A central connecting plate is provided between the two supporting conical rubber blocks. Splicing corner posts are evenly interspersed in the middle of the central connecting plate. A limiting outer ring is fixedly connected to the edge of the central connecting plate. An elastic hoop is embedded between the middle of the outer side of the limiting outer ring.

The pressure sensor is limited by the cooperation between the connecting top column and the supporting bottom column. The pressure sensor monitors the pressure between the mounting top plate and the mounting bottom plate to ensure that the seismic isolation bearing can maintain a proper shape during use.

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] Example: Figure 1-4 As shown, this utility model provides a technical solution, a novel seismic isolation bearing for building friction pendulum, including a mounting top plate 1, and a mounting base plate 2 is provided at the bottom of the mounting top plate 1;

[0034] An internal staggered buffer and shock absorption mechanism 3 is provided between the mounting top plate 1 and the mounting bottom plate 2;

[0035] The internal staggered buffer and shock absorption mechanism 3 includes a supporting conical rubber block 301, a central connecting plate 302, a splicing corner post 303, a limiting outer ring 304, an elastic hoop ring 305, an installation outer ring 306, and a supporting spring 307.

[0036] Both the bottom surface of mounting plate 1 and the top surface of mounting plate 2 are bolted together with supporting conical rubber blocks 301. A central connecting plate 302 is provided between the two supporting conical rubber blocks 301. Splicing corner posts 303 are evenly interspersed in the center of the central connecting plate 302. A limiting outer ring 304 is fixedly connected to the edge of the central connecting plate 302. An elastic hoop 305 is embedded between the middle of the outer side of the limiting outer ring 304. An installation outer ring 306 is provided inside the elastic hoop 305. Supporting springs 307 are symmetrically fixedly connected to the outer side of the installation outer ring 306 at positions corresponding to the inner positions of the elastic hoop 305. The ends of the splicing corner posts 303 are interlocked with the supporting conical rubber blocks 301. The outer conical surface of the limiting outer ring 304 is tightly fitted with the outer side of the supporting conical rubber blocks 301. The ends of the supporting springs 307 are also connected to the installation outer ring 306. The inner walls of the outer ring 306 are fixedly connected. The two supporting conical rubber blocks 301 are spliced ​​together through the cooperation between the central connecting plate 302 and the splicing corner column 303. The splicing corner column 303 limits the supporting conical rubber blocks 301, and the limiting outer ring 304 limits the side of the supporting conical rubber blocks 301. Thus, when the seismic isolation bearing is subjected to severe external vibration, the vibration can be buffered by the horizontal displacement and elastic deflection of the two supporting conical rubber blocks 301. The supporting spring 307 is installed inside the elastic hoop 305 by installing the outer ring 306. The vibration energy is stored by the deformation of the elastic hoop 305 and the supporting spring 307 to prevent the vibration from passing through the seismic isolation bearing and transmitting upward to the bottom of the building, causing damage to the building. This effectively improves the stability and safety of the seismic isolation bearing.

[0037] The bottom of the mounting base plate 2 is provided with a snap-fit ​​limiting connection mechanism 4;

[0038] The snap-fit ​​limiting connection mechanism 4 includes a snap-fit ​​circular groove 401, a filling rubber block 402, a mounting clip 403, an auxiliary connecting pin 404, and a fixing nut 405;

[0039] The bottom edge of the mounting base plate 2 has evenly spaced snap-fit ​​grooves 401 along its circumference. Filler blocks 402 are spaced at intervals inside the corresponding snap-fit ​​grooves 401. Mounting blocks 403 are inserted into the snap-fit ​​grooves 401. An auxiliary connecting nail 404 is fixedly connected to the center of the bottom surface of each mounting block 403. A fixing nut 405 is threaded onto the center of the top of each mounting block 403. The filler blocks 402 and mounting blocks 403 are alternately distributed. The bottom surface of the mounting block 403 is flush with the bottom surface of the mounting base plate 2. The filling block 402 and the mounting block 403 can be installed to the bottom of the mounting base plate 2 through the snap-fit ​​groove 401. The filling block 402 can seal the unused snap-fit ​​groove 401. The top of the mounting block 403 is fixed and limited by the fixing nut 405. The bottom of the mounting base plate 2 is limited by the auxiliary connecting nail 404 inserted into the mounting surface, which further improves the stability of the seismic isolation bearing installation.

[0041] The auxiliary testing mechanism 5 includes a hexagonal bracket 501, a connecting top column 502, a pressure sensor 503, and a supporting bottom column 504;

[0042] A hexagonal bracket 501 is snapped onto one side of the bottom surface of the mounting top plate 1. A connecting top column 502 is fixedly installed in the middle of the bottom surface of the hexagonal bracket 501. A pressure sensor 503 is fixedly connected to the bottom end of the connecting top column 502. A supporting bottom column 504 is fixedly connected to the bottom end of the pressure sensor 503. The signal output end of the pressure sensor 503 is connected to the signal input end of an external signal collection terminal. The bottom surface of the supporting bottom column 504 is tightly fitted to the top surface of the mounting base plate 2. The connecting top column 502 and its bottom components are installed to the bottom of the mounting top plate 1 through the hexagonal bracket 501. The pressure sensor 503 is limited by the mutual cooperation between the connecting top column 502 and the supporting bottom column 504. The pressure sensor 503 monitors the pressure between the mounting top plate 1 and the mounting base plate 2 to ensure that the seismic isolation bearing can maintain a suitable shape during use.

[0043] The working principle and usage process of this utility model: When the seismic isolation bearing is needed, the seismic isolation bearing needs to be installed in a suitable position by installing the top plate 1 and the bottom plate 2. The two supporting conical rubber blocks 301 are spliced ​​together by the cooperation between the central connecting plate 302 and the splicing corner column 303. Then, the supporting conical rubber blocks 301 are limited by the splicing corner column 303.

[0044] Then, the outer limiting ring 304 limits the side of the supporting conical rubber block 301, so that when the seismic isolation bearing is subjected to severe external vibration, the vibration can be buffered by the horizontal displacement and elastic deflection of the two supporting conical rubber blocks 301. Then, the supporting spring 307 is installed inside the elastic hoop 305 by the installation outer ring 306, and the vibration energy is stored by the deformation of the elastic hoop 305 and the supporting spring 307, so as to prevent the vibration from passing through the seismic isolation bearing and transmitting upward to the bottom of the building and causing damage to the building, thereby effectively improving the stability and safety of the seismic isolation bearing.

[0045] When it is necessary to provide auxiliary limiting for the bottom of the mounting base plate 2, the filling block 402 and the mounting block 403 can be installed on the bottom of the mounting base plate 2 through the snap-fit ​​groove 401. The filling block 402 can seal the unused snap-fit ​​groove 401, and the top of the mounting block 403 can be fixed and limited by the fixing nut 405. The bottom of the mounting base plate 2 can be limited by the auxiliary connecting nail 404 inserted into the mounting surface, which further improves the stability of the seismic isolation bearing installation.

[0046] When it is necessary to test the service status of the seismic isolation bearing, the connecting top column 502 and its bottom components are installed to the bottom of the mounting top plate 1 through the hexagonal bracket 501. The pressure sensor 503 is limited by the cooperation between the connecting top column 502 and the supporting bottom column 504. The pressure sensor 503 monitors the pressure between the mounting top plate 1 and the mounting bottom plate 2 to ensure that the seismic isolation bearing can maintain a proper shape during use.
