Description
Technical field
The utility model relates to bridge, particularly a kind of steel concrete variable cross-section rectangle hollow big frame pier that is applied to the inhomogeneous Gao Dun in high intensity Zone, large span continuous rigid structure.
Background technology
In the time that earthquake occurs, as bridge construction generation heavy damage, leading to the highway in disaster area cannot resume traffic, and will bring great difficulty to the timely rescue in disaster area, therefore, and very important of the overall anti-seismic performance that improves bridge construction.
At present, the large span continuous rigid structure bridge in high intensity Zone is carried out to anti-seismic performance analysis, can be controlled preferably by viscous damper and speed lock to displacement and internal force along bridge, there is no direct effective method for the displacement of direction across bridge and the control of internal force.Adopt traditional horizontal cantilever pier, in the time that pier height is higher, at the bottom of pier, Earthquake Internal Force can be very large, causes the pier basal cross section can be very large, and bridge pier can be very dangerous and very uneconomical; Meanwhile, pier top lateral displacement can be very large, even can cause the lateral impact of left and right width bridge, and bridge security is caused to very large impact.
Therefore, provide a kind of new structure to have extremely important meaning to improving high intensity Zone continuous rigid frame bridge anti-seismic performance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of steel concrete variable cross-section rectangle hollow big frame pier, with meeting under the prerequisite of normal usage function requirement, greatly improves integral bridge stability and anti-seismic performance.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Steel concrete variable cross-section rectangle hollow big frame pier of the present utility model, comprise that direction across bridge interval arranges the left side pier stud, the right side pier stud that adopt steel concrete variable cross-section rectangle hollow structure, left side pier stud, pier stud lower end, right side respectively with left side cushion cap, right side cushion cap is fixed is integrated, it is characterized in that: between the top of described left side pier stud, right side pier stud, be provided with the binder that consumes energy between pier stud, in left side pier stud, right side pier stud inner chamber corresponding arrange and pier stud between the binder that consumes energy form the diaphragm structure of Construction integration; Its two ends binder that consumes energy between the fixed cushion cap being integrated is with it set between described left side cushion cap, right side cushion cap.
The beneficial effects of the utility model are, structure innovation, and reasonable stress, power transmission is clear and definite, and anti-seismic performance is good, and whole structural stability is good, and rigidity is distributed and is adapted to pier High variation to pier stiffness requirement.And can by power consumption binder adjusting improve greatly bridge Earthquake Internal Force distribute; By with known without the comparative analysis of power consumption binder bridge construction, at the bottom of the displacement of pier top and pier stressed improvement very obvious, easy construction, economical rationality, improves integral bridge stability and anti-seismic performance greatly.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1 and Fig. 3, Fig. 4, steel concrete variable cross-section rectangle hollow big frame pier of the present utility model, comprise that direction across bridge interval arranges the left side pier stud 11a, the right side pier stud 11b that adopt steel concrete variable cross-section rectangle hollow structure, left side pier stud 11a, pier stud 11b lower end, right side respectively with left side cushion cap 21a, fixed being integrated of right side cushion cap 21b.Between the top of described left side pier stud 11a, right side pier stud 11b, be provided with the binder 13 that consumes energy between pier stud, in left side pier stud 11a, right side pier stud 11b inner chamber corresponding arrange and pier stud between the binder 13 that consumes energy form the diaphragm structure 12 of Construction integration.Its two ends binder 22 that consumes energy between the fixed cushion cap being integrated is with it set between described left side pier stud 11a, right side pier stud 11b.Left and right width bridge totally two variable cross-section rectangular hollow (left side pier stud 11a, right side pier stud 11b) by and pier stud top between the fixed formation transverse frame of binder 22 structure that consumes energy between the cushion cap that consumes energy between binder 13 and two cushion caps (left side cushion cap 21a, right side cushion cap 21b) between pier stud.Under geological process, between pier stud, consume energy and consume energy binder 22 as ductility dissipative member participation geological process between binder 13 and cushion cap.Under service load and " little shake " effect, the each position of full-bridge, in elastic stage, is not damaged.Under " shake greatly " effect, between pier stud, consume energy and consume energy binder 22 meetings prior to yield of pier formation plastic hinge between binder 13 and cushion cap, absorb seismic energy, thereby reduce the Earthquake Internal Force that bridge pier bears, ensure the safety of the main force structure of bridge pier.The power consumption binder reparation that plastic strain occurs is simple, after earthquake, can recover it by easy repair process and use function.
With reference to Fig. 2, the binder 13 that consumes energy between described pier stud, diaphragm structure 12 longitudinally arrange at interval on the top of left side pier stud 11a, right side pier stud 11b.For adaptation to the ground changes more complicated mountain area, can suitably regulate quantity, size and the spacing of between pier stud, consume energy binder 13, diaphragm structure 12, to change the lateral stiffness of steel concrete variable cross-section rectangle hollow big frame pier, thereby improve the anti-seismic performance of bridge construction entirety.
Steel concrete variable cross-section rectangle hollow big frame pier of the present invention has that anti-seismic performance is good, structure innovation, reasonable stress, power transmission is clear and definite, structural entity is stablized, the feature of easy construction.The little sand furrow bridge that it is successfully applied to Beihuan road, newly-built Lanzhou (two rings) eastern section engineering by applicant designs.With reference to Fig. 5, little sand furrow Bridge superstructure adopts (57+2 × 100+57) m Wavelike steel webplate continuous rigid frame, and this bridge basic earthquake intensity is 8 degree, and fortification against earthquakes grade is 9 degree.This bridge location is in the larger Liang Mao Gullied, loess plateau of hypsography, the high nearly 90m of main pier #4 pier, approximately 35 meters of main pier 4# and main pier #5 pier High Defferentials, genus high-intensity earthquake mountain area Long-span rigid frame bridge.Adopt tradition without the comparison of the hollow cantilever pier of power consumption binder steel concrete variable cross-section with main pier #2, main pier #3, main pier #4, main pier #5, adopting the steel concrete variable cross-section rectangle hollow main pier of big frame pier of the present invention top displacement maximum to reduce moment of flexure maximum more than 40%, at the bottom of pier reduces more than 20%, girder internal force is maximum to be reduced more than 20%, the anti-seismic performance of bridge is greatly improved, and the resistance to overturning of bridge has also obtained great increase simultaneously.
Some principles of the above the utility model steel concrete variable cross-section rectangle hollow big frame 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 the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
