Tensioning device for insufficient reserved length of steel strand and application method thereof
The invention discloses a tensioning device for insufficient reserved length of a steel strand and an application method thereof. The tensioning device comprises a working anchor, a jack, a tool anchor, a connecting component, a dowel bar, a counter-force support and a limiting part. Steel base plates are arranged on the two sides of the working anchor respectively, and the two ends of the connecting component are detachably connected with the tool anchor and the dowel bar respectively. The counter-force support is sleeved outside the connecting component, the inner end of the counter-force support is supported on the steel base plate on the outer side of the working anchor, the jack is concentrically arranged on the outer side of the counter-force support, and the dowel bar penetrates through the jack and then is locked through the limiting part. When the jack works, tensile force is generated on the dowel bar, the tool anchor can pull the steel strand outwards, meanwhile, supportinglegs of the counter-force support abut against the steel base plate on the inner side of the tool anchor, tensioning operation is safe and reliable, and operation is easy. According to the tensioningdevice for insufficient reserved length of the steel strand and the application method thereof, tensioning of the steel strand is achieved in the mode that the steel strand is pulled outwards, the requirement for the reserved length of the steel strand is reduced, when the reserved length of the steel strand is insufficient, anchor cable construction does not need to be conducted again, and the production cost and the construction cost are low.
本发明公开了一种用于钢绞线预留长度不足的张拉装置及其应用方法，装置包括工作锚、千斤顶、工具锚、连接构件、传力杆、反力支架和限位件，工作锚的两侧分别设置钢垫板，连接构件的两端分别可拆卸连接工具锚和传力杆，反力支架套于连接构件外，内端支撑于工作锚外侧的钢垫板上，千斤顶同心置于反力支架的外侧，传力杆穿过千斤顶后通过限位件锁紧。千斤顶工作时将对传力杆产生拉力可使工具锚将钢绞线往外拉，同时反力支座的支腿顶住工具锚内侧的钢垫板，张拉操作安全可靠且操作简单。本装置采用将钢绞线往外拉的方式实现其张拉，缩短了对钢绞线预留长度的要求，当出现钢绞线预留长度不足时，无需重新进行锚索施工，生产成本及施工成本低。
