Abstract: A preformed structural member that includes an elongated web having first and second flanges projecting laterally from its two longitudinal edges. Each of the flanges is of different construction, however, the flanges of two or more members can be interlocked to form either a right angle corner sections or continuous flooring or ceiling sections. Similarly, the member can be easily snapped into operative relationship with flat panels to create a self-standing sub-assembly possessing sufficient holding power to temporarily support the cojoined components until such time as they can be more securely locked together in final assembly.

Abstract: A structural member having similar flanges mounted on either end. The flanges of individual members can be interlocked to form either right angle sections or rectangular columns.

Abstract: A structural frame in which vertically aligned metallic studs are secured to horizontal metallic runners or the like by means of clips to create a strong, easy to erect, partition. Each clip includes two upraised legs that are connected at their upper ends by means of a sinusoidal shaped section. The lower end of each leg contains an outwardly extended locking key. In assembly, the sinusoidal section of the clip is received within a slotted hole formed in the stud with the bottom of the slotted hole being seated against one of the peaks of the sinusoidal waveform section. The clip is crimped to allow the keys to pass through a pair of receiving holes formed in the horizontal runner. The crimping force on the clip is released whereupon the locking bars are driven beneath the holes to lock the clip in place and thus secure the two structural members in assembly.
