Abstract
A flange to be assembled to a duct member includes a plurality of pre-fabricated apertures or areas of weakened wall strength for receiving fasteners to assemble the flange to the end of a duct member. The apertures may be spaced apart such that the fasteners can be inserted at regular intervals along the length of the flange and the length of the end of the duct member.
Claims19
A duct member panel flange, comprising:
- a first wall member;
- a second wall member, which wall members are configured to receive a duct member panel there between, wherein at least a portion of the first wall member and at least a portion of the second wall member extend substantially parallel one another;
- an intermediate member connected to the first and second wall members;
- and
- a plurality of first pre-fabricated apertures disposed in the first wall member, and a plurality of second pre-fabricated apertures disposed in the second wall member, wherein the first pre-fabricated apertures are substantially aligned with the second pre-fabricated apertures.
A method for manufacturing a duct member panel flange, comprising:
- forming a flange into a unitary configuration that includes a first wall member, a second wall member, and an intermediate member connected to the first and second wall members, which intermediate member includes a rib disposed proximate the first wall member, wherein at least a portion of the first wall member and at least a portion of the second wall member extend substantially parallel one another;
- forming a plurality of first pre-fabricated apertures within the first wall member;
- and
- forming a plurality of second pre-fabricated apertures disposed in the second wall member, wherein the first pre-fabricated apertures are substantially aligned with the second pre-fabricated apertures;
- wherein the plurality of first pre-fabricated apertures are disposed in the portion of the first wall member that is substantially parallel the second wall member, and the plurality of second pre-fabricated apertures are disposed in the portion of the second wall member that is substantially parallel the first wall member.
The method of 9, wherein the step of forming the flange into the unitary configuration includes forming the rib to extend outwardly from the first flange panel in a direction that is substantially parallel to the first wall member, and is spaced apart from the first wall member.
A duct member panel flange, comprising:
- a first wall member;
- a second wall member, which wall members are configured to receive a duct member panel there between, wherein at least a portion of the first wall member and at least a portion of the second wall member extend substantially parallel one another;
- an intermediate member connected to the first and second wall members;
- and
- a plurality of first pre-fabricated fastener entry areas in the first wall member, and a plurality of second pre-fabricated fastener entry areas in the second wall member, wherein the first pre-fabricated fastener entry areas are substantially aligned with the second pre-fabricated fastener entry areas.
A duct member panel flange, comprising:
- a first wall member;
- a second wall member, which wall members are configured to receive a duct member panel there between, wherein at least a portion of the first wall member and at least a portion of the second wall member extend substantially parallel one another;
- an intermediate member connected to the first and second wall members;
- and
- a plurality of pre-fabricated fastener entry areas in at least one of the first wall member or the second wall member.
