Anchor beam buckling device for continuous arch bridge
The invention belongs to the field of arch bridge construction technology and equipment, and discloses a buckling anchor beam device for a continuous arch bridge, which comprises two groups of buckling anchor beam bases arranged in parallel, two groups of adjusting cable brackets and a coupling beam between the two groups of adjusting cable brackets, the adjusting cable brackets comprise bracket cross beams and bracket inclined struts, and adjusting cable anchoring supports are welded on the bracket cross beams; the adjusting cable anchoring support comprises a welding anchor seat, a clamping pin assembly and an adjusting cable lifting appliance, the steel cables are anchored on the balance cable lifting appliance and can rotate around the clamping pin assembly, and each adjusting cable bracket can anchor one steel cable. The adjusting cable bracket and the adjusting cable anchoring support are introduced on the basis of a traditional buckle anchor beam device, two more groups of steel cables can be anchored, and the two more anchored groups of steel cables are used for temporarily balancing the cantilever state of a new arch rib section in continuous arch bridge left and right two-span cable-stayed buckle hanging symmetrical cantilever splicing construction. The stress of temporary flange fixing and installed segment cable force is reduced, it is guaranteed that the bridge pier and the buckling tower are in a balanced state, and positive significance is achieved for arch rib installation safety and reliability.
本发明属于拱桥施工技术与装备领域，公开了一种用于连续拱桥的扣锚梁装置，包括平行设置的两组扣锚梁基座、两组调节索牛腿及其中间的联梁，调节索牛腿包括牛腿横梁和牛腿斜撑，牛腿横梁上焊接有调节索锚固支座，调节索锚固支座包括焊接锚座、卡销组件和调节索吊具，钢索锚固于平衡索吊具上可绕卡销组件旋转，每组调节索牛腿可锚固一组钢索。本发明在传统扣锚梁装置基础上引入了调节索牛腿和调节索锚固支座，可多锚固两组钢索，多锚固的两组钢索在连续拱桥左右两跨斜拉扣挂对称悬拼施工中用来临时平衡拱肋新节段的悬臂状态，减小了临时固定法兰、已安装节段索力的受力，保证桥墩与扣塔处于平衡状态，对拱肋安装安全、可靠性有积极意义。
