At the same time, the upper damping C-shaped ring plate 4 will also compress and deform under stress, consuming some of the seismic energy.

[0078] When subjected to Z-axis pressure, the rubber buffer device 5 in the middle compresses and deforms, thereby achieving Z-axis vibration isolation of the structure.

At the same time, the lower damping C-shaped ring plate 10 will also compress and deform under stress, consuming some of the seismic energy.

[0080] This energy-dissipating device consumes seismic energy in the X, Z, and Y directions, thereby achieving the purpose of vibration reduction.
