[0002] In current building construction, in order to prevent vibration from causing harm to the building, shock-absorbing devices are usually installed in the building. The shock-absorbing devices can greatly reduce the vibration amplitude of the building and change the vibration frequency of the building to prevent vibration from causing damage to the building. Building seismic isolation rubber bearings are commonly used shock-absorbing structures.

A first groove is provided on the side where the two support plates are close to each other, and an energy-absorbing and damping steel plate with a U-shaped cross-section is installed in the first groove.

The vertical plate 4 is provided with a damping and shock-absorbing component for converting the horizontal vibration force exerted on the top support 2 into a vertical force, and performing shock absorption and buffering through the multiple groups of hydraulic dampers 2 30.

[0036] A sealing plate 48 is provided on the surface of the vertical plate 4 , and fixing bolts are provided on the sealing plate 48 .

[0037] The damping and shock absorbing component includes a support plate 1 26 fixedly connected to the surface of the vertical plate 4, a limit rod 25 fixedly connected to the surface of the support plate 1 26, a moving rod 28 slidably connected to the surface of the limit rod 25, a connecting block 2 47 fixedly connected to the surface of the moving rod 28, and a connecting column 1 41 fixedly connected to the surface of the connecting block 2 47;

[0038] The inner wall of the second hydraulic damper 30 is slidably connected to a second piston rod 42. The end of the second piston rod 42 extending out of the second hydraulic damper 30 is fixedly mounted with a first hinge block 43. The surface of the first hinge block 43 is hingedly connected to a second connecting column 38.

[0039] The surface of the vertical plate 4 is connected to the rotating shaft 37 for fixed axis rotation, and the surface of the rotating shaft 37 is connected to the L-shaped rotating plate 36 for fixed axis rotation. The surface of the L-shaped rotating plate 36 is provided with a slide groove 1 40 and a slide groove 2 39.

[0040] The surface of the vertical plate 4 is fixedly connected to two symmetrically arranged support plates 18, and a connecting rod 19 is fixedly connected between the two support plates 18. The surface of the connecting rod 19 is slidably connected to a moving block 1 22 and a moving block 2 24. A shock-absorbing spring 23 is provided between the moving block 1 22 and the moving block 2 24.

[0041] The lower surface of the connecting block 13 is hinged with a hinge plate 35, the end of the hinge plate 35 is hinged to the moving block 22, and the lower surface of the moving block 22 is fixedly installed with a connecting block 3 27, which passes through the moving rod 28 and is fixedly connected to it.

[0042] More specifically, in the embodiments:

[0043] like Figure 1 and Figure 2 As shown, during the construction process, the seismic isolation rubber bearing composed of the bottom support 1, the top support 2 and the seismic isolation rubber layer 3 is installed on the embedded parts. The seismic isolation rubber layer 3 is composed of a rubber shock-absorbing layer 301 and a reinforcing steel plate 302 that are alternated in sequence. Under the elastic action of the rubber, it can well buffer the vertical vibration force suffered by the building. When the building encounters strong winds or earthquakes, the building will shake slightly in the horizontal direction. At this time, the top support 2 will shake slightly relative to the bottom support 1 as the building shakes.

[0044] like Figure 4 、 Figure 5 and Figure 7As shown, when the top support 2 moves horizontally with the shaking of the building, the connecting block 13 will drive the piston rod 15 to move toward the direction of the hydraulic damper 16, and the shock-absorbing spring 14 will be compressed. As the piston rod 15 moves, the piston at the end of the piston rod 15 compresses the hydraulic oil in the cylinder, forcing the hydraulic oil to flow through the damping hole on the piston. In this process, the hydraulic oil generates flow resistance due to viscosity, forming a damping force opposite to the direction of movement, thereby slowing down the movement speed of the piston rod to achieve a buffering effect. With the cooperation of the shock-absorbing spring 14 and the hydraulic damper 16, the vibration force can be preliminarily buffered in the moving direction of the top support 2. The hydraulic damper is a relatively mature existing technology, and its internal structure is not drawn in the diagram.

[0045] As the connecting block 13 moves, under the hinged action of the hinged plate 1 35, the moving block 1 22 will also be driven to move toward the moving block 2 24. At this time, the shock-absorbing spring 23 between the moving block 1 22 and the moving block 2 24 will be compressed. Under the action of the elastic potential energy of the shock-absorbing spring 23, part of the vibration force on the hydraulic damper 16 and the shock-absorbing spring 14 can be shared in the vertical direction of the movement of the top support 2, so as to perform secondary buffering of the vibration force.

[0046] It is worth noting that Figure 8 As shown, as the moving block 1 22 moves toward the moving block 2 24, under the connecting action of the connecting block 3 27, the moving rod 28 will move on the limit rod 25 in the direction away from the support plate 1 26. As the moving rod 28 moves, the connecting block 2 47 will be driven to move synchronously. Taking the two L-shaped rotating plates 36 on the left as an example, as the connecting block 2 47 moves, the connecting column 1 41 will slide in the slide groove 1 40 and push the L-shaped rotating plate 36 on the left to rotate clockwise with the rotating shaft 37 as the axis. As the L-shaped rotating plate 36 rotates, the connecting column 2 38 will slide in the slide groove 2 39 and push the connecting column 2 38 and the piston rod 2 42 to move downward synchronously. Similarly, as the piston rod 2 42 moves downward, a damping force in the vertical direction can be generated in the hydraulic damper 2 30, thereby being able to buffer the horizontal vibration force on the top support 2 for a third time in the vertical direction.

