Definitions

  • the invention relates to anchoring devices for stretched cables and more particularly those of these devices, for which relative variations in inclination are likely to appear between the device and the cable when the latter is loaded.
  • Such cables are, for example, the cables making up the stay cables for the suspension of bridges: the overloads applied to these bridges after the installation of their stay cables can indeed slightly deform their suspended decks and therefore the inclinations of the cables relative to their devices. anchoring or vice versa.
  • the cable traction cylinder is then itself mounted on the ball joint around this cable.
  • the cable pulling cylinder, surrounding the anchoring head is not mounted on the ball joint integral with this head, but on a second ball joint larger than the first and itself received in a second bowl carried by the first, this formula makes it possible to make the cylinder coaxial with the anchoring head even when the latter is inclined relative to normal to the flat surfaces for carrying the plate and the bowls, and therefore exert pulls on the cable so "inclined", but it does not vary the inclination of the anchor heads under load.
  • the invention aims, above all, to make possible such variations under load.
  • the anchoring devices of the type in question according to the invention also comprise a traction cylinder arranged around the anchoring head and a convex spherical bearing secured to this head and capable of interacting with an annular bearing of the plate, and they are essentially characterized in that they comprise an annular shoulder attached to the free end of the anchoring head and delimited on the side of the plate by a second convex spherical bearing concentric with the first and in that the cylinder is interposed between the plate and the shoulder and has a concave spherical bearing capable of interacting with the convex spherical bearing of the shoulder so as to make possible a sliding under load of this shoulder relative to the jack.
  • 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.
  • Figure 1 of this drawing shows schematically in axial section a cable anchoring device established in accordance with the invention after tilting the cable under load and before correcting the orientation of the anchoring head.
  • Figures 2 and 3 show substantially the same device respectively during the correction and after it.
  • the tensioning cable 1 which is for example intended for the guying of a bridge, is terminated by a rigid head 2 externally threaded.
  • this head 2 that is to be anchored.
  • a solid 3 made of metal or reinforced concrete, hollowed out by a hole 4 of axis X suitable for delivering passage to the cable 1, or more precisely on a annular metal support plate 5 attached to this block 3 and hollowed out like this.
  • said head 2 or “anchoring head” is surrounded by a nut 6 screwed onto it and itself having a convex spherical bearing 7 suitable for resting on an appropriate annular bearing 8 of the plate 5, carried coaxial with hole 4 and generally frustoconical.
  • the two spherical surfaces 10 and 14 have the same radius of curvature and at least one of these surfaces is made of a hard and non-deformable material. They are machined and treated in such a way that they can easily slide against each other even under load and so that the axis of the head 2 can align rigorously with that of the cable 1 harnessed on this same head when this cable is heavily loaded.
  • liquid lubricant such as engine oil
  • This lubricant is discharged to the interface concerned under a high pressure (for example between 500 to 1,000 bars) through pipes 16 and distribution grooves 17, then recovered in the state of leakage on the edges of the surface.
  • a high pressure for example between 500 to 1,000 bars
  • the shoulder 9 is preferably removably mounted on the head 2, for example by screwing, so that it can be recovered just like the jack 11 in order to successively correct the orientations of separate heads 2.
  • the head 2 of this cable, anchored on the block 3 is coaxial with the hole 4 of axis X and the nut 6 is oriented coaxially to this hole with its bearing surface 7 resting on the bearing surface 8 of the plate 5.
  • the Y axis of the cable 1 occupies an inclined position at an angle ⁇ relative to the X axis ( Figure 1).
  • the interface between the spherical bearings 10 and 14 is lubricated in the manner specified above.
