For the convenience of understanding, the basic structure of the shock absorbing assembly of the seismically isolated mount assembly of the present application will be described with reference to fig. 1 to 4, wherein it should be noted that the same named components referred to herein are numbered differently in different figures and embodiments, but the basic structure is substantially the same, and therefore, for structural features of the basic components not specifically set forth hereinafter, reference may be made directly to the corresponding description.
In a specific embodiment, the seismic isolation support assembly provided by the invention comprises at least two damping components, wherein the damping components are sequentially arranged along a vertical direction, each damping component comprises a base 11, a support 111 is arranged on the base 11, an elastic part 112 is connected between the bottom of the support 111 and the base 11, the deformation direction of the elastic part 112 is consistent with the vertical direction, a balance body 113 is arranged on the support 111 in a manner of being capable of rotating in a fixed shaft manner, the axis of the balance body 113 extends along the horizontal direction, and the axes of the balance bodies 113 of two adjacent damping components are vertical; the base 11 is further provided with a reaction body 114, the axis of the reaction body 114 on the same base 11 is parallel to the axis of the balance body 113, and when the elastic member 112 is compressed to the limit state, the top end of the balance body 113 on the same base 11 and the top end of the reaction body 114 are located on the same horizontal plane.
Through the cooperative fit of the counterforce body 114 and the balance body 113, the force of the counterforce body 114 acting on the building is offset by utilizing the matching structure of the balance body 113 and the elastic piece 112, when an earthquake with larger intensity occurs, the ground is influenced by earthquake transverse waves to generate horizontal vibration, at the moment, the counterforce body 114 is subjected to the acting force caused by the horizontal vibration of the ground to roll on the base 11 appropriately in a linkage manner with the ground, the horizontal acting force generated by the influence of the earthquake transverse waves is offset, the acting force is prevented from being further transmitted to the building, so that the phenomena of damage and collapse of the building caused by the horizontal forced vibration are effectively avoided, and the integral anti-seismic capacity of the building is improved; meanwhile, the vibration isolation support assembly utilizes rigid structural components such as the reaction body 114 and the balance body 113 as main functional components, the structure is stable and reliable, and the phenomena of component damage and failure caused by high vibration strength after soft components such as a rubber support are adopted in the prior art can be avoided, so that the overall structural strength of the vibration isolation support assembly is effectively ensured.
It should be particularly noted that, in practical application, through the cooperation of the above components, a building adopting the seismic isolation support assembly in the application can keep the horizontal amplitude close to zero all the time in an earthquake with ten-level intensity or even higher intensity, so that the horizontal swing or vibration of the building is effectively inhibited, and the overall seismic performance of the building is remarkably improved.
Furthermore, the base 11 has a limit groove 115 which is aligned and engaged with the balance body 113 and the reaction body 114, respectively, and a reference axis of the limit groove 115 is parallel to an axis of the reaction body 114. When the reaction body 114 rolls due to ground vibration, the limiting groove 115 can control the rolling displacement of the reaction body 114 within a reasonable range, so that the situation that the structure of the vibration isolation support assembly is dislocated or damaged due to the fact that the reaction body 114 rolls beyond a limit position is avoided, and the reliability of the whole structure and the working stability of the vibration isolation support assembly are guaranteed.
It should be noted that, in principle, the above-mentioned reaction body 114 is directly arranged on the top level of the base 11 to achieve the best working effect, and is also the most ideal component structure adapting state.

