Definitions

  • the present invention relates to the devices used to anchor structural cables used in the construction of engineering structures. She applies in particular to stays, prestressing cables and cables of suspension bridges.
  • the stay cables are cables generally intended to transmit tensile forces between two points of a structure where they are anchored. They are in theory straight if we neglect the external effects that tend to curving their trajectory.
  • the constitution of the anchors is generally such that only the effort traction is resumed satisfactorily.
  • Local bending moments caused by the angular deviations mentioned above which could request anchoring are filtered by means of a continuous or isolated guide at the exit anchorage and located at a suitable distance to be sufficiently effective.
  • the principle of anchoring is based on the individual each of the strands constituting the cable. This imposes a certain spacing transversal strands at the anchor block to have enough room to dispose of the individual jamming means which are generally jaws with frustoconical keys.
  • a diverter pulls the strands into one compact arrangement at a certain distance from the anchor, in order to minimize the overall cross section of the stay in the current part.
  • the guide that filters the bending moments is located at the level of the deflector which collects the strands in compact formation (see for example EP-A-0 323 285).
  • the relatively large distance between the guide and the anchor block (typically more than one meter) is necessary to limit deviations excessive angularity of each strand, which could damage it and would translate into additional bending moments at the block level anchor.
  • resume bending moments too close to the anchor would leave significant transversal efforts at the level of the block anchor.
  • GB-A-2 157 339 discloses a guy stay anchoring device in which a deflector is mounted in two parts in a tube secured to the block anchor.
  • the furthest part of the anchor block avoids the contact of outer strands with the tube, while the nearest part of the block Anchorage prevents friction of the strands between them when loads cyclic are applied to the stay. Bending moments, to which the document does not pay particular attention, are mainly level of the part of the deflector furthest from the anchor block.
  • the stay crosses downstream of the anchor a orifice which flares towards the running part, and which allows a angular deviation of the set of the shroud by taking up the bending forces along the length of the support zone of the stay in the hole (see for example GB-A-2,097,835).
  • An object of the present invention is to provide an anchoring system which limits the bending stresses of the cable in admissible values as soon as the exit of the anchorage. Another goal is to eventually allow provide a complementary external device to resume the efforts of bending due to variations in the trajectory of the cable.
  • the invention thus proposes a device for anchoring a cable of structure, comprising an anchor block traversed by orifices receiving each a strand of the cable and a locking means of said strand, a support piece for the anchor block, and means for guiding the strands between the block anchor and a running part of the cable, connected to the support piece and comprising for each strand of the cable an individual guide duct allowing angular deviation.
  • Each guide duct flares out direction of the current part of the cable.
  • the guide ducts present in direction of the anchor block a transversal distribution aligned with that of orifices of the anchor block.
  • the overall design of the anchor is greatly simplified by combining directly the guide means to the anchoring device.
  • the strands of the cable are guided individually, so that the inertia of the flexing element is significantly lower than the overall inertia of the cable. This results in filtering effective bending moments at the anchor block, even if the distance between the anchor block and the guide means is relatively low.
  • the individual guidance of the strands avoids the accumulation of transverse forces layers of strands on each other.
  • each guide duct flares in the direction of the current portion of the cable with a substantially constant radius of curvature in a plane passing through the axis of said duct
  • the guide means comprise at least one guide member housed in a tube connected to the workpiece support, through which are formed the guide ducts of the strands.
  • the guide member may be located just behind the anchor block, or be spaced a certain distance from the anchor block. In the latter case, may provide that the strands of the cable are individually protected strands in the current part, the individual protection of each strand being interrupted in a chamber between the guide member and the block anchoring, with sealing means placed between said chamber and the guiding member to form a tight separation between the chamber and the current part of the cable and contain a filling product and protection injected inside the chamber.
  • the device includes possibly a second guide member located between the anchor block and the sealing means.
  • the guide member may be of a rigid or deformable material. In the latter case, it is advantageous to leave a game, in the direction of part of the cable, between the circumference of the guide member and the tube in which it is housed, in order to allow an angular deflection of all the strands of the cable by deformation of the material of the guide.
  • the shape of this game is optimized to provide a curvature regular.
  • the game can result of a flare of the inside of the tube towards the part current of the cable, according to a substantially constant radius of curvature in a plane passing through the axis of the tube.
  • the play can result from a narrowing of the periphery of the organ in the direction of the running part of the cable, according to a radius of curvature substantially constant in a plane passing through the axis of the tube.
  • the game results in part from a narrowing of the periphery of the guide member towards the running part of the cable, and in part of a flare of the inner face of the tube towards the part current of the cable.
  • the deformable guide member has a viscosity, to provide damping of the cable when it oscillates.
  • This viscosity may be intrinsic to the deformable material of the organ, and / or result from a viscous substance contained in cavities in this organ.
  • the deformable guide member may comprise, between the ducts of guidance, decreasing inertia inserts towards the running part of the cable, which allows to control the curvature experienced by the cable through the organ.
  • the tube in which is housed the guide member deformable can have a decreasing inertia towards the part current of the cable.
  • An anchored stay using one of the devices described hereafter example is constituted by a bundle of strands 1 of which only one is drawn in the example considered here, the strands 1 are of the type individually protected: the assembly of stranded metal wires is embedded a product protecting against corrosion (for example a grease) and contained in an individual sheath 2 made of plastic (for example a high density polyethylene (HDPE)).
  • a product protecting against corrosion for example a grease
  • an individual sheath 2 made of plastic for example a high density polyethylene (HDPE)
  • the anchoring device comprises an anchor block 3 applied against a support piece 4 along a surface substantially perpendicular to the general direction of the stay.
  • the support piece 4 is applied, as opposed to the anchoring block 3 against the structural element to which the guy is subjected.
