Shock absorption and isolation structure applied to fabricated beam bridge and method of shock absorption and isolation structure
The invention relates to the field of bridges, discloses a seismic mitigation and isolation structure applied to an assembly type beam bridge, and solves the problems that the impact force generated by a damper is large due to direct impact, the damping coefficient of the damper is fixed, the damper cannot be adjusted according to the field requirement during installation, and the installation cost is low. In order to solve the problem that a plurality of dampers need to be prepared for standby application in the prior art, by arranging a rotating mechanism, a supporting rod can rotate to the outer side of a first push rod when an earthquake occurs, and then the stretching and retracting time of the first push rod can be prolonged, so that the impact force can be reduced; the rotating entering time of the supporting rod is longer than the direct entering time, the generated impact force is reduced, and therefore the purpose of reducing the impact force is achieved.
本发明涉及桥梁领域，公开了一种应用于装配式梁桥的减隔震结构，本发明解决了阻尼器的冲击是直接冲击，其产生的冲击力较大，且阻尼器的阻尼系数是固定的，在安装时不能更加现场的需要进行调整，需要准备多个阻尼器进行备用的问题，通过设置有转动机构，使得在发生地震时支撑杆会旋转运动到第一推杆的外侧，进而第一推杆的伸缩时间会进行延长，以使得冲击力会减小，相对于现有技术，支撑杆旋转进入的时间比直接进入的时间花费更长，产生的冲击力变小，从而达到了减小冲击力的目的。
