Variable-friction-coefficient sliding shock isolation device with limiting function
The invention belongs to the technical field of seismic isolation, and discloses a variable friction coefficient sliding seismic isolation device with a limiting function, which comprises a ring beam, a sliding area is arranged at the bottom of the ring beam, the sliding area comprises a first ceramsite layer, and the first ceramsite layer is arranged at the bottom of the ring beam; the second ceramsite layers are symmetrically arranged on the two sides of the first ceramsite layer, and the particle size of the second ceramsite layers is smaller than that of the first ceramsite layer; the third ceramsite layers are symmetrically arranged on the two sides of the second ceramsite layer; the rubber pier is arranged on the outer side of the third ceramsite layer and used for limiting sliding displacement of the ring beam, the oil tank is arranged on the ring beam, and engine oil in the oil tank is sprayed on ceramsite to change the friction coefficient of the ceramsite; according to the scheme, the change of the friction coefficient is achieved by arranging the ceramsite with the particle size from large to small, and the problems that in the prior art, the ring beam is difficult to slide due to the fact that the friction coefficient of materials is too large, the shock isolation effect is weak, the ring beam sliding displacement is too large due to the small friction coefficient, and a shock isolation device is not limited are solved.
本发明属于隔震技术领域，公开了一种带限位的变摩擦系数滑移隔震装置，包括圈梁，圈梁的底部设有滑移区，滑移区包括第一陶粒层，第一陶粒层设于圈梁的底部；第二陶粒层，第二陶粒层对称设于第一陶粒层的两侧，第二陶粒层的粒径小于第一陶粒层；第三陶粒层，第三陶粒层对称设于第二陶粒层的两侧；还包括设于第三陶粒层外侧的橡胶墩，橡胶墩用于限制圈梁的滑移位移，还包括设于圈梁上的油罐，油罐中机油淋在陶粒上改变其摩擦系数；本方案通过设置粒径由大到小的陶粒以实现摩擦系数的变化，本发明解决了现有技术中材料摩擦系数过大导致圈梁起滑困难，隔震效果弱，摩擦系数小导致圈梁滑移位移过大，以及隔震装置无限位问题。
