The utility model discloses not only can keep apart the horizontal earthquake effect to has great vertical rigidity: horizontal earthquake effect down, the cross platform can be in the frame free motion, the tensile device does not influence isolation bearing shock insulation horizontal earthquake and acts on, under super large seismic action, isolation bearing can produce great vertical pulling force, takes place vertical lifting from, and the cross platform received the restraint of the roof beam of frame this moment, had restricted support vertical motion, and protection isolation bearing is pulled open badly.
Description
Technical field
This utility model belongs to field of civil engineering, is specifically related to a kind of tensile shock isolation device.
Background technology
Base Isolation Technology is by arranging earthquake isolating equipment in structural base, the natural vibration period of buttress in prolongation, reduces the horizontal earthquake action of the upper buttress of input, reaches intended damping requirement.Earthquake isolating equipment the most frequently used at present is laminated rubber bases.Laminated rubber bases is to be formed through sulfurization compacting by steel plate and rubber, and experiment finds, after laminated rubber bases tension, inner rubber is subject to lift-off and produces many emptying apertures, and when tension reaches 1.5 ~ 5.0Mpa, the extensional rigidity of bearing can sharply decline.And when recompression after bearing tension, the pressurized Stiffness Drop of bearing is low to moderate about the 1/4 of former rigidity.Relatively macrolesion can be produced after bearing tension is described, have a strong impact on the mechanical property of bearing.This feature of laminated rubber bases, constrains seismic isolation technology application in high-level structure.Because the tilting moment caused in Vertical Earthquake Loads and the horizontal earthquake action of skyscraper is all relatively big, carrying out shock insulation according to laminated rubber bases, bearing is likely to occur that pulling force destroys.Therefore, seismic isolation technology will extending to skyscraper, the tensile property solving bearing is a very crucial problem.
Utility model content
This utility model provides a kind of tensile shock isolation device, while ensureing horizontal seismic isolation effect, has again bigger vertical tensile property, protects shock isolating pedestal tensile failure.
For solving the problems referred to above, the technical scheme that this utility model adopts is:
. a kind of tensile shock isolation device, including shock isolating pedestal, the upper junction plate of described shock isolating pedestal and the lower surface of cross platform are affixed, and the upper surface of cross platform is close in the lower surface of the beam of framework, and the two ends of pull bar are respectively perpendicular the outer end place on the edge of a wing being connected to superstructure beam, cross platform.
Described framework is made up of pillar and beam；Described pillar is fixed on the ground of shock isolating pedestal surrounding, is connected as one by beam between each pillar, and the upper surface of cross platform is close in the lower surface of this beam.
Described cross platform by truss and be fixed in the upper flat plate of truss upper and lower side, lower flat board is constituted.
Described shock isolating pedestal is laminated rubber bases, sliding bearing or friction pendulum support.
This utility model is possible not only to level of isolation geological process, and has bigger vertical rigidity: under horizontal earthquake action, cross platform can freely-movable in framework, tensile device does not affect shock isolating pedestal shock insulation horizontal earthquake action；Under super large geological process, shock isolating pedestal can produce bigger vertical tension, and vertical lift-off occurs, and now cross platform is subject to the constraint of the beam of framework, limits bearing vertical motion, protects shock isolating pedestal tensile failure.
This utility model simple structure, concise production process, to draw materials conveniently, tensile property is superior, and product quality is easily controllable, it is simple to marketing.
