Definitions

  • the invention relates to a gas and dust-tight metal ceiling covering, consisting of a support grid and cassettes arranged in the grid fields of the support grid, the support grid being constructed from continuous longitudinal struts and transverse struts connected to them, and each longitudinal strut and each cross strut in each case in the longitudinal direction thereof extending and arranged on both sides at the lower end of the, substantially horizontally extending projections, on the tops of which seals are arranged, on which the cassettes lie sealingly, and wherein the longitudinal struts are designed in the form of a substantially rectangular profile which has a cross-sectional section for attachment of suspension elements.
  • Gas- and dust-tight metal ceiling claddings are preferably used to seal rooms in the clinical area, in the laboratory area or clean rooms of manufacturing facilities in the ceiling area. Since these are often very large ceiling areas, it is necessary, on the one hand, that sufficient gas tightness is guaranteed, and on the other hand, the ceiling cladding must be able to meet high visual requirements.

  • Fixtures for example partitions, should only be installed over a certain period of time. During the subsequent dismantling, the holes that may remain in the longitudinal struts do not affect the tightness of the ceiling cladding. Since the longitudinal struts have sufficient strength, it is thus possible according to the invention to attach further attachments, also of greater weight, to these, for example lamps in the medical field, suspensions for laboratory devices or the like. Protrusions can advantageously be designed as conduit channels. In this embodiment, two conduit channels are thus available for each longitudinal strut, so that the application options for attachments are significantly increased.
