Abstract
A veneer anchoring system discloses a low-profile wall tie for use in a wall having an inner wythe and an outer facing wythe. The wythes are in a spaced apart relationship and form a cavity therebetween. A combination of a wall anchor and a low-profile wall tie member is provided. The veneer anchoring systems hereof incorporate low-profile wall ties adapted for use with a dry-wall inner wythe and for use with a masonry block inner wythe. The masonry anchor has a truss portion with eye wire extensions welded thereto. The eye wires extend into the cavity between the wythes. Each eye wires accommodates the threading thereonto of a wire wall tie through the open end of the wall tie. The wall tie is then positioned so that the open end is utilizable as part of the facing wall tie. The masonry anchor is embedded in a bed joint of the interior wythe. The facing wythe is anchored by mounting in bed joints of the exterior wythe the open end of the low-profile wire formative wall tie. The low-profile permits the mortar of the bed joint to flow over and about the insertion end of the wall tie and secure the tie to the outer wythe. Where the inner wythe is a dry wall construct, a dry wall anchor, which is a stamped metal unit, is attached by sheetmetal screws to the metal vertical channel members of the wall.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an improved wall tie for a veneer anchoring system for use in conjunction with a wall structure having an inner wythe and an outer wythe, and, more particularly, to construction techniques for embedding low profile wire formatives in the bed joints of the inner and outer wythes having an interlocking arrangement between the wall tie and an inner wythe anchor. One aspect of the invention is to provide the anchoring of an outer wythe of brick or masonry veneer to an inner wythe of masonry block or drywall construction.
2. Description of the Prior Act
In the past, the use of wire formatives have been limited by the mortar layer thicknesses which, in turn are dictated either by the new building specifications or by pre-existing conditions, e.g. matching during renovations or additions the existing mortar layer thickness. While arguments have been made for increasing the number of the fine-wire anchors per unit area of the facing layer, architects and architectural engineers have favored wire formative anchors of sturdier wire. On the other hand, contractors find that heavy-wire anchors, with greater diameters, frequently result in misalignment and look towards substituting thinner gage wire formatives. Such substitution thereby facilitating alignment of courses.
In the past, there have been investigations relating to the effects of various forces, particularly lateral forces, upon brick veneer construction having wire formative anchors embedded in the mortar joint of anchored veneer walls. The seismic aspect of these investigations were referenced in the first-named inventor's prior patent, namely U.S. Pat. Nos. 4,875,319 and 5,408,798. Besides earthquake protection, the failure of several high-rise buildings to withstand wind and other lateral forces has resulted in the incorporation of a requirement for continuous wire reinforcement in the Uniform Building Code provisions. The first-named inventor's related Seismiclip
R
and DW-10-X
R
products (manufactured by Hohmann & Barnard, Inc., Hauppauge, N.Y. 11788) have become widely accepted in the industry. The use of a wire formative anchors in masonry veneer walls has also demonstrated protectiveness against problems arising from thermal expansion and contraction and has improved the uniformity of the distribution of lateral forces in a structure. However, these investigations do not address the mortar layer thickness vs. the wire diameter of the wire formative or technical problems arising therefrom.

None of the above provide the masonry construction system for an inner masonry wythe and an outer facing wythe with low-profile wire formative wall ties as described hereinbelow.
SUMMARY
In general terms, the invention disclosed hereby includes a veneer anchoring system incorporating a low-profile wall tie for use in the construction of a wall having an inner wythe and an outer facing wythe. The wythes are in a spaced apart relationship and form a cavity therebetween. In the first two embodiements disclosed, a unique combination of a wall anchor and a low-profile wall tie member is provided. The invention contemplates that the primary components of the system are reinforcing wire and wire formatives, such as truss reinforcement or ladder mesh reinforcements, providing wire-to-wire connections therebetween.
In third embodiment, the invention disclosed hereby includes a veneer anchoring system incorporating a low-profile wall tie for use in the construction of a wall having an inner dry-wall wythe and an outer facing wythe. The wythes are in a spaced apart relationship and form a cavity therebetween. In this embodiment, a unique combination of a wall anchor and, a low-profile wall tie member is provided. The invention contemplates that the primary components of the system are veneer anchors, as described in U.S. Pat. Nos. 4,021,990 and 4,598,518 and wire formative wall ties providing a positive interlocking connection therebetween.
