Definitions

  • the invention relates to an assembly for forming a ceiling to be connected to an upper wall of a building space, comprising hangers with an adjustable length to be fixed to the upper wall, elongate girders consisting of an upper U-shaped channel with an essentially flat bottom and curled terminal edges which are adapted to be removably clamped onto a plurality of said hangers with the opening of the U-shape uppermost, and a lower U-shaped channel with ledges for supporting ceiling panels and with an essentially flat bottom adapted to be placed against the bottom of the upper channel, and to be connected to the latter bottom at the regular distances with the opening of the lower channel directed downwards.
  • the channels are permanently interconnected to form a composite girder, which girder has to be levelled before finally adjusting the hangers in question, the full weight of such a girder has to be supported by the workmen.
  • the lower channels have inwardly directed ledges forming means for snapping on ceiling elements so that said channels are no longer accessible for providing therein electrical wiring, so that separate wiring ducts are to be used in such a ceiling system.
  • An additional advantage of this assembly is that the upper channels can be separately used as cable ducts in places where no ceiling elements are to be supported, thus avoiding the necessity of providing additional parts for this purpose, and in cases of an insufficient height clearance the lower ducts can be used without the upper ones, e.g. by fixing the former directly onto the ceiling or by using adapted clamps or hangers for that purpose.
  • the bottoms of the upper and lower channels are provided with interfitting ribs or slots resp. in order to allow said channels to be mutually aligned.
  • Said coupling elements can be provided, moreover, with laterally extending hooks for supporting wires, which elements can, in particular, be U-shaped, and in the legs thereof recesses for inserting additional wire supporting means can be provided. Wires supported in this manner are easily accessible after removing the closing lid.
  • the lateral walls of the lower channel, where joining the external ledges are slightly bent inwards, the closing lids then being provided with claws with a curvature adapted thereto.
  • the assembly of elements shown in Fig. 1 comprises an upper channel profile 1 with its opening directed upwards, a lower channel profile 2 with the opening directed downwards, a coupling bracket 3, a closing strip or lid, 4 and a hanger 5.
  • the hanger to be connected to an upper wall of a space which should have an adjustable length can be constructed in any suitable manner, e.g. as a vernier hanger, or as one or more rods with screw adjustment or with an adjustable clamp or the like.
  • said hanger comprises a transverse part 6 with two holes 7 (see Fig. 2), to which suspension rods (not shown) can be screwed.
  • the transverse part 6 is connected to a plate part 8 which, in the position of use, is vertically directed, and is, by means of a narrower transverse part 9, connected to an end part 10 directed parallel to the plate 8, and is as wide as the latter, which end part 10 is provided with upwardly directed projections 11.
  • the plane of the end part 10 substantially extends through the axis of the holes 7.
  • two suspension rods are used, in order to obtain a possibly rigid suspension.
  • the upper channel 1 possesses inwardly curled terminal edges 12 and a flat bottom 13 in which two parallel ribs 14 have been pressed.
  • the edges 12 fit around the projections 11, the lower edge of the part 8 then bearing on these channel edges.
  • the hanger 5 can be mounted in a simple and strong manner by inserting the part 10 obliquely into the channel 1, and, thereafter, to turn it in such a manner that the projections 11 are being positioned below the edges 12. If, then, the hanger 5 is rotated into the upward direction, these projections snap into the edges 12, and then the hanger is strongly connected to the channel 1.
  • keyholes 15 are provided at regular distances in the bottom 13.
  • the channel 2 has a flat bottom 16 in which grooves 17 have been pressed, having such dimensions and mutual distances that, if the bottom 16 is positioned against the bottom 13 of the channel 1, the ribs 14 of the latter fit in the grooves 17.
  • keyholes 18 are provided corresponding to the keyholes 15 of the bottom 13, and being situated at the same mutual distances. Besides the holes 15 and 18, holes 19 for passing wires can be provided.
  • the lateral walls 20 of the channel 2 are bent outwardly to form ledges for supporting ceiling panels etc., the connecting part between the walls 20 and the ledges 21 being formed by an inwardly directed bend 22.
  • holes 23 for passing wires are provided at regular distances which can be closed with a lid or can be constructed as windows closed by a rupturable wall.
  • the coupling element 3 is, as shown, substantially U-shaped.
