Middle-span rigid hinge capable of resisting fault dislocation for rigid frame bridge
The invention discloses a midspan rigid hinge capable of resisting fault dislocation for a rigid frame bridge, and relates to the technical field of bridges, a main beam of the rigid frame bridge positioned on one side of a midspan is a first main beam, a main beam of the rigid frame bridge positioned on the other side of the midspan is a second main beam, and the midspan rigid hinge comprises a first support diaphragm, a second support diaphragm and an anti-seismic unit, the anti-seismic unit comprises a first fixed sleeve, a second fixed sleeve, a fixed tubular beam, a movable tubular beam and a safety ring; the first fixing sleeve is arranged in the first supporting diaphragm, the movable pipe beam penetrates through the first fixing sleeve and is in sliding fit with the first fixing sleeve, and the first end of the movable pipe beam is fixedly connected with the first supporting diaphragm; the second fixing sleeve is arranged in the second supporting diaphragm, the fixing tubular beam penetrates through the second fixing sleeve, and the fixing tubular beam is fixedly connected with the second supporting diaphragm; and the fixed tubular beam and the movable tubular beam are fixedly connected with the safety ring respectively. According to the invention, the fault dislocation resistance of the rigid frame bridge is realized.
本发明公开一种刚构桥用抗断层错动的跨中刚性铰，涉及桥梁技术领域，位于跨中一侧的刚构桥的主梁为第一主梁，位于跨中另一侧的刚构桥的主梁为第二主梁，包括第一支撑横隔梁、第二支撑横隔梁和抗震单元，抗震单元包括第一固定套筒、第二固定套筒、固定管梁、移动管梁和保险环；第一固定套筒设置在第一支撑横隔梁内，移动管梁穿过第一固定套筒且移动管梁与第一固定套管滑动配合，移动管梁的第一端与第一支撑横隔梁固连；第二固定套筒设置在第二支撑横隔梁内，固定管梁穿过第二固定套筒，固定管梁与第二支撑横隔梁固连；固定管梁和移动管梁分别与保险环固定连接。本发明实现了刚构桥的抗断层错动。
