PURPOSE: To enable the formation of a concrete structure joint large in tension resistance and shearing force resistance by filling adhesive to fix joint fastening material inserted into a fastening material insertion hole and a fastening material carry-in passage.

CONSTITUTION: The end face 2 of one concrete structure 1 to be fastened is brought into contact with the end face of the other concrete structure 1 below, and a gasket stretched on the end face 2 of one concrete structure 1 is brought into contact with the end face 2 of the other concrete structure 1. Joint fastening material 18 is then inserted from the starting end part of a fastening material carry-in passage 10, and its tip part is inserted into the back of the fastening material insertion hole 9 of the other concrete structure 1 below. Adhesive is then filled into the fastening material insertion hole 9 and fastening material carry-in passage 10 through the center through hole or the like of the joint fastening material 18 so as to be filled around the joint fastening material 18. The hardening of the adhesive is accelerated by applying a current to a heating wire or the like if necessary.
