No. 11/217,688, filed Sep. 2, 2005, which is a continuation in part of U.S. patent application Ser. No. 10/430,298, filed on May 7, 2003 (now U.S. Pat. No. 6,973,756), all of which are incorporated herein by reference in their entirety.


FIELD OF THE INVENTION
This invention relates to a connector for securing veneer to back-up walls.
BACKGROUND OF THE INVENTION
Many construction techniques have been developed for commercial buildings utilizing a back-up wall and a set of thin walled veneer panels that are supported on the back-up wall. Typically, there is a cavity between the veneer panels and the back-up wall to allow for the insertion of insulation and other materials. The veneer panels are connected to the back up wall using any of several different styles of connectors that are currently available. In addition to supporting the veneer panels, these connectors typically withstand various other loads, such as shear and wind loads.
Typically prior art connectors are relatively expensive to manufacture, and offer relatively poor load-bearing capacity for their weight and cost. One such prior art connector consists of an L-shaped member, and a veneer connector plate. The vertical portion of the L-shaped member is mounted to the back-up wall, and the horizontal portion extends outwardly therefrom. The horizontal portion typically includes slotted holes therethrough, for the mounting of the veneer connector plate thereon. The veneer connector plate extends outwards and supports at its outwardmost edge, a portion of a veneer panel.
For several reasons, these connectors are typically relatively expensive, and can add to the overall cost of erecting a building. One reason for their cost is that, to support the required loads during use, such connectors are typically required to be made from relatively thick materials. For example, for some applications, the L-shaped member is made from angle having a 3⁄8′′ wall thickness. Furthermore, many building codes require such connectors to be made from stainless steel, to resist corrosion and subsequent weakening or failure. Because of this materials requirement, the cost of the L-shaped member is increased substantially.
Furthermore, in order to cut 3⁄8′′ thick angle when making the L-shaped member, a sophisticated cutting device may be required, such as, for example, a plasma cutter. Plasma cutters are typically more expensive to operate than other cutting devices, and also, plasma cutter operators are more expensive than other cutting machine operators due to their relatively uncommon expertise.
A further issue driving the cost of prior art connectors is that, typically, they include at least two stainless steel bolts in their assembly, for example, to attach the veneer connector to the L-shaped piece. Stainless steel bolts are relatively expensive and can add significantly to the overall cost of the connector.
Accordingly, there is a need for a connector that is relatively inexpensive to manufacture, for use in supporting veneer panels.
SUMMARY OF THE INVENTION
According to one aspect, a connector for retaining at least one veneer panel on a back up wall is provided. The veneer panel may have a top edge and a bottom edge. The connector comprises a veneer connector and a support member. The support member comprises a mounting flange adapted for securing the support member to the back-up wall, and first and second support member side walls extending outwardly from the mounting flange. The first and second support member side walls define at least one generally horizontal surface when the support member is secured to the back-up wall. The veneer connector is securable to the horizontal surface by a mechanical fastener and is adapted to support a generally horizontal edge of the at least one veneer panel when the support member is secured to the back-up wall and when the veneer connected is supported by the generally horizontal surface. The connector is mountable on the back up wall such that the veneer connector supports one of the top and bottom edges of the at least one veneer panel.
The mounting flange may have an adjustment aperture therethrough. The adjustment aperture may be elongate and may be adapted to adjustably receive a fastener therethrough for mounting the support member to the back-up wall. The adjustment aperture may be generally vertical.
The generally horizontal surface may be provided by an upper surface of the first and second support member side walls.
The connector may further comprise a separate fastener for securing the veneer connector to the generally horizontally extending surface.
The veneer connector may comprise a section that abuts the veneer panel and is adapted to receive fasteners that engage the veneer panel.
According to another aspect, a connector for coupling a veneer panel to a back-up wall is provided. The connector comprises a support member comprising a mounting flange adapted for securing the support member to said back-up wall, and first and second support member side walls extending outwardly from the mounting flange. The first and second support member side walls define at least one generally horizontal slot when the support member is secured to the back-up wall. The connector further comprises a veneer connector configured for non-rotational sliding receipt in the generally horizontal slot and adapted to support a generally horizontal edge of said veneer panel when the veneer connector is received in the generally horizontal slot and when the support member is secured to the back-up wall.
