Abstract:
1. A vertical scaffolding frame of metal comprising: a first vertical post having: a first apertured disc having several passages, arranged concentrically with respect to the first vertical post, surrounding the first vertical post to form a flange, and permanently fastened to the first vertical post, the first apertured disc being a sole apertured disc fastened to the first vertical post; a first railing element fastening device at the first vertical post at a spacing from the first apertured disc and being able to fasten a railing element serving as a safety device against falling; a second vertical post having: a second apertured disc having several passages, arranged concentrically with respect to the second vertical post, surrounding the second vertical post to form a flange, and permanently connected with the second vertical post, the second apertured disc being a sole apertured disc fastened to the second vertical post; wherein the first railing element fastening device is constructed differently from the first apertured disc and differently from the second apertured disc; wherein the first vertical post and the second vertical post are connected by one single rod-shaped horizontal transverse arm extending transversely away from both the first vertical post and the second vertical post, permanently connected to both the first vertical post and the second vertical post by welding to be stiff in bending and torsion, and forming one single crossbar having: wherein the first connecting head is plugged by a slot of the first connecting head, which is open towards the first vertical post and towards the vertical outer surfaces of the first connecting head, onto the first apertured disc such that the first apertured disc at least partly projects into the slot of the first connecting head and such that the wedge of the first connecting head is formed by the vertical outer surfaces of the side wall parts of the first connecting head running together towards a center of the first vertical post and towards a center of the first apertured disc; wherein the first connecting head is permanently connected with the first vertical post by welding; wherein the second connecting head is plugged by a slot of the second connecting head, which is open towards the second vertical post and towards the vertical outer surfaces of the second connecting head, onto the second apertured disc such that the second apertured disc at least partly projects into the slot of the second connecting head, and such that the wedge of the second connecting head is formed by the vertical outer surfaces of the side wall parts of the second connecting head running together towards a center of the second vertical post and towards a center of the second apertured disc; and wherein the second connecting head is permanently connected with the second vertical post by welding.
