Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to the field of
building construction elements and, more particularly, to a wall
tie with rounded corners.
BACKGROUND OF THE INVENTION
[0002] One typical construction arrangement commonly in use today
calls for a brick veneer to be assembled over a wood frame backing.
To maintain good insulation properties, the layer of brick is laid
with an air gap between the bricks and the backing. However, in
order to maintain the stability of the assembly, a number of brick
ties or wall ties are attached to the backing, such as for example
by nailing, and then the layer of bricks is laid with the ties
joined to the brick layer by mortar.
[0003] As described by Masonry Advisory Council, Park Ridge, Ill.,
the Building Officials and Code Administrators (BOCA) National
Building Code BOCA 1405.5.3 states that wall ties must be installed
at not less than one per three square feet of wall area, not more
than 32 inches apart horizontally, and not more than 16 inches
apart vertically. Typically, wood stud framing is on 16'' centers,
so the limit of 32'' on center horizontally would permit one tie in
every other stud, but the one tie per three square feet requirement
would then limit the vertical spacing to 13''+, which would require
that ties be installed in every fourth course of brick, which may
unneccesarily slow down the mason when laying the brick. Therefore,
in order to comply with BOCA and maximize mason productivity, it is
suggested that a wall tie be attached to each stud (at 16'' or 24''
o.c.) not to exceed every 16'' vertically (6 courses for 21/4''
high units [modular and standard] and 5 courses for 23/4'' high
units [queen, princess, king, engineer, and norwegian]).
[0004] Random installation of wall ties without regard to bed joint
height serves no purpose. Wall ties are optimally effective when
nailed at the level of the bed joint. If wall ties are installed by
framing carpenters or by someone other than the brickmason, an
acceptable practice is to nail them on level horizontal lines
corresponding to bed joint heights at regular vertical intervals.
Compliance with BOCA 1405.5.3 as described above would be achieved
by a tie on every stud at 16'' vertically. This would permit the
ties to be anchored in the same course of brickwork. Ties nailed
randomly serve little or no purpose.
[0005] If brickmasons install wall ties, they should follow the
same spacing requirements stated above. Tie requirements do not
change according to variable properties of brick, such as
absorption. Tie installation by competent masons can result in more
effective tie strength if the nail is even with the top of the
course of brick receiving the tie. If the nail is above or below
the top of the course of brickwork receiving the tie, the
effectiveness of the tie will be measurably reduced.
[0006] Wall ties on wood stud framing serve one purpose: They
transfer lateral forces on the brickwork, primarily wind loads,
back to the wood framing. The action of the wind can produce a
lateral force in either the form of pressure or suction on the
brickwork, and the ties deliver that load to the framing system
which resists the load.
[0007] The typical wall tie is formed of a length of metal,
commonly galvanized steel, and cut to length in the manufacturing
process. In doing so, sharp corners are formed at each end of the
tie, which can be hazardous to the installer, whether the tie is
installed by the frame carpenter or the brickmason. These sharp
corners have been known to cut through the skin of the installers,
and to pose a hazard to those who come in contact with the ties
sticking from the backing wall until they are covered up by the
laying of brick over the wall.
[0008] The present invention is directed to solving this long felt
need in the art.
SUMMARY OF THE INVENTION
[0009] The present invention provides a corrugated wall tie, formed
in the usual fashion, with the additional step in the manufacturing
process of rounding the corners of tie. As used herein, the term
"rounding" as it refers to the corners means that the curvature of
the corners meets the long and short sides of the tie tangentially.
In this way, no point is left on the tie to cause injury to the
installer and other workers at the job site. This also makes the
manufacturing simple and easy, adding very little to the cost of
the tie, which is typically used in large quantities on projects
involving the application of the brick veneer.
[0010] These and other features and advantages of this invention
will be apparent to those skilled in the art from a review of the
following detailed description along with the accompanying drawing
figures.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 is a perspective view of a wall construction wherein
the present invention may find application.
[0012] FIG. 2 is a plan view of a wall tie of this invention
showing the rounded corners.
[0013] FIG. 3 is a perspective view of a wall tie of this
invention.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0014] FIG. 1 illustrates a typical wall construction 10 that makes
use of a wall tie. The wall construction 10 comprises mainly a wood
frame wall backing 12 and a brick veneer 14, joined together with a
plurality of wall ties 16. The wall ties may be nailed to the
backing 12 by a framing carpenter at predetermined heights, or by
the brickmason as he goes along. The wall tie is typically about
63/8'' long and 7/8'' wide. The tie is preferably 22 gage, or
0.029'' minimum thickness. Construction codes dictate a minimum of
one inch for an air gap 18 between the backing and the brick
veneer.
[0015] FIGS. 2 and 3 show a preferred embodiment of the wall tie 16
of this invention. The wall tie comprises a corrugated body 17 and
includes a rounded corner 20 at the junction of each long side and
short side. Note that the rounded corners are tangent to the
respective long and short sides, with no sharp corner or points, as
in the art. The tie 16 also includes a plurality of nail holes 22,
spaced apart along the length of the tie, adapted to receive a
properly sized nail to affix the tie to a wood frame backing.
[0016] FIG. 3 illustrates that the tie is preferable corrugated
with uniformly spaced lands 24 and grooves 26. This shape of the
tie is common in the art, but for the rounded corners.
[0017] Modifications and variations may be made to the embodiments
described herein and depicted in the accompanying drawings without
departing from the spirit of the present invention. Accordingly, it
is understood that the embodiments described herein are
illustrative only and are not intended to limit the scope of the
present invention.
