ABSTRACT:
A common structural member for use at several locations within a truck body is comprised of an elongated member having a uniform cross-section. The common structural member has a flat surface with stiffening ribs and a first pair of mutually parallel walls along its longitudinal edges. A longitudinal T-slot extends along a first one of the parallel walls, while a longitudinal first groove extends along the second one of the walls. A longitudinal notch or second groove is situated at the second wall, and one of the notch or grooves is arranged at right angles to the T-slot while the other of the notch or grooves is arranged parallel to the T-slot. Each of the notch and grooves is adapted to accept a sheet metal panel therein. The T-slot comprises an inset channel, a slot perpendicularly intersecting said channel, and a recess opposing the slot. The T-slot further comprises at least one enlarged aperture adapted to accept a bolt or a nut therethrough for insertion into the T-slot recessed channel. In another embodiment, the common member further comprises a second pair of mutually parallel walls joined perpendicularly to the first pair of mutually parallel walls, thereby forming four longitudinal edges. Either a T-slot or a groove is situated at each of the longitudinal edges, with each of the T-slot or grooves having a particular orientation, relative to each other, such that the common member can be used at several locations throughout a truck body.
