Description

Technical Field

[0001] The invention relates to the technical field of building vibration isolation, in particular to a building vibration isolation and shock absorbing device capable of restoring the original position. Background Art

[0002] A shock-absorbing and vibration-isolating device is a device used to reduce the impact of shock, impact or vibration on a structure. It usually includes a base, a top seat and a vibration-isolating support for absorbing vibration. The vibration-isolating support is usually made of rubber or other deformable materials, which absorbs the energy generated by earthquakes through plastic deformation to offset or reduce the vibration effect. In addition, these devices usually include a supporting mechanism and a damping and limiting mechanism to further ensure the stability of the building and improve the seismic performance of the building.

[0003] However, existing seismic isolation and shock absorbing devices of this type still have shortcomings. For example, after an earthquake, the building will be displaced, and how to restore the building to its original position is a difficult problem in post-earthquake restoration work. Although there have been some attempts, the results are not ideal. For example, the commonly used method of restoring the building to its original position with the help of the elasticity of the spring sometimes causes the building to be reset further and further away. In addition, for large or high-rise buildings, the existing seismic isolation and shock absorbing devices have limited ability to control amplitude. If the vibration is too severe, it may still cause the building to shake and be damaged to a large extent. Moreover, the vibrations that the building is subjected to during its service are multi-directional, and the existing seismic isolation and shock absorbing devices cannot effectively consume the energy of multi-directional vibrations.

It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

[0031] See also Figures 1 to 7As shown, a seismic isolation and damping device for buildings that can be restored to their original positions according to an embodiment of the present application includes, from bottom to top, a base, a connection part and a top seat. The base 1 is located at the bottom and plays a stabilizing role, and the top seat 2 above is used to carry the main body of the building. The connection part is located above the base 1, connecting the base and the top seat, and includes a rubber vibration isolation support 4, a sensing column 10, a reset movable support mechanism 5, an auxiliary adjustment mechanism 6, a damping limit mechanism 7, a control box 8, a circular position sensor 9 and an edge connection mechanism 3. The rubber vibration isolation support 4 and the sensing column 10 are abutted to form a rubber seismic isolation structure, which absorbs and disperses the energy of the earthquake and reduces the damage to the building during the earthquake. The reset movable support mechanism 5 in the form of a circular ring resets the structure. The reset movable support mechanism 5 is located outside the rubber vibration isolation support 4 and is fixed between the base 1 and the top seat 2. Its arc-shaped contact surface is conducive to the reset and stability of the building. A part of the auxiliary adjustment mechanism 6 is fixed on the base, and the other part is fixed on the bottom end face of the top seat. The building is actively stabilized by magnetic force, so that the displacement of the superstructure is controlled within an acceptable range. The damping limit mechanism 7 connects the base 1 and the top seat 2, and plays a role in limiting severe displacement, thereby preventing the initial position of the building from being seriously deviated due to an earthquake. The control box 8 and the annular position sensor 9 are used as a monitoring and adjustment system. The annular position sensor 9 is fixed to the base 1, and captures and records the movement direction and acceleration changes of the sensing column 10, generates a displacement signal, and serves as a source of rotation force control signals for the auxiliary adjustment support 6, providing more accurate control, thereby improving the earthquake-proof effect of the entire system. Therefore, the device can protect buildings during earthquakes, reduce the damage caused by vibrations to buildings, and automatically reset the buildings after the earthquake to restore the buildings to their original state, thereby improving the efficiency of building repair after an earthquake.

[0032] In some examples, further, the seismic isolation and shock absorbing device for buildings that can be restored to their original position also includes an edge connection mechanism 3, which includes: a limit frame 31 and a mild steel guard plate 32. The limit frame 31 is fixedly arranged on the outer side of the side wall of the top seat 2, and a groove is provided on the inner side of the limit frame 31, and the bottom end of the groove is an open side. The limit frame 31 plays an auxiliary resetting and stabilizing role: once the building body is displaced after vibration, this limit frame 31 can help prevent the top seat 2 from excessive lateral displacement and cooperate with other mechanisms to restore it to its original position. The mild steel guard plate 32 is fixedly connected to the side wall of the base 1, and the top of the mild steel guard plate 32 is movably inserted in the groove on the inner side of the limit frame 31, and the middle part of the mild steel guard plate 32 is covered on the outside of the gap between the base 1 and the top seat 2. In this way, when an earthquake occurs, the displacement of the side wall of the base 1 and the top seat 2 can be effectively transmitted and controlled by the mild steel guard plate 32, ensuring the stability and safety of the entire mechanism and preventing excessive displacement and deformation caused by vibration. Therefore, the building seismic isolation and shock absorbing device which can be restored to its original position cleverly solves the problems that buildings are easy to deflect, difficult to reset and have poor stability during earthquakes.

