REINFORCEMENT MEMBER GIRDER USING THE SAME AND CONSTRUCTION METHOD THEREOF
The present invention relates to an upper portion reinforcement member which is installed in a lengthwise direction on an upper flange of a girder (10). The reinforcement member comprises: a lower flange (110) in which both ends have a longitudinal section with a gradually widening width going toward the center portion; a web which is formed in a center area of the lower flange (110); and an upper flange (130) which is coupled to the web (120), wherein a spacer is installed at the lower portion of the lower flange. The lower flange of the present invention has a section capable of reasonably resisting bending moment for self weight and use weight due to a geometric structure in which the width of a section gets larger going toward the center portion.
본 발명은 거더(10)의 상부 플랜지(11)에 길이방향으로 설치되는 상부보강부재로서, 양단이 중앙부를 향하여 폭이 커지는 종단면을 갖는 하부플랜지(110); 하부플랜지(110)의 중앙부 영역에 형성된 웹(120);과 웹(120)에 결합되는 상부플랜지(130);를 포함하고 하부플랜지의 하부에 설치되는 스페이서로 구성된다. 본 발명의 하부플랜지는 중앙부로 갈수록 단면의 폭의 커지는 기하학적 구조로 인해 자중 및 사용하중에 대한 휨모멘트에 합리적으로 저항할 수 있는 단면을 갖게 된다.
