ABSTRACT:
A modular ceiling system utilizing a plurality of stringers interlocked with one another to provide a rectangularly celled, high strength, non-warping suspended ceiling grid assembly. The T-shaped extruded aluminum stringer employed in the grid assembly has a channel-shaped T-head designed to support acoustical ceiling tiles flush with the lower edge of the stringers. The main stringers are arranged parallel to one another and interlocked to secondary stringers to provide a grid of four sided cells. Part of the secondary stringers have the same length as one side of a single cell and others are of double that length. The double length secondary stringers are constructed to have a snug snap-lock joint with the main stringers whereas the single length secondary stringers have a snug, non-locking fit between the mid-portions of the double length stringers. A lighting unit occupies a pair of adjacent grid cells and is installable selectively with its length extending either lengthwise or transversely of the main stringers and includes provision for supplying and exhausting ventilating air. The downwardly opening channels of the T-head portions of all stringers serve multiple functions, including an anchorage for various suspended objects, room divider partitions, etc.
