Modular tensioning tool for stay cable and tensioning method of modular tensioning tool
The invention discloses a modular tensioning tool for a stay cable and a tensioning method of the modular tensioning tool, the stay cable comprises a cable body, the tensioning end of the cable body is connected to an existing lug plate through an anchor head, and the tensioning tool comprises a reaction frame detachably connected to the existing lug plate; the force exerting frame is detachably connected to the cable body and abuts against the anchor head in an attached mode. One end of the connecting rod is detachably connected with the reaction frame, the other end of the connecting rod extends towards the force applying frame, a through hole for the connecting rod to penetrate through is formed in the force applying frame, and the connecting rod penetrates through the through hole and forms a first extending section; and the jack is used for pushing the force exerting frame to drive the cable body to be tensioned, the jack is detachably connected to the first extending section, the output end of the jack abuts against the force exerting frame, and prestress tensioning under the narrow working condition is facilitated by arranging the tensioning tool.
本发明公开了一种用于斜拉索的模块化张拉工装及其张拉方法，所述斜拉索包括索体，所述索体的张拉端通过锚头连接至既有耳板，所述张拉工装包括：反力架，所述反力架可拆卸地连接在既有耳板上；着力架，所述着力架可拆卸地连接在所述索体上并贴抵至所述锚头；连接杆，所述连接杆的一端与所述反力架可拆卸连接，另一端向所述着力架延伸，所述着力架上开始有供所述连接杆穿过的通孔，所述连接杆穿过所述通孔并形成有第一延伸段；用于顶推所述着力架以带动所述索体张拉的千斤顶，所述千斤顶可拆卸地连接在所述第一延伸段上、且所述千斤顶的输出端抵顶至所述着力架，通过设置所述张拉工装便于狭窄工况下的预应力张拉。
