Claims

[Scope of utility model registration request]

In a pile driver that grips the upper end of a foundation pile and pushes it into the ground while rotating, it is attached to the rotating shaft of a rotary drive source that can move up and down along the league of the pile driver. a chucking member capable of suspending the upper end of the foundation pile from the base pile, and a mounting member attached to the lower part of the rotating shaft;
It consists of a suspension member fixed to the lower surface of the mounting member through an intermediate member, and the suspension member has a large diameter hole located on a circumference coaxial with the rotation axis and a large diameter hole continuous thereto. At least two engaging holes are provided that are connected to the small diameter hole, and the large diameter hole of the retaining hole is formed so that the head of the suspension bolt installed on the upper end surface of the foundation pile can be inserted therein. At the same time, the small diameter hole is formed so that the shaft of the suspension bolt can pass therethrough, and the head of the suspension bolt passes through the large diameter hole of this holding hole, and the shaft of the suspension bolt passes through the large diameter hole. A chucking member for a foundation pile, characterized in that it is relatively moved in the circumferential direction from a large-diameter hole of an engagement hole and positioned in a small-diameter hole by rotation of the mounting member by the rotational drive source as described in the appendix. −
