Description

Technical Field

[0001] The present invention relates to the technical field of building earthquake resistance, and in particular to a seismic isolation and tensile resistance device that works throughout an earthquake process. Background Art

[0002] Isolation bearings are key components in building seismic resistance. Through their elastic deformation and energy dissipation mechanisms, they cushion the ground's violent vibrations during earthquakes, reducing the building's sway and thus protecting the building's main structure and internal facilities, thereby minimizing damage. While isolation bearings excel in resisting vertical and horizontal earthquake forces, their tensile strength is relatively weak. Under strong earthquakes, especially when vertical forces or complex seismic waves are present, isolation bearings may experience excessive tensile stresses. Once the tensile stress exceeds their limit, the bearings are susceptible to failure, compromising the overall building's seismic isolation performance. Currently, to address the issue of isolation bearings' poor tensile strength, existing isolation systems utilize tensile devices to dissipate the tensile forces acting on the bearings. Tensile viscous dampers are one of the most effective tensile devices for building seismic resistance. These dampers utilize the damping properties of the viscous medium on either side of the piston to dissipate seismic energy as the piston rod extends and retracts, actively dissipating the tensile stress on the isolation bearings and significantly reducing the tensile forces acting on them.

[0003] However, the existing seismic isolation and tensile devices, which use isolation bearings and tensile viscous dampers as their main components, lack a design that can record the expansion and contraction data of the tensile viscous dampers. This makes it difficult for relevant personnel to know the maximum extension and retraction amplitude of the tensile viscous dampers during earthquakes, and it is impossible to grasp their working range and response level, which is not conducive to the subsequent optimization of the performance of the seismic isolation and tensile devices.

DETAILED DESCRIPTION

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0038] First embodiment:

[0039] Please refer to Figures 1-8In a first embodiment of the present invention, the seismic isolation and anti-tension device that works throughout the entire earthquake process includes: a seismic isolation support 3 fixedly installed between the upper pier 1 and the lower pier 2. The seismic isolation support 3 can be a natural rubber support, a lead rubber support, an elastic slide support, a three-dimensional seismic isolation support, etc. commonly used in the prior art. A flip pier is provided on the top of the lower pier 2, and the bottom of the seismic isolation support 3 is fixedly installed on the top of the flip pier. The seismic isolation and anti-tension device that works throughout the entire earthquake process also includes a plurality of tensile viscous dampers 4. The plurality of tensile viscous dampers 4 are evenly distributed around the seismic isolation support 3. Both ends of the plurality of tensile viscous dampers 4 are respectively connected to the upper pier 1 and the lower pier 2 through a universal hinge 5. One end of the universal hinge 5 is fixedly connected to the tensile viscous damper 4, and the other end is rotatably connected to the mounting plate , the two mounting plates are fixedly connected to the upper pier 1 and the lower pier 2 respectively, the tensile viscous damper 4 plays a role in the whole process of earthquake, sharing the tensile stress of the seismic isolation support 3 while dissipating the seismic energy through the hysteresis energy dissipation of the tensile viscous damper 4, and the tensile viscous damper 4 and the seismic isolation support 3 are structurally decoupled from each other, a C-shaped plate 7 is provided on one side of the tensile viscous damper 4, four fixed arms 6 are fixedly installed on the C-shaped plate 7, and the ends of the four fixed arms 6 away from the C-shaped plate 7 are connected to the cylinder body of the tensile viscous damper 4, two scale plates 8 are slidably installed in the C-shaped plate 7, and the two scale plates 8 are symmetrically arranged, and a push rod 9 is installed on the piston rod of the tensile viscous damper 4, and the push rod 9 extends to the two scale plates away from the end of the tensile viscous damper 4 The plates 8 are located between the two plates, and are in contact with the inner wall of the C-shaped plate 7 relative to the tensile viscous damper 4. During the up and down movement of the push rod 9, the two scale plates 8 can be pushed to move outward of the C-shaped plate 7 respectively. A plurality of card slots 801 are provided at equal intervals on the outer wall of the scale plate 8 away from the tensile viscous damper 4. Two fixing frames 10 are fixedly installed on the outer wall of the C-shaped plate 7 away from the tensile viscous damper 4. The two fixing frames 10 are respectively located at the two end positions of the C-shaped plate 7. A first smooth rod 11 is penetrated and slidably installed on the two fixing frames 10. The two first smooth rods 11 are fixedly installed with a clamping head 14 on one end close to the scale plate 8. The two clamping heads 14 extend into the corresponding card slots 801 on one end close to the tensile viscous damper 4, and are provided with arcs. The first spring 13 is provided on the first smooth rod 11, and one end of the first spring 13 is fixedly connected to the fixing frame 10, and the other end is fixedly connected to the operating plate 12. In the process of pushing the scale plate 8 to move, the push rod 9 exerts a thrust on the arc sliding surface 141 through the scale plate 8, causing the clamping head 14 to move away from the tensile viscous damper 4 and finally exit the previous slot 801. In this process, the first spring 13 will be stretched. As the scale plate 8 moves, when the next slot 801 is axially aligned with the clamping head 14, due to the loss of obstruction, under the tension of the first spring 13,The clamping head 14 will be reset and re-engaged into the clamping slot 801 aligned with it.

