Definitions

  • the invention relates to a gas and dust-tight ceiling cladding made of metal, consisting of a rigid support grid and cassettes arranged in the grid fields of the support grid, wherein the support grid is made up of continuous longitudinal struts and transverse struts connected to them, and each longitudinal strut and each cross strut in each Longitudinally extending and arranged on both sides at their lower end, substantially horizontally extending projections, on the top of which are arranged seals on which the cassettes lie sealingly.
  • an intermediate ceiling which has longitudinal and transverse struts which are suspended from node pieces. Since the struts are held at the junctions only by their own weight, these elements are not fixed. In addition, the longitudinal and transverse struts are only roll-formed profiles that are not torsionally rigid, so that the false ceiling can be twisted and the necessary gas tightness can no longer be guaranteed. Like the longitudinal and cross struts, the cassettes are only held by their own weight. This can have a particularly disadvantageous effect if excess pressure is used in the rooms suspended with this false ceiling, since the cassettes can be raised due to the lack of fixation. The same applies, for example, to sterile ceilings in laboratories if a vacuum is created in the ceiling cavity to extract dirt particles.
  • GB-A-2087451 describes a suspended ceiling in which cross members are fastened to the longitudinal members via a snap-in connection.
  • a locking lug is provided on the cross member and a corresponding recess is provided on the longitudinal member.
  • a very precise design of the catch and recess is required, as well as correspondingly precise and therefore complex assembly. If the locking lug is pressed too deep into the recess, the cross member is higher than the longitudinal member, so that there is no precisely defined position of the carrier in this blanket. In addition, the flush mounting of cassettes and support system is not guaranteed with this false ceiling.
  • the invention has for its object to provide a ceiling cladding of the type mentioned, which allows a stable, optically appealing and gas-tight cladding even with variable grid dimensions with simple construction and easy assembly and disassembly of the cassettes.
  • the object is achieved in that the lateral projections of the longitudinal struts and the cross struts or the longitudinal struts and cross struts themselves are each formed from box-shaped, torsionally rigid profiles.
  • the projections on the top have at least one upwardly extending web which runs along the respective projection.
  • the seals are between the web and the side wall of the struts or can also be accommodated between them in the case of a plurality of webs.
  • the cassettes of spring elements are pressed onto the webs, the spring elements being supported on the side walls of the struts.
  • the depth and contour of the cassettes are designed such that their closed bottom surfaces are arranged flush with the struts.
  • the ceiling covering according to the invention is characterized by a number of considerable advantages.
  • Another important advantage of the invention is that the weight of the cassettes does not rest directly on the seals, as is known from the prior art, but is carried by the webs, while the seals are only in contact with corresponding surfaces of the cassettes to create a gastight seal to guarantee. Damage to the seals is thus avoided.
  • the cassettes since the cassettes always rest completely on the respective webs, it is also ensured that the seals on the entire circumference of the cassettes are in engagement, so that a gas-tight seal is ensured. Furthermore, the seal is protected against damage even when the cassette is removed and is not visible, in particular when the cassette is inserted, so that the overall visual impression is not impaired. Finally, the cassettes are always held in their inserted position by the spring elements fixing them.
  • the seal can also have a rectangular cross section and be designed as a solid profile, it proving to be advantageous if the sealing material as a whole has sufficient elasticity.
  • the seal In order to connect the seal to the projection in a secure manner, it preferably has a flat contact surface which can be glued to the projection, for example.
  • This flat contact surface can be provided both in the case of a tubular seal and in the case of a rectangular seal.
  • the seal is preferably made of an elastic material with a closed surface manufactured, for example from a closed-cell foam or the like.
  • a further web can be arranged parallel to the web between the web and the wall of the longitudinal strut or the cross strut. This further web is used to form a U-shaped channel cross section, in which the seal is inserted.
  • This design measure prevents spring elements which are arranged on the longitudinal web and on the cross web from being able to damage the seal.
  • the cassette can prove to be advantageous for the cassette to have a circumferential step fold on its outer lower edge region, the cassette resting with the horizontal surface of the step fold on the projections or the webs.
  • the formation of the step fold makes it possible to arrange the lower surface of the cassette flush with the lower surfaces of the longitudinal struts and transverse struts.
  • the spring elements fixing the cassettes in their position on the longitudinal struts and / or on the cross struts are designed as leaf springs, the ends of these leaf springs being held in opposing grooves formed on the side walls of the longitudinal or cross struts.
  • the spring elements thus bring about a firm support of the cassettes on the webs of the projections, so that the cassettes lie exactly on the optical point of view and are pressed into contact with the seals with regard to the required sealing effect.
  • the springs have an angled section between the two ends, one leg of which extends essentially vertically, is resiliently supported on the side surface of the cassette and up to approximately runs at the level of the upper edge of the cassette, and its other leg runs above the upper edge of the cassette and is angled outwardly with respect to the side wall of the strut. It can furthermore prove to be advantageous if one leg is adjoined by a leg which preferably extends in a straight line towards the lower groove and on the other leg a leg which preferably extends in a straight line to the upper groove. Furthermore, a spring end section, which runs parallel to the side wall of the strut, can connect to the legs of the tongue that extend toward the grooves. All of these configurations improve the pressing of the cassettes against the webs and ensure an adequate seal.
  • the invention provides that the grid fields at the transition area to a wall are delimited by a wall connecting strut. This configuration gives the possibility of even irregular wall shapes in a sealing connection to the Bring ceiling paneling. It may also be favorable that the wall connection strip has a horizontal projection extending in its longitudinal direction, on the upper side of which a seal which can be brought into contact with the cassette is arranged. This configuration ensures that a gas-tight seal is also present in the transition area to the wall.
  • a second projection parallel to this is arranged above the first projection, below which a horizontal region of the cassette can be inserted. The cassette is thus guided and held in a U-shaped groove, thus moving the cassette or unintentionally loosening is excluded.
  • the seal has a U-shaped cross section and is mounted on the second projection and comprises at least one sealing lip pointing in the direction of the first projection.
  • the sealing lip is in contact with the horizontal area of the cassette and enables a gas-tight seal. Since the sealing lip extends into the U-shaped area between the first and the second projection, a sufficient pretensioning force of the seal is ensured at the same time.
  • the cassette is provided with internally mounted internals which can be designed, for example, in the form of a lamp or an air supply / air discharge device. This proves to be advantageous because no additional leakage points are possible due to additional internals or attachments.
  • the ceiling covering according to the invention consists essentially of horizontally arranged, mutually parallel longitudinal struts 2, of cross struts 4, which are arranged between the longitudinal struts 2 and are each fastened with their ends to the longitudinal struts, and of cassettes 6, of the longitudinal struts 2 and the cross struts 4 are worn.
  • the longitudinal struts 2 are above one another from the upper side 12 of the longitudinal struts 2 supporting straps 14 extending at the top are fastened to supports 8, which in turn are height-adjustable, for example by means of threaded rods 16, relative to the ceiling, not shown.
  • the support straps 14 of the longitudinal struts 2 are angled at their upper end, so that the longitudinal struts can be suspended from the supports 8 via the horizontally extending angle leg 18 of the support strap 14.
  • the support straps 14 are secured to the supports 8 by means of screws 20.
  • the longitudinal struts 2 and the cross struts 4 are designed as aluminum profiles.
  • the cassettes 6 carried by the longitudinal struts 2 and the cross struts 4 are made of electrolytically galvanized sheet steel, the visible sides of both the cassettes 6 and the longitudinal struts 2 and the cross struts 4 being coated with thermally hardened paint, for example in the color RAL 9010.
  • the shape of the longitudinal struts 2 can be seen in particular from FIG. 3.
  • the longitudinal struts 2 are designed essentially as a rectangular box section, the upper side 12 of the box section being largely open so that the inside of the box section is accessible.
  • Continuous, laterally projecting supports 26 are formed on the two longitudinal sides 22, 24 of the box section in the longitudinal direction of the longitudinal struts. These supports 26 are also designed in the manner of a box profile, the underside 28 of the supports 26 being in one plane with the underside 30 of the longitudinal strut 2 in the manner of a box profile.
  • Three vertical webs 34, 36, 38, which extend in the longitudinal direction of the longitudinal strut 2, are each formed on the upward-facing upper side 32 of each support 26, the outer web 34 extending the side wall 40 of the box-shaped support 26 represents, the web 38 is arranged near the longitudinal side 22 of the longitudinal strut 2 and with this defines a groove 42 and the web 36 is arranged between the web 34 and the web 38.
  • a sealing strip 44 is inserted, which can be made of rubber, for example, extends over the entire length of the longitudinal strut and, in the non-compressed state, projects slightly beyond the upper edges of the webs 34, 36.
  • a web 46 is formed, which runs parallel to the long sides and over the entire length of the long sides and defines a groove 48 between them and the adjacent side wall 22 or 24.
  • the opposing grooves 42, 48 serve to receive springs 50 to be described in more detail below.

