Prestress tension anchorage device for reinforcing steel structure
The invention relates to the technical field of tensioning anchorage devices, and discloses a prestressed tensioning anchorage device for reinforcing a steel structure, which comprises a working anchor plate, an anchor backing plate is arranged on one side of the working anchor plate, a plurality of clamping pieces are embedded in the other side of the working anchor plate, a corrugated pipe is arranged on one side of the anchor backing plate, and a spiral bar is sleeved outside the corrugated pipe. The outer wall of the working anchor plate is sleeved with a protective cover, the open end of the protective cover is fixedly connected with a fixing sleeve, a threaded groove is formed in the outer portion of the protective cover, the surface of the threaded groove is in threaded sliding connection with a rotating sleeve, an inflation mechanism is arranged between the rotating sleeve and the fixing sleeve, and a plurality of gas collection cavities are formed in the fixing sleeve at equal intervals in a surrounding mode. The inner wall of each gas collection cavity is connected with a second piston plate in a sealed and sliding mode. By arranging the protective cover, the clamping pieces on the working anchor plate can be protected, the situation that the clamping pieces are corroded and rusted to cause failure of the tensioning anchorage device is avoided, and the service life of the tensioning anchorage device is greatly prolonged.
本发明涉及张拉锚具技术领域，且公开了一种钢结构加固用预应力张拉锚具，包括工作锚板，所述工作锚板一侧设置有锚垫板，且工作锚板另一侧嵌入有多个夹片，所述锚垫板一侧设置有波纹管，且波纹管外部套设有螺旋筋，所述工作锚板外壁套设有防护罩，且防护罩开口端固定连接有固定套，所述防护罩外部设置有螺纹槽，且螺纹槽表面螺纹滑动连接有旋转套，所述旋转套与固定套之间设置有充气机构，且固定套内部等距离环绕设置有多个集气腔，每个所述集气腔内壁均密封滑动连接有活塞板二。本发明通过设置防护罩能够对工作锚板上的夹片进行防护，避免夹片被腐蚀、锈蚀导致张拉锚具失效，大大提升其使用寿命。
