CLOSED CROSS SECTION RIB STEEL FLOOR SLAB
To provide a steel floor slab capable of accurately preventing deck penetrating cracks in a closed cross section rib steel floor slab.SOLUTION: A closed cross section rib steel floor slab (1) comprises: a deck plate (11) which is formed into an approximately plate shape; and a closed cross section rib (12) which is welded to a back surface side of the deck plate (11) and extends in a bridge axis direction. The closed cross section rib (12) has: a close space (9) formed into a closed cross section shape in a bridge axis orthogonal direction; and an edge surface (13) attached to the back surface side of the deck plate (11) by melting a weld metal (15). A flat surface (13a) in which one long side of the edge surface (13) of the closed cross section rib (12) is chamfered is provided, the chamfered flat surface (13a) is brought into contact with the back surface of the deck plate (11) in approximately parallel. A part or all of the flat surface in contact with the back surface has an unwelded part. The edge surface (13) of the closed cross section rib (12) and the back surface of the deck plate (11) are groove weld.SELECTED DRAWING: Figure 1
【課題】閉断面リブ鋼床版のデッキ貫通き裂を的確に抑制できる鋼床版を提供する。【解決手段】略板状に形成されたデッキプレート（１１）と、デッキプレート（１１）の裏面側に溶接されて橋軸方向に延びる閉断面リブ（１２）と、を備え、閉断面リブ（１２）は、橋軸直交方向で閉断面形状に形成される閉空間（９）と、溶接金属（１５）を溶融することでデッキプレート（１１）の裏面側に取り付けられる端面（１３）と、を有し、閉断面リブ（１２）の端面（１３）の一長辺が面取りされた平面（１３ａ）を持ち、面取りされた平面（１３ａ）をデッキプレート（１１）の裏面に略平行に接触させ、前記接触している平面の一部または全部に未溶着部を有し、閉断面リブ（１２）の端面（１３）とデッキプレート（１１）の裏面とが開先溶接されている、閉断面リブ鋼床版（１）である。【選択図】図１
