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 done only for pro forma but not substantial equivalent transformation all should be considered as the technical solution of the utility model category.
Embodiment 1: 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 authorities of a side hollow out the seat chamber 30 that is formed with a ring-type, in this chamber 30, set gradually first buffer board 3, intermediate plate 4, wearing plate 5 and second buffer board 6 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 30, offer the 5th bolt hole 29 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 29, the 5th bolt hole 28 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 33 and spring 32 are nested with on the shearing bolt 7 successively, be rotated with the connection screw thread 27 of nut 31 with shearing bolt 7 ends, aforesaid packing ring 33 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, the 5th bolt hole 29,28 substantially.In bridge construction process, when the utility model pull bar shock mount 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 33 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 four groups of pull bars, because four groups of pull bars 23 are all identical with the bind mode of upper base plate 2, following seat board 1, therefore select one and describes.In the present embodiment, with regard to one group of pull bar 23, it is made up of two rod irons that connect by the 3rd ball-type hinge 24.Every group of pull bar two ends connect with overhead gage 8 and following seat board 1 mutually by first ball-type hinge, 13, second ball-type hinge 25 respectively.First ball-type hinge, 13, second ball-type hinge 25 is linked to be integral body with overhead gage 8, following seat board 1 respectively by welding, and the 3rd ball-type hinge 24 should be opened two mouthfuls, respectively by two groups of pull bars.High damping material is all filled in ball-type hinge inside, and damped coefficient is selected by actual the requirement.Aforesaid overhead gage 8 is anchored on the upper base plate 2, and its height should be able to guarantee can suitable contacting be arranged with following seat board 1 when bearing is shifted, so that can be successful spacing.The 3rd buffer board is bonded in the overhead gage inboard with the organic polymer binding material.Lower baffle plate is anchored in down on the seat board, and the distance of its width and distance second ball-type hinge should be able to guarantee that rod iron upwards rotates and be no more than certain angle, so that vertical spacing.
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 pull bar shock mount that makes the utility model structure shows as the form of fixed bearing, i.e. the horizontal movement that is retrained between upper and lower seat board 2, the upper base plate 1 by shearing bolt 7.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 cut off, 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, when bearing surpasses certain design load to a lateral movement shift value, this side bearing overhead gage contacts beginning with following seat board spacing, and opposite side pull bar 23 bears pulling force, and then the overhead gage participation of drive homonymy is stressed, makes that promptly the overhead gage associating of bearing both sides is spacing, avoid the monolateral effect of being cut that withstands shocks of steel shoe, strengthened shock resistance.
Shearing bolt 7 cancellations with above-mentioned fixed pull bar shock mount, then becoming multidirectional active type draws and cuts the interlock shock mount, if adding side guide then becomes unidirectional active type and draws and cut the interlock shock mount, when earthquake takes place, these three kinds of bearings can act synergistically, and earthquake energy is also controlled the bridge horizontal movement.
