Description
TITLE OF THE INVENTION: STEEL STUD CLIP
OUND OF THE INVENTION
The t invention belongs to a class of stud mounting clips that are useful in the
construction of buildings, particularly light commercial buildings.
Many buildings are constructed with steel stud wall systems in order to e reduced
environmental concerns, fire safety and d susceptibility to warpage, infestation, rust and
rot. For a variety of reasons, it is often advantageous to construct these walls systems with
connectors that permit a degree of ve movement between the framing members. Buildings
often settle on their foundations once constructed, which can cause exterior walls to go out of
plumb, in turn causing damage to the surrounding foundation and to interior structures such as
floors. Exterior walls and , ularly of light commercial buildings, are often made
from materials that have different coefficients of expansion than that of the structure’s exterior
sheathing. With exposure to extremes of temperature, gaps can be produced in the exterior
sheathing panels if they expand a contract more than the framing, allowing cold air and moisture
to intrude. Exterior walls of buildings are also subject to deflection from wind or seismic forces,
and a degree of m of movement can reduce stress and t fracture of connected parts.
And curtain walls (e.g., partition walls) are not designed to support vertical loads and must
therefore by isolated from deflection of the primary load-bearing support structure of the
building due to changes in live or dead loads carried by that structure.
A variety of slide, or slip, clips that permit relative movement between ural
members have been made, but none have successfully optimized the use of material in the clips
and the loads achieved by the clips.
Accordingly, there is a need to e a slip clip connector designed to achieve the
maximum possible loads from the minimum amount of material, thereby realizing substantial
savings, in cost as well as material, over the prior art. There is a further need to provide clips
that include the same improvements to ze load and minimize material use, but do not
permit slip between members.
OBJECT OF THE INVENTION
[0004a] It is an object of the present invention to at least substantially satisfy the above needs or
to at least provide a useful alternative.
BRIEF SUMMARY OF THE INVENTION
[0004b] The present invention provides a first building structural connection sing:
a. a first building structural member;
b. a second ng structural member;
c. a first sheet metal tor, said first connector comprising:
i. a first plate fastened to said first building structural member; and
ii. a second plate fastened to said second building structural member,
wherein:
(a) said first plate has first and second fastener openings of a first
ity of fastener openings that includes one or more additional fastener openings in addition
to said first and second fastener openings, a first inner edge, a first outer edge, a first side edge
and a second side edge, said first fastener opening being the closest of said first plurality of
er openings to said first side edge, said second fastener opening being the closest of said
first plurality of fastener openings to said second side edge, said first and second er
openings being closer to said first outer edge than said one or more additional fastener openings,
said one or more onal er openings being closer to said first inner edge than said first
and second fastener openings;
(b) said second plate has a second plurality of fastener openings, a
first inner edge, a first side edge and a second side edge, said first side edge of said second plate
intersecting said first inner edge at a first corner juncture, said second side edge of said second
plate intersecting said first inner edge at a second corner juncture;
AH26(9430493_1):DJM
(c) said first inner edge of said first plate is joined to said second
inner edge of said second plate to form an inner angular juncture;
(d) a first reinforcing flange is attached to said first side edge of said
first plate and to said first side edge of said second plate;
(e) a second reinforcing flange is attached to said second side edge of
said first plate and to said second side edge of said second plate;
(f) a first embossment in said second plate, d between said
second plurality of fastener gs and said first inner edge of said second plate, reinforces
said second plate and is adjacent said first corner juncture; and
(g) a second embossment in said second plate, d between said
second plurality of fastener openings and said first inner edge of said second plate, reinforces
said second plate and is adjacent said second corner juncture.
In an embodiment, angled connectors with rolled edge flanges having unique fastener
geometry in one plate and reinforcing embossments in the other optimally bute loads
among fasteners and y achieve higher tension loads while using the smallest possible
number of fasteners and the lightest possible material for the connector.
In another embodiment, angled connectors with rolled edge flanges and slotted fastener
openings that also have rolled edges, reinforce the slotted fastener openings, stiffening the
connector plate, and reducing unnecessary friction between the connector plate and the
structural member to which it is attached.
