Definitions

  • the present invention relates to a method of overblocking at least one strand in an anchor block and to a system for overblocking at least one strand in an anchor block.
  • the invention relates to a method of overblocking at least one strand in an anchoring block by radial clamping of the strand by a frustoconical jaw which surrounds said strand and which is housed in a frustoconical recess of complementary shape formed in the anchor block.
  • a strand is constituted by a wire or a plurality of twisted son intended to be stretched in particular to ensure the prestressing of a concrete body or the suspension of a structure such as a bridge (stay).
  • the blocking or prior clamping of the strand before its blocking in the anchor block is provided by the pulling of the cable itself and at least partly by applying an axial thrust on a large base of said jaw.
  • This axial thrust makes it possible to ensure cone-cone clamping of said jaw with the anchor block, thereby causing radial tightening of the strand.
  • a security operation called an overlocking operation, makes it possible to guarantee that the bit is held around the strand during the life of the structure on which said strand is stretched. .
  • This blocking operation is currently performed by means of hammer strikes carried directly on the large base of said jaw to move a few millimeters in its housing to ensure a radial prestressing on the strand. Nevertheless, this overblocking operation carried out by an operator striking with hammer on the jaw does not provide an accurate guarantee that the displacement of the anchor jaw in its housing has been sufficient for said jaw to find a so-called final position that is say a position that said jaw is intended to find during the maximum load supported by said strand.
  • the present invention is intended in particular to improve these overlocking methods in particular so that the operator is sure that said anchor jaw has reached its position of overlocking.
  • FIG. 1 represents an overblocking system 1 adapted to overlock at least one strand 2 in an anchoring block 3 by radial clamping of the strand by an anchoring jaw 4 which surrounds said strand 2 and which is housed in a frustoconical recess 5 made in the anchor block 3.
  • the strand 2 may be composed of a single strand or a plurality of twisted strands.
  • the anchoring jaw 4 may be formed by a slotted anchor jaw or by a plurality of two or so substantially semi-shaped keys 4a, 4b, for example. cylindrical and frustoconical.
  • the widest end of the anchoring jaw 4 is axially projecting on the face 3a of the anchoring block 3.
  • the free end of the strand 2 also extends beyond the widest portion of the jaw. anchorage 4.
  • the radial clamping of the strand 2 by the anchoring jaw 4 is ensured by a wedge effect by urging this anchoring jaw 4 and thus the keys 4a, 4b to the axial depression in the frustoconical recess 5.
  • the axial stress can be generated by the same tension of the strand 2 because of the friction between the strand and the inner face of the anchoring jaw 4, or by pressing axially this anchoring jaw 4 in the recess 5 while the tension of the strand 2 is zero.
  • a security operation makes it possible to guarantee the holding of the anchoring jaw 4 and thus of the keys 4a, 4b during the life of the the work.
  • This overlock makes it possible to guarantee radial prestressing on the strand 2 by depressing the anchoring jaw 4, this preload on the strand 2 substantially corresponding to the final position of the keys 4a, 4b, that is to say the position that they would find during the maximum loading to bear by the strand 2.
  • the blocking system comprises, as can be seen in FIG. 1, an explosive cartridge device 6 as well as a force transmission device 7 directly disposed between the explosive cartridge device. 6 and the anchoring jaw 4 previously pressed into the frustoconical recess 5 of the anchoring block 3.
  • the explosive cartridge device 6 may for example be formed by an automatic pistol with an automatic or manually replaceable explosive cartridge, which comprises (FIG. 2) a counterweight 8 intended to be propelled during the explosion of the explosive cartridge.
  • this device with an explosive cartridge 6 can be formed by an automatic cartridge gun marketed by HILTI, in particular under the reference DXA 40.
  • the force transmission device 7 is for its part intended to cooperate with the flyweight 8 of the explosive cartridge device 6 to allow the explosion of this explosive cartridge propulsion of the weight against the force transmission device which in turn press against the frustoconical jaw 4 to push it into a position of overlocking in the frustoconical recess 5 of the anchor block 3.
  • this force transmission device 7 comprises a body 9 formed by a first housing 10 and a second housing 11 which delimit between them an inner chamber 12.
  • This inner chamber 12 of the body 9 extends between a first orifice 13 directly on the first housing 10 and a second orifice 14 directly on the second housing 11.
  • the first port 13 is directly connected to a nozzle 6a in which is slidably housed the weight 8 of the explosive cartridge device 6.
  • This 6a end piece may form a constituent element of the explosive cartridge device 6 or may form a constituent element of the force transmission device 7.
  • This nozzle 6a is directly fixedly mounted in the orifice 13 of the first housing 10 for example by means of a pin 15 which passes through the casing 10 to cooperate with the end piece 6a so as to secure them together.
  • the second casing 11 has a bottom 11a on which the orifice 14 is made, and from which extends an annular wall 11b intended to cooperate with an annular wall 10a of the first casing 10 to form the inner chamber 12.
  • the first housing 10 and the second housing 11 are fixed together by any appropriate means and in particular for example by screwing and / or by means of a pin 16.
  • the force transmission device 7 also comprises a percussion member 17 which is substantially in the form of an elongate shaft which comprises, on the one hand, a first portion 18 housed in the inner chamber 12 of the body 9 and which has a diameter greater than the second orifice 14 of the housing 11, and secondly, a second hollow cylindrical portion 19 which is integral with the first portion 18 and which is slidably mounted in the second orifice 14 of the housing 11.
  • This second cylindrical portion 19 has a free end 19a intended to bear against the widest part of the keys 4a, 4b forming the anchoring jaw 4 while surrounding the end of the strand 2 which projects beyond said keys 4a, 4b.
  • the first portion 18 of the percussion member 17 also comprises a cylindrical annular wall 18a which extends towards the housing 10 and which surrounds a compression spring 20 directly interposed between the housing 10 and the first portion 18 of the body 17.
  • the first portion 18 of the percussion member 17 also comprises a centralizer 21 of the spring 20 which is arranged opposite the weight 8.
  • the damping elements 22, 23 are arranged on both sides. other of the inner chamber 12 of the body 9 so as to damp the displacement of the first portion 18 of the percussion member 17 inside the body 9.
  • This percussion member 17 then automatically transmits the shock produced by the weight 8 to the keys 4a, 4b of the anchoring jaw 4 so as to bring to a position of overlock which corresponds to a position that the anchor jaw would have found during the maximum load tolerated by the strand 2, thereby ensuring a radial prestressing of the strand 2.
  • This overblocking operation thus makes it possible to dissociate the resistance of the strand in the anchoring and the tension of the strand, which can be advantageous in the case where the tension of the strand 2 can be greatly diminished or even canceled during the service of the strand.
  • strand such a situation may occur for example when receiving a shock by a suspension bridge strand, the shock may for example be caused by an earthquake, a tornado or the loss of control of a vehicle weight heavy.
  • the choice of the explosive cartridge and the percussion member 17 makes it possible to adapt and select the calibrated force transmitted to the anchoring jaw in order to fix it in its so-called overblocking position.
  • the dimensions of the weight and the organ of repercussion 17 may be chosen so as to avoid buckling or matting.
