[0025] like Figures 1 to 5 As shown, a schematic diagram of an embodiment of an adjustable seismic isolation bearing of the utility model includes a bearing body 1 for seismic isolation, and also includes a base 2 and an adjustment mechanism arranged below the bearing body 1. The adjustment mechanism includes a lower support member 4 connected to the base 2 and an upper support member 3 connected to the bearing body 1. The top surface of the lower support member 4 and the bottom surface of the upper support member 3 are adaptive inclined surfaces to adjust the height.

[0026] In this embodiment, the support body 1 includes an upper connecting seat, a lower connecting seat, and a compressible buffer body installed between the upper connecting seat and the lower connecting seat. The buffer body can be made of rubber material to isolate vibrations.

[0027] In this embodiment, a fitting groove is provided on the top surface of the lower support member 4, and a fitting protrusion that matches the fitting groove is provided on the bottom surface of the upper support member 3 for fixation. The inclined surfaces of the upper support member 3 and the lower support member 4 can be designed to fit together, which is convenient for installation and fixation during construction, and can also improve the stability of fixation. The shape of the fitting protrusion can be a triangle, etc. In this embodiment, the inclined surfaces of the upper support member 3 and the lower support member 4 are set to fit together. The stepped shape is easy to manufacture, easy to process and promote, and can effectively ensure the strength of the seismic isolation bearing, ensure the processing cost, and improve the stability of the structural connection. In different embodiments, by reducing the thickness of each step, increasing the level of the gradient, and improving the accuracy of the height adjustment, the upper support member 3 and the lower support member 4 can be directly fitted together to achieve the desired height, and a one-time adjustment can be made to improve the installation efficiency. In this embodiment, the upper support member 3 is provided with a plurality of upper mounting holes 32 with internal threads, which are used for detachable connection with the support body 1. The upper support member 3 is threadedly connected to the upper connecting seat through the upper mounting holes 32 and fastening bolts adapted to the upper mounting holes 32; the lower support member 4 is also provided with a plurality of lower mounting holes 42 with internal threads, which are used for detachable connection with the base 2. The detachable connection method is convenient for storage, facilitates later maintenance, and ensures maintenance costs.

[0028] In this embodiment, the adjustment mechanism further includes a plurality of adjustment members 5, the two ends of each adjustment member 5 being movably connected to the upper support member 3 and the lower support member 4 to adjust the distance between the upper support member 3 and the lower support member 4. In this embodiment, the adjustment member 5 can be made of bolts, and the two ends of the adjustment member 5 are respectively threadedly connected to the upper support member 3 and the lower support member 4. In this embodiment, the upper support member 3 and the lower support member 4 are designed to fit together so that the height of the support body 1 can be adjusted by moving the upper support member 3 and the lower support member 4 relative to each other; the spacing between the upper support member 3 and the lower support member 4 can be adjusted by the adjustment member 5, and the height of the support body 1 can be precisely adjusted within the thickness of a step. The structure is simple and easy to operate, and it is particularly suitable for installation on uneven foundations. It has a wide range of applicability and can also improve the stability of the superstructure and ensure construction quality.

[0029] In this embodiment, multiple adjustment members 5 can be spaced apart along the relative movement direction of the upper support member 3 and the lower support member 4. For example, when the upper support member 3 and the lower support member 4 are moved in the left-right direction to adjust their height, the multiple adjustment members 5 are spaced apart from left to right between the upper support member 3 and the lower support member 4. In this embodiment, when the installation location is tilted, the multiple adjustment members 5 can be used to fine-tune the upper support member 3 and the lower support member 4 from left to right to different spacings to adjust the level, thereby ensuring the levelness of the support body 1, thereby improving construction quality and enhancing the stability of the superstructure. This is particularly suitable for construction on uneven foundations.

[0030] In this embodiment, the upper support member 3 is provided with a plurality of upper adjustment holes 31 , and the lower support member 4 is provided with a plurality of lower adjustment holes 41 corresponding to the upper adjustment holes 31 and fixed by pouring concrete.

[0031] The upper adjustment hole 31 and the lower adjustment hole 41 can not only be used for pouring concrete to fix, but also have internal threads for installing the adjustment member 5. In this embodiment, each step of the stepped slope includes a step transverse surface 6 and a step vertical surface. Each upper adjustment hole 31 only penetrates one step transverse surface 6. Each step transverse surface 6 of the upper support member 3 is provided with at least one upper adjustment hole 31, and multiple upper adjustment holes 31 are evenly distributed. In this embodiment, each upper adjustment hole 31 has a double aperture, which includes a fastening hole 311 with an internal thread and a limiting hole 312 connected to the fastening hole 311. The inner diameter of the fastening hole 311 is smaller than the inner diameter of the limiting hole 312 to form a stepped through hole. The length of each fastening hole 311 is equal, and the vertical length of each fastening hole 311 is less than the length of the adjustment member 5, so that the adjustment member 5 can be inserted into the upper adjustment hole 31 and the lower adjustment hole 41 at the same time.

