RAHMEN BRIDGE CONSTRUCTION METHOD USING TEMPORARY SUPPORT MEMBER AND TENDON AND THE RAHMEN BRIDGE THEREWITH
The present invention relates to a rahmen bridge construction method using temporary support members and tension members; and a rahmen bridge constructed using the same which is structurally efficient and economical by installing girders on both abutment units, and effectively controlling a negative bending moment and a positive bending moment generated during a construction process. The temporary support member comprises: a vertical member installed to be perpendicular to a top surface of an end of a girder; and a fixing unit installed in the top surface of the vertical member. As such, an uplifting force is able to be introduced to bend the girder upwards by making the ends of the tension members having a steel rod be tensioned and fixated.
거더를 양 교대부에 설치하고, 시공과정에서 발생하는 휨 부모멘트와 휨 정모멘트를 효과적으로 제어하여 구조적으로 효율적이고 경제적인 가설지주와 인장재를 이용한 라멘교 시공방법 및 이를 이용하여 제작된 라멘교에 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.
