ABSTRACT:
A suspended ceiling system for a clean room employing short cross runners connected to longer main runners. The connections serve to coax the cross runners against the main runners to keep the system intact and air tight. The grid of cross and main runners creates rectangular areas between them into which ledges extend from both runners. For a dry seal, a sealing gasket adheres to the ledges' upper surface. Ceiling components such as lights, filters, and tiles sit upon the gasket to provide the seal. For a wet seal, a trough sits upon the ledge and circumscribes each rectangular area. The trough contains a liquid material into which a knife edge depending from the ceiling fixtures sits. A continuous threaded slot runs along the center of the members' bottoms. This allows the attachment of accessories such as removable walls. The runners have a generally U-shaped cross section that gives it sufficient strength to bear the live weight of a person. Between the upright arms, the member have sufficient space to hold a room sprinkler and electrical conduit and piping.
