Abstract (en)
[origin: US4729541A] There is disclosed a formwork for round or polygonal constructions with a formwork face having an adjustable curvature or circumference. The formwork has a chain of booms which are spaced apart from the formwork face and are composed of individual boom portions. The boom portions can be pivoted relative to one another and can be fixed in selected angular positions when the adjustment of the formwork face is completed. The pivot axes for the boom portions are not located at the boom portions themselves but are transposed into the plane of the formwork face so that the formwork and the formwork face are adjusted in assembled condition of the chain of booms. The boom portions, which are spaced apart from the joint axes have couplings which are adapted to be detachably connected to one another and are disposed along arcs with centers of curvature on the respective joint axes. The couplings can include overlapping plates with openings through which locking keys can be inserted.
