Description

Technical Field

[0001] This application relates to the field of vibration isolators, and in particular to an ultra-thin, high-load-bearing, pre-tightening spring vibration isolator, a spring-rubber vibration dual-control support, and a spring-friction pendulum vibration dual-control support. Background Technology

[0002] With the development of the TOD (Transit-Oriented Development) model, buildings above public transportation such as subways and light rail lines have gradually become carriers of livable urban life, fully demonstrating their outstanding value in optimizing environmental resource allocation and reshaping urban spatial patterns. However, these buildings not only need to consider the instantaneous impact of earthquakes, but also the vibrations generated by the long-term operation of public transportation. Currently, vibration isolation is generally achieved through vibration isolators.

[0003] Reference Figure 1 This type of steel spring vibration isolator, widely used in practical engineering, mainly consists of a steel spring 1, a cover plate 2, a support plate 3, through bolts 4, and an auxiliary plate 11. The cover plate 2 includes an upper cover plate 21 and a lower cover plate 22. The steel spring 1 is fixed between the upper cover plate 21 and the lower cover plate 22, and the through bolts 4 pass through the upper cover plate 21 and the lower cover plate 22. When the building is subjected to a vertical impact force, the upper cover plate 21 will compress the steel spring 1, causing the upper end of the through bolts 4 to protrude from the upper cover plate 21. Therefore, a support plate 3 for connecting with external buildings is also fixed on the upper cover plate 21. An auxiliary plate 11 is fixed between the support plate 3 and the upper cover plate 21. A placement space 101 for embedding the through bolts 4 is formed between the support plate 3 and the upper cover plate 21. When the upper cover plate 21 is compressed by force, the end of the through bolts 4 will be embedded in the placement space 101 to avoid obstructing the external buildings. However, this also increases the overall height of the steel spring vibration isolation, thus affecting the effective usable space of the building. The increased height directly raises the center of gravity of the building, resulting in a decrease in the overall integrity of the vibration isolator. Under the action of seismic shear waves and lateral forces generated by strong winds, it is more prone to lateral tilting. Utility Model Content

[0004] In order to avoid obstructing the through bolts and external buildings when the upper cover plate is compressed by the steel spring, and at the same time reduce the overall height of the steel spring vibration isolation, this application provides an ultra-thin high load-bearing capacity pre-tightening spring vibration isolator, a spring rubber vibration dual-control support and a spring friction pendulum vibration dual-control support.

[0005] In the first aspect, this application provides an ultra-thin, high-load-bearing, pre-tightening spring vibration isolator, which adopts the following technical solution: An ultra-thin, high-load-bearing, pre-tightening spring vibration isolator includes a cover plate, which comprises an upper cover plate and a lower cover plate. An elastic device is provided between the upper cover plate and the lower cover plate. The device also includes a connecting plate disposed between the upper cover plate and the lower cover plate. The connecting plate includes an upper connecting plate fixed to the side of the upper cover plate facing the lower cover plate and a lower connecting plate fixed to the side of the lower cover plate facing the upper cover plate. Both the upper connecting plate and the lower connecting plate have L-shaped cross sections. A through bolt is provided between the upper connecting plate and the lower connecting plate. Embedded spaces for the through bolt are formed between the upper connecting plate and the upper cover plate and between the lower connecting plate and the lower cover plate.

[0006] By adopting the above technical solution and setting the embedded space between the upper and lower cover plates, the overall height of the steel spring vibration isolator is reduced, the center of gravity of the building is lowered, the overall stability is enhanced, and the through bolts can achieve the pre-tightening effect, making the vibration isolation device easier to adapt to the installation environment.

[0007] Optionally, both the upper connecting plate and the lower connecting plate are rectangular in shape, and multiple upper connecting plates and lower connecting plates are provided.

[0008] By adopting the above technical solution, the rectangle makes the connecting plate more stable as a whole, and can form a larger embedded space. Only by setting multiple connecting plates can a structure with the ends connected be presented.

[0009] Optionally, multiple upper connecting plates are connected end-to-end and sleeved on the outside of the elastic device, and multiple lower connecting plates are connected end-to-end and sleeved on the outside of the elastic device.

[0010] By adopting the above technical solution, multiple upper connecting plates or multiple lower connecting plates are set on the outside of the elastic device, which can protect the elastic device and at the same time facilitate the pre-tightening of the through bolts on the outside.

[0011] Optionally, a limiting device is provided between the upper cover plate and the lower cover plate. One end of the limiting device is fixedly connected to one end of the upper connecting plate or the lower connecting plate, and the other end is left with a gap between it and the lower connecting plate or the upper connecting plate.

[0012] By adopting the above technical solution, the limiting device is set between the upper and lower cover plates, which increases the overall support force of the support, and at the same time, it fits with the two adjacent upper or lower connecting plates to play a circumferential limiting role.

[0013] Optionally, the two adjacent upper connecting plates are arranged at right angles, and the limiting device is an L-shaped angle steel with the two L-shaped sides of the angle steel respectively attached to the two adjacent upper connecting plates or respectively attached to the two adjacent lower connecting plates.

