The extension period of support is shaken to reduce superstructure horizontal inertial force, and the displacement for reducing earthquake by the energy consumption of shock mount is rung
It answers；And shock mount substructure does not often need to carry out special design, cost is relatively low；In addition, shock mount is mentioning
While for certain cushioning ability, moreover it is possible to meet structure requirement used in everyday.
At present in the engineerings such as Large Scale and Continuous beam bridge, long-span cablestayed bridges, the movable bearing support displacement of abutment pier, auxiliary pier etc.
Very big, according to shock mount, damping effect is very good.But the movable bearing support of abutment pier, auxiliary pier etc. often normally makes
Pulling force can be generated in, needed using mode tensile supporting seat.Under geological process, this pulling force is also possible to bigger.Due to abutment pier, auxiliary pier etc.
The movable bearing support at place under geological process should tension, damping again, solution get up to have certain difficulty.Although currently, having one
A little solutions, but the shock mount size designed is very huge, construction is complicated, cost is very high.
Summary of the invention
The purpose of this utility model is overcome the deficiencies in the prior art, proposes that a kind of super large is displaced dual damping and tensile branch
Seat, can both provide vertical bearing capacity, horizontal bearing capacity, turning power, the displacement capacity under normal use, also have dual subtract
Shake function, to effectively reduce the seismic response of bridge structure under geological process, not only can satisfy Large Scale and Continuous beam bridge, greatly across
The movable bearing support of the engineerings such as cable-stayed bridge abutment pier, auxiliary pier etc. should tension, the functional requirement of damping again, but also have body
The advantages that long-pending smaller, simple and compact for structure, good damping effect, each component are conveniently replaceable, repair.
In order to achieve the above objectives, the utility model provides following technical solution:
A kind of dual damping and tensile support of super large displacement, including support, steel damper, viscous damper and vertical tension group
