Column base joint structure
In a column base joint structure (10), an anchor bolt (31) and a column (33) installed upright on a groundsel (32) are tightly joined to each other by using a groundsel-side hardware piece (11) and a column-side hardware piece (12). The groundsel-side hardware piece (11) includes a groundsel-embedded portion (14) and an upper fitting tenon portion (15). A fitting hole (33b) for the upper fitting tenon portion (15) of the groundsel-side hardware piece is formed in a base portion (33a) of the column. The column-side hardware piece includes a lower projecting portion (16) projecting downward from a top face portion (33c) to the inside of the fitting hole (33b), and a column-embedded portion (17) positioned above the top face portion (33c). A pin locking hole (15a) in the upper fitting tenon portion (15) of the groundsel-side hardware piece and a pin locking hole (16a) in the lower projecting portion of the column-side hardware piece are aligned with each other, a driftpin is hammered into the aligned pin locking holes, and the anchor bolt and the column are thereby tightly joined to each other.
