Definitions

  • the invention relates to strands individually protected for suspended civil engineering works, structures comprising such strands, and methods of manufacture of these strands.
  • the protective material used in these strands individually protected from the prior art is generally consisting of wax or grease, so that these individually protected strands cannot effectively transmit significant axial forces from their outer sheath to their steel wires twisted.
  • carrier cables formed by bundles of bare strands or strands of steel. These carrier cables are surrounded by a protective layer exterior which can be constituted by paint, bitumen or tubular sheath, but that layer protective is interrupted at the clamps, tight directly on steel.
  • the object of the present invention is in particular to offer an individually protected strand that is likely to be used in load-bearing cables of suspended civil engineering works, so as to avoid disadvantages mentioned above.
  • a strand individually protected from the genre in question is essentially characterized in that the protective material is a elastomer adhering to twisted steel wires and the inside of the sheath.
  • the agent bonding agent can for example be chosen from terpolymers ethylene - acrylic ester - maleic anhydride and grafted polyethylenes.
  • the invention also relates to a suspended civil engineering structure, in particular suspension bridge or suspended cover, comprising at least two pylons, at least one carrying cable extending between two anchors on the ground and supported by the pylons, and a structure of civil engineering suspended from the carrying cable via lines which are each hung on a collar rigidly fixed to the carrying cable by tightening around this cable, characterized in that the carrying cable consists of at least one bundle of strands individually protected as defined above.
  • the suspension bridge shown in Figure 1 conventionally comprises an apron 1, two pylons 2, two parallel carrier cables 3, only one of which is visible on the drawing, and a plurality of lines 4 which are attached to the cables 3, and which carry the apron 1.
  • the carrying cables 3 are stretched between two ground anchors 5 at both ends of the bridge (solid artificial anchors, rock anchors or the case anchorages at both ends of the deck if is a "self-anchored” suspension bridge), and they are supported by pylons 2.
  • the carrying cables 3 are preferably discontinuous in line with pylons 2, with anchoring on these pylons, for example as explained in more detail in the request French patent filed on the same day as this patent application and entitled “Improvements to suspension bridges and their construction processes ".
  • Each carrying cable 3 comprises one or more cylindrical bundles of strands 6 individually protected, one of which is shown in Figure 2.
  • Each of these strands is made up of several twisted steel wire 7, possibly galvanized, which are here seven in number, and are drowned in a elastomer 8 such as polybutadiene or the like.
  • Elastomer 8 is itself covered by a outer sheath 9 of flexible plastic which can be a polyolefin, especially high polyethylene density, or a polyamide.
  • the elastomer 8 adheres to the twisted wires 7, by surface and form adhesion, in particular when the wires 7 are degreased and free of soap wire drawing.
  • this elastomer is bonded, preferably by chemical bond, with the polyethylene sheath 9 high density.
  • the sheath 9 is integral with the steel wires 7, which allows in particular that the applied forces to this sheath parallel to the axis of the strand 6 are suitably transmitted to steel wires.
  • the lines 4 exert on the collars 10 downward pulling forces which have a tangent component to the carrying cable 3, directed in the direction of the slope of the carrying cable: this are these tangential forces which are transmitted by friction with the sheaths 9 of the strands of the carrying cable.
  • Each of the above-mentioned collars 10 forms a jaw made up of two metal shells 12, 13 substantially semi-cylindrical, which are tight around the cable 3 by means of bolts 14.
  • the carrying cable 3 is surrounded by a plastic folder 15 to the right of each collar 10, so as to prevent the sheaths 9 of the strands components of the carrying cable are injured by the collar 10, in particular when adjusting the position of this necklace.
  • the shirt 15 can consist for example of two semi-cylindrical shells in high polyethylene density, and preferably interstitial spaces between the periphery of the carrying cable 3 and the shirt 15 are filled with solid material 16 in synthetic foam, especially neoprene foam, to obtain a good distribution of the clamping forces of the collar 10 on the entire carrying cable 3.
  • the protective material 8 is polybutadiene or similar and that the sheath 9 is made of polyethylene or similar, for example, it can be used as a bond an ethylene terpolymer - acrylic ester - maleic anhydride, for example that marketed by ATOCHEM (FRANCE) under the brand "LOTADER”, or another grafted polyethylene, for example the one sold under the brand name "OREVAC PE” by the same company ATOCHEM, or any other suitable liaison agent.
  • ATOCHEM FRANCE
  • another grafted polyethylene for example the one sold under the brand name "OREVAC PE” by the same company ATOCHEM, or any other suitable liaison agent.
