Abstract
An anchoring device for a corrosion-protected tension member includes an anchor body, which is provided with bores for the passage of the tension elements. Sealing discs, which can be compressed by means of a pressure plate and threaded bolts, are provided on a face of the anchor body and lie opposite a downstream face. A perforated disc, which is enclosed by two supporting discs, is located downstream of the sealing discs and the pressure plate. The perforated disc acts as a spacer for the tension elements and is fixed between lugs that are opposite an anchor tube and that is connected to the anchor body. The locking of the perforated disc enables the position of the tension elements to remain parallel, even when the sealing discs are compressed to activate the seal. If individual tension elements have to be replaced, the loosening of the threaded bolts allows the sealing discs to 'breathe' and to return to their original position.
