ABSTRACT:
A guard rail scaffold assembly comprises a plurality of assembly members carrying horizontally extending guard rails. Each assembly member comprises an elongated base member attachable by a releasable connector to a fastener pad fastened to an above-ground structure surface. The connector allows pivoting movement of the base member for adjustment of the base member to be parallel to the surface. The base member also carries surface engaging members on opposite sides of the connector which engage the structure surface to maintain the base member parallel to the structure surface. A first post member extends from the base member and, when the scaffold is mounted on the guarded surface, this constitutes a guard rail support member or has a guard rail support member mounted thereon. When the scaffold is mounted on a wall surface a second post member is releasibly mounted on the first post member and receives the guard rail support member instead of the first post member. The assembly can thus be fastened either to a horizontal or a vertical surface, or both, although each assembly member is fastened either to a horizontal or to a vertical surface, but not both. Forces applied to the guard rails are converted by the guard rail support members to force moments at one or other of the surface engaging members urging the base member to rotate about these areas, so that tension forces applied to the fastener pads are maximized and peeling forces are minimized.
