| 摘要 |
The invention relates to a reinforcing element (1), comprising a first reinforcing mat (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 (8) are metal and are permanently connected to individual mat rods (6) of the first reinforcing mat (2) and of the 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 equipped with the reinforcing element and to methods for producing the reinforcing element and the double wall. |
