A prestress tensioning operation platform with a protection facility comprises a base and a sliding unit, and is characterized in that the base comprises a horizontal frame and a vertical frame, the horizontal frame is a rectangular steel frame, a plurality of transverse rods are arranged on the rectangular steel frame inwards at equal intervals in the length direction, the vertical frame is a frame formed by erecting one transverse rod and three vertical rods, and the sliding unit is arranged between the transverse rod and the vertical rods. The sliding unit comprises a sliding groove with supporting feet and a transverse rolling groove, and the tensioning device is connected with the sliding unit. The prestress tensioning operation platform with the protection facility has the advantages that the safety of operators in an operation area can be protected if a prestressed tendon fracture phenomenon occurs in a tensioning area, and meanwhile, the operators can open the transparent plastic plate to directly enter the tensioning operation area after the prestress is released.
一种带有防护设施的预应力张拉作业平台，包括底座、滑动单元，其特征在于：所述底座包括水平框架、竖立框架，水平框架为矩形钢框架，矩形钢框架的长度向内等距离设有若干横杆，竖立框架为有一根横杆和三根立杆搭设成的框架，所述滑动单元包括带有支脚的滑槽、横向滚动槽，其中：张拉设备与滑动单元连接。本发明的带有防护设施的预应力张拉作业平台具有如张拉区发生预应力筋断裂现象，可保护在操作区作业人员安全，同时，预应力放张后作业人员可以打开透明塑料板直接进入张拉作业区的优点。
