Prefabricated seismic isolation fireproof and active self-cleaning bearing system and implementation method thereof

A prefabricated fireproof and active self-cleaning seismic isolation bearing system, comprising:

• an upper structure (1), a lower structure (2), and a rubber body (3) positioned therebetween;
• and further comprising:
• a functional body and a circulation equipment, wherein the functional body comprises a water receiving tank (5) formed by fixing a rectangular frame (5-2) on a bearing lower plate (5-1), wherein the bearing lower plate (5-1) is mounted on the lower structure (2), wherein a water outlet elbow (11) is provided on the lower structure (2), and the water outlet elbow (11) is connected to the water receiving tank (5);
• wherein a bearing upper plate (4) is mounted under the upper structure (1), a water inlet elbow (10) is provided on the upper structure (1), and the water inlet elbow (10) is connected to the bearing upper plate (4);
• a rubber body (3) is provided between the bearing lower plate (5-1) and the bearing upper plate (4), a plurality of water spray coils (6) are fixed at intervals outside the rubber body (3), the plurality of water spray coils (6) each having a short pipe (6-2), and a conical nozzle (9) is connected on each short pipe (6-2);
• a water inlet hose (7) is connected to the plurality of water spray coils (6) through a plurality of water distribution ports (7-2);
• the water inlet elbow (10) is connected to the plurality of water spray coils (6) through the water inlet hose (7);
• the circulation equipment comprises a drainage pump, a water tower, a water reservoir, a filter screen, a water supply pump and a second end (B2) of a switching valve which are connected in sequence;
• wherein an air supply pump is connected with a first end (B1) of the switching valve, an opposite end (A) of the switching valve is connected to an outer end of the water inlet elbow (10) of the functional body, and an water inlet end of the drainage pump is connected to an outer end of the water outlet elbow (11) on the functional body,
• wherein the rubber body (3) comprises an odd number of rubber circular pads (3-1) clamping an even number of circular steel plates (3-2) and the rubber circular pads (3-1) are aligned with circular steel plates (3-2);
• according to a water spray coverage range in a height direction of the conical nozzle (9), a number of the circular steel plates (3-2) are selected at intervals and four-hole layered rubber ring pads (3-3) are tightly covered on peripheries of the selected number of the circular steel plates (3-2);
• peripheries of the circular steel plates (3-2) which are not selected are all tightly covered with rubber ring pads (3-4);
• all four holes of each layer of the four-hole rubber ring pads (3-3) are vertically aligned, perpendicular to an edge line of the bearing lower plate (5-1) and all inserted into a respective four steel plate reinforcements (3-5);
• one end of the respective four steel plate reinforcements (3-5) is connected to an outer surface of the circular steel plate (3-2), and an opposite end of the respective four steel plate reinforcements (3-5) extends out of the four-hole rubber ring pad (3-3) with an equal length.
