る。When the drilling of the mounting holes 18 is completed in this way, as shown in FIG. 3B, the proximal end of the tapping screw 17 is screwed into the proximal internal thread 13a of the sheet pile retainer 13. , Connect the two. At this time, the tapping screw 17 need only be lightly screwed in manually.
As will be described later, the tapping screw 17 is rotated by turning the sheet pile retainer 13 to forcibly screw the tapping screw 17 into the mounting hole 18 so that the tapping screw 17 is turned into the proximal female screw portion 13.
This is because it is screwed firmly to the end of a and fixed.

ることができる。Next, the tip of the tapping screw 17 is inserted into the mounting hole 18 and the electric drill 15 is activated to rotate the sheet pile retainer 13. Then, the tapping screw 17 is forcibly screwed into the mounting hole 18, and the sheet pile retainer 13 is mounted on the outer surface of the metal column 1 as shown in FIG. 2. At this time, since the electric drill 15 has a built-in torque limiting mechanism as described above, when the tapping screw 17 is screwed into the mounting hole 18 and the sheet pile retainer 13 contacts the metal column 1 at a predetermined pressure, the sheet pile retainer is set. The rotation drive of the metal fitting 13 automatically stops. For this reason, the tightening force (screw-in force) of the tapping screw 17 is always constant, and the connection strength can always be constant.

Since the sheet pile retainer 13 is attached to the metal column 1 by forcibly screwing it into the metal column 8, even if mud or concrete adheres to the outer surface of the metal column 1, it is not removed without removing them. A stable connection strength is always obtained. In addition, work can be performed without any trouble even in rainy weather or snowfall. Further, since an electric tool can be used, the work can be completed in a short time, and a large force is not required.

7 is screwed into the mounting hole 18, or the tapping screw 17 is rotated together with the sheet pile retainer 13 and screwed into the mounting hole 18, and then only the sheet pile retainer 13 is removed. A state in which the retainer 13 is removed can be obtained. For this reason, there is no possibility that the sheet pile retainer 13 will be in the way when the reinforcing bars are laid. In particular, in the case where the reinforcing bars assembled in a cage shape are arranged by suspending them from above, the sheet metal retainer 13 is effective because the reinforcing bars may not be able to contact the reinforcing bars and be hung down. . After the reinforcing bars are arranged in the removed sheet pile retainer 13, for example, a hexagonal box spanner 16 having a long dimension may be mounted on the electric drill 15 and connected to the tapping screw 17 through the space between the reinforcing bars.
