Abstract
A forming device for prefabricating structures having a size-adjustable core surrounded by a shell structure displaceable with respect to the core. The shell structure is constructed of a plurality of frame members each independently adjustable with respect to the core. One or more tensioning cables surround the core, the cables being reeved through a series of fixed and movable pulleys mounted at each corner of the shell formed by the intersecting frame members. By operating the cables the frame members are adjustable with respect to the position of the core of the forming device.
