consisting of two opposing parallel mounting legs 10 and a connecting web 11 connecting the two mounting legs 10 to each other.

[0028] The collar may be made from a calcium silicate board. In this case, the collar is formed in one piece, as in the illustrated embodiment. The collar is U-shaped and larger than the recess in the partition wall 2. Therefore, the panels 3 between them accommodate the respective edge area facing away from the housing 4, of both support legs 10 and the connecting web 11. In the overlapping area, the collar is fixedly attached to the partition wall 2, for example, by means of screws (not shown).

[0029] The collar can also be made up of multiple parts. For example, it can be composed of three interconnected calcium silicate strips. In this case, too, the collar is U-shaped.

[0030] The two mounting legs 10 and the connecting web 11 leave a rectangular area free for receiving the housing 4. When the housing 4 is positioned in the rectangular area, the two mounting legs 10 each rest against a housing side 7, while relative movement between the housing 4 and the collar remains possible parallel to the longitudinal extent of the mounting legs 10.

[0031] In Fig. Figure 3b shows the unlowered position of the ceiling 1 and the housing 4. The housing 4 can be moved from this position, in which a gap 12 extending across the entire housing side 7 with height "H" is provided between the connecting web 11 and the adjacent housing side 7, in the direction of the connecting web 11, i.e., in the direction of arrow 13. When the housing 4 is moved in the direction of the connecting web 11 (arrow 13), the height H of the gap 12 is reduced. Fig. Figure 3a shows the lowered position of the ceiling 1 and the housing 4. The housing 4 is lowered so far within the collar that the housing side 7 facing away from the ceiling 1 touches the connecting web 11 and the height H of the gap 12 is 0 mm. Further lowering is not possible.

[0032] On the housing 4, on the housing side 7 facing away from the ceiling 1, which forms the gap 12 with the connecting web 11, a cover strip 18 is provided that covers the gap 12 and is only visible in the Fig. 1, Fig. 1a and Fig. 1c and Fig. 2, Fig. 2a and c, however not in the Fig. 3, Fig. 3a and Fig. Figure 3b shows that this cover strip 18 is, in the illustrated embodiment, screwed to the housing 4, for example, by means of screws 19. The cover strip 18 completely covers the gap 12 in every position of the housing 4. When the housing 4 is lowered so far within the collar that the housing side 7 touches the connecting web 11, the cover strip 18, with its surface facing the connecting web 11, rests completely against the connecting web 11. Since the cover strip 18 is larger than the gap 12, it is positioned relative to the collar such that its edge area rests as closely as possible against one of the two outer surfaces of each contact leg 10 and of the connecting web 11.

[0033] This allows for good, almost tight coverage of the gap 12 and, at the same time, easy and damage-free relative movement to the desired extent between the housing 4 and the collar.

[0034] The housing 4 and the collar are connected to each other via several connecting devices that allow relative movement. Each connecting device comprises several guide elements 14, each of which interacts with a fixing element 15 connected to a contact leg 10, the guide elements 14 being arranged on the two housing sides 7, on each of which a contact leg 10 rests.

[0035] Each guide element 14 is designed as an elongated hole, and the corresponding fixing element 15 is designed as a pin, shaped like a screw, that passes through the elongated hole. The screw extends through the corresponding elongated hole and is screwed into one of the two mounting legs 10.

[0036] In Fig. 3, Fig. 3a and Fig. For the sake of clarity, neither the insulating strip 17 nor the cover strip 18 are shown in Figure 3b. Since the cover strip 18 is not shown, the gap 12, extending across the entire housing side 7 and located between the connecting web 11 and the adjacent housing side 7, is now visible.

[0037] How in particular the Fig. 3, Fig. 3a and Fig. As shown in Figure 3b, a guide rail 16 is arranged on each housing side 7 that interacts with a guide leg 10. This guide rail extends orthogonally to the two housing edges 8 that enclose the respective housing side 7. In the illustrated embodiment, each guide rail 16 is formed by one leg of an angle profile, the second leg of which is attached to the outside of the housing side 7. Each guide rail 16 has four elongated holes, with each guide leg 10 having a corresponding number of pins designed as screws. The length of the shortest elongated hole defines the extent of the total achievable relative movement between the housing 4 and the collar. When the ceiling 1 is lowered, each pin-designed fixing element 15 is displaced in its guide element 14, which is designed as an elongated hole.

[0038] Of course, other configurations of the mounting rail 16 are also possible. For example, the two opposing mounting rails 16 can also form part of a frame made of flat iron. The frame forms a rectangular opening that is only slightly larger than the outer dimensions of the housing 4. The frame thus surrounds the housing 4 on all four housing sides 7 and preferably fits snugly against the housing sides 7.

[0039] On each of the two mounting rails 16, an insulating strip 17 is screwed on in such a way that the elongated holes and the pins of the respective mounting rail 16 are covered. The insulating strip 17 consists of a calcium silicate strip. In the Fig. 1, Fig. 1a and Fig. 1b as well as in the Fig. 2, Fig. 2a and Fig. Figure 2b shows the mounted insulating strip 17, while it is positioned to better illustrate the relative motion in the Fig. 3, Fig. 3a and Fig. 3b is not shown.

[0040] With the ceiling 1 not yet lowered, the housing 4 is arranged in the installation kit 5 such that a gap 12 extending across the entire housing side 7 is provided between the connecting web 11 and the adjacent housing side 7. This is, for example, Fig. See 3b. The height H of column 12 is at its maximum in this position and is approximately 40 mm.

[0041] If a load is applied to the ceiling 1 from above, the ceiling 1, and consequently the housing 4 mounted below it, lowers to the same extent. As a result, the housing 4 shifts within the collar towards the connecting web 11, i.e., in the direction of arrow 13. Consequently, the height H of the gap 12 between the housing 4 and the connecting web 11 decreases progressively. The position of the housing 4 at maximum lowering is shown in Fig.Figure 3a shows that the housing side 7 facing away from the ceiling 1 touches the connecting web 11. The length L of the shortest elongated hole and the maximum height H of the gap 12 are at least slightly greater than the largest deflection of the ceiling 1 that can be compensated for without damage.
