Steel composite PSC corrugated steel plate U-shaped girder simple bridge and continuous bridge
A U-shaped girder (20) includes a concrete lower flange (201), a pair of concrete upper flanges (202), and a pair of corrugated steel plate web (203) connected to two sides of the concrete lower flange (201) and the pair of concrete upper flanges (202). A first inner tensile PS steel wire filling pier and anchor zones (22a) are arranged below the two ends of the U-shaped girder (20). A second inner tensile PS steel wire filling pier and anchor zones (22b), deviating from the two ends of the U-shaped girder (20), are arranged above the concrete lower flange (201). First and second outer tensile PS steel wire filling piers and anchor zones (24, 25) are arranged successively from top to bottom along the two ends of the U-shaped girder (20). First and second inner tensile PS steel wires (W1, W2) are stretched by a bridge manufacturer. First and second outer tensile PS steel wires (W1, W2) are arranged on a bridge stand (10) of the U-shaped girder (20), and are stretched on a prefabricated bridge panel (23) after casting of the bridge panel. Through application of the invention, lift force can be transmitted above in a more uniform and more effective manner when prestress is introduced.
