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

摘要： PROBLEM TO BE SOLVED: To improve the function by providing a shoe apparatus for movably supporting an end of a structure on a base stand, and a shoe apparatus for linearly and swingingly supporting the end of the structure on the base stand. SOLUTION: A bridge 1 is constructed by sequentially connecting fixed bridge girders 5, 6 to buffer girders 3, 4 arranged on both sides of a floating bridge 2, respectively. The girders 3, 4 have one ends 13, 16 thereof mounted on piers 8, 9 by support apparatuses 41, 43, respectively, and the other ends 31, 34 thereof mounted on piers 33, 36 by support apparatuses 42, 44, respectively. The support apparatuses 41, 43 have first shoe apparatuses for movably supporting the ends 13, 16 on the piers 8, 9, respectively, and second shoe apparatuses for being rotatably connected to the piers 8, 9, respectively. The first shoe apparatus includes a predetermined structure formed of a roller means, and the second shoe apparatus includes a predetermined structure formed of a spherical bearing, a slide bearing, etc. The apparatuses 42, 44 linearly and swingingly support the ends 31, 34, respectively, by the first shoe apparatuses, and shoe apparatuses each formed of a plate-like bearing and a spherical bearing. Thus, one end of a structure can be rotatably connected to a floating type structure, or the like.

摘要： PROBLEM TO BE SOLVED: To improve the function of a shoe apparatus by arranging a roller, first and second shafts, a linking member, and an attaching stand in a predetermined state, and make the roller rotatable with respect to the linking member. SOLUTION: A shoe apparatus 1 is constructed by attaching a shaft means 3 having a roller means 2 mounted thereon to a linking member 4, and attaching an attaching stand 6 to a shaft member 5 mounted on the member 4. Next, the apparatus 1 allows the shaft 3 to be mounted on a lower surface of one end of a bridge in a manner being orthogonal to the bridge axis direction and the shaft 5 in a manner being orthogonal to a bridge width direction, respectively. The roller 2 is made rotatable on the shaft 5 with respect to the member 4, and the attaching stand 6 is made rotatable on the shaft 5 with respect to the linking member 4. Thus, even when a long and heavy structure is coped with, expansion due to vibrations and thermal inflation and deflection in a direction orthogonal to the longitudinal direction can be accommodated. Further, generation of excessive horizontal inner stress at the base stand can be prevented. Therefore, one end of the structure can be movably supported by the base stand, and the one end can be easily set on the base stand.

摘要： PROBLEM TO BE SOLVED: To prevent cracks of a reinforced concrete floor slab of a continuous beam of a bridge. SOLUTION: A steel main beam 3 is installed on the top of piers 1, 1', and a reinforced concrete floor plate 4 is formed on the upper surface and the middle upper surface of the steel main beam 3 excluding a beam end part upper surface 3'. By a downward force from a deflecting force-adding device 10 comprising an upper sheave 11 installed under a simple beam 2 formed with the steel main beam 3 and the reinforced concrete floor plate 4, lower sheaves 12, 12 installed under the piers 1, 1', wire ropes 13 hooked to them, and a wire rope pulling-in means 14 for pulling in these wire ropes 13, the simple beams 2, 2 are deflected so as to expand the upper clearance between the beam end faces 3c, 3c of adjacent simple beams 2, 2 and form a reinforced concrete lateral beam in that clearance. Then a connection part reinforced concrete floor plate 4 is formed with the reinforced concrete lateral beam and the beam end part upper surface 3' to cancel the downward force. Thus, because a prestressed force is introduced into the reinforced concrete floor plate 4, cracks will not occur.