In the mode of practicing the invention, wherein the inner wythe is constructed from a masonry block material, the masonry anchor has, for example, a truss portion with eye wire extensions welded thereto. The eye wires extend into the cavity between the wythes. Each eye wires accommodates the threading thereonto of a wire wall tie through the open end of the wall tie. The wall tie is then positioned so that the open end is utilizable as part of the facing wall tie. The masonry anchor is embedded in a bed joint of the interior wythe. The facing wythe is anchored by mounting in bed joints of the exterior wythe the open end of the low-profile wire formative wall tie. The low-profile permits the mortar of the bed joint to flow over and about the insertion end of the wall tie and secure the tie to the outer wythe. Because the eye wires have sealed eyelets and the open ends of the wall ties are sealed in the joints of the exterior wythes, a positive interengagement results.
In the mode of practicing the invention, wherein the inner wythe is a dry wall construct, a dry wall anchor, which is a stamped metal unit, is attached by sheetmetal screws to the metal vertical channel members of the wall. Each wall anchor accommodates in an opening therethrough the threading of a low-profile wire formative wall tie. As in the case of the masonry inner wythe, the open end of the wall tie is then positioned so that the open end is utilizable as part of the insertion end of the facing wall tie. The facing wall tie has a compressibly reduced in height and is mounted along the exterior wythe to receive the open end of wire wall tie with each leg thereof being placed adjacent one side of reinforcement wire. The low-profile of the facing wall tie is embedded in a bed joint of the exterior wythe. Because the dry wall anchor opening is a closed loop and the open ends of the wall ties are sealed in the joints of the exterior wythes, a positive interengagement results.
OBJECTS AND FEATURES OF THE INVENTION
It is an object of the present invention to provide in a wall structure having a facing wythe and a inner wythe, a veneer anchor system which employs a low-profile wire formative in the mortar joint of the facing wythe and is positively interconnected with a wall anchor attached to the inner wythe.
It is another object of the present invention to provide labor-saving devices to aid in the installation of brick and stone veneer and the securement thereof to an inner wythe.
It is yet another object of the present invention to provide a low-profile anchor system which ties to the continuous wire reinforcement of the inner wythe in a manner such that the mortar layer thickness in the facing wythe is readily maintainable.
It is a further object of the present invention to provide a low-profile anchor system comprising a limited number of component parts that are economical of manufacture resulting in a relatively low unit cost.
It is yet another object of the present invention to provide a veneer anchor system which is easy to install and is highly resistant to being pulled out of the mortar layer.
It is a feature of the present invention that the portion of the wall tie embedded in the joint of the facing wythe has a pattern impressed thereon.
It is another feature of the present invention that the wall tie is dimensioned with a sufficiently low profile so that, when inserted into the mortar layer, the mortar thereof can flow around and into the low-profile wall tie.
Other objects and features of the invention will become apparent upon review of the drawings and the detailed description.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to
FIGS. 1
to
3
, the first embodiment of a low-profile wall tie device of this invention is shown and is referred to generally by the numeral
10
. In this embodiment, a wall structure
12
is shown having an interior wythe
14
of masonry blocks
16
and an exterior wythe
18
of facing brick
20
. Between the interior wythe
14
and the exterior wythe
18
, a cavity
22
is formed. In the first embodiment, successive bed joints
24
and
26
are formed between courses of blocks
16
and the joints are substantially planar and horizontally disposed. Also, successive bed joints
28
and
30
are formed between courses of bricks
20
and the joints are substantially planar and horizontally disposed. For each structure, the bed joints
24
,
26
,
28
and
30
are specified as to the height or thickness of the mortar layer and such thickness specification is rigorously adhered to so as to provide the uniformity inherent in quality construction. Selected bed joint
24
and bed joint
28
are constructed to align, that is to be substantially coplanar, the one with the other. For purposes of discussion, the exterior surface
32
of the interior wythe
14
contains a horizontal line or x-axis
34
and an intersecting vertical line or y-axis
36
. A horizontal line or z-axis
38
also passes through the coordinate origin formed by the intersecting x- and y-axes. In the discussion which follows, it will be seen that the various anchor structures are constructed to restrict movement interfacially—wythe vs. wythe—along the z-axis and, in this embodiment, along the y-axis. The system
10
includes a masonry anchor
40
constructed for embedment in bed joint
24
and a facing anchor
42
constructed for embedment in bed joint
28
, including a low-profile, wire formative wall tie member
44
.
The masonry anchor
40
is shown in
FIG. 1
as being emplaced on a course of blocks
16
in preparation for embedment in the mortar of bed joint
24
. In the best mode of practicing the invention, a truss or reinforcement wire portion
46
is constructed of a wire formative with two parallel continuous straight wire members
48
and
50
spaced so as, upon installation, to each be centered along the outer walls of the masonry blocks
16
. An intermediate wire body or wire
52
is interposed therebetween and connects wire members
48
and
50
forming chord-like portions of the truss
46
. At intervals along the truss
46
, spaced pairs of transverse wire members
54
are attached thereto and are attached to each other by a rear leg
56
therebetween. These pairs of wire members
54
extend into the cavity
22
. As will become clear by the description which follows, the spacing therebetween is constructed to limit the x-axis movement of the construct. Each transverse wire member
54
has at the end opposite the attachment end an eye wire portion
58
formed continuous therewith. A sheetmetal loop is an alternative construction in lieu of eye wires shown in the best mode; however, the wire formative has been found to be structurally superior. Upon installation, the eye
60
of eye wire portion
58
is constructed to be within a substantially vertical plane normal to exterior surface
32
. The eye
60
is dimensioned to accept a wall tie threadedly therethrough and is thus slightly larger than the diameter of the tie. This relationship minimizes the y- and z-axis movement of the construct. For positive engagement, the eye
60
of eye wire portion
58
is sealed forming a closed loop.
The wall tie
44
is generally rectangular in shape and is dimensioned to be accommodated by a pair of eye wires
58
previously described. The wall tie
44
has a rear leg portion
62
, two parallel side leg portions
64
and
66
, and two front leg portions
68
and
70
. The front leg portions
68
and
70
are spaced apart at least by the diameter of the wire member
54
. An insertion portion
72
of wall tie
44
, upon installation, extends beyond cavity
22
into bed joint
28
, which portion includes front leg portions
68
and
70
and part of side leg portions
64
and
66
adjacent to front leg portions
68
and
70
. The longitudinal axes of leg portions
62
,
64
,
66
,
68
and
70
are substantially coplanar. The side leg portions
64
and
66
are structured to function cooperatively with the spacing of transverse wire members
54
to limit the x-axis movement of the construct.
The insertion portion
72
is considerably compressed and, while maintaining the same mass of material per linear unit as the adjacent wire formative, the vertical height
74
is reduced. The insertion end of the facing wall tie is a wire formative formed from a wire having a diameter substantially equal to the predetermined height of the mortar joint. Upon compressible reduction in height, the insertion end of the facing wall tie is mounted upon the exterior wythe positioned to receive mortar thereabout. The insertion end of the facing wall tie, usually the open end of wire wall tie, retains the mass and substantially the tensile strength as prior to deformation. The vertical height
74
of insertion portion
72
is reduced so that, upon installation, mortar of bed joint
28
flows around the insertion portion
72
. Upon compression, a pattern or corrugation
76
is impressed on insertion portion
72
and, upon the mortar of bed joint
28
flowing around the insertion portion, the mortar flows into the corrugations
76
. For enhanced holding, the corrugations
76
are, upon installation, substantially parallel to x-axis
34
. In this embodiment, the pattern
76
is shown impressed on only one side thereof; however, it is within the contemplation of this disclosure that corrugations or other patterning could be impressed on other surfaces of the insertion portion
72
. With wall tie
44
constructed as described, the wall tie is characterized by maintaining substantially all the tensile strength as prior to compression while acquiring a desired low profile.
The description which follows is of a second embodiment of the low-profile wall tie device. For ease of comprehension, where similar parts are used reference designators “100”, units higher are employed. Thus, the wall tie
144
of the second embodiment is analogous to the wall tie
44
of the first embodiment. Referring now to
FIGS. 4
to
6
, the second embodiment of a masonry construction system of this invention is shown and is referred to generally by the numeral
110
. As in the first embodiment, a wall structure
112
is shown having an interior wythe
114
of masonry blocks
116
and an exterior wythe
118
of facing brick
120
. Between the interior wythe
114
and the exterior wythe
118
, a cavity
122
is formed. Successive bed joints
124
and
126
are formed between courses of blocks
116
and the joints are substantially planar and horizontally disposed. Also, successive bed joints
128
and
130
are formed between courses of bricks
120
and the joints are substantially planar and horizontally disposed. Selected bed joint
124
and bed joint
128
are constructed to be interconnected utilizing the construct hereof; however, the joints
124
and
128
are unaligned. For purposes of discussion, the exterior surface
132
of the interior wythe
114
contains a horizontal line or x-axis
134
and an intersecting vertical line or y-axis
136
. A horizontal line or z-axis
138
also passes through the coordinate origin formed by the intersecting x- and y-axes. The system
110
includes a masonry anchor
140
constructed for embedment in bed joint
124
and, a facing anchor
142
constructed for embedment in bed joint
128
, including a low-profile wall tie member
144
.
The masonry anchor
140
is shown in
FIG. 4
as being emplaced on a course of blocks
116
in preparation for embedment in the mortar of bed joint
124
. In this embodiment, a ladder type reinforcement wire portion
146
is constructed of a wire formative with two parallel continuous straight wire members
148
and
150
spaced so as, upon installation, to each be centered along the outer walls of the masonry blocks
116
. An intermediate wire body or a plurality of wires
152
are interposed therebetween and connect wire members
148
and
150
forming rung-like portions of the ladder-type reinforcement
146
. At intervals along the ladder-type reinforcement
146
, spaced pairs of transverse wire members
154
are attached thereto and are attached to each other by a rear leg
156
therebetween. These pairs of wire members
154
extend into the cavity
122
. The spacing therebetween limits the x-axis movement of the construct. Each transverse wire member
154
has at the end opposite the attachment end an eye wire portion
158
formed continuous therewith. Upon installation, the eyes
160
of eye wire portion
158
are constructed to be within a substantially horizontal plane normal to exterior surface
132
. The eyes
160
are horizontally aligned to accept the pintles of a wall tie threaded therethrough from the unaligned bed joint. The eyes
160
are slightly larger than the diameter of the pintles, which dimensional relationships minimize the x- and z-axis movement of the construct. For ensuring engagement, the pintles of wall tie member
144
are available in a variety of lengths.
The low-profile wall tie or wire formative wall tie
144
is, when viewed from a top or bottom elevation, generally U-shaped and is, when viewed from right or left side elevation, is generally L-shaped. The low-profile wall tie
144
is dimensioned to be accommodated by a pair of eye wire portions
158
described, supra. The wall tie
144
has two rear leg portions or pintles
162
and
164
, two parallel side leg portions
166
and
168
, which are substantially at right angles and attached to the rear leg portions
162
and
164
, respectively, and a front leg portion
170
. An insertion portion
172
of wall tie
144
, upon installation extends beyond the cavity
122
into bed joint
128
, which portion includes front leg portion
170
and part of side leg portions
166
and
168
. The longitudinal axes of side leg portions
166
and
168
and the longitudinal axis of the contiguous portions of the front leg portion
170
are substantially coplanar. An insertion portion
172
of wall tie
144
, upon installation extends beyond the cavity
122
into bed joint
128
, which portion includes front leg portion
170
and part of side leg portions
166
and
168
.
The insertion portion
172
is considerably compressed and, while maintaining the same mass of material per linear unit as the adjacent wire formative, the vertical height
174
is reduced. The vertical height
174
of insertion portion
172
is reduced so that, upon installation, mortar of bed joint
128
flows around the insertion portion
172
. Upon compression, a pattern or waffle-like, cellular structure
176
is impressed on insertion portion
172
and, upon the mortar of bed joint
128
flowing around the insertion portion, the mortar flows into the cells
176
. For enhanced holding, the cells
176
are impressed on both sides of the insertion portion
172
; however, it is within the contemplation of this disclosure that cells or other patterning could be impressed on only one surface of the insertion portion
172
. With wall tie
144
constructed as described, the wall tie is characterized by maintaining substantially all the tensile strength as prior to compression while acquiring a desired low profile.
The description which follows is of a third embodiment of the masonry construction system. For ease of comprehension, where similar parts are used reference designators “200” units higher are employed. Thus, the wall tie
244
of the third embodiment is analogous to the wall tie
44
of the first embodiment.
Referring now to
FIGS. 7
to
9
, the third embodiment of the low-profile wall tie device is shown and is referred to generally by the numeral
210
. The veneer anchoring system
210
employs the pronged veneer anchor construction first described in U.S. Pat. No. 4,598,518 and marketed by Hohmann and Barnard, Inc., Hauppauge, N.Y. 11788 under the trademark “DW-10-X”. The dry wall structure
212
is shown having an interior wythe
214
with a wallboard
216
as the interior and exterior facings thereof. An exterior wythe
218
of facing brick
220
is attached to dry wall structure
212
and a cavity
222
is formed therebetween. The dry wall structure
212
is constructed to include, besides the wallboard facings
216
, vertical channels
224
with insulation layer
226
disposed between adjacent channel members
224
. The insulation layer
226
may optionally be mounted on the exterior surface of dry wall structure
212
. Selected bed joints
228
and
230
are constructed to be in cooperative functional relationship with the wall anchor described in more detail below. For purposes of discussion, the exterior surface
232
of the interior wythe
214
contains a horizontal line or x-axis
234
and an intersecting vertical line or y-axis
236
. A horizontal line or z-axis
238
also passes through the coordinate origin formed by the intersecting x- and y-axes. The system
210
includes a dry wall anchor
240
constructed for attachment to vertical channel members
224
and, a wall tie member
244
.