[0014] By adopting the above technical solution, the right angle setting and the L-shaped cross section of the limiting device allow the upper connecting plate and the limiting device to fit together, thus achieving better circumferential limiting.

[0015] Optionally, the elastic device can be any one of the following elastic materials: steel spring, polyurethane, or disc spring.

[0016] By adopting the above technical solution, the elastic device can use other elastic materials with better performance than steel springs, thereby enhancing its deformation capacity.

[0017] Optionally, multiple upper ribs are fixedly connected to the L-shaped opening of the upper connecting plate, and the multiple upper ribs are spaced apart along the length direction of the upper connecting plate. Multiple lower ribs are fixedly connected to the L-shaped opening of the lower connecting plate, and the multiple lower ribs are spaced apart along the length direction of the lower connecting plate.

[0018] By adopting the above technical solution, the arrangement of multiple ribs can enhance the supporting force of the connecting plate.

[0019] Optionally, the upper rib is fixedly connected to both the upper connecting plate and the upper cover plate, and the lower rib is fixedly connected to both the lower connecting plate and the lower cover plate.

[0020] By adopting the above technical solution, the rib plate can increase the supporting force between the upper cover plate and the upper connecting plate or the lower cover plate and the lower connecting plate.

[0021] Secondly, this application provides a high-load-bearing capacity, pre-tightened spring-rubber vibration dual-control support, which adopts the following technical solution: A low-profile, high-load-bearing, pre-tightening spring-rubber vibration dual-control support includes the aforementioned ultra-thin, high-load-bearing, pre-tightening spring vibration isolator and a rubber support, wherein the rubber support is fixedly connected to the upper cover plate.

[0022] By adopting the above technical solution, the vibration isolator can simultaneously isolate horizontal and vertical vibrations.

[0023] Thirdly, this application provides a low-profile, high-load-bearing, pre-tensioned spring friction swing vibration dual-control support, which adopts the following technical solution: A low-profile, high-load-bearing, pre-tightening spring friction pendulum vibration dual-control support includes the aforementioned ultra-thin, high-load-bearing, pre-tightening spring vibration isolator and a friction pendulum support, wherein the friction pendulum support is fixedly connected to the upper cover plate.

[0024] By adopting the above technical solution, the vibration isolator can simultaneously isolate horizontal and vertical vibrations.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By placing the embedded space between the upper and lower cover plates, it not only provides excellent support but also reduces the overall height of the steel spring vibration isolation, thereby lowering the building's center of gravity and enhancing overall stability; 2. Through bolts can achieve a pre-tightening effect, making the vibration isolation device easier to adapt to the installation environment; 3. The limiting device simultaneously engages with two adjacent upper or lower connecting plates to provide circumferential limiting. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 2-5 This application will be described in further detail.

[0033] This application discloses an ultra-thin, high-load-bearing, pre-tightening spring vibration isolator. The ultra-thin, high-load-bearing, pre-tightening spring vibration isolator includes a cover plate 2, through bolts 4, a connecting plate 5, and an elastic device 6.

[0034] The cover plate 2 includes an upper cover plate 21 and a lower cover plate 22, with the elastic device 6 fixed between the upper cover plate 21 and the lower cover plate 22. The connecting plate 5 includes an upper connecting plate 51 fixed to the side of the upper cover plate 21 facing the lower cover plate 22 and a lower connecting plate 52 fixed between the lower cover plate 22 and the upper cover plate 21. The upper connecting plate 51 and the lower connecting plate 52 can be circular or rectangular as a whole. When the upper connecting plate 51 and the lower connecting plate 52 are circular, one upper connecting plate 51 and one lower connecting plate 52 are provided, and they are fitted onto the elastic device 6. When the upper connecting plate 51 and the lower connecting plate 52 are rectangular as a whole, multiple upper connecting plates 51 and multiple lower connecting plates 52 are connected end to end to form a regular polygon, and multiple upper connecting plates 51 and multiple lower connecting plates 52 are fitted onto the outside of the elastic device 6. In this application, four upper connecting plates 51 and lower connecting plates 52 are connected end to end as an example, with adjacent upper connecting plates 51 arranged at right angles. Through bolts 4 are inserted into the upper connecting plates 51 and lower connecting plates 52. Both upper connecting plates 51 and lower connecting plates 52 have L-shaped cross-sections, creating recessed spaces 102 between the upper connecting plate 51 and the upper cover plate 21, and between the lower connecting plate 52 and the lower cover plate 22, for the through bolts 4 to be embedded. When the upper cover plate 21 is subjected to external impact force that compresses the elastic device 6, the ends of the through bolts 4 are embedded in the recessed spaces 102, preventing contact with external buildings and thus avoiding obstruction. This effectively utilizes building space. Simultaneously, the overall height of the vibration isolator is reduced, and the building's center of gravity shifts downward accordingly. Under the influence of seismic shear waves and strong winds, the overturning resistance of the low-center-of-gravity structure is significantly enhanced.

