To provide a reinforcing member capable of securing a sufficient amplitude movement range of a welding torch and performing a sound welding by widening the expansion of an initial layer weld part without having to provide a root gap at the time of butt welding.SOLUTION: In a beam reinforcing member 4, a peripheral side surface 5 is formed into a smooth curved surface shape such that the outer diameter of an insertion side end surface 4T is the smallest and the outer diameter thereof expands toward the end as the distance from the insertion side end surface 4T increases. The beam reinforcing member includes: an insertion part 4A in which the peripheral side surface 5 comes into contact with an opening forming lower end part 2A1 of an opening forming surface 2A of a through hole 2 when the insertion is made from the insertion side end surface 4T into the through hole 2 of a web 1A, at a part SS1 where the outer diameter is larger than the inner diameter of the through hole 2; and a non-insertable part 4B whose longitudinal section is hollow and cylindrical, which is continuous with the insertion part 4A and has an outer diameter larger than that of the through hole 2 and cannot be inserted into the through hole 2.SELECTED DRAWING: Figure 3
【課題】突き合わせ溶接の際にルートギャップを設ける必要もなく、初層溶接部の広がりを広くできるので溶接トーチの十分な振幅運動範囲が確保できて健全な溶接が行える補強部材を提供すること。【解決手段】梁補強部材４は挿入側先端面４Ｔの外径が最も小さく前記挿入側先端面４Ｔより離れるに従って末広がりにその外径が広がるような周側面５が滑らかな曲面状に形成されると共に前記挿入側先端面４Ｔからウェブ１Ａの貫通孔２に挿入された際に前記貫通孔２の開口形成面２Ａの開口形成下端部２Ａ１に前記貫通孔２の内径よりその外径が大きくなる部位ＳＳ１において前記周側面５が当接する挿入部４Ａと、この挿入部４Ａに連なり且つ前記貫通孔２より外径が大きくて前記貫通孔２内に挿入できない縦断面が中空円柱状を呈する挿入不可部４Ｂとを備えている。【選択図】図３
