Title: Brick tie anchor

Description:
The present invention relates to masonry anchor members for tying a masonry veneer to a stud back-up in a cavity wall and more particularly to the provisions of anchor members which can be quickly installed to project at precisely the right distance from the back-up stud while requiring substantially less material than conventional anchor members, and still more particularly to anchor members as aforesaid which will not be subject to or will have a greatly increased resistance to corrosion. 
     BACKGROUND OF THE INVENTION 
     Cavity walls of a masonry veneer tied to a backup wall are commonly utilized in construction to provide for an aesthetically pleasing appearance while being less expensive than solid masonry walls. One common type of cavity wall used in both residential and commercial buildings is a brick veneer tied to a stud back-up wall. 
     The brick veneer is tied to the stud back-up wall by use of masonry or brick veneer anchors. Such anchors are generally a planar anchor plate which is attached to the stud of the stud back-up wall. The anchor plate at the exposed end is provided with a slot through which a brick tie wire is inserted, the brick tie wire being mortared between two rows of bricks to provide a secure connection between the brick veneer and back-up wall. As there are a large quanitty of connectors required to secure the brick veneer their cost becomes a very critical factor. In the past, these connectors have been made of a galvanized carbon steel which is a material similar to that which is used in the construction of the metal studs for the stud back-up walls. 
     While it is highly desirable to provide for the proper location of the anchor plates so that the slotted exposed ends stand at the correct distance proud of the back-up wall, the commonly utilized means for effecting such location has necessitated added plate material increasing costs. As a result some anchor plates have eliminated any locating means and have to be set in position simply by sight giving rise to inaccurate tie wire embeddments. In addition, there has recently been serious concern expressed by a number of agencies regarding the potential for corrosion and failure of the masonry anchors due to the exposure of the anchors to moisture which is present in the cavity between the stud back-up wall and the masonry veneer. 
     One widely used example of a connector which provides for accurate presentation of the slotted exposed end of the anchor plate is an L-shaped connector plate with the base of the “L” fitting over the face edge of the stud and the leg of the “L” being connected to the main part of the stud and having a slot for a brick tie wire in a nose portion of the plate extending beyond the front edge of the stud. By constructing the anchor in such a shape, various sizes of anchors for various sizes of studs, such as “4”, “6” and “8” inch studs, may be constructed. While such an anchor plate is hugely successful, it requires a significant quantity of material which increases with stud size giving rise to increasing costs. 
     SUMMARY OF THE INVENTION 
     The present invention in one aspect provides for an anchor member for an anchor tie for tying courses of masonry veneer to a backup wall of sheet material supported by spaced vertical studs which anchor members can be easily installed to project at precisely the right distance from the back-up wall while requiring substantially less material than conventioanl anchor members. 
     In another aspect, the invention provides for an anchor plate as aforesaid which utilizing the reduced material requirement of the invention augment by the increased strength of stainless steel adding to the size reduction, can be economically made of stainless steel to compete with conventional anchors having locating means thereby eliminating the problems of anchor plate corrosion. 
     More particularly, the anchor plate or member of the invention, which to take full advantage of the invention is formed of stainless steel, has a nose portion adapted to be projected through a vertical slit in a backup wall sheet material, and an anchor portion to extend rearwardly of the sheet material and to be secured to a stud supporting the sheet material. 
     The nose portion of the anchor plate which has a tie wire slot formed therein, has a maximum vertical dimension for maximum adjustability such that the length of the tie wire slot is not greater than approximately the height of a veneer course. The horizontal dimension of the nose portion is sufficient to present the tie wire slot standing proud of the backup wall sheet material at precisely the desired distance when the anchor plate is installed. 
     The anchor portion of the anchor plate has a maximum horizontal dimension not greater than approximately one-half of the width of the smallest studs usually encountered in back-up walls. The anchor portion of the plate is provided with a locating abutment means projecting perpendicular thereto to engage a backup wall surface to fix the projection of said anchor nose portion beyond the backup wall sheet material at precisely the desired distance. 
