Abstract:
1. A method of suspending sheet metal air transport duct from a ceiling of a building structure utilizing a support member located between said duct and said ceiling, said duct comprising a plurality of interconnected duct sections, each of said duct sections comprising two terminal open ends and a flange disposed around each of said open ends for abutting connection to the flange of an adjacent duct section of said duct, each said flange comprising a first receiving channel adjacent to a first corner thereof, a second receiving channel that is generally transverse to said first receiving channel and adjacent said first corner, and a first insertable corner member positioned into said first receiving channel and into said second receiving channel, said method comprising the steps of: forming a load-bearing connection between said first insertable corner member and at least one of said first receiving channel and said second receiving channel into which said first inserted corner member is positioned, such that said first insertable corner member is thereafter capable of supporting a predetermined portion of a weight of said duct from said ceiling by connection of said first insertable corner member to said ceiling via said support member; and connecting said first insertable corner member to said ceiling by connecting one of a first and second mating member of said support member to said first insertable corner member, and connecting the other of said first and second mating members to said ceiling to suspend said duct section from said support by said insertable corner member.
