Prestress reinforcing system for reinforcing concrete beam through CFRP sheets
The invention discloses a prestress reinforcing system for reinforcing a concrete beam through CFRP sheets, and belongs to the technical field of concrete beam reinforcing systems. The end fixing mechanism comprises a fixing plate, the fixing plate is used for being fixed to the end of the concrete beam, the sliding tensioning locking mechanism comprises lifting screws arranged side by side, one ends of the lifting screws are fixed to the fixing plate, the lifting screws are sleeved with sliding rings, and the sliding rings are arranged on the fixing plate. Lifting control nuts are arranged on the lifting screws on the lower portions of the sliding rings, translation screws fixedly connected with the sliding rings are arranged on the sliding rings, one ends of the translation screws are fixed to the sliding rings, sliding sleeves connected with the translation screws in a sleeving mode are arranged on the translation screws, and translation control nuts are arranged at the other ends of the translation screws. A columnar barrel is arranged between the two sliding sleeves, and connecting shafts are arranged at the two ends of the columnar barrel. The technical scheme is used for solving the problem that the recovery work is difficult after the prestress of the CFRP sheet is lost.
本发明公开了一种用CFRP片材加固混凝土梁的预应力加固系统，属于混凝土梁加固系统技术领域。所述端部固定机构包括固定板，所述固定板用于固定于混凝土梁的端部上，所述滑动张拉锁紧机构包括并排设置的升降螺杆，所述升降螺杆的一端固定于固定板上，所述升降螺杆上均套接设有滑环，所述滑环下部的升降螺杆上均设有升降控制螺母，所述滑环上均设有与之固定连接的平移螺杆，所述平移螺杆的一端固定于滑环上，所述平移螺杆上设有与之套接设置的滑动套筒，所述平移螺杆的另一端上设有平移控制螺母，两个所述滑动套筒之间设有柱状筒，所述柱状筒的两端设有连接轴。本技术方案用以解决CFRP片材出现预应力损失后的恢复工作困难的问题。
