Abstract
Description
Technical Field
[0001] The invention relates to the technical field of seismic isolation, in particular to a building seismic isolation support. Background Art
[0002] In earthquake zones, seismic isolation rubber bearings used for houses, bridges or other structures can effectively isolate the transmission of seismic energy to the upper structure when an earthquake occurs, thereby reducing the destruction and damage of earthquake disasters to buildings and bridges. In modern construction projects, seismic isolation bearings are important shock-absorbing devices and are widely used in high-rise buildings, bridges and other key infrastructure to reduce the impact of earthquakes or other external shocks on buildings. However, traditional seismic isolation bearings still have many shortcomings when dealing with complex and changeable load conditions, especially in dealing with high-frequency vibrations and dynamic loads. The service life and performance of the bearings are often limited.
[0003] Traditional seismic isolation bearings usually use ordinary rubber materials to absorb horizontal vibrations and impact forces caused by earthquakes. Although the effect is significant under static or lower-frequency seismic waves, when buildings are subjected to high-frequency vibrations for a long time, the damping performance of ordinary rubber materials is insufficient, resulting in the inability of the bearings to effectively dissipate energy under high-frequency conditions. Summary of the invention

[0010] Preferably, the seismic isolation assembly comprises a support plate 1, and a support rod 1 is fixed inside the support plate 1.
[0011] Preferably, a sliding block 1 which is symmetrical on the left and right slides on the outer wall of the support rod 1, a rotating rod is rotated inside the sliding block 1, a sliding block 2 is fixed on the end of the rotating rod, a support rod 2 slides inside the sliding block 2, the outer wall of the support rod 2 is fixed on the support plate 2, and the outer wall of the support plate 2 is fixed on the outer wall of the connecting plate 2.
[0012] Preferably, the outer wall of the support plate 1 is rotated to one end with the damper 2, and the other end of the damper 2 is rotated on the outer wall of the connecting plate 2.

[0014] Preferably, one end of a spring is fixed to the bottom end of the sliding block, and the other end of the spring is fixed to the inner bottom of the second limiting block.
[0015] Working principle: When the building is subjected to external vibration, the connecting plate 1 initially absorbs the impact force through the elastic deformation of the rubber block 1 and the rubber block 2. At the same time, the high-damping rubber inside the rubber block 2 further enhances the energy absorption effect of the vibration, thereby reducing the direct impact of the vibration on the support. Then, the telescopic rod in the shock-absorbing assembly begins to telescope due to the shaking of the support, driving the hinge block 1 and the connecting rod 1 to produce corresponding rotation and swing through the hinge block 2, further transferring the vibration energy. At this time, the connecting rod 2 works in coordination with the bearing, and the guide rod ensures that the entire device maintains smooth movement during the force-bearing process. The support block transmits the vibration to the damper 1, which absorbs the vibration energy, weakens the impact of the vibration and transmits it to the connecting plate 2. In this process, the auxiliary component starts to work, and the pressure plate squeezes the airbag as the support block moves. The gas is discharged through the air duct. The one-way valve in the air duct ensures that the gas can only be discharged in one direction. The gas is discharged into the sump and the accumulated water is discharged through the drain pipe, which solves the problem of water accumulation in the bearing. At the same time, the seismic isolation component begins to play a role. Support plate one plays a supporting role driven by support rod one. Sliding block one and rotating rod slide and rotate with the shaking of the bearing. Sliding block two and support rod two further alleviate the transmission of building vibration. Support plate two and connecting plate two bear the residual energy of vibration together. In addition, damper two provides the final buffering for the overall vibration and reduces damage to the building by absorbing the remaining vibration energy. During the shaking process, limit block one and the slider limit the shaking amplitude of connecting plate one through the cooperation of spring and limit block two to ensure that the bearing does not shake excessively, thereby extending its service life and improving its seismic resistance.
[0016] The present invention provides a building seismic isolation support having the following beneficial effects:
[0017] 1. The present invention achieves the effect of absorbing the impact force generated by the building on the support while braking the load through the cooperation between the high-damping rubber and the shock-absorbing component, and realizes the dynamic adaptive braking load adjustment function, thereby improving the adaptability of the support under different load conditions, solving the problem of excessive fatigue of the support under high-frequency vibration, and extending the service life of the support.
[0018] 2. The present invention squeezes the airbag through the cooperation between the shock absorbing component and the auxiliary component, and discharges the gas into the water collecting tank through the air guide pipe, thereby achieving the effect of quickly draining the accumulated water in the water collecting tank, and solving the problem of drainage blockage and overflow of traditional supports when the water volume fluctuates.
