Description

Technical Field

[0001] The present invention belongs to the technical field of bearing replacement devices, and more specifically, relates to a high-precision replacement system and method for rubber seismic isolation bearings in a seismic isolation layer of a building construction project. Background Art

[0002] With the development of society, the scope of the construction industry is becoming wider and wider, and various buildings (structures) are spread all over the place. When a building (structure) is located in an earthquake zone, in order to protect the safety of users, various shock-absorbing and seismic isolation measures will be taken to reduce the destructive effects of an earthquake on the building (structure). Rubber seismic isolation bearings are one of them. However, since the rubber material itself has a certain lifespan, the rubber isolation bearings cannot reach the design service life of the building and need to be replaced. Moreover, when the building is affected by an earthquake, the effectiveness of the rubber isolation bearings will also be affected and they also need to be replaced. At present, most rubber isolation bearings in building construction projects are installed in the isolation layer. The isolation layer is a cavity under the bottom plate of the first floor of the building. The isolation layer is separated from the outside world by a concrete retaining wall. Therefore, a device that is easy to replace rubber isolation bearings and can operate efficiently is designed.

[0003] In order to solve the above technical problems, Chinese invention patent CN112681796A discloses a method for installing and replacing seismic isolation rubber bearings on cast-in-place piles, including: A. Construction of cast-in-place piles below the ground, binding of steel bars and layout of formwork above the ground; B. Installation and fixation of auxiliary tooling, pouring of pile body concrete above the ground; C. Removal of auxiliary tooling; D. Installation and fixation of positioning plates and connecting parts of the seismic isolation bearing; E. Grouting and anchoring of connecting parts; F. Installation of steel pads; G. Installation of seismic isolation bearings; H. Construction of the superstructure. The replacement of the seismic isolation bearing includes: I. Expansion and reinforcement of the pile foundation, replacement of the operating platform; J. Preparation for jacking work and arrangement of jacking equipment; K. Formal jacking; L. Removal of the seismic isolation bearing to be replaced and removal of the steel pad; M. Installation of the steel pad and installation of the new seismic isolation bearing; N. Unloading of the jack and tightening of the connecting bolts; In addition, Chinese invention patent CN111648254B ​​discloses a method for rapid installation and replacement of a bridge seismic isolation rubber bearing, which has the same structure as the upper and lower embedded steel plates installed in conjunction with the bearing body, with an anchor connected to its back and a groove on its inner side, connected to the bearing. The upper and lower structural convex plates on the end face of the core body are provided with convex blocks that fit into the gap of the groove; its installation and replacement methods include: S1 support modification: opening a prying point and a hook for connecting to facilitate dragging out on the side end face of the structural convex plate under the support; S2 installation method: laying out the line at the pad stone position, tying the steel cage, pre-embedding the lower embedded steel plate, and pouring the pad stone concrete; pre-embedding the upper embedded steel plate at the bottom of the beam body; hoisting the support body and hoisting the beam body; S3 replacement method: jacking up the beam body, prying the support body out of the lower embedded steel plate groove and dragging it out; dragging in the new support body; confirming the position and slowly lowering the beam to complete the replacement.

[0004] The above patented technologies all achieve the technical effect of facilitating the replacement of rubber seismic isolation bearings by improving the bearing body or pier, but the following technical problems still exist: (1) In actual engineering, the upper pier of the seismic isolation is usually basically in contact with the upper flange plate of the rubber seismic isolation bearing, so there is no corresponding lifting surface of the jack, so the jack cannot be used for disassembly and assembly in most occasions; (2) Since a single rubber seismic isolation bearing weighs nearly one ton, it is difficult to move it manually or with a hand winch, which makes it difficult to replace the rubber seismic isolation bearing, requires a lot of physical strength from the workers, and reduces the construction efficiency; (3) The inspection hole for people to enter and inspect is generally set on the retaining wall or the bottom plate of the first floor. The size of the inspection hole is limited and cannot accommodate large machinery to assist in installation and disassembly. Summary of the Invention

[0025] According to a second aspect of the present invention, a high-precision replacement method for a rubber isolation bearing in a seismic isolation layer of a building construction project is provided, which is implemented using a high-precision replacement system for a rubber isolation bearing in a seismic isolation layer of a building construction project, comprising:

[0026] S100: The operating personnel enter the isolation layer to inspect the rubber isolation bearings, accurately count the specifications, dimensions, models, and quantities of the rubber isolation bearings that need to be replaced, and process them into new rubber isolation bearings according to the statistical data and transport them to the site;

[0027] S200: The components of the support unit and the disassembly and assembly auxiliary unit are moved from the manhole to the isolation layer manually or by external machinery, and the device is assembled inside the isolation layer;

