Cavity wails of a masonry veneer tied to a stud backup

an esthetically pleasing appearance while being less

cavity wall used in both residential and commercial
buildings is a brick veneer tied to a stud backup wall.
The brick veneer is tied to the stud backup wall by use
of masonry =or brick veneer anchors. There are two types ,
of such anchors in common use. Flush ,mount anchors which

through the wall anchors which pass through the exterior
wall covering and are mounted to the side of the stud in
the interior of the wall caVity. Flush mount brick
veneer anchors offer the advantage that it is not
necessary to cut or pierce the covering material for the

stud backup wall in order to install the anchors. This
can maintain the integrity of the properties of the
exterior.covering of the stud backup wall. as well as
being simpler to install.
One disadvantage of flush mount anchors is that such
anchors are generally L-shaped with the base of L
.providing.an anchor plate for attachment to the stud
backup wall and the leg of the L provide a tie wire
holding portion with a slot at its end through which a.
brick tie wire is inserted. The brick tie wire.is
.mortared between two rows of bricks to provide a secure
connection between the brick veneer and backup wall. The
disadvantage of this type of construction is that the
mOunting holes are placed in the anchor plate to the side
.of the brick tie portion. and thus any compression or
extension forces exerted through the brick tie wire to
. the brick veneer anchor are offset from the anchor points
which can cause the anchor plate to pivot aboiat the
anchor points and weaken the connection between the =
.anchor plate and the stud backup wall. This offset can =
also result in damage to the exterior covering as the
anchor plate rotates about the anchor points.

anchor which transfers the load from the tie wire holding

backup wall. =

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
= 'A first embodiment of a flush mount brick veneer anchor
of the present invention is illustrated in Figures 1
through 5 generally indicated by the numeral 10. The
= 25 flush mount brick veneer anchor 10 is designed to mount
on the exterior covering 12 which is attached to studs 14
= making up an exterior wall. The flush mount brick veneer
anchor 10 is attached to the exterior wall by screws 18
inserted through mounting holes 20 in the flush. mount
brick veneer anchor through the exterior covering '12 and
. into the stud 14 of the exterior wall. In this way the
.forces exerted on the brick veneer'anchor 10 are passed

through to the support provided by the studs 14 of the
exterior wall by means of the anchoring screws 18.

The flush mount brick veneer anchor of the present
= invention has an anchoring portion 22 which holds the
mounting holes 20 and a tie wire holding portion 24
extending perpendicularly from the anchoring portion 22
and having a slot 26 to hold the tie wire 28 for tying a
brick facing 30 to the exterior wall,
=
In the first embodiment illustrated in Figures 1 through
5 the anchoring portion 22 is a doubled up layer.of metal
with the tie wire holding portion 24 extending
perpendicularly from the outer layer of the doubled up
metal. This brick veneer anchor 10 is formed of a blank
of metal which is cut to the desired size and slit to
form the tie wire holding portion and the mounting holes
punched out along with the tie wire receiving slot 26
during the initial step of the manufacturing process:
The brick veneer anchor 10 is then folded along the fold
lines 32 and 34 as shown in Figure 1 to form the doubled
20 up anchoring portion 22 with the tie wire receiving
= . . portion 24 extending perpendicularly from the outer layer
of the doubled up anchoring portion 22. Fold line 34 is
in line with the mounting holes. 20. The two layers of
the anchoring portion 22 are then attached to one
= 25 another, either through spot welding or suitable metal
adhesives between the two layers.
Figures 2 through 5 illustrate the use of the first
embodiment of the flush mount brick veneer anchor 10 of
the present invention. The flush mount brick veneer
anchor 10 is attached to the exterior surface of the
covering by means of suitable fastening means 18 which
are driven through the mounting hole 20 and the exterior
covering material 12 into the stud 14 of the exterior

wall. A brick tie wire 28 is fed through the tie wire
holding opening 26 of the tie wire holding portion 24 and
is mortared between bricks of the brick veneer wall to
tie the brick veneer wall to the backup wall and to
provide an intermediate air space or cavity for air
circulation.
A second embodiment of .a flush mount.brick veneer anchor
of the present invention is illustrated.in Figure 6
generally indicated by the numeral 50. This embodiment
of the flush mount brick veneer anchor 50 has a single
layer anchoring portion 52 which holds the mounting holes
54 and the tie wire holding. portion 56 extending
perpendicularly from the anchoring portion 52 to hold the.
tie wire 28 for tying a brick facing to the exterior
wall. Similar to the first embodiment, this embodiment
=
of the flush 'mount brick veneer anchor 50 is formed from'
a single piece of metal by cutting slits from an edge of
the anchoring portion to a bend line in line with the
= 20 mounting holes, 54 and the tie wire holding portion 56 is
bent along the bend line perpendicularly away from the
anchoring portion. As illustrated in Figure 6, it is. =
preferred if the anchoring portion is an "E" shape with .a.
central tab 60 centrally located between the edges of the .
= 25 tie wire holding portion 56. Central tab 60 provides for
an increase support surface for the anchoring portion 52
against the covering material of the exterior wall. .
A third embodiment of a flush mount brick veneer anchor
= 30 of the present invention is illustrated in Figure 7
generally indicated by the numeral 80. Similar to the
other embodiments, brick:veneer anchor 80 has an
anOhoring portion 82 which holds the mounting holes 84
and a tie wire holding portion 86 extending
=

perpendicularly from the anchoring portion 82 holding tie
wire 28 for tying a brick facing to the exterior wall.
Similar to the second. embodiment, this embodiment of the
brick veneer anchor 80 has an "E" shape with a central
tab 90 to increase the support area of the anchoring .
portion 82 against the surface of the exterior covering ,
of the backup wall. In this embodiment however the
central tab is formed by a D cut in the central portion
of the anchoring portion 82 to the opposite side of the
cuts utilized to form the tie .wire holding portion 86. .
During the bending operation to form the flush motnt
brick'veneer anchor 80 as the tie wire holding portion 86
is bent to extend perpendicularly from the anchoring
portion 82, the central tab 90 is bent to be displaced
.180 from its original position on the anchoring portion
to project:to the opposite side of the tie wire holding
= = portion 86. This design of the flush meunt brick veneer
anchor of the present invention offers an additional
advantage in that it requires less metal to be utilized
= 20 in the construction of the flush mount brick veneer
anchor while maintaining the desired support and other
advantages of the present invention. This results in the
decreased cost of production of the flush mount brick
veneer anchor.
= 25 =
The flush Mount brick veneer anchor of the present-
invention provides for mounting holes to attach the brick
veneer anchor to a backup wall being aligned with the tie
wire holding portion. In this way, any forces exerted .
30 through the brick tie wire to the brick veneer .anchor
and, in particular,' the typical compression and extension
forces, are transferred directly through the mounting
points to the backup' wall. This overcomes prior art
disadvantages of the anchor plate pivoting about the
7

mounting points under extreme loads and weakening the
connection between the anchor plate and the backup wall
thus minimizing potential damage to the exterior covering
of the backup wall as the anchor plate rotates about the
anchor points.
Although various preferred embodiments of the present
invention have= been described herein in detail, it would
be appreciated by those skilled in the art that
variations may be made thereto without departing from the =
