Method of forming cast concrete building shells, usable in civil engineering and public works

摘要

The method involves forming a lightweight coffering and a marine counterplate nailed to the fixed foundations by bolting on the corners along the opening sides. There can be a lattice which is non-ribbed and-or a welded trellis which gives rigidity to the shell after deposition of 3 or 4 cm of concrete. The props are positioned in order that the assembly can be susceptible to support the load of sprayed concrete, the reinforcements and the concrete of the opening.