The veneer connector may have a load transfer region for supporting the veneer panel, and the first and second support member side walls may extend outward from the mounting flange sufficiently to support the veneer connector proximate the load transfer region.
The veneer connector may have at least one veneer connector side wall. The veneer connector side wall may be generally vertical and may extend at least along a portion of the veneer connector that is unsupported by the support member.
The veneer connector may have a generally horizontal load transfer region for mounting to a horizontal edge of the veneer panel.
The generally horizontal slot may comprise a generally horizontal lower surface.
The mounting flange may comprise a first mounting flange portion and a second mounting flange portion. Each may have an aperture therethrough for mounting the support member to the back-up wall. At least one of the apertures may be positioned above the slot.
An elongate veneer connector adjustment aperture may be defined in the veneer connector. An elongate support member adjustment aperture may be defined in the support member. The support member adjustment aperture and the veneer connector adjustment aperture may extend generally perpendicularly to each other.
A veneer connector aperture may be defined in the veneer connector. A support member aperture may be defined in the support member. The support member aperture and the veneer connector aperture may be alignable with respect to each other for the pass through of a single mechanical fastener for securing the veneer connector to the support member.
The first and second side walls may be connected to each other by a side wall connecting portion. The first and second side walls may be joined together by a horizontal load support wall. The horizontal load support wall may be positioned at the top of the side walls.
The veneer connector may comprise a section that abuts the veneer panel and is adapted to receive fasteners that engage the veneer panel.

DETAILED DESCRIPTION OF THE INVENTION
Reference is made to FIG. 1, which shows a system of connectors 10 in accordance with a preferred embodiment of the present invention. Each connector 10 includes a veneer connector 12 for connecting with a veneer panel 14, and a support member 16 adapted for receiving the veneer connector 12 and for securement to a back-up wall 18. The connectors 10 may be made of any suitable material, such as 10 or 11 gauge stainless steel. The connectors 10 are preferably free of welds and formed from a single sheet of metal manufactured into the desired shape. The veneer panel 14 is may be a natural stone material, such as marble or granite. The veneer panel 14 may be a thin-walled panel, which is typically known as a thin masonry veneer panel, which many building codes require to be individually supported (i.e., each panel must be supported individually). It will be noted that the mortar that would typically exist between adjacent veneer panels 14 has been removed from the Figures for greater clarity.
The back-up wall 18 may be of form-poured concrete construction. Alternatively, the back-up wall 18 may be constructed of any suitable material, such as, for example, metallic studs, or block masonry. The veneer panels 14 may be spaced from the back-up wall 18 to provide a cavity 20 therebetween. Optionally, an insulation material 24 and a vapor barrier 26 may be installed in the cavity 20.
Reference is made to FIG. 2, which shows the veneer connector 12 in plan view. The veneer connector 12 may have a generally rectangular shape and has a first edge 28 and a second edge 30. An adjustment aperture 32 may be positioned adjacent the first edge 28. Referring to FIG. 5, the adjustment aperture 32 is used to receive a fastener 65 to join the veneer connector 12 to the support member 16. Referring to FIG. 2, the adjustment aperture 32 may be generally elongate to permit adjustment of the position of the veneer connector 12 within the support member 16, as will be discussed further below.
The veneer connector 12 includes a plurality of veneer connection apertures 34, which may be positioned proximate the second edge 30. The veneer connector 12 may include any suitable number of veneer connection apertures 34, such as, for example, three apertures 34, as shown in FIG. 2. Referring to FIG. 3, the veneer connection apertures 34 permit the pass-through of fastening ties 36 that extend from the edge of the veneer panel 14. The veneer connection apertures 34 may be generally circular, and may be sized to permit easy pass-through of the fastening ties 36, but are not required to be so large as to facilitate substantial adjustment of the veneer 14 relative to the veneer connector 12.
The veneer connection apertures 34 are positioned proximate the second edge 30 of the veneer connector 12 to prevent the unwanted protrusion of the second edge 30 past the outer face of the veneer 14. Thus, the second edge 30 can be buried in the mortar between vertically adjacent panels of veneer 14.
