Fig. 1 is a construction view illustrating a method for replacing a seismic isolation device according to the present invention. As shown in fig. 1, construction is specifically shown in which a new second seismic isolation apparatus 100 is used to replace a first seismic isolation apparatus 200 to be replaced.

First, the height of the first seismic isolation device 200 to be replaced, which is installed inside the building foundation 201, is measured. Meanwhile, the coupling assembly 220 for fixedly coupling the first seismic isolation apparatus 200 is measured and positioned to measure a specific position of the coupling assembly 220.

Thereafter, a second seismic isolation apparatus 100 for replacing the first seismic isolation apparatus 200 is manufactured, and the position of the mounting hole 126 (see fig. 3) of the second seismic isolation apparatus 100 is determined based on the specific position of the connecting assembly 220 measured on the first seismic isolation apparatus 200.

Fig. 2 shows the structure of the second seismic isolation apparatus 100. The second seismic isolation apparatus 100 will be described with reference to fig. 2.

As shown in fig. 2, the second seismic isolation apparatus 100 includes a mount body 110. In one embodiment, the holder body 110 is configured in a cylindrical shape. The size of the holder body 110 is set according to actual needs. The support body 110 may be, for example, a lead isolation rubber support, a natural isolation rubber support, or a high damping isolation rubber support. The support body 110 is provided with the sliding mechanism 120, and the sliding mechanism 120 can enable the second vibration isolation device 100 to replace the original first vibration isolation device 200 in the building foundation 201 under the condition that the internal structure of the building foundation 201 is not damaged, so that the stability of the structure of the building foundation 201 is ensured, and the replacement and installation efficiency of the second vibration isolation device 100 is improved.

According to the present invention, the sliding mechanisms 120 are symmetrically disposed at the upper and lower ends of the holder body 110. As shown in fig. 2, the sliding mechanism 120 includes a connecting plate 121 for fixed connection with an axial end of the holder body 110. The connection plate 121 is configured in a square plate shape, and a side length of the connection plate 121 is greater than a diameter of the holder body 110. In one embodiment, one end surface of the connection plate 121 is adhesively attached to one end of the holder body 110 to form a fixed connection with the holder body 110.

As shown in fig. 2, skid mechanism 120 further includes embedment plate 122. In one embodiment, the embedded plate 122 has a square plate shape, and the side length of the connecting plate 121 is greater than the diameter of the holder body 110. A sliding material 123 is provided between the connecting plate 121 and the embedment plate 122, and one end surface of the sliding material 123 is in contact with one end surface of the connecting plate 121. In one embodiment, the sliding material 123 is in the shape of a square plate, and the side length of the sliding material 123 is greater than the diameter of the holder body 110. The sliding material 123 is made of a pressure-resistant polymer material. In one embodiment, the glide material 123 is made of a material including a polytetrafluoroethylene material and a modified ultra high molecular weight polyethylene material. The embedded plate 122 is used as a positioning plate for replacement construction, and the embedded plate 122 is installed when the buttress is poured and cannot be detached after installation.

According to the invention, a sliding panel 124 is arranged between the sliding material 123 and the embedded plate 122, and the upper end surface and the lower end surface of the sliding panel 124 are respectively contacted with the sliding material 123 and the end surface of the embedded plate 122. In one embodiment, the glide panel 124 is square plate shaped, and the side length of the glide panel 124 is greater than the diameter of the mount body 110. The slip panel 124 is made of a material having a low coefficient of friction characteristic. In one embodiment, the slip panel 124 is made of a smooth-surfaced steel plate. In the present embodiment, a plurality of grease reservoirs 128 are provided on the end surface of the sliding member 123 in contact with the sliding surface plate 124, and grease is provided in the grease reservoirs 128. Preferably, the grease is silicone grease. In one embodiment, the grease reservoir 128 is arranged in a circular shape and evenly distributed over the glide material 123. The grease can effectively reduce the friction between the slip panel 124 and the slip material 123. In a normal state, the sliding material 123 and the sliding panel 124 do not affect the shock absorbing and isolating effects of the second shock-isolating device 100. When the second seismic isolation device 100 is deviated or needs to be replaced, the bolts of the connecting assembly 220 are removed, and at this time, a small horizontal force is applied to the second seismic isolation device 100, so that the sliding material 123 and the sliding panel 124 are relatively displaced, thereby achieving the purposes of correcting the deviation and replacing. After the second seismic isolation device 100 is corrected for deviation or replaced, the second seismic isolation device 100 is reconnected to the abutment by the bolts of the connection assembly 220.

According to the present invention, the connection plate 121, the sliding material 123, the sliding panel 124 and the embedded plate 122 form a fixed connection through the connection assembly 220. In one embodiment, the connection assembly 220 may employ a bolt-in-sleeve tendon assembly. The connecting plate 121, the sliding material 123, the sliding panel 124 and the embedded plate 122 are all provided with a plurality of mounting holes 126 for the connecting assembly 220 to pass through. The position of the mounting hole 126 is set according to the position of the coupling assembly 220 on the first seismic isolation device 200 to be replaced. In one embodiment, the mounting holes 126 are respectively disposed at positions close to four corners of the connecting plate 121, the sliding material 123, the sliding panel 124 and the embedded plate 122, and each of the connecting plate 121, the sliding material 123, the sliding panel 124 and the embedded plate 122 is provided with 8 mounting holes 126, and the 8 mounting holes 126 are uniformly distributed at positions of four corners of the connecting plate 121, the sliding material 123, the sliding panel 124 and the embedded plate 122. The connecting assembly 220 sequentially penetrates through the connecting plate 121, the sliding material 123, the sliding panel 124 and the mounting hole 126 of the embedded plate 122 so that the connecting plate 121, the sliding material 123, the sliding panel 124 and the embedded plate 122 form a fixed connection. Thus, the second seismic isolation device 100 is completed.

