COMPOSITE GIRDER A BRIDGE CONSTRUCTED USING THE SAME
PROBLEM TO BE SOLVED: To provide a composite girder capable of facilitating construction work to construct a bridge by reducing the girder height and weight of the bridge while requiring no rust prevention measures of steel material, and a bridge constructed by using the same.SOLUTION: A composite girder 1 is constituted of: a T-shaped steel material 2 which has a flange 22 on at least lower edge of a web 21; and a concrete bottom slab 3 which encloses the flange 22 of the T-shaped steel material 2 and allows the web 21 to protrude therefrom. The bridge 5 is constructed, on the composite girder 1 bridged between bridge abutments 53, 53 arranged parallel to each other perpendicular to an extension direction thereof, a cast-in-place concrete 52 is carried out over a buried formwork 56, which is bridged over the concrete bottom slabs 3, and the concrete bottom slab 3 to bury the web 21 of the T-shaped steel material 2 in the cast-in-place concrete 52.SELECTED DRAWING: Figure 16
【課題】鋼材の防錆対策を不要にしながら、桁高を抑えて橋梁の重量を軽減し、橋梁を構築する際の施工を容易にする合成桁と、これを用いて構築される橋梁とを提供する。【解決手段】ウェブ21の少なくとも下縁にフランジ22を有するＴ型鋼材２と、前記Ｔ型鋼材２のフランジ22を包み、ウェブ21を突出させるコンクリート底版３とから構成される合成桁１である。橋梁５は、延在方向に直交して並べて橋台53,53間に架け渡した合成桁１に対して、コンクリート底版３間に架け渡す埋設型枠56と前記コンクリート底版３とにわたって現場打コンクリート52を打設し、Ｔ型鋼２材のウェブ21を前記現場打コンクリート52に埋没させて構築する。【選択図】図16
