PCT No. PCT/EP87/00309 Sec. 371 Date Feb. 17, 1988 Sec. 102(e) Date Feb. 17, 1988 PCT Filed Jun. 12, 1987 PCT Pub. No. WO87/07922 PCT Pub. Date Dec. 30, 1987.A form for erecting structures having an plan shape, any generatrix and possibly changing wall thickness includes an inner form (1) and an outer form (2). Circumferentially closed support rings (5,6) are arranged horizontally spaced from the inner form as well as from the outer form. Radially aligned sleeves (35) are provided in the support rings (5,6). Threaded spindles (7,8) are slidably but fixedly held in the sleeves (35). One end of each threaded spindle (7,8) engages form carriers (11,12) which rest against the form carriers (3,4). The inclination of the form plates (3,4) or the wall thickness of the structure to be erected can thus be adjusted. Web members (13,14) are provided between the form plates (3,4) in circumferential direction of the form, the web members engaging over the form plate edges at the rear sides thereof. The web members have a support (15,16) on the surface facing the structure in the region between the side edges of the spaced-apart form plates (3,4). The thickness of the support (15,16) corresponds approximately to the thickness of the form plates (3,4).
