S5, after basic upper beam concrete reaches some strength, on the top of basic upper beam spacing hole (12), steel plate (15) is installed, the circular hole (16) of steel plate (15) contacts with basic upper beam upper surface through reinforcing bar (9), rigid gasket (17) is positioned over steel plate (15) top through reinforcing bar (9), by rubber sheet gasket (18) through reinforcing bar (9), and be placed in the top of rigid gasket, finally nut (18) is screwed in reinforcing bar (9) end of thread, nut contacts with rubber sheet gasket, and rubber sheet gasket can not be made to be out of shape;
S6, treat that basis upper underbeam construction is complete, after the installation such as Seismic Isolation of Isolation Layer, limit steel bar, carry out the construction of pointing with cement mortar (8) at isolation floor place;
S7, basic upper beam top masonry panel or build shear wall etc., form the isolation structure with self-adding formula bead-graphite sliding base isolated system.
