Abstract
Passive type dynamic absorber bridge pier, effectively to improve the antiseismic and wind resisting stability of high pier of railway, highway.Comprise pier body (10), be provided with additional mass (20) outside pier body (10) upper portion side wall, additional mass (20) is connected with pier body (10) sidewall by elastic component (22).
Description
Technical field
The utility model relates to bridge, particularly a kind of passive type dynamic absorber bridge pier being applicable to railway, highway bridge.
Background technology
When China's mountain area railway construction and highway, run into the locations such as high mountain gorge unavoidably, inevitably occur high-pier and long-span bridge, particularly for the high ferro circuit of develop rapidly in recent years.Under the external load function such as earthquake, high wind, too high pier body easily produces and rocks, its bad stability, and then affects the stability of bridge construction and the riding comfort of operational vehicle thereon.Meanwhile, the vehicle that bridge runs can cause the vibration of beam body, and then by vibration passing in surrounding environment, cause secondary vibration noise pollution, therefore, for how, pier body carries out subtracting Vibration Absorbing System Design, with the research improving pier body stability with improve significant.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of passive type dynamic absorber bridge pier, effectively to improve the antiseismic and wind resisting stability of high pier of railway, highway.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Passive type dynamic absorber bridge pier of the present utility model, comprises pier body, it is characterized in that: be provided with additional mass outside described pier body upper portion side wall, additional mass is connected with pier body sidewall by elastic component.
The beneficial effects of the utility model are, adopt " spring-damping-quality " minor structure, the form of structure of suitable this minor structure of selection, kinetic parameter and the coupled relation with bridge pier, make the vibration phase of this minor structure contrary with the vibrational state of bridge pier under the external load functions such as train, earthquake, wind, vibrated by the Large travel range of additional mass, realize the object reducing the bridge pier vibration that external load causes, ensure the stability of bridge pier self; Structure is simple, be easy to construction, can introduce at the beginning of build bridge pier, for existing bridge pier improvement also more for convenience, do not affecting in the process that vehicle travels and can complete; Its structure is comparatively flexible, for different actual conditions, can adjust its structure and size.
Accompanying drawing explanation
This manual comprises following five width accompanying drawings:
Fig. 1 is the elevational schematic view of the utility model passive type dynamic absorber bridge pier;
Fig. 2 is the top view of the utility model passive type dynamic absorber bridge pier;
Fig. 3 is the elevational schematic view of the utility model passive type dynamic absorber bridge pier;
Fig. 4 is the elevational schematic view of the utility model passive type dynamic absorber bridge pier;
Fig. 5 is the top view of the utility model passive type dynamic absorber bridge pier.
Component shown in figure, toponym and corresponding mark: pier body 10, supporting member 11, additional mass 20, connecting elements 21, elastic component 22.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, passive type dynamic absorber bridge pier of the present utility model, comprises pier body 10, is provided with additional mass 20 outside described pier body 10 upper portion side wall, and additional mass 20 is connected with pier body 10 sidewall by elastic component 22.Additional mass 20 can be reinforced concrete coagulation block or the larger metallic object of density, and elastic component 22 can adopt by rubber, spring, colloid etc.The active force acted on additional mass 20 can be offset rapidly by the interaction between additional mass 20 and elastic component 22 within the specific limits, reaches effective absorbing and vibration damping.
The bridge pier of passive type dynamic absorber of the present utility model, adopt " spring-damping-quality " minor structure, the form of structure of suitable this minor structure of selection, kinetic parameter and the coupled relation with bridge pier, make the vibration phase of minor structure contrary with the vibrational state of pier body under the external load function such as earthquake, wind, vibrated by the Large travel range of additional mass 20, realize the object reducing external shock vibration component, ensure the stability of bridge pier self.
With reference to Fig. 1, described pier body 10 top is fixedly installed supporting member 11, and additional mass 20 is positioned at below supporting member 11, and is formed by connecting elements 21 and supporting member 11 and flexibly connect.When connecting elements 21 adopts rigid material, its upper and lower end is hinged with supporting member 11, additional mass 20 respectively.
See figures.1.and.2, described additional mass 20 can adopt annular construction member, is placed on outside pier body 10 perisporium, arranges multiple elastic component 22 uniformly at intervals along pier body 10 hoop.With reference to Fig. 3, when being applied to over-height pier, described supporting member 11, additional mass 20 be longitudinally interval setting on pier body 10 top.
With reference to Fig. 4 and Fig. 5, described additional mass 20 also can be independently cell block, and circumferentially arrange one group uniformly at intervals along pier body 10 top, each cell block is connected with pier body 10 sidewall by corresponding elastic component 22.When being applied to over-height pier, cell block arranges many groups along the longitudinal separation of pier body 10.
Some principles of the above the utility model passive type dynamic absorber bridge pier that just explains 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.
