Therefore, countries around the world are committed to doing a good job in earthquake-resistant engineering and disaster reduction. Seismic isolation technology is a new form of earthquake-resistant building structure. By setting seismic isolation pads on the top of a certain column of the house, the earthquake effect is prevented from being transmitted upward, thereby achieving the effect of weakening the earthquake response of the structure.

[0036] The side wall of the installation groove 3 is provided with a grouting hole 7 and an exhaust hole.

[0037] When the present invention is working, firstly, the positioning mechanisms at both ends of the seismic isolation device are respectively inserted into the mounting grooves 3 of the upper concrete column 1 and the lower concrete column 2, and the positioning and fixing between the upper concrete and the lower concrete are realized by the positioning mechanisms, and the pressure buffer components are respectively connected to the two mounting sleeves 4, and the elastic seismic isolation components are installed between the two mounting sleeves 4, and the fixing plates 5 are respectively fixed on the upper concrete column 1 and the lower concrete column 2, and the rubber vibration isolation column 6 is installed between the fixing plates 5, and the notch of the mounting groove 3 is blocked, and the grouting is blocked through the grouting hole 7, and the gas in the mounting groove 3 is discharged through the exhaust hole, and the grouting is completed to close the grouting hole 7, and the concrete solidifies to complete the device installation, and the vibration is generated between the upper concrete column 1 and the lower concrete column 2, and the distance changes, and the pressure on the rubber vibration isolation column 6 is shared by the elastic seismic isolation component and the pressure buffer component, thereby improving the working life and compressive resistance of the rubber vibration isolation column 6.

[0040] The positioning mechanism is in contact with the partition plate 8 .

[0041] A further optimized solution is provided, wherein the positioning mechanism includes a positioning rod 11 rotatably connected to the outer wall of the mounting sleeve 4, a connecting rod 12 is rotatably connected to the side of the positioning rod 11, one end of the connecting rod 12 is rotatably connected to a slider 13, a sliding groove 14 is provided on the outer wall of the mounting sleeve 4 along the axial direction, the slider 13 is slidably connected in the sliding groove 14, a fixed block 15 is fixedly connected in the sliding groove 14, the fixed block 15 is located between the slider 13 and the positioning rod 11, a sliding rod 16 is horizontally slidably connected to the fixed block 15, one end of the sliding rod 16 is fixedly connected to the side of the slider 13, a first spring 17 is sleeved on the sliding rod 16, and the two ends of the first spring 17 are respectively fixedly connected to the slider 13 and the fixed block 15; the positioning rod 11 is in contact with the partition 8.

[0042] A further optimized solution is that an arc groove is opened on the outer wall of the mounting sleeve 4, one end of the positioning rod 11 is fixedly connected to a ratchet 18, the ratchet 18 is rotatably connected in the arc groove, a latch tooth is installed in the arc groove, and the latch tooth and the ratchet 18 are limitedly matched.

[0043] According to a further optimization scheme, a positioning block 19 is fixedly connected to the inner wall of the mounting groove 3, a gap is provided between the positioning block 19 and the partition 8, one end of the positioning rod 11 is inserted into the gap, and a side of the positioning block 19 close to the positioning rod 11 is provided as an arc surface.

[0044] During operation, a small angle is formed between the positioning rod 11 and the mounting sleeve 4 in the initial state. When the positioning rod 11 enters the mounting groove 3 and abuts against the partition 8 in the mounting groove 3, the first spring 17 is continuously stretched and the slider 13 slides away from the positioning rod 11. The positioning rod 11 opens and is inserted between the positioning block 19 and the partition 8.

[0046] The annular groove 21 is provided so that the mounting sleeve 4 can be plugged into the connecting pipe 20 to form a connection between the two pipes. At the same time, a second spring 22 is provided in the annular groove 21. The second spring 22 assists in forming a buffer in the middle position, thereby reducing the pressure on the rubber vibration isolation column 6. At the same time, the sealing rubber provided at the end can prevent the pressurized liquid from entering the annular groove 21 and causing corrosion of the spring.

[0050] The length of the installation pipe 25 is greater than the distance between the partition plate 8 and the end portion of the installation groove 3 , and is less than the straight-line distance between the partition plate 8 and the connecting pipe 20 .

[0051] The deformable pressure bag 10 can be connected to the rubber vibration isolation column 6 through the setting of the mounting tube 25. The pressure liquid in the rubber vibration isolation column 6 can enter the deformable pressure bag 10 through the through hole 23 on the connecting tube 20, the mounting sleeve 4, and the mounting tube 25. The deformable pressure bag 10 is made of high-pressure resistant material, and the inner cavity is also filled with a certain amount of pressure liquid, so that the deformable pressure bag 10 is at the critical value of deformation, and the contraction effect of high-pressure resistance is used to achieve liquid pressure buffering. The distance between the upper concrete column 1 and the lower concrete column 2 changes due to vibration, thereby compressing the rubber vibration isolation column 6, and the pressure liquid in the rubber vibration isolation column 6 is converted through the middle connecting part, thereby eliminating the acting force. At the same time, in this embodiment, a sealing baffle ring is fixed on the inner wall of the mounting sleeve 4. The sealing baffle ring is made of rubber material and abuts against the end of the mounting tube 25. The mounting tube 25 is fixed to the partition 8 to ensure the sealing of the overall liquid channel.
