PROBLEM TO BE SOLVED: To develop a technology capable of shortening the embedding length to a concrete skeleton of an expanded post-construction anchor, by improving extraction yield strength from the concrete skeleton required for the expanded post-construction anchor. SOLUTION: The anchor fixing structure, the anchor construction method and the vessel construction method, use an anchor 1 for installing a vessel 5 to the concrete skeleton 4, by driving and fixing the expanded post-construction anchor 1 in and to this concrete skeleton 4, by adopting the concrete skeleton 4 being prestressed concrete.
