The bracket scaffold has an end-side first coupling element which is, in particular in a limited manner, pivotably arranged on a first carrier of the bracket scaffold. A rotation axis of the first coupling element preferably intersects with the support location of the first coupling element on the first securing element. The pivot radius of the first coupling element describes in particular a concave pivot arc on the first carrier. The rotation axis is located from the first guide preferably in the direction of the free end of the first coupling element. Extension torques in the articulation, which is formed by the first guide, are minimized by the bracket scaffold being pulled away from the structure. ## Claims ### Claim 1 A bracket scaffold for securing to a curved surface of a structure, the bracket scaffold comprising: a) a first carrier defining a first end opposite a second end;
