The invention relates to a reinforcing element (1) comprising a first (2) and a second reinforcing mat (3) having metal mat rods (6), which are welded at angles to each other at junction points (7), which reinforcing mats (2, 3) are held spaced apart from each other at a normal distance (9) by rod-shaped spacers (8) with respect to the first mat plane (4) and the second mat plane (5) of the reinforcing mats. The spacers are metal (8) and are permanently connected to individual mat rods (6) of the first (2) and second reinforcing mat (3) by welding connections (10), preferably resistance welding connections, wherein at least individual spacers (8) protrude outward at least beyond the first mat plane (4) of the first reinforcing mat (2) in a direction (11) pointing away from the second reinforcing mat (3) by a first protrusion length. The invention further relates to a double wall furnished with the reinforcing element and a method for producing the reinforcing element and the double wall.

A wall assembly for a building structure, uses (i) an inner shell cast in a first mold to define a first panel of concrete having a plurality of stiffener members embedded in the concrete so as to be at least partly exposed at the inner side of the panel, and (ii) an outer shell cast in a second mold to define a second panel of concrete having a plurality of stiffener members embedded in the concrete so as to be at least partly exposed at the inner side of the panel. The inner shell and the outer shell are mechanically coupled after casting to define a mold cavity between the inner sides of the panels. Field concrete can be cast into the mold cavity between the inner and outer shells once the wall assembly is mounted on site into position within the building structure.

A reinforcing element includes a first and a second reinforcing mat having metal mat rods, which are welded at angles to each other at junction points, which reinforcing mats are held spaced apart from each other at a normal distance by rod-shaped spacers with respect to the first mat plane and the second mat plane of the reinforcing mats. The spacers are metal and are permanently connected to individual mat rods of the first and second reinforcing mat by welding connections, preferably resistance welding connections, wherein at least individual spacers protrude outward at least beyond the first mat plane of the first reinforcing mat in a direction pointing away from the second reinforcing mat by a first protrusion length. Further, a double wall is furnished with the reinforcing element and a method produces the reinforcing element and the double wall.

A computerized method for measuring a production pallet for precast concrete component parts for the construction industry and/or at least one component, preferably at least one precast concrete component part, preferably wall element, ceiling element and/or double wall element, arranged on the production pallet. The method includes: moving the production pallet relative to at least one measuring device, preferably via a gantry or a cantilever arm, to scan the production pallet, creating at least one depth image in a direction orthogonal to the production pallet by the at least one measuring device, and determining a production pallet height and/or a production height of at least one component arranged on the production pallet orthogonal to the production pallet by a computing unit via the at least one depth image in at least two positions of the production pallet spaced apart from each other.