     In another aspect, in a preferred form the present invention provides for an anchor member comprising a generally planar anchor plate having an outer coupling nose or end for connection to a veneer tie wire and an inner anchoring portion or end for securement to the back-up wall. The anchor plate has struck-out tabs extending laterally thereof intermediate the coupling end and the anchoring end. The outer coupling end is insertable through a slot cut through the back-up wall insulating sheet material adjacent a supporting stud until the tabs engage the inner face of the sheet material to provide for proper spacing of the coupling end from the back-up wall. 
     In still another aspect, the invention provides for a tool engaging ledge arrangement struck out from the anchoring end of the anchor plate whereby the plate can be held with a tool such as a screwdriver inserted beneath the ledge arrangement when it is being fastened to a stud.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention in one aspect is directed to a masonry anchor member or plate and, in particular, to a brick veneer anchor plate for use in tying a brick veneer wall to a stud back-up wall. According to this aspect of the invention, the anchor plate required a minimum amount of material for cost savings while at the same time incorporating means for easily installing same to project at precisely the correct distance forwardly of the back-up wall. 
     In another aspect the present invention is directed to an anchor member or plate as aforesaid which will eliminate the problem of corrosion presently experienced by the exposure of the anchor member to the environment of the moisture collecting cavity between the brick veneer and the back-up wall. 
     In still another aspect of the invention, as a consequence of reducing the size of the anchor, it has also been found desirable to provide for ways and means for easy installation of the anchor to the stud of the back-up wall. This has been accomplished in preferred embodiments of the invention with the use of holding means adapted for holding the anchor in position while allowing the installer to attach the anchor to the stud of the stud back-up wall. 
     According to the preferred form of the invention the utilization of the principal of anchor size reduction is coupled with the use of stainless steel as the material of the anchor plate. The use of stainless steel gives the desired corrosion resistance while at the same time its increased strength over the standard galvanized steel enables the additional reduction in anchor size without loss of tie holding power. As a result, the preferred form of this invention has enabled the conventional corrosion susceptible anchors to be replaced by corrosion resistant anchors without added cost, while at the same time enabling such anchors to incorporate means for their accurate installation. 
     A first preferred embodiment of a masonry anchor according to the present invention is illustrated in FIGS. 1 through 4. The masonry anchor of this embodiment is particularly of use as a brick veneer anchor and is shown in the figures generally indicated by the numeral  10 . Brick veneer anchor  10  is attached to a stud  12  of a stud back-up wall  14  to tie a brick veneer wall  16  constructed of a number of courses of individual bricks  18  to the back-up wall  14 . Bricks  18  are mortared together by use of mortar  20  to form the brick veneer wall  16 . Brick veneer wall  16  is spaced from the stud back-up wall  14  to provide an intermediate air space or cavity  22 . 
     As illustrated in FIGS. 1 and 2, stud wall  14  is comprised of a plurality of studs  12  to which an outer covering  26  is attached. During construction of the stud back-up wall  14  the studs  12  are placed in position and then the outer covering  26  is attached to the studs  12  to form the stud back-up wall  14 . A number of slots  24  are cut in the outer covering  26  adjacent the studs  12  to provide for openings through which the brick veneer anchor  10  may be inserted as will be described below. 
     Brick veneer anchor  10  is comprised of a generally planar body or anchor plate manufactured from stainless steel to resist the corrosion effects of the environment of the cavity  22 . Anchor  10  has an outer coupling nose or end  30  having a vertically extending slot  34  for connection to a veneer tie wire  32  and an inner anchoring end  36  for securing the anchor  10  to the stud  12 . Outer coupling end  30  has a width sufficient to project the vertically extending slot  34  beyond the outside surface of the back-up stud wall  14 . This dimension would depend upon the thickness of any covering  26  attached the the stud back-up wall  14 . Generally, the coupling end  30  would project the slot  34  at least 0.5″ into the cavity  22  beyond the wall surface. For a wall covering  26  of about 0.5 inch or where there is no wall covering on the stud back up wall  14 , the coupling end  30  is generally about 1.5 inches in width and the slot  34  is located about 0.5 inch in from the front edge of the coupling end  30 . For wall coverings  26  of about 1.5 to 2 inches, the width of the coupling end  30  would generally be about 3 inches with the slot  34  again located about 0.5 inch in from the front edge of the coupling end  30 . 
