Shock absorption and isolation support with multi-stage anti-seismic performance
The invention relates to a bridge shock-absorbing support, in particular to a shock-absorbing and shock-isolating support with multi-stage anti-seismic performance, and aims to solve the problems that an existing shock-absorbing and shock-isolating support is relatively single in buffering and shock-absorbing performance and relatively difficult to repair after being damaged, an upper support plate is fixed at the upper part of a check ring, and a lower support plate is fixed at the lower part of a central pressure-bearing block; the check ring is connected with the central pressure-bearing block through a plurality of combined components; the combined component comprises a steel column, a steel sleeve, an instability sensitive component and a spring; the left end of the steel column is fixedly connected or hinged to the inner side wall of the check ring, the right end of the steel sleeve is fixedly connected or hinged to the outer side wall of the center pressure bearing block, the section of the steel column is in step-shaped shrinkage distribution from left to right, the right end of the steel column is inserted into a cavity in the left end of the steel sleeve, and the spring is arranged in the cavity of the steel sleeve. The left end of the instability sensitive component is hinged to the middle shoulder of the steel column, the right end of the instability sensitive component is hinged to the outer wall of the left end of the steel sleeve, and energy input by an earthquake can be dissipated.
本发明涉及桥梁减震支座，具体涉及一种具备多级抗震性能的减隔震支座，为了解决现有的减隔震支座存在缓冲与减震的性能较为单一，破坏后修复较为困难的问题，上支座板固定在挡圈的上部，下支座板固定在中心承压块的下部，挡圈的与中心承压块通过多个组合构件连接；组合构件包括钢柱、钢套筒、失稳敏感型构件和弹簧；钢柱左端与挡圈的内侧壁固接或铰接，钢套筒的右端中心承压块的外侧壁固接或铰接，钢柱的截面由左至右为阶梯状收缩分布，钢柱的右端插入设置钢套筒的左端空腔内，弹簧设置在钢套筒的空腔内，失稳敏感型构件的左端与钢柱的中部台肩处铰接，失稳敏感型构件的右端与钢套筒的左端外壁处铰接，本方案能够将地震输入的能量耗散。
