Abstract
A beam member for use in a suspended ceiling system for retaining removable panel sections includes at each longitudinal end an integral tongue and a tongue-receiving recess for joining the beam member in end-to-end relationship with another beam member having an end of corresponding configuration. The tongue is characterized by inwardly diverging sidewalls, and an outwardly offset and a rearwardly extending detent. The detent has an edge defining a circular arc, and the recess includes an arcuate central portion for abutting the edge of the arcuate detent of another beam member when the beam members are joined and outwardly diverging sidewalls. Interlocked tongues of such configuration are capable of withstanding large tensile separating forces.
