Claims

[Scope of utility model registration request]

Bend the upper and lower ends of an appropriately wide vertical board inward, and drill a hole for a concrete formwork tightening rod in the middle of the vertical piece of the vertical board in the width direction. On both sides except for the center part, there are narrow vertically long upper ribs on both sides that protrude outward from the top of the vertical piece to the upwardly bent piece and are opposed to each other, and ribs that protrude outward from the bottom of the vertical piece to the downwardly bent piece. In addition to providing narrow and vertically long lower ribs on both sides facing each other, the lower end of the upper rib on one side is appropriately higher than the lower end of the upper rib on the other side, and the upper end of the other lower side rib is set higher than the upper end of the lower rib on the other side. The outer edge of the lower end of the upper rib on one side is tapered diagonally inwardly downward, and the outer edge of the upper end of the rib on the lower other side is tapered diagonally inwardly upward. An outwardly rising piece is provided on both sides in the middle in the lengthwise direction of the piece, and slightly overlaps with the above upper and lower both side ribs, and the upper and lower both sides ribs, as well as the tapered edge of the upper side rib and one side thereof are provided. A concrete formwork tightening washer in which the tapered edge of the rising piece and the lower other side rib and the other side rising piece respectively guide a wedge to be driven into the wedge hole of the concrete formwork tightening rod.
