The method for arranging of the superimposed shock isolating pedestal of sliding isolated bearing and rubber on the basis has: the circle along the building periphery is arranged the superimposed shock isolating pedestal of rubber, and inner ring is arranged sliding isolated bearing, and inner ring is arranged the superimposed shock isolating pedestal of rubber, arranged crosswise so again; Or superimposed shock isolating pedestal of rubber longitudinally, the alternate setting of sliding isolated bearing.
Beneficial effect:Compare with shock isolation method commonly used at present, the utility model has plurality of advantages:
1) this shock isolation method has reduced to import into about 1～2 times of the seismic forces in house, and successor's seismic forces is little, and the top material therefor is few, practices thrift investment;
2) this shock isolation method, when earthquake took place, the more traditional shock isolation method of the distortion of building can reduce 1～2 times, makes upper building be in elastic range, and not only building is safer, and indoor furniture decoration etc. does not have secondary disaster yet;
3) simple in structure, easy to make, cheap, it is convenient to construct.
4) buffer limiter not only has cushioning effect, but also has the effect of restriction building maximum distortion, and the maximum distortion that the maximum distortion of this permission and shock isolating pedestal allow is consistent.
5) after earthquake finished, if there is residual displacement in the house, the counter-force that then can rely on the counter-force pier to provide utilizes jack that the house is pushed up back original position, and was simple and easy to do.
6) promptly can be used for the seismic hardening of existing building, also can be used for the new building thing, applied widely.
