SEISMIC ISOLATION JACK DEVICE AND SEISMIC ISOLATION DEVICE REPLACEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a seismic isolation device replacement method, which enables work to be conducted without imposing horizontal force on a seismic isolation support part, and seismic isolation device replacement work to be conducted so that a seismic isolation performance of a building is maintained.SOLUTION: A seismic isolation device replacement method comprises following processes: to dispose a seismic isolation support jack device 3 around an existing seismic isolation device 2 and fix a lower linear slider 5 on a foundation slab 11; to extend a support jack 6 to make an upper linear slider 4 butt to a lower flange 10A of a beam material 10 and bear a load of an upper structure; to fix the upper linear slider 4 to the lower flange 10A of the beam material 10 using a friction joint jig; to remove the existing seismic isolation device 2 from between the beam material 10 and the foundation slab 11; to fix another seismic isolation device 2 to a fitting part between the beam material 10 and the foundation slab 11; and to remove the seismic isolation support jack device 3 from between the beam material 10 and the foundation slab 11.SELECTED DRAWING: Figure 1
