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 supporting framework having at least one suspension device for a diagonal cross brace that reinforces the supporting framework, wherein the suspension device has receiving fingers for openings provided on the ends of the diagonal cross brace, characterized in that two first receiving fingers of the suspension device each have a bent end portion, and second receiving fingers situated opposite from the first receiving fingers have a pivotable end portion.
