Abstract
Apparatus for erection of arcuate walls of poured concrete has one or more deformable sheathings secured to turnable supports which are movably secured to one another by composite girders having alternating rigid variable-length links and fixed-length connectors which are affixed to the supports. The angular positions of the supports are changed by changing the length of the links. Locking devices are provided to hold the links against angular movement relative to the neighboring connectors when the sheathing assumes the desired shape. The locking devices can constitute separable components or they may be permanently mounted on and/or integrated into the links and/or connectors.
