RAHMEN BRIDGE AND CONSTRUCTION METHOD THEREOF
A prestressed Rahmen bridge of the present invention comprises: a steel girder (100); a support member (200) which downwardly protrudes from the lower surface of both side edges of the steel girder (100); a tension member (300) which is individually installed on the upper surface of the both side edges of the steel girder (100) in order to reinforce a corner part (B); a concrete wall body (400) which is formed at the lower side of the support member (200) to support the support member (200); and concrete (C) which is placed such that the steel girder (100) and the support member (200) may be buried for forming a deck (1). Here, the tension member (300) is tensed on the side surface of the deck (1) after the deck (1) is formed. As in Figure 1, the tension member (300) is settled after the deck (1) is formed. Therefore, because an outer end part of the tension member (300) is settled on the side surface part of the concrete of the deck (1), compressive force can be applied to a structure system in which the deck (1) and the steel girder (100) are coupled. Consequently, a negative moment generated at the corner part can be reduced.
본 발명의 프리스트레스트 라멘교는 강재거더(100); 강재거더(100)의 양측방 가장자리 하면에서 하측으로 돌출 형성된 받침부재(200); 우각부(B)를 보강하기 위해, 강재거더(100)의 양측방 가장자리 상면에 각각 설치되는 긴장부재(300); 받침부재(200)를 지지하도록 받침부재(200)의 하측에 형성된 콘크리트 벽체(400); 바닥판(1) 형성을 위해, 강재거더(100)와 받침부재(200)가 매립되도록 타설되는 콘크리트(C);를 포함하되, 긴장부재(300)는 바닥판(1)이 형성된 이후에 바닥판(1)의 측면에서 긴장된다. 본원발명은 도 1과 같이 바닥판(1) 형성이후에 긴장부재(300)가 정착된다. 즉, 긴장부재(300)의 외측단부가 바닥판(1) 콘크리트 측면부에서 정착되기 때문에 바닥판(1)과 강재거더(100)가 결합된 구조계에 압축력을 도입할 수 있다. 이로 인해 우각부에 발생하는 부모멘트를 줄일 수 있다.
