Cable-stayed bridge deck tensioning device and construction method thereof
The invention relates to a cable-stayed bridge deck tensioning device and a construction method thereof, and belongs to the technical field of bridge stay cable construction. The device comprises a reaction frame assembly and force exerting frames, wherein the force exerting frames are symmetrically arranged on the two sides of a cable body and fixedly connected with lug plates respectively, and the lug plates are arranged on the two sides of a cable guide pipe; a reverse jacking pipe assembly is arranged on the surface of the cable body, one end of the reverse jacking pipe assembly abuts against an anchor cup, the other end is provided with the reaction frame assembly, the reaction frame assembly is arranged on the cable body in a sleeving mode, the reaction frame assembly is provided with jacks, the jacks are symmetrically arranged on the two sides of the cable body, connecting rods are arranged between the force exerting frames and the jacks in a penetrating mode respectively, one end of each connecting rod is fixedly connected with the force exerting frame, and the other end of each connecting rod is fixedly connected with the corresponding jack. According to the invention, thestay cable can be tensioned on the bridge deck, the structure is simple, the operation is convenient and fast, the situation that the stay cable cannot be tensioned due to insufficient space in the box is avoided, the operation environment is safe, and equipment carrying is convenient.
本发明涉及一种拉索桥面张拉装置及其施工方法，属于桥梁拉索施工技术领域。包括反力架组件和着力架，所述着力架对称设于索体两侧，所述着力架分别与耳板固定连接，所述耳板设于索导管两侧；所述索体表面设有反顶管组件，所述反顶管组件一端抵住锚杯，另一端设有反力架组件，所述反力架组件套于索体上，所述反力架组件上设有千斤顶，所述千斤顶对称设于索体两侧，所述着力架与千斤顶之间分别穿设连接杆，所述连接杆一端与着力架固定连接，所述连接杆另一端与千斤顶固定连接。本申请可实现拉索在桥面进行张拉，不仅结构简单，操作便捷，避免了箱内空间不足而无法实现拉索张拉，而且作业环境安全，便于设备搬运。
