Abstract: A platform erected by adding an other platform portion to an existing platform portion, as illustrated in FIGS. 20 to 23, by holding a first other truss adjacent decking of the existing portion, connecting ends of sides of the first other truss and a first existing truss with a first pin, swinging the first other truss about the first pin, and connecting ends of other sides of the first other truss and first existing truss with a second pin. In order to similarly connect a second other truss to a second existing truss, the first pin is removed and the first other truss is swung out of the way. After the second other truss is connected to the second existing truss, the first other truss is swung back into position and the first pin re-inserted. Decking is applied to the first and second other trusses.

Abstract: An erected platform which contains parallel lines of trusses connected end-to-end and method of erecting thereof, as illustrated in FIGS. 20 to 23. Each truss has two sides for chords respectively, with apertures or eyelets at the ends. First and second other trusses for a pair of parallel lines respectively are connected by positioning a first other truss adjacent the decking laid on an existing platform portion. Apertures on first respective sides of the first other truss and one of the existing trusses are connected by a first pin and the first other truss swung into an end-to-end position with the one existing truss and a second pin inserted in apertures on second respective sides of the first other truss and the one existing truss. The first pin is removed and the first other truss swung out of the way so that the second other truss may be attached. The second other truss is positioned adjacent the existing decking and similarly connected end-to-end with the other existing truss. The first other truss is then swung back into position for end-to-end attachment to the one existing truss and the second pin re-inserted.

Abstract: A platform and a kit therefor. The platform and the kit comprises quad-chord trusses attachable end-to-end and having connector members intermediate thereof, and further comprising beams attachable at their ends to the connector members so that a beam attaches two parallel trusses. A truss comprises first and second pairs of chords which are foldable for storage and transport and unfoldable to use for erection of the platform. A track lies between the upper chords to allow movement of bolts along the track into position to attach for insertion into decking apertures for attachment of the decking. The kit also includes a sturdy and reliable and easy to use tie-up mechanism and railing along the platform perimeter which is quickly and easily attachable and reliable.

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.

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.

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.
