PILE DRIVING HAMMER
To provide a pile driving hammer with high durability that can strike a pile forcefully at the time of both vertically downward strikes and strikes with arcing trajectories.SOLUTION: A connection hole 4 penetrates one longitudinal surface 3a of a substantially rectangular head body 3, and the tip of a pipe handle 5 is connected to the connection hole 4 in an inserted manner. A plug 8 contacting a pile head 7a is fitted into the tip of the pipe handle 5. A strike reception surface 9 where the pipe handle 5 contacts a tip 8a of the plug 8 is formed on the deep surface of the connection hole 4 of the head body 3. The plug 8 has a length that protrudes from the one longitudinal surface 3a of the head body 3.SELECTED DRAWING: Figure 1
【課題】 杭打ちを上下垂直の振り下ろしも円弧軌跡の振り下ろしも、高耐久性を有して強打できるようにする。【解決手段】 略長方体形状の頭部体３の一長面３ａに連結穴４を穿孔し、この連結穴４にパイプ柄５の先端を挿入して連結している。前記パイプ柄５の先端内部に杭頭７ａと当接するプラグ８を嵌入し、頭部体３の連結穴４の奥面にパイプ柄５とプラグ８の先端８ａが当接する打撃受け面９を形成し、前記プラグ８を頭部体３の前記一長面３ａから突出する長さとしている。【選択図】図１
