Abstract:
1. A closed vertical frame intended for construction of a frame support, the closed vertical frame comprising the following features: (A) the closed vertical frame comprises at least two parallel vertical supports which are arranged at a horizontal spacing from one another and which each have an upper end and a lower end; (B) the closed vertical frame comprises at least two parallel horizontal arms which are arranged at a vertical spacing from one another and which each extend between the at least two vertical supports transversely to these vertical supports; (C) the closed vertical frame is stiffened by at least one diagonal bar which extends between two of the vertical supports and two of the horizontal arms and which is welded to two of the vertical supports or to two of the horizontal arms or to both one vertical support of the vertical supports and one horizontal arm of the horizontal arms; and (D) apertured discs, which are each provided with several passages, for connection of holding devices are permanently fastened by welding in the region of the respective upper end or in the region of the respective lower and upper end of at least two of the vertical supports, which apertured discs are arranged concentrically with respect to the respective vertical support and surround the respective vertical support as a flange; and either (E) a first horizontal arm of the horizontal arms comprises a horizontal strut having at each of its mutually remote ends a respective connecting head which is formed in single-part manner or multi-part manner with the horizontal strut, wherein the respective connecting head is bounded by side wall parts having vertical outer surfaces which taper towards the center and which include a wedge angle, and wherein the respective connecting head has an upper head part and a lower head part, which are integrally connected together and between which is provided a slot, which is open towards the associated vertical support and by way of which the respective connecting head is plugged onto an apertured disc, which protrudes at least partly thereinto, of the apertured discs, and wherein the connecting head respectively plugged onto the associated apertured disc is welded to a vertical support of the vertical supports in the region of the upper end thereof and also to the associated apertured disc, and wherein the vertical supports each have only a single apertured disc, which is respectively permanently fastened by welding in the region of the upper end of the respective vertical support and wherein a second horizontal arm of the horizontal arms is welded at both ends to a respective vertical support of the vertical supports in the region of the lower end thereof, or (F) a first horizontal arm of the horizontal arms and a second horizontal arm of the horizontal arms each comprise a horizontal strut having at each of the mutually remote ends thereof a respective connecting head formed in single-part manner or multi-part manner with the respective horizontal strut, and wherein the respective connecting head of the horizontal arms is bounded by side wall parts having vertical outer surfaces which taper together towards a center and which include a wedge angle, and wherein the respective connecting head of the horizontal arms has an upper head part and a lower head part, which are integrally connected together and between which is provided a slot, which is open towards the associated vertical support and by way of which the respective connecting head of the horizontal arms is plugged onto an apertured disc, which at least partly projects thereinto, of the apertured discs, and wherein the connecting head, which is respectively plugged onto the associated apertured disc, of the first horizontal arm is welded to a vertical support of the vertical supports in the region of the upper end thereof and also to the associated apertured disc, and wherein the connecting head, which is respectively plugged onto the associated apertured disc, of the second horizontal arm is welded to a vertical support of the vertical supports in the region of the lower end thereof and also to the associated apertured disc, and wherein the vertical supports each comprise only two of the apertured discs, of which in each instance a first apertured disc is permanently fastened by welding in the region of the upper end of the respective vertical support and of which in each instance a second apertured disc is permanently fastened by welding in the region of the lower end of the respective vertical support.
