Method and apparatus for suspending duct by inserted corner members

A duct section of an air transport duct that is capable of connection to a support by means of a plurality of support members located between said duct and said support, said duct section 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, wherein said first insertable corner member is attached to at least one of said first receiving channel and said second receiving channel by means of a load-bearing connection therebetween, such that said first insertable corner member is thereafter capable of supporting a predetermined portion of a weight of said duct by connection of said first insertable corner member to one of said plurality of support members.

An air transport duct for connecting to a support by means of a plurality of support members located between said duct and said support, said duct comprising a plurality of interconnected duct sections, each of said duct sections comprising two terminal open ends and a flange positioned 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, wherein each said first insertable corner member is attached to at least one of said first receiving channel and said second receiving channel into which each said first inserted corner member is positioned by means of a load-bearing connection therebetween, such that each said first insertable corner member is capable of supporting a predetermined portion of a weight of said duct by connection of each said first insertable corner member to one of said plurality of support members.

An attachment member for connecting an air transport duct to a support by means of a support member located between said duct and said support, said attachment member having first and second mating members that are connectable to one another, said first mating member providing a first connector for securing said attachment member to a duct section of said duct, said second mating member providing a second connector for securing said attachment member to said support member.

A method of connecting an air transport duct to a support by means of a plurality of support members located between said duct and said support, 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 a flange of an adjacent duct section of said duct, each said flange comprising a first flange wall adjacent to a first corner thereof, a second flange wall that is generally transverse to said first flange wall and adjacent said first corner, and a first corner member positioned adjacent to said first flange wall and to said second flange wall, said method comprising the steps of:

• forming a load-bearing connection between each said first corner member and at least one of said adjacently positioned first flange wall and said second flange wall, such that each said first corner member is thereafter capable of supporting a predetermined portion of a weight of said duct by connection of each said first corner member to one of said plurality of support members;
• and forming a connection between at least one of said first insertable corner members to one of said plurality of support members.

An air transport duct for connecting to a support by means of at least one support member located between said duct and said support, said duct comprising at least one duct section, each of said at least one duct section comprising two terminal open ends and a flange positioned around each of said open ends for abutting connection to the flange of a corresponding duct section, 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, wherein each said first insertable corner member is attached to at least one of said first receiving channel and said second receiving channel into which each said first inserted corner member is positioned by means of a load-bearing connection therebetween, such that each said first insertable corner member is capable of supporting a predetermined portion of a weight of said duct by connection of each said first insertable corner member to one of said at least one support member.
