Overhang support system for gable roofs
Abstract
This invention provides an overhang support system for gable
roofs which eliminates any need to put a notch in the gable end
truss top chord member. It utilizes a novel unitary connector device
for improved support of overhang structures in a gable roof of the
type including an overhang member, a gable end truss top chord
member, and a first adjacent truss (to the end truss) top chord
member. The rigid connector provides some holes for nailing to an
intermediate support member, situated between the first adjacent
truss top chord member and the gable end truss top chord member, or,
optionally, in one preferred embodiment, if no intermediate support
member is used, these holes are used for nailing to an overhang
support member; and it provides some holes for nailing to an
overhang support member, situated between the gable end truss top
chord member and the overhang member; and also holes for nailing to
the gable end truss top chord member. The connector is
channel-shaped to fit snugly over, e.g., the overhang support
member; and the connector enhances the strength of cantilever
support of the overhang support member.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to providing an overhang support system for
gable roofs. More particularly, this invention concerns such a
system utilizing a novel connector device for improved cantilever
support of overhang structures as well as improved resistance
against uplift forces, such as wind.
2. Description of the Prior Art
The typical prior art systems for providing an overhang support
system for gable roofs are described and illustrated (see FIG. 1 and
FIG. 2) in connection with the detailed description hereinafter of
this invention. Such prior-art systems, as further hereinafter
particularized, either fail to provide strong enough support for
gable roof overhang members or create new structural problems in
providing such support. For example, one typical method used to
provide support for gable roof overhang members is to provide a
plurality of unitary overhang support members extending from the top
chord of the first adjacent roof truss, bisecting the gable end
truss, and continuing outward to the overhang members. To provide a
roof with a uniform slope, it is necessary to cut notches in either
the gable end truss, the overhang support members, or both at the
point where the unitary overhang support members bisect the gable
end truss. Requiring the notching of one or more members is not only
difficult, costly and time consuming, it also produces stress
concentration sites at the notch points thereby decreasing the
effective load bearing strength of the notched members.
Applicant is aware of other prior art attempts to make more rigid
the connection points of various structural members. For example,
U.S. Pat. No. 5,150,982 issued to Gilb discloses a deck post tie for
use in resisting overturning bending moments produced in an upright
structural member. To provide structural resistance to possible
bending moments, the Gilb apparatus teaches a tie in which the top
surface is not flush with the adjacent surface of the support
member, but rather has a gradual slope which increases in the
direction of maximum bending moment (e.g., bottom of upright support
member). Though the Gilb apparatus may be adequate for its intended
purpose, it would be inadequate for the purposes of the present
disclosure because the sloped top surface, though necessary to
counteract bending moments when used in accordance with the Gilb
disclosure, would produce a roof having a non-uniform slope. Thus,
it is believed by the applicant that the prior art cited herein will
not accomplish the purpose of the present invention.
OBJECTS OF THE INVENTION
A primary object of the present invention is to fulfill the need for
strong support of gable roof overhang members, without thereby
creating new structural problems, by the provision of an improved
overhang support system according to the present invention. A
further primary object of the present invention is to provide such
an improved system utilizing a unitary connector body of the present
invention. A further primary object of the present invention is to
provide such a system and body which are efficient, inexpensive, and
handy. Other objects of this invention will become apparent with
reference to the following invention descriptions.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT AND THE BEST MODE OF
PRACTICE
Shown in perspective views, in FIGS. 1 and 2, are portions of
buildings 20 with prior-art typical roofs 21, in the final stages of
construction. The roofs 21 are of conventional and common
construction, with sloping sides 22 joining at a central elevated
ridge 23. The roofs 21 are typical wood construction, utilizing
standard trusses 24, sheathed with plywood panels 25, and providing
conventional overhang members 26 which extend outward beyond the
walls 27. At the gable ends 30 of the roof 21 are the gable overhang
panels 31 incorporating a fascia 32 on the outward ends. The primary
structural supporting means at each gable overhang panel 31 is the
gable end truss 33, which is the truss supported by an exterior wall
27 and the truss furthest outward at the gable end 30 of the roof
21. To support the gable overhang panels 31 and provide attachment
for the fascia 32, additional interconnecting support structure
between the gable end truss 33 and the fascia 32 is required.
