題点を有している。The above anchor bolt is formed by drilling a pilot hole in the anchor bolt embedding portion, driving a cylindrical body into the pilot hole, and screwing the anchor bolt into the cylindrical body. Although this is effective as a means for firmly attaching the anchor, it is only a heavy connection as an anchor member, which is sufficient mainly with a certain retaining force, and has a drawback in that it requires much labor and costs. In addition, there is a problem that the prepared wall is damaged.

In this method, an annular blade called a bowl-shaped portion is formed in multiple stages in the axial direction on the peripheral surface of the cylindrical portion, and this annular blade is externally fixed to the main trunk of the joint with the cylindrical portion, and inserted into the pipe. At times, the annular blade is bent in a cylindrical shape in a direction opposite to the insertion direction and presses against the inner peripheral surface of the pipe to press the blade outer peripheral surface, and the pressure contact prevents the pipe from being pulled out of the pipe. ing.

In the case of a relatively rough prepared hole drilled in a wall or the like, the hole cannot follow the inner peripheral surface of the prepared hole in a following manner, which causes a decrease in anchor strength.

Each elastic claw is bent freely at the time of press-fitting into the prepared hole, and its tip is pressed and contacted with the inner peripheral surface of the prepared hole by the resilient force.
