The present invention relates to a synthetic rahmen bridge capable of reinforcement using a prestress device, and a construction method thereof. According to the present invention, as shown in Fig. 1, an abutment tension set (110) and a pier tension set (120) are arranged in each of a right pier block (310) of an upper part of the abutment and a middle point block (320) of an upper part of the pier among the upper concrete (A) within the spacing of the steel girder (10), and the abutment tension set (110) and the pier tension set (120) are provided in the right pier block (310) and the middle point block (320) in the form shown in Fig. 3, respectively, so that tensile forces may be introduced. Accordingly, it is possible to reduce the negative moment generated in the right pier block (310) and the middle point block (320), and it is possible to reduce excessive deflection and crack generation according to the long-term use of the bridge.
본원발명은 도 1과 같이 강재거더(10) 배치간격 내의 상부콘크리트(A) 중 교대 상부의 우각부블록(310)과 교각 상부의 중간지점블록(320) 각각에 교대긴장세트(110) 및 교각긴장세트(120)가 배치되고, 도 3과 같은 형태로 우각부블록(310) 및 중간지점블록(320)에 각각 교대긴장세트(110)와 교각긴장세트(120)가 구비되어 인장력이 도입될 수 있다. 이로인해 우각부블록(310) 및 중간지점블록(320)에 발생하는 부모멘트를 줄일 수 있으며, 교량의 장기공용에 따른 과다처짐과 균열발생의 저감이 가능해진다.
