Double-T plate middle section tension external prestress reinforcement device and reinforcement method

The invention provides a double-T plate middle section tension external prestress reinforcement device and reinforcement method. The device comprises a double-T plate to be reinforced, an anchor assembly, a tension assembly, a steering assembly and steel stranded wires. The anchor assembly includes left end anchors, right end anchors and middle anchors, the left end anchor and the right end anchorare arranged on the outer sides of two ends of a panel in the longitudinal direction. The tension assembly includes a left tension member and a right tension member, one end of each of the steel stranded wires is connected to an anchor, the other end is connected to a tension member, the reinforcement of the double-T plate in a load state can be achieved by applying tension force to the steel stranded wires, the bearing ability of the double-T plate is improved, the deformation of the double-T plate is reduced, bending and shearing cracks are avoided, and the good working condition of the double-T plate is ensured. 本
