Definitions

  • the invention is based on a suspended ceiling with a suspended supporting frame according to the preamble of claim 1.
  • a known suspended ceiling of this type (DE-U-87 09 026), which is used in particular for clean rooms, laboratories, medical rooms and the like. is suitable, comprises a one-piece support profile, which is assembled to form longitudinal and transverse rails at intersection points in the joint.
  • the one-piece support profile itself consists of two box section parts which are open upwards and downwards in the direction of the longitudinal axis and a central box section which connects the two box section parts, wherein reinforcing ribs can still be arranged at any point.
  • connecting elements are provided in various embodiments, which can be hooked in, for example, by means of dovetail guides, or are designed in a general T-shape so that a middle retaining web is inserted into the closed box profile of each mounting rail and the base webs extending from the retaining web on both sides at an angle of 90 ° can also be screwed to the main profile.
  • the main profile due solely to the upper and lower open box section parts, necessarily has laterally projecting webs, which, for example in the lower open box section, serve to hang an essentially U-shaped cover section, which can then be fitted inside Lines and the like records.
  • These laterally protruding webs or projections which extend over the entire length of each support profile, naturally prevent a transversely attached further support profile in the region of intersection points from being brought up to the middle box section part or at all in abutment from the support profile forming the longitudinal rail .
  • the cassettes are held by resilient tensioning elements, namely leaf springs, the ends of which are held in opposing grooves formed on the side walls of the longitudinal and transverse rails. Starting from these grooves, the leaf springs then run outward at an acute angle, so that a constantly resilient pressing pressure has an effect on the inserted cassettes.
  • connection elements it is known for a suspended ceiling with a suspended support structure (DE-U-19 95 158), connecting elements to be provided, the ends of which are inserted into two mutually aligned transverse support rails and which overlap the longitudinal support rails crossing the two transverse support rails with a central section.
  • a mutual bracing of the support rails forming the support frame is not possible with these connection elements, so that the longitudinal and transverse support rails can rotate against each other, which occurs, for example, when the individual frame fields are loaded unequally.
  • Another false ceiling of this type uses the same, inverted T-shaped profile for the longitudinal and transverse support rails, consisting of a vertical web and horizontally extending flanges attached to the bottom on both sides.
  • the solid, vertical web has thickenings of different heights, a first thickening in the transition area to the horizontal base flanges containing a laterally open longitudinal groove, while a thickening at the distal end of the vertical web has an open top Has longitudinal groove.
  • These longitudinal grooves are used to hold thread webs, at least what the Upper, upwardly open longitudinal groove at the end of the vertical web relates, the threaded rod extending through a groove running transversely thereto, for example a longitudinal support rail through a transverse bore additionally provided there, and being screwed on both sides with the aid of nuts in the cross support rails.
  • slots accessible from above must be provided in the upper thickening of each of the cross support rails.
  • dowel pins or notch pins are inserted into the lower longitudinal channels located there, so that the longitudinal and transverse support rails are secured against relative rotation.
  • the support profiles are suspended with the help of additional suspension brackets, which have an almost closed U-shape and which engage in transverse grooves in the longitudinal grooves on both sides of the support profile, with two suspension brackets holding a metal column from both sides, into which a threaded support rod is attached by means of a thread is screwed, which in turn is attached to the bare ceiling.
  • the transverse support rails require a separate refurbishment and preparation in order to achieve a continuously flush underside of the supporting frame and to produce a sealing support surface for the cassette which is continuously guided around the frame structure.
  • the horizontal flanges must be cut off at the ends of the transverse support rails over such a length that the vertical web in each case can also rest with its end face on the side of the vertical web of a support rail running perpendicularly to it. It is difficult to carry out this work precisely in the assembly area, unless you determine from the start which of the profile rails are longitudinal support rails and which cross support rails are, which in turn complicates storage and transport.
  • longitudinal and transverse support rails having an internal cavity and having a general shelf-board-like shape, i.e. without the T-shape with a correspondingly high strength, are provided, which thereby be connected to each other can that connecting elements of any shape are provided, but with pin-like projections.
  • the projections are inserted into the cavities of the individual flat longitudinal and transverse support rails to be connected to one another, up to a stop which results in the transition between the insertion pin and the main body of the connecting element.