[0040] In this embodiment, in order to increase the reliability of the restriction on the scale plate 8, a rubber pad 15 is fixedly installed on the inner wall of the slot 801 on one side relative to the fixing frame 10, and the end of the clamping head 14 away from the first smooth rod 11 is in conflict with the corresponding rubber pad 15. Under the pulling force of the first spring 13, the clamping head 14 and the rubber pad 15 are in a tight state, which can prevent the scale plate 8 from moving at will.

[0041] In this embodiment, in order to limit the installation position of the scale plate 8, two installation positioning blocks are fixedly installed on the inner wall of one side of the C-shaped plate 7 relative to the tensile viscous damper 4 and at the middle position. The ends of the two scale plates 8 close to each other are in contact with the two installation positioning blocks, and the two installation positioning blocks are respectively located on both sides of the push rod 9. When the scale plate 8 is inserted into the C-shaped plate 7, when the scale plate 8 conflicts with the installation positioning block, it proves that the installation is in place. At this time, the end of the scale plate 8 away from the installation positioning block is flush with the corresponding end of the C-shaped plate 7.

[0042] In this embodiment:

[0043] During an earthquake, the seismic isolation support 3 acts as a seismic isolation, reducing the transmission of seismic energy to the upper structure. The tensile viscous damper 4 works due to the relative movement of the upper buttress 1 and the lower buttress 2. During the extension and retraction of its piston rod, the damping effect of the viscous medium on both sides of the piston dissipates energy, thereby sharing the tension and pressure on the seismic isolation support 3, reducing the tension on the seismic isolation support 3 accordingly, thereby preventing the seismic isolation support 3 from being damaged or affecting its seismic isolation performance due to excessive tension.

[0044] When the cam 8 is in the process of being moved upward, the cam 8 is pressed against the upper end of the cam 8 and the cam 8 is in the process of being moved downward.

[0045] When the push rod 9 stops pushing, the scale plate 8 no longer moves. After the push rod 9 is reset with the piston rod, the scale plate 8 is blocked by the clamp 14 and cannot be reset. The length of the part of the scale plate 8 moved outside the C-shaped plate 7 is roughly the length of the piston rod extended or retracted this time. If the subsequent earthquake intensity intensifies and the piston rod of the tension viscous damper 4 is extended and retracted to a greater extent, the push rod 9 will move a greater distance than the last time, thereby further pushing the scale plate 8 outward. On the contrary, if the subsequent earthquake intensity weakens, the movement distance of the push rod 9 will be relatively small and it will no longer be able to reach the scale plate 8. In this way, after the earthquake, after measuring the length of the parts of the two scale plates 8 outside the C-shaped plate 7, the maximum amplitude of the extension and retraction of the piston rod of the tension viscous damper 4 in this earthquake can be obtained, thereby knowing the working range and response degree of the viscous damper during the earthquake, and providing a basis for the subsequent structural design and optimization of the tension viscous damper 4;

[0046] After the scale plate 8 is moved outward to the desired length, the handheld operating panel 12 is pulled away from the C-shaped plate 7 to allow the clamping head 14 to exit the clamping slot 801, thereby releasing the restriction on the scale plate 8. The scale plate 8 can then be fully pushed into the C-shaped plate 7. After the scale plate 8 is pushed into place, the operating panel 12 is released and the clamping head 14 is used again to restrict the scale plate 8.

