STEEL FLOOR SLAB
PROBLEM TO BE SOLVED: To provide a steel floor slab, for facilitating manufacture by using a raw material in the same as usual, and improving fatigue strength in a welding route part formed in a welding place between a deck plate and a closed cross-sectional rib.SOLUTION: A steel floor slab 1 of applying the present invention comprises a deck plate 2 for applying a live load by extending in the bridge axial direction and formed in a substantially plate shape, a closed cross-sectional rib 3 welded to the reverse surface side B of the deck plate 2 and extending in the bridge axial direction and a groove part 5 formed on the reverse surface side B of the deck plate 2. The closed cross-sectional rib 3 comprises a closed space 30 formed in a closed cross-sectional shape in the bridge axial orthogonal direction X, an edge part 31 installed on the reverse surface side B of the deck plate 2 by melting welding metal 6 and a welding route part 61 formed on the closed space 30 side in a boundary between a reverse surface 2a of the deck plate 2 and the welding metal 6.SELECTED DRAWING: Figure 6
【課題】従来と同様の素材を用いることで製造を容易にして、デッキプレートと閉断面リブとの溶接箇所に形成される溶接ルート部での疲労強度を向上させた鋼床版を提供する。【解決手段】本発明を適用した鋼床版１は、橋軸方向に延びて積載荷重が負荷されるものであり、略板状に形成されたデッキプレート２と、デッキプレート２の裏面側Ｂに溶接されて橋軸方向に延びる閉断面リブ３と、デッキプレート２の裏面側Ｂに形成される溝部５とを備える。閉断面リブ３は、橋軸直交方向Ｘで閉断面形状に形成される閉空間３０と、溶接金属６を溶融することでデッキプレート２の裏面側Ｂに取り付けられる端縁部３１と、デッキプレート２の裏面２ａと溶接金属６との境界で閉空間３０側に形成される溶接ルート部６１とを有する。【選択図】図６
