Abstract

An anchor head for a corrosion-protected prestressable injected anchor secures the end of a bundle of steel members, such as rods, wires or strands. The anchor head includes an abutment member and an anchor plate supported on the abutment member. The anchor plate has bores for receiving and anchoring the ends of the individual steel members. The bundle of steel members extends through a borehole and between the borehole and the abutment member the steel members are fanned or spread out before entering the anchor plate. Each of the steel members is covered with a corrosion protective sheathing. A closure plate is arranged at the abutment member and has a number of openings corresponding to the number of steel members. The steel members pass through the closure plate in a sealed manner.
