Abstract

In a column base joint structure, an anchor bolt and a column installed upright on a groundsel are tightly joined using groundsel-side and column-side hardware pieces. The groundsel-side hardware piece includes groundsel-embedded and upper fitting tenon portions. A fitting hole for the upper fitting tenon portion of the groundsel-side hardware piece is formed in a base of the column. The column-side hardware piece includes a lower projecting portion projecting downward from a top face portion to the inside of the fitting hole, and a column-embedded portion positioned above the top face portion. A pin locking hole in the upper fitting tenon portion of the groundsel-side hardware piece and a pin locking hole in the lower projecting portion of the column-side hardware piece are mutually aligned, a driftpin is hammered into the aligned pin locking holes, and the anchor bolt and the column are thereby tightly joined to each other.