Referring to FIG. 2a, an alternative veneer connector 12′ is shown, which has a plurality of veneer connection apertures 34′ which are elongate to provide further adjustability of the veneer connector 12 with respect to the fastening ties 36.
Referring to FIG. 3, a securing means 40 prevents veneer 14 from disengaging from veneer connector 12. Securing means 40 may be any suitable means, such as, for example, a mechanical fastener or a weld.
The veneer connector 12 supports the veneer panel 14 (FIG. 1) during use generally in the region of the veneer connection apertures 34. The load imparted to the veneer connector 12 from the weight of the veneer panel 14 is shown at F.
Reference is made to FIG. 4, which shows the support member 16 in more detail. The support member 16 includes a mounting flange 42 and a support portion 44. The mounting flange 42 is adapted for mounting the support member 16 to the back-up wall 18 (FIG. 1). As shown, the mounting flange 42 is formed by a first mounting flange and a second mounting flange 48 (shown in FIG. 4)
The mounting flange 42 has an adjustment aperture 50 therethrough, which is adapted to receive a fastener 52, for fastening the support member 16 to the back-up wall 18 (FIG. 1). The adjustment aperture 50 may be generally elongate, as shown in FIG. 4, to permit adjustment of the support member 16 in the vertical direction. Such vertical adjustment capability facilitates aligning the support members 16 in a row on the back-up wall 18 (FIG. 1).
The mounting flange 42 also includes a securing aperture 54 therethrough, may be positioned on the second mounting flange 48, generally opposite the adjustment aperture 50. The securing aperture 54 is adapted for receiving a fastener 56 therethrough to further retain the support member 16 on the back-up wall 18 (FIG. 1), and to fix the position of the support member 16 therewith. Once the desired adjustment to the position of the support member 16 has been made using the fastener 52 and the adjustment aperture 50, the fastener 56 may be passed through the aperture 54 and into the back up wall 18 (FIG. 1), to fix the position of the support member 16.
Reference is made to FIG. 5, which shows the support portion 44 of the support member 16 more clearly. The support portion 44 extends from the mounting flange 42, and specifically, extends from the first mounting flange 46 and the second mounting flange 48, in a generally vertical plane denoted by the axes (y) and (z), and joins the first mounting flange 46 and second mounting flange 48 along two generally vertical lines which extend generally in the vertical (y) direction. By extending in a generally vertical plane, the support portion 44 is provided with a generally greater resistance to vertical bending forces, which result from the load F, that arise when the connector 10 supports a veneer panel 14 (FIG. 1). In other words, the configuration of the support portion 44 provides the support member 16 with a relatively high moment of inertia in the vertical (y) direction, compared to a typical L-shaped member used in connectors of the prior art.
The support portion 44 is made up of two spaced apart side walls 58, which are connected at their respective upper ends by a top portion 59. The top portion 59 and the spaced configuration of the side walls 58 provide resistance to bending loads that can occur in the lateral (x) direction during use. It is expected that any lateral loads will be smaller than the vertical loads incurred from the weight of the veneer 14 (FIG. 1). As a result, the moment of inertia in the lateral (x) direction may be smaller than that in the vertical (y) direction.
The top portion 59 can thus be referred to as a horizontal load support wall 59. As such it is not necessary for the horizontal load support wall 59 to be positioned at the top of the support member 16. For example, referring to FIG. 18, a support member 16′′′′′′ is shown, having a horizontal load support wall 132 positioned at the bottom of the two side walls 58. The support member 16′′′′′′ may otherwise be similar to the support member 16 (FIG. 5).
In the embodiments in FIG. 5, the horizontal load support wall 59 may be made contiguous such that the adjustment aperture 62 is not provided thereon. Instead the opposing end (i.e. the bottom end) of the side walls 58, which is not covered, may act as the adjustment aperture in the Z direction. Thus, the fastener 65 could mount between the open bottom end of the side walls 58 and the veneer connector 14. Similarly, in the embodiment in FIG. 18, horizontal support wall 132 may be made contiguous such that the adjustment aperture 62 is not provided thereon. Instead the opposing end (i.e. the top end) of the side walls 58, which is not covered, may act as the adjustment aperture in the Z direction. Thus, the fastener 65 (not shown in FIG. 18) 65 could mount between the open top end of the side walls 58 and the veneer connector 14.
