The method and apparatus for manufacturing of seismic isolation plug of seismic isolation system for

摘要

PPROBLEM TO BE SOLVED: To provide a production method of a base isolation plug, capable of performing accurate molding to a predetermined shape and improving the damping performance and displacement follow-up property of a base isolation device without using lead as the material, and production equipment of base isolation plug capable of performing the method. PSOLUTION: In the production method of a base isolation plug 9 for base isolation device, when a powdery material 2 filled in a mold 3 is clamped to pressure mold two pressure receiving surfaces, the two pressure receiving surfaces of the powdery material 2 are pressure-molded into a shape such that the center is protruded, compared with the periphery, and both the surfaces are then pressure-molded into a planar shape. The base isolation plug 9 is produced by using the production method. The production equipment capable of performing the production method includes the mold 3 and a stamper 5.
