| Zusammenfassung: | The present invention relates to a bridge structure using a PC block, comprising an abutment assembly (100) and a pier assembly (200). By concurrently constructing the reinforced concrete (RC) and the precast concrete (PC) block, constructability and structural safety can be secured. In addition, it is possible to increase the tensile strength of a girder by fixing a tension steel bar so that prestress is introduced between a girder and an abutment coping part. In addition, tension steel rods are also fixed in a pier column part and the pier coping part to secure structural rigidity like the Ramen Bridge.
본 발명은 PC블럭을 이용한 교량 구조체에 관한 것으로, RC(현장처리 콘크리트, reinforced concrete)공법과 PC(프리캐스트 블럭, precast concrete block)블럭을 병행 시공함으로써 시공성과 구조적인 안전성을 확보할 수 있고, 또한 거더와 교대코핑부 간에 프리스트레스가 도입되도록 긴장강봉을 정착시켜 거더의 인장강도를 증대시킬 수 있을 뿐만 아니라, 교각기둥부와 교각코핑부에도 긴장강봉을 정착시켜 라멘교와 같은 구조적인 강성을 확보할 수 있는 특징이 있다. |
