Stay cable steel strand penetrating and tensioning anchoring device and construction method
The invention relates to the technical field of cable-stayed bridge construction, and discloses a stay cable steel strand penetrating and tensioning anchoring device and a construction method.The stay cable steel strand penetrating and tensioning anchoring device comprises traction systems and a tensioning anchoring system, and the traction systems are installed on the two sides of a bridge tower, are connected with the bridge tower and a main beam and comprise fixed cableways, traction ropes and supporting plates; the tensioning anchoring system is installed on the main beam and comprises an anchorage device, a temporary tool anchor, a tensioning pedestal, a temporary anchor hole and a clamping piece. The traction system drags the steel strand to be conveyed between the main beam and the bridge tower through the supporting plate, and the cable penetrating efficiency and precision can be greatly improved through cooperation with the cable penetrating system. The pilot rod and the pilot cable can effectively avoid the dislocation phenomenon when the steel strand passes through the anchor; the tensioning and anchoring system can accurately and efficiently anchor the steel strand on the main beam, so that the loss of tensioning prestress is reduced, and the stress of the stay cable steel strand is ensured to be uniformly distributed; according to the device and the method, the structure is simple, operation is flexible, safety is high, the automation degree is high, the application range is wide, and various problems existing during strand pulling of the steel strands can be effectively avoided.
本发明涉及斜拉桥施工技术领域，公开了一种斜拉索钢绞线穿束与张拉锚固装置及施工方法，包括牵引系统和张拉锚固系统，牵引系统安装于桥塔两侧，连接桥塔和主梁，包括固定索道、牵引绳及托板；张拉锚固系统安装在主梁上，包括锚具、临时工具锚、张拉台座、临时锚孔、夹片；牵引系统通过托板牵动钢绞线在主梁与桥塔之间进行传送，配合穿索系统可大幅提高穿索效率和精度；先导杆和先导索能有效避免钢绞线穿锚时的错位现象；张拉锚固系统能准确高效将钢绞线锚固在主梁上，减小张拉预应力损失，保证斜拉索钢绞线应力均匀分布；本发明所述装置及方法构造简单、操作灵活、安全性强、自动化程度高、应用范围广，可有效避免钢绞线穿束时存在的多种问题。