The tors can be made from lighter-gauge materials than the prior art connectors of
the same type, but the connectors of the t disclosure equal or exceed the same prior art
tors in mance. The preferred al for the connectors is 16-gauge Grade 40 hotdip
galvanized G90 sheet steel. The ability to go down one or even two gauges results in
substantial savings not only in the cost of sheet steel, but also in storage and transportation costs,
both of which are reduced when the connectors are lighter and thinner than the prior art. The
improvements of the present disclosure were only possible due to careful consideration and
calculation using finite element analysis to ensure that loads are transferred inward from the
roll-stiffened edges and distributed among the fasteners to maximize the strength of the
connection.

DETAILED DESCRIPTION OF THE INVENTION
The present invention in its preferred form is a building structural connection 1 between
a first building structural member 2 and a second building structural member 3. Preferably, the
first building structural member 2 is a supporting member 2 and the second ng structural
member 3 is a supported structural member 3. As shown in Figs. lA and 8A, the first building
structural member 2 is a horizontal beam with an attached ledger 2 and the second building
structural member 3 is a vertically-oriented channel-shaped wall post 3. As shown in Fig. 5A,
the first building structural member 2 is a horizontal beam with an attached vertically-oriented
channel-
AH26(9430493_1):DJM
shaped header 2 — the second building structural member 3 is a vertically—oriented channel—
shaped wall post 3. As shown in Fig. 11A, the first building structural member 2 is a horizontal
beam 2 and the second building structural member 3 is a vertically—oriented l—shaped wall
post 3.
The connection 1 n the first building structural member 2 and the second building
structural member 3 is made with a first connector 4. The first connector 4 is preferably L-
shaped, with a first plate 5 ed to the first building structural member 2 and a second plate 6
fastened to the second building structural member 3. Preferably, said first plate 5 and said
second plate 6 are generally planar and joined at right angles to each other. In the most common
embodiments, the connector 4 allows for relative vertical movement between the first and second
building structural members 2 and 3. A simple 90—degree change in orientation would allow the
connector 4 to permit relative horizontal movement. The connector 4 is preferably made from
l6—gauge cold formed sheet steel, bent, cut, ed and punched on automated manufacturing
machinery. Preferably, the connector 4 is used to connect cold formed steel structural s.
As shown in Fig. 1B, the first plate 5 has first and second fastener openings 7 and 8 of a
first ity of fastener openings 9 that includes one or more additional fastener openings 10 in
addition to said first and second fastener openings 7 and 8.
The first plate 5 has a first inner edge 11, a first outer edge 12, a first side edge 13 and a
second side edge 14.
As shown in Fig. 3C, the first fastener opening 7 is the t of the first plurality of
fastener openings 9 to the first side edge 13. The second fastener opening 8 is the closest of the
first plurality of fastener openings 9 to the second side edge 14. The first and second er
openings 7 and 8 are closer to the first outer edge 12 than the one or more additional fastener
openings 10. The one or more additional fastener gs 10 are closer to the first inner edge
11 than the first and second fastener openings 7 and 8.
As shown in Fig. 3A, the second plate 6 has a second plurality of er openings 15, a
first inner edge 16, a first side edge 17 and a second side edge 18. The first side edge 17 of the
second plate 6 intersects the first inner edge 16 at a first corner juncture 24. The second side
edge 17 of the second plate 6 intersects the first inner edge 16 at a second corner juncture 25.
The first inner edge 11 of the first plate 5 is joined to the first inner edge 16 of the second
plate 6 to form an inner angular juncture 19. Preferably the inner angular juncture 19 is 90
degrees.
As shown in Fig. 1B, a first reinforcing flange 20 is attached to the first side edge 13 of
the first plate 5 and to the first side edge 16 of the second plate 6. A second reinforcing flange
21 is attached to the second side edge 14 of the first plate 5 and to the second side edge 18 of the
second plate 6. The first and second reinforcing flanges 20 and 21 are continuous, with no
breaks at the juncture 19 between the first plate 5 and the second plate 6.
As shown in Fig. 3A, the tor 4 includes a first ment 22 in the second plate
6. The first embossment 22 is located between the second ity of fastener openings 15 and
the first inner edge 16 of the second plate 6. The first embossment 22 reinforces the second plate
6 and is adjacent said first corner juncture 24.
The connector 4 also includes a second embossment 23 in the second plate 6. The second
embossment 23 is located between the second plurality of fastener openings 15 and the first inner
edge 16 of the second plate 6. The second embossment 23 reinforces the second plate 6 and is
adjacent the second comer juncture 25.
