RAHMAN BRIDGE AND CONSTRUCTION METHOD THEREOF
A concrete Rahmen bridge according to the present invention comprises: a pair of lower plate units (100) formed after being spaced apart; wall body units (200) each of which is formed at an upper portion of the lower plate units (100); and a slab unit (300) formed such that both edges can be individually coupled to an upper end of the pair of wall body units (200). Here, a hinge coupling unit (400) is installed at a gap between the lower plate units (100) and the wall body units (200) such that the coupling between the lower plate units (100) and the wall body units (200) can have a hinge structure, the hinge coupling unit (400) comprising: a lower portion coupling unit (410) coupled to an upper plane of the lower plate units (100) and having an upper plane curved downwards; and an upper portion coupling unit (420) coupled to a lower plane of the wall body units (200) and having a lower plane corresponding to a curved structure of the upper plane of the lower portion coupling unit (410). Moreover, the lower plate units (100) and the wall body units (200) are coupled in a hinge structure by means of the hinge coupling unit (400). Furthermore, a moment generated at the wall body units (200) and the lower plate units (100) is reduced, thereby reducing the sizes of the wall body units (200) and the lower plate units (100). The hinge coupling unit (400) is installed in a structure like a figure 9, wherein a joint portion of the lower portion coupling unit (410) and the upper portion coupling unit (420) has a round structure.
본 발명인 콘크리트 라멘교는 상호 간격을 두고 형성되는 한 쌍의 저판부(100); 저판부(100)의 상부에 각각 형성되는 벽체부(200); 한 쌍의 벽체부(200)의 상단에 양 가장자리가 각각 결합되도록 형성되는 슬래브부(300);를 포함하되, 저판부(100)와 벽체부(200)의 결합이 힌지구조가 되도록 저판부(100)와 벽체부(200)의 사이 구간에는 힌지결합부(400)가 설치되고, 힌지결합부(400)는 저판부(100)의 상면에 결합되어 상면이 하향으로 만곡진 하부결합부(410); 벽체부(200)의 하면에 결합되어 하부결합부(410)의 상면 만곡구조에 대응하는 하면을 갖는 상부결합부(420);를 포함한다. 이 경우, 힌지결합부(400)에 의해 저판부(100)와 벽체부(200)가 힌지 구조로 결합된다. 따라서 벽체부(200)와 저판부(100)에 발생하는 모멘트를 절감하여 벽체부(200)와 저판부(100) 크기를 줄일 수 있다. 힌지결합부(400)는 도 9과 같은 구조로 설치되는데, 하부결합부(410)와 상부결합부(420)의 접합부가 라운드 구조를 갖는다.
