Definitions

  • the present invention relates to a work in particular a bridge, comprising at least one bundle of cables or son.
  • Other possible works are frames, suspension or guyed bridges, or the like.
  • the present invention relates to a work of the kind previously mentioned, which provides protection particularly good with respect to humidity and the aggressive external environment of the cable harness, and this in a simple way and without requiring major maintenance during the lifetime of the structure.
  • a book in particular a bridge, comprising at least one beam of cables, and periphery protection means outside of the beam, is characterized in that the means of protection have a band, of a material heat-shrinkable, arranged so as to wrap by tight fit, wiring harness or wires.
  • the strip forming part of the cables beam does not imply significant change in the final dimensions of the structure, which ensures that it is not necessary to provide additional measures to take into account for example wind effects.
  • the heat-shrinkable material being plastic, it does not transmit additional constraints cables and therefore it is not necessary to provide specific expansion joints.
  • the present invention also relates to a work, in particular a bridge, comprising at least one bundle of cables and a metal collar, arranged so as to wrap the or cables or wires, the cable bundle being wrapped by a tight fit with a strip of material heat shrink, and the junction between the collar and the strip of heat-shrinkable material enveloping the cables is made tightly by means sealing.
  • necklaces instead of necklaces, it can actually be also anchor chamber entrances at the level of ends of cable harness (es), saddles beam supports, cable deflectors, or cable hanging caps.
  • cable harness es
  • saddles beam supports es
  • cable deflectors e.g., cable hanging caps.
  • the seal between the strip of heat-shrinkable material and the metal collar is made by covering the edge outside of collar by band or piece of band additional in heat-shrinkable material.
  • the strip of heat-shrinkable material will also shrink on the metal collar and therefore, ensure a good seal at the junction between the heat-shrinkable tape and the collar metallic.
  • the means sealing are constituted by a groove made at inside the collar, into which the band enters heat-shrinkable material, a bead of sealant being disposed over the entire annular groove around the heat-shrinkable tape, for sealing.
  • the strip heat shrinkable is stopped on the bare metal collar, and a bead of sealant is provided, arranged so as to make a blockage between the strip and the end of the collar.
  • a special molded or fixed part is provided by screw on the collar, a first strip being inserted between the special part and the beam and a second strip fitting covering the outside of the room and the first bandaged. If there is not enough clearance between the special room and the beam, the first strip stops at the nude before the special piece and the second strip overlaps, as specified above.
  • the heat shrinkable material is polyethylene reticle.
  • the strip of heat-shrinkable material is wrapped around the wire harness so helical.
  • the heat-shrinkable tape consists of a plurality of sub-bands of heat-shrinkable material wound perpendicular to the beam and overlapping each other over an overlapping distance.
  • the strip of heat-shrinkable material is consisting of a support made of coated heat-shrinkable material completely or partially only in areas where it is necessary to have an underlying bonding, on its face inner side of hot-melt adhesive, especially putty.
  • a structure in particular a bridge, comprises at least a bundle of cables and means of protection of the outer periphery of the beam, the means of protection comprising a strip of heat-shrinkable material, arranged so as to tightly wrap the bundle of cables or wires, the strip having two lips from the outside of the two opposite edges longitudinal of the strip in contact with each other for allow the wiring harness to be wrapped by the strip, the two lips being adjacent via of a contact face and each comprising a bead extending substantially perpendicular to said face of contact, so that you can put on a slide joint support to grip the lip beads adjacent to hold lips together during heat shrinkage and then possibly remove this slide or keep it in place for ensure over time, for additional security bonding, mechanical maintenance of the two edges in contact.
  • these tapes are available as rolls or sheets in great length in the direction parallel to both lips. Thanks to this lip system and slide, it is possible to deposit the strip on the cable by unrolling the strip not perpendicular to the beam but longitudinally parallel to it. Therefore, it avoids the connections between two widths of adjacent strips each winding a part of the beam. It is now possible to have a band arranged on the cable bundle of only one length between two necklaces and therefore in a much simpler way without having to make sure that the connections are tight.
  • one of the lips is set back from its respective edge of the strip. This allows, when bringing this lip into contact with the contiguous lip from the other edge of the strip, to obtain a mutual overlap of the two edges of the strip and therefore a good tightness after shrinking, as well as bonding on the underside of the lips.
  • This collage is improved usually by interposing a sufficiently wide ribbon (about 8 cm) of a hot-melt adhesive previously glued on the underside of the heat-shrinkable tape under the edge of the strip which covers the other edge.
  • This ribbon longitudinal hot-melt adhesive by fusion during heating of the strip for heat shrinking, by force of radial compression exerted by the shrinking of the material heat-shrinkable, further improves sealing between the two overlapping edges of the strip.
  • the beads are semi-circular in shape.
  • the present invention also relates to a work in particular a bridge comprising at least one bundle of cables and means for protecting the outer periphery of the beam, characterized in that the means of protection have a strip of heat-shrinkable material arranged so as to tightly wrap the bundle of cables or wires, the strip having two lips from the outside of the two opposite edges longitudinal of the strip, the two lips being adjacent by a contact face and each comprising a bead extending substantially perpendicular to said face, and a slide is provided so as to enclose the two beads longitudinally.
  • This system provides excellent support of the two edges of the strip while their necking is performed.
  • lights for assist in thermal transfer to the product shrink wrapped in the slide, to obtain a best shrunk. These lights also allow give sufficient longitudinal flexibility to the slide as well as the attachment of a special pulling tool for put the slide more easily on the lips.