     The vertically extending slot  34  has a maximum vertical dimension approximately equal to the height of the brick  18  and has a horizontal dimension to allow the tie wire  32  to pass through. The dimensioning of the vertically extending slot  34  allows for adjustability of the positioning of the tie wire  32  in relation to the anchor  10  to allow for adjustment based on the location of the brick courses of the brick veneer wall  16 . Brick tie wire  32  extends from the coupling end  30  to lie between two courses of bricks  18  in the brick veneer wall  16 . After the tie wire  32  is properly positioned as shown in FIG. 1, it is mortared between the two courses of bricks  18  of the brick veneer wall  16 . In this way, the brick veneer wall  16  is securly tied or connected to the stud back-up wall  14 . 
     It will be considered that the height of the nose portion  30  which accomodates the tie wire slot  34  will depend on the amount of vertical ajustment required to meet variations in the mortaring of the brick veneer. For example, when erecting buildings or shopping malls, the care taken to ensure the eveness of the mortaring is much less than when erecting multiple sotry buildings such as apartment buildings where the spacing between floors is preceise. Thus, for multiple story buildings such as apartment buildings the tie wire adjustments can be less requiring smaller anchors. 
     As practical expamples for a 3 inch brick course providing for a full course adjustment the height of the nose portion  30  would be of the order of 4 inches and the length of the slot  34  would be of the order of 3 inches. 
     Where this degree of adjustment is not required the height of the nose piece  30  for example could be 3 inches with the length of the slot  34  being 2¼ inches. Again, as another example, for a nose portion  30  having a height of 2 inches, the length of the slot would preferrably be 1¼ inches. 
     The brick veneer anchor  10  is provided with an anchoring end distal of the coupling end for securing the anchor  10  to the stud  12  of the stud back-up wall  14 . In order to provide for proper positioning of the brick veneer anchor  10  relative to the stud  12  to provide for the proper exposure of the coupling end  30  and the slot  36 , the anchor  10  is provided with locating abutment means projecting perpendicular thereto. In the embodiment illustrated, the locating abutment means are struck-out tabs  40  which, when the anchor is inserted through the slot  24  the outer covering  26 , rest against the rear surface of the outer covering  26 . Once the anchor  10  is in this proper position, it may be attached to the stud  12  of the stud back-up wall  14  by suitable means, such as sheet metal screws  42  for metal studs  12  or wood screws for wood studs. 
     The brick veneer anchor  10  is relatively small in order to reduce the amount of material used while still providing sufficient area for proper securement to the stud  12 . Generally, the horizontal dimension of the anchoring end  36  of the anchor  10  is no more than one half the width of the stud  12 . For a “4” inch stud which is actually 3.625 inches in width, the anchoring end  36  is 1.75 inches or less in width, preferrably 1.5 inches in width. For a “6” or “8” inch stud  12 , the anchoring end  36  is preferrably 1.75 inches in width. 
     As the anchoring end  36  is relatively small, it could be difficult for the installer to hold the anchor in the proper position and at the same time attach it to the stud  12 . In order to make it easier for an installer to hold the anchor  10  in position, the anchor  10  is preferably provided with a holding means  44  for holding the anchor  10 . The holding means  44  preferably allows for the anchor to be held in position either by hand or by use of a suitable tool, such as a screw driver or a tool specially adapted for holding of the anchor. In the preferred embodiment of the masonry anchor  10  as illustrated in FIGS. 1 through 4, the holding means  44  is adapted to permit holding of the anchor  10  either by hand or by use of a screwdriver  46  or a specially adapted tool  48 . This is accomplished by providing the holding means  44  with a an upstanding ledge formation shown as a strap  50  which is struck out of the planar body of the anchor  10 . Ledge formation or strap  50  is spaced laterally from the body of the anchor  10  to provide for a space between the underside thereof and the body of the anchor  10  sized to permit the end of a flat blade screwdriver  46  to be inserted into the opening as illustrated in FIG.  4 . This permits the installer to hold the anchor  10  in position using the screwdriver  46  with one hand, and then use the other hand to drive the screws  42  through the anchor  10  and into the stud  12 . Preferably, to accommodate the end of the screwdriver  46 , strap  50  has a slight wedge or trapezoidal shape with the front having a reduced width relative to the back of the strap  50  and hence the opening between the strap  50  and the body of the anchor  10  is also wedge shaped. 
     In order to allow the anchor  10  to be held by hand rather than through use of a screwdriver  46  or tool  48 , the holding means  44  for holding the anchor  10  is preferably provided with a second part, namely, a struck out tab  52  which extends perpendicular from the back end of the strap  50 . This tab  52  allows for griping of the tab  52  by the fingers of the installer so that the installer may hold the anchor in the proper position for insertion of the screws  42  through the anchor  10  and into the stud  12 . 
     FIG. 5 illustrates a second embodiment of a brick veneer anchor of the present invention which is a variation of the first embodiment. Similar to the first embodiment, brick veneer anchor  10 A is comprised of a generally planar body or anchor plate constructed of a stainless steel material having an outer coupling end  30 A for securing the anchor  10 A to a stud  12 . Outer coupling end  30 A is provided with the vertically extending slot  34   a  dimensioned as in the first embodiment. Anchor  10 A is provided with locating enbuttment means namely, struck-out tabs  40   a , intermediate the outer coupling end  30 A and the inner anchoring end  36   a . Masonry veneer anchor  10 A is also provided with holding means for holding the anchor  10 A by use of a suitable tool such as a screwdriver or the tool  48  specially adapted for holding the anchor  10 A. In contrast to the first embodiment, holding means  44 A comprises a split strap  50 A. This construction of the strap  50 A is particularly suitable for use with material which is less malleable and which may not have the properties to permit for the strap and holding tab to be struck out, similar to the first embodiment. Split strap  50 A is formed by first making an H-shaped cut within the body of the anchor  30 A. The two tabs formed by the H-shaped cut are then pushed out to form the split strap  50 A. FIG. 5 illustrates the use of the special tool  48  adapted to allow for proper positioning of the anchor  10 A for attachment to the stud or the stud back-up wall. This tool  48  is also usable with the first embodiment of the masonry anchor  10  illustrated in FIGS. 1 to  4 . 
     As illustrated in FIG. 5, the tool  48  has a first generally planar portion  54  with a second portion  56  attached to the rear edge of the first portion  54  generally perpendicular to the first portion  54  to form a generally L-shaped tool. The dimension of the first portion  54  is selected such that when the tool  48  is attached to the anchor  10  or  10 A, the dimension between the tabs  40  or  40 A of the anchor  10  or  10 A and the second portion  56  is the same as the depth of the stud  12  of the back-up wall  14 . Thus, tools adapted for different sizes of studs, such as “4”, “6” or “8” inch studs, may be provided. The forward edge of the tool  48  is provided with a centrally extending tongue  58  which has a means  60  for engaging with the holding means  44  or  44 A by insertion into the spacing or gap between the strap  50  or  50 A and the body of the anchor  10  or  10 A. The front edge of the tool  48  on either side of the forwardly extending tongue  58  is provided with shoulders  62  which are displaced slightly out of the plane of the first portion  54  to allow the shoulders  62  to engage with the rearward edge of the anchor  10  or  10 A when the tool is releasably attached to the anchor  10  or  10 A. In order to allow for almost hands free installation of an anchor  10  or  10 A constructed of hot dip galvanized steel using the tool  48 , the tool  48  may be provided with magnetized regions which can be utilized to releasably hold the anchor  10  or  10 A to the tool  48 , as well as releaseably hold the tool  48  to a metal stud  12  if the anchor  10  or  10 A is being installed on a metal stud back-up wall  14 . Thus, magnetized regions may be provided on the interior face of the forwardly extending tongue  58  to releasably hold a hot dip galvanized anchor  10  or  10 A to the tool  48  as well as on the interior face of the second portion  56  or the first portion  54  to releaseably hold the tool  48  and its attached anchor  10  or  10 A to a metal stud  12 . Anchors  10  or  10 A constructed of stainless steel are generally non-metallic. In these circumstances, the shoulder  62  of the tool  48  may be provided with a gripping means to grip the anchor  10  or  10 A so that it may be properly held by the tool  48 . Alternatively, the means  60  for engaging with the holding means  44  or  48 A may be dimensioned to provide for a tight friction fit between the holding means  44  or  44 A and means  60  on the tool. Once the anchor  10  or  10 A has been attached to the metal stud  12 , the tool  48  is easily removed from the anchor  10  or  10 A by breaking the magnetic contact. By utilizing the magnetized regions to hold the anchor  10  or  10 A and tool  48  in position the installer has both hands free to properly attach the anchor  10  or  10 A to the stud  12  and it is not necessary for them to hold the anchor  10  or  10 A in position for attachment to the stud  12 . Thus, the installer could hold a screw gun in one hand and could use the second hand for placing the screw  42  in the proper position or for withdrawing screws  42  from a pouch or holder. 
