Definitions

  • the invention relates to a holder for the arrangement of a sprinkler nozzle of a fire extinguishing system in an opening of a suspended ceiling system, wherein the fire extinguishing system comprises a main line to which the sprinkler nozzle is directed downwards via a flexible hose line, wherein on top of the ceiling system to this in the Substantially parallel bridge is provided, which is connected to carriers of the ceiling system, wherein the connection between the bridge and the carrier takes place via a releasable clamping device and wherein the sprinkler nozzle is at least indirectly attached to the bridge.
  • brackets for sprinkler nozzles are known.
  • Exemplary here is the DE-A 197 09 916 listed, in which a bridge consists of a folded sheet metal blank and is also fastened via a sheet-metal connecting elements attached to two carriers by the connecting elements immersed in slots of the carrier. In this state, the connecting elements are bolted to the sheet metal blank and they hold so the bridge with the attached sprinkler nozzle on two carriers form-fitting.
  • the present invention seeks to provide a holder of the type mentioned above, which is characterized by a simple and inexpensive construction and ease of use, and this with different types of carriers.
  • the clamping device consists of a both the carrier and the bridge at least partially encompassing clamp, and that the clamp presses the bridge and the carrier via a common fastening means against each other and thereby determines positively against each other.
  • the fastening means is in this case designed so that it ensures both the determination of the clamp on the bridge and the clamp on the carrier and thereby for a determination of the bridge on the carrier.
  • the bridge consists of a square tube, as for example from the above US-A 2002/066834 is known. This has proven itself in terms of simplicity, stability and cost-effectiveness.
  • the clamp has a lower horizontal T-base and a head profile encompassed by the clamp, hereinafter referred to as flange, and in particular consists of a T-beam with head flange widened in relation to the T-web.
  • the clamp engages under the flange.
  • the advantages according to the invention come to fruition, in that the clamp has two substantially parallel legs and a common clamp base, which carries the screw means, and in that the legs are hook-shaped at their free ends, so that the clamp surrounds the carrier and / or the bridge with the hook-shaped free ends.
  • the fastening means fixed to the clamp consist of a screw
  • the fastening means fixed to the clamp consist of a screw
  • the hook-shaped ends of the clamp need only surround the T-flange of the T-beam.
  • connection of bridge on the one hand and support or support flange on the other hand, which are generally perpendicular to each other, is made possible by the fact that the clamp has a mutual distance, especially in the region of its hook-shaped ends, which is slightly larger than the width of the T-flange , This ensures that the clamp after pushing on the bridge and the flange can then be pivoted so far until the hook-shaped ends engage under the flange. If the clamp is then tightened via the fastening means, then the hook-shaped ends come into operative connection with the flange of the carrier and attach it to the bridge or at one end thereof.
  • the bridge and the beams extend in the same plane or at least in approximately parallel horizontal planes, wherein the bridge and the beams are arranged substantially perpendicular to each other, and wherein the bridge with its ends on two mutually parallel beams is attached.
  • the carrier form a frame in which cassette-shaped ceiling elements are inserted, and the bridge serves to position the sprinkler nozzle so that it projects through such a ceiling element through an approximately positioned in the center of the ceiling element opening.
  • the attachment of the sprinkler nozzle to the bridge is effected by arranging a sleeve between the hose line and the sprinkler nozzle, and by fastening the sprinkler nozzle to the bridge by loading the sleeve and by means of a clamp encompassing the sleeve on the one hand and the bridge on the other hand.
  • the bracket has two legs, each with a recess for the sleeve and a leg base connecting the two legs, which has a fastening means acting on the bridge, which advantageously consists of two parallel acting on the bridge and bracing against the sleeve screws.
  • FIG. 1 shows a holder 1 for a ceiling system 2.
  • the ceiling system has a plurality of carriers 3, which form a lattice-like structure of a plurality of perpendicular to each other arranged carriers, said carriers having an inverted T-profile, wherein at the in Figure 1 lower T-base 3a individual (not shown) cassette-shaped ceiling elements are set in a conventional manner.
  • a vertical T-web 3b of the T-beam 3 extends upwards and ends there in a flange 3c which has a width which is greater than the T-web 3b and thus closer to being acted upon by the following described holder 1 is used.
  • the holder 1 consists essentially of a bridge 4 in the form of a square tube, which extends between two T-beams 3 and is fixed thereto.
  • the bridge 4 carries in a section, not shown in Figure 1, a clip that defines a precisely not shown sprinkler nozzle positionally so that the sprinkler nozzle protrudes through an opening provided in the cassette-like ceiling element opening.
  • various arrangements and designs in the prior art are already known, so that will not be discussed further here at this point.
  • the holder 1 also consists of a clamp 5, the two vertical clamp legs 5a, 5b and the two clamp legs connecting common clamp base 5c. having.
  • the clamp legs 5a, 5b are formed at their free ends 5d, 5e hook-shaped curved towards each other and form holding portions which act on the T-beam 3 in the region below the flange 3c so that the holding portions of the clamp 5 in the transition region from the T-bridge 3b in the T-flange 3c abut.