  • the transverse wall 24 thereof is provided, at the upper side, with a claw 25 which, when rotated 90°, can be inserted into the keyholes 15 and 18 of the channels 1 and 2 placed against one another. After being rotated backwards, the element 3 compresses the bottoms 13 and 16 between the transverse wall 24 and the claw 15 strongly against one another.
  • the closing strip 4 has doubled rims 30 forming a rigid supporting rim which, in the mounted condition, will bear against the flanges 21 of a channel 2, the inner end 31 thereof being turned upwards and being curved so that it will resiliently bear against a bend 22 of the channel 2.
  • Fig. 3 shows the various elements in the assembled condition.
  • the space 32 inside the channel 1 below the lower edge of the hanger 5 can be used for wires which, if required, can be led outwards through the holes 19 or through the upper opening of the channel.
  • the inner space 33 of the channel 2 can also be used for taking up wires which, after removal of the lid 4, become accessible. These wires can be laid on the ledge parts 28, and, for example, telephone lines or the like can be laid at one side, and wires at the mains voltage at the other side. If required hanger straps 34 can be hooked into the holes 27, in which straps still other wires can be supported. Moreover in the interior of the coupling element 3 a wiring duct with conductors supported therein in an insulated manner can be secured, in which duct branching plugs can be inserted in the desired points.
  • the channels 1 and 2 consist of a metal, e.g. galvanised iron, which is cheapest. Such channels can be manufactured in a simple and economical manner. In the assembled condition a strong girder is obtained which can support ceiling panels, lamp armatures etc. without bending. Also the cover strips 4 can consist of a metal, in particular galvanised iron, but are generally provided at their outer sides with an enamel layer.
  • a metal e.g. galvanised iron
  • channels 1 are too short, they can be extended in a simple manner by using a coupling piece fitting clampingly in two aligned channel sections 1. Also T or cross pieces can be used for forming transverse connections.
  • a simple cross-connection element having a bottom 36 and walls 37 fitting in an upper channel 1, the terminal edges 38 of the lateral walls 37 being bent inwardly and fitting in the curled edges 12 of a channel 1.
  • transverse piece 39 is present, which is provided with an outwardly curled edge 40.
  • Said transverse piece is slightly longer than the lateral walls 37, this in such a manner that, if the curled edge 40 is hooked on an edge 12 of a channel 1, the channel into which the lateral walls 37 are inserted will be supported at the same height but transversely to the former channel.
  • transverse girders can be provided, e.g. in the form of profiled rodsfitting in marginal recesses of adjoining ceiling panels. Their extremities can be provided with hooks gripping behind the curled edges 12, and it is also possible to provide adapted apertures in the lateral walls of the channels 1 or 2 in which the extremities of such transverse girders or the like are retained against toppling.
  • the longitudinal girders consisting of channels 1 and 2 and bridging a space are, preferably, extended towards an adjoining corridor where the wires provided in the channels 1 and/or 2 can be connected to supply lines.
  • These supply lines are, for instance, supported in cable ducts extending transversely to the channels 1, and can, in a simple manner, be clamped in the edges 12 of these channels, e.g. by means of the hangers shown in Figs. 1 and 2.
  • the cover strip 4 can, if required, be replaced by plates to be clamped on the ledges 21 and bends 22 as well, and serving to fix separating walls, columns with electric contact means or the like.
  • an additional mounting means can be used in the form of a clamping plate 41 to be positioned on the edges of the apertures 23, and being provided with a screw 42 on which a closing plate 43 can be fixed by means of a nut 44.
  • the girders consisting of the channels 1 and 2 are rigid, and can be firmly supported by means of special hangers, which girders have, moreover, a high bending strength, such separating walls, columns and the like can be secured thereto in the above-mentioned manner without difficulties.
  • hangers hooked in an upper channel 1 can be hooked therein without play, a sufficient lateral stability can be obtained when using a strong suspension, in particular by means of two rods or a profiled suspension element, and, in particular, such suspension means can also be used for securing thereto additional elements, e.g. sound insulating partitions or the like, ceilings situated at a different height, e.g. for an adjoining corridor space or the like, additional cable supports and the like. If the hangers are suspended by means of two screw rods which, at the same time, can be used for height adjustment, such additional supports can be fixed thereon at any desired height by means of additional nuts.
  • cover strips 4 at their inner side with a sound attenuating and/or fireproof layer in order to provide an additional suppression of sound transmission and fireproofing respectively.
