STEEL PLATE FLOOR AND STEEL PLATE FLOOR MANUFACTURING METHOD
To provide a steel plate floor and a steel plate floor manufacturing method which can suppress the occurrence of fatigue cracks in a root part of a weld between a longitudinal rib and a deck plate without performing any special treatment after welding.SOLUTION: A steel plate floor 100 comprises: a deck plate 3 having a first surface 3a and a second surface 3b; a longitudinal rib 6 forming a closed cross section with the second surface 3b of the deck plate 3; and a pair of welds 30a, 30b extending in the longitudinal direction of the longitudinal rib 6 and formed from the outside of the longitudinal rib 6 so as to join the deck plate 3 and the longitudinal rib 6. The welds 30a, 30b include weld metals 32a, 32b melted into the deck plate 3. In the thickness direction of the deck plate 3, the penetration depth of the weld metals 32a, 32b into the deck plate 3 is one third or more of the thickness of the deck plate 3.SELECTED DRAWING: Figure 9
【課題】溶接後に特別な処理を施すことなく縦リブとデッキプレートとの溶接部のルート部に疲労亀裂が発生することを抑制できる鋼床版およびその鋼床版の製造方法を提供する。【解決手段】鋼床版１００は、第１面３ａおよび第２面３ｂを有するデッキプレート３と、デッキプレート３の第２面３ｂとの間で閉断面を形成する縦リブ６と、デッキプレート３と縦リブ６とを接合するように縦リブ６の長さ方向に延びかつ縦リブ６の外側から形成されている一対の溶接部３０ａ，３０ｂとを備える。溶接部３０ａ，３０ｂはデッキプレート３に溶け込んだ溶接金属３２ａ，３２ｂを含む。デッキプレート３の厚み方向において、溶接金属３２ａ，３２ｂのデッキプレート３への溶け込み深さは、デッキプレート３の厚みの１／３以上である。【選択図】 図９
