STEEL-CONCRETE COMPOSITE RAHMEN BRIDGE AND CONSTRUCTION METHOD THEREOF
According to the present invention, a steel composite Rahmen bridge comprises: a pair of wall bodies (100); a protrusion part (110) protruding inward from the upper part of the wall bodies (100); an I-type steel material girder (200) having both ends coupled to the inside of the protrusion part (110); and floor plate concrete (300) placed on the upper part of the steel material girder (200). The steel composite Rahmen bridge comprises: a lower protrusion part (111) having a lower area protruding further toward the inside; and an upper depression part (112) formed inwardly from the upper side of the protrusion part (110) by the lower protrusion part (111). Both ends of the steel material girder (200) are provided with: an upper protrusion part (210) protruding outwardly from an upper region to correspond to the upper depression part (112); and a lower depression part (220) formed in a lower region to correspond to the lower protrusion part (111). Since the protrusion part (110) protruding inwardly from the wall bodies (100) is constructed in an integrated structure when a wall is formed, the rigidity of a right angle part is improved, and thus it is possible to prevent cracks generated in the right angle part. In addition, since a coupling portion coupled to a steel material girder is formed at the inner end of the protrusion part (110), the coupling portion of the steel material girder (200) and the wall bodies (100) is formed near an inflection point region. Therefore, stress generated in the coupling portion can be minimized, and cracks of the coupling portion can be prevented.
본 발명의 강합성라멘교는 한 쌍의 벽체(100); 벽체(100)의 상부에서 내측으로 돌출된 돌출부(110); 돌출부(110)의 내측에 양단부가 결합되는 I형 강재거더(200); 강재거더(200)의 상부에 타설되는 바닥판 콘크리트(300);를 포함하되, 돌출부(110)는 내측을 향하여 하측 영역이 더 돌출된 하측돌출부(111); 하측돌출부(111)에 의해 돌출부(110)의 상측에서 내측으로 형성된 상측함몰부(112);를 포함하고, 강재거더(200)의 양단부는 상측함몰부(112)에 대응하도록 상측 영역에서 외측으로 돌출된 상측돌출부(210); 하측돌출부(111)에 대응하도록 하측 영역에 내측으로 형성된 하측함몰부(220);가 형성된다. 이 경우, 벽체(100)에 내측으로 돌출형성된 돌출부(110)를 벽체 형성시 일체화 구조로 시공하기 때문에 우각부의 강성을 향상시켜 우각부에 발생하는 균열을 방지할 수 있다. 또한, 돌출부(110)의 내측 단부에 강재거더와 결합하는 결합부를 형성하기 때문에 강재거더(200)와 벽체(100)의 결합부를 변곡점 영역 근처에 형성한다. 때문에 결합부에 발생하는 응력을 최소화시키고, 결합부의 균열을 방지할 수 있다.
