PROBLEM TO BE SOLVED: To solve the problem of a conventional reinforced concrete form pressing metal fitting which may allow penetration of rainwater and the like after removal of a body since the metal fitting forms a groove in a surface contacting with form plywood, has a large bore diameter because of a hexagonal portion arranged on the outside of a thread part, and has no water stop. SOLUTION: When a hexagon portion with the same dimension as that of an outside diameter of a bolt is attached at the end of the single pipe fastening bolt, a bore diameter of a face contacting with form plywood can be reduced. By fitting a post-mounting water stop is fitted into the concrete inside face portion side, the water stop is left in the concrete inside when the body is removed from the concrete, and water stopping effect against rainwater is improved.