  • the connecting elements cannot have a T-shape either, at least not in their basic shape used to fasten the individual mounting rails to one another.
  • the arrangement of a large number of pegs on a connecting element may result in any T-shape due to the peg configuration, but these have no relation to the T-shaped connecting elements in the present invention.
  • the invention has for its object to provide a suspended ceiling with a suspended, intersecting support structure that is simple to build and easy to assemble with a dense and walkable design and with no additional processing of the rails, depending on whether it is longitudinal or cross support rails, needs to be made, but on the other hand an all-round fixed bracing is possible.
  • the false ceiling according to the invention solves this problem with the characterizing features of the main claim and has the advantage that twisting of longitudinal or transverse support rails relative to one another is excluded from the outset by means of a separate connecting element of T-shaped configuration approximately in the order of magnitude of the profile rail are, by inserting the middle retaining web of the connecting element into the hollow longitudinal space of a first support rail to be connected in the joint with a distance-free transition with torsion and canting-free attachment is achieved; the two base webs of the T-connection profile or at least one of the base webs serve or are then used for attachment to the vertical main web of the support rail running transversely thereto, for example by screw connections, the web connection being able to be secured by a cross bolt.
  • the height of the separate connecting element is dimensioned such that it with its central retaining web and its base webs on both sides between the stop surfaces of the general support profile fits - in other words, the formation of milled portions or crankings, which is always necessary, in order to connect one T-profile in the joint with another, is taken over by the special dimensions of the separate connecting element.
  • the double-walled design of the vertical main web of the profile rail gives it a particularly high strength, and it is also possible to screw connecting means, for example screws, into the profile rail from below, since the main web area is kept wide enough. It is therefore possible to place other items of furniture such as lamps, fans and the like at any given location. hanging from the false ceiling.
  • a particular advantage of the present invention is that the (bilateral) base webs of each separate connecting element can be screwed to the vertical main web of a transversely guided profile rail, preferably at predetermined points, both at the top and at the bottom (as seen in terms of their height), so that here Appropriate threaded holes can be prepared in the factory, including appropriate holes on the base bars.
  • Through these screw connections it is possible to firmly pull and clamp each transverse support rail, in the hollow longitudinal space of the vertical main web, the retaining web of a connecting element and fastened, preferably bolted, by screws to the corresponding longitudinal support rail (or vice versa), so that the tightness underneath is maintained in all circumstances, even when walking on the suspended ceiling from above, i.e. when pressure is exerted on the suspended ceiling from this side.
  • the fittings use the connecting elements and their bolts in the corresponding transverse rails to ensure that the ceiling cannot open downwards.
  • the basic profile of the mounting rail is designated by 10; the general basic shape of the support profile is such that the vertical main web 11 forms an inner cavity 12 of, for example, a rectangular cross section, that is to say it consists of two walls or partial webs 11a, 11b running parallel to one another.
  • This simple basic shape of the support profile is completed by support legs 13a, 13b attached on both sides to the vertical main web 11 at the bottom (in the plane of the drawing and also in the preferred position of use), while the vertical main web 11 merges upwards into a rectangular hollow profile 14 which is open at the top.
  • This hollow profile 14 is formed in that the two parallel partial webs 11a, 11b are covered at the top by a horizontal end plate 15, which is wider than the vertical main web, whereby the hollow longitudinal space 12 is also completed. Legs 15a, 15b extend vertically upward from the end plate 15, which again have inwardly directed shorter projections 16a, 16b.
  • This basic form of a support profile for longitudinal or transverse support rails is adapted to the corner connection shown in FIG. 2, which is generally referred to as connecting element 21.
  • the connecting element 21 is also of a basic T-shape with a central retaining web 22 and two lateral base webs 23a, 23b. Starting from the base webs 23a, 23b on both sides, the middle holding web 22 has a thickened rectangular shape 22a, which is at a predetermined distance from the base webs via a Shoulder or a stop 24 passes into the narrower shape 22b of the retaining web.
  • the thickness of the narrower part 22b corresponds approximately to the width of the inner hollow longitudinal space of the support profile, while the height of the shoulder 24 above the lower surface of the base webs corresponds approximately to the distance A of the end of each lateral support leg 13a, 13b from the vertical main web 11.
