Abstract
A corrosion-resistant tension member, particularly a tendon for prestressed concrete, comprising a bundle of tension elements arranged inside a sheathing, has at its ends anchoring devices each with an anchor plate. On the side of the anchor plate facing away from the open air side, a seal having tension elements running through it and having a sealing plate are arranged, the sealing plate being fixed in place on the side facing away from the anchor plate opposite the anchor body against longitudinal displacement. Between the anchor plate and a pressure plate butting against the sealing plate, pressure-transferring means, for example, a pressure tube, are provided, having a length calculated in such a way that a longitudinal displacement of the anchor plate that occurs when the tension elements are being tensioned, actuates the exertion of surface pressure to the sealing plate for activating the seal.
