Abstract
A suspended ceiling system for use in a cleanroom or other application incorporates a framework formed from lengthwise and crosswise frame members which form open areas for mounting components such as air filter modules, light fixture panels, blank panels and the like. The ceiling system includes splice members for connecting the frame members together and clamps for securing the components to the frame members. Suspension members, which preferably engage corresponding fastening members disposed within the frame members, suspend the framework from the ceiling, defining an interior space above the framework. Substantial loads, such as utilities, robotics and wall partitions may be suspended from the framework by clips that engage with the frame members.
Claims14
A suspended ceiling system comprising:
- a plurality of frame members arranged to form a load-bearing framework, each of said members having a cross-section comprising a solid vertical portion and a solid horizontal portion in an inverted T-shape, the upper end of said vertical portion including a slot whose sides are threaded and which extends along the length of the member;
- a plurality of threaded rods for suspending the framework from a structure;
- and
- cross dowel nuts disposed in said vertical portions, oriented transverse to the lengths of the frame members and extending through walls defining the slots, said rods extending vertically through said slots and threadedly engaging said cross dowel nuts.
