Method of installing seismic isolation floor

摘要

A method of installing a base isolation floor includes a base arrangement process for installing a plurality of plate-shaped bases, which are formed so that a plurality of upward convex curved surface portions are aligned on an upper surface, on double-sided tapes applied onto an upper surface of a floor over a plurality of columns to be substantially parallel to each other and thereby arranging the bases on the upper surface of the floor and a slide plate installation process for installing a plurality of plate-shaped slide plates having a substantially flat lower surface on the base.

1. A method of installing a base isolation floor, the method comprising:
installing a plurality of plate-shaped bases on a nonslip sheet which is placed on a floor surface, wherein the nonslip sheet has a friction coefficient larger than that of the floor surface, and wherein the plurality of bases have a plurality of upward convex curved surface portions aligned on upper surfaces thereof; installing a plurality of plate-shaped slide plates, each having a substantially flat lower surface, on the bases such that the slide plates are movable by an earthquake motion; and pulling an end of the nonslip sheet to slide the nonslip sheet along the floor surface to position the slide plates and the bases beneath a bottom portion of a piece of equipment, and installing the piece of equipment onto the slide plates; wherein the bases and the slide plates are installed such that a slide plate among the slide plates is movable by the earthquake motion to be dropped from above the bases onto the floor surface around the bases, and moved on the floor surface by inertia to be decelerated and stopped.