The second seismic isolation apparatus 100 according to the present invention can isolate or dissipate seismic energy and can improve self-anti-deflection capability. The glide mechanism 120 in the second seismic isolation device 100 has an extremely low friction coefficient, and can take out the first seismic isolation device 200 to be replaced under the condition that the upper building does not need to be jacked, so that the replacement operation is simple and convenient, the replacement difficulty can be reduced, and the use performance and the replacement efficiency of the second seismic isolation device 100 are remarkably improved. In addition, the second seismic isolation device 100 has a stable structure, high construction efficiency and low construction cost.

After the second vibration isolation device 100 is manufactured, the vibration isolation supporting position in the building foundation 201 where the first vibration isolation device 200 is installed is cleaned, and therefore sundries are removed and polished when the vibration isolation supporting position is moved out and enters the channel.

In this embodiment, the base plates 210 are laid in the directions of the entrance and exit of the seismic isolation support positions, respectively. In one embodiment, the backing plate 210 is made of a smooth-surfaced steel plate, and the coefficient of friction between the backing plate 210 and the sliding material 123 is less than 0.03. The pad 210 is used to guide the removal work of the first seismic isolation apparatus 200 and the introduction work of the second seismic isolation apparatus 100 to improve the replacement efficiency.

In this embodiment, the pre-embedded plate and the sliding panel of the first seismic isolation device 200 to be replaced are fixed to the abutment, and only the support body and the connecting plate portion are replaced. Therefore, the sliding panel and the sliding material form a sliding structure, so that the friction force is reduced, and the replacement is facilitated.

Thereafter, the first seismic isolation apparatus 200 is removed from the seismic isolation support position, and the second seismic isolation apparatus 100 is laid out to the seismic isolation support position. In one embodiment, the first seismic isolation device 200 is drawn out of the seismic isolation support position in the direction of the base plate 210, the second seismic isolation device 100 is drawn into the seismic isolation support position in the direction of the base plate 210, and the drawing of the second seismic isolation device 100 are performed synchronously. The directions indicated by arrows in fig. 1 are the direction in which the first seismic isolation device 200 is drawn out and the direction in which the second seismic isolation device 100 is drawn in.

In this embodiment, before the second seismic isolation device 100 is pulled out of the seismic isolation support position, the positioning bolts for fixedly mounting the first seismic isolation device 200 to be replaced are removed. And, before the second seismic isolation apparatus 100 is introduced into the seismic isolation support position, the second seismic isolation apparatus 100 is compressed so that the height of the second seismic isolation apparatus 100 is smaller than the height of the first seismic isolation apparatus 200. In order to ensure that the parts of the second seismic isolation device 100 are dislocated in the guiding process, the pre-pressed second seismic isolation device 100 is fastened to ensure that the parts of the second seismic isolation device 100 are stably connected. Therefore, the second vibration isolation device 100 can be conveniently guided into the vibration isolation supporting position, the replacement construction difficulty is reduced, and the replacement construction efficiency is improved.

In one embodiment, in order to facilitate the guiding of the second seismic isolation device 100 into the seismic isolation support position, before the second seismic isolation device 100 is guided into the seismic isolation support position, the abutment in the entering direction of the seismic isolation support position of the building foundation 201 may be further polished to form a bell-mouth-shaped mounting opening. The horn-mouth-shaped mounting opening facilitates the leading-in of the second shock isolation device 100 into a shock isolation supporting position, so that the leading-in construction difficulty can be further reduced, and the replacement construction efficiency is improved.

In addition, in order to facilitate the traction of the second seismic isolation device 100 to guide into the seismic isolation support position, before the second seismic isolation device 100 is guided into the seismic isolation support position, the fillet or bevel treatment can be performed on each side of the contact surface of the sliding material 123 and the sliding panel 124. The structure of the sliding material 123 can also facilitate the second seismic isolation device 100 to guide in the seismic isolation supporting position, so that the guide-in construction difficulty can be further reduced, and the replacement construction efficiency can be improved.

Finally, the second seismic isolation device 100 is fixedly installed by the connection assembly 220. The connecting assembly 220 is installed in the installation hole of the second seismic isolation apparatus 100, thereby forming a fixed installation for the second seismic isolation apparatus. Thereby, replacement of the first seismic isolation device 200 is completed.

According to the replacing method for the shock insulation device, the original shock insulation device can be replaced under the condition that the original internal structure of the building is not damaged, the shock insulation performance of the shock insulation device on the building is ensured, the safety of the upper structure of the building and personnel and equipment in the building is effectively ensured, and the normal operation of the building is ensured. In the replacement process, the bolt hole position of the shock isolation device to be replaced is measured, and the matched new shock isolation device is manufactured, so that the new shock isolation device can be accurately positioned and installed. The new seismic isolation apparatus has good anti-deflection capability, which can isolate or dissipate seismic energy. And, new shock isolation device is equipped with glide machanism to make its change easy operation convenient, reduced the change degree of difficulty, improved shock isolation device's suitability and change efficiency. In addition, the evacuation construction of the seismic isolation device to be replaced and the entering and laying construction of a new seismic isolation device are carried out simultaneously, so that the replacement construction is convenient and quick, the replacement construction efficiency is greatly improved, and the positioning accuracy of the new seismic isolation device is effectively ensured.

The foregoing is merely an illustrative embodiment of the present invention, and any equivalent changes and modifications made by those skilled in the art without departing from the spirit and principle of the present invention should fall within the protection scope of the present invention.
