A shuttering for producing frustoconical and pyramid-shaped walls, in particular of concrete, uses a plurality of circular or polygonal crossmembers (11, 12, 13) of different diameter. Load-bearing members (14) are, distributed over the outer surface, connected to the concentrically arranged and spaced-apart crossmembers via connecting elements (15) which can be adjusted along the load-bearing members. <IMAGE>
