Definitions

  • the invention relates to assemblies comprising on the one hand cables or shrouds having a high tensile strength and composed of a plurality of strands themselves formed individually by sets of parallel or twisted metal wires and on the other hand anchoring structures for the ends of these shrouds.
  • the various constituent strands are generally brought together in a common protective envelope and linked together transversely by a protective binder which fills the intervals between the strands and the envelope.
  • This binder is generally a grout of injected cement hardened after injection.
  • This formula has a certain number of drawbacks such as the high weight and the stiffness of the shroud, the risks of cracking of the hardened grout and especially the fact that the shroud constitutes a one-piece assembly: it is therefore not possible to individually replace the strands which compose it in the case where only some of these strands are damaged, for example following an impact of a vehicle or vehicle loading against the shroud.
  • the protective binder is a grease or the like.
  • the aim sought by this other formula is to make possible the individual replacement of the strands.
  • the object of the invention is, above all, to remedy these drawbacks.
  • the assemblies of the kind in question according to the invention also comprise, in a manner known per se, for example from document JP-A-6 015 035, a perforated block on which the stripped ends of the various are individually anchored strands making up the shroud, an annular bearing surface against which the periphery of the block is applied axially, and a sleeve to which said block is connected on the side of said bearing, the chamber formed inside this sleeve being filled with a material ensuring the protection of the stripped portions of strands present in this chamber, the different strands being protected by sheathing independently of each other, the protective sheath of each strand being interrupted at a terminal wafer at a distance from each end of this strand and the above chamber containing the end sections of the sheaths and being closed in a sealed manner, on the side of the shroud, by a sealing device sheaf tightly traversed by sheathed portions of the strands, and they are essentially characterized in that the protective material
  • the invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.
  • the shroud considered is composed of a plurality of individual strands 1.
  • the number of these strands is generally less than 100, preferably being between 15 and 70.
  • Each strand 1 is itself formed by a plurality of elementary wires 2, for example the number of 7 in the embodiment illustrated in FIG. 4.
  • wires can be parallel or twisted: in the latter case, the corresponding strands are generally designated by the name of "strands".
  • the wires 2 are, for example, made of spun and galvanized steel.
  • All of these wires are surrounded by a protective sheath 3 which is able to protect them during their whole life against corrosion due to bad weather or other external aggressions, and in particular to humidity and handling.
  • This sheath is for example made of a plastic material, such as polyethylene or a polyamide, or a metal such as aluminum or stainless steel.
  • the sheath in question can also be constituted by any other desirable coating of the wire bundle 2, for example by an epoxy paint coated on it.
  • the intervals between the wires 2 and the sheath 3, if they exist, may or may not be filled with a protective substance 4 such as, for example, a resinous pitch of the epoxy type or a wax.
  • Each strand 1 is manufactured in the factory and it is available at the exit of this factory in the form of a site coil.
  • the thickness of the sheath 3 a value low enough to make possible the winding of the strand: if it is a metal, we give said thickness a value of about 1/10 of mm.
  • the sheathed strands 1 thus defined, all identical to each other, are autonomous and remain so throughout the life of the stay they constitute.
  • each jaw 5 has, on the one hand, a cylindrical internal bore suitable for contiguously surrounding the end of the strand to be anchored, and, on the other hand, a frustoconical external surface suitable for cooperating with a complementary housing hollowed out in an anchoring block 6.
  • This cable gland 8 comprises two transverse perforated plates 8 1 , 8 2 between which is interposed a cushion 8 3 made of elastomeric or similar material, and means suitable for bringing the two plates closer together, which causes the cushion to swell while ensuring the sealing desired.
  • Chamber A communicates by a channel 12 with a chamber B provided outside of block 6 and delimited by a cover 13 applied contiguously against this block, by tightening screws 14.
  • the assembly of the two chambers A and B is filled at the end of the anchoring of all the strands 1 on the block 6 with a grease or similar material having simultaneously the following properties: flexibility, weak adhesion with respect to the strands and their bare ends, protection of these ends against corrosion.
  • a ring 15 suitable for resting itself axially against an annular bearing 16 forming part of a structure 17 for anchoring the guy line, structure such as a pylon top or a solid mass on the ground.
  • the portions, stretched strands 1, which are arranged outside of the grease box A, B, can be parallel to each other and be directly exposed to the air.
  • the collar 19 can be easily disassembled, which makes it possible to separate the various strands 1 from each other, it is advantageously constituted by two half-shells which can be assembled and separated at will.
  • the bundle may be left in the open air or may itself be protected by an envelope 20 of any desired nature and size, for example made of polyethylene.
  • each strand 1 and its environment are located at the level of the individual anchors (jaws 5 in the illustrated case): the other elements which are in contact with these strands are the furs 26 and the cushions 8 3 .
  • Each strand can therefore be considered completely autonomous over its entire length and can be stretched or relaxed independently of its neighbors.
  • each strand 1 it may be useful to give the free ends 21 (FIG. 2) of these strands, which protrude beyond the anchoring members, a greater length. than that shown, to facilitate the taking of these ends.
