Description
FIELD OF THE INVENTION
[0001] The present invention in general relates to an apparatus for
installing and securing panels to a frame and in particular to a
joiner plate or clip designed to improve ease, efficiency, and
accuracy of placement, spacing, and alignment of panels when
creating butt joints between panels during installation.
BACKGROUND OF THE INVENTION
[0002] Frame construction is a quick and efficient method of
constructing inner and outer walls in structures. Frames generally
are formed with vertical members called studs that are joined to
upper and lower horizontal members.
[0003] Traditionally, studs were made of wood, usually 2'.times.4''
or 2''.times.6'' dimensional lumber. In North America, studs are
typically placed 16 inches from each other's center, but sometimes
also at 12 inch or 24 inch intervals. Steel studs are gaining
popularity, especially for non load-bearing walls. Typically,
panels, siding or other types of wall materials and sheeting are
secured to the fame via screws, nails, or other specialty fasteners
to the studs.
[0004] Fiber cement (FC) siding most often includes overlapping
horizontal boards, imitating wooden siding, clapboard and imitation
shingles, or large panels simulating tongue and groove or board and
batten applications. Fiber cement siding is also manufactured in a
sheet form and is used not only as cladding but is also commonly
used as a soffit/eave lining and as a tile underlay on decks and in
bathrooms. Fiber cement siding is not only used as an exterior
siding, it can also be utilized as a substitute for timber fascias
and bargeboards, especially in high fire risk or prone areas.
[0005] Siding or cladding materials, due to the material cost or
manufacturing methods, are often thin and typically brittle or
fragile. The thin nature of siding and cladding materials results
in the siding materials conforming to the planar conditions of the
framing. This can result in building stress into the applied panel.
In addition to fiber cement, thin panels may be formed from
laminated and composite wood materials, and panels formed from
polymer resins. Siding materials can also be formed from steel,
aluminum and ultra violet light resistant polyvinyl chloride.
Despite the fragile nature of the aforementioned siding materials,
attachment studs with widths that typically range from between
11/4-inch to 2-inches provide a very small `target` to match and
align the butt ends of the panels formed from the siding materials.
With thicker, less brittle panels, such as cedar siding, a nail or
screw can be installed at an angle into the stud, minimizing the
problems created by the narrow stud; however, this cannot be done
consistently with thinner and brittle panels. When securing panels
to a stud, if a stud is out of alignment or the panel has been
mis-cut, there is insufficient bearing for the two panels to be
secured to a single stud. The problem is compounded by the thin
nature of the panel and the need for the head of the fastener to be
flush with the surface of the panel, which in some situations
requires the use of a countersunk head screw, typically with
`burrs` or `wings` under the head to bore into the relatively hard
and brittle panel to sink the head flush with the panel surface.
The boring weakens the panel at a critical point since the butt
edge attachment is very close to the edge.
[0006] The problems associated with the thin and brittle nature of
certain panels are compounded when attached to a series of studs in
a frame that are not planer. When a stud is not planer to panel,
there is additional stress as two adjoining panel members are
forced into alignment, which creates stress at both panel edges of
the adjoined panels. Furthermore, even if a stud is planer to the
outer face, the face of the stud can be damaged creating a point of
attachment that is out of plane. By loading the end of the panel
and drawing the panel out of plane, the panel will, over time,
likely crack due to the loads created by pushing or pulling the
panel to the misaligned stud. If the butt end of the panel is
supported by the stud by only a fraction of an inch (a common
occurrence) the nail or screw must be installed at an angle,
creating further stress on the panel and resulting in cracking.
Where wood studs are used, fasteners may be installed at angles to
compensate for misalignment. However, for studs that are steel or
made of composite materials, fasteners must enter perpendicular to
the point of attachment to allow the fastener to drill or penetrate
the substrate material.