     A third embodiment of a masonry anchor according to the present invention is shown in FIGS. 6 through 9 generally indicated by the numeral  70 . Similar to the first embodiment, masonry anchor  70  is comprised of a generally planar body or anchor plate constructed of stainless steel or other corrosion resistant material having an outer coupling end  72  for connection to a veneer wire tie  32  and an inner anchoring end  74  for securing the anchor  70  to a stud  12 . Outer coupling end  72  is dimensioned to project beyond the front surface of the back up wall  14  and is provided with a vertically extending slot  76 , dimensioned to allow the wire tie  32  to pass through, and to provide for the adjustability of the positioning of the wire tie  32  relative to the brick courses  18  in the brick veneer wall  16 . 
     Similar to the first embodiment, anchor  70  is attached to a stud  12  of a the stud back-up wall  14  by use of suitable screws  78 . Anchor  70  is provided with locating abutment means, namely, struckout tabs  80 , intermediate the outer coupling end  72  and inner anchoring end  74  to butt against the outer covering  24  of the stud back-up wall  14  to properly position the anchor  70  so that the outer coupling end  72  is properly exposed beyond the covering wall  24  for insertion of the wire tie  32 . In contrast to the first and second embodiments, third embodiment of the anchor  70  is not provided with any means for easily holding the anchor  70 . Rather, the anchor  70  utilizes a special tool  82  which holds the anchor  70  in position against the stud  12  for easy attachment of the anchor  70  to the stud  12  by use of screws  78 . 
     In the preferred embodiment illustrated in the figures, tool  82  has a generally paddle shaped body  84  having a handle  86  for griping in the hand of the installer. The interior base of the paddle shaped body  84  is provided with a recessed or cut out region  88  dimensioned to accept the body of the anchor. Preferably in order to releaseably hold the body of a hot dipped galvanized anchor  70  within the recessed or cut out region  88 , the recessed or cut out region  88  is provided with one or more magnetized areas  90  which magnetically hold the body of the anchor  70  within the recessed or cutout region  88 . Thus, the anchor  70  may be placed within the recessed or cut out region  88  and then the installer utilizes the tool  82  to which the anchor  70  is attached to insert the outer coupling end  72  of the anchor  70  through the slot  26  in the wall  14 . For use with an anchor  70  of non-magnetic stainless steel, the edges of the recessed or cut-out region  88  may be provided with gripping means to releaseably grip the edges of the anchor  70 . Once the anchor has been installed to the wall, the tool may easily be removed, releasing the anchor  70  from the gripping means. Another way of holding the anchor  70  to the tool  82 , when the anchor is constructed of stainless steel, would be to provide on the front face of the tool a strap or other means for holding the struck-out tab  80  to the front face of the tool. The tool  82  is provided with holes  92  which line up with the holes  70  for the screws. These holes  92  thereby provide guides for the installer to utilize the screws  78  to attach the anchor  70  to the stud  12 . Once the anchor  70  has been attached to the stud  12 , the magnetic contacts of the magnetized region  90  of the anchor  70  or the releaseable connection by the gripping means are broken to thereby release the tool  82  from its attachment to the anchor  70 . 
     In order to permit hands-free installation of the anchor  70  in a proper position for attachment to the stud  12 , the inner base of the paddle shaped body  84  may be provided with additional magnetized regions  94  which will magnetically couple the tool  82  and the attached anchor  70  to the stud  12 . To increase the magnetic coupling of the tool  82  to the stud  12 , the paddle shaped body  84  is preferably provided with a perpendicular extension  96  extending from the interior of the body  84  to provide for an L-shaped interior portion which matches the dimension of the stud  12 . Perpendicular extension  96  may also be provided with suitable magnetic regions  98  to increase the releaseable attachment of the tool  82  and the anchor  70  to the stud  12 . 
     While different sizes of tools  82  may be provided for different sizes of studs, such as “4”, “6” or “8” inch studs, it is also possible to provide for a tool  84  which is adjustable for use with different size studs. The connection between the perpendicular extension and the paddle shaped body  84  may be provided as a slideable connection to allow for the perpendicular extension  96  to be moved to vary the dimension of the L-shaped interior portion. In this way, the tool is easily adapted for use of different sizes of studs. 
     The installation of this embodiment of a masonry anchor  70  is illustrated in FIGS. 6 through 9. The anchor  70  is initally releasably attached to the recessed opening  88  of the tool  82  by means of the magnetic regions  90  or gripping means. As shown in FIG. 8, the tool  82  and the attached anchor  70  are then slid forward to insert the outer coupling end  72  of the anchor  70  through the slot or opening  26  in the outer covering  24  of the stud back-up wall  14 . Once the anchor  70  and tool  82  are in the proper position, screws  78  are inserted through the openings  92  to attach the anchor  70  to the stud  12 . The tool  82  may then be removed from the anchor  70  by breaking the magnetic contacts between the tool  82  and the anchor  70  and the stud  12 . 
     The embodiment of the brick veneer anchor  70  illustrated in FIGS. 6 through 9 is also easily adaptable for use in those rare circumstances when the anchor  70  is being installed on a stud back-up wall  12  which does not have an outer cover. In these circumstances, the anchor  70  is flipped over so that the locating abuttment means and the struck-out tabs  80  butt against the outer edge of the stud  12 . In these circumstances, the anchor may be easily held in place, either by hand, or by use of the tool. The second embodiment of the anchor as illustrated in FIG. 5 may also be easily adapted for use in stud back-up walls without an outer covering. In those circumstances, the installer could easily hammer down the split strap  50 A to flatten it to the plane of the anchor and then flip over the anchor so that the struck-out tabs  40 A would abutt the forward edge of the stud  12 . 
     A fourth embodiment of a masonry anchor according to the present invention is illustrated in FIGS. 10 through 12, generally indicated by the numeral  100 . This anchor  100  is a two-part anchor having a forward part  102  which contains the outer coupling region with the associated slot  104  for engagement of the wire tie. This forward part  102 , being the part of the anchor  100  which is exposed to the cavity  22  and the moisture contained in the cavity, is constructed of a material having increased resistence to the corrosive effects of the moisture encountered within the cavity  22 . Such a material is typically a stainless steel or other corrosive resistant material. The rear part  106  being contained within the stud back-up wall  14  and not being exposed to the moisture may be constructed of a less expensive material, such as a carbon steel. The two parts  104  and  106  are connected to one another by suitable means, such as for example, metal stitching  108 . Anchor  100  is also provided with the locating abutment means for properly fixing the projection of the coupling end beyond the front surface of the back up wall  14 . In the embodiment illustrated, the second part  106  has a generally L-shaped dimension to correspond to the depth of the stud  12  to act as the locating abutment means. To install the anchor  100 , the coupling end is inserted through the slit in the covering  26  of the back up wall  14  and the anchor  100  pushed forward until the leg of the L shaped second part  106  encounters the outer edge of the stud. As the second portion  106  fits easily around the stud, it is a simple matter to hold the anchor  100  in position and insert the suitable screws  110  into the anchor as is shown in FIG.  12 . The tie wire  32  is then connected to the outer coupling  102  end in this manner during the laying of the brick courses of the brick veneer wall. 
     The present invention provides for a masonry anchor, and in particular, a brick veneer anchor for tying a brick veneer wall to a stud back-up wall. The anchor has increased resistance to the corrosive effects of the environment contained within the cavity wall, while at the same time being economical to manufacture and relatively easy to install. The use of the anchor of the present invention provides for an increased life of the anchor in that the moisture which is contained within the cavity will not adversely effect the integrity and strength of the anchor through corrosion. 
     Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
