Description
Technical field
The present invention relates to bridges, in particular to a kind of to be applied to the high pier bridge earthquake resistance system in high intensity Zone and construction.
Background technique
The earthquake of the earthquake occurred in world wide in recent decades produces significant impact to Bridge Earthquake Resistance Design theory.
Many bridge structures are fallen due to being not provided with rationally effectively to subtract isolation measure and cause bridge structure that top beam body occurs after shake
The situation that beam or lower part pier stud destroy has seriously affected smooth traffic and has even threatened so that bed rearrangement bridge be made state of paralysis occur
To people's life and property safety, such case is especially apparent in the high pier bridge in high intensity Zone, therefore how to utilize bridge
Girder construction subtracts isolation structure or system and limits in a certain range the displacement of beam body and reduce geological process in substructure
The earthquake sheet of generation, enhancing antivibration capability of bridge are all the research emphasis of science of bridge building seismic resistance field always.
Bridge pier is higher, and its shock resistance is weaker, in high intensity Zone, when bridge pier height reaches a certain level, bridge pier
Shock resistance cannot be effectively improved by increasing section size or arrangement of reinforcement, and increasing section size is very uneconomical
's.It not only can satisfy highlight lines using the new Aseismic Structure System of the compositions such as high-strength tensile material, damper, flexible pier
The shockproof requirements of the high pier bridge in earthquake territory, can also significantly save project cost, this is to improve the high Dun Qiao in high intensity Zone
The new approaches of beam shock resistance.
In view of the above problems, the applicant has been devoted to develop a kind of high pier bridge earthquake resistance in high intensity Zone
System.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of high pier bridge earthquake resistance systems in high intensity Zone, with very big
Raising bridge entirety shock resistance and safety, and there is preferable construction convenience, wider applicability and preferable economy
Property.
The technical solution adopted by the present invention to solve the technical problems is as follows:
A kind of high pier bridge earthquake resistance system in high intensity Zone of the invention is related to beam body and provides the bridge of support for it
Pier, it is characterized in that: two way damper is being installed in the bottom of the beam body at bridge pier, or two-way in the installation of the top of bridge pier
The both ends of damper, two way damper are connect with strand spiral rope, and strand spiral rope extends downwardly after diverter, strand spiral rope
Lower end and earth anchor solid are at anchor connection.
The invention has the advantages that displacement of the beam body under geological process can effectively be limited, and the seismic energy that dissipates, subtract
The small larger internal force generated in bridge substructure due to geological process improves the whole anti-seismic performance and peace of bridge structure
Quan Xing；Mechanics principle is clear, and simple structure is easy for construction, and cost is relatively low；It can be by changing two way damper running parameter, turning
To the parameter adjustment systems working performance such as the angle of device and strand spiral rope specification, to meet different piers height, different across footpath bridge knots
The antidetonation demand of structure.
Detailed description of the invention
This specification includes following three width attached drawing:
Fig. 1 is a kind of side elevational view of the high pier bridge earthquake resistance system in high intensity Zone of the present invention；
Fig. 2 is the cross-sectional view of the line A-A along Fig. 1；
Fig. 3 is the enlarged drawing of the part B in Fig. 2.
Component and corresponding label: bridge pier 10, beam body 20, two way damper 30, strand spiral rope 31, diverter are shown in figure
32, anchor block 33.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Referring to FIG. 1, FIG. 2 and FIG. 3, a kind of high pier bridge earthquake resistance system in high intensity Zone of the present invention, is related to 20 He of beam body
The bridge pier 10 of support is provided for it.Two way damper 30 is being installed in the bottom of the beam body 20 at bridge pier 10, or in bridge
Two way damper 30 is installed at the top of pier 10, and the both ends of two way damper 30 are connect with strand spiral rope 31, and strand spiral rope 31 passes through
It is extended downwardly after diverter 32, the lower end of strand spiral rope 31 and ground anchoring 33 form anchor connection.
The two way damper 30, diverter 32, strand spiral rope 31 and the laterally setting of ground anchoring 33, act as lateral seismic
With.
The two way damper 30, diverter 32, strand spiral rope 31 and ground anchoring 33 are longitudinally disposed, act as to longitudinal earthquake
With.
Referring to Fig. 2, geological process is born by strand spiral rope 31 under small shake effect, only allows beam body 20 that lesser position occurs
It moves.The vibration prevention system permission beam body 20 being made up of under big shake effect two way damper 30, strand spiral rope 31 occurs limited
Displacement is effectively reduced bridge pier 10 under geological process and the internal force that generates, to reach the antidetonation purpose of bridge structure.Can have
Displacement of the effect limitation beam body 20 under geological process, and the seismic energy that dissipates, reduce since geological process is in bridge substructure
The larger internal force generated in bridge pier 10 improves the whole anti-seismic performance and safety of bridge structure.Mechanics principle is clear, construction letter
Single, easy for construction, cost is relatively low.And it can be by changing 30 running parameter of two way damper, the angle of diverter 32 and high-strength
The parameter adjustment systems working performance such as specification of cable wire 31, can easily meet different piers height, and different across footpath bridge structures resist
Shake demand.
Referring to Fig. 2, described ground anchor block 33 is connect with ground bolting, the lower end of strand spiral rope 31 and the fixed company of ground anchor block 33
It connects.
The above is this kind of some principle of the high pier bridge earthquake resistance system in high intensity Zone that explain through diagrams, and
It is non-be will invention be confined to shown in and the specific structure and the scope of application in, therefore it is all it is all may be utilized it is corresponding
Modification and equivalent, belong to invent applied the scope of the patents.
