Limiting curved beam during bridge earthquake
The invention relates to a limiting curved beam during bridge earthquake, and belongs to the technical field of bridge energy dissipation. The limiting curved beam comprises an operation and maintenance module and an earthquake limiting module. The operation and maintenance module comprises a suspension assembly, a boosting plug pin, a follow-up core block and a guide sliding way. The suspension assembly is used for being connected with a main beam; the suspension assembly is in contact connection with the follow-up core block through the boosting plug pin, the follow-up core block is in sliding connection with the guide sliding way, the earthquake limiting module comprises a variable cross-section curved beam arranged in the transverse bridge direction, one end of the variable cross-section curved beam is connected with the follow-up core block, the other end of the variable cross-section curved beam is connected with a connecting beam bracket, and the connecting beam bracket is connected with the main beam. Compared with the prior art, the sliding behavior stability of the limiting curved beam in the normal use state of a bridge structure is doubly guaranteed through two force transmission paths, and the controllability of the operation period is higher; curved beams which are symmetrically arranged in a crossed mode can deform to the maximum degree in the transverse direction of the bridge and also have the energy dissipation and limiting effects during earthquake.
本发明涉及一种桥梁震时限位曲梁，属于桥梁耗能技术领域。桥梁震时限位曲梁包括运维模块与震时限位模块，所述运维模块包括悬吊组件、助推插销、随动芯块和导向滑道，所述悬吊组件用于连接主梁，所述悬吊组件通过助推插销与随动芯块接触连接，所述随动芯块与导向滑道滑动连接，所述震时限位模块包括沿横桥向设置的变截面曲梁，所述变截面曲梁一端与随动芯块连接，另一端与连梁托架连接，所述连梁托架用于与主梁连接。与现有技术相比，本发明通过两道传力路径双重保证该装置在桥梁结构正常使用状态下的滑动行为稳定，运营期可控性更强；对称交叉布置的曲梁可沿横桥向最大程度发生变形，兼起震时耗能和限位作用。
