To solve the problem that it is unavoidable in a general method that an anchor bolt is shifted from a reference position which is a position on design where the anchor bolt should be installed originally due to vibrations and errors or the like during construction when curing a foundation in a method that a column part in a structure such as steel frame reinforced-concrete structure is fixed by fastening a column unit to the anchor bolt provided in the state of being buried in the foundation.

A new fixture of an anchor bolt using a washer for fixing the anchor bolt is capable of effectively fixing a column to a desired position even when the anchor bolt is shifted from the reference position without being accompanied by the strength decline of the anchor bolt, by absorbing position deviation of the anchor bolt in a larger allowable range.
