FILTERING WALL FOR EXPENDABLE FORMWORK, MEANS FOR MAKING SAID FILTERING WALL AND FORMWORK EQUIPPED WITH SAME

摘要

The invention relates to a filter wall intended to a disposable formwork comprising a mesh (2) formed by assembly of flexible wires of the warp and weft yarns, this lattice is stretched over a so-called indéformable.cette wall is characterized in that: - on the one hand, some of the warp yarns are more resistant than the other warp threads, the voltage of the mesh (2) being created by traction only on these warp yarns, more resistant and - the other hand, it comprises means (3,4,5) for maintaining the voltage of the warp yarns more resistant to the nondeformable structure, these means (3,4,5) for holding a voltage defining a size greater than that resulting from the intersection of warp and weft threads.
