Definitions

  • ceilings For forming ceilings at a given distance from the upper wall of a space,many assemblies of elements have become known. Such ceilings are often used in office buildings and the like, and above the ceiling remains a free space for wiring and the like, and the height of the ceiling can be freely chosen. Often the separation walls between different spaces can be chosen freely too.
  • An example of such an assembly comprising hangers with an adjustable length to be fixed to the upper wall, hollow longitudinal girders with outwardly extending ledges for supporting ceiling panels, if required utilising transverse girders extending between the longitudinal girders, means for coupling said hangers with the longitudinal girders, means provided in the hollow longitudinal girders for supporting wires, and closing lids which can be snapped at the lower side into the cavity of the longitudinal girders, can be found in NL-A 8002018.
  • the longitudinal girders are, there, formed by two profiled rods with a cross-section resembling that of a railway rail, which profiled rods are fixed in a mutually parallel manner by means of coupling pieces each forming part of a hanger and gripping around said profiles, and, furthermore, being provided with lateral extensions which are to be inserted through slots in the girder profiles, and are fixed therein by means of bent tabs.
  • Said girder profiles define, in this manner, a hollow space in which a wire duct can be suspended in recesses of the coupling pieces, and said coupling pieces can support, at their upper sides, additional wires or the like.
  • the outer flanges of the girder profiles serve as supports for the ceiling panels, and closing lids can be fixed on the inner flanges.
  • a draw-back of this known system is that assembling the girder profiles is rather time consuming, since at each coupling piece four fixing tabs are to be bent, and, moreover, such a tab connection can never be absolutely rigid so that always a certain longitudinal play will remain in the assembled girder. This can considerably hamper the connection of heavier objects to or the suspension thereof on such an assembly.
  • electric wires can be accommodated, but then they will not or only difficultly be accessible from below, so that ceiling panels are always to be removed in order to allow said wires to be reached from above.
  • each longitudinal girder consists of a first U-shaped channel with a flat bottom and curled terminal edges which can be clamped on a plurality of hangers with its opening directed upwards, and a second U-shaped channel with a flat bottom which, with its bottom directed upwards, is placed against the bottom of the first channel, keyholes being provided at regular distances in the bottoms of both channels into which a coupling element provided with claws can be inserted and can be locked by rotation in order to interconnect both channels, the terminal edges of said second channel being provided with external ledges, and at least the second channels being adapted for accommodating wires.
  • Such channel profiles can be manufactured in a simple and economic manner, and mutually coupling both channel profiles by means of the coupling elements, after having secured the first channels together with the hangers on the upper wall and having aligned said channels, can be done very quickly, and the channels thus interconnected form a profiled girder having a high bending strength in which no play will occur, and, in particular, also heavier objects can be secured thereto or suspended thereon.
  • girders for forming a ceiling consist of two substantially U-shaped channels placed with their flat bottoms against one another.
  • said channels are permanently interconnected by means of rivets, and must, therefore, be suspended as a unit.
  • the girders according to the invention consist of separate channels, and, initially, only the upper ones are to be suspended, after which the lower ones can be connected to the former ones by means of the coupling elements. This considerably simplifies the suspension work, since the separate channels are substantially lighter than the assembled known girders.
  • first and second 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 a second channel, where joining the external ledges are slightly bent inwards, the closing lids then being provided with claws with a curvature adapted thereto.
  • the lateral walls of the second channels can be provided with additional openings for passing wires in order to allow to form connections with rafters or the like situated laterally of said channels.
  • separating walls etc. can be secured to such ceiling girders, which, in particular, can be provided with contact means for electric conductors, and fixing on a closing,lid or a part thereof is possible;
  • an additional clamping plate can be used therefor, which, by means of a screw connection, can be connected to a short closing lid section, said clamping plate being adapted to be inserted into two apertures in the lateral walls of a second channel, and to be fixed by tightening the screw connection.
  • auxiliary pieces can be used which, in the manner of the hangers, can be fixed in the curled edges of an upper channel, and for making a connection between mutually transversely directed girders coupling elements can be used which can be clamped in a terminal part of a girder, and are provided with a hook which can be hooked behind a curled edge of an upper channel of a girder directed transversely 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, eogo as a vernier hanger (as shown in the above-mentioned NL-A 80 02 016), 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 edgeso
  • 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 o 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 130
  • the channel 2 has a flat bottom 16 in which grooves 17 have been pressad, 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 at 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 parts28, 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 rods fitting 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.
  • a suffucient 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.
