Definitions

  • the invention relates to devices for juxtaposing laterally, then holding laterally juxtaposed, the multiple strands constituting a very long guy wire or cable of the same kind.
  • each guy is formed by a plurality of strands individually protected by plastic sheaths and juxtaposed laterally against each other.
  • Such mutual lateral juxtaposition can be carried out along relatively large surfaces when the section of each strand is hexagonal, which constitutes a preferred, but not exclusive, case.
  • Figure 2 shows the same section of guy at the end of the installation of the clamping device.
  • FIGS. 5 and 6 respectively show from the front along arrow V, FIG. 6, and from the side according to arrow VI, FIG. 5, a cord assembly member established according to the invention and suitable for equipping the clamping devices above.
  • the first cable 5 is wound substantially in a helix around the shroud 1.
  • This second cable 6 extends along the stay 1, parallel to the middle line thereof, and it is assembled in advance on the first cable 5.
  • This member 7 consists of two identical circular plates 8 each hollowed out in one of their faces by a diametrical groove 9 suitable for serving as a housing adjoining a section of a cable 5 or 6 and these two plates are assembled one against the other, in particular by means of rivets 10, in such a way that each groove 9 is open in the direction of the other groove and that, in projection on a transverse plane perpendicular to the axis of each plate, the two grooves are inclined to each other by the angle ⁇ above.
  • This angle ⁇ is generally between 5 and 10 °, preferably being of the order of 7 °.
  • the inextensible cords or cords 5 and 6 are advantageously constituted by bundles of twisted stainless steel wires, bundles surrounded by plastic sheaths.
  • the second cable 6 is unwound next to the end of the shroud thus surrounded by the first cable 5 and the two cables are assembled, without the possibility of mutual displacement, at their predetermined crossing points, using the members 7 taking take care to substantially align these organs in the longitudinal direction of the stay.
  • the friction resistance opposed to the traction in question by the cable 5 wound in a helix is higher but relatively low.
  • This device has many advantages over those previously known and in particular that of being very economical, that of being very easy to install and that of reversibility since the dismantling of the cables 5 and 6 is entirely possible. by simply removing the traction exerted on these cables.
