Description
Technical field
The utility model belongs to bearing technical field more particularly to a kind of resistance to plucking physical pendulum friction pendulum support.
Background technology
In Bridge Design, for bearing as critical piece, the load that carry bridge top passes to substructure, and
And meet the needs of rotation and the displacement of superstructure.When coming earthquake, friction pendulum support passes through upper and lower concave spherical surface and spherical surface
The friction energy-dissipating of wear-resistant material reduces damage of the seismic force to bridge.Simultaneously as frictional resistance is smaller so that bearing is by pier
It is detached with beam body, reduces the power that seismic force passes to beam body by bridge pier, extend the period of motion of beam body, reduce to beam body
Injury.Earthquake will produce Vertical Seismic Load and horizontal seismic force when occurring, and existing friction pendulum support is essentially all according to water
Level land brisance energy consumption, which is reduced, designs beam body injury, because it will appear the problem of beam body is lifted, existing ball in swing process
The vertical tension design of type bearing is not suitable for friction pendulum support, therefore the friction pendulum support used in bridge and building does not have
The ability of vertical antidetonation.Although there is part anti-pulling friction pendulum support, realized using the cooperation of the boss of limiting plate and intermediate plate anti-
Function, the structure is drawn to be only used for the bearing in original original state, friction pendulum support is mostly big displacement friction energy-dissipating, the branch
Seat loses tension function in earthquake after limiting plate is cut.The tension occurred during bearing normal use after corner is linear
Tension baffle is easy to destroy.Some structures are designed using cambered surface tension plate, when support displacement is larger, bearing tensile structure ruler
It is very little very big, it is not suitable for present bridge pier slimline design.