Referring to FIG. 5, the side walls 58 are advantageously joined together by the horizontal load support wall 59. However, the horizontal load support wall 59 could be omitted, as shown in the embodiment shown FIG. 19. FIG. 19 shows a support member 16′′′′′′ that has a contiguous flange portion 136. The side walls 138 extend outwards from the flange portion 136 and are joined to the flange portion along generally vertical, spaced apart lines. The side walls 138 could be joined to the flange portion by any suitable means, such as, for example, welding.
Referring to FIG. 5, the side walls 58 together define a slot portion 60, which may extend in a generally horizontal (x-z) plane, for receiving and supporting the veneer connector 12. The slot 60 permits the lateral adjustment of the veneer connector 12 in both the (x) direction and in the z direction. The slot 60 is made sufficiently deep so that the veneer connector 12 is supported along a substantial portion of its length. More particularly, the support portion 44 extends outwards to support the veneer connector 12 proximate its load supporting region, i.e. the region about the apertures 34 where the load F is imparted to the veneer connector 12 by the veneer panel 14 (FIG. 1). This reduces bending stresses on the veneer connector 12 in use when supporting a veneer panel 14 (FIG. 1).
The slot 60 is preferably positioned proximate the upper ends of the side walls 58, to reduce its impact on the overall moment of inertia of the support portion 44 in the vertical (y) direction. It will be noted that the slot 60 may extend in a plane that is other than horizontal. For example the slot 60 may be angled generally downwards towards its blind end, so that the veneer connector 12 may be retained in place temporarily without the use of a fastener.
An adjustment aperture 62 may be defined in the upper portion 59, for receiving the fastener 65 therethrough. The fastener 65 may pass through the adjustment aperture 62 and the adjustment aperture 32 in the veneer connector 12 for fixedly retaining the veneer connector 12 in place in the support member 16. The adjustment aperture 62 may be generally elongate, and may extend in a direction that is generally perpendicular the aperture 32 in the veneer connector 12. In this way, the apertures 62 and 32 cooperate to provide adjustment for the veneer connector 12 within the slot 60 in both the (x) and (z) directions.
The fastener 65 may be any suitable type of fastener. For example, the fastener 65 may be made up of a stainless steel hex-head bolt 65a, a washer 65b, and a nut 65c. The hex head bolt 65a extends upwards from under the veneer connector 12, and is sized so that the side walls 58 capture the head of the bolt 65a and prevent it from rotating. The threaded end of the bolt 65a passes up and through the adjustment aperture 62 on the support member 16. The washer 65b and nut 65c are positioned on the exposed end of the bolt 65a and are tightened to provide a secure connection between the support member 16 and the veneer connector 12. By having captured the bolt 65a between the side walls 58, the task of installing the fastener 65 is facilitated. It will be noted that other types of bolts and other types of fasteners altogether could alternatively be used to connect the support member 16 and the veneer connector 12.
Reference is made to FIG. 5a, which shows an alternative washer 65b′ that can be used as part of the connector 65. The washer 65b′ may have a generally arcuate shape in side view and extends downwards to capture the side walls 58 of the support member 16. When the nut 65c is tightened, the washer 65b′ captures and pushes together the side walls 58, further strengthening their capture of the head of the bolt 65a. Thus, as the tightening force on the nut 65c is increased, the capturing force of the side walls 58 on the bolt 65a is increased, inhibiting the bolt 65a from rotating as a result of the increased tightening force.
It will be noted that the washer 65b′ may have any suitable shape for pushing the side walls 58 together. For example, the washer 65b′ may alternatively have an inverted V-shape in side view instead of an arcuate shape. Furthermore, the washer 65b′ may have any shape in plan view. For example, the washer 65b′ may have a generally circular shape or may alternatively have a rectangular shape so that it better captures the side walls 58.
Reference is made to FIG. 6a, which shows a plate 70 which may be used to manufacture the support member 16 (FIG. 1). The plate 70 may be machined with a plurality of apertures and slots which will ultimately form the slot 60, the aperture 62 and the mounting apertures 50 and 54. Furthermore, a slot 72 may be machined into the plates 70, to remove unnecessary material. Once the plate 70 is machined with the appropriate slots and apertures, it may be bent into the shape of the support member 16 by two primary bending operations. The first bending operation bends the two tabs shown at 74 and 76 along a bend line 78, resulting in the structure 79 shown in FIG. 6b. The tabs 74 and 76 will ultimately form the mounting flange 42 (FIG. 4). The second bending operation involves folding the plate 70 generally about a fold line. The folding of the plate 70 may be performed on a radiused surface thereby forming the upper portion 59 and the spaced apart side walls 58. Manufacturing the support member 16 in this way saves cost and manufacturing time while providing a relatively strong resulting structure. It will be noted that the order of operations described is preferable, but may alternatively be rearranged in any suitable way.
By making the support member 16 by appropriately machining and by applying two simple bends to the single, integral plate 70, the cost of manufacture for the support member 16 are reduced, relative to complex structures of the prior art which are made from multiple pieces which are welded together.
Reference is made to FIG. 1, which shows the connector 10 in use. In use, a plurality of connectors 10 are used to support a plurality of panels of veneer 14 in a spaced relationship from the back up wall 18 of a structure such as an office tower. The support members 16 are mounted to the back-up wall, and may be spaced from each other in a generally horizontally and vertically extending array. The veneer connectors 12 are positioned in the slots 60 (FIG. 5), and extend therefrom to support the veneer panels 14. The fastening ties 36 (FIG. 3) extend between vertically adjacent veneer panels 14 and pass through the veneer connection apertures 34, which retain the panels 14 in place. Furthermore, mortar may be used to close any air gap adjacent veneer panels 14, and to assist in retaining the panels 14 in place. The vertical load F that results from the weight of the veneer panels 14 is supported by the veneer connectors 12, and in turn, by the support members 16. Because the support members 16 have generally high moments of inertia in the vertical direction, they are able to be made with relatively thin gauge material for supporting the load imposed thereon by the veneer panels 14. It will be noted that while two connectors 10 are shown along the top edge of each veneer panel 14, any suitable number of connectors 10 may be used to support each veneer panel 14, depending on the nature of the specific application.
Reference is made to FIG. 7, which shows a veneer connector 12′′′, which may be used alternatively to the veneer connector 12. The veneer connector 12′′′ may be similar to the veneer connector 12 (FIG. 2), or the veneer connector 12′ (FIG. 2a), except that the veneer connector 12′′′ has a pair of side webs 84 that extend vertically from the side edges of the veneer connector 12′′′. The side webs 84 may extend generally along substantially the entire length of the veneer connector 12′′′, except for the portion 86 of the veneer connector 12′′′ that will be embedded within the gap between adjacent veneer panels 14 (FIG. 1). The side webs 84 provide increased bending resistance to the veneer connector 12′′′, relative to the veneer connector 12 (FIG. 2), because the side webs 84 generally increase the moment of inertia of the veneer connector 12′′′.
Reference is made to FIG. 8, which shows a support member 16′ that maybe used as an alternative to the support member 16 (FIG. 4). The support member 16′ may be similar to the support member 16, except that the support member 16′ has a slot 90 that positioned closer to the bottom of the support member 16′, relative to the slot 60 on the support member 16 (FIG. 4). The slot 90 may otherwise be similar to the slot 60, and is for receiving and retaining the veneer connector 12 or 12′′′ (FIGS. 2 and 2a). Referring to FIG. 8a, the slot 90 is positioned sufficiently low, so that, when the support member 16′ is being mounted to the back-up wall 18 proximate the top edge of a veneer panel 14, the veneer panel 14 does not completely obstruct access to the adjustment aperture and the securing aperture, which are shown at 92 and 94 respectively. Thus, the relatively lower position of the slot 90 facilitates the mounting of the support member 16′.
Reference is made to FIG. 9, which shows a support member 16′′, which is another alternative to the support member 16. The support member 16′′ may be similar to the support member 16, except that the support member 16′′ has an adjustment aperture 98 that is elongate along an angle A from the vertical. The adjustment aperture 98 in the embodiment shown in FIG. 9 provides vertical adjustability for the support member 16′′, in a similar way to the adjustment aperture 50 on the support member 16 (FIG. 4). During vertical adjustment of the support member 16′′, however, the support member 16′′ will be shifted by a certain amount horizontally. Preferably, the angle A from the vertical is small, to reduce the horizontal shift that occurs during vertical adjustment of the support member 16′′. Referring to FIG. 10, a support member 16′′′ may also be made which has an adjustment aperture 98′ that is a mirror image of the adjustment aperture 98 (FIG. 9).
The support member 16, as shown in FIG. 5, has a support portion 44 that extends generally orthogonally outwards from the plane of the mounting flange 42. It is, however, possible for the support portion 44 to extend outwards from the mounting flange 42, at an angle such that it is not orthogonal to the mounting flange 42, as shown in FIG. 14. In the support member 16′′′′ of the variant shown in FIG. 14, the side walls 58 of the support portion 44 are supported along generally vertical lines by the mounting flange 42 and thus have a greater resistance to bending under a vertical load imposed thereupon, relative to a typical L-shaped member used in connectors of the prior art. This is true even though the side walls 58 extend outward from the mounting flange 42 at an angle such that they are not orthogonal to the mounting flange 42.
The side walls 58 of the support portion 44 are shown in FIG. 5 as being supported along vertical lines by the mounting flange 42. It is not necessary that the support be provide along strictly vertical lines however. Referring to FIG. 15, the support member 16′′′′ is advantageous relative to L-shaped members of the prior art, even though the side walls 58 are not strictly vertical, and are supported by the mounting flange 42 along lines that are off of vertical by some small amount. Throughout this disclosure and the accompanying claims, the term “generally vertical” is meant to include lines or planes that are strictly vertical and those that are off of vertical within a selected range. While the selected range is preferably small so that the side walls 58 are relatively close to vertical, the range could alternatively be relatively large while still providing a structure that is advantageous relative to L-shaped connectors of the prior art. For example, the range could be as large as 45 degrees off of vertical in each direction.
Reference is made to FIG. 16, which shows a connector 110, in accordance with another embodiment of the present invention. The connector 110 includes a support member 16′′′′′′ and a veneer connector 12′′. The support member 16′′′′′′ may be similar to the support member 16 (FIG. 4), except that the support member 16′′′′′′ supports the veneer connector on its upper surface, shown at 116, instead of supporting the veneer connector 12′′ in a slot.
The upper support wall 116 may be made generally planer to assist in supporting and stabilizing the veneer connector 12′′. The adjustment aperture 62 is provided in the upper support wall 116. The upper support wall 116 extends between the two spaced apart side walls 118. The side walls 118 may be similar to the side walls 58, shown in the support member 16, shown in FIG. 5. The upper support wall 116, thus acts as the horizontal support for the side walls 118.
The veneer connector 12′′ rests on top of the upper support wall 116. The veneer connector 12′′ has the adjustment aperture 32 which is alignable with the adjustment aperture 62 on the support member 16′′′′′′ when the veneer connector is positioned on the upper support wall 116. The adjustment aperture 32 is generally perpendicular to the adjustment aperture 62 in order to provide adjustability for the veneer connector 12′′ on the support member 16′′′′′′ in two orthogonal directions in a horizontal plane.
Referring to FIG. 17, the fastener 65 may be provided for joining the veneer connector 12′′ to the support member 16′′′′′′. The fastener 65 may include the hex head bolt 65a, the washer 65b, the nut 65c, and a washer 65d. The washers 65b and 65d are provided to inhibit the pulling through of the bolt 65a or nut 65c through the adjustment apertures 62 and 32 during assembly and use of the connector 110.
Referring to FIG. 16, the veneer connector 12′′ includes the veneer connection apertures 34, positioned proximate its second, or outside, edge 30. The veneer connection apertures 34 may include a centre aperture 34a and two outer apertures 34b. The centre aperture 34a may be generally circular while the outer apertures 34b may be slotted to provide flexibility in receiving imperfectly positioned fastening ties 36 (FIG. 3) on the veneer panels 14 (FIG. 3).
