Problems solved by technology

Due to the large overturning moment of high-rise buildings under the action of earthquakes, the axial force of the column will change greatly, which will cause the energy dissipation capacity of the traditional friction pendulum to be unstable.

Abstract

The invention provides a frictional pendulum sliding support. Through a first slide block and a second slide block which are arranged at intervals and arranged between a first installing plate and a second installing plate, and a through hole arranged in the center of the first slide block and the second slide block, an elastic element is arranged in the through hole. Friction plates at both ends of the elastic element, and the first installing plate and the second installing plate are respectively rubbed with a first friction curve face of the first installing plate and a second friction curve face of the second installing plate under the pressure function provided by the elastic element so as to eliminate the shock energy. For the elastic element can continuously provide stable pressure for the first friction curve face and the second friction curve face, the frictional pendulum sliding support has higher stability, and can be used for a long time.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a sliding bearing of a friction pendulum. Background technique [0002] In order to make the building structure have a strong ability to resist external damage such as earthquakes, it is often necessary to add energy-dissipating components to the structure. Aseismic isolation technology has been more and more widely used in building structures, and the energy absorber, as the core component of the seismic isolation scheme, directly determines the efficiency and pros and cons of the scheme. [0003] Common shock-absorbing energy-dissipating components include viscous dampers, friction dampers, magnetorheological dampers, and energy-dissipating supports. The common vibration-isolation and energy-dissipating components include friction pendulums, vibration-isolation pads, etc. The friction damper is a device that converts the vibration energy of the building into ...
