A method for producing a double wall with the following method steps: - providing a first reinforcing mat with metal mat rods, which are welded at angles to one another at junction points; - positioning rod-shaped spacers with respect to the mat rods of the first reinforcing mat; - welding the spacers to the mat rods of the first reinforcing mat, characterized in that the method moreover comprises the following method steps: - applying an essentially plate-shaped insulation element to the first reinforcing mat, wherein the insulation element is penetrated by the rod-shaped spacers; - positioning a second reinforcing mat at a normal distance to the first reinforcing mat, wherein the second reinforcing mat is positioned such that the spacers extend between the first reinforcing mat and the second reinforcing mat; - welding the spacers to the mat rods of the second reinforcing mat for providing a three-dimensional reinforcing element; - providing a horizontally oriented formwork pallet and attaching limitation formworks on the formwork pallet; - applying a concrete layer onto the formwork pallet; - immersing the first reinforcing mat of the reinforcing element in the concrete layer, with jolting the formwork pallet and/or of the reinforcing element as required; - storing the component until solidification or hardening of the concrete layer to a first wall shell; - raising the reinforcing element including the first wall shell attached thereto off the formwork pallet; - flipping the reinforcing element including the first wall shell attached thereto; - providing a horizontally oriented formwork pallet and attaching limitation formworks on the formwork pallet; - applying a concrete layer onto the formwork pallet; - immersing the second reinforcing mat of the reinforcing element in the concrete layer, with shaking of the formwork pallet and/or of the reinforcing element as required; - storing the component until solidification or hardening of the concrete layer to a second wall shell. - providing a first reinforcing mat with metal mat rods, which are welded at angles to one another at junction points; - positioning rod-shaped spacers with respect to the mat rods of the first reinforcing mat; - welding the spacers to the mat rods of the first reinforcing mat, - applying an essentially plate-shaped insulation element to the first reinforcing mat, wherein the insulation element is penetrated by the rod-shaped spacers; - positioning a second reinforcing mat at a normal distance to the first reinforcing mat, wherein the second reinforcing mat is positioned such that the spacers extend between the first reinforcing mat and the second reinforcing mat; - welding the spacers to the mat rods of the second reinforcing mat for providing a three-dimensional reinforcing element; - providing a horizontally oriented formwork pallet and attaching limitation formworks on the formwork pallet; - applying a concrete layer onto the formwork pallet; - immersing the first reinforcing mat of the reinforcing element in the concrete layer, with jolting the formwork pallet and/or of the reinforcing element as required; - storing the component until solidification or hardening of the concrete layer to a first wall shell; - raising the reinforcing element including the first wall shell attached thereto off the formwork pallet; - flipping the reinforcing element including the first wall shell attached thereto; - providing a horizontally oriented formwork pallet and attaching limitation formworks on the formwork pallet; - applying a concrete layer onto the formwork pallet; - immersing the second reinforcing mat of the reinforcing element in the concrete layer, with shaking of the formwork pallet and/or of the reinforcing element as required; - storing the component until solidification or hardening of the concrete layer to a second wall shell.
