PURPOSE: A pre-stressed concrete girder is provided to improve the construction process of a girder bridge by inducing the strong tensile force by mounting a reinforcing part on the girder. CONSTITUTION: A pre-stressed concrete girder comprises a main body(10), a tendon duct(20), a reinforcement unit(30), a stud(40), a first steel reinforcing bar, and a second steel reinforcing bar(60). The main body is made of a reinforced concrete material. The main body is composed of an upper flange(11), a web(12) and a lower flange(13). |