[0028] S300: Calculate the load on the rubber isolation bearing to be replaced, select a sufficient number of support units, and ensure that the load that the support unit can withstand is at least 1 / 2 times the actual load of the rubber isolation bearing to be replaced. Determine the appropriate support position on the isolation coupling beam, mark the corresponding position on the isolation layer ground, push the support unit to move it to the marked position, and maintain the support unit position unchanged;

[0029] S400: Use an electric wrench or adjustable wrench to remove the bolts fixing the upper and lower flanges of the rubber isolation support. Push the disassembly and assembly auxiliary unit and move it to the side of the lower isolation pier using the second universal wheel.

[0030] S500: Pass the binding rope on the winch horizontally through the rubber isolation bearing to form a closed loop. Start the winch, retract the binding rope, and slowly move the rubber isolation bearing toward the winch. When the lower flange plate of the rubber isolation bearing is completely seated on the bearing support, pull the disassembly and assembly auxiliary unit to the inspection hole under the action of the second universal wheel. Use an external machine to move the replaced rubber isolation bearing out of the isolation layer.

[0031] S600: Place the new rubber isolation bearing on the bearing support part of the disassembly and assembly auxiliary unit through external machinery, push the disassembly and assembly auxiliary unit again, and move it to one side of the lower isolation pier under the action of the second universal wheel. Fix a disassembly and assembly auxiliary unit on the opposite side of the lower isolation pier. Pass the binding rope of the opposite disassembly and assembly auxiliary unit horizontally through the rubber isolation bearing, start the winch of the opposite disassembly and assembly auxiliary unit, and drive the rubber isolation bearing to move slowly toward the lower isolation pier until the flange below the rubber isolation bearing is stably seated on the lower isolation pier, and the bolt holes of the upper and lower flanges of the rubber isolation bearing are aligned with the bolt holes of the upper and lower isolation piers respectively. After positioning with screws to ensure installation is completed, loosen the disassembly and assembly auxiliary unit and the support unit, and repeat the above steps to replace the next rubber isolation bearing.

[0032] Furthermore, step S300 includes: controlling the jack to extend by adjusting the control knob, and since the first universal wheel under the support column is elastically connected by a spring, the first universal wheel is retracted toward the inside of the support column, thereby causing the support column to move downward relative to the vibration transmission rod until the lower end of the support column is completely in contact with the ground, thereby achieving stable support and transmission of the upper load by the support column.

[0033] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0034] 1. The equipment of the present invention prevents structural deformation during the disassembly and assembly of the rubber isolation bearings by setting support devices under the isolation connecting beams on both sides corresponding to the rubber isolation bearings to be removed. In addition, the horizontal dragging method is provided to effectively solve the technical problem that in actual engineering, the upper isolation pier and the upper flange plate of the rubber isolation bearing are basically in contact with each other, resulting in no corresponding lifting surface for the jack, making it impossible to use the jack for disassembly and assembly in most situations.

[0035] 2. The equipment of the present invention is provided with a winch above the disassembly and assembly auxiliary unit, which can pull out the rubber seismic isolation bearing directly without manual pulling, effectively solving the technical problem that the rubber seismic isolation bearing is difficult to disassemble manually due to its heavy weight, greatly reducing the labor force of the workers, thereby saving the workers' physical strength and improving the work efficiency of replacement.

[0036] 3. In the equipment of the present invention, the support unit and the disassembly and assembly auxiliary unit are relatively small in size and are of a detachable structure. When in use, the assembled components can be moved one by one from the inspection hole of the isolation layer to the inside of the isolation layer, thereby completing the installation of the equipment inside the isolation layer, solving the technical problem that large equipment cannot be transported into the isolation layer due to the small size of the inspection hole.

[0037] 4. The equipment of the present invention calculates the load of the rubber isolation bearing to be replaced, selects a sufficient number of support units, and assembles and connects multiple support units through expansion holes and connecting pins, so that a matching number of installations can be carried out according to different stress environments, effectively avoiding the technical problem of difficulty in placing support equipment due to limited space.

[0038] 5. The device of the present invention controls the jack to extend by adjusting the control knob. Since the first universal wheel under the support column is elastically connected by a spring, the first universal wheel is retracted toward the inside of the support column, and then the support column moves downward relative to the vibration transmission rod until the lower end of the support column is completely in contact with the ground, thereby achieving stable support and transmission of the upper load by the support column, and ensuring that the lower part is no longer connected through a pulley, avoiding the posture movement problem caused by the rolling connection.

