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.

[ What is claimed is:] [1.] An adjustable radius form assembly for use in the construction of structures having curved shapes, said form assembly comprising:at least two walers having adjacent ends connected together at a connection at said adjacent ends thereof, said walers being pivotable with respect to one another at said connection; andat least one adjuster connected between said at least two walers, said adjuster including a stabilizing member and at least one receiving member in the form of at least one ball-shaped member for receiving said stabilizing member therethrough, said adjuster further including at least one securing member in the form of at least one socket member for securing said receiving member at a desired position along said stabilizing member, said desired position defining an angular relationship of rotation between said at least two walers.
