TENSION INTRODUCING METHOD TO ANCHOR BOLT FOR FIXING BASE OF COLUMN

Japanese Patent JP3323939

B2

PROBLEM TO BE SOLVED: To provide a method by which the fixing force on the raising foundation of the base of a column can be sufficiently secured, and also the construction period can be shortened by enabling the plumbing adjustment of the base of the column without placing level mortar, and by enabling the introduction of large tension to the anchor bolt for fixing the base of the column making a background of sufficient strength of grout or the like.
SOLUTION: In the fixing structure of the base of a column, a nearly horizontal base plate 5 to which the base of a column 6 of a nearly vertical structure has been connected is fixed on a raised foundation 1 by interposing grout 3 or the like by means of anchor bolts 2 that has been subjected to unbond treatment 11 and anchor nuts 4, and also level nuts 10 that are screwed on the anchor bolt 2 so as to be abutted on the base plate 5 for adjusting the level of the base plate 5 are arranged. In that case, a tension is introduced in the anchor bolt 2 for fixing the base column by interposing a deformation washer 8 that is deformed in the axial direction by a prescribed load exceeding the dead weight of the base column 6 between the base plate 5 and the level nut 10.
