REUSABLE DEVICE FOR PRESTRESSED TENSION OF RAILWAY CONTINUOUS CAST-IN-PLACE BEAM
Disclosed is a reusable device for prestressed tension of a railway continuous cast-in-place beam. An outer side of a trench body of a stainless steel tension trench is coated with a demolding layer, a vertical prestressed tendon vertically penetrates a centre of the bottom of the trench body, and an anchor bearing plate of the vertical prestressed tendon is fixed to the bottom of the trench body through a finish-rolled thread tension nut. The outer side of the trench body of the stainless steel welded tension trench used in the present invention is coated with the demolding layer, and the anchor bearing plate of the vertical prestressed tendon is fixed to the bottom of the trench body, and manual demolding may be performed after concrete is finally set, such that the device is reusable. Therefore, the device may be used to effectively guarantee a geometric size and a quality of the tension trench, and has a simple structure, is convenient to use and saves labour and materials.
