Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Bridge Seismic trip device of the present utility model comprises sleeve 11, spring steel plate 23 and shock absorption buckling tenon.Shock absorption buckling tenon has bottom cone post structure section 20a and Upper rectangular constructs section 20b, and the top of Upper rectangular structure section 20b and bottom cone post structure section 20a is arranged in the rectangular inner cavity of sleeve 11.Cone post structure both sides, section 20a top, bottom are arranged in semi-moon shaped spring steel plate 23 direction across bridge, its upper end is stuck in Upper rectangular structure section 20b and the intersection that post constructs section 20a is bored in bottom, and lower end is stuck in sleeve 11 rectangular inner cavity bottom surface and bottom and bores post and construct between section 20a.With reference to Fig. 3 and Fig. 4, sleeve 11 sidewall is fixedly connected with bed plate 10, and is connected with beam body 30 lateral sidewalls by high-strength bolt assembly.The lower end of bottom cone post structure section 20a is fixedly connected with mounting seat 21, and is fixedly connected with pier stud 31 by high-strength bolt assembly.See figures.1.and.2, between the inwall that the sidewall of the Upper rectangular structure section 20b of described shock absorption buckling tenon, end face are corresponding with sleeve 11 rectangular inner cavity, be provided with cushion 12.
With reference to Fig. 3 and Fig. 4, shock absorption buckling tenon is by being fixed on sleeve on beam body 30 11 and being fixed on pier stud 31, under impact load, the thrust stiffness under vertical, horizontal, longitudinal normal operating condition of beam body can be met, to meet safety, the comfort index requirement of bridge driving.Under rarely occurred earthquake, shock absorption buckling tenon to be dissipated seismic energy by self-deformation, and by shock absorption buckling tenon is vertically arranged to iso-intensity curve, rationally, effectively can control shock absorption buckling tenon dissipation energy, ensures the safety of total.
With reference to Fig. 1, the semilune spring steel plate 23 being arranged at shock absorption buckling tenon both sides is made up of the soft rigid material of high ductility, under vertical, lateral seismic active force or other impact load, play power consumption.Under Impact Load, bridge superstructure and sleeve 11 are fixed together and extrude semilune spring steel plate 23, and spring steel plate 23 plays power consumption effect by deformation.While both sides semilune spring steel plate 23 is extruded when bearing the action of horizontal lateral of common earthquake and deforms, also vertical distortion can be produced, lateral strain can consume transverse load energy, vertical deformation can provide a vertical supporting power to sleeve 11 and shock absorption buckling tenon, improve overall vertical rigidity, realize the function of laterally power consumption and vertical anti-pulling.Be that both sides semilune spring steel plate 23 also can produce horizontal strain, and vertical strain can consume vertical load energy, and lateral deformation can improve lateral stiffness when this device bears vertical earthquake loading, play the effect of vertical damping power consumption.
See figures.1.and.2, cushion 12 generally can adopt macromolecule damping rubber material, the Upper rectangular being arranged on sleeve 11 and shock absorption buckling tenon constructs between section 20b, absorbed by the deformation of damping rubber and consume portion of energy, alleviate the impact between shock absorption buckling tenon and sleeve 11, thus be conducive to the shock resistance improving overall bridge construction.
With reference to Fig. 2, for ease of manufacturing and conveniently installing and change shock absorption buckling tenon, described sleeve 11 has the front opening communicated with its rectangular inner cavity, and the cover plate 13 can closing this front opening is fixedly connected on bed plate 10 by high-strength bolt assembly.
The above principle more of the present utility model that just explain through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
