The glass-reinforced epoxy resin is filled with a plurality of elastic rubbers 3, and a protective outer rubber 5 is provided on the peripheral wall of the glass-reinforced epoxy resin, and the protective outer rubber 5 also wraps the peripheral walls of the upper sealing plate 1 and the lower sealing plate 2.
[0033] Reference Figure 1 , by using glass-reinforced epoxy resin instead of traditional carbon steel partitions to reduce the deadweight of the seismic isolation bearing and reduce the volume of the seismic isolation bearing. By adding glass-reinforced epoxy resin, the deformation and rebound performance of the seismic isolation bearing in the horizontal direction is enhanced, so that the seismic isolation bearing can better absorb vibrations and improve the shock absorption performance of the seismic isolation bearing. At the same time, wrapping a number of elastomer rubbers 3 with glass-reinforced epoxy resin will reduce the aging rate of a number of elastomer rubbers 3, thereby increasing the overall service life of the seismic isolation bearing.
[0034] Reference Figure 1 , three embedded anchor bars 6 are arranged on both the sealing plate and the lower sealing plate 2. The three embedded anchor bars 6 on the upper sealing plate 1 are arranged equidistantly, and the three embedded anchor bars 6 on the lower sealing plate 2 are arranged equidistantly. The two embedded anchor bars 6 on the upper sealing plate 1 that are farthest apart are bent away from the end of the upper sealing plate 1 to form a first bending portion 61, and the bending directions of the two first bending portions 61 are opposite. The two embedded anchor bars 6 on the lower sealing plate 2 that are farthest apart are bent away from the end of the lower sealing plate 2 to form a second bending portion 62, and the bending directions of the two second bending portions 62 are opposite. When the seismic isolation bearing is installed, multiple embedded anchor bars 6 are directly inserted into the connected wall, thereby enhancing the connection stability between the seismic isolation bearing and the wall.
[0035] Reference Figure 2 The present embodiment also discloses a masonry structure with a seismic isolation bearing, which includes, from bottom to top, a concrete cushion layer 71, a foundation layer 72, a lower ring beam 73, a seismic isolation bearing, an upper ring beam 74, and a brick wall 75, and one side of the foundation layer 72 is an outdoor floor 77. Multiple embedded anchor bars 6 on the upper sealing plate 1 extend into the upper ring beam 74, and multiple embedded anchor bars 6 on the lower sealing plate 2 extend into the lower ring beam 73. The lower ring beam 73 and the upper ring beam 74 are both integrally cast with concrete. When the upper ring beam 74 is formed, it will wrap around the multiple embedded anchor bars 6 on the upper sealing plate 1, and when the lower ring beam 73 is formed, it will wrap around the multiple embedded anchor bars 6 on the lower sealing plate 2, thereby ensuring the connection stability between the seismic isolation bearing and the upper ring beam 74 and the lower ring beam 73.
