Bridge pier, and ensure that bridge span structure meets deformation requirements under load action.
With reference to the characteristics of this country and design requirement, friction pendulum support has nowadays been researched and developed, friction pendulum support
Cardinal principle is to be isolated bridge with ground using friction pendulum structure, and the superstructure of bridge is extended using friction pendulum structure
Natural vibration period, so as to effectively reduce because of seismic power augmentation effect.But, existing friction pendulum support is at least deposited
In following deficiency：
(1) when earthquake causes friction pendulum support to swing, the displacement of friction pendulum support is larger, causes the space occupied
It is larger；
(2) its stopping means used generally uses shear pin or similar structures, and horizontal shear force is generally large, it is necessary to cut
The quantity of power pin is more, causes structure to seem both bulk, and shear strength is unstable.
The content of the invention
It is an object of the invention to provide a kind of friction pendulum support, it aims to solve the problem that existing friction pendulum support is cut
The technical problem that power is unstable, space-consuming is big.
A kind of technical scheme that the present invention is provided：A kind of friction pendulum support, for be supported on bridge span structure and bridge pier it
