BRIDGE CONSTRUCTION METHOD FOR SUPPORT OVERTURNING AND HORIZONTAL DISPLACEMENT CONTROL
The present invention relates to a bridge construction method capable of controlling horizontal displacement and preventing support from overturning, wherein the bridge construction method enables economical and easy construction of a temporary structure by controlling the horizontal displacement and preventing overturning on the support in the temporary structure of a girder using a steel pipe such as a truss steel girder. The bridge construction method includes: (a) a step of prefabricating the girder for a bridge, wherein barrier concrete for preventing overturning is formed in order for a part of both ends to be exposed, in a factory and extending an overturning prevention rod from the upper surface of the support of a bridge lower structure to the upper side; (b) a step of preventing the overturning on the temporary structure of the girder for a bridge by lifting the girder for a bridge and connecting the barrier concrete for preventing the overturning to the overturning prevention rod; and (c) a step of controlling the horizontal displacement in the transverse and longitudinal directions of the girder for a bridge at the support by supporting the partially exposed both ends of the girder for a bridge on the inner side of both brackets of a support device for controlling a horizontal force, which is installed on the upper side of a permanent bridge support of the bridge lower structure.
트러스 강재거더와 같은 강관을 이용한 거더의 가설 중 지점부에 있어 수평변위 제어 및 전도방지가 가능하여 보다 경제적이고 용이한 가설시공이 가능한 지점부 전도방지 및 수평변위 제어가 가능한 교량시공방법에 관한 것으로서, 상기 교량시공방법은 (a) 공장에서 양 단부가 일부 노출되도록 전도방지용 격벽콘크리트를 형성시킨 교량용 거더를 미리 제작하고, 교량하부구조물의 지점부 상면으로부터 전도방지봉이 상방으로 연장되도록 하는 단계; (b) 상기 교량용 거더를 인양하여 전도방지용 격벽콘크리트를 전도방지봉에 결합시켜 교량용 거더 가설 중 전도를 방지하는 단계; 및 (c) 상기 교량용 거더의 일부 노출된 양 단부를 교량하부구조물의 영구교량받침상면에 설치된 수평력제어용 받침장치의 양 브라켓 내측에 지지되도록 하여 지점부에서 교량용 거더의 횡방향 및 종방향 수평변위가 제어되도록 하는 단계;를 포함한다.
