ABSTRACT:
A quick-set button or clip formed of a strip of spring metal has the general shape of the Greek letter omega, and joins halves of a two-part sheet metal beam or joist. The clip has an insertion bight formed at one end of a main elongated portion, and a Vee spring arm at the other end. The insertion bight has an offset portion, an outward leg and a return leg, and a diagonal portion that extends to a stub located at the underside of the main portion. The insertion bight and the Vee spring arm are inserted into corresponding aligned slots in the sheet metal web of the beam or joist, and spring action of the quick set button or clip holds the clip and the joist or beam forming members securely together.