[0007] Finally, to accommodate for material expansion, panel
manufacturers often require gapping of the panels of approximately
1/16-inch or moderate contact of the edges, achieving such gapping
is time consuming and labor intensive for installers. The expansion
gap between panels further reduces the area on a panel for
attachment to a stud, which creates greater problems achieving an
adequate surface for attachment. For a perfect `marriage` of the
butt ends, the panel ends must be cut perfectly at a ninety degree
angle in the field, which is not always achieved, creating a gap
between the two panel edges, again reducing the target area of
attachment for at least two panels on a single stud. The reduced
area available for attachment requires screw head sizes that must
be smaller to minimize the area of `boring` into the panel surface
to set the screw flush. Since the screw must be a minimum distance
offset from the panel edge, the size of the screw head must remain
small. Typical screw head sizes are 0.330 to 0.450-inches.
[0008] Thus, there exists a need for a joiner plate or clip that
assists in installing and securing panels to a frame and the
improves ease, efficiency, and accuracy of placement, spacing, and
alignment of panels when creating butt joints and required gapping
during installation. There also exists a need for a joiner clip
capable of securing panels to a stud without weakening or
compromising the panels.
SUMMARY OF THE INVENTION
[0009] A joiner clip for securing panels to a substrate is provided
that includes a sheet of material that has a first portion and a
second portion along with a first face and a second face. The sheet
of material is planar or slightly curved and capable to flexing to
a planar configuration. A first pointed anchoring cleat is located
in the first portion of the sheet on the first face. A second
pointed anchoring cleat is located in the second portion of the
sheet on the first face. The first face also includes a spaced
guide that is positioned between the first portion and the second
portion of the sheet. A mounting hole is formed through the sheet
and is positioned colinear with the spacer guide.
[0010] A construction unit is also provided with panels of material
secured by the anchoring cleats and spaced apart by the spacer
guide of such a joiner clip. The joiner clip and panels are secured
to a vertical stud substrate by a fastener that is received by the
joiner clip from the second face and that passes through the joiner
clip into the stud substrate. A joint is readily formed between two
secured panels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] The present invention has utility as a joiner clip to form a
construction unit that assists in installing and securing panels to
a frame and is designed to improve ease, efficiency, and accuracy
of placement, spacing, and alignment of panels when creating butt
joints during installation while also protecting the panels from
being weakened or compromised by the fastener. The joiner clip of
the present invention creates a larger bearing surface at the
critical joint connection between two panels, thereby increasing
wind load resistance in the areas of the panels that typically fail
when held in place by prior art solutions such as screws alone. As
used herein, the terms "joiner plate" and "joiner clip" are used
synonymously. Embodiments of the inventive joiner plate or clip
increase speed in panel or siding installation by minimizing
re-cutting due to variations in studs and provides for an accurate
and consistent spacing between panels during installation. The
inventive joiner plate also reduces the number of fasteners needed
to secure multiple panels to a stud, which reduces overall material
costs and installation time.
[0019] In certain embodiments, a rainscreen batten for creating a
water-resistant barrier and for spacing the panels from the
underlying stud in a non-planar orientation is positioned between
the vertical stud and the panels secured thereto. Embodiments of
the inventive joiner plate may be used for substrates such as wood,
metal, alloy, and steel studs.
[0020] It is to be understood that in instances where a range of
values are provided that the range is intended to encompass not
only the end point values of the range but also intermediate values
of the range as explicitly being included within the range and
varying by the last significant figure of the range. By way of
example, a recited range of from 1 to 4 is intended to include 1-2,
1-3, 2-4, 3-4, and 1-4.
[0021] Embodiments of the on-stud attachment joiner plate or clip
provide for even support of panels with a broad attachment base.
The broad attachment base allows for a reduction in the number of
joiner plates or hangers for a given length of panel, thereby
requiring less labor and installation time. The broad attachment
base provided by embodiments of the inventive joiner, in contrast
to the thinner attachment surface of a traditional stud, allows for
an increased screw head size (versus traditional sizes in the range
of 0.330 to 0.450-inches). The larger screw head creates greater
holding power (rupture over the panel) and a greater wind load
resistance with a single fastener. The joiner clip of the present
disclosure accordingly only requires the use of a single fastener
to secure the ends of two separate panels, whereas prior art
solutions required the use of a separate screw for each end of a
panel. Accordingly, the number of screws required to secure the
same number of panels is reduced by half when using the joiner clip
of the present disclosure. The reduction in the number of screw
fasteners contributes to less potential damage to the panel and
saves time and labor with less fastening. The inventive joiner clip
also provides a significant performance increase in terms of
traction. For example, using an inventive joiner clip to secure a
7.25 inch wide panel to a stud and subjecting the panel to an e-330
test, the ultimate load is 148 psf versus the ultimate load of 126
psf for the same panel secured to a stud at its edge using a nail.
Accordingly, the inventive joiner clip provides at least a 17%
increase in performance.
[0022] The inventive joiner plate acting as an attachment or
bearing plate for panels can be attached to a stud with one or two
screws, depending on the size of the panels and the wind load
requirements for the project. From an aesthetic point of view, the
larger area of attachment also allows the installer to create an
even pattern of joiner plate attachments instead of forcing
fasteners in at the corners that are not pleasing.
[0023] Furthermore, the broad attachment area of the inventive
joiner clip allows for screws or other fasteners to always be
installed perpendicular to the joiner plate steel. The screw will
enter the joiner plate without skidding and will create maximum
holding power while not stressing the panel. Attachment at extreme
edges of the panel that weakens the panel with traditional studs is
eliminated with the inventive joiner.
[0024] The panel is properly aligned, vertically, by the spacer
guide and anchoring cleats. The anchoring cleats properly align the
panels and assist to hold the panels in place prior to attachment
of the joiner clip to the stud. Once the fastener penetrates the
stud, the joiner clip draws the panels to the stud and the joiner
plate to the panels. This assists in reducing stress when a stud is
out of alignment and creates a larger bearing surface at the front
of the panel to create greater support.
[0025] The flat face of the joiner clip creates an excellent
surface to mate the two panel edges. The outer edges and surfaces
of the joined panels will always be in plane, eliminating shadow
lines, voids, and out of plane edges. The joining clip can be
formed in various sizes to address any size lap panel with any
predetermined overlap. The joining plate can be pre-colored to
match pre-painted siding or can be formed from paint grip or
bonderized metal that will easily take paint. The gauge or
thickness of joiner plate can be reduced by adding stiffening ribs
running perpendicular with the studs.
[0026] Embodiments of the joiner clip can adjust to accommodate
minor planar stud deviations in the frame support. The joiner clip
does not need to be perfectly aligned on the stud, since the large
bearing surface creates room for adjustment. The joiner clip can be
offset to compensate for a stud that is spaced or sized
irregularly. The correction of minor stud deviations reduces load
protection and therefore stress on attached panels such as cement
panels. Furthermore, embodiments of the joiner clip are thin enough
to `move` to create a snug connection with panels including fiber
cement, yet strong enough to transfer the load through the fastener
to the steel or wood stud, thereby creating an immediate
correction.
[0027] With reference to the attached figures, an inventive joiner
plate or clip is depicted generally at 10. As shown in FIGS. 1-3,
the joiner plate 10 is generally formed from a sheet of material 12
composed of metal; metal alloys; plastic; fiber reinforced resins
of fiberglass or carbon fiber; or other composite materials. In an
embodiment the joiner plate 10 may be formed from 16 gauge to 20
gauge, G-90 galvanized or galvalume metal, or 16 gauge to 26 gauge
galvanized paintgrip/bonderized for painting of the joiner plate
surface or stainless steel 304 and 316. According to embodiments,
the sheet of material 12 is planar. In various embodiments the
sheet of material 12 is slightly curved in its natural, non-use
state, as shown by the dotted line in FIG. 3B. Such curved sheet 12
joiner clips are configured to flex to a planar configuration when
in use with panels to be joined. As used herein, the term "planar"
means in the form of a plane and includes both sheets 12 that are
permanently planar and those that are curved in a non-use state and
capable of flexing to a planar configuration during use. The joiner
plate 10 includes a first portion 14 and a second portion 16.
According to some embodiments, the first portion 14 and second
portion 16 can be thought of as the right half and the left,
respectively, of the joiner clip 10. The joiner clip 10 shown in
FIG. 1 also includes a first face 18 and an oppositely opposed
second face 19 on the reverse side of the first face 18, which is
therefore not shown in FIG. 1. According to embodiments, both the
first face 18 and the second face 19 are generally planar to allow
smooth planar contact with panels and mounting substrates,
respectively.