[0019] 3. The present invention achieves further seismic isolation of the support while limiting the position of the connecting plate 1 through the cooperation between the seismic isolation assembly and the limit block 1, the slider, the limit block 2 and the spring, thereby preventing the support from shaking too much and affecting the service life of the support, further solving the structural fatigue and failure problems caused by excessive shaking of the support during a major earthquake, and ensuring the long-term safety and stability of the support.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] Please see attached Figure 1 - Attachment Figure 4 The embodiment of the present invention provides a building seismic isolation support, including: a connecting plate 1, a rubber block 2 is fixed on the lower surface of which, a rubber block 24 is arranged on the lower surface of the rubber block 2, and a connecting plate 25 is fixed on the lower surface of the rubber block 24; a shock absorbing component 6, which is connected to the connecting plate 1 and is used to absorb the impact force generated by the shaking of the support; an auxiliary component 7, which is linked with the shock absorbing component 6 to discharge the accumulated water inside the support; a seismic isolation component 8, which is connected to the connecting plate 1 and is used to further reduce the damage caused by the shaking of the building to the support; the shock absorbing component 6 includes a telescopic rod 601, the bottom end of the telescopic rod 601 is fixed to the lower surface of the connecting plate 1, and the bottom end of the telescopic rod 601 is fixed with An articulated block 602, a connecting rod 603 is rotatably mounted inside the articulated block 602, an articulated block 604 is rotatably mounted on the outer wall of the connecting rod 603, a connecting rod 605 is fixed to the lower surface of the articulated block 604, a bearing 606 is fixed to the end of the connecting rod 605, a guide rod 607 is fixed inside the bearing 606, a support block 608 is fixed to the outer wall of the guide rod 607, one end of a damper 609 is fixed to the lower surface of the support block 608, and the other end of the damper 609 is fixed to the upper surface of the connecting plate 5, a high damping rubber 3 is arranged inside the rubber block 4, and the upper end of the outer wall of the high damping rubber 3 is arranged inside the connecting plate 1.
[0031] Specifically, the support achieves preliminary vibration absorption through the cooperation of the connecting plate 1 and the rubber block 2, and the rubber block 4 further enhances the seismic isolation effect, wherein the internal high-damping rubber 3 of the rubber block 4 can effectively improve the absorption efficiency of vibration energy, especially showing excellent energy dissipation capacity under high-frequency vibration conditions, and through the close connection between the rubber block 4 and the connecting plate 5, the vibration can be fully alleviated when it is transmitted from the upper structure to the support. The shock absorbing component 6 absorbs the impact force caused by the shaking of the building through the up and down movement of the telescopic rod 601. The connection between the telescopic rod 601 and the hinge block 1 602 makes the component have a certain flexibility, and the interaction between the hinge block 2 604 and the connecting rod 2 605 further ensures the shock absorbing component 6 can operate stably under multi-dimensional vibrations, and the combination of bearings 606 and guide rods 607 ensures that the system remains stable during the shock absorption process. The support block 608 on the outer wall of the guide rod 607 plays a role in supporting the entire structure. At the same time, the damper 1 609 is connected to the support block 608 and the connecting plate 2 5 at both ends, which further reduces the impact and damage of the building shaking on the support. The use of high-damping rubber 3 greatly improves the adaptability of the system under different vibration frequencies, especially can effectively extend the service life of the support under high-frequency vibration. At the same time, the structural design of the present invention can also realize dynamic adaptive adjustment, so that the support can always maintain the best shock absorption effect under different load conditions, greatly improving the seismic performance of the building.
[0032] Please see attached Figure 1 - Attachment Figure 5 A water collecting trough 9 is opened inside the connecting plate 25, and a plurality of drainage pipes 10 are fixed inside the connecting plate 25, and the outer walls of the drainage pipes 10 are fixed inside the water collecting trough 9. The auxiliary component 7 includes a pressing plate 701, and the outer wall of the pressing plate 701 is fixed to the outer wall of the supporting block 608. An air bag 702 is fixed to the lower surface of the pressing plate 701, and the lower surface of the air bag 702 is fixed to the upper surface of the connecting plate 25. A plurality of air guide tubes 703 are fixed to the bottom end of the air bag 702, and the outer walls of the air guide tubes 703 are arranged inside the water collecting trough 9, and a one-way valve 704 is arranged inside the air guide tube 703.
