Description

Technical Field

[0001] This invention relates to the field of seismic resistance technology, specifically to a seismic-resistant and resilient structure for underground structures in building engineering. Background Technology

[0002] Currently, my country is undergoing large-scale urban space development and construction, with rapid progress made in the construction of urban underground structures, exemplified by subways. Historical earthquake damage shows that during earthquakes, the gravity and vertical inertial forces of the overlying soil significantly increase the axial compression ratio of the columns in the underground structure and reduce its lateral deformation capacity. The columns are prone to failure due to insufficient lateral deformation capacity, leading to overall structural collapse. Since underground structures exist within the soil, their seismic response is constrained by the deformation of the surrounding rock and soil. Therefore, the key to reducing the seismic response of structures lies in reducing the horizontal deformation acting on the underground structure.

[0003] Traditional seismic isolation and mitigation measures for underground structures mainly focus on reducing the lateral deformation of the columns or increasing their lateral deformation capacity. These measures primarily address the seismic performance of underground structures while neglecting the recoverability of the structure's function after an earthquake. Even if an earthquake does not cause the building to collapse, structural deformation can still cause irreparable damage, rendering the building unusable. Therefore, there is an urgent need to develop a seismic-resistant and resilient underground structure for building engineering to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a seismic-resistant and resilient structure for underground structures in building engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A seismic-resistant and resilient structure for underground structures in building engineering, comprising:

[0007] Support columns, which are symmetrically arranged and fixedly connected to the soil;

[0008] The support mechanism is fixedly connected between the two support columns;

[0009] A buffer and shock absorption mechanism is provided on the outside of the support mechanism, slidably connected to the support column, and connected to the support mechanism, and is used to cooperate with the support mechanism to absorb lateral and longitudinal impact forces.

[0010] The buffer and shock absorption mechanism includes:

[0011] A buffer assembly is slidably connected between the two support columns to absorb horizontal impact forces and reset the support columns.

[0012] A connecting component is provided between the buffer component and the support mechanism, and is used to cooperate with the support mechanism to achieve longitudinal shock absorption and repositioning of the buffer component.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] During operation, the buffer components dissipate seismic energy through deformation, while simultaneously reducing the horizontal deformation acting on the underground structure. Meanwhile, the connecting components reduce the vertical deformation acting on the underground structure, thereby mitigating the seismic response of the underground structure and ensuring its stability. This also allows the device to reset, enabling stable operation after an earthquake and reducing resource consumption. The support mechanism not only works in conjunction with the buffer and damping mechanism to achieve vibration reduction but also enhances the stability and strength of the structure, further improving the safety and stability of the device. Compared to existing technologies that neglect the recoverability of the underground structure's function after an earthquake, this application, by setting up a buffer and damping mechanism and a support mechanism, and utilizing the buffer components and connecting components, not only reduces the horizontal and vertical deformation acting on the underground structure during an earthquake but also enables the device to reset, allowing stable operation after an earthquake and reducing resource consumption. Furthermore, the support mechanism enhances the stability and structural strength of the device. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0022] Please see Figure 1 In one embodiment of the present invention, a seismic toughness structure for underground structures in building engineering includes: support columns 1, which are symmetrically arranged and fixedly connected to the soil; a support mechanism, which is fixedly connected between the two support columns 1; and a buffer and damping mechanism, which is located outside the support mechanism, slidably connected to the support columns 1, and connected to the support mechanism, for cooperating with the support mechanism to absorb lateral and longitudinal impact forces; wherein, the buffer and damping mechanism includes: a buffer assembly, which is slidably connected between the two support columns 1, for absorbing horizontal impact forces and restoring the support columns 1; and a connecting assembly, which is located between the buffer assembly and the support mechanism, for cooperating with the support mechanism to achieve longitudinal damping and restoring of the buffer assembly.

[0023] In this embodiment, during operation, the buffer component dissipates seismic energy through deformation, while simultaneously reducing the horizontal deformation acting on the underground structure. Meanwhile, the connecting component reduces the vertical deformation acting on the underground structure, thereby reducing the seismic response of the underground structure and ensuring its stability. It also enables the device to reset, allowing it to continue operating stably after an earthquake, reducing resource consumption. The support mechanism not only works with the buffer and damping mechanism to achieve vibration reduction but also enhances the stability and strength of the structure, further improving the safety and stability of the device. Compared to existing technologies that neglect the recoverability of the underground structure's function after an earthquake, this application, by setting up a buffer and damping mechanism and a support mechanism, and utilizing the buffer component and connecting component, not only reduces the horizontal and vertical deformation acting on the underground structure during an earthquake but also enables the device to reset, allowing it to continue operating stably after an earthquake, reducing resource consumption. Furthermore, the support mechanism enhances the stability and structural strength of the device.

