Claim:
A panel for a round form, comprising: a form skin; vertically extending profile rails on a backside of said form skin; a shaping bar extending transversely to said vertically extending profile rails and being curved along a longitudinal extent of said shaping bar, said shaping bar being detachably connected to said vertically extending profile rails and including at least two elements, each of said at least two elements being curved along the longitudinal extent of said shaping bar and extending over a large portion of the longitudinal extent of said shaping bar, and shoes for holding together said at least two elements of said shaping bar, each shoe comprising two clamping parts connected to one another via a tightening bolt, wherein said at least two elements of said shaping bar are positioned between said two clamping parts so as to be fixed relative to one another by said clamping parts when said tightening bolt is tightened, and wherein an offset between said at least two elements of said shaping bar in a longitudinal direction of said shaping bar at opposite front-side ends of said shaping bar is adjustable when said tightening bolts of all shoes which hold together the at least two elements of said shaping bar are loosened, wherein by said offset, which depends upon a curvature that the round form is to exhibit in the longitudinal direction of said shaping bar, at least one of said at least two elements defines a first end of said shaping bar in the longitudinal direction of said shaping bar and at least another of said at least two elements defines an opposite second end of said shaping bar in the longitudinal direction of said shaping bar.
