Description of the Related Art As one of magnetic levitation type seismic isolation structures for buildings, a plurality of magnetic levitation devices using magnets and superconductors levitate the building from the ground, which causes vibrations between the building and the ground. There are things that suppress the propagation between and. In this seismic isolation structure, the magnet of each magnetic levitation device is arranged on one of the ground and the building, and the superconductor is arranged on the other of the ground and the building. However, this known seismic isolation structure
Due to the Meissner effect caused by the superconductor being a perfect diamagnetic material, the building is levitated from the ground, so the levitation force is weak, and the building is easily displaced with respect to the ground, which is unstable. Therefore, when a horizontal force acts on the building, the building may fall or stand still in a displaced state.

により、前記と同様の問題点を有する。As another magnetic levitation type seismic isolation structure for a building, a plurality of magnetic levitation devices using a pair of superconducting electromagnets are used to levitate the building from the ground, whereby the space between the building and the ground is increased. There is something that suppresses the propagation of vibration. In this seismic isolation structure, the superconducting electromagnet of each magnetic levitation device is arranged in the ground and the building. However, this seismic isolation structure causes the building to levitate from the ground due to the repulsive force of the superconducting electromagnet, so that the building is easily displaced with respect to the ground and is unstable, so that the horizontal force acts on the building. By doing so, there is a problem similar to the above.

電導体とを含む。A seismic isolation structure of the present invention includes a plurality of magnetic field generating means for generating a magnetic field for floating a building above the ground. The magnetic field generating means is a magnetic field generator disposed on one of the ground and the building to generate a magnetic field for levitating the building from the ground, and at least one superconductor having an inhomogeneous portion therein.

る。The building is kept floating above the ground due to the magnetic repulsion between the magnetic field generator and the superconductor. Thus, the vibration of the ground caused by an earthquake or the like is attenuated and transmitted to the building, and the vibration generated in the building is attenuated and transmitted to the ground. The magnetic field generated by the magnetic field generator does not occur when a superconductor having no inhomogeneous portion inside is used in cooperation with the superconductor having the inhomogeneous portion inside, so-called pinning effect (pinning effect). Phenomenon) occurs. Due to this pinning effect, a large repulsive force acts between the magnetic field generator and the superconductor as compared with the conventional seismic isolation structure that utilizes the superconducting phenomenon, and the relative displacement between the magnetic field generator and the superconductor. If this occurs, this displacement will be corrected. Therefore, the building is corrected to the correct position with respect to the ground regardless of whether the building is displaced in the horizontal direction or the vertical direction with respect to the ground by the force that moves the building with respect to the ground.

Compared with the seismic isolation structure using the phenomenon, the levitation force is large and the building can be maintained stably.
