Description

Technical Field

[0001] This invention belongs to the field of building seismic isolation rubber bearing disassembly and assembly technology, and in particular relates to a building seismic isolation rubber bearing disassembly and assembly device and its disassembly and assembly method. Background Technology

[0002] Seismic isolation rubber bearings are the most widely used and technologically mature seismic isolation devices. They form an isolation layer by placing the device at the base of the building or at a specific location, connecting the superstructure to the substructure. This isolates or dissipates seismic energy, preventing or reducing its transmission to the upper structure, effectively ensuring the safety of the upper structure and its internal personnel and equipment. It does not affect the normal operation of indoor equipment, significantly reducing earthquake damage to the structure and guaranteeing the safety of the structure, people, and property. Seismic isolation rubber bearings are both an important component of the structural load-bearing structure and a key component for dissipating seismic energy, playing a crucial role in building safety.

[0003] Under normal service conditions, building seismic isolation rubber bearings can guarantee a service life similar to that of the main structure. However, in situations such as fire, earthquake, corrosion, or harsh working environments, the bearing performance may decrease or be lost. Building seismic isolation rubber bearings are made by alternating layers of thin steel plates and thin rubber plates, vulcanized under high temperature and pressure. Rubber is flammable and easily combusts in the event of a fire. Since seismic isolation devices are generally directly exposed within the building structure, the rubber bearings will be damaged in a fire.

[0004] During use, buildings continuously bear vertical loads. Simultaneously, when subjected to wind loads, strong earthquakes, and repeated aftershocks, the repeated mechanical stress causes rubber molecular chains to break, generating free radicals. This triggers oxidation chain reactions, forming a mechanochemical process, and is also prone to ozone cracking under stress. Furthermore, underground structures often suffer from poor ventilation and humidity. Prolonged exposure to humid environments causes rubber to undergo gradual physical and chemical changes, leading to a decline in its properties and eventual loss of usability—a phenomenon known as rubber aging. Rubber aging is often accompanied by significant phenomena such as softening, stickiness, brittleness, hardening, cracking, mold growth, loss of gloss, and color changes. Physically, rubber exhibits changes in swelling and rheological properties; mechanically, tensile strength, elongation at break, impact strength, flexural strength, compressibility, and elasticity decrease, all affecting the load-bearing capacity of seismic isolation rubber bearings. Therefore, when the service life of building seismic isolation rubber bearings exceeds their design life, or when one or more of the above conditions occur simultaneously, they must be replaced promptly to ensure the safety of the building structure, people, and property.

[0005] Therefore, there is currently a lack of a simple and reasonably designed disassembly and assembly device and method for seismic isolation rubber bearings that can quickly, safely and conveniently disassemble and assemble seismic isolation rubber bearings that have lost their load-bearing function due to fire, earthquake, harsh working environment or exceeding the design life.

[0021] Meanwhile, this invention also discloses a simple and rationally designed method for disassembling and assembling a seismic isolation rubber bearing device for buildings, characterized by the following steps:

[0022] The method includes the following steps:

[0023] Step 1: Spray kerosene at the connection point of the support to be dismantled.

[0024] Step 101: The upper flange of the support to be dismantled is connected to the upper structure, and the lower flange of the support to be dismantled is connected to the lower structure; wherein, the upper flange is connected to the upper embedded steel plate at the bottom of the upper structure, and the lower flange is connected to the lower embedded steel plate at the top of the lower structure; the support to be dismantled is a building seismic isolation rubber bearing.

[0025] Step 102: Spray kerosene around the contact surface between the upper flange and the upper embedded steel plate, as well as on the connecting bolts between the upper flange and the upper embedded steel plate; and spray kerosene around the contact surface between the lower flange and the lower embedded steel plate, as well as on the connecting bolts between the lower flange and the lower embedded steel plate.

[0026] Step 2: Install guide mechanisms on the upper and lower structures of the support to be dismantled.

[0027] Step 201: Install two parallel upper L-shaped guide members on the upper structure; wherein, the horizontal parts of the two upper L-shaped guide members are installed on the upper structure by upper expansion bolts, and the vertical parts of the two upper L-shaped guide members are attached to the side of the upper flange of the support to be disassembled.

