To provide a technique allowing improvement of fatigue durability of a reinforced concrete slab.SOLUTION: A reinforced concrete slab 1 in accordance with the present invention has: concrete 2 having a surface 21 on which a wheel load acts; lattice-shaped reinforcement bars 3 arranged in the concrete 2 and formed along the surface 21 in a lattice shape; and rod members 6 arranged in the concrete 2 and extended in a vertical direction. The lattice-shaped reinforcement bars 3 have upper side lattice-shaped reinforcement bars 4 and lower side lattice-shaped reinforcement bars 5 arranged below the upper lattice-typed reinforcement bars 4, and the rod members 6 are rigidly connected on the upper side lattice-shaped reinforcement bars 4 and the lower side lattice-shaped reinforcement bars 5.SELECTED DRAWING: Figure 2 【課題】鉄筋コンクリート床版の疲労耐久性を向上させることが可能となる技術を提供する。【解決手段】本発明に係る鉄筋コンクリート床版１は、輪荷重が作用する表面２１を有するコンクリート２と、コンクリートの内部２に配置されるとともに、表面２１に沿って格子状に形成される格子状鉄筋３と、コンクリート２の内部に配置されるとともに、上下方向に延伸される棒部材６と、を備える。格子状鉄筋３は、上側格子状鉄筋４と、上側格子状鉄筋４の下方側に配置される下側格子状鉄筋５と、を有し、棒部材６は、上側格子状鉄筋４と下側格子状鉄筋５とに剛結されることを特徴とする。【選択図】図２
