<p>The element (1) has two formwork boards (2a, 2b) for defining a formwork plane (E), where the boards are aligned to each other by releasing a joint sealing gap (5) and made of formwork material e.g. perforated metallic sheet. The boards have rear sides and front sides turned toward concreting portions (BA1, BA2), respectively. A reinforcing element (3) connects the boards with each other over the sealing gap, and is fastened at the rear sides. The boards form a gearing rib (4) projecting from the plane in a direction of the rear sides, and the sealing gap is arranged in a gearing rib region. An independent claim is also included for a slotted wall reinforcing cage comprising a reinforcing cage unit.</p> |
