Abstract

본 발명은 교량의 아이빔 보강방법 및 보강된 빔 구조에 관한 것으로, 기존 아이빔의 웨브부(3)와 상부 및 하부플랜지(2a,2b) 표면이 녹이 슨 부위를 벗겨내고 아이빔(4)의 길이방향과 세로방향으로 일정한 간격(d)을 유지하면서 보울트구멍이 형성되어지고, 이 보울트구멍이 대응되는 보울트구멍이 형성된 강철판이나 앵글이 보울트(5)를 매개로 체결되며, 이렇게 체결된 상태에 상부 및 하부플랜지(2a,2b)와 웨브부(3) 사이 공간에 모울타르나 콘크리트가 타설된 구조로 되어, 기존의 부재와 역학적으로 일체가되어 가중된 하중을 효과적으로 지지하여 주도록 되어 있다.The present invention relates to a method for reinforcing an i-beam of a bridge and a reinforced beam structure. The bolt hole is formed while maintaining a constant distance (d) in the vertical direction, and the steel plate or angle on which the bolt hole is formed is fastened through the bolt (5). A structure in which mortar or concrete is poured into the space between the lower flanges 2a and 2b and the web part 3 is integrated with the existing member to support the weighted load effectively.
