[0002] In the field of construction, safety and stability are eternal pursuits. Among them, seismic isolation bearings have made innovative progress, giving buildings strong earthquake resistance. Through their unique design and working principle, seismic isolation bearings can effectively absorb and disperse seismic energy. When seismic waves strike, seismic isolation bearings are like flexible buffers, converting strong impact force into gentle energy release, thereby greatly reducing the pressure on the main structure of the building.

[0003] The existing seismic isolation bearing is composed of multiple layers of rubber and multiple layers of steel plates alternately stacked together. The rubber and steel plates inside the existing seismic isolation bearing are alternately stacked together, and the top connecting steel plate and the shock-absorbing part in the middle part do not have corresponding shock-absorbing structures, which easily leads to increased wear of the rubber and steel plate in the middle part, which is not conducive to releasing the vibration energy of the top connecting steel plate. For this reason, we propose a seismic isolation bearing with a decompression structure. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4 The utility model provides a technical solution: a seismic isolation bearing with a decompression structure. The solution is used to solve the problem that the existing seismic isolation bearing does not have the top shock absorption effect, which leads to aggravated internal damage. The design of the solution includes an upper embedded plate 1, an upper connecting steel plate 2, an intermediate steel ring layer 3, a lower connecting steel plate 4 and a lower embedded plate 5, and each plate is connected in sequence. A plurality of lead layers 6 are arranged inside the intermediate steel ring layer 3, and a plurality of partition layers 7 are arranged in each lead layer 6. The partition layer 7 is filled with a viscoelastic body. The viscoelastic body is a polymer material and is an existing structure with viscosity and elasticity, so it has a good shock absorption effect. A shock absorbing air pipe 8 is connected between the intermediate steel ring layer 3 and the upper connecting steel plate 2. A top shock absorbing release piece is connected to the upper connecting steel plate 2. A plurality of shock absorbing through holes 16 are arranged on the upper embedded plate 1 and the lower embedded plate 5. The air generated by the top shock absorbing release piece is released to the partition layer 7 through the shock absorbing air pipe 8.

[0020] The top shock-absorbing release member includes a steel plate layer 9 arranged at the bottom of the upper connecting steel plate 2. The interior of the steel plate layer 9 is a cavity structure. The cavity structure inside the steel plate layer 9 is filled with a group of symmetrically distributed rubber shock-absorbing layers 10, and an extruded gas piece is connected between the two rubber shock-absorbing layers 10, and the extruded gas piece is connected to the shock-absorbing air pipe 8.

[0021] The rubber shock-absorbing layer 10 is distributed in a curved and folded manner, and each rubber folded layer is filled with rubber material, and the upper portion of the rubber material is in a flat plate shape, and the lower portion is in an arched transition shape.

[0022] The extruded gas part includes a rubber airbag body 11 connected to the outside of the rubber shock-absorbing layer 10, and a transverse pipe 12 is connected between the two rubber airbag bodies 11. A shock-absorbing section is provided at the connection between the transverse pipe 12 and the rubber airbag body 11, and the middle part of the transverse pipe 12 is connected to the shock-absorbing air pipe 8.

[0023] A guide block 13 is provided at the connection between the lead layer 6 and the shock-absorbing air pipe 8, and a plurality of guide air ports 14 are distributed on the guide block 13. A plurality of groups of air holes 15 corresponding to the guide air ports 14 are distributed at the connection between the shock-absorbing air pipe 8 and the guide block 13. Fractures are distributed on the partition layer 7 for the flow of viscoelastic body.

[0024] During installation and use, the upper embedded part 1 is first installed on the upper part of the building, and then the upper connecting steel plate 2 is installed. Since the rubber shock-absorbing layer 10 is installed and fixed inside the steel plate layer 9 of the upper connecting steel plate 2, and then the shock-absorbing air pipe 8 is passed through the cover plate of the steel plate layer 9, the middle steel ring layer 3 is assembled at this time, and the middle steel ring layer 3 is welded to the bottom of the steel plate 9. The multi-layer lead layer 6 inside is wrapped around the outside of the shock-absorbing air pipe 8. Finally, the lower connecting steel plate 4 and the lower embedded plate 5 at the bottom are assembled. When shock wave energy appears on the top of the building, the shock wave energy causes the compression transformation of the gas at the installation position. The gas enters the internal space of the steel plate layer 9 along the shock-absorbing through hole 16. At the same time, the rubber shock-absorbing layer 10 in the internal space is subjected to lateral shear force, thereby shrinking and changing, causing air changes, and then the generated gas changes are transmitted through the shock-absorbing air pipe 8. The generated gas is conducted to the partition layer 7, which is convenient for the viscoelastic body at the partition layer to transform, thereby achieving the effect of lateral shock absorption on the lead layer 6 and avoiding damage to the lead layer.
