  • Patent number: 4744691
    Abstract: Anchoring means for anchoring tension members, more especially for anchoring tension cable conductors, comprises at least two clamping components in the form of anchoring wedges which are disposed one behind the other on the tension member and are anchored in at least one anchoring member. The moulding which is more remote from the support structure is harder than, or as hard as, the tension member, while the clamping component which is nearer the support structure is softer than the tension member. The tension member is initially tensioned, then the anchoring wedge of the first anchoring member is pressed in position by the insertion of an intermediate member between the first and second anchoring members; meanwhile, the first anchoring member is supported on the second anchoring member by the intermediate member; then the intermediate member is removed, and subsequently the anchoring wedge of the second anchoring member is pressed in position by the first anchoring member.
