Detailed description of the invention
Further describe the technical solution of the utility model below, but described in claimed scope is not limited to.
A kind of prestress anchorage cable isolation mount mounting structure as shown in Figures 1 to 6, comprises isolation mount 1, steel strand 3; Described isolation mount 1 is evenly distributed with multiple through wires hole 2 around the center of circle of isolation mount 1, through wires hole 2 is circular port, the through wires hole 2 wherein having at least two positions relative is taper through wires hole 5, is provided with cone slope upper groove 9 in the middle part of the inclined-plane, cone slope of taper through wires hole 5; Described steel strand 3 are arranged through taper through wires hole 5, and in the space of steel strand 3 and taper through wires hole 5, wedging has wedge shape intermediate plate 7.
The top diameter of described taper through wires hole 5 is 1.2 times of end diameter, and end diameter is identical with the diameter of described through wires hole 2.
Be provided with cone slope upper groove 9 in described taper through wires hole 5, on described wedge shape intermediate plate 7, corresponding cone slope upper groove 9 is provided with semicircular flanges 8.
The radius of described cone slope upper groove 9 is 3mm.
Described wedge shape intermediate plate 7 is engineering plastics material, and profile is cone-shaped ring shape, annular diameters 1mm less of the diameter of described steel strand 3, and outer shroud is reducing, identical with taper through wires hole 5 reducing rule.
Semicircular flanges 8 radius in the middle part of described wedge shape intermediate plate 7 outer shroud is 2.7mm.
Described wedge shape intermediate plate 7 vertebral height 5mm larger than the thickness of described isolation mount 1, the respectively each 2.5mm of exposure isolation mount 1 upper and lower surface.
Described wedge shape intermediate plate 7 is 3 part compositions in each taper through wires hole 5, and wherein each partial arcs is 119 °.Thus, there is extruding simultaneously and cause wedge shape intermediate plate to destroy in reserved 1 ° of space between two wedge shape intermediate plate 7 annulus in radian direction when preventing 3 wedge shape intermediate plates 7 from installing.
According to the difference of anchor cable tonnage, the quantity of the radical of steel strand 3 and the through wires hole 2 of isolation mount 1 is also different, when anchor cable tonnage is larger, through wires hole 2 may arrange 2 ~ 3 rows along isolation mount 1 even circumferential, it should be noted that, taper through wires hole 5 must be arranged in from the genesis of isolation mount 1 the 1st round scope, adopts wedge shape intermediate plate 7 to be fixed to facilitate when anchor cable is assembled to isolation mount 1.
Said structure is installed in the following way:
1. steel strand 3 blanking, prepares isolation mount 1;
2. steel strand 3 and isolation mount 1 are assembled, during assembling, the number of times of the taper through wires hole 5 that the every bar steel strand 3 of anchor cable outmost turns pass approximates isolation mount 1 most edge through wires hole 2 and the quantity acquired results of taper through wires hole 5 sum divided by anchor cable outmost turns steel strand 3; Specifically, tackle steel strand 3 before reeving and isolation mount 1 is numbered, avoid a same steel strand 3 to continue to pass through the taper through wires hole 5 of several isolation mount 1.The taper through wires hole 5 of 2# isolation mount 2 worn by taper through wires hole 5, the 2# steel strand 3 that 1# isolation mount 1 worn by such as 1# steel strand 3, by that analogy.The object done like this is to ensure that every root steel strand 3 can be fixed through taper through wires hole 5, and every root steel strand 3 are roughly the same through the number of times of taper through wires hole 5, little as far as possible stress when affecting single steel strand pretension;
3. wedge shape intermediate plate 7 is assembled in isolation mount 1, fixing steel strand 3 and isolation mount 1;
4. assemble guiding cap, stringing ring, complete anchor cable establishment.
During lower rope, anchor cable hole wall will produce resistance to isolation mount 1, this drag direction is contrary with lower Suo Fangxiang, come off for isolation mount 1 is pullled from steel strand 3 by wall drag when avoiding lower rope, the one side that taper through wires hole 5 diameter is larger must face down Suo Fangxiang, such wedge shape intermediate plate 7 will form a conical flask stopper shape with steel strand 3, and conical flask jam-pack can press in taper through wires hole 5 by anchor cable wall drag, can effectively avoid isolation mount 1 to be pullled the possibility come off by anchor cable wall drag.
