  • Patent number: 9446541
    Abstract: The method is for protecting the end of a cable made of a plurality of parallel tendons (10) anchored using a block (15) having a front side, a rear side and channels (16) extending between the front and rear sides. Each tendon of the cable is held in a respective channel of the anchor block with a blocking member (19). The method comprises performing a first phase of injecting protective material (100) into at least some of the channels of the anchor block. A chamber (30) is formed on at least one side of the anchor block (15) so as to contain portions of the plurality of tendons. A second phase of injecting protective material (200) into the chamber (30) is then performed.

  • Patent number: 9085832
    Abstract: A strand (3) comprising a group of twisted threads (8) and arranged so as to have, over a first part (1) of its length: a sheath (4) containing the group of twisted threads, and a flexible filling product (7) filling a peripheral interstice (6) located between the inner face of the sheath and the periphery of the group of twisted threads, and, over a second part (2) of its length, which is separate from the first part: a material (9) covering the periphery of the group of twisted threads, said material adhering to the twisted threads of the group.

  • Patent number: 8959692
    Abstract: The structural cable has several stretched tendons (4). It is diverted in a device comprising a body crossed by conduits (10). Each conduit has a wall to guide one of the tendons along a curved path. The wall of the conduit has a tendon support area (11) directed toward the interior of the curve of the path. This support area presents, in the center portion of the conduit and transverse to the curved path, a section in the shape of a circular arc whose radius is appreciably equal to half the external diameter of the tendon. The central portion of the conduit has a cross-section enlarged outside the support area.

  • Patent number: 8769921
    Abstract: To protect the end of a cable composed of a set of tendons individually held in an anchorage system, the device comprises a skirt extending from the front of the anchorage system and placed around the set of tendons, and several sleeves. The tendons have respective end portions which extend beyond the front of the anchorage system and which are individually received in the sleeves, said sleeves being sealed off beyond the end portions of the tendons. A connection between the skirt and the sleeves encloses a chamber delimited by the front of the anchorage system, the skirt, and the sleeves, the connection comprising an active stuffing box kind of system. The volume of this chamber is filled in with a filling product.
