VIBRATION-DAMPING FLOOR SLAB STRUCTURE FOR ENABLING CONTACT OF BALL BEARINGS WITH FLOOR SURFACE ALTHOUGH BALL BEARINGS ARE INSTALLED TO EACH BALL BEARING SUPPORT PART

摘要

PROBLEM TO BE SOLVED: To provide a base-isolated floor structure which is more inexpensive, lower and more lightweight than a conventional base-isolated floor using H-section steel, which can shorten a construction time, which can increase strength against a load, and which enables all ball bearings to come into contact with a floor surface, even if the ball bearings are installed in a ball bearing supporting part.;SOLUTION: In this base-isolated floor structure wherein a frame structure with the ball bearing supporting parts are moved on a floor surface via the ball bearings 30 so as to make base-isolating motions, the ball bearings 30 are installed in one ball bearing supporting part, and the ball bearing supporting part is equipped with an inclination following means 22 and a height adjusting means 20.;COPYRIGHT: (C)2005,JPO&NCIPI