[0028] Step 202: Install two parallel lower L-shaped guide members on the lower structure; wherein, the horizontal parts of the two lower L-shaped guide members are installed on the lower structure by lower expansion bolts, and the vertical parts of the two upper L-shaped guide members are attached to the side of the lower flange of the support to be disassembled.

[0029] Step 3: Install hydraulic jacking devices on both sides of the support to be dismantled.

[0030] A hydraulic jacking device is installed between the upper and lower structures on both sides of the support to be dismantled; wherein, the top of the hydraulic jacking device is equipped with an upper liner, the bottom of the hydraulic jacking device is equipped with a lower liner, the upper liner is attached to the bottom surface of the upper structure, and the lower liner is attached to the top surface of the lower structure.

[0031] Step 4: Install the disassembly / removal device between two adjacent seismic isolation rubber bearings:

[0032] Step 401: Use a self-propelled electric hydraulic lifting platform to lift the disassembly and assembly device to the same height between the support to be disassembled and another support to be disassembled; wherein, the disassembly and assembly cylinders are arranged close to the support to be disassembled.

[0033] Step 402: Operate the hydraulic jacking device to raise the distance between the top surface of the lower embedded steel plate and the bottom surface of the upper embedded steel plate to be 4 mm to 5 mm greater than the height of the new support. Remove the connecting bolts between the upper flange and the upper embedded steel plate, and the connecting bolts between the lower flange and the lower embedded steel plate.

[0034] Step 403: Operate the locking mechanism to release the locking of the right guide rod, and operate the piston rod of the adjusting cylinder to extend. The extension of the piston rod of the adjusting cylinder drives the right end disassembly head to move closer to another support to be disassembled through the adjusting cylinder connecting seat. At the same time, the right end disassembly head drives the right guide rod to slide along the right guide sleeve and the middle guide sleeve.

[0035] Step 404: Continue until the upper and lower working surfaces of the right end disassembly head support the upper and lower flange sides of another support to be disassembled;

[0036] Step 405: Operate the locking mechanism to lock the right guide rod;

[0037] Step 5: Remove the support to be removed on the left end:

[0038] Step 501: Extend the piston rod of the disassembly and assembly cylinder. The extension of the piston rod of the disassembly and assembly cylinder will drive the disassembly and assembly connecting seat and the left disassembly and assembly head to move until the working surface and the lower working surface of the left disassembly and assembly head respectively fit against the side of the upper flange and the lower flange of the support to be disassembled.

[0039] Step 502: Operate the piston rod of the disassembly cylinder to continue to extend and push the support to be disassembled away from the adjusting cylinder along the two upper L-shaped guides and the two lower L-shaped guides until the support to be disassembled is separated from the lower and upper structures; Meanwhile, another self-propelled electric hydraulic lifting platform is set on the left side between the lower and upper structures to support the support to be disassembled.

[0040] Step 503: Operate the piston rod of the disassembly and assembly cylinder to retract, grind the rust spots on the upper surface of the lower embedded steel plate and the lower surface of the upper embedded steel plate to make the surface of the embedded steel plate smooth and flat, and apply grease.

[0041] Step 504: After the support to be dismantled is placed on the ground, another self-propelled electric hydraulic lifting platform supports the new support and lifts it to the left side of the lower and upper structures.

[0042] Step Six: Installation and Disassembly of the Hydraulic Lifting Device for the New Support:

[0043] Step 601: Following the method described in step 501, continue until the left disassembly head and the new support are in contact. The threaded connection hole of the upper disassembly connecting plate in the left disassembly head and the upper flange are connected by the upper connecting bolts. The threaded connection hole of the lower disassembly connecting plate in the left disassembly head and the lower flange are connected by the lower connecting bolts. A pad is installed between the upper adjustment surface of the upper disassembly connecting plate and the bottom surface of the upper flange, and between the lower adjustment surface of the lower disassembly connecting plate and the top surface of the lower flange.

[0044] Step 602: Operate the piston rod of the disassembly and assembly cylinder to retract, which will drive the new support to move to the right along the two upper L-shaped guides and the two lower L-shaped guides, close to the adjusting cylinder, until the new support moves to the position where the lower and upper pre-embedded steel plates have been disassembled. Then, operate the left end disassembly and assembly head to disconnect from the new support.