More specifically, the base 11 is provided with a groove 116, the groove 116 is located below the bracket 111, and the elastic element 112 is a spring whose two ends are respectively welded and fixed with the bottom of the bracket 111 and the groove 116. The groove 116 can reliably limit the working position of the elastic element 112, and avoid the dislocation of the elastic element 112 during actual working; the spring with two ends respectively welded and fixed with the support 111 and the groove 116 is used as the elastic part 112, so that the assembly structure of the elastic part 112 can be effectively simplified, the structural strength of the elastic part is ensured, and the integral structure of the vibration isolation support assembly is simpler and more reliable.
Further, the balance body 113 and the reaction body 114 are both cylindrical. The cylinder has small rolling and rotating resistance, flexible and efficient action in the rolling or rotating process, and can effectively meet the working requirements of the vibration isolation support assembly. In theory, any structure with a radial cross section of a fixed-width curve (the fixed-width curve is a curve with a fixed width similar to a circle; the fixed width is that a circle is placed between two parallel lines and is tangent to the two parallel lines, so that the structure can be used as the basic structural shape of the balance body 113 and the counterforce body 114 no matter how the circle moves, the structure is also in the two parallel lines and is always tangent to the two parallel lines), and specifically, the structure can meet the requirements of smooth rolling and guarantee that a supported object placed above the structure has no vertical displacement, for example, the structure with a shape of a lolo triangle and other lolo shapes in cross section. However, both the balance body 113 and the reaction body 114 are preferably cylindrical in terms of actual part life.

It should be noted that, in order to meet the use requirements under more working conditions, especially under the condition of the limit working condition, in practical application, the number of the upper damping assemblies and the number of the lower damping assemblies may be multiple, and in this case, the upper damping assemblies and the lower damping assemblies should be sequentially arranged at intervals along the vertical direction; in addition, in practical application, the axis of the balance body of the upper shock absorption assembly is not necessarily completely perpendicular to the axis of the balance body of the lower shock absorption assembly, and a certain angle is formed between the axes of the balance body of the upper shock absorption assembly and the axis of the balance body of the lower shock absorption assembly in a horizontal plane.
It should be noted that, in consideration of the cost of the device and the principle of compact structure, in practical application, the matching structure of an upper damping component and a lower damping component with mutually perpendicular balance body axes is the optimal scheme. Of course, in practical application, different damping component matching structures can be adopted as described above, and in principle, the damping component matching structures can meet the practical use requirements of the vibration isolation support assembly.
Please refer to fig. 5 and 6. In the second embodiment of the present application, two shock absorbing assemblies are provided, and both shock absorbing assemblies are configured as shown in fig. 5 and 6.

However, when an earthquake occurs, because the spheres of the balance body 33 and the counter-force body 34 are not collinear, a certain torque is generated in practical application, the existence of the torque generates a rotation trend to the building, and certainly, because the corresponding moment arm of the torque is small, the building cannot be rotated too strongly in practical working conditions, but because the torque is objectively existed, compared with the above-mentioned technical scheme adopting the cylindrical structure, the spherical structure scheme is not an optimal scheme, the existence of the spherical structure scheme is only theoretically achievable, and certainly, the application possibility under the limit working conditions is not excluded, so that a technician can select the spherical component structure scheme according to the difference between the practical working conditions and the use conditions to meet the corresponding technical requirements.
In a specific embodiment, the building provided by the invention comprises a building main body and a vibration isolation support assembly positioned at the bottom of the building main body, wherein the vibration isolation support assembly is specifically the vibration isolation support assembly as described above. The building has good earthquake-resistant performance.
In summary, the seismic isolation support assembly provided by the invention utilizes the cooperative matching of the counterforce body and the balance body, and utilizes the matching structure of the balance body and the elastic piece to offset the force of the counterforce body acting on the building, when an earthquake with larger intensity occurs, the ground is influenced by the transverse wave of the earthquake to generate horizontal vibration, and the counterforce body is subjected to the acting force caused by the horizontal vibration of the ground to appropriately roll on the base in a linkage manner with the ground, so that the horizontal acting force generated by the influence of the transverse wave of the earthquake is offset, and the acting force is prevented from being further transmitted to the building, thereby effectively avoiding the phenomena of damage and collapse of the building caused by the horizontal forced vibration, and improving the integral seismic resistance of the building; meanwhile, the shock insulation support assembly utilizes rigid structural components such as a reaction body and a balance body as main functional components, is stable and reliable in structure, and avoids the phenomena of component damage and failure caused by high vibration strength after soft components such as a rubber support are adopted in the prior art, so that the overall structural strength of the shock insulation support assembly is effectively ensured.