Without additional support structure, for example, the plywood
panels 25 remain cantilevered and unsupported from the gable end
truss 33 outward. With weight from the final roofing coatings and
coverings, an unsupported overhang member 26 is not suitable to
withstand the elements of weather and normal use.
Referring now solely to FIG. 1, a common system for providing
overhang support for the gable ends 30 of a roof 21 is illustrated.
Overhang support members 34 are provided from the top chord 41 of
the gable end truss 33 outward and are the attachment locations for
the overhang members 26 supporting the fascia 32 and the plywood
panels 25 in the overhang areas. Overhang support members 34 would,
for example, commonly be wood 2.times.4's or 2.times.6's or even
larger (being as a group hereinafter called 2.times.'s), with inward
ends 35 abutted against the outer surface 36 of the gable end truss
33, and nailed in place. These overhang support members 34 in the
system of FIG. 1 do provide some strength and integrity to the
overhang members 26, but fail to provide sufficient structural ties
to the remainder of the roof 21. In essence, the roof 21 can bend at
the point of the gable end truss 33, allowing the overhang members
26 (with the gable overhang panels 31 with the fascia 32) and
overhang support members 34 to droop downward. This bending or
drooping may be in connection with twisting of the gable end truss
33 and/or separation of the nailed connections of the overhang
support members 34 to the gable end truss 33, which separation would
also permit undesired uplifting of the overhang members, as by wind.
If the overhang support members 34 were to be further extended
inward into the roof structure, past the gable end truss 33, and
tieing into the first adjacent roof truss 37 (to the gable end truss
33), drooping of the overhang members 26 can be minimized or
eliminated. This method of construction is illustrated in FIG. 2 and
is commonly used in roof construction. Extended overhang supports 40
extend from the top chord 43 of the first adjacent roof truss 37 to
the gable end truss 33 and outward to the overhang members 26. The
twisting forces acting on the gable end truss 33 are thereby
minimized or eliminated and the overhang members 26 receive greater
structural support. The extended roof supports 40 are butted and
nailed to the top chord 43 of the first adjacent roof truss 37, but
as they extend outward to overhang members 26, they pass over and
are supported by the gable end truss 33, but they spatially
interfere with the top of the top chord 41 of the gable end truss
33. To accommodate this interference with the extended roof supports
40, the top chord 41 of the gable end truss 33 is cut into, forming
a notch 42 at each point where the extended roof supports 40 are
located. The extended roof supports 40 may then extend unobstructed
from the first adjacent roof truss 37 outward to the overhang
members 26. Although the gable overhang panels 31 now receive
improved structural support, new problems are encountered. The
notches 42 cut deeply into the top chord 41 of the gable end truss
33, greatly reducing its strength. If the top chord 41 and extended
roof supports 40 are both 2.times.4's, and the extended roof
supports 40 are positioned on their sides for minimum notch 42 depth
requirements, the notch 42 still must be cut about half way through
the height of the top chord 41 of the gable end truss 33. Cutting
notch 42 into the top chord 41 of the gable end truss 33 is also
difficult, costly and time consuming; and it is no solution to the
wind-uplift problem.
As a solution to the problems encountered with the existing art of
roof gable overhang construction as discussed with FIGS. 1 and 2,
the preferred embodiment of the overhang support system for roof
trusses of the present invention, utilizing a novel connecting
device, unitary connector body 45, is illustrated in FIG. 3. A
portion of a roof 21, including an overhang member 26, gable end
truss 33 and first adjacent roof truss 37 are shown in perspective.
As hereinafter more particularly described, unitary connector body
45 and its two other longitudinally-supporting members may be
sometimes referred to together herein as extended roof support 40,
which connects overhang member 26, gable end truss 33, and first
adjacent roof truss 37, tieing them together in a structurally sound
manner. For purposes of this illustration, all members shown are
wood 2.times.4's (although, as stated, 2.times.'s may be used). It
is noted that, in the system of FIG. 3, the top chord 41 of the
gable end truss 33 is a continuous single unitary piece without any
notching for the extended roof supports 40.
