Technical Field

[0002] Earthquakes pose a major challenge to human society. They not only threaten people's lives and property but also may cause damage to residences and infrastructure and interrupt public transportation. Therefore, it is particularly important to adopt effective earthquake prevention measures to reduce the damage caused by earthquakes. In traditional buildings, strategies for resisting earthquakes usually include enhancing the bearing capacity or plastic deformation capacity of components, absorbing earthquake energy in this way to reduce the deformation and damage caused by earthquakes. However, this method is often costly and may affect the aesthetics. In contrast, the seismic isolation technology blocks the transmission of earthquake energy by embedding seismic isolation elements in the building structure, thus safeguarding the safety of the building itself. This technology can effectively reduce the impact of earthquakes on buildings, improve the overall seismic performance by extending the fundamental period of the structure, and bring significant economic benefits. In the case of existing friction bearings under earthquakes or other strong loads, the horizontal displacement between the upper and lower plates cannot be effectively buffered, and it is difficult to reset after an earthquake, nor can the state of the bearing be known.

[0008] An intelligent monitoring sliding plate bearing with a self - reset function provided by the present utility model isolates the vibration wave energy during earthquakes or other vibrations. At the same time, some sliding displacements occur on the contact surfaces of the upper polytetrafluoroethylene sliding plate and the lower polytetrafluoroethylene plate.
