摘要： PROBLEM TO BE SOLVED: To provide a method of suppressing occurrence of a fatigue crack in a weld zone between a deck plate and a U-shaped rib of a steel plate floor at low cost.SOLUTION: An abutting portion between a deck plate 11 and a U-shaped rib 12 of a steel plate floor 1 is welded from both an outer surface side 13 and an inner surface side 14 of the U-shaped rib to form an outer weld zone 13 and an inner weld zone 14. Since a larger weld area is achieved compared to a conventional steel plate floor having only the outer weld zone, stress in the weld zones 13 and 14 is dispersed to suppress occurrence of a fatigue crack. Compared to manufacturing of a conventional steel plate floor, increase in man-power results only from a weld work at the inner surface side, causing no steep rise in construction costs. The inner surface side is welded by a dedicated welding device equipped with a weld torch on a carriage, which travels in a closed space inside the rib having a closed section.
摘要翻译：要解决的问题：提供一种低成本地抑制钢板地板的甲板和U形肋之间的焊接区域的疲劳裂纹发生的方法。解决方案：从U形肋的外表面侧13和内表面侧14焊接钢板底板1的甲板11和U形肋12之间的抵接部分，形成外部焊接区域13和内部焊接区域14.与仅具有外部焊接区域的传统钢板地板相比，实现了较大的焊接区域，因此分散焊接区域13和14中的应力以抑制疲劳裂纹的发生。与传统钢板地板的制造相比，人力的增加仅来自内表面侧的焊接工作，不会使施工成本急剧上升。内表面侧通过装配有焊枪的专用焊接装置焊接在滑架上，该滑架在具有闭合部分的肋内的封闭空间中行进。版权所有（C）2012，JPO＆INPIT
