Positioning control device for slow bonding prestressed tendons and construction method

The invention discloses a positioning control device for slow bonding prestressed tendons and a construction method, and the construction method comprises the following steps: A, firstly erecting a bracket, erecting a formwork (one side of a beam side formwork), arching, correcting the bottom elevation, and laying common steel bars; b, height loss of prestressed tendons at different positions of the beam is determined according to a deepening drawing, curve coordinate positions of the prestressed tendons are drawn, prestressed steel strands penetrate through the prestressed tendons, clamps are installed and arranged according to position points, the clamps and the prestressed steel strands are fixed, pull rods extend to the top of the beam, clamping buckles and the ends are made of alloy, and the clamping buckles and the ends are made of alloy; and the length of the nail at the end does not exceed the thickness of the end part, namely 10mm. The method has the advantages of being convenient to operate, small i
