Abstract
A corrosion-resistant tension member, particularly an inclined cable of a cable stayed bridge, is comprised of a bundle of individual elements, for example, steel wire strands, which in its open area is encapsulated by sheathing, and which within the structure extends inside a guide canal that is formed by a recess pipe. The sheathing—sealing off the front side of the guide canal—is thereby directly or indirectly connected to the structure. Between the sheathing and the entrance point of the tension member into the structure, a connecting pipe is arranged, which on the one hand is detachably connected to the sheathing and on the other hand is connected to the structure by a flange plate.