[0028] The joiner clip 10 further includes a first anchoring cleat
20 and a second anchoring cleat 22. Both the first anchoring cleat
20 and the second anchoring cleat 22 are disposed on the first face
18, with the first anchoring cleat 20 being within the first
portion 14 and the second anchoring cleat 22 being within the
second portion 16 of the planar sheet 12 of the joiner clip 10.
While each of the first anchoring cleat 20 and a second anchoring
cleat 22 are shown for visual clarity as single cleats, each of the
cleats 20 and 22 can independently include additional cleats that
are displaced horizontally, vertically, or a combination thereof
relative to those depicted in FIG. 1. These duplicate cleats are
not shown for visual clarity, yet provide for increased joinder
strength, compared to that depicted in FIG. 1. It is appreciated
that duplicate cleats of either cleats 20 or 22 can each protrude
to the same extent or a different extent than those depicted in
FIG. 1.
[0029] The first and second anchoring cleats 20, 22 form a first
point and a second point, respectively, on the first face of the
planar sheet 12 of the joiner clip 10. The points are readily
formed by cutting parallel slits and punching the intermediate out
of the basal plane of the sheet 12. According to some embodiments,
the first anchoring cleat 20 is in-line with, or synonymously
referred to herein as colinear with, the second anchoring cleat 22
and the spacer guide 24, as shown in FIG. 1, while in other
embodiments, the anchoring cleats 20, 22 are positioned such that
they are offset linearly from one another. In some embodiments, the
first anchoring cleat 20 and the second anchoring cleat 22 are
equally spaced from a spacer guide 24 (described in further detail
below) as shown in FIG. 1, while in other embodiments one of the
first or second anchoring cleats 20, 22 is spaced farther from the
spacer guide 24 than the other. According to various embodiments,
the first and second anchoring cleats 20, 22 are separate features
that are attached to or passed through the planar sheet 12, for
example nails, hooks, or barbs. In some embodiments, the first
anchoring cleat 20 and the second anchoring cleat 22 are integrally
formed with the planar sheet 12, for example by punching the
anchoring cleats 20, 22 into the planar sheet 12 from the side of
the second face 19 such that the first and second points of the
first and second anchoring cleats protrude from the first face 18
of the planar sheet 12. It is appreciated that while the angular
displacement between the anchoring cleats 20 and 22, a and a' and
the spacer guide is depicted as being perpendicular in FIG. 1,
these angular displacements each vary independently between 0 and
180 degrees and in some embodiments, a is between 70 and 110
degrees.
[0030] The joiner clip 10 also includes a spacer guide 24 disposed
on the first face 18 of the planar sheet 12 of the joiner clip 10.
The spacer guide 24 is positioned on the first face 18 between the
first portion 14 and second portion 16 of the planar sheet 12.
According to some embodiments, the spacer guide 24 is a separate
feature that is attached to the planar sheet 12, while in other
embodiments, the spacer guide 24 is integrally formed with the
planar sheet 12, for example by punching. According to some
embodiments, the spacer guide 24 is oriented perpendicularly to the
first anchoring cleat 20 and second anchoring cleat 22. The spacer
guide 24.
[0031] A mounting hole 26 is formed through the planar sheet 12 of
the joiner clip 10. The mounting hole 26 is a through hole
configured to receive a fastener. The mounting hole 26 is
positioned between the first portion 14 and second portion 16 of
the planar sheet 12 and is in line with the spacer guide 24.
According to some embodiments, the joiner clip 10 includes a
plurality of mounting holes formed through the planar sheet 12,
which are also in line with the spacer guide 24. According to
various embodiments, the mounting hole 26 is pressed or drilled
into the planar sheet 12.
