An improved prefabricated scaffold frame may be employed to construct a numerous variety of scaffold structures. The scaffold frame comprises three tubular uprights 10, 11, 12 of equal height, and at least three bar means 18, 19, 20 attached to the uprights and spaced equidistant from one another. Each bar means may be formed from two tubes connected with a connector 22, this connector and two further connectors 23 are then welded onto the uprights in a horizontal axis. A ladder 25 located between uprights 10 and 11 may form an integral part of the bar means. <IMAGE> |