[0047] Compared with related technologies, the seismic isolation and tensile device provided by the present invention, which works throughout the entire earthquake process, has the following beneficial effects:

[0048] By arranging a plurality of tensile viscous dampers 4 around the seismic isolation support 3, the tensile viscous dampers 4 are respectively connected to the upper pier 1 and the lower pier 2 through the universal hinge 5, which can share the tensile stress of the seismic isolation support 3 during the earthquake, so that the tensile force borne by the seismic isolation support 3 is reduced accordingly, which can effectively avoid the seismic isolation support 3 from being damaged or affecting its seismic isolation performance due to excessive tensile force; by installing a push rod 9 on the piston rod of the tensile viscous damper 4, arranging a C-shaped plate 7 with a fixed arm 6 on one side of the tensile viscous damper 4, and slidingly installing two scale plates 8 in the C-shaped plate 7, combined with the fixed The arrangement of the fixed frame 10, the first smooth rod 11, the clamping head 14, the operating panel 12, the first spring 13 and other components, when the piston rod of the tensile viscous damper 4 is extending and retracting during the earthquake, can correspondingly drive the push rod 9 to push the two scale plates 8 to move outward from the C-shaped plate 7, and the position of the scale plate 8 can be locked and will not be reset with the reset of the push rod 9, so that relevant personnel can measure the maximum extension and retraction amplitude of the piston rod of the tensile viscous damper 4 during the earthquake after the earthquake, thereby knowing its working range and response degree, and providing a basis for the subsequent structural design and optimization of the tensile viscous damper 4.

[0049] Second embodiment:

[0050] Based on the seismic isolation and tensile device provided by the first embodiment of the present application, which operates throughout the entire earthquake process, the second embodiment of the present application proposes another seismic isolation and tensile device that operates throughout the entire earthquake process. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0051] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and implementation plans.

[0052] Please refer to Figures 9-11 In the seismic isolation and tensile device that works throughout the earthquake process provided by this embodiment, four first plug-in blocks 16 are fixedly installed on the cylinder body of the tensile viscous damper 4, and a round plug hole 1601 is opened on each of the four first plug-in blocks 16. The round plug hole 1601 is adapted to the fixed arm 6, and the four fixed arms 6 extend into the corresponding first plug-in blocks 16 at one end away from the C-shaped plate 7. A second plug-in block 17 is fixedly installed on the piston rod of the tensile viscous damper 4, and the second plug-in block 17 is adapted to the push rod 9. The push rod 9 extends into the second plug-in block 17 at one end away from the C-shaped plate 7. A second smooth rod 18 is passed through and slidably installed on each of the four fixed arms 6. Two bow-shaped operating strips 19 are provided between the four fixed arms 6. The two bow-shaped operating strips 19 are staggered, and one of the bow-shaped operating strips 19 has a Sliding mouth, another bow-shaped operating strip 19 is located in the sliding mouth and is slidably connected to the inner wall of the sliding mouth. The two ends of the bow-shaped operating strip 19 are respectively fixedly connected to the corresponding two second smooth rods 18, and the second smooth rod 18 is fixedly installed with a first end plate 20 at one end away from the corresponding bow operating strip 19. Both ends of the two bow operating strips 19 are also fixedly installed with latches 22. The four latches 22 all pass through the corresponding round sockets 1601 and are slidably connected to the corresponding round sockets 1601. A limiting circular hole is opened on the fixed arm 6. The four latches 22 respectively pass through the corresponding limiting circular holes and are slidably connected to the inner wall of the corresponding limiting circular hole. A second spring 21 is sleeved on the second smooth rod 18, and one end of the second spring 21 is fixedly connected to the first end plate 20, and the other end is fixedly connected to the fixed arm 6.

[0053] In this embodiment, the same fixing rod 23 is fixedly installed between the two fixing arms 6 located at the bottom, and a round blocking rod 24 is fixedly installed on the top of the fixing rod 23. The two bow-shaped operating strips 19 are pinched with the index finger and thumb so that the two bow-shaped operating strips 19 are close to the fixing rod 23. During the movement of the bow-shaped operating strip 19, the corresponding two pins 22 are driven to move. When the bow-shaped operating strip 19 contacts the round blocking rod 24, the four pins 22 will all withdraw from the corresponding round sockets 1601.

