STEEL COMPOSITE GIRDER FOR PREVENTING DEFORMATION OF INNER HOLLOWNESS AND COMPACT PLACING OF INFILLED CONCRETE
The present invention relates to a steel composite girder with a buoyancy prevention member, and more specifically, to a steel composite girder for preventing deformation of an inner hollow material and enabling the compact placing of infilled concrete, wherein a bearing stress resistance block is installed at the lower surface of the buoyancy prevention member to resist against bearing stress generated by buoyancy, thereby preventing deformation of locations caused by an inner hollow material digging into the buoyancy prevention member. Furthermore, when the infilled concrete is placed, the placing of the infilled concrete may be checked while the infilled concrete is smoothly and compactly filled. In addition, the longitudinal cutting unit of the inner hollow material is matched with the locations which are spliced on site to form a partition unit, thereby preventing an additional installation work of the inner hollow material on site. Additionally, harmful deformations which may be caused when the inner hollow material is connected to the middle are prevented. To this end, the present invention comprises: a U-shaped steel girder; an angle frame; a buoyancy prevention member; an inner hollow material; first and second lower surface bearing stress resistance blocks; and infilled concrete.
부력방지부재를 구비한 강합성 거더에 있어서, 지압응력 저항용 블록을 부력방지부재의 하면에 설치함으로써 부력에 의해 발생하는 지압응력에 저항하여 내부중공재의 부력방지부재에 파고드는 현상 등에 의한 위치 변형이 발생하는 것을 방지할 수 있으며, 또한, 내부충전 콘크리트의 타설시, 내부충전 콘크리트의 타설을 확인하면서 내부충전 콘크리트를 원활하고 밀실하게 충전할 수 있고, 또한, 내부중공재의 종방향 절단부를 현장이음 위치와 일치시켜 격벽부를 형성함으로써 현장에서 내부중공재의 추가 설치작업이 필요 없고, 내부중공재의 중간 연결시 발생할 수 있는 유해한 변형을 방지할 수 있는, 내부중공재의 변형 방지와 내부충전 콘크리트의 밀실 타설이 가능한 강합성 거더가 제공된다.
