Abstract (en)
[origin: EP2241700A2] The concrete dowel (3) has a metal plate (4) extending transversely through a cavity between an upper concrete shell (1) and a lower concrete shell (2). Openings (5) are arranged on top of each other in the metal plate and form teeth (9, 10) that are aligned against each other. A pressure distribution body (11) is arranged in an area between the teeth. A spiral coil (12) e.g. double-conical spiral coil, is designed as the pressure distribution body. A winding of the spiral coil is mounted on the teeth in a form-fit manner.
