STEEL BEAM WITH FLOOR SLAB
To provide a steel beam with a floor slab that can reduce the amount of steel while suppressing local buckling and lateral buckling of the steel beam.SOLUTION: Provided is a steel beam 1A with a floor slab, in which a floor slab 6 is provided on the upper side of a steel beam 3. The steel beam includes a beam end portion 4 provided along a material axis direction D1, and a beam center portion 5 in which one or both of flanges 51, 52 and a web 53 are thinner than the plate thickness of the beam end portion 4. The flanges 42 and 52 located below each of the beam end portion 4 and the beam center portion 5 are not provided with a member to prevent lateral buckling in a direction intersecting the material axis direction D1. A plurality of steel anti-slip members 7A embedded in a concrete 61 of the floor slab 6 are joined to the upper surfaces of the upper flanges 41 and 51 of each of the beam end portion 4 and the beam center portion 5. Steel anti-slip members 72 at the beam center portion 5 have a larger cross-sectional area or number of pieces per unit length than steel anti-slip members 71 at the beam end portion 4.SELECTED DRAWING: Figure 1
【課題】鉄骨梁の局部座屈・横座屈を抑制しつつ、鋼材量を低減可能な、床スラブ付き鉄骨梁を提供する。【解決手段】床スラブ付き鉄骨梁１Ａは、鉄骨梁３の上部側に床スラブ６が設けられ、材軸方向Ｄ１に沿うように設けられた梁端部４と、フランジ５１、５２とウェブ５３のいずれか一方または双方が梁端部４の板厚に比べて薄い梁中央部５と、を備え、梁端部４と梁中央部５の各々の下側に位置する前記フランジ４２、５２には、材軸方向Ｄ１に交差する方向への横座屈を防止する部材が設けられておらず、梁端部４と梁中央部５の各々の、上側に位置するフランジ４１、５１の上面には、床スラブ６のコンクリート６１に埋設される、複数の鋼製のずれ止め材７Ａが接合され、梁中央部５の鋼製のずれ止め材７２は、梁端部４の鋼製のずれ止め材７１に比べて、単位長さ当りの断面積または本数が大きい。【選択図】図１