[0033] In some examples, further, the groove opened in the limit frame 31 is movably mounted on the top of the mild steel guard plate 32, and a movable gap is left between the top of the mild steel guard plate 32 and the top inner wall of the inner cavity of the limit frame 31, and two adjacent mild steel guard plates 32 are not fixedly connected. This setting ensures greater freedom and elasticity, allowing each guard plate to respond independently, and also allows the seismic isolation and shock absorption device to control vibrations in different directions more carefully and comprehensively, more effectively reduce earthquake damage to buildings, and improve the ability of buildings to quickly recover to a safe state after an earthquake.

[0034] In some examples, further, the rubber vibration isolation support 4 includes: a fixed seat 41 and a rubber seat 42, the fixed seat 41 is fixedly formed on the top end surface of the base 1, and is a circular structure and is located in the middle of the device; the rubber seat 42 is fixedly arranged at the middle position of the top of the fixed seat 41, and the top of the rubber seat 42 is movably abutted against the bottom end of the sensing column 10. The rubber seat 42 can not only provide vertical support for the seismic isolation and damping device in static state, but also provide a certain displacement adjustment space for the seismic isolation and damping device during vibration, thereby enhancing the dynamic response capability of the entire device during earthquake. During an earthquake, the rubber seat 42 can disperse and absorb part of the seismic energy, and due to the characteristics of its material, it can quickly return to its original state after vibration, thereby achieving a shock absorption effect and avoiding excessive displacement of the building. Secondly, its movable abutment design with the sensing column 10 enables the seismic isolation and damping device to have a certain degree of adaptive capability. When the building is displaced during an earthquake, the rubber seat 42 can adjust its own position and drive the sensing column 10 to displace, which provides a signal source for the auxiliary adjustment support 6.

[0035] In some examples, further, the resetting movable support mechanism 5 includes: a circular ring support 51, a fixed ring 52, a movable ball 53 and a top contact seat 54, the circular ring support 51 is fixed on the top end face of the base 1 outside the rubber vibration isolation support 4, and a circular ring-shaped fixed ring 52 is also provided on the top of the circular ring support 51; a plurality of movable balls 53 can rotate freely and be clamped in the fixed ring 52, and a plurality of movable balls 53 are arranged equidistantly; the top contact seat 54 is fixedly arranged on the bottom end face of the top seat 2 and corresponds to the position of the circular ring support 51. A circular groove is provided on the bottom end face of the top contact seat 54, and the movable ball 53 abuts against the inner wall of the circular groove.

[0036] It should be noted that in the entire seismic isolation and shock absorbing device, the reset movable support mechanism 5 plays a key role, and is composed of a circular ring support 51, a fixed ring 52, a movable ball 53 and a top contact seat 54. The circular ring support 51 is fixed on the top end face of the base 1 outside the rubber vibration isolation support 4, and the fixed ring 52 arranged on its top is used to accommodate the movable ball 53. This fixing method allows the movable ball 53 to rotate freely. This design also allows the movable ball 53 to move freely in the circular groove during an earthquake, ensuring the stability of the building during the earthquake. The free rotation of the movable ball 53 also allows the structure to automatically reset to the state before the earthquake. Therefore, the reset movable support mechanism 5 can not only effectively dissipate earthquake energy, but also realize the self-reset of the building, greatly improving the seismic resistance of the building and enhancing the recoverability of the building.

