The support component, under linear pressure movement, penetrates a base and comprises a conical tubular unit (1) with a number of projecting profiles (2,2') in its longitudinal direction. When the thick end part is pressed into the base, the profiles are expanded diametrically by the entry of base material into the tube, thus forming a considerably expanded collar surface relative to the base. The narrower end part of the conical tubular component can be filled with a reinforcing and support material. |