[0045] Step 603: Operate the hydraulic jacking device to retract, so that the distance between the top surface of the lower embedded steel plate and the bottom surface of the upper embedded steel plate is reset, and remove the hydraulic jacking device from between the upper and lower structures.

[0046] Step 604: Install connecting bolts between the upper flange and the upper embedded steel plate of the new support, and install lower connecting bolts between the lower flange and the lower embedded steel plate of the new support.

[0047] Step 7: Operate the self-propelled electric hydraulic lifting platform to rotate the disassembly and assembly device 180° so that the disassembly and assembly cylinder is positioned close to another support to be disassembled. Repeat steps 1 to 6 to disassemble the other support to be disassembled on the right end and install the new support.

[0048] The above-mentioned method for disassembling and assembling a seismic isolation rubber bearing is characterized in that: in step 403, the locking mechanism is operated to release the locking of the right guide rod, and the specific process is as follows:

[0049] The rotation of the operating handle drives the gear to rotate via the shaft, and the rotation of the gear drives the positioning pin to move away from the right guide rod via the rack, so that the first tooth of the positioning pin and the second tooth of the right guide rod are moved away from each other.

[0050] The specific process of locking the right guide rod by operating the locking mechanism in step 405 is as follows:

[0051] The rotation of the operating handle drives the gear to rotate in the opposite direction via the shaft. The reverse rotation of the gear drives the locating pin to engage with the right guide rod via the rack, so that the first tooth of the locating pin and the second tooth of the right guide rod are engaged.

[0052] The above-mentioned method for disassembling and assembling a seismic isolation rubber bearing disassembly and assembly device is characterized in that: in step 501, when the piston rod of the disassembly and assembly cylinder extends and pushes the bearing to be disassembled through the disassembly and assembly connecting seat and the left end disassembly and assembly head, the left guide rod connected to the left end disassembly and assembly head slides and guides along the left guide sleeve.

[0053] In step 403, when the piston rod of the adjusting cylinder extends and drives the right end disassembly head to move through the adjusting cylinder connecting seat, the right guide rod connected to the right end disassembly head slides and is guided along the right guide sleeve and the middle guide sleeve.

[0054] Compared with the prior art, the present invention has the following advantages:

[0055] 1. The building seismic isolation rubber bearing disassembly and assembly device of the present invention is reasonably designed and easy to operate, which meets the requirements of convenient construction operation for disassembly and assembly of building seismic isolation rubber bearings.

[0056] 2. The present invention is equipped with a disassembly cylinder and a left-end disassembly head. This is so that after the left-end disassembly head and the support to be disassembled are in contact, the extension of the disassembly cylinder provides thrust to push the support to be disassembled away from the lower and upper pre-embedded steel plates, thereby realizing the disassembly of the support to be disassembled. In addition, when the left-end disassembly head and the new support are connected, the retraction of the disassembly cylinder provides tension, thereby pulling the new support between the lower and upper pre-embedded steel plates for installation, which is convenient to operate.

[0057] 3. The present invention is equipped with an adjustable hydraulic cylinder and a right-end disassembly head. On the one hand, it is to adapt to the different spacing between two adjacent supports to be disassembled, thereby improving the adaptability range. On the other hand, it is to connect the right-end disassembly head with another support to be disassembled, thereby bearing the reaction force of the disassembly cylinder thrust and ensuring that the disassembly cylinder thrust is applied to the support to be disassembled.

[0058] 4. The present invention is equipped with a left guide mechanism, which not only guides the left end of the disassembly head as it extends and pushes it to move, so as to ensure that the left end of the disassembly head moves accurately and avoids the support to be disassembled from shifting, which would cause difficulties in subsequent disassembly, but also increases the stability of the piston rod of the disassembly cylinder under reverse pressure.

[0059] 5. The present invention is provided with a right guide mechanism, which not only guides the movement of the right end disassembly head as the adjusting cylinder extends, so as to ensure that the movement path of the right end disassembly head is accurate and that the right end disassembly head is accurately connected to the other support to be disassembled, but also bears the reverse pressure of the disassembly cylinder and transmits it to the other support to be disassembled.

