Method and auxiliary means for producing concrete elements, particularly semi-finished concrete products and/or concrete slabs, as well as auxiliary means for producing concrete slabs

Patent number: 7897073

Abstract: Displacers are used in production of concrete surfaces. The displacers are embodied, for example, as plastic balls or plastic shells and are locked in lattices that are open on one side, preferably downwardly. The modules can then be pressed into a first or second concrete layer that can already contain a first reinforcement mesh. The thus produced semi-finished product can then be covered with a concrete mass during the subsequent finishing process.
