ABSTRACT:
Modular frame assemblies are made up of longitudinal beam members which may be angle or channel-shaped members having slots which intersect the flanges and legs or flanges and web portions of the longitudinal beam members. Transverse beam members extend between the longitudinal beam members and have flange portions which extend into the slots. The transverse beam members may be secured to the longitudinal beam members by conventional mechanical bolt assemblies, for example. In one embodiment, the slots in the longitudinal beam members have inwardly tapering surfaces which effect elastic deflection of the flanges of the transverse beam members to precisely locate the longitudinal beam members relative to each other and to the transverse beam members. In another embodiment, the slots in the longitudinal beam members are somewhat L-shaped and permit extension of the flange of the transverse beam member into a position to engage a flange of the longitudinal beam members, respectively, to be secured to each other by mechanical fasteners and to be located relative to the longitudinal beam members by opposed transverse surfaces on the transverse beam members. Another embodiment includes transverse channel shaped beams which have opposed distal web portions secured to the longitudinal beams and transverse edges of the channel shaped beams abut the legs or webs of the longitudinal beams.
