The specific embodiment
For the auditor that the makes Patent Office especially public can be expressly understood technical spirit of the present utility model and beneficial effect more, the applicant general elaborates in conjunction with the accompanying drawings in the mode of embodiment below, but to the description of embodiment all is not restriction to the utility model scheme, any according to the utility model design made only for pro forma but not substantial equivalent transformation all should be considered as the technical solution of the utility model category.
Ask for an interview Fig. 1 and Fig. 2, the following seat board 1 of a rectangle is fixed with the bridge pier of bridge under user mode, respectively offers one the 7th bolt hole 12 in four bights of following seat board 1 for this reason, will descend seat board 1 and the built-in fitting on the bridge pier to fix with first bolt 15.Following seat board 1 towards on the central design of a side pedestal 11 of one ring-type is arranged, pedestal 11 has a chamber 29, sets gradually first buffer board 3, intermediate plate 4, wearing plate 5 and second buffer board 6 in this chamber 29 from bottom to up.First buffer board 3 is a rubber tile, and intermediate plate 4 is a steel plate, and wearing plate 5 is polyfluortetraethylene plate or high molecular abrasion-proof plate, and second buffer board 6 is a corrosion resistant plate.Wherein, be provided with sealing ring 18 between first buffer board 3 and intermediate plate 4, and intermediate plate 4 is formed with a slide plate chamber 10, wearing plate 5 is positioned at this slide plate chamber 10.
The upper base plate 2 of one rectangle, fixing with the girder bottom surface (the beam body that also claims bridge) of bridge under user mode, respectively offer one the 8th bolt hole 22 in four bights of upper base plate 2 for this reason, with second bolt 16 upper base plate 2 and girder bottom surface are fixed.
Illustrate jointly by Fig. 1 and Fig. 2, central authorities at following seat board 1 have one first bolt hole 14 (Fig. 2 shows), central authorities at first buffer board 3 offer one second bolt hole 17 (Fig. 2 shows), central authorities at intermediate plate 4 offer one the 3rd bolt hole 20, central authorities at wearing plate 5 offer one the 4th bolt hole 28, offer the 5th bolt hole 27 and offer the 6th bolt hole 21, aforesaid first bolt hole 14 in the central authorities of second buffer board 6 in the central authorities of upper base plate 2, second bolt hole 17, the 3rd bolt hole 20, the 4th bolt hole 28, the 5th bolt hole 27 and the 6th bolt hole 21 all correspond to each other.Shearing bolt 7 as one of technical essential of the present utility model is located on aforesaid first to the 6th bolt hole, wherein, the upper end of shearing bolt 7 is leaning out the 6th bolt hole 21 back dislocate automatically with pair of bolts one of them bolt in the devices 9 dislocate automatically device 9 and its connection, specifically: packing ring 32 and spring 31 are nested with on the shearing bolt 7 successively, be rotated with the connection screw thread 26 of nut 30 with shearing bolt 7 ends, aforesaid packing ring 32 contacts with upper base plate 2; The lower end of shearing bolt 7 is leaning out first bolt hole 14 back with another bolt dislocate automatically device 9 and its connection, and bind mode specifically also can be fully understood by the signal of Fig. 2 as the description to the connection of the upper end of shearing bolt 7; The middle part of shearing bolt 7 with the constriction state constitute a sheared edge 19, the position of sheared edge 19 is corresponding with aforesaid the 4th bolt hole 28, the 5th bolt hole 27 substantially.In bridge construction process, when the utility model inhaul cable damping support saddle is installed, preferred scheme is respectively to preset on bridge pier and pontic (the beam body of bridge) corresponding to bolt dislocate the automatically pit or the hole of device 9, so that after sheared edge 19 is cut off, spring in aforesaid pit or the hole by the effect of the restoring force of spring 31 shearing bolt 7 with fracture.
Please continue to see Fig. 1 and Fig. 2, another technical essential of the technical solution of the utility model is to adopt two groups of drag-lines, because two groups of drag-lines 8 are all identical with the bind mode of upper base plate 2, therefore select one and describes.In the present embodiment, with regard to one group of drag-line 8, its radical is three, and is for example few to two certainly according to concrete situation increase and decrease, 19 of as many as.Be furnished with one second positioning cap 25 at the two ends of every drag-line 8, outside the drag-line 8 that assembles by three drag-lines 8, be provided with drag-line restoring spring 24, to guarantee under normal operating condition, making drag-line 8 be in the equilbrium position.Aforesaid positioning cap 25 is to pass the back, the second drag-line hole 23 that is opened on the upper base plate 2 with construction installation hydraulic pressure press-connection machine or similarly install crimping and be linked on the drag-line 8 for example at drag-line 8.Because the quantity of one group of drag-line 8 is three, therefore, the quantity that is opened in second, the first drag- line hole 23,13 on upper base plate 2 and the following seat board 1 respectively is three.With three the second drag-line holes 23 that are opened on the upper base plate 2 is example, around the 22 curved arrangements of the 8th bolt hole.Aforesaid drag-line 8 is made of steel strand, but also can adopt high-tensile steel wires, carbon fiber etc., the aforesaid first drag-line hole, the second drag-line hole 23 are the reducing hole, the first drag-line hole 13 on the following seat board 1 is an example, the diameter of bottom is big and upper part diameter 2 is little, and for example, the aperture of the upper end in the second drag-line hole 23 is bigger than the aperture of lower end on the upper base plate 2, so that the positioning cap 25 of drag-line 8 is placed in the second drag-line hole 23 well.Drag-line leads by drag-line guiding device 10 in 13 backs, the first drag-line hole of passing lower support plate, is passed by the first drag-line hole 13 again, is anchored in 23 places, the second drag-line hole.
Under the normal condition before earthquake takes place, because the effect of shearing bolt 7, upper base plate 2, following seat board 1 are coupled as one, thereby the inhaul cable damping support saddle that makes the utility model structure shows as the form of fixed bearing, promptly by shearing bolt 7 constraint upper base plates 2, the horizontal movement between the seat board 1 down.Yet, when earthquake takes place, aforesaid horizontal force is during greater than the shear strength of the sheared edge 19 of shearing bolt 7, shearing bolt 7 is just fractureed, and taken off by the bolt at two ends device 9 bullets of dislocating automatically, as seen, shearing bolt 7 plays the effect of two aspects, the one, can consume the portion of energy that causes upper base plate 2, following seat board 1 horizontal movement that earthquake causes, thus the protection bridge; The 2nd, because shearing bolt 7 disconnects, to have removed upper base plate 2, the constraint of seat board 1 down, the character that makes bearing is multidirectional freely movable bearing transition from previous fixed bearing.Certainly, the power of the sheared edge 19 tolerance fractures of shearing bolt 7 obtains by designing and calculating according to mechanics principle.In addition, after shearing bolt 7 disconnects, make the relative displacement between upper base plate 2, the following seat board 1 obtain buffer limit by drag-line 8, and after earthquake disappears, ensure that by drag-line restoring spring 24 upper base plate 2, following seat board 1 reset, and are fully protected the safety of bridge.
Shearing bolt 7 cancellations with above-mentioned fixed inhaul cable damping support saddle, then become multidirectional active type inhaul cable damping support saddle, then become unidirectional active type inhaul cable damping support saddle if add side guide, when earthquake takes place, these three kinds of bearings can act synergistically, earthquake energy and control the bridge horizontal movement and the shake after reset.
