PRESTRESSED CONCRETE GIRDER AND BRIDGE CONSTRUCTION METHOD THEREOF
A prestressed concrete girder of the present invention comprises: an upper tension member (210) which is buried in an upper region of a girder (100) and is installed in a longitudinal direction of the girder (100); a fixation steel beam (300) embedded in the upper region of the girder (100) to fix the upper tension member (210); a lower tension member (220) installed in a lower region of the girder (100); and a hollow member (400) embedded in the girder (100). The girder (100) is a segmented girder including a central segment portion (110), one segment portion (120), and the other segment portion (130). The fixation steel beam (300) is installed on the central segment portion (110), the one segment portion (120), and the other segment portion (130) in common. The present invention is the prestressed concrete girder, in which the central segment portion (110), the one segment portion (120), and the other segment portion (130) are manufactured in a segmented state and coupled, as shown in FIG. 1 wherein the fixation steel beam (300) is coupled to an upper side of the central segment portion (110) as shown in FIG. 4. According to the present invention, in the upper part of a girder, embedded is an upper tension member which can introduce compressive force to a lower region of the girder after coupling of a bottom plate and the girder.
본 발명의 프리스트레스트 콘크리트 거더는 거더(100)의 상측 영역에 매립되되, 거더(100)의 길이방향을 따라 설치되는 상측 인장부재(210); 상측 인장부재(210)를 정착시키기 위해, 거더(100)에 상측 영역에 매립되는 정착강형(300); 거더(100)의 하측 영역에 설치되는 하측 인장부재(220); 거더(100)의 내측에 매립되는 중공부재(400);를 포함하고, 거더(100)는 중앙분절부(110); 일측분절부(120); 타측분절부(130);를 포함하는 분절거더이고, 정착강형(300)은 중앙분절부(110), 일측분절부(120), 타측분절부(130)에 공통으로 설치된다. 본 발명은 도 1과 같이 중앙분절부(110), 일측분절부(120), 타측분절부(130)가 각각 분절상태로 제작되고, 결합되는 프리스트레스트 콘크리트 거더이다. 이때 정착강형(300)은 중앙분절부(110)의 상측에 도 4와 같이 결합된다.
