Reinforcing structure for negative moment part of girder and the construction method thereof

JUNG SANG WOOK

The present invention relates to a structure for reinforcing a negative moment part of a girder structure and a construction method thereof, wherein the structure for reinforcing a negative moment part of a girder structure comprises: reinforced concrete placed into a lower member of the negative moment part of the girder structure; a cover member covering the reinforced concrete; and a compression means pressurizing and compressing the cover member, thereby preventing separation of the reinforced concrete. Therefore, the structure for reinforcing a negative moment part of a girder structure can increase durability and compression stiffness of the reinforced concrete and improve resistance to the negative moment part and durability of the girder structure to be easily maintained.

본 발명은 거더 구조물의 부모멘트부 하부부재에 타설되는 보강콘크리트와 보강콘크리트를 덮는 덮개부재 및 덮개부재를 압박하여 압축하는 압축수단을 구비하여 보강콘크리트의 들뜸을 방지함으로써, 상기 보강콘크리트의 내구성과 압축강성을 증대시키고, 부모멘트부에 대한 저항력 및 거더 구조물의 내구성을 향상시켜 유지관리를 용이하게 할 수 있는 거더 구조물의 부모멘트부 보강구조 및 그 시공방법에 관한 것이다.
