  • Patent number: 10738422
    Abstract: The present invention concerns a cable anchorage comprising at least one axial channel for accommodating an elongated element with a sheathed portion and an unsheathed end portion, wherein the channel between a first channel end, proximal to a running part of the elongated element, and a second channel end equipped with immobilising device, a seal element in the channel, a stop element having an end facing said seal element which defines a shoulder, so that an axial displacement of the of the elongated element with respect to the stop element in said channel is possible up to the abutment of the end of the sheathed portion against the shoulder, creating thereby an abutment position of the elongated element in said channel.

  • Patent number: 9850630
    Abstract: A cable anchorage anchors a cable, for example a stay cable having multiple strands (50), against a longitudinal tension force. The anchor block (11) of the anchorage includes multiple channels, through which the strands (50) are individually threaded. Once in position and tensioned, the space around the strands (50) in the anchor block (11) is injected with a liquid, such as a polyurethane, which subsequently sets to form a tough elastic bedding material (51) within the anchor block (11). The elastic bedding material (51) has a durometer at 23° C. in the range 10 to 70 Shore, so as to form bedding cushion extending substantially around the strand (50) in the strand-channel (6) along a bedding region (54) of strand-channel (6), the bedding cushion reducing the bending stresses in the strand (50) by absorbing bending stresses along the bedding region (54).

  • Patent number: 9790651
    Abstract: A cable anchorage is described for anchoring a cable, for example a stay cable comprising multiple strands (50), against an axial tension force. Each strand (50) is individually sealed in an individual channel (6) of the anchorage against moisture ingress, and each strand (50) may be removed and replaced individually. A tight-fitting elastic annular seal (26) is fitted into a recess (27) in the channel. The annular seal (26) is inserted from the anchor block end (1) of the anchorage.

  • Patent number: 7900306
    Abstract: Guiding device (1) for strands (2), the guiding device (1) comprising a body (5) in which at least one curved channel (6) is made, including a longitudinal axis curved according to the curvature of said channel (6) and a first part (8) which, situated in principle at the side of the intrados of the longitudinal axis (7), permits, in the limit of the length of the channel (6), the support of the strand (2) on at least one portion of the peripheral face (10) which this strand (2) presents.

  • Publication number: 20020108329
    Abstract: A device (1) is disclosed for anchoring one end (2A) of a stay (2) to a base (3), this end (2A) of the stay (2) comprising at least two strands (2B) which diverge from its longitudinal axis (2C) in such a way as to come to be anchored in the device (1), these strands (2B) each being made up of a core wire (2D) and a protective sheathing (2E), the device itself being intended to be positioned and immobilised in translation in a bore (3A) provided in the base (3), this device (1) comprising a first rigid unit (4), which:
