SHEET METAL FRAMING MEMBER HAVING A J-SHAPED FLANGE
Abstract
A sheet metal framing member having a J-shaped retention flange
is disclosed herein. The innovative sheet metal framing member is
made from a continuous piece of sheet metal and is especially
configured for use in a wall assembly. The sheet metal framing
member comprises a U-shaped track section (for receiving a
plurality of studs) connected to a J-shaped retention flange (for
retaining a piece of drywall). The U-shaped track section includes
a first web connected to confronting first and second flanges, and
the J-shaped retention flange includes a second web connected to
the second flange and a third flange. The second flange confronts
and is between the third flange and the first flange, and the
height of the second flange is greater than the height of the first
flange, while the first web is parallel to the second web.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of priority to U.S.
Provisional Application No. 62/259,388 filed on Nov. 24, 2015,
which application is incorporated herein by reference in its
entireties for all purposes.
TECHNICAL FIELD
[0002] The present invention relates generally to sheet metal
framing members used in the construction of buildings and, more
particularly, to a sheet metal track framing member having a
J-shaped flange for retaining a piece of drywall.
BACKGROUND OF THE INVENTION
[0003] Metal framing assemblies used to construct commercial and
residential buildings are common in the building construction arts.
These metal framing assemblies are generally constructed from a
plurality of metal framing members including studs, joists,
trusses, and other metal posts and beams formed from sheet metal
and frequently fabricated to have the same general cross-sectional
dimensions as standard wood members used for similar purposes.
Metal framing members are typically constructed by roll-forming 12
to 24 gauge galvanized sheet steel. Although many cross-sectional
shapes are available, the primary shapes used in building
construction are C-shaped studs and U-shaped tracks.
[0004] In the building construction trade, a head-of-wall joint
(also sometimes referred to as a top-of-wall joint) refers to the
linear junction or interface existing between a top section of a
framing/wallboard wall assembly and the ceiling (where the ceiling
may be a next-level floor or corrugated pan roof deck, for
example). Head-of-wall joints often present a serious challenge in
terms of reducing or preventing the spread of smoke and fire during
a building fire.
[0005] There is still a need in the art for new and improved
profiles. The present invention fulfills these needs and provides
for further related advantages.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] Like reference numerals are used to designate like parts and
features throughout the several views of the drawings.
[0007] FIG. 1 is an end view (profile view) of a sheet metal
framing member having a J-shaped retention flange in accordance
with an embodiment of the present invention.
[0008] FIG. 2 is an end view (profile view) of the sheet metal
framing member having a J-shaped retention flange as shown in FIG.
1, but with the "J" retention flange feature highlighted by being
encircled.
[0009] FIG. 3 is an end view (profile view) of a sheet metal
framing member having a J-shaped retention flange having a fire
retardant strip positioned along an outer surface of a flange in
accordance with an embodiment of the present invention, and wherein
the framing member is attached to an overhead framing element
(structural and non-structural).
[0010] FIG. 4 is an end view (profile view) of the sheet metal
framing member having a J-shaped retention flange as shown in FIG.
3, but with the "J" retention flange shown retaining a piece of
drywall (gypsum panel).
[0011] FIG. 5 is an end view (profile view) of the sheet metal
framing member having a J-shaped retention flange as shown in FIGS.
3 and 4, but shown with a second sheet metal framing member having
a J-shaped retention flange positioned on the opposite side of the
overhead framing element (structural and non-structural) and also
retaining the piece of drywall (gypsum panel).
[0012] FIG. 6 is an end view (profile view) of the sheet metal
framing member having a J-shaped retention flange as shown in FIG.

track sections.
[0013] FIG. 7 is another configuration of a wall assembly
comprising a sheet metal framing member having a J-shaped retention
flange in accordance with an embodiment of the present
invention.
[0014] FIG. 8-11 are other views of the present invention.
DISCLOSURE OF THE INVENTION
[0015] Referring now to the drawings wherein like reference
numerals designate identical or corresponding elements, and more
particularly to FIGS. 1-8, the present invention in one embodiment
is directed to a sheet metal framing member 10 having a J-shaped
retention flange 12 useful for holding (retaining) studs and
wallboard within a wall assembly (such as, for example, a shaft
wall assembly). The innovative sheet metal framing member 10 is
made from a continuous piece of sheet metal (such as, for example
roll forming and/or brake pressing operations) and is especially
configured for use in a wall assembly. The sheet metal framing
member 10 comprises a U-shaped track section 14 (for receiving a
plurality of studs 6, 15) connected to a J-shaped retention flange
12 (for retaining a piece of drywall 17). The U-shaped track
section 12 includes a first web 16 connected to confronting first
and second flanges 18, 20, and the J-shaped retention flange 12
includes a second web 22 connected to the second flange and 20 a
third flange 24. As shown. the second flange 20 confronts and is
between the third flange 24 and the first flange 18, and the height
of the second flange 20 is greater than the height of the first
flange 18, while the first web 16 is parallel to the second web
22.
[0016] As also shown, the height of the first flange 18 is greater
than or equal to the height of the third flange 24. In addition,
the width of the first web 16 is greater than the width of the
second web 22.
[0017] In some embodiments and as shown in FIGS. 4-7, the
innovative framing member 10 further comprises a fire retardant
strip 19 positioned along an outer surface of the first flange 18.
The fire retardant strip 19 may be an intumescent material and
preferably extends beyond the web a small distance (- 1/16
inch).
[0018] While the present invention has been described in the
context of the embodiments illustrated and described herein, the
invention may be embodied in other specific ways or in other
specific forms without departing from its spirit or essential
characteristics. Therefore, the described embodiments are to be
considered in all respects as illustrative and not restrictive. The
scope of the invention is, therefore, indicated by the appended
claims rather than by the foregoing descriptions, and all changes
that come within the meaning and range of equivalency of the claims
are to be embraced within their scope.
