Ceiling module for clean room

Abstract

Abstract There are at least two joists in the structure, each of them comprising two superimposed rails, (2,4) between which are fitted vertical side and gable plates (6) for the module. The module has coupling components (8) for assembly to adjacent modules to form a composite ceiling of required size. The under rails of the joists are formed to support in a sealed manner an air filter, ceiling plates or lighting fixture with hollow spaces or channels limited by the side and gable plates and a plate (14), covering the top side. These spaces or channels are for air distribution. The side and gable plates (6) are formed with input and output air apertures (10) to connected the hollow spaces or channels in assembled modules with each other. The coupling components (8) between adjacent modules are screw unions or snap locks and a rubber packing ring is fitted around each module, pref. on the joist upper rail (2).
