Formwork for surfaces varying in curvature has a face sheet adjustable with respect to its curvature, girders supporting the face sheet and applied to the girders, in spaced relationship to the face sheet, there is a boom system which is composed of individual boom members bridging the girders and is suitably attached to the girders at the outsides thereof averted from the face sheet. Adjustment of the curvature of the face sheet is carried out by altering the effective length of the boom members between the girders. The mutually opposed formwork elements are adapted to be braced together by means of formwork anchor ties. A crosspiece in the form of a boom member is applied to a formwork element at at least two girders and simultaneously serves as an abutment for the formwork anchor tie, the latter therefore being arranged between and having its reaction forces transferred to the two girders. The crosspiece is likewise changeable in its effective length by its fastening location being adjustable in the longitudinal direction in which the crosspiece extends and transversely to the orientation of the girder, so that the crosspiece is available as an adjustable boom member in altering the curvature of the face sheet, as well as sustaining the tension forces.
Formwork for surfaces varying in curvature, including a face sheet adjustable with respect to the curvature thereof, including girders supporting said face sheet and further including a boom system composed of individual boom members applied to the girders in spaced relationship to the face sheet, the effective length of the boom members between the girders and their points of application being adjustable at the girders to change the curvature of the face sheet (2), and mutually opposed formwork elements being adapted to be braced by means of formwork anchor ties, wherein a crosspiece in the form of a boom system member is applied to a formwork element at at least two girders and is simultaneously provided as an abutment for the formwork anchor tie, said crosspiece being adapted to be adjusted and located in position at at least one of the girders upon which said crosspiece acts, adjustment being effected in the longitudinal direction in which said crosspiece extends and transversely to the orientation of the girder, wherein the crosspiece is provided with an adjusting spindle with which a relative movement between the crosspiece and the girder upon which the crosspiece acts can be performed by means of a nut which is detachably fastened to the girder and cooperates with the spindle.
