Definitions

  • 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.
  • 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
  • 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.
  • the interacting end regions of two adjacent frame segments of a frame 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.
  • 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.
  • 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.
  • 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.
  • the distance A can correspond to the distance B at most.
  • At least one frame 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.
  • each fire damper has an installation kit on the outside, which includes at least one plate 4 and a frame 5 .
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • an inverted arrangement is shown.
  • 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.
  • the respective insertion area 10 and the clip 9 that interacts with this insertion area 10 are designed to correspond.
  • 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 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.
  • 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.
  • 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.
  • Blocks 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
