GIRDER BRIDGE CONSTRUCTION METHOD USING TEMPORARY SUPPORT MEMBER AND TENDON AND THE GIRDER BRIDGE THEREWITH
The present invention relates to a girder bridge construction method using a temporary support post and a tension member and a girder bridge constructed using the same which install a girder on both abutments and a bridge post and control a negative bending moment and a positive bending moment created during a construction process to provide structural efficiency and economic efficiency. The temporary support post comprises: a vertical member vertically installed on an upper surface of an end of a girder; and a fixing device installed on an upper end of the vertical member. One end of a tension member including a steel bar is tensioned and then fixed on the fixing device to introduce an upward force to curve the girder upwards.
거더를 양 교대부 및 교각에 설치하고, 시공과정에서 발생하는 휨 부모멘트와 휨 정모멘트를 효과적으로 제어하여 구조적으로 효율적이고 경제적인 가설지주와 인장재를 이용한 거더교 시공방법 및 이를 이용하여 제작된 거더교에 관한 것으로서, 상기 가설지주는 거더의 단부 상면에 수직으로 설치된 수직재; 및 상기 수직재 상단에 설치된 정착장치를 포함하도록 구성하여, 강봉을 포함하는 인장재의 일단부가 상기 정작장치에 긴장 후 정착되도록 함으로서 거더를 상방으로 만곡되도록 상향력이 도입된다.
