Novel prestressed steel strand releasing anchor withdrawing device and using method thereof
The invention relates to the technical field of building construction, in particular to a novel prestressed steel strand releasing anchor withdrawing device and a using method thereof. Comprising a hollow anchor withdrawing device body, the anchor withdrawing device body comprises an upper limiting pipe and a lower limiting pipe, the upper limiting pipe and the lower limiting pipe are connected through a reducer pipe, and operation openings are formed in the reducer pipe in the circumferential direction at intervals. The lower limiting pipe is arranged on the working anchorage device in a sleeving mode to wrap the whole steel strand, the steel strand is clamped in batches through the tool clamping pieces, then the working clamping pieces are operated through the operation opening, the whole steel strand can be released, tensioned and withdrawn by installing the jack once, the overall structure is simple, operation is convenient, and installation and disassembly are easy. And a jack does not need to be repeatedly mounted to penetrate through a single steel strand for anchor withdrawing, so that the anchor withdrawing working time is shortened.
本发明涉及建筑施工技术领域，具体是一种新型预应力钢绞线放张退锚器及其使用方法。包括中空的退锚器本体，退锚器本体包括上限位管和下限位管，上限位管和下限位管之间通过变径管相连，变径管上沿周向间隔开设有操作口。下限位管套在工作锚具将整束钢绞线包裹，并通过工具夹片分批将钢绞线夹紧，然后通过操作口对工作夹片进行操作，安装一次千斤顶就可以完成整束钢绞线放张退锚工作，整体结构简单，便于操作，安装拆卸较为容易，不需要重复多次安装千斤顶穿过单根钢绞线进行退锚，从而缩短退锚工作时间。
