Bridge elastic restraint device
The invention relates to a bridge elastic restraint device. An elastic constraint system or a damping constraint system has the problems of weak bearing capacity, small rigidity, limited service life, high cost and the like. The bridge elastic restraint device is connected between a bridge tower and a main beam and is longitudinally arranged. The bridge elastic restraint device comprises a cylinder sleeve, a hinge base and a piston rod. The piston rod is inserted into the cylinder sleeve in a matched mode to form a piston cylinder sleeve assembly which is longitudinally arranged. The two ends of the piston cylinder sleeve assembly are connected to the top of a bridge tower cross beam and a main beam bottom plate through hinge bases correspondingly. The device is arranged between the tower and the beam and used for controlling the beam end to generate large longitudinal displacement, tower top and beam end displacement can be effectively limited, meanwhile, tower bottom internal force is greatly reduced, the dynamic characteristic of bridge earthquake response is effectively affected, the longitudinal floating vibration mode frequency of the bridge is changed, the anti-seismic capacity of the bridge is improved, and the device has the advantages of being economical, applicable, reliable in structure and the like.
本发明涉及一种桥梁弹性约束器。弹性约束体系或阻尼约束体系存在的承载能力弱、刚度小、使用寿命有限、费用昂贵等问题。本发明的桥梁弹性约束器连接在桥塔和主梁之间并纵向布置，桥梁弹性约束器包括缸套、铰接底座和活塞杆；活塞杆插配到缸套内组成活塞缸套组件，活塞缸套组件纵向设置；活塞缸套组件的两端分别通过铰接底座连接到桥塔横梁的顶部和主梁底板。本发明布置在塔梁之间用以控制梁端产生较大的纵向位移，可以在有效限制塔顶和梁端位移的同时，大大减小塔底内力，有效影响桥梁地震响应的动力特性，改变桥梁的纵飘振型的频率，提高桥梁的抗震能力，具有经济适用、结构可靠等优点。