[0024] In one embodiment of the present invention, please refer to Figure 2The buffer assembly includes: a top plate 5, which is disposed between the two supporting columns 1 and connected to the supporting mechanism via a connecting assembly; a buffer member, which is disposed on both sides of the top plate 5, slidably connected to the supporting columns 1, and connected to the top plate 5 via a first elastic member 8; a buffer box 11, which is fixedly connected to the inner side of the top plate 5 and has a first damping fluid 13 disposed on its inner side; an energy-absorbing member, which is disposed between the buffer box 11 and the buffer member, and is used to cooperate with the buffer member to absorb the horizontal force on the structure; and an elastic metal plate 10, which is disposed between the buffer member and the buffer box 11 and abuts against the energy-absorbing member.

[0025] In this embodiment, the buffer includes a fixed plate 7 slidably connected to the shell walls at both ends of the top plate 5. A buffer plate 6 is fixedly connected to the outer side of the fixed plate 7, and a guide block 27 is fixedly connected to the outer side of the buffer plate 6. The guide block 27 is slidably connected to the support column 1. A first elastic element 8, which is a first spring, is fixedly connected between the other side of the buffer plate 6 and the top plate 5. The number of buffers is not less than three. Additionally, the energy-absorbing element includes energy-absorbing plates 12 slidably connected to both ends of the inner side of the buffer box 11. A sliding rod 9 is fixedly connected to the outer side and slidably connected to the buffer box 11. The sliding rod 9 is fixedly connected to the fixed plate 7. An elastic metal plate 10 is fixedly connected between the fixed plate 7 and the buffer box 11. The elastic metal plate 10 is located on the upper and lower sides of the sliding rod 9. By setting up a buffer assembly, the elastic element and energy-absorbing element can buffer and reduce the shock when the support column 1 is subjected to horizontal impact force, thereby reducing the horizontal deformation acting on the underground structure. In addition, the elastic metal plate 10 not only enhances the structural strength of the device, but also provides restoring force, realizing the rapid recovery of the structural function after the earthquake.

[0026] In one embodiment of the present invention, please refer to Figure 1 and Figure 4 The connecting component includes: a connecting seat 14, which is fixedly connected to the top plate 5, and has limiting blocks 15 fixedly connected to both sides and slidably connected to the support mechanism; and a shock-absorbing reset component, which is disposed between the connecting seat 14 and the support mechanism, and is used to cooperate with the support mechanism to absorb the longitudinal impact force received by the buffer component and realize the reset of the buffer component.

[0027] In this embodiment, the limiting block 15 is fixedly connected to both sides of the connecting seat 14. By setting the connecting component and using the shock-absorbing reset component, the vertical deformation acting on the underground structure can be reduced, and the reset of the buffer component can be realized, thereby enhancing the seismic resistance of the device.

[0028] In one embodiment of the present invention, the shock-absorbing and resetting component includes: a limiting member, which is fixedly connected to the support mechanism and slidably connected to the connecting seat 14; a second elastic member 18 for connecting the limiting member and the connecting seat 14, the second elastic member 18 being disposed between the limiting member and the connecting seat 14; and a compression member, which is fixedly connected to the connecting seat 14, slidably connected to the support mechanism, and connected to the support mechanism via an elastic ball 24.

[0029] In this embodiment, the limiting component includes a fixed rod 16 fixedly connected to the support mechanism. The other end of the fixed rod 16 is fixedly connected to a limiting plate 17 slidably connected to the inner side of the connecting seat 14. A second elastic element 18, which is a second spring, is fixedly connected between the limiting plate 17 and the inner wall of the connecting seat 14. Additionally, the compression component includes a vertical rod 22 fixedly connected to the connecting seat 14. A pressure plate 23 is fixedly connected to the outer side of the other end of the vertical rod 22. The pressure plate 23 is slidably connected to the support mechanism. A spring ball 24 is fixedly connected between the other end of the pressure plate 23 and the support mechanism. By providing a shock-absorbing and restoring component, and utilizing the second elastic element 18 and the spring ball 24, not only can the device achieve shock absorption, but it can also achieve post-vibration recovery. Furthermore, by providing the limiting component and the compression component, the stability and reliability of the connection assembly and the support mechanism during connection can be enhanced, which is beneficial for strengthening the structural strength of the device and further enhancing its seismic resistance.

[0030] In one embodiment of the present invention, the support mechanism includes: a bottom beam 4, which is fixedly connected between two side support columns 1, and a middle beam 3 fixedly connected to the support columns 1 is provided on the outer side; a top beam 2, which is provided on both sides of the connecting assembly and fixedly connected to the support columns 1; a support rod 19, which is fixedly connected between the bottom beam 4 and the middle beam 3; and a shock absorber, which is provided between the two side support rods 19 and connected to the limiting block 15, for cooperating with the movement of the connecting seat 14 to achieve shock absorption of the buffer assembly.

