Description

Technical Field

[0001] The utility model relates to the technical field of rocking supports, in particular to a novel friction pendulum seismic isolation support. Background Art

[0002] The friction pendulum isolation bearing is a device that uses the pendulum principle and sliding interface friction to achieve seismic isolation. Friction pendulum bearings have been widely used in the seismic isolation design of bridges, buildings and equipment foundations. In bridge engineering, friction pendulum bearings can be installed between the bridge piers and the bridge deck to reduce the impact of earthquakes on the bridge deck; in construction engineering, friction pendulum bearings can be used in the seismic isolation design of multi-story and high-rise buildings to improve the seismic resistance of buildings.

[0003] The prior art, for example, a utility model of a seismic isolation friction pendulum bearing, authorization announcement number CN214993026U, has a plurality of wear-resistant slide plates so that the swing bearing has a very good seismic resistance and a long service life. A reset spring is provided so that the swing bearing can be reset after each seismic resistance, which also enhances the seismic isolation effect.

[0004] At present, there is still a lack of a bearing that can achieve rapid resetting of the friction pendulum seismic isolation bearing after earthquake resistance by setting springs in multiple directions, thereby enhancing the seismic isolation effect.

[0005] Therefore, in view of the above problems, a new type of friction pendulum isolation bearing is proposed to solve the above problems. Utility Model Content