  • a screw 6 is arranged in the vertical direction, which acts on the upper side of the bridge 4 and upon further tightening by the free ends 5d, 5e of the clamp legs 5a, 5b forms an abutment against which the screw 6, the bridge 4th braced.
  • the clamp 5 engages around the bridge 4 on the one hand and the T-flange 3c of the T-beam 3 on the other hand and defines both against each other positively.
  • FIG. 1c An essential aspect of the clamp 5 can be seen from Figure 1c: There one sees in a sectional view from above the free ends 5d, 5e of the clamp legs 5a, 5b and recognizes that the clamp consists only of a flat sheet metal blank, thereby engaging the T-flange 3c passes that the clamp is first attached to the support 3 and then JOd far (about 20 °) is rotated about its vertical axis until the hook-shaped slightly bent away from the vertical plane free ends 5d, 5e of the clamp legs 5a, 5b rest under the flange 3c. If the square tube of the bridge 4 is subsequently inserted and the screw 6 tightened, the inclined clamp 5 ensures the mutual clamping of the T-bar and bridge.
  • Figure 1 b shows the clamp 5, the bridge 4 and the T-beam 3 in the side view to Figure 1 a.
  • a vertical distance a v between the upper edge of the hook-shaped free end 5 d and the lower edge of the clamp base 5 c is indicated.
  • this vertical distance must be at least as large as the vertical height of the bridge 4 and the T-flange 3c added together. If you want to provide a clamp that is suitable for different types of carriers, so it is appropriate to choose the distance a v so large that remains for the usual head flange height of between 4 mm and 15 mm, with common bridge heights are taken into account have to.
  • the advantage of the present invention is therefore to provide a holder which can be used for any carrier system by means of a clamp having a sufficient distance a v .
  • the flange width b F shown in FIG. 1 a which must be taken into account in the size of the horizontal distance a h between the free hook-shaped ends 5d, 5e shown in FIG. 1c.
  • the distance a h must be greater as the width b F of the T-flange 3 c, to allow attachment of the clamp on the T-flange of the carrier 3.
  • Figure 2 shows in the views a), b) and c) a holder 11 with a clamp 15, the same bridge 4 and the same T-carrier 3 with the same screw means 6 applied.
  • the clamp 15 has, in contrast to the clamp 5 of Figure 1 no flat flat structure, but a structure as a total almost cuboid U-profile with two substantially L-shaped clamp legs 15a, 15b, in which the free ends 15d, 15e also hook-shaped are formed and the T-flange 3c similar to the hook-shaped free ends 5d, 5e of the clamp 5 and engage under.
  • the attachment of the clamp 15 on the T-flange 3c of the support 3 is made possible, similar to the clamp 5 of Figure 1, characterized in that the clamp is so inclined until the distance between the two hook-shaped ends 15d, 15e is greater than that Width of the T-flange 3c, whereupon the clamp 15 can be plugged onto the T-flange 3c.
  • the clamp is so inclined until the distance between the two hook-shaped ends 15d, 15e is greater than that Width of the T-flange 3c, whereupon the clamp 15 can be plugged onto the T-flange 3c.
  • FIG. 3 shows, in the views a), b) and c), an embodiment of a holder 21 with a clamp 25 almost identical to the embodiment of FIG. 2, with the only difference being that there in the region of the clamp legs 25a, 25b and part of the clamp base 25 c bead-like substantially vertical recesses 25 f, 25 g are attached, which serve to reinforce the rigidity of the clamp legs 25 a, 25 b and rests on the clamp 25 on the square bar of the bridge 4. Otherwise, the structure and function of the clamp 25 is identical to the clamp 15th
  • FIG. 4 shows, in the views a), b) and c), a holder 31 with a clamp 35 which is constructed similarly to the clamps 15 and 25 from FIGS. 2 and 3, but whose clamp base 35c is arranged not horizontally but slightly inclined is.
  • This slope serves to insert a mounting wedge 36 with a correspondingly inclined upper side 36a into the space between clamp base 35c and bridge 4 and thus to clamp the bridge 4 with the T-beam 3 in the vertical direction, again with the free ends 35d, 35e of the clamp legs 35a , 35b act on the T-bar 3b laterally and engage under the T-flange 3c.
  • FIGS. 1 to 4 each have in common that they are in the view a) a front view, in the view b) a side view and in the view c) a partially sectioned view (in Figure 1c) and a plan view (in the figures 2c , 3c and 4c) show.
  • the sleeve is - as here - formed with a 6- or 8-Kant, so provided in U-legs 41a, 41b of the U-bracket recesses 46 adapted thereto have similar bevels, so that with appropriate fixing the sleeve to the bridge can be accommodated without great holding forces by the positive connection between the recess and sleeve comparatively large torques.
  • the embodiments shown show only some variants of the clamping device according to the invention as part of the Sprinklerdüsenhalterung, which is common in the invention that one can fix the bridge to the carrier using a single fastener, this clamping device also very easy from a flat sheet metal blank or consists of a U-shaped bent sheet metal profile.