[0054] In this embodiment, in order to improve the comfort of operation, operating ears are fixedly installed on the two arched operating bars 19. The operating ears are made of silicone material and have a gripping arc groove.

[0055] In this embodiment, in order to allow the latch 22 to be inserted into the round insertion hole 1601 more smoothly, the connection between the end surface of the latch 22 away from the corresponding bow-shaped operating strip 19 and the outer peripheral wall is rounded.

[0056] In this embodiment:

[0057] With the above arrangement, when the C-shaped plate 7, push rod 9 and other components are not initially installed on the tensile viscous damper 4, since the tensile viscous damper 4 and the C-shaped plate 7 are designed to be quickly detachable and installable, the C-shaped plate 7, push rod 9 and other components can be quickly installed on the tensile viscous damper 4 at any time, so that the manufacturer can obtain the maximum extension and contraction amplitude of the piston rod of the tensile viscous damper 4 during the epicenter.

[0058] When installing the C-shaped plate 7 and the push rod 9, first insert the upper end of the push rod 9 into the second plug-in block 17, and then pinch the two bow-shaped operating strips 19 with the index finger and thumb respectively, and make the two bow-shaped operating strips 19 contact the round blocking rod 24. In this process, the two bow-shaped operating strips 19 will drive the corresponding latch 22 and the second smooth rod 18 to move outward, and the four second springs 21 will be compressed to store elastic potential energy, and the four latches 22 will eventually separate from the corresponding fixed arms 6. Then, the four fixed arms 6 are respectively aligned with the four first plug-in blocks 16 and pushed in. In this process, the bottom end of the push rod 9 will enter between the two scale plates 8. When the four fixed arms 6 are inserted into place , the bottom end of the push rod 9 will contact the inner wall of the side of the C-shaped plate 7 relative to the tensile viscous damper 4, and the four latches 22 will be axially aligned with the corresponding circular sockets 1601. Then, after the two bow-shaped operating strips 19 are released, under the elastic force of the four second springs 21, the two bow-shaped operating strips 19 will perform a reset movement, driving the latch 22 to be inserted into the circular socket 1601. In the process of passing through the circular socket 1601, the latch 22 will pass through the limiting circular hole on the fixed arm 6, so that the fixed arm 6 is reliably restricted in the first plug-in block 16, realizing the reliable installation of the C-shaped plate 7. When the C-shaped plate 7 is reliably installed, the push rod 9 is also reliably restricted and will not slip out of the second plug-in block 17;

[0059] This embodiment realizes the quick and detachable installation function of components such as the C-shaped plate 7 and the push rod 9 and the anti-tensile viscous damper 4 by arranging four first plug-in blocks 16 with round sockets 1601 on the cylinder body of the anti-tensile viscous damper 4, arranging a second plug-in block 17 on the piston rod, and arranging a second smooth rod 18, a second spring 21, a bow-shaped operating strip 19, a pin 22 and other components on the fixed arm 6. It has the advantages of convenient and efficient installation and disassembly, stable and reliable structural connection, and convenience for the later installation of detection components to obtain the epicenter expansion and contraction data of the piston rod, effectively improving the flexibility and practicality of the seismic isolation and anti-tensile device working throughout the earthquake process.

