Abstract
A support structure for moveably suspending a work surface from the underside of a bridge includes at least a first clip mounted on each lower web of a pair of parallel bridge girders, a track mounted on each clip, and a scaffold member rollably suspended from the track, the work platform extending between the scaffold members. The scaffold members include a plurality of rollers that roll along the upper surface of each track such that the scaffold members are selectively rollable along the tracks. The clips are securely clamped to the lower webs of the girders such that the rails are securely and unadjustably spaced below the lower webs of the girders.
Claims26
A support assembly for movably suspending a work platform from a structural member, said support assembly comprising:
- first, second and third L-shaped clips adapted to be mounted on the structural member;
- and
- an elongated track mounted on said first, second and third clips;
- wherein said elongated track comprises at least a first and a second elongated track section, and said first and second elongated track sections each have a first and second alignment feature, and the first L-shaped clip has at least one alignment feature which is engaged by the first alignment feature on the first elongated track section;
- the second L-shaped clip has a first alignment feature and second alignment feature, wherein the first alignment feature of the second L-shaped clip is engaged by the second alignment feature of the first elongated track section, and the second alignment feature of the second L-shaped clip is engaged by the first alignment feature of the second elongated track section;
- and the third L-shaped clip has at least one alignment feature which is engaged by the second alignment feature of the second elongated track section, whereby the first and second elongated track sections are positioned in longitudinal alignment, and said L-shaped clip alignment features each comprise a first retention structure disposed on said L-shaped clips, and said elongated track section alignment features each comprise a retention structure being selectively engageable with a respective one of said first retention structures.
