Formwork for producing concrete bodies in e.g. building site, has permeable carrier layer arranged at sub-construction, and dimensionally stable formwork surface detachably connected with permeable carrier layer

摘要

The formwork (1) has a permeable carrier layer (3) arranged at a sub-construction (2). A formwork surface (4) is dimensionally stable and detachably connected with the permeable carrier layer, where the formwork surface consists of metal and/or metal foil. The carrier layer has a raster-like structure i.e. honeycomb structure, oriented with respect to the formwork surface. The carrier layer is developed from multiple of longitudinal hollow bodies, where length of hollow bodies is larger than cross section of the hollow bodies.