  • the slide is made of stainless steel for ability to leave it in place on the structure and avoid its corrosion.
  • band-collar fittings described previously also apply to this type of bands heat shrinkable with lips and zipper.
  • This second strip extends beyond the collar side of the band with lips and zipper to close at the end the tip of the roughness formed by the lips and the slide and thus achieve a good seal.
  • a cable bundle is made up of several cables 1, made of steel, arranged one against the others so that the cross section of the beam is for example substantially circular. Other forms geometric cross section of the beam of cables, such as polygonal, hexagonal or square are possible.
  • 2, 2 ', 2 strips of material shrink wrapped around the bundle of cables 1.
  • the bands 2, 2 ', 2 are in direct contact with the wiring harness.
  • Figure 1a it is not shown that two bands like this. It goes without saying, however, that everything the cable bundle should normally be surrounded by bands Of this genre. For convenience of drawing, only two of these plates have been shown.
  • the 1 carrier cables are intended to support a bridge deck (not shown). This is done by through a hanger, which is attached to one of its ends to the apron and which includes at its other end a hanger clip or stirrup 4 which is suspended from load-bearing cables with interposition of a collar 5, the shape is adapted to the shape of the outer periphery of the harness, for hanger attachment.
  • This necklace 5 is made up, as best seen in Figure 3a, of two upper and lower half-collars 6 and 7 which are tight one against the other by screw and bolt systems 8.
  • These interstices 9 allow the passage of dry air between the cables, inside the envelope formed by the strip 2 made of heat shrinkable material. We can thus dry the environment in which cables 1 are located and effectively fight against corrosion of cables and therefore store for a long service life.
  • the overlapping portion of the strip 2 heat shrink with collar 5 extends beyond screw and bolt systems 8 used to tighten one against each other the half-collars 6 and 7 forming the collar 5.
  • annular groove 10 with a radius smaller than the radius of the circular cross section of the collar, the strip 2 of heat-shrinkable material coming to penetrate in this groove 10 and after heating, shrink therein to ensure a good seal between the strip heat shrink and the collar.
  • a cord is provided sealant, bead 11 which is annular and arranged in the groove 10 between the strip of material heat shrink 2 and clamp 5.
  • FIG. 5a and 5b Another embodiment of the junction waterproof between the strip 2 of heat-shrinkable material and the collar 5 is shown in Figure 5a and 5b.
  • the strip of material shrink wrapped around cables 2 up to the bare collar 5.
  • a bead 12 of mastic sealing is deposited along the periphery of the strip 2 at the connection part with the collar 5.
  • FIG. 6 is represented yet another mode for making a tight connection between the strip of heat-shrinkable material 2 and the collar 5.
  • the strip of material heat shrinkable 2 extends to the end of the collar 5.

  • a strip of heat-shrinkable material 15 auxiliary is applied to the branch of the part 13 which is in contact with the strip 2 made of material heat shrinkable so that this branch is fully wrapped in heat shrinkable material.
  • the dry air supply means intended for allow the circulation of dry air in the interstices (9) between the strip (s) and the cables (1).
  • tappings can be provided at the low point of the collars to allow the outlet of the condensation water which would have formed in the beam if there is no system of dehumidification.
  • the pulls supported by the bundles of cables or wires according to the invention are included in the range from 30 to 250 kg / mm 2 , preferably 60 to 180 kg / mm 2 .
  • the temperature at which the material shrink shrinks on the beam is at least 80 °, to prevent natural heat, for example linked prolonged exposure to the sun does not cause the material. This temperature is preferably between 100 ° and 250 °.
  • a strip 2 'surrounding a bundle of cables 1, overlapping a small distance which is 30 mm and is generally between 20 and 70 mm.
  • a lip 35 protrudes.
  • This lip 35 is consisting of a base delimited externally by a face outer 36 and a bead 37 extending perpendicular to the contact face 36.
  • the bead is semi-circular in shape. It could be from another for example square shape.
  • the lip 38 also includes a bead extending perpendicular to this contact face 36.
  • the bead may be of the same shape as the bead 37, or be of a other form.
  • the two beads are generally the same shape so as to have a symmetrical slide.
  • the lip projection height 35 and 38 is about 5 to 8 mm depending on the bands.
  • the recessed lip 38 is tall less than that of lip 35, the difference corresponding to a strip thickness, so that the two lips 35, 38 have their peak in outcrop.
  • the base lips about half the height mentioned above, the other half corresponding to bead diameter at the top.
  • the lips longitudinal profiles extend over the entire length edges of the strip 2 '. Around those lips, surrounding their bead, there is a metallic slide 39, especially stainless steel.
  • the material band heat-shrinkable consists of a material support heat-shrinkable which can be coated on one of its faces, in the specific case on the face opposite the lips, a hot-melt adhesive, especially putty, if we want to get a bond between the strip and the cables.
  • a hot-melt adhesive especially putty
  • the tape will made of a heat-shrinkable material not coated with putty inside. In the latter case, there will only be the tape 41 of 8 cm hot-melt adhesive material about width previously glued under the edge 32 to bond the two edges.
  • Slide 39 has lights 40 distributed uniformly according to its length.
  • the heat-shrinkable material is heated which will shrinking to tightly wrap the cables.
  • the lights 40 allow the thermal means to reach the polyethylene material inside the slide 39 to allow a good constriction also at the level of the contact face 36.
