In the case of round shutterings, there is the problem of the setting to a specific diameter of the structure to be erected. As a rule, the shutterings comprise two or more shuttering supports (1) which run in the longitudinal direction of the shuttering skin (7) and are pre-bent corresponding to the curvature of the wall to be produced. In order to be able to set these shuttering supports (1) to an exact curvature radius, which does not change even during assembly work, the shuttering supports are formed from at least in each case two profiled rails (4, 5) which are supported on one another by their curved surfaces and can be fixed in a frictionally locking manner with respect to one another by a plurality of clamping elements (6) which follow one after the other in the longitudinal direction of the shuttering support (1). The shuttering supports (1) can be connected to one another in the longitudinal direction by flanges (13) arranged at the ends of said shuttering supports (1). <IMAGE> |