DETAILED DESCRIPTION

[0048] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to illustrate the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0049] like Figures 1 to 5 As shown, in an embodiment of the present invention, a high-precision replacement system for rubber isolation bearings in the isolation layer of a building construction project is provided, comprising:

[0050] The vibration isolation unit 1 includes a vibration isolation connecting beam 101 connected to the upper isolation buttress 103 at both ends and having the function of transmitting and dispersing vibrations, a vibration isolation lower buttress 102 fixed to the ground, and a rubber vibration isolation bearing 4 connected to the vibration isolation connecting beam 101 and the lower isolation buttress 102 via a flange and screws between the two to buffer vibrations and indirectly transmit them to the ground.

[0051] Support unit 2 for supporting the vibration isolation connecting beam 101 to maintain the original position;

[0052] The disassembly and assembly auxiliary unit 3 is used to assist in the disassembly and installation of the rubber seismic isolation bearing 4, which is installed in pairs and relatively on both sides of the lower isolation pier 102 below the rubber seismic isolation bearing 4 to be replaced. The disassembly and assembly auxiliary unit 3 includes a working platform 310 provided with a winch installation part 311 for fixing the winch 314 and a bearing support part 312 for supporting and temporarily placing the rubber seismic isolation bearing 4, a supporting leg 301 fixedly connected to the bottom of the working platform 310 through a threaded connection end 303 and provided with a second universal wheel 302 at the lower end to facilitate the movement of the platform, and a binding rope 315 extending from the winch 314.

[0053] In an embodiment of the present invention, a support device is provided below the isolation connecting beams on both sides of the rubber isolation bearing to be removed, thereby preventing structural deformation during the disassembly and assembly of the rubber isolation bearing. In addition, a horizontal dragging method is provided, which effectively solves the technical problem that in actual engineering, the upper isolation pier and the upper flange plate of the rubber isolation bearing are basically in contact with each other, thereby lacking a corresponding lifting surface for the jack and making it impossible to use the jack for disassembly and assembly in most cases. A winch is provided above the disassembly and assembly auxiliary unit, so that the rubber isolation bearing can be pulled out without manual pulling, effectively solving the technical problem that the rubber isolation bearing is difficult to disassemble manually due to its heavy weight, greatly reducing the labor of workers, thereby saving workers' physical strength and improving the efficiency of replacement. In addition, the support unit and the disassembly and assembly auxiliary unit are small in size and are detachable structures. When in use, the assembled components can be moved one by one from the inspection hole of the isolation layer to the isolation layer, thereby completing the installation of the equipment inside the isolation layer, solving the technical problem that large equipment cannot be transported into the isolation layer due to the small size of the inspection hole.

[0054] like Figure 6 、 Figure 7 As shown, in this embodiment of the present invention, the support unit 2 includes:

[0055] A first universal wheel 202 that can be extended vertically and elastically connected to the bottom of the support column 201;

[0056] The jack 208 with adjustable length is extended by controlling the knob 203, with its lower end fixedly connected to the upper part of the support column 201 and its upper end detachably connected to the vibration transmission rod 204;

[0057] A rotation expansion hole 206 and a connecting pin 207 are fixedly arranged at one end of the vibration transmission rod 204 and used to expand and connect multiple vibration transmission rods 204.

[0058] In an embodiment of the present invention, by performing load calculations on the rubber isolation bearings to be replaced, a sufficient number of support units are selected, and multiple support units are assembled and connected through the expansion hole 206 and the connecting pin 207, so that a matching number of installations can be carried out according to different stress environments, effectively avoiding the technical problem of difficulty in placing support equipment due to limited space, and at the same time achieving 360-degree rotation, thereby increasing the scope of application of the device.

[0059] During use, the jack 208 is controlled to extend by adjusting the control knob 203. Since the first universal wheel 202 under the support column 201 is elastically connected by a spring, the first universal wheel 202 is retracted toward the inside of the support column 201, and the support column 201 moves downward relative to the vibration transmission rod 204 until the lower end of the support column 201 is completely in contact with the ground, thereby achieving stable support and transmission of the upper load by the support column 201, and ensuring that the lower part is no longer connected by a pulley, avoiding the posture movement problem caused by the rolling connection.

[0060] like Figure 5 As shown, in this embodiment of the present invention, the disassembly and assembly auxiliary unit 3 includes:

[0061] A plurality of rotating rollers 313 evenly arranged and rotatably connected to the support portion 312 for changing the sliding between the rubber isolation support 4 and the support portion 312 into rolling;

[0062] The clamping positioning unit 320 is clamped by a first clamping end 316 provided at the front end of the support portion 312 and a second clamping end 322 provided on one side of the transition rod 321. It includes a transition rod 321 and a clamping head 323 connected to the top of the transition rod 321 through a positioning pin 325. The positioning pin 325 is positioned by simultaneously passing through a first mounting hole 324 provided at the rear end of the clamping head 323 and a second mounting hole 326 provided in the transition rod 321.

