Title:
SLIDE BEARING
Document Type and Number:
Japanese Patent JP2022183528
Kind Code:
A
Abstract:
To provide a slide bearing which is advantageous for damping large seismic energy while reducing an occupied space and costs.SOLUTION: When a large horizontal force is exerted on a building by an earthquake, a control unit 28 causes a magnetic force generation part 26 to generate a magnetic force according to a magnitude of the vibration quantity detected by a sensor 38. The magnetic force acts as a force which attracts a downward-facing slide surface 20 to an upward-facing slide surface 18, and thus the downward-facing slide surface 20 receives a resistance from an outer periphery part 1804. Further, the magnetic force is applied to a magnetic viscous fluid 24 to increase the viscosity of the magnetic viscous fluid 24 and cause a leg part 30 to receive a resistance caused by the magnetic viscous fluid 24. When a large horizontal force is exerted on a building, two kinds of resistances occur to inhibit swinging of the building with larger damping force.SELECTED DRAWING: Figure 1
