<P>PROBLEM TO BE SOLVED: To provide a seismic isolation bearing which uses a shock absorbing pad to enhance ability to isolate seismic energy. <P>SOLUTION: The seismic isolation bearing includes a lower and an upper plate separated by a slider. The lower plate has an upward facing concave surface while the upper plate has a downward facing concave surface, and the slider includes a first member and a second member separated by the shock absorbing pad. The first member has an upper convex surface to slide along the concave surface of the upper plate while the second member has a lower convex surface sliding along the concave surface of the lower plate. When an earthquake is generated, the lower and upper plates move relatively through the slider between them, and the seismic energy in the horizontal direction may be dispersed. Furthermore, the shock absorbing pad is deformed to absorb the seismic energy in the vertical direction. Accordingly, the seismic isolation bearing can enhance the ability to isolate the seismic energy. <P>COPYRIGHT: (C)2013,JPO&INPIT |