[0035] Of course, the through bolt 4 can also achieve a pre-tightening effect. That is, before installing the vibration isolator, the nut on the through bolt 4 is tightened first, so that the upper cover plate 21 and the lower cover plate 22 compress the elastic device 6. After the construction is completed, the nut on the through bolt 4 is loosened, so that the elastic device 6 is released.

[0036] The elastic device 6 can be a steel spring, or it can be made of elastic materials such as polyurethane or disc spring.

[0037] Reference Figure 2 To increase the overall support strength of the upper connecting plate 51 and the lower connecting plate 52, an upper rib plate 71 is fixedly connected to the L-shaped opening of the upper connecting plate 51, and multiple upper rib plates 71 are spaced apart along the length of the upper connecting plate 51. Similarly, a lower rib plate 72 is fixedly connected to the L-shaped opening of the lower connecting plate 52, and multiple lower rib plates 72 are spaced apart along the length of the lower connecting plate 52. The upper rib plate 71 is fixedly connected to both the upper connecting plate 51 and the upper cover plate 21, and the lower rib plate 72 is fixedly connected to both the lower connecting plate 52 and the lower cover plate 22.

[0038] To increase the overall support force of the upper cover plate 21 and the lower cover plate 22 for the vibration isolator, and at the same time to achieve circumferential limitation of the vibration isolator, a limiting device 8 for circumferential limitation of the vibration isolator is provided between the upper cover plate 21 and the lower cover plate 22. The limiting device 8 can be an angle steel with an L-shaped cross section. Four angle steels are also provided corresponding to the upper connecting plate 51 and the lower connecting plate 52. The four angle steels are located at the connection of the four upper connecting plates 51 or at the connection of the four lower connecting plates 52, so that the two L-shaped plates of the angle steel are respectively attached to the two adjacent upper connecting plates 51 or the two lower connecting plates 52, thereby limiting the upper cover plate 21 and the lower cover plate 22.

[0039] Specifically, one end of the angle steel is fixed to the upper connecting plate 51, and the other end is left with a gap between it and the lower connecting plate 52 to accommodate the compression deformation of the elastic device 6. When the vertical impact force on the upper cover plate 21 is too large, the two ends of the angle steel will abut against the upper cover plate 21 and the lower cover plate 22 respectively, playing a load-bearing role to increase the overall support force of the vibration isolator of this application.

[0040] Of course, one end of the angle steel can be fixed to the lower connecting plate 52, and the other end can be left with a gap between it and the upper connecting plate 51. As long as it can achieve circumferential limiting of the vibration isolator and adapt to the compression deformation of the elastic device 6, it is acceptable.

[0041] Reference Figure 2 The lower cover plate 22 has mounting holes for fixing the lower cover plate 22 to the building foundation by installing through bolts 4.

[0042] The implementation principle of Embodiment 1 of this application is as follows: When in use, pre-tightening can be performed as needed. First, the nut on the through bolt 4 is screwed on. The through bolt 4 can drive the upper cover plate 21 and the lower cover plate 22 to move relative to each other, thereby squeezing the elastic device 6 and realizing the pre-tightening function of the vibration isolator.

[0043] When the building is subjected to vertical impact, the upper cover plate 21 and the lower cover plate 22 are compressed by the elastic device 6, which is made of elastic material, thus undergoing compression deformation. The through bolt 4 is embedded in the recessed space 102 formed by the upper connecting plate 51 and the upper cover plate 21, without obstructing the building, and achieves the functions of buffering and shock absorption. At the same time, the overall height of the vibration isolator is reduced, improving the overall performance. The through bolt 4 is fixed to the upper connecting plate 51 and the lower connecting plate 52 by nuts, and also plays a role in vertical limiting when the vertical impact is large.

[0044] When the external building is subjected to circumferential impact, the limiting device 8 is fixed to the upper cover plate 21 or the lower cover plate 22 in an L-shape, and is close to the upper connecting plate 51 and the lower connecting plate 52. When the limiting device 8 is subjected to circumferential impact, it will undergo circumferential rotational displacement. However, because the limiting device 8 is close to the upper connecting plate 51 and the lower connecting plate 52, the circumferential rotational displacement of the limiting device 8 is limited, thereby ensuring the overall stability of the vibration isolator.

[0045] This application also discloses a spring-rubber vibration dual-control support. (Refer to...) Figure 4 The spring-rubber vibration dual-control bearing includes the aforementioned ultra-thin, high-load-bearing, pre-tightening spring vibration isolator and a rubber bearing 91, which is fixedly connected to the upper cover plate 21. The rubber bearing 91 can be an existing rubber bearing capable of achieving horizontal vibration isolation.

[0046] This application also discloses a spring-friction pendulum vibration dual-control support. (Refer to...) Figure 5 The spring friction pendulum vibration dual-control support includes the aforementioned ultra-thin, high-load-bearing, pre-tightening spring vibration isolator and a friction pendulum support 92, which is fixedly connected to the upper cover plate 21. The friction pendulum support 92 can be an existing friction pendulum vibration isolation support capable of achieving horizontal vibration isolation.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
