[0024] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. 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. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0026] In the field of architectural design, large steel storage tanks are tall and heavy, and especially under earthquakes, they will generate large horizontal forces, causing large bending moments at the base of the tank, resulting in lower safety of the tank.

[0027] In response, this application proposes a seismic isolation component 100.

[0028] like Figure 1 As shown, the seismic isolation assembly 100 includes: a support base 10, a seismic isolation bearing 12, and a viscous damper 30.

[0029] The support base 10 is provided with an installation groove 11, the damping component is adapted to extend into the installation groove 11, the seismic isolation support 12 is provided on the bottom wall of the installation groove 11 and is used to support and connect with the damping component, and the viscous damper 30 is connected between the bottom wall of the installation groove 11 and the damping component and is spaced apart from the seismic isolation support 12.

[0030] It is understood that the damping component can be a large steel storage tank, a large structure or other building structure, etc. The damping component can be placed on the support 10, and the bottom of the damping component can extend into the mounting groove 11 to abut against the seismic isolation bearing 12 and the viscous damper 30, so that the seismic isolation bearing 12 and the viscous damper 30 jointly support the damping component. In this way, the natural vibration period of the storage tank 200 can be increased by using the seismic isolation bearing 12, thereby reducing the seismic force on the storage tank 200 and consuming seismic energy, thus reducing the impact of earthquakes on the storage tank 200 and improving the safety of the storage tank 200. Furthermore, the seismic energy can be consumed by using the viscous damper 30. That is, the seismic energy can be consumed in multiple ways by using the seismic isolation bearing 12 and the seismic isolation cavity 21, thereby reducing the impact of earthquakes on the storage tank 200 and improving the safety of the storage tank 200. At the same time, the setting of the viscous damper 30 can indirectly reduce the structural requirements such as the specifications of the seismic isolation bearing 12 and the width of the seismic isolation cavity 21, as well as other costs that increase with the increase of displacement.

[0031] According to the embodiment of this application, the seismic isolation component 100 can increase the natural vibration period of the storage tank 200 by using the seismic isolation bearing 12 to reduce the seismic force on the tank body 202. At the same time, the viscous damper 30 can also absorb some of the vibration energy. In this way, the seismic energy can be consumed in multiple ways by using the seismic isolation bearing 12 and the seismic isolation cavity 21, thereby reducing the impact of earthquakes on the storage tank 200 and improving the safety of the storage tank 200.

[0032] In some embodiments, such as Figure 1 As shown, the distance from the viscous damper 30 to the centroid of the support 10 is less than the distance from the seismic isolation bearing 12 to the centroid of the support 10.

[0033] This makes the seismic isolation bearing 12 further away from the centroid of the support 10 relative to the viscous damper 30, that is, the seismic isolation bearing 12 is positioned closer to the outer side of the support 10 relative to the viscous damper 30, so as to facilitate the inspection and replacement of the seismic isolation bearing 12.

[0034] In some embodiments, such as Figure 1 As shown, the seismic isolation bearing 12 is constructed as a cylindrical structure. The bottom wall of the mounting groove 11 and the damping component are respectively connected to the two ends of the cylindrical structure along the axis. The direction of the damping force of the viscous damper 30 is perpendicular to the axis of the seismic isolation bearing 12.

[0035] In this way, the direction of the damping force of the viscous damper 30 is horizontal, that is, the direction of the damping force of the viscous damper 30 can be matched with the direction of the horizontal force of the mounting base 300, thereby applying a damping force when the mounting base 300 is subjected to a horizontal force, thereby reducing the horizontal movement tendency of the mounting base 300.

[0036] In some embodiments, such as Figure 2As shown, the viscous damper 30 is disposed at the centroid of the support 10. That is, the orthographic projection of the viscous damper 30 onto the support 10 falls on the centroid of the support 10.

[0037] It is understandable that when the support is a circular component, and the damping component is the storage tank 200, the cross-section of the storage tank 200 is usually circular, and the center of the cross-section of the storage tank 200 usually coincides with the center of the support in the height direction. At this time, the centroid of the support 10 is the center of the circle. Therefore, by setting the viscous damper 30 at the centroid of the support 10, when the storage tank 200 generates a large horizontal force due to the earthquake, the viscous damper 30 can provide a horizontal damping force to the storage tank 200 at the centroid of the support 10, thereby reducing the horizontal force generated by the storage tank 200.