The unique, staggered distribution of the first plurality of fastener openings 9 distributes
load evenly among the fasteners 9, while the first and second embossments 22 and 23 distribute
loads in the second plate 6, allowing the connector 4 of the present ion to be made from 16
gauge sheet metal while analogous connectors have to be made from 14 or even 12 gauge sheet
metal, which is substantially more expensive to manufacture and transport, adding cost and
waste at every stage. This distribution of fastener openings 9 is not found in any other slide, or
slip, clip.
As shown in Figs. 1A-3A, 3C-4A, 4C, 8A—9A, and , preferably the first connector
4 has one or more gusset darts 26 in the inner angular juncture 19 that reinforce the inner angular
juncture 19.
[005 l] Preferably, a first plurality of fasteners 27 attaches the first plate 5 to the first building
structural member 2. A second plurality of fasteners 28 preferably es the second plate 6 to
the second building ural member 3.
Preferably, the ers 28 of the second plurality of fasteners 28 are screws 28. The
preferred fasteners 27 for attaching the connector 4 to first structural members 2 made from steel
are #12 or #14 hex-head fasteners 27, automated power-actuated gun-driven fasteners 27 or,
alternatively, welds 27. The preferred fasteners 27 for attaching the connector 4 to first
structural members 2 made from te are concrete screws 27. The preferred fasteners 28 for
attaching the connector 4 through slots 15 are shouldered, or d—shank, screws 28.
As shown in Figs. lA—lB, 3A, 4A, 5A—5B, 7A, llA—l 1B and 12A, the second ity of
fastener openings 15 is preferably formed as a plurality of elongated slots 15 in the second plate
6 when movement between the structural member 2 or 3 and the connector 4 is desired.
Preferably, the first building ural member 2 is fastened to the first connector 4 so
that the first building structural member 2 cannot move relative the first plate 5 of the first
connector 4.
The second building structural member 3 is preferably fastened to the first connector 4 so
that the second building structural member 3 can move relative to the second plate 6 of the first
connector 4.
Preferably, the fasteners of the second plurality of ers 28 are shouldered, or
stepped—shank screws 28. ered screws 28 have a head 29, an unthreaded shank portion 30
immediately below the head 29, a threaded shank portion 31 below the unthreaded shank portion
, and a tip 32. The unthreaded shank portion 30 allows the second building structural member
3 and the fasteners 28 attached to it to move ve to the second plate 6 without interference
between the second plurality of fastener 28 and the second plate 6 of the first connector 4.
As shown in Figs. lA—7C and 11A—12D, the elongated slots 15 preferably have rolled
edges 33 that stiffen the elongated slots 15 and reinforce the second plate 6. The rolled edges 33
also reduce friction between the second plate 6 and the second building structural member 3 by
reducing the surface contact between the second plate 6 and the second building structural
member 3.
[005 8] As shown in Figs. lA—3C, in a preferred embodiment, the connector 4 of the present
ion has four fastener openings 9 in the first plate 5, which is fixedly ed to the first
building structural member 2. The two outer corners 34 of the first plate 5 are red to save
material and make the connector 4 easier and safer to handle. A first fastener opening 7 is near
the first outer corner 34 and a second fastener opening 8 is near the second outer corner 34. The
two additional fastener openings 10 are between the first fastener opening 7 and the second
fastener opening 8 and are closer to the inner angular juncture 19 n the first plate 5 and
the second plate 6. The connector 4 also has first and second embossments 22 and 23 in the
second plate 6. The embossments are oidal. The first embossment 22 is near the first
comer juncture 24 of the second plate 6 and the second embossment 23 is near the second corner
juncture 25 of the second plate 6. The second plate 6 has two elongated slot openings 15 that
extend across the second plate 6 generally parallel to the inner angular juncture 19 between the
first plate 5 and the second plate 6. The slots 15 have rolled edges 33 that reinforce the slots 15
and stiffen the second plate 6. The rolled edges 33 are rolled down to project ly from the
attachment side 40 of the second plate 6, which has an open side 41 facing in the opposite
direction. The attachment side 40 of the second plate 6 faces the second building ural
member 3. Similarly, the first plate 5 has an ment side 38 and an open side 39 facing in the
opposite direction. The attachment side 38 of the first plate 5 faces the first building structural
member 2. There is a single round pilot hole 35 halfway between the slots 15 and midway
between the first and second side edges 17 and 18 of the second plate 6. As with the first plate 5,
the outer corners 36 of the second plate 6 are chamfered. A first outer edge 37 of the second
plate 6 runs from corner 36 to corner 36. The first end 42 of the first rcing flange 20, and
the first end 43 of the second reinforcing flange 21 both projecting from the first plate 5, are
angled to match the chamfered outer s 34 of the first plate 5. Similarly, the second end 44
of the first reinforcing flange 20, and the second end 45 of the second reinforcing flange 21, both
projecting from the second plate 6, are angled to match the chamfered outer corners 36 of the
second plate 6.
As shown in Figs. 4A-4C, in another preferred embodiment the connector 4 is basically
the same as shown in Figs. 1A-3C, except that the second plate 6 is much longer from first inner
edge 16 to first outer edge 37. The second plate 6 therefore has a third elongated slot opening 15
and a pair of elongated embossments 46 that run parallel to, and between, the first and second
side edges 17 and 18, from the first and second trapezoidal embossments 22 and 23 almost to
the nearest of the elongated slots openings 15. The elongated ments 46 help to stiffen the
longer second plate 6.
As shown in Figs. 5A—7C, in a third preferred embodiment the orientation of the
connector 4 is different and the second plate 6 projects down instead of to the side. In this case,
the connector 4 is er, in order to fit within a first building structural member 2 that is a
channel-shaped header 2. In this embodiment, there is only one additional fastener g 10
between the first and second fastener openings 7 and 8 of the first plurality of fastener openings
9 in the first plate 5. This embodiment also demonstrates the reinforcing capacity of the rolled
edges 33 of the elongated slot openings 15 in the second plate 6, since there are no first and
second embossments 22 and 23 in the second plate 6. Because the elongated slot gs 15
are oriented longitudinally, el to the first and second side edges 17 and 18 of the second
plate, the rolled edges 33 stiffen most of the second plate 6 between the first and second
reinforcing flanges 20 and 21.
As shown in Figs. 8A—10B, in fourth and fifth preferred embodiments the connector 4 is
made with a second plurality of fastener openings 15 in the second plate 6 that are conventional
round and triangular fastener openings 15, rather than elongated slot openings 15.
Conventionally, round openings 15 denote those that must be filled to e normal load
values; triangular openings 15 denote those that can be filled to achieve a maximum load value
in excess of the normal load values. These embodiments are intended for applications where a
slip, or slide, connection is not required.
As shown in Figs. llA—l2D, in a sixth preferred embodiment the connector 4 is
substantially wider and attaches to the top or bottom of the first building structural member 2
rather than to a side. This ment is used in ular where a wall post or stud 3 bypasses
the supporting beam 2. In this embodiment there is a third reinforcing flange 47 attached to the
first outer edge 37 of the second plate 6, running from the first outer chamfered corner 36 to the
second outer chamfered comer 36. Instead of a staggered first plurality of fastener openings 9,
the first plurality of fastener gs 9 is a line of fastener openings 9 running from the first
side edge 13 of the first plate 5 to the second side edge 14 of the first plate 5. The second plate 6
is stiffened by two pairs of elongated embossments 46 that are centrally d. There are three
parallel elongated slot openings 15 with rolled edges 33 at each end of the second plate 6, near
the first side edge 16 and the second side edge 17 of the second plate 6, respectively.
As shown in Figs. lA—4C and 8A—10C, the first embossment 22 in the second plate 6 is
preferably siX material thicknesses from the first side edge 17 of the second second plate 6; the
second embossment 23 in the second plate 6 is preferably six material esses from the
second side edge 18 of the second plate 6.
Preferably, the first embossment 22 in the second plate 6 is generally trapezoidal, with a
first diagonal edge 48 that generally leads toward the gusset dart 26 closest to the first side edge
17 of the second plate 6; preferably, the second embossment 23 in the second plate 6 is generally
trapezoidal, with a first diagonal edge 48 that generally leads toward the gusset dart 26 closest to
the second side edge 18 of the second plate 6. The diagonal edges 42 and 43 funnel load toward
the gusset darts 26 and the inner onal fastener openings 10 in the first plate 5. Load is
ed inward and away from the first and second reinforcing flanges 20 and 21 in order to
distribute load to the inner additional fastener openings 10 of the first plurality of fastener
openings 9. In general, load is inantly ed where the connector 4 is stiffest, and the
first and second embossments 22 and 23, in combination with the gusset darts 26, stiffen the
connector 4 so that load is more evenly distributed among the first plurality of fastener openings
in the first plate 5.
The first and second embossments 22 and 23 in the first plate 6 are preferably embossed
to a depth of one material thickness, most preferably 0.057 inches. A greater embossment depth
than two material thicknesses would exceed the sheet metal’s ability to stretch without
fracturing.
Most preferably, the first and second embossments 22 and 23 in the first plate 6 mirror
each other. Each has a first vertical edge 49 parallel to the first and second side edges 17 and 18
of the second plate 6. In the preferred embodiments shown in Figs. 1A—4C, in which the first and
second plates 5 and 6 are four inches wide, the first vertical edge 49 of the first embossment 22
faces, and is 0.25 inches away from, the first side edge 17 of the second plate. The first vertical
edge 49 of the second embossment 23 faces, and is 0.25 inches away from, the second side edge
18 of the second plate. The first and second embossments 22 and 23 extend an additional 0.938
inches away from the first and second side edges 17 and 18, respectively. Each of the first and
second embossments 22 and 23 has a first horizontal edge 50 that is orthogonal to the first
vertical edge 49 and parallel to the first inner edge 16 of the first plate 6. The first ntal
edges 44 of the first and second embossments 22 and 23 face, and are 0.375 inches away from,
the first inner edge 16 of the first plate 6. Each of the first and second embossments 22 and 23
has a second horizontal edge 51 further away from the first inner edge 16 of the first plate 6,
parallel to the first horizontal edge 50, and 0.5 inches away from the first ntal edge 50.
The second horizontal edges 45 are shorter than the first horizontal edges 44. First diagonal
edges 42 join the first ntal edges 44 to the second horizontal edges 45; the angle between
the first diagonal edges 42 and the first horizontal edges is 35 degrees. The edges 42-45 of the
first and second embossments 22 and 23 meet at rounded comers 52 with inch radii.
Preferably, the fastener openings 9 of the first plurality of fastener openings 9 in the first
plate 5 are round and match the size of the first plurality of fasteners 27. Exact positioning of the
first plurality of fasteners 27 is ary in order to correctly calculate the loads distributed
among the first plurality of fasteners 27. Furthermore, if the fastener openings 9 of the first
plurality of fastener openings 9 were oversized or slotted, the material of the first plate 5 would
be more likely to tear around the fasteners 27 of the first plurality of fasteners 27, reducing
m achievable loads. Furthermore, the removing additional material from the first plate 5
would reduce the first plate 5 and weaken the connection 1.
As shown in Figs. 1A—10C, in the preferred embodiments in which the first plate is four
inches wide, the first fastener opening 7 of the first plurality of fastener gs 9 is preferably
0.5 inches on center from the first side edge 13 of the first plate 5. The second fastener opening
8 of the first plurality of fastener openings 9 is preferably 0.5 inches on center from the second
side edge 14 of the first plate 5. If there is only one onal fastener opening 10 in the first
plate 5, as shown in Figs. 5A—7C, it is preferably spaced 1.625 inches on center from both the
first side edge 13 and the second side edge 14. If there are multiple additional fastener openings
, one is 1.25 inches on center from the first side edge 13 and one is 1.25 inches on center from
the second side edge 14. If there are two additional fastener openings 10, as shown in Figs. 1A—

openings 7 and 8 preferably are 0.625 inches on center from the first outer edge 12 of the first
plate 6. The additional fastener openings 10 preferably are 0.75 inches from the first outer edge
12 of the first plate 6. The round fastener openings 9 of the first plurality of fastener openings
are preferably 0.216 inches in er. The round fastener openings 15 of the second plurality
of fastener openings are ably 0.190 inches in diameter.
As shown in Figs. 1A—4C and 8A—10C, the gusset darts 26 are preferably embossed to a
maximum height of 0.125 , each with two sides 53 defining an inner angle of 80 degrees,
as shown in . ably, there are two gusset darts 26, one spaced 1 inch on center from
the first corner juncture 24 in the second plate 6, and one spaced 1 inch on center from the
second comer juncture 25 in the second plate 6.
