Abstract
Device for producing a prefabricated cast concrete element having a plurality of central structural elements each comprising two parralel welded wire lattice mats, straight bridging wires welded at each end to the two wire lattice mats holding the wire lattice mats at a predetermined mutual separation and an insulating member penetrated by the bridging wires arranged with its cover surfaces parallel to the wire lattice mats and at a predetermined distance to the latter and having two concrete shells which each adjoin the insulating member and completely enclose the wire lattice mats of the structural elements, characterized in that a plurality of central structural elements are each arranged with their narrow sides abutting one another with selectable spacing between two shuttering walls and the spaces between the insulating members of the structural elements and the shuttering walls completely filled out with concrete.