[0063] In an embodiment of the present invention, by setting a rolling connection method, the movement efficiency of the rubber isolation bearing on the working platform 310 is improved, and the execution power of the disassembly and assembly auxiliary unit is effectively reduced. At the same time, by setting a clamping positioning mechanism, the lower isolation pier is positioned, thereby avoiding the free movement of the disassembly and assembly auxiliary unit.

[0064] During use, after the disassembly and assembly auxiliary unit is moved to the side of the vibration isolation lower pier, the transition rod is first clamped to the front end of the working platform, and the clamping head is positioned on the transition rod with a positioning pin according to the size of the vibration isolation lower pier, thereby playing a clamping and positioning role.

[0065] like Figure 8As shown, in an embodiment of the present invention, a method for using a high-precision replacement system for rubber isolation bearings in a building construction isolation layer includes the following steps:

[0066] Step 1: The operator enters the isolation layer to inspect the rubber isolation bearings, accurately counts the specifications, dimensions, models, and quantities of the rubber isolation bearings that need to be replaced, and processes them into new rubber isolation bearings according to the statistical data and transports them to the site;

[0067] Step 2: Move the components of the support unit and the disassembly and assembly auxiliary unit from the inspection hole to the isolation layer manually or by external machinery, and complete the assembly of the device inside the isolation layer;

[0068] Step 3: Calculate the load on the rubber isolation bearings to be replaced and select a sufficient number of support units to ensure they can withstand a load at least 1.5 times the actual load on the rubber isolation bearings to be replaced. Determine the appropriate support position on the isolation coupling beam, mark the corresponding position on the isolation layer floor, and move the support unit to the marked position, maintaining the support unit in place.

[0069] Step 4: Use an electric wrench or an adjustable wrench to remove the fixing bolts of the upper and lower flanges of the rubber isolation support, push the disassembly and assembly auxiliary unit, and move it to one side of the isolation lower pier under the action of the second universal wheel 302;

[0070] Step 5: Pass the binding rope on the winch horizontally through the rubber isolation bearing to form a closed loop. Start the winch, retract the binding rope, and slowly move the rubber isolation bearing toward the winch. When the lower flange plate of the rubber isolation bearing is completely seated on the bearing support, pull the disassembly and assembly auxiliary unit and, using the second universal wheel, move it to the inspection hole. Use an external mechanism to remove the replaced rubber isolation bearing from the isolation layer.

[0071] Step 6: Place the new rubber seismic isolation bearing on the bearing support part of the disassembly and assembly auxiliary unit through external machinery, push the disassembly and assembly auxiliary unit again, and move it to one side of the seismic isolation lower pier under the action of the second universal wheel, and fix a disassembly and assembly auxiliary unit on the opposite side of the seismic isolation lower pier. Pass the binding rope of the opposite disassembly and assembly auxiliary unit horizontally through the rubber seismic isolation bearing, start the winch of the opposite disassembly and assembly auxiliary unit, and drive the rubber seismic isolation bearing to move slowly toward the seismic isolation lower pier until the flange below the rubber seismic isolation bearing is stably seated on the seismic isolation lower pier, and the bolt holes of the upper flange and lower flange of the rubber seismic isolation bearing are aligned with the bolt holes of the upper and lower seismic isolation piers respectively. Finally, position it with screws to ensure that the installation is completed, loosen the disassembly and assembly auxiliary unit and the support unit, and repeat the above steps to replace the next rubber seismic isolation bearing.

[0072] The step 3 includes: controlling the jack 208 to extend by adjusting the control knob 203. Since the first universal wheel 202 below the support column 201 is elastically connected by a spring, the first universal wheel 202 is retracted toward the inside of the support column 201, thereby causing the support column 201 to move downward relative to the vibration transmission rod 204 until the lower end of the support column 201 is completely in contact with the ground, thereby achieving stable support and transmission of the upper load by the support column 201, and ensuring that the lower part is no longer connected by a pulley, avoiding the posture movement problem caused by the rolling connection.

[0073] The step 5 includes: after the disassembly and assembly auxiliary unit is moved to one side of the vibration isolation lower pier, the transition rod is first clamped to the front end of the working platform, and the clamping head is positioned on the transition rod with a positioning pin according to the size of the vibration isolation lower pier, thereby playing a clamping and positioning role.

[0074] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
