METHOD OF CONSTRUCTION FOR BUILDING PSC(PRESTRESSED CONCRETE) GIRDER BRIDGE AND CONSTRUCTION METHOD THEREOF

摘要

A prestressed concrete girder bridge and a construction method thereof are provided to prevent safety accident as strain task of a tendon is unnecessary and to facilitate construction by simplifying the coupling method of a girder and an abutment. A prestressed concrete girder bridge comprises an abutment(100), a girder(200), and a fastening unit. A first steel material(110) is formed on the top of the abutment. The girder comprises a tendon(210) and a second steel material(220). The tendon is placed along the longitudinal direction of the girder. The tendon introduces the tension into the girder. The second steel material is formed at the end of both sides of the girder. The fastening unit binds the first steel material and the second steel material. The fastening unit is made of a bolt and a nut. The girder comprises an upper flange(202), a lower flange(204) and a web(206). The upper flange is formed in the longitudinal direction of the girder. The lower flange is formed to be parallel at constants intervals. The web connects the upper flange and the lower flange.
