STEEL FLOOR SLAB, REINFORCEMENT METHOD AND MANUFACTURING METHOD OF STEEL FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a steel floor slab for restraining an increase in an inter-fulcrum distance of a deck plate more than a steel floor slab after remodeling by a reinforcement method of using a conventional connection-fixation member.SOLUTION: A steel floor slab comprises a connection-fixation member 16 for fixing a closed cross-sectional rib 14 to a deck plate 12 by connecting between an undersurface of the deck plate 12 and an outside surface of the closed cross-sectional rib 14, and the connection-fixation member 16 is arranged along the undersurface of the deck plate 12 and the outside surface of the closed cross-sectional rib 14, and a part between the connection-fixation member 16 and the undersurface of the deck plate 12 and a part between the connection-fixation member 16 and the outside surface of the closed cross-sectional rib 14, are fixed by mechanical fastening means 18 and 20, and the connection-fixation member 16 comprises a bending part 16B of bending in a dogleg-shape in a cross-sectional shape when cut in a plane orthogonal to the longitudinal direction of itself, and the connection-fixation member 16 is also formed by overlapping a thin-plate steel- plate 16A in a plurality of sheets.SELECTED DRAWING: Figure 3
【課題】デッキプレートの支点間距離の増加が、従来の連結固定部材を用いた補強工法による改造後の鋼床版よりも抑制された鋼床版を提供する。【解決手段】デッキプレート１２の下面と閉断面リブ１４の外側面との間を連結して、閉断面リブ１４をデッキプレート１２に固定する連結固定部材１６を備え、連結固定部材１６は、デッキプレート１２の下面および閉断面リブ１４の外側面に沿うように配置されていて、連結固定部材１６とデッキプレート１２の下面との間、および連結固定部材１６と閉断面リブ１４の外側面との間は、機械的な締結手段１８、２０により固定されており、かつ、連結固定部材１６は、自身の長手方向と直交する平面で切断したときの断面形状がくの字状に屈曲していて屈曲部１６Ｂを有しており、さらに、連結固定部材１６は、薄板鋼板１６Ａが複数枚重ねられて形成されている。【選択図】図３