  • the anchoring block 3 is traversed by orifices 5 which have a frustoconical profile which flares towards the face of the block opposite to the support piece 4.
  • Each of the orifices 5 receives a strand 1 and a frustoconical jaw 6 which entrains the strand in the hole.
  • the individual protection of each strand in the current part is interrupted in a chamber 7 located behind the anchor block 3.
  • the jaws 6 directly grip the metal wires of the strands.
  • a filler eg a petroleum wax, a grease or a resin
  • the end of the chamber 7 opposite the block anchor 3 is closed by a sealing device 8 which seals around each sheathed strand 1 and at the inner face of the tube cylindrical 10 which delimits the chamber 7.
  • the sealing device 8 can in particular be of gland type, as described in the application EP-A-0 323 285.
  • a deviating member 11 brings together the strands 1 in formation more compact than in the anchoring, in order to minimize the overall cross section of the stay in the current area. he there is therefore a slight angular convergence of the strands 1 of the anchoring device towards the deflection device 11.
  • the anchoring device shown in FIG. guide 12 housed inside the aforementioned tube 10.
  • This tube 10 is connected to the support piece 4. It can for example be in one piece with this piece 4, as shown, or with parts 4 and 3, or attached to a clevis anchor.
  • the guide member 12 is constituted by a rigid cylindrical block (for example in HDPE) inserted substantially without play in the tube 10. Individual conduits 13 are formed in this block 12 to let pass and guide each of the strands 1.
  • the conduits 13 are circular with a diameter corresponding to that of the strands individually protected 1, and their transversal distribution is the same as that of the orifices 5 in the anchoring block 3.
  • each guide 13 In the direction of the current part of the stay, each guide 13, whose general shape is of revolution, flares out according to a profile which, in a plane passing through the axis of the duct, has a radius of curvature constant R.
  • This curvature allows the angular deviation of the strand towards the organ deviator 11, and further authorizes global flexion movements of the guy.
  • the bending moments are taken up by the guide member 12 on the length of the zone where the strand 1 is in contact with the wall of its conduit
  • the organ of guide 15, 17 is of a deformable material such as "Neoprene".
  • This material can advantageously have viscoelastic properties in order to participate in the damping of the vibrations of the cable, the viscosity providing a dissipation of vibratory energy.
  • the conduits 16 formed for the strands in the guide member of deformable material 15, 17 flare towards the running part of the stay according to a radius of curvature R 2 which may be greater than the radius R of the embodiment according to FIG. FIG. 1.
  • This radius R 2 is determined as a function of the angular deviation due to the convergence of the strands towards the deflection member 11.
  • this angular deflection can correspond to a tangent of the order of 2% , the radius R 2 and the axial length L of the guide member being then chosen so that the half-angle of the mouth of the conduit 16 to the current portion of the stay has a tangent slightly greater than 2%.
  • a game J is present between the inner face of the tube 10 and the periphery of the guide member 15, 17 in the direction of the running part of the stay, all along the circumference of the organ 15, 17. With this game J, the material of the organ 15, 17 can be deform globally by following the bending movements of the stay.
  • the clearance J is preferably defined by a curvature of constant radius R 1 (in a radial plane passing through the axis of the tube 10) at the interface between the periphery of the "Neoprene" guiding member and the inner face of the tube 10.
  • This radius R 1 is determined, along the length L, as a function of the extent of the flexions to which the stay can be subjected.
  • R 3 is defined by a combination of R 1 and R 2 , such that R 3 ⁇ R 1 and R 3 ⁇ R 2 .
  • This radius R 3 can be of the same order as the radius R of FIG.
  • the curvature of radius R 1 is formed on the internal face of revolution of the tube 10, which flares towards the current portion of the stay, the periphery of the guide member 15 being cylindrical.
  • the curvature of radius R 1 is defined on the periphery of revolution of the guide member of deformable material 17, which narrows towards the current portion of the stay, the inner face of the tube 10 being cylindrical.
  • the set J results from a combination of curvatures of the inner face of the tube 10 (Figure 2) and the periphery of the member of deformable material (Figure 3).
  • the guide means comprise two members of deformable material, one placed between the anchoring block 3 and the sealing device 8, and the other 22 placed beyond the sealing device 8.
  • Each guide duct receiving a strand then comprises a cylindrical portion 21, of diameter corresponding to that of the strand, formed in the member 20, and a portion 23 formed in the member 22 and which flares out towards the running part of the stay according to the radius of curvature R 2 .
  • the member 20 is housed in the cylindrical tube 10, which holds it in place on the side of the block 3. To the current part, the periphery of the member 20 tightens along the radius of curvature R 1 to resume the movements of bending.
  • the set J is created according to the same mode as in Figure 3, by curving inwards the periphery deformable organ.
  • the game J could be created, in wholly or in part, by an outward curvature (according to Figure 2) of the inner face of the tube 10 to the right of the member 20 adjacent to the anchor block.
  • the tube connected to the part support 4 comprises two successive portions 10a, 10b.
  • the portion 10a cylindrical, contains the sealing device.
  • Portion 10b mounted cantilevered, contains the deformable guide member 15 which may have a constitution similar to that of figure 2.
  • the inertia of this portion 10b decreases towards the current portion of the stay, which allows a flexion progressive cable and guide member.
  • the decreasing inertia is realized by decreasing the thickness of the wall of the tube portion 10b (on could also play on the properties of the material).
  • the progressive bending of the cable and the deformable guide member 25 results from the decreasing inertia, direction of the current portion of the stay, inserts 27 placed in the material deformable between the guide ducts 26.
  • inserts 27 are for example metal and tapered shape. They can be connected to a common support located on the side of the member 25 directed towards the anchor block.