[0060] 6. The disassembly and assembly method of the building seismic isolation rubber bearing disassembly and assembly device of the present invention is convenient to construct. First, kerosene is sprayed on the connecting bolts of the bearing to be disassembled and around the upper and lower flanges. Second, guide mechanisms are installed on the upper and lower structures of the bearing to be disassembled, hydraulic jacking devices are installed on both sides of the bearing to be disassembled, and disassembly and assembly devices are installed between two adjacent seismic isolation rubber bearings. Next, the left end of the bearing to be disassembled is disassembled, and the new bearing is installed and disassembled by the hydraulic jacking device. Then, the self-propelled electric hydraulic lifting platform is operated to drive the disassembly and assembly device to rotate, and the other bearing to be disassembled is disassembled. It has good adaptability and is convenient to operate.

[0061] In summary, the present invention is reasonably designed and easy to construct, and can quickly, safely and conveniently disassemble and assemble seismic isolation rubber bearings that have lost their load-bearing function due to fire, earthquake, harsh working environment or exceeding the design life.

[0110] In this embodiment, one end of the spring 12-2 is inserted into the bottom of the receiving hole of the positioning pin 12-1 to limit the contraction direction of the spring 12-2 and improve the accuracy of the spring 12-2 driving the positioning pin 12-1 to move.

[0111] In this embodiment, during actual use, the side wall of the shaft portion 12-7 is provided with a limiting groove for the insertion of the screw 12-5, so that the insertion of the screw 12-5 only restricts the axial displacement of the shaft portion 12-7 and does not affect the rotation of the shaft portion 12-7.

[0112] In this embodiment, during actual use, one end of the left guide rod 10 is connected to the disassembly head plate 7-4.

[0113] like Figures 5 to 6 The disassembly and assembly method of the building seismic isolation rubber bearing disassembly and assembly device shown includes the following steps:

[0114] Step 1: Spray kerosene at the connection point of the support to be dismantled.

[0115] Step 101: The upper flange 4-1 of the support to be dismantled 4 is connected to the upper structure 30, and the lower flange 4-2 of the support to be dismantled 4 is connected to the lower structure 1; wherein, the upper flange 4-1 is connected to the upper embedded steel plate 30-1 at the bottom of the upper structure 30, and the lower flange 4-2 is connected to the lower embedded steel plate 1-1 at the top of the lower structure 1; the support to be dismantled 4 is a building seismic isolation rubber bearing;

[0116] Step 102: Spray kerosene around the contact surface between the upper flange 4-1 and the upper embedded steel plate 30-1, as well as on the connecting bolts 3 between the upper flange 4-1 and the upper embedded steel plate 30-1; and spray kerosene around the contact surface between the lower flange 4-2 and the lower embedded steel plate 1-1, as well as on the connecting bolts 3 between the lower flange 4-2 and the lower embedded steel plate 1-1.

[0117] Step 2: Install guide mechanisms on the upper and lower structures of the support to be dismantled.

[0118] Step 201: Install two parallel upper L-shaped guide members 5-1 on the upper structure 30; wherein, the horizontal parts of the two upper L-shaped guide members 5-1 are installed on the upper structure 30 by upper expansion bolts, and the vertical parts of the two upper L-shaped guide members 5-1 are attached to the side of the upper flange 4-1 of the support to be disassembled.

[0119] Step 202: Install two parallel lower L-shaped guide members 5-2 on the lower structure 1; wherein, the horizontal parts of the two lower L-shaped guide members 5-2 are installed on the lower structure 1 by lower expansion screws 2, and the vertical parts of the two upper L-shaped guide members 5-1 are attached to the side of the lower flange 4-2 of the support to be disassembled.

[0120] Step 3: Install hydraulic jacking devices on both sides of the support to be dismantled.

[0121] A hydraulic jacking device 6 is installed between the upper structure 30 and the lower structure 1 on both sides of the support to be dismantled 4; wherein, the top of the hydraulic jacking device 6 is provided with an upper liner 6-1, the bottom of the hydraulic jacking device 6 is provided with a lower liner 6-2, the upper liner 6-1 is attached to the bottom surface of the upper structure 30, and the lower liner 6-2 is attached to the top surface of the lower structure 1.

