A device for producing a prefabricated cast concrete element. The device includes a plurality of central structural elements, each of the plural 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 are arranged on opposing sides of the plural central structural elements, each of the shuttering walls comprising a plurality of sections connectable to one another. A plurality of spacing members composed of rustproof materials are arranged and dimensioned for defining a spacing between each of the plural structural elements and the shuttering walls for receiving concrete for forming concrete shells.
