Description
Technical field
The utility model is related to technical field of bridge more particularly to a kind of flexibility to subtract shock insulation pot rubber bearing.
Background technology
With the rapid growth of China's economy, the development that highway bridge construction cause is advanced by leaps and bounds is various across river
(river), bridge spanning the sea come into being, and bridge type contains many structures such as arch bridge, concrete girder bridge, suspension bridge and oblique pull latch bridge
Form.Bridge pad as one of bridge structure important component has also obtained quick development and extensive use.
Firstly the need of it is clear that：Bridge is the bridge in movement.As the building blocks of function of bridge, bearing must adapt to bridge
The various movements that beam generates in the process in operation, suitable bridge is other than displacement caused by linear temperature variation for the movement of bridge, also
Because many factors such as nonlinear temperature variation, concrete shrinkage and creep, car load, wind load, earthquake cause direction across bridge displacement,
Level angle displacement, vertical corner displacement and lateral corner displacement, the moment oscillating motion especially generated in earthquake, to branch
The antidetonation of seat, energy dissipating, displacement limitation have higher requirement.
Traditional pot rubber bearing is simple in structure, has only played vertical pressure-bearing in bridge use, horizontal bearing and
Horizontal displacement, and horizontal displacement is limited without resulting structure, belong to no limiting displacement, beam body moment position easily occurs in earthquake
It moves past greatly, makes support displacement structure by severe impact, eventually lead to cutting, generation falls off or Bearing Seat Force comes to nothing, and causes
Other Bearing Seat Forces it is excessive thus damage, serious destruction easily is caused to bridge.
Thus applicant carried out beneficial exploration and trial, result of the above problems is had found, will be detailed below being situated between
The scheme to continue is generated under this background.