[0038] In some embodiments, such as Figure 2 As shown, there are multiple seismic isolation bearings 12, which are arranged around the centroid of the support base 10.

[0039] Therefore, multiple seismic isolation bearings 12 can be used to increase the support for the storage tank 200, and it is also beneficial to increase the natural vibration period of the storage tank 200 by using multiple seismic isolation bearings 12, thereby reducing the seismic force on the tank body 202.

[0040] In some embodiments, such as Figure 1 As shown, the seismic isolation assembly 100 also includes a foundation pile 40, which is disposed on the side of the support 10 away from the mounting groove 11. In the depth direction of the mounting groove 11, the projection of the seismic isolation support 12 falls on the centroid of the foundation pile 40.

[0041] In this way, the foundation piles 40 can be used to support the support base 10, and the foundation piles 40 can be used to increase the height of the support base 10 above the ground, thereby meeting the usage requirements of the support base 10. In particular, in the depth direction of the mounting groove 11, the projection of the seismic isolation bearing 12 falls on the centroid of the foundation pile 40. This allows the weight of the storage tank 200 to be better applied to the foundation pile 40 through the seismic isolation bearing 12, thereby making the weight distribution of the storage tank 200 more balanced.

[0042] In some embodiments, the mounting base 300 is provided with anchor bolts, and the centroid of the seismic isolation support 12 coincides with that of the anchor bolt in the depth direction of the mounting groove 11.

[0043] This allows the storage tank 200 to be directly fixed to the ground using anchor bolts, thus reducing the difficulty of arranging the storage tank 200. The centroids of the seismic isolation bearing 12 and the anchor bolts coincide, allowing the mounting base 300 to be connected to the seismic isolation bearing 12 using anchor bolts, thereby reducing the difficulty of connecting the mounting base 300 and the seismic isolation bearing 12.

[0044] In some embodiments, the seismic isolation assembly 100 further includes: a mounting base 300, a seismic isolation support 12 and a viscous damper 30, all supported between the bottom wall of the mounting groove 11 and the mounting base 300. The damping element is adapted to be fixed to the mounting base 300, thereby increasing the contact area with the damping element by utilizing the mounting base 300. The support base 10 is provided with a mudguard 20, which defines a seismic isolation cavity 21 that opens toward the direction away from the bottom wall of the mounting groove 11 between the mudguard 20 and the mounting base 300. The seismic isolation cavity 21 is arranged around the mounting base 300, that is, the mudguard 20 and the mounting base 300 are spaced apart in the horizontal direction. This facilitates the use of the seismic isolation cavity 21 to provide space for the horizontal deformation of the mounting base 300 under earthquakes.

[0045] In some embodiments, such as Figure 1 As shown, the vibration isolation assembly 100 also includes a cover plate 50, which is connected between the mounting base 300 and the mudguard 20, and the cover plate 50 is used to cover the opening of the vibration isolation cavity 21.

[0046] This makes the isolation cavity 21 relatively enclosed, preventing foreign objects from entering the isolation cavity 21, thereby ensuring the space between the mudguard 20 and the mounting base 300 in the horizontal direction, and thus ensuring that the isolation cavity 21 can provide space for the horizontal deformation of the mounting base 300 under earthquake.

[0047] In some embodiments, the cover plate 50 is made of a brittle material. It is understood that a brittle material refers to a material that breaks and fractures with only a small deformation under external forces (such as tension, impact, etc.). In this way, when the mounting base 300 generates horizontal forces due to an earthquake, the cover plate 50 can break under the force, thereby consuming some of the seismic energy. Then, the horizontal swaying of the mounting base 300 can be further consumed by the viscous damper 30, thereby improving the seismic resistance of the storage tank 200.

[0048] In some embodiments, the cover plate 50 is slidably mounted on the mudguard 20 and is used to cover the opening of the vibration isolation cavity 21.

[0049] It is understandable that when the mounting base 300 generates a horizontal force due to an earthquake, the mounting base 300 pushes the cover plate 50 to slide in the horizontal direction, thereby consuming some of the earthquake energy and helping to reduce the interference between the cover plate 50 and the mounting base 300.