The veneer connector 12′′ may include a pair of side webs 120, which may be similar to the side webs 84 on the veneer connector 12′′′, as shown in FIG. 7.
The veneer connector 12′′ may include one or more strengthening ribs 121 on its upper surface 122. The strengthening ribs 121 provide additional vertical bending resistance for the central region of the veneer connector 12′′ which is spaced relatively far away from the side webs 120. By positioning the strengthening ribs 121 on the upper surface 122, they do not create an interference hazard when mounting the veneer connector 12′′ on the support member 16′′′′′′. Like the side webs 120, the strengthening ribs 121 must be positioned so as not to obstruct the connection of the veneer connector 12′′ with the veneer panel 14 that will ultimately sit above it (see FIG. 3).
Referring to FIG. 11, the support members 16′′ and 16′′′ may be manufactured from a common plate 100. The common plate 100 may be similar to the plate 70 (FIG. 6a), except that the common plate 100 has an aperture therein, that will ultimately become the adjustment aperture 98 (FIG. 9), or the adjustment aperture 98′ (FIG. 10), depending on which way the plate 100 is folded during manufacture. For example, referring to FIG. 12a, the tabs on the plate 100, which are shown at 104 may be folded in a first direction, so that the plate 100 will ultimately form the support member 16′′. However, referring to FIG. 12b, the tabs 104 may be folded in a second direction that is opposite the first direction, so that the plate 100 ultimately forms the support member 16′′′.
Reference is made to FIG. 13, which shows a system of connectors 106 and 108, which cooperate in pairs to support veneer panels 14. The connectors 106 and 108 may be similar to the connector 10 (FIG. 1), and include a suitable veneer connector, such as the veneer connector 12. However, the connectors 106 and 108 include the support members 16′′ and 16′′′ respectively, instead of the support member 16 (FIG. 1).
The top and bottom edges of the panel 14 are supported by at least one of each connector 106 and 108. As a result, the weight of the panel 14 is prevented from dragging the connectors 106 and 108 down the wall 18, because the adjustment apertures extend in different directions. Thus, because the adjustment apertures 98 and 98′ are not parallel to each other when the connectors 106 and 108 are installed on the back-up wall and are in use, the adjustment apertures 98 and 98′ cooperate with their respective fasteners and with each other to prevent the connectors 106 and 108 from being dragged down from their supported load.
It will be noted that more than one of each connector 106 and 108 may be used to support an edge of the veneer panel 14. For example, several of one type of connector, e.g. connector 106 and one or two of the other type of connector, eg. connector 108, may be used to support an edge of the veneer panel 14. At least one of each connector 106 and 108 is used, however.
It will be noted that the features shown in the support members disclosed herein may all be combined into a support member in accordance with the present invention in any desired way. For example, a support member may be provided that includes the basic structure of support member 16, but that has a low-positioned slot, similar to the slot 90 of support member 16′ (FIG. 8), and that also has a slanted adjustment aperture, similar to the adjustment aperture 98 or 98′ of support members 16′′ and 16′′′ (FIGS. 9 and 10). Similarly, the features shown in the veneer connectors disclosed herein may all be combined into a veneer connector in accordance with the present invention in any desired way.
In the embodiments described above, the side walls of the support members have been described and shown as extending outwardly from the mounting flanges along vertical planes. It will be noted that the vertical planes need not be strictly vertical, but are at least generally vertical. In another alternative, the side walls of the support members need not be strictly planar, and may instead be curved or may have further folds, which are preferably generally vertical.
In the embodiments described above, the veneer connector mounts to the support member using a single fastener, such as a bolt. Using a single fastener instead of a plurality of fasteners can provide a significant cost savings in the overall cost of the connector, particularly in jurisdictions which require the use of stainless steel for connectors supporting veneer panels in a cavity wall.
The connectors of the present invention are able to support the same loads as the L-shaped connectors of the prior art, but can be manufactured from thinner material, with fewer fasteners. As a result the connectors of the present invention can be less expensive than the L-shaped connectors of the prior art.
While what has been shown and described herein constitutes the preferred embodiments of the subject invention, it will be understood that various modifications and adaptations of such embodiments can be made without departing from the present invention, the scope of which is defined in the appended claims.
