Abstract:
1. A device for producing a prefabricated cast concrete element, comprising: a plurality of central structural elements, each of the plurality of central structural elements comprising two parallel 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 wire lattice mats; shuttering walls arranged on opposing sides of said plurality of central structural elements, each of said shuttering walls comprising a plurality of sections connectable to one another; and a plurality of spacing members composed of rustproof materials arranged and dimensioned for defining a spacing between each of said plurality of structural elements and said shuttering walls for receiving concrete for forming concrete shells, wherein the wire lattice mats comprise longitudinal and transverse wires and said spacing members comprise spacing elements having cruciform slits arranged and dimensioned for receiving selected points of intersection of said longitudinal and transverse wires of said wire lattice mats and having ends opposing said cruciform slits braced against said shuttering walls.
