摘要
The concrete part has a moulded section (1) that has a rubber-elastic profile (2) in the shape of a rainwater groove positioned on the underside. The rubber-elastic profile has bars (2a) which protrude slightly from the base. The profile is made of rubber and the surface, at least one the side facing the moulded concrete section, has a degree of roughness sufficient to ensure good adhesion. A metal sleeve (7) is embedded in the moulded section. IMAGE
