[0002] With the progress of science and technology, people's requirements for building safety are also higher and higher. In the field of building structure shock insulation and shock absorption control devices in China, there are many kinds of shock absorption products, but most of the products only have good effect on horizontal earthquake, and the effect of buffering vertical earthquake (including the vibration generated when trains, subways and trucks pass by) is not obvious, and these hazards are also greater.
[0003] In the traditional shock insulation support system, one type is a laminated rubber support shock insulation system, including rubber support and lead rubber support, etc. This type of support realizes shock insulation by prolonging the basic natural vibration period of the structure, but resonance caused by long-period components of the earthquake cannot be completely avoided, and the cost of the shock insulation layer of this type of support is relatively high. Among them, the most commonly used is laminated rubber support, and the specific types of laminated rubber support are natural rubber shock insulation support, high-damping rubber shock insulation support and lead rubber shock insulation support. From the above names, it can be found that the current shock insulation support mainly uses rubber material, and rubber has a large environmental pollution and poor quality reliability due to aging. The laminated rubber support is composed of steel plate and rubber, so it has the disadvantages of large equipment investment and high production cost. SUMMARY

The high-pressure gas in the support cavity can long-term bear the weight of the building. When the earthquake or larger vibration (such as train or truck passing) occurs, the piston moves up and down, which consumes a lot of energy, thereby greatly reducing the damage of the earthquake or vibration to the structural parts.

[0008] Preferably, the inner surface of the piston is provided with a cylindrical inner groove, and the outer surface of the piston is in sliding connection with the inner wall of the outer connecting base plate to form a sealed chamber.
[0009] Preferably, the positioning sealing groove of the piston is provided with four sealing grooves, the second sealing ring adopts a Y-shaped sealing ring structure, and two second sealing rings are symmetrically installed in the positioning sealing groove of the piston.

Figure 6 As shown, four positioning sealing grooves 301 of the piston 3 are arranged, the second sealing ring 9 adopts a Y-shaped sealing ring structure, and two second sealing rings 9 are symmetrically arranged in the positioning sealing groove 301 in the middle of the outer surface of the piston 3, and the other two first sealing rings 8 are arranged in the positioning sealing groove 301 at both ends, the inner wall 202 of the outer connecting base plate 2 is sealingly connected with the piston 3, a cylindrical inner groove 303 is arranged on the inner surface of the piston 3, and a positioning boss 302 is arranged at the center of the cylindrical inner groove 303, at this time, the outer surface of the piston 3 is slidingly connected with the inner wall 202 of the outer connecting base plate 2 to form a sealed chamber 12, the valve core assembly 6 for inflating the inner wall 202 of the outer connecting base plate 2 and the air pressure gauge assembly 7 for detecting the air pressure are arranged on the outer connecting base plate 2, the valve core assembly 6 and the air pressure gauge assembly 7 are communicated with the sealed chamber 12, the accuracy of the inflation pressure in the sealed chamber 12 is ensured, and the inflation pressure value is set according to the rated gravity load.
[0029] Example 2
[0030] This embodiment has a basically the same main structure as Embodiment 1, such as... Figure 3 As shown, a first compression spring 10 and a second compression spring 11 are respectively provided at the bottom of the cylindrical inner groove 303 on the piston 3. One end of the first compression spring 10 and the second compression spring 11 abuts against the outer connecting base plate 2. The outer diameter of the first compression spring 10 is adapted to the diameter of the cylindrical inner groove 303, and the inner diameter of the second compression spring 11 is adapted to the diameter of the positioning boss 302.

[0031] Therefore, the shock-absorbing bearing structure used in this invention is simple. Its high-pressure gas avoids the environmental pollution and aging issues associated with traditional rubber seismic isolation bearings, which lead to unstable quality. When an earthquake or significant vibration occurs, the piston consumes a large amount of energy during its up-and-down movement, thus reducing the destructive effects of earthquakes and vibrations on the structure. After the earthquake or vibration subsides, the piston returns to its original position. Furthermore, this invention employs two implementation schemes: one using pure high-pressure gas and the other using high-pressure gas with a spring. By adding a compression spring to the sealed chamber, the load-bearing capacity of the shock-absorbing base is effectively increased, ensuring its load-bearing stability.