Each extended roof support 40 in the system of FIG. 3 consists of
three components, an intermediate support member 46, an overhang
support member 47, and a unitary connector body 45. The intermediate
support member 46 is butted to, and nailed to the first adjacent
roof truss 37 at the inner joint 48. Likewise, the overhang member
26 is positioned to and nailed to the overhang support member 47 at
the outer joint 51. The preferred embodiment of the unitary
connector body 45 provides, as illustrated and described herein,
connection means for connecting to the unitary connector body 45,
the intermediate support member 46, the overhang support member 47,
and the gable end truss 33 (at its top chord 41). Each connection of
the unitary connector body 45 to these other components is made at
each location 52 of the gable end truss 33. The unitary connector
body 45 is preferably formed of galvanized coated steel, is shaped
to snugly fit and locate the wood components (preferably the "2"
edges of the 2.times. wood components) of the connection at location
52, and further provides holes 66 (see FIG. 4) for nailing locations
to retain the components, all as shown and described herein. The
completed connection at location 52 is structurally sound,
permanent, and provides for a strong and efficient gable overhang
support system.
A perspective view of the unitary connector body 45 is shown in FIG.
4. Unitary connector body 45, a channel-shaped member, is preferably
stamped and formed of galvanized coated steel of about 18 gage, or
thicker, and of the configuration illustrated. The channel 53,
providing channel means for fitting snugly over such intermediate
support member and such overhang support member, is about 133/4"
long and includes a planar longitudinal top horizontal surface 54.
Surface 54 in this invention embodies, as shown, a planar portion
constructed and arranged for situation adjacent a plane of an upper
side of gable end truss top chord member 41 and is elongated in a
direction from the connection of unitary connection body 45 to
intermediate support member 46 to the body 45 connection with
overhang support member 47. Extending downward perpendicular from
the longitudinal edges of the horizontal surface 54 are two vertical
sides 55 about 11/2" in depth. The width between the vertical sides
55, on the interior of the channel 53 is about 11/2" to fit snugly
over the narrow "2" dimension of a 2.times.4 or other 2.times. size.
About midway along the length of the unitary connector body 45, on
each vertical side 55, is an opening 56, about 11/2" wide, and
extending from the top horizontal surface 54 downward vertically the
full height of the vertical sides 55. The two openings 56 are
located exactly opposite each other, (once again, sized to fit
snugly over top chord 41, the narrow dimension of a 2.times.4 or
other 2.times. size).
Two longitudinal ribs 60 rise, about centrally, as illustrated, from
the elongated planar portion embodied by top horizontal surface 54,
to strengthen the channel 53 against downward bending through the
area weakened by the openings 56 on the vertical sides 55. Thus,
ribs 60 embody strengthening means for enhancing the structural
support against bending of such planar portion of such unitary
connector body. One end of the channel 53 is stamped with indicia
61, identifying that end as the fascia (barge) end 62. At each
opening 56 on the vertical sides 55, the greater portion of the
material from each opening 56 is bent outward at 90 degrees on a
vertical bend line 63, on the side of each opening 56 nearest the
indica 61 to form a nailing wing 64, which is also useful for
positioning and cantilever-support assistance, and thus embodies in
this invention a first connector positioning means for abutting
gable end truss top chord member 41 for providing enhanced
cantilever support for overhang support member 47. A minor portion
of the material from each opening 56 extends outward (unbent) from
each side of the top horizontal surface 54, above the opening 56,
and forms a nailing wing 65. At one location on each nailing wing 64
and each nailing wing 65 and at six locations on each vertical side
55 are nailing holes 66, embodying in the present invention hole
means in unitary connector body 45 for receiving attaching units
(embodied herein by nails 67). All 90-degree corners of the unitary
connector body 45 are slightly trimmed off at 45 degrees, as shown,
to remove sharp damaging metal corners.
The use of the features of the unitary connector body 45 and the
overhang support system of the present invention are further
described as illustrated in FIGS. 5-7. FIG. 5, which is a view
through the section 5--5 of FIG. 3, is an elevation end view of the
unitary connector body 45 from the fascia (barge) end 62. The
unitary connector body 45 is installed on top of the top chord 41 of
the gable end truss 33 with the longitudinal run of the channel 53
perpendicular to the longitudinal run of the top chord 41 within the
openings 56 (not shown) of the vertical sides 55. The nailing wings
65 are nailed to the top of the top chord 41, and the nailing wings
64 are nailed to the front of the top chord 41 with nails 67, all as
shown in the drawings. The overhang support member 47 of the
extended roof support 40 is inserted into the fascia (barge end) 62
of the channel 53 of the unitary connector body 45 and positioned
tightly against the top chord 41 and then secured into the channel
53 with nails 71. Likewise, although not shown in this view, the
intermediate support member 46 of the extended roof support 40 is
installed at the opposite end of the unitary connector body 45.
Thus, the present invention provides a method of providing improved
support to an overhang support member 47 extending outward from a
gable end truss top chord member 41 to support an overhang member
26, comprising the steps of: attaching an intermediate support
member 46 between such gable end truss top chord member 41 and the
first adjacent truss top chord member 43; attaching such
intermediate support member 46 and such gable end truss top chord
member 41 to a rigid unitary connector body 45; attaching such
overhang support member 47 to such rigid unitary connector body 45
and abutting such gable end truss top chord member 41; and attaching
such overhang member 26 to such overhang support member 47; such
rigid unitary connector body 45 being constructed and arranged to
enhance the strength of cantilever support of such overhang support
member 47. And it provides improved wind-uplift support.
FIG. 6, which is a view through the section 6--6 of FIG. 3, shows a
side elevation view of the unitary connector body 45 joining the
intermediate support member 46 and overhang support member 47 to the
top chord 41 of the gable end truss 33. The openings 56 in the
vertical sides 55 fit over the top chord 41 with nails 67 through
nailing wings 64 and nailing wings 65 securing the unitary connector
body 45 in place. Intermediate support member 46 and overhang
support member 47 are fitted into the channel 53 of the unitary
connector body 45 until tight against the top chord 41, and secured
with nails 71. Nailing holes 66 through each vertical side 55 of
unitary connector body 45 are staggered, as shown, to prevent the
nails entering each side of the intermediate support member 46 and
overhang support member 47 from splitting the wood, thereby
embodying offset means for providing nailing locations for
minimizing structural harm to intermediate support member 46 and
overhang support member 47.
In FIG. 7 is shown a top plan view of the connection location 52,
with intermediate support member 46 and overhang support member 47
of extended roof support 40 secured at 90 degrees to the top chord
41 of gable end truss 33 with unitary connector body 45. Ribs 60 on
the top horizontal surface 54 of the unitary connector body 45
provide added rigidity against bending through the location 52.
Nailing wings 64 are located on the front side of the gable end
truss 33, facing the direction of the fascia.
FIG. 8 is a plan view of the unitary connector body 45 in its flat
form during its preferred method of manufacture, in well known ways,
after all shearing, notching, punching and stamping, but prior to
bending into its final shape. Dotted lines represent bend lines 63
where nailing wings 64 will be bent upward 90 degrees. Bend lines 72
show locations of downward 90-degree bending of the sides which will
form the described channel shape. Thus, it is seen that unitary
connector body 45 comprises: first connection means (embodied by,
e.g., the specific nail-hole 66 connections structures, etc., of
FIGS. 3 and 6) for connecting intermediate support member 46,
situated between first adjacent truss top chord member 43 and gable
end truss top chord member 41, to unitary connector body 45; second
connection means (embodied by, e.g., the specific nail-hole 66
connections structures, etc., as shown in FIGS. 3 and 6) for
connecting overhang support member 47, situated between gable end
truss top chord member 41 and overhang member 26, to unitary
connector body 45; and third connection means (embodied by, e.g.,
the specific nail-hole 66 connections structures, etc., of FIGS. 3
and 6) for connecting gable end truss top chord member 41 to unitary
connector body 45; unitary connector body 45 being constructed and
arranged to enhance, when connected, the strength of cantilever
support of overhang support member 47, as well as enhancing uplift
support.
FIGS. 9 and 10 illustrate an alternate construction of the preferred
embodiment of the unitary connector body 45. In FIG. 9, a top plan
view of a portion of the unitary connector body 45 is shown prior to
bending into its final shape. An additional small tab 73 is
incorporated at each opening 56 in the vertical sides 55. At bend
lines 74, the tabs 73 are bent upward 90 degrees the same as nailing
wings 64 are bent upward at 90 degrees at bend lines 63. In FIG. 10,
a perspective view illustrates the central portion of the unitary
connector body 45 incorporating the small tabs 73. The spacing
between the inside facing surfaces of nailing wings 64 and tabs 73
is about 11/2", providing for a close fit to the 2.times. of the
gable end truss 33. Tabs 73 provide for a flat surface contact to
the gable end truss 33, thus preventing any possible cutting into
the wood and resulting loosening of the location 52. In this
invention, tabs 73 also embody a second connector positioning means
for abutting gable end truss top chord member 41 for providing
positioning support for unitary connector body 45.
FIG. 11 is a perspective view of a connection location 52 of an
intermediate support member 46 and an overhang support member 47 to
the top chord 41 of a gable end truss 33, using horizontal
2.times.4's for the intermediate support member 46 and overhang
support member 47. This connection utilizes an alternate embodiment
77 of unitary connector body 45 which allows for members 46 and 47
to be installed horizontally. The channel 53 of unitary connector
body 45 is about 31/2 inches wide for mating to the
horizontally-installed 2.times.4 members. An oblong hole 78 is
incorporated near each end of the top horizontal surface 54 to allow
nailing of the final plywood panels 25 (not shown) to the extended
roof support 40 in the area of the unitary connector body 45. To
illustrate the use of a unitary connector body 45 to make up a
connection location 52 as compared to the notching used with the
prior art method shown in FIG. 2, a notch 42 is shown by dotted
lines.
FIG. 12 shows the connection location 52 in elevation view through
the section 12--12 of FIG. 11. Nails 71 through the vertical sides
55 of the unitary connector body 45 of the alternate embodiment 77
may be placed in line with each other as the wider channel 53
usually prevents splitting of the wood.
FIG. 13 is a plan view of the unitary connector body 45 of the
alternate embodiment 77 in its flat form after all shearing,
notching, punching, and stamping, but prior to bending into its
final shape. An additional reinforcing rib 60 (compared to the
embodiment of FIG. 3) is utilized due to the increased width of the
top horizontal surface 54. Oblong holes 78, as mentioned, are
provided to allow nailing of the final plywood panels 25. Also, due
to the increased width of the top horizontal surface 54, nailing
holes 66 are incorporated on the top horizontal surface 54 and
additional nailing wings are not required.
Illustrated in FIG. 14 is a perspective view of a portion of roof
21, showing the overhang member 26, the gable end truss 33, and the
first adjacent roof truss 37, with these members being structurally
tied together with extended roof supports 40. An alternate method of
construction is utilized with the incorporation of the third
alternate embodiment 80 of the unitary connector body 45 included
within the extended roof supports 40. This unitary connector body 45
provides for the intermediate support member 46, spanning between
the first adjacent roof truss 37 and the top chord 41 of the gable
end truss 33, to be positioned more-horizontally (as shown in the
FIGS., particularly FIG. 14), whereas the overhang support member 47
is positioned on edge more-vertically (as shown in the FIGS.,
particularly FIG. 14) as it extends outward from the gable end truss
33 to support the overhang member 26. As previously described with
prior embodiments, the overhang support member 47 and the top chord
41 of the gable end truss 33, to which the unitary connector body 45
is fitted, are shown as 2.times.4's, although 2.times.'s may be
used. The intermediate support member 46, oriented
more-horizontally, may be of any desired width of lumber,
2.times.'s, 4.times.'s, etc. As with prior embodiments, the
intermediate support member 46 is butted to and nailed to the first
adjacent roof truss 37 at the inner joint 48. Likewise, the overhang
member 26 is positioned to and nailed to the overhang support member
47 at the outer joint 51. The third alternate embodiment 80 of the
unitary connector body 45 incorporates nailing holes for nailing to
the intermediate support member 46, the overhang support member 47,
and the top chord 41 of the gable end truss 33 at their
interconnection at location 52 of the gable end truss 33. This
provides for an efficient and strong joint.
A perspective view of the third alternate embodiment 80 of the
unitary connector body 45 is shown in FIG. 15. The unitary connector
body 45 is preferably stamped and formed of galvanized coated steel,
with material thickness of approximately 18 gage, or thicker, and of
the configuration illustrated. The unitary connector body 45
incorporates a channel 53, providing, in the present embodiment, a
first channel means into which the overhang support member 47 may be
snugly fitted. Additionally, the unitary connector body 45
incorporates a planar longitudinal top more-horizontal surface 54,
as shown, oriented in a longitudinal direction aligned with
intermediate support member 46 and overhang support member 47, for
mating with the top planar horizontal surfaces of the intermediate
support member 46, overhang support member 47, and the top chord 41
of the gable end truss 33, at the location 52 of the joining of
these members. Nailing holes 66 through surface 54 provide nailing
locations for nailing of the unitary connector body 45 to the top
planar more-horizontal surface of the intermediate support member
46, overhang support member 47, and the top chord 41 of the gable
end truss 33. Extending downward perpendicular from each of the
outward longitudinal edges 57 and 58 of the more-horizontal surface
54 are two more-vertical sides 55, as shown, preferably extending
downward about 31/4", and forming channel 53, as shown. This
resultant channel 53 is preferably about 4" long and about 11/2" in
interior width for a snug interface with the narrow "2" dimension of
a 2.times.4 or other 2.times. size. These preferred increased sizes
(over those of other embodiments) also enhance wind-uplift
resistance. At the inboard end of each more-vertical side 55 is a
nailing wing 64, extending outward at about 90 degrees from each
more-vertical side 55, as shown. The two opposing nailing wings 64
form a flat more vertical planar surface, at a right angle to the
channel 53, and include nailing holes 66 for secure nailing to the
outward face of the gable end truss top chord 41, as shown. The
inward portion 81 of the surface 54 is sized to extend inward over
the intermediate support member 46 approximately 31/4" and
incorporates an increased width, as shown, of about 31/4".
FIG. 16, which is a view through the section 16--16 of FIG. 14,
shows a side elevation view of the third alternate embodiment 80 of
the unitary connector body 45, joining the intermediate support
member 46 and overhang support member 47 to the top chord 41 of the
gable end truss 33. The underside of the top surface 54 of the
unitary connector body 45 rests atop the top chord 41 with nailing
wings 64 contacting the outward more-vertical face of the top chord
41. Nails 67 secure the unitary connector body 45 to the top chord
41. An intermediate support member 46 is fitted to the underside of
the extending inward portion 81 of the surface 54, butted against
the top chord 41 and nailed in place with nails 82 through the
nailing holes 66 of the surface 54. The overhang support member 47
is fitted into the channel 53 of the unitary connector body 45 until
tight against the top chord 41, and secured with nails 71 through
the nailing holes 66 of the surface 54 and both sides 55.
FIG. 17 is a top plan view of the third alternate embodiment 80 of
the unitary connector body 45 in its flat form during manufacture
and after all shearing, notching, and punching operations, but prior
to bending into its final shape. Bend lines 63, represented by
dotted lines, show where nailing wings 64 will be bent upward 90
degrees from the flat form, and result in perpendicularly outwardly
extending and opposing nailing wings 64. Bend lines 72 show
locations of downward 90 degree bending of the sides 55 which will
form the described channel shape. Rend line 83 represents the
location of an optional 90 degree bend that is described in FIGS. 18
and 19.
FIGS. 18 and 19 illustrate an alternate form and usage of the third
alternate embodiment 80 of the unitary connector body 45. This
alternate form may be produced at the time of manufacture of the
unitary connector body 45 or it may be accomplished in the field, at
the time of usage. As previously described, the third alternate
embodiment 80 of the unitary connector body 45 completes the
extended roof supports 40 by providing locating and attachment means
for securing the intermediate support member 46 and overhang support
member 47 to the top chord 41 of the gable end truss 33. With
conventional roof framing and roof overhang construction, as
described in the prior art of FIG. 1, an overhang support member 47
(or 34) may be used without the added strength benefit of an
intermediate support member 46. If the top chord 41 of the gable end
truss 33 is rigid, stable and of ample strength to support the
overhang member 26 and related weights, the remaining difficulty is
providing a worthy attachment of the overhang support member 47 (or
34) to the top chord 41. As previously described, loosening or
separation of the nailed connections of the overhang support member
47 (or 34) from the gable end truss 33 could result in structural
failure. To provide a strong and permanent attachment of the
overhang support member 47 (or 34) to the top chord 41 the third
alternate embodiment 80 of the unitary connector body 45, in an
altered form, may be used.
