Three-dimensional isolator for vibration-seismic dual control

A three-dimensional isolator for vibration-seismic dual control, comprising:

• an isolator body, the isolator body comprising a plurality of middle-layer connecting plates and a plurality of rubber module units, the middle-layer connecting plates being vertically arranged at intervals, and the rubber module units being arranged on the upper surfaces and the lower surfaces of the middle-layer connecting plates in parallel and connecting the middle-layer connecting plates into a whole;
• isolator components, the isolator components comprising cover plate components and pre-tightening pieces, the cover plate components comprising an upper cover plate, a lower cover plate and side walls which define an isolator cavity, a flange plate being arranged on the top of the side wall, a gap being reserved between the upper cover plate and the flange plate, the isolator body being fixedly arranged in the isolator cavity, and the pre-tightening piece being arranged between the flange plate and the upper cover plate in a penetrating mode so that the isolator body can be in a pre-pressing state;
• an upper pre-buried plate arranged above the upper cover plate and a lower pre-buried plate arranged below the lower cover plate, wherein the upper pre-buried plate and the lower pre-buried plate are fixedly connected with the upper cover plate and the lower cover plate through bolts respectively;
• and
• lining plate components, wherein the lining plate components comprise a plurality of lining plates with different thicknesses, and the lining plates are inserted between the lower cover plate and the lower pre-buried plate in the state that the pre-tightening pieces are disassembled.
