Definitions

  • the present invention relates to the field of false ceilings, especially circulating suspended ceilings, particularly those that can be installed in specialized premises of the type clean rooms or local controlled atmosphere.
  • the invention relates more specifically to a circulable suspended ceiling device, as well as to a method of producing such a suspended ceiling.
  • Suspended ceilings or suspended ceilings intended to be used in the context referred to above must meet a certain number of criteria and constraints.
  • these suspended ceilings must constitute a substantially watertight barrier between the interior volume of the room and the volume located above said suspended ceiling (generally referred to as plenum) and provide a substantially flat and smooth surface at its face facing towards the ceiling. inside the premises.
  • interventions at suspended ceilings of the aforementioned type are made from above, accessing from the outside in the volume formed by the plenum.
  • interventions may consist of maintenance or replacement operations in terms of equipment, appliances, ducts or similar technical accessories mounted in the suspended ceiling, passing through the ceiling or located in the plenum, as components of the suspended ceiling itself. .
  • interventions may also consist of installation work of new equipment, devices or the like at the level of said suspended ceiling or in the plenum, possibly with replacement of certain portions or parts of said ceiling.
  • Such a suspended ceiling must therefore also allow a circulation in the plenum of at least one member of the technical staff, possibly carrying a load (tools, appliances, replacement component), without this entailing an alteration of its cohesion, nor of its performances.
  • such a suspended ceiling should also have a modular structure allowing a relatively easy replacement of one or a limited number of its constituent elements or components.
  • This circulable suspended ceiling defines a face directed towards the interior of the room and an opposite face that can be moved. Essentially, it consists of rectangular panels juxtaposed with butts and mounted suspended from an upper slab or a skeleton of the structure of the building concerned and, secondly, by means of localized suspension in the form of pre-assembled or pre-assembled sets forming lines, and engaging at reinforced longitudinal edges of said panels.
  • Each line is composed of two structural subassemblies assembled together, namely a first subassembly for fixing to the slab or the frame and a second subassembly for fastening the panels, each line coming into engagement with two adjacent panels which it ensures a localized suspension.
  • This known suspended ceiling structure provides a flat, smooth and practically continuous inner surface with the exception of small interstices between panels, which are easily clogged.
  • suspension and attachment means used in this known construction have a complex constitution and necessarily require the prior establishment of suspension rails attached to the slab or the metal frame.
  • suspension means must be assembled with the panels before their attachment and the assembly is therefore carried out in a single block.
  • the present invention aims precisely to overcome the limitations of the known solution mentioned above and to provide an improved solution, simpler, more economical and easier to implement.
  • a circulable suspended ceiling device especially for clean rooms, defining a directed face towards the interior of the room and an opposite, circulable face, essentially constituted, on the one hand, by panels of rectangular shape, juxtaposed with abutment and mounted suspended from an upper slab or a skeleton of the frame and, on the other hand, by means of localized suspension means in the form of pre-assembled or pre-assembled assemblies forming suspensions, and engaging by at least at the level of reinforced longitudinal edges of said panels, each suspension being composed of two structural subassemblies assembled between they, namely a first subassembly for fixing to the slab or the frame and a second subassembly of attachment of the panels, each hanger engaging with two adjacent panels which it ensures a localized suspension, characterized that the attachment subassembly consists of two cooperating profiled parts each having a substantially S-shaped section, assembled together mutually opposite each other so that their hook-shaped upper end portions overlap at least partially at their respective hooking

  • Each hanger 4 is composed of two structural subassemblies assembled together, namely a first subassembly 5 fixing to the slab 3 or the 3' frame and a second subset 6 hanging panels 2, each hanger 4 engaging two adjacent panels 2 which it ensures a localized suspension.
  • the attachment subassembly 6 is constituted by two cooperating profiled pieces 7 and 7 'each having a substantially S-shaped section, assembled together in mutually opposite arrangement so that their portions hook-shaped upper end 8, 8 'overlap at least partially at their respective hooking regions with the first subassembly 5 and that their hook-shaped lower end portions 9, 9' extend laterally mutually diverging, the two cooperating profiled parts 7 and 7 'being in intimate surface contact at least near their respective lower end portions 9 and 9' and in that at least the longitudinal edges 2 ' panels 2 are provided with or formed by C-section profile portions intended to engage in the lower hooks 9 and 9 'and abut against the pores. 11 and 11 'in intimate contact pairs of profiled parts 7 and 7' together constituting each attachment subassembly 6.

  • the mutually overlapping upper end portions 8 and 8 'being tight to each other, furthermore, the S-section shaped sections 7 and 7', as well as the C-section portions 10, are advantageously made of folded steel sheet, preferentially galvanized.
  • the latter may further comprise connecting plates 17 interconnecting at least two, where appropriate four, panels 2 at their adjacent corners, this on the upper moveable face 1 'of the suspended ceiling 1 ( figures 1 , 2 and 7E ).
  • the fastening of these plates 17 with the panels 2 is advantageously effected by means of fastening elements of the screw type, engaging with the frames of the panels 2 formed by the sections 10 and 10 ".
  • the plates 2 may comprise a day or a central orifice allowing a positioning control of said plates 17 relative to the panel 2, and the corner assembly of the latter.
  • the panels 2 have a composite constitution with two opposing outer facings 18 and 18 'intended to form the two opposite faces 1' and 1 "of the ceiling, a plate internal filler material 19 with thermal insulation property and / or phonic, preferably self-supporting and showing fireproof properties, and portions 10 and 10 "of C-profile, open on the outside, forming a peripheral frame.
  • the various components 18, 18 ', 19, 10 and 10 "constituting are advantageously assembled together by structural bonding resulting in a one-piece constitution and the length of the panels 2 is preferentially substantially an integer multiple of their width, for example twice that of the latter.
