Abstract: A kit for erecting a platform. The kit comprises a plurality of quad-chord trusses. Each truss is attachable to others of the truss by eyelets on the ends of the chords. When the chords are spaced horizontally, the eyelet apertures are vertical for receiving pins, which allows a single pin to be inserted in eyelet apertures on one side of the truss so that one truss is swingable horizontally into position for rigid attachment end-to-end by inserting another pin in eyelet apertures on the other side of the truss. Each truss comprises a plurality of connector members for attachment to the trusses along their lengths. The kit further comprises a plurality of cross beams having connector members at their ends to mate with and attach to the truss connector members, and a plurality of tie-up mechanisms attachable to the trusses and to which a supporting line from an overhead structure is attachable. The cross beams have overhangs at their ends for overhanging the upper ones of the chords to allow ease of movement along the chords and attachment. A track lies between the chords of each truss to allow movement of bolts along the track into position for insertion into decking apertures for attachment of the decking. The trusses may be foldable for transport and storage.

Abstract: A foldable quad-chord truss which can be connected end-to-end with like trusses. The chords of each pair of chords are rigidly attached, and connector members intermediate the ends are each swivelly attached to each of the chords of each chord pair to effect the folding into a compact shape for transport and storage. The connector members are adapted for attachment to beams or connector members thereof which beams may extend between a parallel pair of the trusses.

Abstract: A fastener which comprises a tubular member, a sleeve, a spring, a shank, and an elongate head. A lower end portion of the shank extends through the tubular member to threadedly engage a lower part. The elongate head rotates within a slot in the upper end of the shank between a first position extending longitudinally of the shank so that it can receive an upper part to be attached to the lower part and a second position extending radially of the shank to prevent removal of the upper part. The shank is received within the sleeve and has a pair of slots in its upper end which are alignable with the shank slot. The sleeve is biased to an upper position by the spring, which is in the tubular member. When the sleeve is in a position wherein it is biased upwardly, the sleeve partially covers the shank slot to prevent rotation of the elongate head between the first and second positions. The sleeve can be pushed downwardly against the force of the spring when the shank is sufficiently loosened to substantially uncover the shank slot thereby allowing rotation of the elongate head between the first and second positions.

Abstract: A foldable quad-chord truss which can be connected end-to-end with like trusses. Each pair of chords are rigidly attached, and connector members intermediate the ends are swivelly attached to the chord pairs to effect the folding into a compact shape for transport and storage. The connector members are adapted for attachment to connector members of beams which may extend perpendicular to a parallel pair of the trusses and attached thereto. The laid trusses and beams is overlaid with sheets of corrugated sheet metal which overlap each other along their adjacent edges. While standing on a sheet of laid sheet metal adjacent ends of an already laid pair of trusses, another truss can be held adjacent the edge of the sheet metal for attaching an end of the other truss along only one side so that it can then be swung outwardly into a position wherein the other end of the other truss can also be attached to rigidly connect the trusses end-to-end.
