A closed vertical frame for constructing a supporting frame, including at least two vertical supports disposed at a horizontal distance from each other, and at least two horizontal arms disposed at a vertical distance from each other. Each extends between the at least two vertical supports transversely to the vertical supports. A first horizontal arm is welded on both ends to a respective vertical support near the upper end thereof, and a second horizontal arm is welded on both ends likewise to these vertical supports near the lower end thereof. The vertical frame is reinforced with at least one diagonal rod extending between two vertical supports and two horizontal arms and is welded onto two vertical supports. Near the respective upper and/or lower end, a perforated disk having openings is welded to connect holding devices. |
