Easily-reset multistage anti-seismic anchor bolt and bridge
The invention provides an easy-to-reset multistage anti-seismic anchor bolt and a bridge, relates to the field of bridges, aims at solving the problems that a traditional anti-seismic anchor bolt is poor in deformability, single in energy consumption form, difficult to adjust, not easy to reset under the reciprocating earthquake action and the like, optimizes conversion of earthquake energy through a multistage energy consumption assembly, and can be suitable for earthquake scenes with different intensities. The excitation coil can adjust the viscosity of the magnetorheological fluid flowing through the damping hole, and semi-active control over energy consumption and reset effects is achieved. And through the U-shaped inhaul cable and the elastic limiting long rod, the deformation capacity and the limiting function of the anti-seismic anchor bolt are enhanced, and beam falling is prevented.
本发明提供一种易复位多级抗震锚栓及桥梁，涉及桥梁领域，针对传统抗震锚栓变形能力差、耗能形式单一且难以调节、往复地震作用下不易复位等问题，通过多级耗能组件，优化对地震能量的转化，可适用于不同强度的地震场景；励磁线圈能够调整流经阻尼孔的磁流变液粘度，实现耗能和复位作用的半主动控制；通过U型拉索和弹性限位长杆，增强抗震锚栓的变形能力和限位功能，防止落梁。
