Anchoring device for fixing a structural cable to a building element

Anchoring device for securing a structural cable to a building element, said cable comprising a number of strands each of which comprises metal wires themselves enveloped together in a protective sheath, each of the protective sheaths being interrupted at a terminal edge so that the strands each has a bared end portion, the anchoring device comprising:

• a perforated block in which the bared end portions of the various strands are individually anchored;
• a bearing surface which is secured to the building element and against which the periphery of the perforated block axially bears;
• a tube to which the perforated block is attached on the bearing surface side, the tube transversely delimiting a chamber inside which the terminal edges of the strands are located and which is filled with a substance that protects the bared end portions present in the chamber;
• a packing box which seals the chamber, at the opposite end to the perforated block, and which has the strands passing in a scaled manner through it, the packing box comprising:
• at least two perforated plates of which one, known as an inner plate, is arranged on the same side as the chamber and of which the other, known as an outer plate, is arranged at the opposite end to the packing box with respect to the inner plate;
• and
• at least one piece of packing which is inserted between the inner plate and the outer plate, the outer plate being stationary with respect to the chamber;
• and
• pressing means for pressing on the inner plate.
