Definitions

  • the present invention relates to a method of overblocking of at least one strand in an anchor block and a system for overblocking at least one strand in a block anchor.
  • the invention relates to a method for overblocking at least one strand in an anchor 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 made in the anchor block.
  • a strand is constituted by a wire or a plurality of twisted wires to be particularly with a view to ensuring the prestressing of a concrete body or the suspension of a structure such as a bridge (Stay).
  • the blocking or prior tightening of the strand before its overblocking in the anchor block is ensured by traction cable itself and at least partly by application an axial thrust on a large base of said jaw.
  • This axial thrust ensures cone-on-cone clamping said jaw with the anchor block thereby causing a radial clamping of the strand.
  • an operation of securing known as overblocking, ensures the holding the bit around the strand during the life of the work on which is stretched said strand.
  • This overblock operation is currently carried out by means of hammer blows carried directly on the big base of said jaw in order to move it on few millimeters in its housing to guarantee a radial prestress on the strand. Nevertheless, this overblocking operation performed by a striking operator with hammer on the bit does not guarantee accurately that moving the anchor jaw into its housing was sufficient for the said bit to find a so-called final position that is to say a position that said jaws is meant to find when loading maximum supported by said strand.
  • the present invention is intended in particular to perfecting these methods of overblocking in particular the operator is sure that said anchoring jaw has reaches its overblock position.
  • FIG. 1 represents an overclocking system 1 adapted to overlock at least one strand 2 in a block anchoring 3 by radial clamping of the strand by a jaw anchor 4 which surrounds said strand 2 and which is housed in a frustoconical recess 5 made in the anchoring block 3.
  • the strand 2 can be composed of a single strand or a plurality of twisted strands.
  • the anchoring jaw 4 can be formed by an anchor jaw slotted or by a plurality of keys 4a, 4b, for example two in number, of a semi-cylindrical shape and truncated.
  • the widest end of the anchor jaw 4 is axially protruding on the face 3a of the anchoring block 3.
  • the free end of the strand 2 also extends beyond the widest portion of the anchor jaw 4.
  • Radial clamping of the strand 2 by the anchoring jaw 4 is ensured by a wedge effect by soliciting this bit anchoring 4 and thus the keys 4a, 4b at the depression in the tapered recess. 5.
  • the axial stress can be generated by the tension of the strand 2 because of friction between this strand and the inner face of the anchoring jaws 4, or by pressing axially this bit 4 in the recess 5 while the tension of the strand 2 is zero.
  • overblocking makes it possible to guarantee the hold of the bit anchoring 4 and thus keys 4a, 4b during life of the book.
  • This overblocking makes it possible to guarantee radial prestressing on the strand 2 by depressing the bit 4, this preload on the strand 2 substantially corresponding to the final position of the keys 4a, 4b, i.e. the position they would find during the maximum load to bear by the strand 2.
  • the overlock system comprises, as can be seen in FIG. an explosive cartridge device 6 and a device transmission of effort 7 directly disposed between the explosive cartridge device 6 and the anchor jaw 4 previously pressed into the frustoconical recess 5 of the block anchor 3.
  • the explosive cartridge device 6 can by example be formed by an automatic cartridge gun explosive replaceable automatically or manually, and which includes (Figure 2) a flyweight 8 intended to be propelled during the explosion of the explosive cartridge.
  • this explosive cartridge device 6 can be formed by an automatic cartridge gun marketed by HILTI, particularly under the reference DXA 40.
  • the force transmission device 7 is to him for cooperating with the weight 8 of the device with an explosive cartridge 6 to allow during the explosion of this explosive cartridge a propulsion of the weight against the device of transmission of efforts which supports turn against the frustoconical jaw 4 in order to drive it in a position of overblocking 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 a room 12.
  • This inner chamber 12 of the body 9 extends between a first orifice 13 directly made on the first housing 10 and a second port 14 directly made on the second casing 11.
  • the first port 13 is directly connected to a tip 6a in which is housed slidably the weight 8 of the device to explosive cartridge 6.
  • This tip 6a can form an element constituent of the explosive cartridge device 6 or form a constituent element of the transmission device 7.
  • This tip 6a is directly mounted fixed in the orifice 13 of the first housing 10 for example by means of a pin 15 which passes right through the housing 10 for come cooperate with the tip 6a so as to secure them between them.
  • the second casing 11 has a bottom 11a on which is made the orifice 14, and from which extends an annular wall 11b intended to cooperate with an annular wall 10a of first housing 10 to form the inner chamber 12.
  • the first casing 10 and the second casing 11 are fixed between them by any appropriate means and in particular for example by screwing and / or by means of a pin 16.
  • the force transmission device 7 comprises also a percussion organ 17 that presents itself substantially in the form of an elongate tree that includes, on the one hand, a first portion 18 housed in the chamber inside 12 of the body 9 and which has a diameter greater than the second orifice 14 of the housing 11, and other part, a second hollow cylindrical portion 19 which is integral with the first portion 18 and which is mounted sliding 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 keys 4a, 4b forming the anchor jaw 4 while surrounding the end of strand 2 which protrudes beyond said keys 4a, 4b.
  • the first portion 18 of the percussion member 17 also comprises a wall cylindrical ring 18a which extends towards the casing 10 and surrounding a compression spring 20 directly interposed between the housing 10 and the first portion 18 of the percussion organ 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.
  • damping elements 22, 23 are arranged on either side of the inner chamber 12 of the body 9 so as to dampen the displacement of the first portion 18 of the percussion member 17 within the body 9.
  • the operator When an operator wants to unlock the bit anchor 4 in the frustoconical recess 5 of the anchor block 3 after having previously placed and depressed said bit 4 in the frustoconical recess 5, the operator first positions the overblocking system of such so that the free end 19a of the percussion member 17 come into contact with the keys 4a, 4b while surrounding the strand 2.
  • This implementation of the overclocking system 1 on the anchoring jaw 4 has the effect of bringing the annular wall 18a of the first portion 18 of the percussion member 17 in support against the damping element 23 and this to against the solicitation exercised by the compression 20.
  • the operator then only has to operate the explosive cartridge device 6 by igniting the explosion of said cartridge which can be an explosive cartridge releasing a gas at high pressure following the priming of the explosion to propel the weight 8 against the centralizer 21 of the first portion 18 of the organ percussion 17.
  • This percussion member 17 then transmits automatically the shock produced by the weight 8 to keys 4a, 4b of the anchoring jaw 4 so as to bring it in an overblock position that corresponds to a position that the anchor would have found during the maximum load tolerated by strand 2, ensuring thus a radial prestressing of the strand 2.
  • This overblocking operation therefore makes it possible to dissociate the resistance of the strand in the anchorage and the tension of the strand, which may be advantageous in the case where the 2 strand voltage can be greatly reduced or canceled, during the service of the strand itself: such a situation that may occur for example during the receiving a shock by a suspension bridge strand, the shock can be caused for example by an earthquake, a tornado or by the loss of control of a vehicle weight heavy.
  • the choice of the explosive cartridge and of the percussion organ 17 allows to adapt and choose the calibrated force transmitted to the anchor jaw in order to freeze it in its so-called overblocking position.
  • the dimensions of the weight and the organ of repercussion 17 can be chosen so as to avoid their buckling or matting.
