Double wall s owie method for producing a double wall

摘要

The invention relates to a double wall (1) comprising a first (21) and a second wall shell (22) made of concrete, in which the first (21) and second wall shell (22) comprises a reinforcement element (2) is at least partially integrated with the first between the (21) and the second shell wall (22) an insulating element (23) is arranged. The reinforcing element (2) has a first reinforcement mat (3), which is integrated into the first wall shell (21) and a second reinforcing mat (4) which is integrated into the second wall shell (22). The reinforcement mats (4) have in nodes (8) angularly mutually welded metallic Matt rods (7) are and respect their first (5) and second mat layer (6) by rod-shaped spacer (9) in a normal distance (10) to each other kept aloof. The spacers (9) are metallic and are non-detachably connected by welds (11), preferably resistance welded joints, with individual Matt rods (7) of the first (3) and the second reinforcing mat (4). Furthermore, the invention relates to a method for producing the double-wall (1).