[0031] In this embodiment, by setting up a support mechanism, the middle beam 3 and the bottom beam 4 are used to connect the two side support columns 1, and several support rods 19 are fixedly connected between the middle beam 3 and the bottom beam 4, which can enhance the structural strength of the device and improve the stability of the structure. By setting up the top beam 2, the connecting components can be limited and guided to ensure the stability of the device when the connecting components are running. By setting up shock absorbers, the shock absorption capacity of the device can be further enhanced when the connecting components move, thereby ensuring that the buffer shock absorption mechanism can provide comprehensive and effective protection for the underground structure during an earthquake.

[0032] In one embodiment of the present invention, the shock absorber includes: a cavity disposed inside the support rod 19, and a second damping fluid 21 disposed inside the cavity; a movable member slidably disposed inside the cavity and connected to the support rod 19 via a third elastic member 20; and a connecting rod 29 for connecting the movable member and the limiting block 15, one end of the connecting rod 29 being hinged to the movable member and the other end being hinged to the limiting block 15.

[0033] In this embodiment, the movable component includes a baffle 31 slidably connected to the inner side of the cavity. A third elastic element 20, which is a third spring, is fixedly connected between the baffle 31 and the support rod 19. A movable rod 30 is fixedly connected to the outer side of the other end of the baffle 31. The movable rod 30 is slidably connected to the support rod 19 and the central beam 3, and a connecting rod 29 is rotatably connected to the inner side of the end away from the support rod 19. The other end of the connecting rod 29 is rotatably connected to the limiting block 15. When the connecting seat 14 moves, the limiting block 15 moves together with the connecting seat 14. The connecting block 15 drives the movable component to slide in the cavity through the connecting rod 29. The second damping fluid 21 and the third elastic element 20, which are disposed on the inner side of the cavity, can effectively absorb the impact force, thereby improving the shock absorption capacity of the connecting assembly for the buffer assembly.

[0034] In one embodiment of the present invention, please refer to Figure 1 and Figure 3 It also includes: a protective mechanism, which is located on the outside of the support columns 1 on both sides of the device and connected to the support mechanism, for cooperating with the support mechanism to protect the support columns 1; wherein, the protective mechanism includes: a protective plate 25, which is located on the side of the support column 1 away from the support mechanism and is slidably connected to the support column 1; a protective rod 26, which is fixedly connected to the protective plate 25 and has its other end slidably connected to the support mechanism; and a magnetic component, which is located between the protective rod 26 and the support mechanism, for cooperating with the support mechanism to absorb the impact force received by the protective plate 25.

[0035] In this embodiment, the magnetic component is a pair of magnets 28. The two magnets 28 have the same magnetism on opposite sides. The two magnets 28 are fixedly connected to the protective rod 26 and the support mechanism, respectively. The support mechanism is connected to the bottom beam 4 and the top beam 2, respectively. By setting up the protective mechanism, when the support column 1 is impacted, the protective plate 25 drives the protective rod 26 to slide, and the magnetic force between the magnets 28 on both sides is used to offset the impact force, thereby reducing the impact on the support column 1 and enhancing the stability of the device during use.

[0036] The seismic toughness structure of the underground structure of this building project, through the setting of buffer and damping mechanisms and support mechanisms, and the use of buffer components and connecting components, not only reduces the horizontal and vertical deformation of the underground structure during an earthquake, but also enables the device to reset, allowing the device to continue to operate stably after the earthquake, reducing resource consumption. The support mechanism enhances the stability and structural strength of the device. By setting up buffer components, using elastic elements and energy-absorbing elements, the support column 1 can buffer and dampen the horizontal impact force, thereby reducing the horizontal deformation of the underground structure. The use of elastic metal plate 10 not only enhances the structural strength of the device, but also provides restoring force, enabling rapid recovery of the structural function after the earthquake. By setting up connecting components, using damping and reset components, the vertical deformation of the underground structure can be reduced, and the reset of the buffer components can be achieved, thereby enhancing the seismic resistance of the device. By setting up damping and reset components, using the second elastic element 18 and elastic ball 24, not only can the device be damped, but the device can also be repositioned. The device is designed for post-earthquake recovery. By incorporating limiting and compression components, the stability and reliability of the connection components and support mechanisms during connection are enhanced, thereby increasing the structural strength of the device and further improving its seismic resistance. The support mechanism, utilizing the middle beam 3 and bottom beam 4 to connect the two side support columns 1, and with several support rods 19 fixedly connected between the middle beam 3 and bottom beam 4, enhances the structural strength and stability of the device. The top beam 2 limits and guides the connection components, ensuring the stability of the device during operation. The damping components further enhance the device's damping capacity during movement, ensuring the buffer and damping mechanism provides comprehensive and effective protection for the underground structure during earthquakes. The protective mechanism, when the support column 1 is impacted, causes the protective plate 25 to slide along the protective rod 26, using the magnetic force between the magnets 28 on both sides to offset the impact, thus reducing the impact on the support column 1 and enhancing the stability of the device during use.

[0037] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these should also be considered within the scope of protection of the present invention. These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