Reference is now directed to the construction of the wall anchor or pronged veneer anchor
240
comprising a backing plate member
246
and a projecting bar portion
248
. The projecting bar portion
248
is punched-out from the central portion of the stock plate member
246
so as to result in a centrally disposed aperture and, when viewed from the side elevation, a wall-tie-receiving slot
250
. The aperture is substantially rectangular configuration and is formed in the plate member
246
. The projecting bar portion
248
is thus disposed in substantially parallel relationship with respect to the plate member
246
; however, the upper and lower ends of the projecting bar portion
248
are slightly angled to permit the full projection of the bar portion
248
with respect to the plate member
246
. Secured to the upper and lower ends of the plate member
246
in a substantially perpendicular relationship are pronged end members
252
which are bifurcated to form prong portions or prongs
254
. It is within the present invention to have the end members
252
formed with a single prong; however, for structural purposes of the bifurcated construction is preferred. The plate member
246
is also provided with bores
256
at the upper and lower ends thereof, the purpose and function of which will be discussed in more detail hereinbelow. As is best seen in
FIG. 8
, the projecting bar portion
248
is sufficiently spaced from the plate member
246
so as to form a slot
250
therebetween which is adapted to receive the wall tie
244
therewithin. In the fabrication of the dry wall as the inner wythe of this construction system
210
, the channel members
224
are initially secured in place. In this regard, the channel members
224
may also comprise the standard framing members of a building. Sheets of exterior wallboard
216
, which may be of an exterior grade gypsum board, are positioned in abutting relationship with the forward flange
258
of the channel member
224
. While the insulating layer has herein been described as comprising a gypsum board, it is to be noted that any similarly suited rigid or flexible insulating material may be used herein with substantially equal efficacy. After the initial placement of the flexible insulation layer
226
and the wallboard
216
, the veneer anchors
240
are secured to the surface of the wallboard
216
in front of channel members
224
by forcing the prongs
254
therein until the prongs
254
abuttingly engage the front flange
258
of the channel members
224
. Thereafter, sheetmetal screws
260
are inserted into the bores
256
to fasten the anchor

.
The wall tie
244
is substantially a truncated triangularly shaped member and is dimensioned to be accommodated within slot
250
previously described. The wall tie
244
has a rear leg portion
262
, two divergent side leg portions
264
and
266
, and two parallel front leg portions
268
and
270
. To facilitate installation, the front leg portions
268
and
270
are spaced apart at least by the thickness of the projecting bar portion
248
. The longitudinal axes of leg portions
262
,
264
,
266
,
268
and
270
are substantially coplanar. The side leg portions
264
and
266
are structured to function cooperatively with the width of the projecting bar portion
248
to limit the x- and z-axis movement of the construct. An insertion portion
272
of wall tie
244
, upon installation, extends beyond the cavity
222
into bed joint
228
, which portion includes the front leg portions
268
and
270
and part of side leg portions
264
and
266
.
The insertion portion
272
is considerably compressed and, while maintaining the same mass of material per linear unit as the adjacent wire formative, the vertical height
274
is reduced. The vertical height
274
of insertion portion
272
is reduced so that, upon installation, mortar of bed joint
228
flows around the insertion portion
272
. Upon compression, a raised diamond, non-slip pattern
276
is impressed on insertion portion
272
and, upon the mortar of bed joint
228
flowing around the insertion portion, the mortar flows into the interstices diamond pattern
176
between the raised diamonds of the pattern
276
. For enhanced holding, the raised diamond pattern is shown on both sides thereof; however, it is within the contemplation of this disclosure that other patterning could be fashioned into the surfaces of the insertion portion
272
. With wall tie
244
constructed as described, the wall tie is characterized by maintaining substantially all the tensile strength as prior to compression while acquiring a desired low profile.
Because many varying and different embodiments may be made within the scope of the inventive concept herein taught, and because many modifications may be made in the embodiments herein detailed in accordance with the descriptive requirement of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