[0122] Step 4: Install the disassembly / removal device between two adjacent seismic isolation rubber bearings:

[0123] Step 401: Use a self-propelled electric hydraulic lifting platform to lift the disassembly and assembly device to the same height between the support 4 to be disassembled and another support 19 to be disassembled; wherein, the disassembly and assembly cylinder 26 is arranged close to the support 4 to be disassembled.

[0124] Step 402: Operate the hydraulic jacking device 6 to raise the distance between the top surface of the lower embedded steel plate 1-1 and the bottom surface of the upper embedded steel plate 30-1 by 4 mm to 5 mm more than the height of the new support. Remove the connecting bolts between the upper flange 4-1 and the upper embedded steel plate 30-1, and the connecting bolts between the lower flange 4-2 and the lower embedded steel plate 1-1.

[0125] Step 403: Operate the locking mechanism to release the locking of the right guide rod 23, and operate the adjusting cylinder piston rod 18 of the adjusting cylinder 15 to extend. The extension of the adjusting cylinder piston rod 18 drives the right end disassembly head 20 to move closer to another support 19 to be disassembled through the adjusting cylinder connecting seat 21. At the same time, the right end disassembly head 20 drives the right guide rod 23 to slide along the right guide sleeve 24 and the middle guide sleeve 16.

[0126] Step 404: Until the upper working surface 7-31 and the lower working surface 7-32 of the right end disassembly head 20 support the upper and lower flange sides of another support 19 to be disassembled;

[0127] Step 405: Operate the locking mechanism to lock the right guide rod 23;

[0128] Step 5: Remove the support to be removed on the left end:

[0129] Step 501: The piston rod 29 of the disassembly and assembly cylinder 26 is extended. The extension of the piston rod 29 drives the disassembly and assembly connecting seat 8 and the left disassembly and assembly head 7 to move until the upper working surface 7-31 and the lower working surface 7-32 of the left disassembly and assembly head 7 respectively fit against the sides of the upper flange 4-1 and the lower flange 4-2 in the support to be disassembled 4.

[0130] Step 502: Operate the piston rod 29 of the disassembly cylinder to continue to extend and push the support 4 to be disassembled away from the adjusting cylinder 15 along the two upper L-shaped guides 5-1 and the two lower L-shaped guides 5-2 until the support 4 to be disassembled is separated from the lower structure 1 and the upper structure 30; wherein, another self-propelled electric hydraulic lifting platform is set on the left side between the lower structure 1 and the upper structure 30 to support the support 4 to be disassembled;

[0131] Step 503: Operate the disassembly and assembly cylinder 26 to retract the piston rod 29, grind the rust spots on the upper surface of the lower embedded steel plate 1-1 and the lower surface of the upper embedded steel plate 30-1 to make the embedded steel plate surface smooth and flat, and apply grease.

[0132] Step 504: After the other self-propelled electric hydraulic lifting platform lowers the support 4 to be dismantled to the ground, it supports the new support and lifts it to the left side of the lower structure 1 and the upper structure 30.

[0133] Step Six: Installation and Disassembly of the Hydraulic Lifting Device for the New Support:

[0134] Step 601: Following the method described in step 501, continue until the left disassembly head 7 and the new support are in contact. The threaded connection hole 7-5 of the upper disassembly connecting plate 7-2 in the left disassembly head 7 and the upper flange 4-1 are connected by the upper connecting bolts. The threaded connection hole 7-5 of the lower disassembly connecting plate 7-1 in the left disassembly head 7 and the lower flange 4-2 are connected by the lower connecting bolts. A pad is placed between the upper adjustment surface 7-21 of the upper disassembly connecting plate 7-2 and the bottom surface of the upper flange 4-1, and between the lower adjustment surface 7-11 of the lower disassembly connecting plate 7-1 and the top surface of the lower flange 4-2.