  • the supports 56 have the same cross-section as the supports 26 of the longitudinal struts 2 and are therefore designed in the manner of a box profile with side walls 70 and upper sides 62, from which webs 64, 66, 68 extending in the longitudinal direction extend upwards, between the webs 64, 66 Sealing strips 74 are arranged, and wherein grooves 72 are formed between the webs 68 and the adjacent side surface of the strip 80.
  • longitudinally extending, downwardly pointing webs 76 are formed which define grooves 78 between themselves and the adjacent side faces of the strip 80.
  • the opposing grooves 72, 78 serve, as in the case of the longitudinal struts 2, for receiving the ends of springs 50.
  • a stiffening bar 60 running at right angles to the level of the bar 80 is formed along the upper edge of the cross bars 4.
  • the strip 80 has a thickening 82 extending approximately in the center in the longitudinal direction, in which a threaded bore 84 extending in the longitudinal direction of the cross strut 4 is formed in the center.

  • the width of the cross struts 4 can be approximately 4 cm and the height of the cross struts 4 corresponds the height of the longitudinal struts 2 and is thus 7.2 cm.
  • the screws 54 are guided from the inside of the longitudinal struts 2 through the through bores 52 of the longitudinal sides 22, 24 of the longitudinal struts 2 and screwed into the threaded bores 84 of the cross struts 4 opposite the through bores 52.

Afin d'obtenir un agencement des cassettes (6) qui satisfasse en même temps des critères esthétiques et d'étanchéité, les protubérances (26) présentent des barrettes verticales (34) sur lesquelles repose le bord à gradin (88) des cassettes (6). Des éléments d'étanchéité (44) sont en outre agencés sur les protubérances (26) et s'appuient contre les cassettes (6) à l'état monté. On obtient ainsi un agencement mécanique sûr par rapport aux cassettes (6) et une étanchéité suffisante des éléments d'étanchéité (44).
