PURPOSE: A movable floor structure for seismic isolation is provided to make the movable floor not vibrate or vibrate at a very small amplitude even if a building structure largely vibrates by an earthquake, thereby safely protect equipment on the movable floor. CONSTITUTION: Plural lower frames(1) are continuously fixed on the bottom of a building in a row. Plural upper frames(2) are placed on the upper side of the lower frames(1), and are respectively opposite to the lower frames(1). A ball seismic isolation bearing(3) is equipped between the lower frame(1) and the upper frame(2). A deck frame(4) is fixed on the upper sides of the upper frames(2). The deck frame(4) is continuously fixed through two upper frames(2). A deck plate(5) is continuously fixed on the upper side of the deck frame(4). [Reference numerals] (AA) Building floor |
