品用型枠。[Scope of Claim for Utility Model Registration] Holes are bored on both sides of the outer form, and a guide part continuous in the circumferential direction and having an inclined surface is provided around the hole on the outer surface of the outer form, and on the tip side. A threaded part is formed, a flange part is formed on the rear end side that protrudes in a direction substantially perpendicular to the axis, and an extension part is formed on the side end side of the flange part, and the entire part forms a substantially cylindrical shape. Inserting the insertion fixing rod into the hole of the outer formwork to form a cylindrical lifting reversal hole with one end closed and the other end opened, and a threaded part formed inside the closed end. The member is placed over the insertion fixing rod protruding from the inside of the outer form, and relative rotation due to the screw engagement between the lifting reversal hole forming member and the insertion fixing rod and the engagement between the guide part and the extension part are achieved. A formwork for concrete products with a lifting reversal hole, characterized in that the outer formwork is held in place by butting, and a lifting reversal hole forming member is held and fixed to the outer formwork.