[0037] In some examples, further, the curvature of the cross-sectional edge of the movable ball 53 is greater than the curvature of the circular groove, and the movable ball 53 is arranged in the middle of the circular groove in a centered state, and the movable ball 53 has a movable gap in any direction in the circular groove. Since the curvature of the movable ball 53 is large, it has enough movable gap in the groove, allowing it to slide freely and return to its original position after the vibration, thereby realizing the function of automatic reset. This unique design ensures that no matter how the vibration direction changes, the seismic isolation and shock absorption device can quickly return to its original state after the earthquake ends, reducing unnecessary damage and greatly enhancing the seismic resilience of the building.

[0038] In some examples, further, the auxiliary adjustment mechanism includes: an auxiliary top support 61, an annular metal frame 62 and a force-applying component 63, wherein the auxiliary top support 61 is adjacently arranged on the outside of the top contact seat 54, and the bottom end of the auxiliary top support 61 is fixedly connected with the annular metal frame 62; the cross-section of the annular metal frame 62 is "n"-shaped, wherein the open side faces downward; the force-applying component 63 is fixedly arranged on the top end face of the base 1, and is in the shape of a circular ring, and the force-applying component 63 is located in the annular metal frame 62, and is concentric with the annular metal frame 62 and non-contacted. The non-contact design allows the force-applying component 63 to move freely during a vibration event to adapt to the displacement of the building during the vibration, and to recover quickly after the vibration ends, to achieve self-repair, and to reduce the damage that vibration events such as earthquakes may cause to the building.

[0039] In some examples, further, the force-applying assembly 63 includes: a placement ring 631 and an electromagnetic member 632, wherein the placement ring 631 is fixedly placed at the top of the base 1, wherein the placement ring 631 has a plurality of equidistantly arranged cavity structures facing the center of the safety ring, and wherein the electromagnetic member 632 is fixedly placed in the placement ring 631. As the core part of the auxiliary adjustment mechanism, the force-applying assembly 63 provides the entire seismic isolation and damping device with the ability of active control. The placement ring 631 is fixed at the top of the base 1, and there are a plurality of equidistantly arranged cavity structures facing the center of the ring inside. Such a design can apply force at multiple angles, providing the seismic isolation and damping device with the ability to counteract multi-directional vibrations. The electromagnetic member 632 is fixedly placed in the placement ring 631, and its working principle is that when the sensing column 10 and the auxiliary adjustment support 6 sense the direction of the vibration, the electromagnetic member 632 will generate a magnetic field, apply additional magnetic force to the annular metal frame 62 and the movable ball 53, and adjust the position of the metal frame and the movable ball 53 to change the supporting force of the overall structure, thereby offsetting the impact of the vibration. After an earthquake, the electromagnetic component 632 will actively adjust the positions of the mounting ring 631, the annular metal frame 62 and the movable ball 53 to achieve rapid self-repair of the seismic isolation and shock absorbing device, greatly enhancing the seismic resistance and post-earthquake recovery capabilities of the building.

[0040] In some examples, further, all of the electromagnetic components 632 are electrically connected to the control box 8 , and a grouping module is also provided in the control box 8 , and the grouping module is used to perform grouping and synchronous control on the plurality of electromagnetic components 632 .

[0041] It should be noted that the control box 8 and the grouping module inside it uniformly manage and coordinate the control of all electromagnetic components 632, and implement more refined grouping strategies based on factors such as location and structural safety status, thereby achieving refined seismic protection and reducing damage to buildings caused by earthquake vibrations.

[0042] In some examples, further, the damping limit mechanism 7 includes two groups of embedded structures, one group of embedded structures is formed in the base 1, and the other group of embedded structures is formed in the top seat 2, each group of embedded structures includes a limit seat 71 and a rotating column 72 that can rotate in the limit seat 71, the end of the rotating column 72 extends outside the limit seat 71, and the damping connector 74 is rotatably connected between the ends of the two rotating columns 72 through a hinge seat 73. During vibration, these embedded structures move through the limit seat 71 and the rotating column 72 that can rotate therein, which can effectively absorb a part of the vibration energy and play a damping role, and the end of the rotating column 72 is connected with a damping connector 74, which provides double damping protection for the damping limit mechanism 7. When the building vibrates, the rotating column 72 rotates in the limit seat 71, and the two groups of rotating columns 72 work together through the damping connector 74 to further absorb vibration energy and prevent large-scale vibration from causing damage to the building, thereby improving the seismic resistance of the building and further reducing the damage that may be caused to the building by vibration events such as earthquakes.
