PROBLEM TO BE SOLVED: To provide a structure for tightening and securing a member to be secured to an installation surface capable of absorbing (also eliminating) the displacement of a hole position in the member relative to an anchor bolt by a simple operation and of firmly securing the member on the installation surface. SOLUTION: The embedded anchor bolt 38 is installed vertically from a foundation or a floor concrete 38. A beam cut part 32 is formed on a divided beam 34 serving as a floor girder 18. An excessive relief hole 40 is formed in the lower flange 34C of the divided beam at the end. The projecting part 42B of an auxiliary metal fitting 42 is rotatably fitted to the excessive relief hole 40. An elongated hole 44 through which the embedded anchor bolt 38 is inserted is formed in the base part 42A of the auxiliary metal fitting 42. Since a nut is screwed with the embedded anchor bolt 38 inserted into the elongated hole 44, the end of the divided beam 34 is secured to the installation surface. COPYRIGHT: (C)2009,JPO&INPIT
