A corner angle assembly for a structure, such as a duct work, has first and second angle pieces inserted through the respective openings in triangularly-shaped connecting flanges spot-welded to the respective walls of the structure. A first piece is inserted into its respective flange and has a contact portion extending beyond the opening in the flange. This contact portion has a groove for slidably receiving the second angle piece. The second angle piece has an upwardly-extending edge engaging the first piece for limiting the degree of insertion of the second piece. The first piece has a protruding portion bent over a beveled edge on the second piece for precluding the withdrawal of the second piece. Cooperating aligned holes in the extending portions of the respective pieces facilitate the passage of bolts or other suitable securing means. At least one of the pieces, preferably the first, is provided with an upwardly-extending reinforcing bridge engaging the adjacent side wall of the respective connecting flange. |
