MANUFACTURING METHOD OF SEISMIC ISOLATION PLUG FOR SEISMIC ISOLATION DEVICE, AND SEISMIC ISOLATION PLUG MANUFACTURED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a seismic isolation plug which can improve the attenuation performance and the displacement following performance of a seismic isolation device without using lead in a material.;SOLUTION: In the manufacturing method of the seismic isolation plug 7 which is formed by pressure-molding the powdery material 2, the powdery material 2 is pressure-molded by using a stamper 5A, a plurality of columnar plug materials 6 are manufactured, and the plurality of plug materials 6 are aligned in a metal mold 3B in parallel with one another. The manufacturing method of the seismic isolation plug 7 is also characterized in that the plurality of plug materials 6 are pressure-molded in a lump in axial directions X of the plug materials 6 by using the stamper 5B. Furthermore, the seismic isolation plug 7 is manufacturing by the method.;COPYRIGHT: (C)2011,JPO&INPIT
