A valley roof bracket is an adjustable V-shaped bracket having an upper cross-member upon which a triangular shaped platform may adjustably be positioned. The device may be secured to an angular side of a pitched roof.

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.

A prop-brace coupler has a first section configured to be selectively connected to a vertical prop member of a construction platform that includes a vertical spacing member and a diagonal bracing member. The prop-brace coupler also has a second section configured to be selectively connected to the vertical spacing member and to the diagonal bracing member.

Disclosed herein is a support base for use in shuttering formwork. The support base includes an angle section member and a plurality of clamping brackets. The clamping brackets further include clamping members engageable with the clamping brackets to define a clamping portion aligned with openings on the angle section member. Also disclosed herein is a method of supporting shuttering formwork which uses the support base.

A scaffolding assembly adapted to be releasably attached to an elongate support member such as an overhead pipe. The scaffolding assembly has a split collar and a platform assembly adapted to be releasably attached to the split collar. The split collar comprises at least two segments which can encircle the pipe and be secured to one another. The platform assembly which includes a platform deck has a connector formation which extends laterally outwardly from the deck to an extent that it can engage a receiving formation on the collar assembly and thereby attach the platform assembly to the collar assembly.

A catwalk system having a pair of side trusses formed of a top cord and bottom cord connected by a plurality of vertical posts and diagonal posts. The bottom cords have a plurality of joints formed of a bottom plate, opposing side plates and wing plates that form a pocket. These pockets receive an end of floorbeams which are bolted to the side plates. The bottom plate also includes a wind brace section that receives an end of a diagonal wind brace therein. The fabricated side trusses are shipped to the job site where the catwalk is quickly and easily assembled by aligning a pair of side trusses in parallel space alignment and installing floorbeams in the pockets of opposing joints. To provide additional rigidity diagonal wind braces are installed in a zig-zag formation between diagonally opposite joints. This arrangement provides a quickly assembled catwalk that requires minimal assembly.

A ladder seat assembly for assuming a seated position on a ladder includes a first bracket and a second bracket that are each positionable on a respective step of the ladder. A pole is coupled to and extends downwardly from the second bracket to engage the first bracket. A seat mount is positionable around the pole such that the seat mount is centrally positioned between the first bracket and the second bracket when each of the first bracket and the second bracket are positioned on the ladder. A seat unit is removably attachable to the seat mount wherein the seat unit is configured to have the user sit thereon while the user is on the ladder thereby enhancing comfort for the user.

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.