[0047] In summary, the present invention, through the linkage of multiple structures, can buffer the horizontal vibration force received by the top support 2 in the three coordinate directions of front, back, left, right, and vertical through the isolation rubber support composed of the bottom support 1, the top support 2, and the isolation rubber layer 3 when the building encounters strong winds or earthquakes, thereby constructing a three-dimensional shock absorption system, that is, by converting the horizontal vibration energy received by the top support 2 into a vertical force through a mechanical linkage device, and cooperating with the dual buffering mechanism of the hydraulic damper and the spring system, a three-level vibration energy dissipation path is formed. Specifically:

[0048] First, the hydraulic damper 16 realizes the initial horizontal damping, and then the shock-absorbing spring 23 shares the vertical vibration force. Finally, through the rotation of the L-shaped rotating plate 36, the piston rod 2 42 is driven to move downward to activate the hydraulic damper 2 30 in the vertical direction to complete the vertical damping buffering. This design method of the damping combination type seismic isolation rubber bearing breaks the limitation of the traditional rubber bearing's one-way shock absorption, so that the seismic isolation rubber bearing of the present invention can respond to vibration forces in multiple directions at the same time, significantly improving the seismic performance of the building and providing a more comprehensive seismic protection solution for super high-rise buildings.

[0049] Example 2, based on the above example:

[0050] Furthermore, the surface of the moving block 1 22 is fixedly connected with the sensing block 21 , the surface of the vertical plate 4 is fixedly connected with the supporting plate 3 , and the displacement sensor 20 is fixedly mounted on the supporting plate 3 .

[0051] The surface of the vertical plate 4 is fixedly connected to a mounting plate, on which a hydraulic component 29 is provided. The output end of the hydraulic component 29 is fixedly connected to a movable plate 5, which is fixedly connected to multiple groups of hydraulic dampers 2 30. The movable plate 5 passes through multiple piston rods 2 42 and is slidably connected thereto.

[0052] A mounting ring 31 is fixedly connected to the surface of the hydraulic damper 2 30 , a slider 1 33 is fixedly connected to the surface of the mounting ring 31 , and a rectangular notch 1 32 is provided on the surface of the vertical plate 4 for the slider 1 33 to extend and slide.

[0053] A rectangular notch 10 is formed on the surface of the vertical plate 4. A slider 11 is slidably connected to the inner wall of the rectangular notch 10. The end of the slider 11 extending out of the rectangular notch 10 is fixedly connected to the connecting plate 9.

[0054] The surface of the moving block 24 is fixedly connected to the connecting column 3 46, the surface of the connecting column 3 46 is hinged to the hinge plate 2 12, the end of the hinge plate 2 12 is hinged to the connecting plate 9, the surface of the connecting plate 9 is fixedly connected to the rack row 1 8, the surface of the moving plate 5 is fixedly connected to the rack row 2 6, the surface of the vertical plate 4 is fixedly connected to the support plate 4 44, the surface of the support plate 44 is fixedly connected to the rotating rod 45, and the surface of the rotating rod 45 is fixedly connected to the gear 7 meshing with the rack row 1 8 and the rack row 2 6.

[0055] More specifically, in this embodiment:

[0056] like Figure 4 As shown, when horizontal vibration occurs on the top support 2, as the moving block 1 22 moves toward the moving block 2 24, the sensing block 21 will also move toward the direction of the displacement sensor 20. When the displacement sensor 20 senses that the displacement of the sensing block 21 exceeds the critical threshold, it means that the vibration force on the top support 2 is relatively large. In order to better improve the vibration buffering effect of the shock-absorbing spring 2 23 and the hydraulic damper 2 30, the hydraulic component 29 is controlled to start and drive the moving plate 5 to move downward. As the moving plate 5 moves downward, the hydraulic damper 2 30 is driven to move downward synchronously, which will increase the space between the piston at the end of the piston rod 2 42 and the bottom of the hydraulic damper 2 30. The increase in this space will enable the piston at the end of the piston rod 2 42 to have a larger displacement space when vibration occurs, so that the hydraulic damper 2 30 can absorb and disperse the vibration force more effectively.

[0057] like Figure 3 、 Figure 6 and Figure 9 As shown, when the vibration force on the top support 2 is large, the displacement sensor 20 senses that the displacement of the sensing block 21 exceeds the critical threshold, and controls the hydraulic component 29 to drive the movable plate 5 to move downward, while driving the rack row 2 6 to move downward synchronously. As the rack row 2 6 moves downward, under the meshing action of the gear 7 and the rack row 1 8, the connecting plate 9 is driven to move upward. As the connecting plate 9 moves upward, under the hinged action of the hinged plate 2 12, the two movable blocks 2 24 are driven to move in opposite directions, so that the shock-absorbing spring 2 23 between the movable block 1 22 and the movable block 2 24 can be compressed, so that it has higher elastic potential energy in the initial state before the vibration, thereby further improving the buffering and shock-absorbing effect of the shock-absorbing spring 2 23 after the vibration.

[0058] Since the spring will accelerate metal fatigue if it is in a high preload state for a long time, and the hydraulic damper piston will be subjected to high pressure continuously, which may cause the seal to fail prematurely, the present invention monitors the vibration intensity and increases the elastic potential energy of the shock-absorbing spring 23 and the piston displacement space of the hydraulic damper 23 when necessary. This on-demand adjustment mechanism can enable the seismic isolation rubber bearing of the present invention to maintain a low-wear operating state under conventional vibration, leaving high-load conditions for extreme events, thereby improving the service life of the seismic isolation rubber bearing and is worthy of promotion and use.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
