ABSTRACT:
Building components are disclosed for constructing of frames, enclosures, and the like, comprising hollow edge struts all of uniform cross section, with the ends of each edge strut providing a female joint. Interlocking members are provided having a central member with a plurality of legs extending outwardly from the central member and at fixed angles to each other, the legs each defining a male member adapted to be inserted in said female joint. The legs have locking clip recesses formed therein in at least two adjacent surfaces of the legs, the locking clip recesses spanning substantially the entire width and length of the surfaces of the legs. An abuttment shoulder is formed at the central member and end of the locking clip recess which the edge strut butts up against when installed. Locking clips are provided having arms corresponding in number, and disposed within the locking clip recesses formed in the legs are inserted within the locking clip recesses before the edge struts are interlocked with the legs. The arms on each of the locking clips have a plurality of upstanding locking tabs formed therein to increase the strength of joints. The edge struts are cut to a specific length and interlock together by means of the interlocking members to form frames, enclosures, and the like.
