PROBLEM TO BE SOLVED: To improve earthquake resistance by preventing a connection material connected to upper ends of supporters from coming off.SOLUTION: In the metal fitting 21 for locking of an upper connection material, a suspension piece 25 is abutted on an insertion piece 50 while a hook 22 is locked in such a manner to hold a supporter 12 between an outer peripheral surface 12s and an inner peripheral surface. The suspension piece 25 is fitted into penetration openings 23 formed on side plate parts 21b, and deformation of the suspension piece 25 in a direction separated from the surface (the inner peripheral surface of the supporter 12) of the insertion piece 50 is restricted. Besides, projections 51, 51 are formed on the insertion piece, and the projections 51, 51 are engaged with the penetration openings 23 of the metal fitting 21 for locking. |
