PPROBLEM TO BE SOLVED: To provide an easy connecting structure of a metallic vertical sash bar of a metallic inner wall frame and a metallic vertical sash bar for an opening part, for reducing manhours of work. PSOLUTION: One end side of a metallic connecting columnar member having a locking claw projecting outside from an intermediate part in the longitudinal direction in a cross-sectional hollow shape, is fitted and inserted until the locking claw is locked on the upper end of the metallic vertical sash bar, from the upper end of the metallic vertical sash bar connected to the lower end. The metallic vertical sash bar connected to the upper side is fitted and inserted up to locking on the locking claw from the upper end on the other end side of the connecting columnar member. The mutual metallic vertical sash bars of the upper-lower metallic inner wall frames, are vertically connected via the metallic vertical sash bar for the opening part, by respectively fixing an overlapping part of the metallic vertical sash bar and the connecting columnar member by a fixture so that the upper-lower metallic vertical sash bars dropout from the connecting columnar member.
