To solve the problems that conventional concrete form presser hardware does not have any water stop plate, which makes it easy for rainwater to penetrate into it from outside, that a body becomes detached when a single tube fastening bolt is turned counterclockwise, and that the hole of the body remains and the repair of mortar becomes required.
The water stop plate is attached in the rear of the concrete form presser hardware, and a groove is provided between the body and the water stop plate and a semicircular projection is provided to the water stop plate so that the water stop plate can remain even when the body has been removed. When the body is removed, the body and the single-tube fastening bolt are made integral with each other. When the body is left, the single-tube fastening bolt becomes detached from the body.