[0032] A method for using an adjustable seismic isolation support includes the following steps:

[0033] Fix the base 2 at the installation location, move the upper support member 3 and the lower support member 4 relative to each other to adjust the height of the adjustment mechanism, and the upper support member 3 and the lower support member 4 fit each other through the stepped inclined surfaces, so that the upper support member 3 is erected on the lower support member 4, and the upper adjustment hole 31 is aligned with the lower adjustment hole 41 and fixed by pouring concrete, and the concrete is sealed on the surface of the base 2, so that the support body 1, the base 2 and the adjustment mechanism are interconnected to form a stable whole, and the height and level of the support body 1 are adjusted by the adjustment mechanism to be suitable for installation on uneven foundations, so as to better achieve the seismic isolation effect.

[0034] In this embodiment, not only can the height of the adjustment mechanism be roughly adjusted once via the stepped slope, but the adjustment member 5 can also be fine-tuned twice. That is, the distance between the upper support member 3 and the lower support member 4 can be adjusted by multiple adjustment members 5, thereby adjusting the height or level of the adjustment mechanism. The height of the support body 1 can be precisely adjusted within the thickness of a step to ensure that the support body 1 is installed horizontally. The spacing between the upper support member 3 and the lower support member 4 can be filled and fixed by pouring concrete. The concrete filling method can be achieved by pouring concrete into the upper adjustment hole 31, and the concrete flows under the action of gravity and fills the gap. During pouring, a partition can be installed outside the adjustment mechanism to block the concrete. In different embodiments, the thickness of each step can be reduced and the level of the height gradient can be increased, so that the upper support member 3 and the lower support member 4 can be directly aligned to achieve the desired height. A single adjustment can improve installation efficiency.

[0035] In this embodiment, the upper support member 3 is provided with a plurality of upper adjustment holes 31 extending vertically therethrough. This vertical arrangement facilitates the flow of concrete under gravity after pouring, thereby improving construction efficiency. The upper and lower adjustment holes 31, 41 also include threads adapted to the adjustment member 5 for mounting the adjustment member 5. In this embodiment, the upper adjustment holes 31 and lower adjustment holes 41 are coaxially disposed with each other, and the adjustment member 5 is inserted into the corresponding upper and lower adjustment holes 31, 41 to fix the spacing between the upper support member 3 and the lower support member 4.

[0036] In this embodiment, the upper support member 3 and the lower support member 4 have the same structure. Not only is it easy to process, but any two of them can be matched into pairs at will, the production cost is low, and it is easy to promote and apply. In this embodiment, the upper mounting hole 32 and the lower mounting hole 42 are both blind holes. The upper adjustment hole 31 and the lower adjustment hole 41 are both through holes. In this embodiment, among the multiple upper adjustment holes 31 opened on the upper support member 3, the upper adjustment hole 31 with the longest length is set at the first stepped cross section 6 from the tail end of the bevel, and the upper adjustment hole 31 with the shortest length is set at the second stepped cross section 6 from the head end of the bevel. A matching hole 313 is opened vertically through the first stepped cross section 6 from the head end of the bevel. In this embodiment, the matching hole 313 has the same structure as the fastening hole 311; in other embodiments, the matching hole 313 can also be opened as a stepped through hole.

[0037] The specific usage process of this embodiment is as follows:

[0038] The lower support member 4 is screwed to the base 2 through the lower mounting hole 42;

[0039] The upper support member 3 is placed on the lower support member 4 and the upper support member 3 and the lower support member 4 are moved relative to each other to adjust the mutually fitting portion. Specifically, the less the mutually fitting portion, the higher the height of the adjustment mechanism. In different embodiments, the height gradient level can be increased by adjusting the thickness of each step to complete a preliminary adjustment of the height of the adjustment mechanism.

[0040] Install adjustment members 5 in the corresponding upper adjustment holes 31 and lower adjustment holes 41. Twist the ends of the adjustment members 5 to adjust the spacing between the upper support member 3 and the lower support member 4, completing a secondary precision adjustment. Multiple adjustment members 5 allow the height of the adjustment mechanism to be precisely adjusted within a single step thickness, and also allow the levelness of the upper support member 3 to be adjusted to accommodate installation on a sloped surface. Depending on the installation scenario, the adjustment members 5 can be installed in all or only a portion of the corresponding upper and lower adjustment holes 31 and 41.

[0041] Pour concrete into the upper adjustment hole 31. Under the action of gravity, the concrete fills the upper gap of the adjustment member 5 or flows into the corresponding lower adjustment hole 41. The concrete can be sealed by the base 2.

[0042] The support body 1 and the upper support member 3 are screwed together through the upper mounting hole 32;

[0043] As the concrete solidifies, the base 2, the lower support member 4, the upper support member 3, the support body 1 and the adjusting member 5 are fixed to form a whole to ensure a stable and firm structure.

[0044] This embodiment can better adapt to uneven foundations; the upper support member 3 and the lower support member 4 are completely consistent in structure, which is easy to process, and any two of them can be matched into a pair at will, with low production and maintenance costs; the height of the support body 1 can be adjusted once or twice, so that the height of the seismic isolation support can be adjusted to any height within the allowable range and ensure the levelness; the inclined surface where the upper support member 3 and the lower support member 4 contact each other is connected by a stepped structure to ensure stability, which effectively ensures the stability and firmness of the seismic isolation support.

However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention.
