Prestressed tendon anchor withdrawing tool structure and anchor withdrawing method
The invention discloses a prestressed tendon anchor withdrawing tool structure and an anchor withdrawing method. The prestressed tendon anchor withdrawing tool structure comprises a positioning frame and a supporting plate. The positioning frame comprises a first side plate and a second side plate which are installed on the two sides of the working anchor plate in a matched mode, and a fixing plate which is fixedly connected with the first side plate and the second side plate and installed on the top edge of the working anchor plate in a matched mode. Positioning steps matched with the two side edges of a working anchor plate are arranged on the lower portions of the opposite faces of the first side plate and the second side plate. The fixing plate is at least partially positioned at the positioning step; the supporting plate is installed on the upper portion of the first side plate and the upper portion of the second side plate, U-shaped grooves are formed in the supporting plate in the opposite direction of the first side plate and the second side plate, one end of each U-shaped groove is open, and the number of the U-shaped grooves is matched with the row number of the prestressed tendons. According to the prestressed tendon anchor withdrawing tool structure and the anchor withdrawing method, original tensioning equipment does not need to be disassembled, stress parts are the edges of the two sides of the working anchor plate during anchor withdrawing and tensioning, and an anchoring unit cannot be damaged.
本发明公开了一种预应力筋退锚工装结构及退锚方法，包括定位框架及支撑板；所述定位框架包括与工作锚板两侧配合安装的第一侧板和第二侧板、及固定连接第一侧板和第二侧板且与工作锚板顶边配合安装的固定板；其中，所述第一侧板和第二侧板相对面的下部设有与工作锚板两侧侧边配合的定位台阶；所述固定板至少部分位于定位台阶处；所述支撑板安装于第一侧板和第二侧板的上部，所述支撑板沿第一侧板和第二侧板相对的方向开设有一端开口的U型槽，所述U型槽的数量与预应力筋的行数相适配。本发明公开的一种预应力筋退锚工装结构及退锚方法，无需对原有的张拉设备进行拆卸，退锚张拉时受力部位为工作锚板的两侧边缘，不会对锚固单元造成损伤。
