PROBLEM TO BE SOLVED: To prevent a damage to a head and a pile driving part of a pile driver, and ensure stability of a position of the head relative to a U-shaped pile.SOLUTION: A head 1 is used for driving a roughly U-shaped pile 2 having two perpendicular parts 2a that face each other and integrated by a horizontal part 2b connected at respective top edges, the head including: a body part 3 having a first plate material 3a in a longer-side direction and a second plate material 3b in a shorter-side direction; an open hole 4 penetrating the body part 3 in a vertical direction and formed in the longer-side direction; a pair of guiding protrusions 6 disposed at an end in the longer-side direction or the shorter-side direction of the body part 3, and guided along a guiding apparatus 5; and a recess 7 formed on a bottom surface into which the horizontal part 2b is inserted.SELECTED DRAWING: Figure 1
【課題】 ヘッドや杭打機械械の打設部の破損を防止することができ、ヘッドのコ字杭に対する位置の安定性を確保できる。【解決手段】 ヘッド１は、二本の垂直部２ａが対向し各々の上端において水平部２ｂで連結された略コの字形状に一体化されたコ字杭２を打ち込む際に使用するもので、長手方向の第１板材３ａと短手方向の第２板材３ｂを有する本体部３と、本体部３の上下方向に貫通し長手方向に形成される貫通孔４と、本体部３の長手方向又は短手方向の端部に設けられ、案内器具５に沿って案内される一対の案内凸部６と、底面に設けられて水平部２ｂを差し込む凹部７と、を備える。【選択図】図１
