Abstract
A T-frame member for a drop ceiling, made of rolled sheet metal, in which a web section is joined to a pair of coplanar flange members by a connecting channel section, the flange sections being joined to and extending outwardly from the respective outer edges of the two channel side walls. The inner edges of the flanges form lips projecting toward each other between the side walls. Partition studs having a collar slightly larger than the space between the lips are snapped into the channel sections and are retained by the collar, the studs projecting out through the space between the lips. Clips lock the flanges together after the studs are in place.
Claims3
A rolled sheet metal longitudinal T-frame member for a drop ceiling to support ceiling tiles or the like comprising:
- a web section formed of two sheet metal layers joined along a longitudinal edge, a channel section having two parallel side walls joined by a transverse wall, the sheet metal layers of web section being joined along a longitudinal edge to the side walls of the channel section by respective sheet metal sections forming the transverse wall, the side walls of the channel section extending parallel to and away from the web section, a pair of flange sections lying in a common plane extending perpendicular to the plane of the web section, each flange section being formed of two layers of sheet metal joined along the outer edge of the flange section, one layer of each flange section being joined along one longitudinal edge to the outer edge of a respective one of the side walls of the channel section, the flange sections projecting outwardly away from the respective side walls and forming a flat supporting surface on either side of the channel section for supporting ceiling tiles, the other layer of each of the flange sections including a lip extending into the space between the parallel side walls of the channel section, each lip terminating in an edge extending inwardly toward the transverse wall of the channel, the lips having a gap between the inwardly extending edges.
