摘要： A platform and method for configuring and erecting a platform of support beams to which decking is applied so that it is suspended from and disposed below a main cable of a bridge. In one embodiment, a plurality of main cable clamps are spaced along and grippingly attached to the main cable. A pair of elongate members are each attached at one end to a respective one of the main cable clamps and at an other end to the respective support beam. In another embodiment, spaced slings are applied to the main cable so that each extends around the main cable. Ends of each of the slings are attached to a respective one of the support beams respectively. One end of a cable is attached to a sling intermediate ends thereof. The cable is extended between the sling and an anchor point and substantially parallel to the main cable there along to restrain the sling from slippage along the length of the main cable.

摘要： 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.

摘要： 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.

摘要： A temporary shield erected between two flanged structural members of a bridge or other structure, and a method for erection of the shield. A plurality of length-adjustable beams have end portions which are rested on flanges respectively of the structural members in a manner so that they are not fixed thereto. Decking is attached to the beams. At least one elongate member is cantileverly extended from at least one of the beams to underlie a structural member flange to prevent wind lift-up of the shield. A shield is also erected by adjusting the lengths of and hanging the end portions of each of a multitude of beams from the structure with the beams lying side-by-side. Decking is attached to the beams.

摘要： An adjustable suspension assembly for suspending a lower structure such as a platform from an upper structure such as a portion of a bridge. A sling, which is attachable at one end to the upper structure, is attached at its other end to one end of a chain. A device, which is attachable to the lower structure, has a pair of aligned apertures in its side walls for receiving pins. The pins are spaced to receive a thickness of a chain link but not to receive a width of the link, whereby a selected link to achieve a desired lower structure height may be cinched between the pins. The other end of the sling, which comprises a cable, has an eyelet formed by folding an end portion of the cable back over the cable and swaging the cable end portion to the cable. The chain is attached to said eyelet by receiving the end portion of the cable in one of the chain links before the cable end portion is swaged to the cable.

摘要： A platform disposed below at least one bridge main cable and method of erection thereof. The platform comprises a plurality of elongate decking support beams extending cross-wise of and disposed below the main cable and decking applied thereto. In accordance with one embodiment, a plurality of slings are spaced longitudinally of the main cable, and each extends around the main cable and is attached at its ends to a respective one of the support beams. A guy is attached to at least one of the slings for restraining the sling from slippage along the length of the main cable. In accordance with another embodiment, a plurality of main cable clamps are grippingly attached to the main cable and are spaced longitudinally of the main cable. At least one pair of elongate members sre each attached at one end to a respective one of the main cable clamps and at an other end to the respective support beam.

摘要： 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.