The end of the marking rod 29 away from the marking carrier 26 extends into the limiting ring 32, and the fixed slide 30 is away from the fixed plate 2 The second end plate 33 is fixedly mounted on one end of 7, and a third spring 34 is sleeved on the fixed slide rod 30. One end of the third spring 34 is fixedly connected to the second end plate 33, and the other end is fixedly connected to the fixed plate 27. The top and bottom of the horizontal section of the push rod 9 are both provided with breaking notches 901. When the scale plate 8 is mechanically stuck and cannot move, the part of the push rod 9 located inside the C-shaped plate 7 will break through the two breaking notches 901. In this way, the remaining part of the push rod 9 can continue to follow the movement of the piston rod of the tensile viscous damper 4, thereby driving the marking rod 29 to move accordingly. During the movement of the marking rod 29, friction occurs with the marking carrier plate 26, thereby Graphite marks are left on the recording plate 26. After the push rod 9 breaks, the limiting round rod still conflicts with the C-shaped plate 7, and thus the push rod 9 can still be restricted from slipping out of the second plug-in block 17. The initial height of the marking rod 29 is located at the center point of the marking carrier plate 26. Subsequently, by measuring the length values ​​of the graphite marks on both sides of the center point on the marking carrier plate 26, the maximum amplitude of the extension and retraction of the piston rod of the tensile viscous damper 4 can be obtained. When the scale plate 8 is operating normally, the result measured by the displacement of the scale plate 8 can be mutually verified with the result recorded by the graphite marks on the marking carrier plate 26, thereby improving the reliability of the measurement data.

[0064] In this embodiment, in order to facilitate the installation of the marking carrier 26, the same first magnet piece is fixedly installed in the two fixing frames 25, and a second magnet piece is fixedly installed on the outer wall of the marking carrier 26 close to the C-shaped plate 7, and the two magnet pieces are attracted to each other.

[0065] In this embodiment, in order to facilitate the operation of the pressing plate 31 , an L-shaped operating handle is fixedly mounted on the outer wall of the pressing plate 31 away from the limiting ring 32 .

[0066] In this embodiment:

[0067] When installing the marking carrier 26, the marking carrier 26 is placed between the two fixing frames 25. The first magnet sheet and the second magnet sheet will attract each other to fix the marking carrier 26. When installing the marking rod 29, the pressure plate 31 is first pulled toward the direction of the tensile viscous damper 4 through the L-shaped operating handle. During this process, the third spring 34 will be compressed, and then the pressure plate 31 is rotated downward to stagger with the cylinder 28. Then, the marking rod 29 is inserted into the cylinder 28 and The front end of the pressing plate 31 is brought into contact with the marking carrier plate 26, and the pressing plate 31 is then rotated upward until the limiting ring 32 is aligned with the axis of the cylinder 28. Finally, the L-shaped operating handle is released. Under the elastic force of the third spring 34, the pressing plate 31 approaches the marking rod 29, and the limiting ring 32 on the pressing plate 31 is sleeved on the marking rod 29. Under the pressure of the pressing plate 31, the marking rod 29 is tightly attached to the marking carrier plate 26, and the marking rod 29 is restrained to prevent it from slipping off the cylinder 28.

[0068] As the push rod 9 follows the movement of the piston rod of the tensile viscous damper 4, while driving the scale plate 8 to move, it also drives the marking rod 29 to move. The marking rod 29 generates friction with the marking carrier plate 26, which in turn leaves a graphite mark on the marking carrier plate 26. The result measured by the displacement of the scale plate 8 can be cross-verified with the result recorded by the graphite mark on the marking carrier plate 26, thereby improving the reliability of the measurement data. In the case that the scale plate 8 is mechanically stuck and cannot move, the part of the push rod 9 located inside the C-shaped plate 7 will break through the two broken notches 901, and the remaining part of the push rod 9 can continue to follow the movement of the piston rod of the tensile viscous damper 4, thereby driving the marking rod 29 to move accordingly, leaving a graphite mark on the marking carrier plate 26.

[0069] In this embodiment, by providing components such as a push rod 9 with a broken notch 901, a marking carrier plate 26, a marking rod 29, and a fixed frame 25, multi-channel recording of the extension and contraction data of the piston rod of the tensile viscous damper 4 is achieved. The marking rod 29 is quickly installed and firmly fixed through the pressure plate 31, the fixed slide rod 30 and the third spring 34. When the push rod 9 moves with the piston rod, it can not only push the scale plate 8 to record data, but also drive the marking rod 29 to leave a graphite mark on the marking carrier plate 26. The data of the two can be verified with each other, and the function of continuously obtaining data can be used when the scale plate 8 is stuck. It has the advantages of strong data recording reliability, complementary and redundant measurement methods, convenient installation and disassembly of components, and excellent fault response capabilities, effectively ensuring the integrity and accuracy of the operating data of the seismic isolation tensile device working throughout the earthquake process.