In the perspective view of FIG. 18, the alternate form 84 of the
third alternate embodiment 80 is shown with the enlarged inward
portion 81 of the surface 54 bent downward at about 90 degrees from
surface 54, as shown. This bend is located at bend line 83, also
shown in FIG. 17. The resulting shape of the unitary connector body
45 provides an opening 56, approximately 11/2" wide, for placement
of the unitary connector body 45 onto the top chord 41.
The alternate form 84 of the third alternate embodiment 80 of the
unitary connector body 45 is shown installed, in the perspective
view of FIG. 19. The unitary connector body 45 is nailed to the
outward face of the top chord 41 with nails 67 through holes in
nailing wings 64 and to the top surface of the top chord 41 with
nail 67 through hole in the top surface 54, as previously described.
In addition, the unitary connector body 45 is prevented from being
pulled from, or loosened from, the top chord 41 with the
incorporation of the downward bent inward portion 81 of the surface
54 wrapped and nailed with nails 67 to the inward face of the top
chord 41, as shown. When the overhang support member 47 is secured
within the channel 53 of the unitary connector body 45, a rigid,
permanent joint is obtained. As stated previously, this downward
bend of the inward portion 81 of the surface 54 at bend line 83
could be furnished by the manufacturer of the unitary connector body
45, or bent at the job site by the contractor. If bent by the
contractor, the bend would be made with a hammer after the connector
body 45 has been nailed to the top chord 41 at the top and at the
nailing wings 64. Thus, in a preferred embodiment, as described
herein, bend line 83 (or the optional bend illustrated), along with
inward portion 81 of surface 54 comprises first connection means for
use, optionally, by a user, (1) for connecting an intermediate
support member, situated between the first adjacent truss top chord
member and the gable end truss top chord member, to the unitary
connector body, or (2) for connecting the gable end truss top chord
member to the unitary connector body. Also, in a preferred
embodiment, as described herein and shown herein, the first
connection means comprises a substantially-flat bendable portion
constructed and arranged in such manner as to provide, when the
described/shown bendable portion is not bent, an attachment means
for connecting an intermediate support member, situated between the
first adjacent truss top chord member and the gable end truss top
chord member, to the unitary connector body, and, when such bendable
portion is bent, at about 90 degrees, an attachment means for
connecting the gable end truss top chord member to the unitary
connector body.
With reference now to FIGS. 20-22, a fourth alternate preferred
embodiment of the unitary connector body 45, hereinafter designated
by reference numeral 90, will be disclosed. Shown in FIG. 20 is a
top plan view of the fourth alternate embodiment 90 of the unitary
connector body 45 in its flat form during manufacture and after all
shearing, notching, and punching operations, but prior to bending
into its final shape. Bend lines 91, represented by dotted lines,
show where each of the respective nailing wings 92 and 93 will be
bent upward 90 degrees from the flat form, and result in
perpendicularly outwardly extending and opposing nailing wings 92
and 93. Bend lines 95 show locations of downward 90 degree bending
of the side walls 96 which will form the hereinafter described
channel shape. Bisecting bend lines 91 are a plurality of outwardly
protruding strengthening ribs 97, formed in accordance with a
typical metal forming process, for providing the unitary connector
body 45 with enhanced lateral support adjacent bend lines 91 when
the unitary connector body 45 is in use. The unitary connector body
45 is also provided with a plurality of nailing holes 66 which are
utilized to facilitate attachment of the unitary connector body 45
to the various members comprising the overhang support. As shown, it
is preferred that each nailing hole 66 be offset (i.e., staggered to
be out of line) from the corresponding nailing hole 66 so as to
prevent splitting of the individual wooden members.