[0032] The dimensions of the joiner clip 10 can be varied based on
various use conditions and requirements. According to various
embodiments, the overall length L of the planar sheet is 1.5 to 3
inches long thereby providing a broad attachment base for the
panels that allows for a reduction in precision required in cutting
the panels and lining them up precisely with the substrate, thereby
requiring less labor and installation time. According to various
embodiments, the overall height H of the planar sheet is and 0.5 to
2 inches in height. Preferably the planar sheet is 2.25 inches long
and 1.125 inches high. In some embodiments, the first and second
anchoring cleats 20, 22 are 0.25 inches long, however it is to be
understood that the two anchoring cleats need not be the same
dimensions. According to various embodiments, the anchoring cleats
20, 22 protrude from the first face 18 at least 0.125 inches. In
some embodiments, the anchoring cleats 20, 22 are spaced at least
0.5 inches from the spacer guide 24, creating a wide point of
attachment and keeping the panel attachment away from the edges,
thereby reducing cracking of the panels 30. In some embodiments,
the mounting hole is colinearly spaced apart from the spacer guide
24 by at least 0.125 inches.
[0033] As shown in FIGS. 4-6, the joiner clip 10 is configured to
secure panels 30 to a substrate 40. According to some embodiments,
the panels 30 are fiber cement panels. In some embodiments, the
substrate 40 is stud. The joiner clip 10 is designed such that the
point of the first anchoring cleat 20 pierces a first panel 30 and
the point of the second anchoring cleat 22 pierces a second panel
30, thereby preventing the panels 30 from slipping out of position.
The spacer guide 24 is configured to be positioned between the
first and second panels 30. The spacer guide 24 provides the
required gapping between two panels 30 to allow for expansion of
the panel while also ensuring that the panels are equally spaced
for aesthetic purposes. The spacer guide 24 also creates a butt
joint 46 between two panels 30 with little effort from a user and
with litter error.
[0034] In installation, two panels 30 are posited relative to the
substrate 40. The joiner clip 10 is then positioned relative to the
panels 30 with the first anchoring cleat 20 piercing the first
panel 30 and the second anchoring cleat 22 piercing the second
panel 30. The spacer guide 24 is positioned between the two panels
to properly gap the panels 30. The joiner clip 10, vertical stud
substrate 40, and a first and second panel 30 define a construction
unit 60 according to embodiments of the present disclosure. In
embodiments where the sheet 12 is slightly curved as shown in FIG.
3B, the sheet 12 is forced into a planar configuration when the
cleats 20, 22 pierce the panels 30, creating an internal tension
within the sheet 12 to revert to its naturally curved position.
This internal tension acts on the panels through the cleats 20, 22
and draws the panels toward each other. A fastener 50 is then
inserted into the mounting hole 26 from the side of the second face
19 of the joiner clip 10. The fastener 50 penetrates the substrate
40 thereby securing both panels 30 to the substrate 40. The
fastener 50 may be pre-set in the mounting hole 26. In some
embodiments, number ten or number twelve (#10 or #12) pancake or
wafer head screws are used in conjunction with the joiner plate 10.
The (#10 or #12) pancake or wafer head screws provide a minimum
withdrawal resistance in 33 KSI 24 ga. galvanized steel of not less
than 250 lbf.
[0035] Given that the mounting hole 26 is colinear with the spacer
guide 24, the fastener generally passes through the gap between the
panels that is created by the spacer guide 24. The force of
tightening the fastener 50 into the underlying substrate 40 is
dispersed along the planar sheet 12, pulling the panels 30 into
secure position against the substrate 40. Because the head of the
fastener 50 is in contact with the second face 19 of the joiner
clip 10, the panels 30 that are secured to the substrate are
protected from damage by the fastener. As shown in FIG. 4, some
embodiments of a construction unit 60 include a siding strip 42 or
vertical rainscreen batten that is secured to the substrate 40
beneath the panels 30. According to various embodiments, additional
panels 30' are layered upon the panels 30 and cover the joiner clip
30 and fastener 50.
[0036] Any patents or publications mentioned in this specification
are herein incorporated by reference to the same extent as if each
individual publication was specifically and individually indicated
to be incorporated by reference.
[0037] The foregoing description is illustrative of particular
embodiments of the invention, but is not meant to be a limitation
upon the practice thereof.
