Description of drawings
Fig. 1 is an enforcement assembling assumption diagram of the present invention.
Fig. 2 is the sectional view of Fig. 1.
The specific embodiment
For the auditor that the makes Patent Office especially public can be expressly understood technical spirit of the present invention 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 present invention program, any according to the present invention's design done only for pro forma but not substantial equivalent transformation all should be considered as technical scheme category of the present invention.
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 121.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 111, sets gradually first buffer board 3, intermediate plate 4, wearing plate 5 and second buffer board 6 in this chamber 111 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 32 between first buffer board 3 and intermediate plate 4, and intermediate plate 4 is formed with a slide plate chamber 42, wearing plate 5 is positioned at this slide plate chamber 42.
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 21 in four bights of upper base plate 2 for this reason, with second bolt 221 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 buffer board 3 offer one second bolt hole 31 (Fig. 2 shows), central authorities at intermediate plate 4 offer one the 3rd bolt hole 41, central authorities at wearing plate 5 offer one the 4th bolt hole 51, offer the 5th bolt hole 61 and offer the 6th bolt hole 21 in the central authorities of upper base plate 2 in the central authorities of second buffer board 6, aforesaid the first, second, third, fourth, the 5th and the 6th bolt hole 14,31,41,51,61,21 all corresponds to each other.Shearing bolt 7 as one of technical essential of the present invention 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 93 and spring 92 are nested with on the shearing bolt 7 successively, be rotated with the connection screw thread 72 of nut 91 with shearing bolt 7 ends, aforesaid packing ring 93 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 71, the position of sheared edge 72 is corresponding with aforesaid the 4th, the 5th bolt hole 51,61 substantially.In bridge construction process, when inhaul cable damping support saddle of the present invention 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 71 is cut off, spring in aforesaid pit or the hole by the effect of the restoring force of spring 92 shearing bolt 7 with fracture.
Please continue to see Fig. 1 and Fig. 2, another technical essential of technical scheme of the present invention is to adopt four groups of drag-lines, because four groups of drag-lines 8 are all identical with the bind mode of upper and lower seat board 2,1, so the applicant selects 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 first positioning cap 82 at an end of every drag-line 8, the other end respectively is furnished with one second positioning cap 83, is provided with drag-line restoring spring 81 outside the drag-line 8 that is assembled by three drag-lines 8, to guarantee making drag-line 8 be in the equilbrium position under normal operating condition.Aforesaid first positioning cap 82 is to pass 13 backs, the first drag-line hole that are opened on the following seat board 1 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, and second positioning cap 83 is with example.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, and around the 22 curved arrangements of the 8th bolt hole, the first drag-line hole 13 on the following seat board 1 is circular arc around the 7th bolt hole 12 and arranges with example.Aforesaid drag-line 8 is made of steel strand, but also can adopt high-tensile steel wires or carbon fiber etc., aforesaid first, second drag- line hole 13,23 is 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 first, second positioning cap 82,83 of drag-line 8 is placed in first, second drag- line hole 13,23 well.
Under the normal condition before earthquake takes place, because the effect of shearing bolt 7, upper and lower seat board 2,1 is coupled as one, thereby makes the inhaul cable damping support saddle of structure of the present invention show as the form of fixed bearing, promptly by the horizontal movement between the upper and lower seat board 2,1 of shearing bolt 7 constraints.Yet, when earthquake takes place, aforesaid horizontal force is during greater than the shear strength of the sheared edge 7 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 and lower seat board 2,1 horizontal movement that earthquake causes, thus the protection bridge; The 2nd, because shearing bolt 7 disconnects, removed constraint to upper and lower seat board 2,1, the character that makes bearing is multidirectional freely movable bearing transition from previous fixed bearing.Certainly, the power of the sheared edge 71 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 the upper and lower seat board 2,1 obtain buffer limit, and after earthquake disappears, ensure that by drag-line restoring spring 81 upper and lower seat board 2,1 resets, the safety of bridge is fully protected by drag-line 8.
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.
