Abstract:
1. A method for producing concrete elements, particularly semi-finished concrete products, the method comprising: filling a first layer of concrete mass into a formwork and allowing the first layer to set, resulting in at least a semi-set first layer of concrete mass; placing a reinforcing mesh onto the semi-set first layer, wherein the reinforcing mesh consists of conventional welded wire mesh; filling a second layer of concrete mass into the formwork on top of the first layer and the reinforcing mesh and allowing the second layer to set, resulting in at least a semi-set second layer of concrete mass; pressing modules ( allowing the first and second concrete masses to set and removing the resulting semi-finished product from the formwork, wherein the lattice-work is open toward one side, the one side being downward, wherein lattices of the lattice-work that are situated adjacent to this open side are inclined relative to a lattice of the lattice-work that is situated opposite of this open side by an angle of approximately 90° to 120°, and wherein the modules are produced by caging the displacers (
