板体と注入材との接着性や密着性を損なうことがない。According to the first aspect of the present invention, a flat plate bolt having an internal thread is used for fastening the plate body and the concrete structure, so that the injection material is injected between the plate body and the concrete structure. In addition, there is no need to temporarily hold the holding member by positioning the holding member between the bolt head and the plate body. Therefore, when removing the retainer, it is not necessary to remove the bolts that fasten the plate and concrete structure as before,
There is no loss of adhesion or adhesion between the plate and the injection material.