FIGS. 21 and 22 illustrate, respectively, a preferred field-ready
form and usage of the fourth alternate embodiment 90 of the unitary
connector body 45. In a manner substantially as described previously
with respect to the aforementioned embodiments, the fourth alternate
embodiment 90 of the unitary connector body 45 completes the
extended roof supports 40 by providing locating and attachment means
for securing the intermediate support member 46 and overhang support
member 47 to the top chord 41 of the gable end truss 33 without the
need for performing the time-consuming task (and
construction-weakening procedure) of notching one or more of the
abovementioned members. Shown is a unitary connector body 45
comprising a first channel portion 100 (embodying herein first
channel means for fitting snugly over such overhang support member)
and a second channel portion 101 (embodying herein second channel
means for fitting snugly over such intermediate support member),
each preferably having a length of about 4 inches.
Each respective channel portion 100 and 101 comprises two opposing
side walls 96 separated by a preferred distance of approximately
11/2 inches and extending downward from the planar top portion 102
for a distance of preferably 31/4 inches. To provide enhanced
positioning and lateral support, a pair of first nailing wings 92
(embodying herein first connector positioning means for abutting
such gable end truss top chord member for providing enhanced
cantilever support for such overhang support member) are provided
adjacent the inner end 106 of each side wall 96 of the first channel
portion 100. Likewise, a pair of second nailing wings 93 (embodying
herein second connector positioning means for abutting such gable
end truss top chord member for providing positioning support for
such unitary connector body) are provided adjacent the inner end 106
of each side wall 96 of the second channel portion 101.
It is preferred that each of the respective pairs of nailing wings
92 and 93 be separated by a preferred distance of approximately 11/2
inch so as to provided a snug interface with the "2" dimension of a
2.times.4 or other "2.times." size. As shown, the strengthening ribs
97 preferably are integral to the unitary connector body 45 and
extend from each respective nailing wing 92 and 93 to an adjacent
side wall 96. The strengthening ribs 97 embody herein side
strengthening means, adjoining such first connector positioning
means and such second connector positioning means, for enhancing the
structural support against lateral bending of such unitary connector
body. As used herein, "lateral bending" refers to the tendency of
the unitary connector body 45 to bend in the direction of a
resultant force applied normal to a side wall 96 when the unitary
connector body 45 is incorporated into the roof structure in the
manner illustrated and described with respect to FIG. 22.
FIG. 22 is a perspective view of a connection location 52 of an
intermediate support member 46 and an overhang support member 47 to
the top chord 41 of a gable end truss 33, using 2.times.4's for the
intermediate support member 46 and overhang support member 47. As
will be appreciated by those skilled in the relevant art, the
unitary connector body 45 comprises a symmetric structure (with
respect to both the longitudinal and transverse axis of the unitary
connector body 45) in which the first and second channel portion 100
and 101 may be attached to either the intermediate support member 46
or overhang support member 47, therefore providing for quick and
simple installation, without possibility of direction confusion by
installers. This arrangement embodies herein an arrangement wherein
such first and second channel portions 100 and 101 are
longitudinally symmetrical and essentially identical in structure;
and wherein such first and second pairs of nailing wings are
longitudinally symmetrical and essentially identical in structure;
whereby such unitary connector body may be situated with either of
such longitudinal ends facing such overhang member.
As shown, each respective pair of nailing wings 92 and 93 are
structured and arranged for attachment to the adjacent first and
second sides 107 and 108, respectively, of the top chord 41 of a
gable end truss 33. Attachment of the unitary connector body 45 to
the aforementioned members 41, 46, and 47 is by attachment units 71,
preferably nails, which are structured and arranged to engage
nailing holes 66. In the present embodiment, nailing holes 66 embody
a first, second, and third connection means for connecting,
respectively, an intermediate support member, situated between such
first adjacent truss top chord member and such gable end truss top
chord member, to such unitary connector body; an overhang support
member, situated between such gable end truss top chord member and
such overhang member, to such unitary connector body; and such gable
end truss top chord member to such unitary connector body.
Although applicant has described applicant's preferred embodiments
of this invention, it will be understood that the broadest scope of