[0135] Step 602: Operate the piston rod 29 of the disassembly and assembly cylinder 26 to retract, causing the new support to move to the right along the two upper L-shaped guides 5-1 and the two lower L-shaped guides 5-2 close to the adjusting cylinder 15 until the new support moves to the position of the disassembled support of the lower embedded steel plate 1-1 and the upper embedded steel plate 30-1, and then operate the left end disassembly and assembly head 7 to disconnect from the new support;

[0136] Step 603: Operate the hydraulic jacking device 6 to retract, so that the distance between the top surface of the lower embedded steel plate 1-1 and the bottom surface of the upper embedded steel plate 30-1 is reset, and remove the hydraulic jacking device 6 from between the upper structure 30 and the lower structure 1.

[0137] Step 604: Install connecting bolts between the upper flange of the new support and the upper embedded steel plate 30-1, and install lower connecting bolts between the lower flange of the new support and the lower embedded steel plate 1-1.

[0138] Step 7: Operate the self-propelled electric hydraulic lifting platform to rotate the disassembly and assembly device 180° so that the disassembly and assembly cylinder 26 is positioned close to another support 19 to be disassembled. Repeat steps 1 to 6 to disassemble the other support 19 to be disassembled on the right end and install the new support.

[0139] In this embodiment, step 403 involves operating the locking mechanism to release the locking of the right guide rod 23. The specific process is as follows:

[0140] The rotation of the operating handle 12-6 drives the gear 12-4 to rotate via the shaft 12-7. The rotation of the gear 12-4 drives the positioning pin 12-1 to move away from the right guide rod 23 via the rack 12-11, so that the first tooth of the positioning pin 12-1 and the second tooth of the right guide rod 23 are moved away from each other.

[0141] The specific process of locking the right guide rod 23 by operating the locking mechanism in step 405 is as follows:

[0142] The rotation of the operating handle 12-6 drives the gear 12-4 to rotate in the opposite direction via the shaft 12-7. The reverse rotation of the gear 12-4 drives the positioning pin 12-1 to engage with the right guide rod 23 via the rack 12-11, so that the first tooth of the positioning pin 12-1 and the second tooth of the right guide rod 23 are engaged.

[0143] In this embodiment, when the piston rod 29 of the disassembly and assembly cylinder extends through the disassembly and assembly connecting seat 8 and the left end disassembly and assembly head 7 to push the support 4 to be disassembled in step 501, the left guide rod 10 connected to the left end disassembly and assembly head 7 slides and guides along the left guide sleeve 27-1.

[0144] In step 403, when the piston rod 18 of the adjusting cylinder extends and drives the right end disassembly head 20 to move through the adjusting cylinder connecting seat 21, the right guide rod 23 connected to the right end disassembly head 20 slides and is guided along the right guide sleeve 24 and the middle guide sleeve 16.

[0145] In this embodiment, the upper liner 6-1 and the lower liner 6-2 are installed in actual use to reduce the pressure on the upper structure and the lower structure.

[0146] In this embodiment, during actual use, kerosene is sprayed onto the contact surface around the upper flange 4-1 and the upper embedded steel plate 30-1, as well as onto the connecting bolts 3 between the upper flange 4-1 and the upper embedded steel plate 30-1; and kerosene is also sprayed onto the contact surface around the lower flange 4-2 and the lower embedded steel plate 1-1, as well as onto the connecting bolts 3 between the lower flange 4-2 and the lower embedded steel plate 1-1. Utilizing the strong penetrability of kerosene, the corrosion that may have occurred in these two areas due to decades of contact is resolved, thereby reducing the resistance to disassembling the support and bolts.

[0147] In this embodiment, in actual use, threaded connection holes 7-5 are provided in the upper disassembly and assembly connecting plate 7-2 and the lower disassembly and assembly connecting plate 7-1. This is so that the upper connecting bolt and the lower connecting bolt can be connected after passing through the threaded connection hole 7-5 and the mounting holes of the upper flange 4-1 and the lower flange 4-2, and the connecting bolts will not fall off.

[0148] In summary, the present invention is reasonably designed and easy to construct, effectively solving the problem of rapid, safe and convenient disassembly and assembly of seismic isolation rubber bearings that are arranged in rows symmetrically in the seismic isolation layer of seismic isolation buildings and have lost their load-bearing function.