[0033] Specifically, the functionality of the system is further improved through the design of the connecting plate 25. The water collection tank 9 provided inside the water collection tank 9 can effectively collect water accumulation caused by environmental factors or vibration. Multiple drainage pipes 10 are arranged inside the water collection tank 9 to ensure that the accumulated water can be discharged quickly and evenly, thereby avoiding the influence of water retention on the support system. The pressure plate 701 in the auxiliary component 7 is fixed to the support block 608, and the entire auxiliary component 7 is driven to work in conjunction with the swing of the support. The air bag 702 design on the lower surface of the pressure plate 701 can not only play a role in shock absorption and buffering, but also squeeze the air bag 702 to make the gas flow along the air guide tube. The water discharged from the water collecting tank 9 is discharged into the water collecting tank 9, and the bottom end of the air duct 703 is connected to the water collecting tank 9 to ensure the effective transmission of the exhaust gas. The one-way discharge of the airflow is controlled by the one-way valve 704 inside the air duct 703 to avoid the backflow of gas, thereby ensuring the drainage efficiency and the long-term working stability of the airbag 702. The beneficial effect of this design is that the combination of the water collecting tank 9 and the drainage pipe 10 can solve the structural damage caused by long-term water accumulation in the building support. At the same time, the airbag 702 cooperates with the air duct 703 to realize the automatic drainage function, which not only avoids the blockage problem that is easy to occur in the traditional drainage system, but also ensures the reliability of the support system in a high humidity environment.
[0034] Please see attached Figure 6 - Attachment Figure 8 The seismic isolation assembly 8 includes a support plate 801, a support rod 802 is fixed inside the support plate 801, a sliding block 803 is symmetrically slidably provided on the outer wall of the support rod 802, a rotating rod 804 is rotated inside the sliding block 803, a sliding block 805 is fixed at the end of the rotating rod 804, a support rod 806 is slidably provided inside the sliding block 805, the outer wall of the support rod 806 is fixed to the support plate 807, and the outer wall of the support plate 807 is fixed to the connecting plate 5. The outer wall of the support plate 801 is rotated to one end with the damper 808, and the other end of the damper 808 is rotated on the outer wall of the connecting plate 5. The outer wall of the rubber block 2 is fixed with a limiting block 11, and a slider 12 is fixed on the lower surface of the limiting block 11. The outer wall of the rubber block 4 is fixed with a limiting block 13. The outer wall of the slider 12 slides inside the limiting block 13. The bottom end of the slider 12 is fixed with one end of a spring 14, and the other end of the spring 14 is fixed to the inner bottom of the limiting block 13.
[0035] Specifically, the outer wall of the support rod 1 802 is slidably installed with a left-right symmetrical sliding block 1 803. This symmetrical design ensures that the system can maintain balance when subjected to external vibrations. The sliding block 1 803 realizes a flexible rotation connection through the rotating rod 804 inside it. The end of the rotating rod 804 is connected to the sliding block 2 805, so that the sliding block 2 805 can slide freely with the vibration, and the support rod 2 806 inside the sliding block 2 805 further enhances the stability of the system. The support rod 2 806 is fixedly connected to the support plate 2 807 through its outer wall, and the support plate 2 807 is tightly combined with the outer wall of the connecting plate 2 5. This design can transfer the vibration energy from the upper structure to the seismic isolation system when the building vibrates, and effectively disperse the vibration force through the cooperation of various components. At the same time, the outer wall of the support plate 1 801 is also rotatably connected to the damper 2 808, and the other end of the damper 2 808 is connected to the connecting plate The outer wall of the rubber block 25 is connected, and through the buffering effect of the damper, most of the vibration energy can be effectively absorbed, and the impact of the vibration on the support is further reduced. In addition, the design of the limit block 11 and the slider 12 on the outer wall of the rubber block 2, combined with the limit block 2 13 on the outer wall of the rubber block 24, can limit the shaking range of the support by sliding the slider 12 in the limit block 2 13 to avoid excessive shaking of the support. This limiting system provides an additional buffering function through the spring 14 at the bottom. One end of the spring 14 is fixed to the bottom end of the slider 12, and the other end is fixed to the inner bottom of the limit block 2 13. When shaking occurs, the spring 14 can absorb part of the vibration energy and restore the initial position of the slider 12, thereby ensuring that the system can still remain stable under multiple vibrations. Through the above-mentioned structural coordination, the present invention realizes multiple dispersion and buffering of vibration energy, and further improves the reliability of the seismic isolation system.
