LASER WELDING REINFORCEMENT AND CONCRETE MEMBER WITH BUILT-IN LASER WELDING REINFORCEMENT AND CONNECTION STRUCTURE OF THE SAME
PROBLEM TO BE SOLVED: To shorten a section which cannot be precast when connecting precast concrete structure members with each other by welding both reinforcements on site.SOLUTION: A laser welding reinforcement 2 is formed by forming a flat part 22 on an end of a reinforcement body 21 in axial direction or welding the flat part 22 with the end of the reinforcement body 21 in axial direction. The thickness of the flat part is smaller than the diameter of the reinforcement body 21 excluding the end. The laser welding reinforcement 2 is buried in a concrete member 1 and the flat part 22 of the laser welding reinforcement 2 is made to protrude from an end face of the concrete member 1.SELECTED DRAWING: Figure 1
【課題】プレキャストコンクリートの構造部材同士を、双方の鉄筋を現場で溶接して接合する際の、プレキャスト化できない区間を短縮させる。【解決手段】互いに溶接されるべき、鉄筋本体２１の軸方向の端部に、その端部以外の鉄筋本体２１の径より小さい厚さの平坦部２２を形成して、または平坦部２２を鉄筋本体２１の軸方向の端部に溶接してレーザ溶接用鉄筋２を形成する。このレーザ溶接用鉄筋２をコンクリート部材１内に埋設し、このコンクリート部材１の端面からレーザ溶接用鉄筋２の平坦部２２を突出させる。【選択図】図１
