Anti-springback steel-strand tensioner
The invention discloses an anti-springback steel-strand tensioner. The steel-strand tensioner comprises a bridge, a prestressed hole formed in the bridge, steel strands penetrating through the prestressed hole, an oil cylinder for dragging the steel strands, a hydraulic pump for driving the oil cylinder to run, and a locking mechanism for blocking the steel strands from springing back. The steel-strand tensioner is artful in improved structure. The steel strands are fixed by the utilization of characteristics of an overrun clutch, and are prevented from springing back, so that the construction quality of the bridge is guaranteed, and the steel-strand tensioner is convenient and safe to operate.