  • the T-profile of the corner connection according to FIG. 2 can be produced in that a corresponding T-profile, as shown in the top view in FIG. 2, is usually produced, for example by continuous casting, and then corresponding sections are also cut to size, the height of each connecting element 21 thus obtained essentially corresponding to the spacing between the stub-like profile projections 18a, 19a, 18b, 19b, but also 20a, 20b.
  • the connecting element 21 is fastened, preferably by introducing a transverse bolt 27 into mutually aligned and usefully provided bores through the two part walls 11a, 11b and the narrower part 22b of the holding web. Since the thickening 22a is practically as wide as the vertical main web, this continues through the introduction of the corner connection or the connecting element until the two base webs 23a, 23b of the connecting element lie flat against the facing outer surface of one partial wall of the vertical main web 11 1 in the illustration of FIG. 1 on the outer wall of the partial web 11b.
  • base webs 23a 23b then need to be connected at a predetermined point, for example at 28 and preferably above and below, to the corresponding partial wall of the vertical main web, preferably by screwing, but other types of connection are also possible here, for example with the help of hollow rivets or the like
  • connection point 25 is pressed firmly and, if desired, also gas-tight and a false ceiling made in this way cannot open even when walking on it.
  • leaf spring clips 29 with a corresponding profile, to snap in cassettes of any shape, indicated only, between the respective longitudinal and transverse support rails and to hold them in place by clamping.
  • first leaf spring clips 29 are clipped into the double U-shaped outer cavity on each side of the vertical main web 11 at a predetermined position; this outer cavity is formed by the outer surface of each partial web 11a, 11b in connection with the short profile webs 18a, 19a and 18b, 19b, which extend parallel to it at a distance.
  • a leaf spring clip 29 of the shape shown in FIG. 4 can be securely and immovably clipped in by first gripping the leaf spring clip with suitable pliers and in the direction of the two Arrows B, B 'squeeze until the vertical legs 31 the projecting short Reach behind profile webs 18b ', 19b'.
  • the clip is then firmly seated, but is elastically deformable and movable in the area of its double-sided, approximately triangular tip 32, this tip initially merging on both sides opposite into two vertical short spring pieces 33, to which legs 34 are bent at an acute angle which then continue, again at an acute angle, to the vertical legs 31, which then bend horizontally again into short lugs 35.
  • Such a leaf spring design makes it possible to insert the leaf springs in advance into the outer profile of the vertical main web and then simply lower a cassette 30 from above until it initially rests on an upper inclined surface of the tip 32; a strong jerk downward then allows this tip 32 to retreat, and the respective cassette 30 snaps down and the outwardly emerging tip 32 then secures the cassette 30 from all sides within the square or rectangular shape between the longitudinal and transverse support rails. Seals 36 can be placed in the support area on the support legs.
  • the leaf spring clips on both sides can also be formed in one piece, extending over the entire outer surface of the vertical main web, also at the top.
  • the retaining nuts 17 may be dispensed with if the threaded support rods directly into a threaded passage opening 37 of this with a sufficiently strong spring material Combination leaf spring clip can be screwed in.
  • Fig. 3 shows that the outer profile design of the vertical main web 11 can not only accommodate and secure corresponding leaf spring clips, as shown in Fig. 4, but also other holding inserts 38, for example made of a suitable metallic or plastic material, which are inserted laterally from the front can and then sit flush in the double U profile.
  • Such an embodiment with the inverted basic shape of the carrier profile proves to be particularly advantageous where, for example, filters (as intermediate or partial replacement elements for the cassettes) can only be used from below under certain circumstances.
  • the holding inserts have a projection 38 'with a thread, through which a pressure screw 39 can be screwed from below, which presses a (gutter-like) holding frame for a filter, indicated at 40, against one of the legs 13a "which are now located on the top.
  • a liquid seal namely a so-called liquid seal, such as petroleum jelly
  • a dry seal such as a rubber cord or the like
  • Connection to corresponding transverse support profiles can take place as explained above, although a separate holding rail 44 is to be provided for fastening to the bare ceiling, which holds a nut 45 with the usual double U-shaped profile open cavity profile 14 can be covered by a suitable insert 46.
