Abstract
An adjustable radius form assembly is provided which includes a plurality of vertical strongbacks and a plurality of horizontal walers. Each of the walers are pre-rolled to a desired radius. The walers are then connected to one another by ball and socket type adjusters which enable the end to end arrangement of the walers to accommodate an overall form assembly having a wide range of curvatures or radii. The plurality of end to end walers and plurality of corresponding strongbacks may define a gang form length. A number of gang form lengths may be connected to one another to create the desired form assembly for the structure to be constructed. The vertical strongbacks may be placed at desired spacings along the horizontal lengths of the corresponding walers by adjustment of connectors on said strongbacks extending through slotted plates on the walers. The exact number and spacing of walers and strongbacks used in the form assembly are dictated by the size and strength requirements of the structure to be constructed.
