Description

    FIELD OF THE INVENTION
  • [0001]
    The present invention relates generally to a wire tie and hardware system. More particularly, the present invention relates to a wire tie, and a hardware system having a wire tie and an anchor, for supporting a masonry veneer to a structural support element.
  • BACKGROUND
  • [0002]
    Masonry veneer walls must be supported by attachment to an inner structural support element. The attachment must be sturdy to support the weight of the masonry veneer, but also must allow for some flexibility and sealing so that wind, temperature changes, and other environmental conditions do not cause cracking or other damage the veneer wall.
  • [0003]
    U.S. Pat. No. 4,473,984, issued to Lopez, and U.S. Pat. No. 4,764,069, issued to Reinwall et al., each disclose hardware systems for attaching a masonry veneer to a structural support element. The systems in these patents include a threaded anchor secured to the support element, and a wire tie. The wire tie engages an aperture in the anchor at one of its ends, and the wire tie is submerged within the mortar of the masonry veneer wall at its other end. The wire tie has some degree of flexibility in its engagement with the anchor, thereby allowing for easier installation and for preventing damage to the masonry veneer, while still providing adequate support and establishing a positive lateral load connection between the veneer wall and the support element.
  • [0004]
    U.S. Pat. No. 4,875,319, issued to Hohmann, also discloses a hardware system for attaching a masonry veneer to a structural support element. The hardware system in the Hohmann patent is specifically adapted for use in seismic zones. The system includes an anchor plate attached to a structural wall, a triangular wire tie attached to the anchor and to the veneer, and a clip member and rod member for providing further stability.
  • [0005]
    One problem with the hardware system disclosed in these patents is that the relatively closed shape of the triangular wire tie prevents it from being easily inserted into the aperture of the anchor during construction of the veneer wall. Another problem with the triangular-shaped wire tie is that the horizontal movement of the masonry veneer is somewhat reduced, thereby subjecting the veneer to possible damage when it expands or contracts due to environmental conditions. One solution to these problems was to provide a new shape of the wire tie, a so-called “Single Wire Tie,” manufactured by Heckmann Building Products, Inc. of Chicago, Ill. However, while the Single Wire Tie allowed for easier insertion and for horizontal movement of the veneer, it does not meet building codes in some jurisdictions.
  • [0006]
    Accordingly, there remains a need for an improved wire tie and hardware system for supporting masonry veneer walls.
  • SUMMARY

  • DETAILED DESCRIPTION
  • [0018]
    Referring now to the drawings, and initially to FIG. 1, a wire tie according to one embodiment of the present invention is shown generally at 10. The wire tie 10 is formed as a unitary wire body 12. The wire body 12 is preferably a metal, and in the most preferred embodiments, the wire body 12 is hotdip galvinized steel, mill galvanized steel, epoxy coated steel, or stainless steel. Before bending, the wire body 12 preferably is about 8-¼ to 35-{fraction (1/4×)} inches long, more preferably about 10-¼ to about 24-¼ inches long, and most preferably about 12-¼ to 18-¼ inches long. The wire body 12 preferably has a generally circular cross-section throughout, with a diameter of about ⅛ to ¼ inch, and more preferably, about {fraction (3/16)} inch. However, other cross-sections, such as rectangular cross-sections, may also be used.
  • [0019]
    The wire body 12 is bent into a plurality of portions integrally connected with each other, including a pair of central portions 14 and 16, a loop portion 28, a pair of flange portions 36 and 38, and a pair of reverse extension portions 42 and 44. The central portions 14, 16 have first ends 18, 20, respectively, which are connected with each other by the loop portion 28. The second ends 22, 24 of the respective central portions 14, 16 are connected with respective flange portions 36, 38. The reverse extension portions 42, 44 are connected with each respective flange portion 36, 38, at an end opposite the end to which the respective central portions 14, 16 are connected.
  • [0020]
    In the preferred embodiment, the central portions 14, 16 are substantially parallel to each other and generally have the same length. Preferably, the central portions 14, 16 are about 2 to 6 inches in length, more preferably about 3 to 5 inches in length.
  • [0021]
    The flange portions 36, 38 extend outwardly in opposite directions from one another and are non-parallel with their respective central portions 14, 16. Preferably, the flange portions 36, 38 are substantially perpendicular to their respective central portions 14, 16. The flange portions 36, 38 are preferably about 1 to about 5-½ inches in length, more preferably about ¾ to about 2 inches in length, and most preferably about 1 inch.
  • [0022]
    The reverse extension portions 42, 44 generally extend from the flange portions 36, 38 back towards the end of the wire tie 10 having the first ends 18, 20 of the central portion 14, 16 and the loop portion 28. In the preferred embodiment of the invention, the reverse extension portions 42, 44 are substantially perpendicular to their respective flange portions 36, 38 and are generally parallel to the central portions 14, 16. Preferably, the reverse extension portions 42, 44 are about ½ inch to about 2 inches in length, and most preferably about ⅝ inch.
  • [0023]
    The loop portion 28 preferably is formed from three discrete portions, including leg portions 30, 34, and connecting portion 32. However, in alternate embodiments, the loop portion may be formed from a continuous curve, an inverted V-shape, or an inverted U-shape. Preferably, leg portions 30 and 34 are substantially perpendicular to the connecting portion 32. In the preferred embodiment, the leg portions 30, 34 each are about ¾ to about 2 inches, more preferably about 1 to about 1-½, and most preferably about 1-{fraction (1/4)} inches. In the preferred embodiment, the connecting portion 32 is about ½ to about 2 inches, more preferably about 1 to about 1-½, and most preferably about 1-¼ inches.
  • [0024]
    The central portion 14, the flange portion 36, and the reverse extension 42 generally define a J-shape, while the central portion 16, the flange portion 38, and the reverse extension 44 generally define a reverse J-shape. The central portions 14, 16, the flange portions 36, 38, and the reverse extension portions 42, 44 generally are co-planar and thus define a wire tie plane. In contrast, the loop portion 28 is not co-planar with the wire tie plane. In the preferred embodiment, the loop portion 28 is substantially perpendicular to the wire tie plane.
  • [0025]
    Referring now to FIGS. 2 and 3, a hardware system according to the present invention is shown generally at 48. For purposes of illustration, the hardware system 48 is shown in the drawings in one of its particular uses, for establishing a positive lateral load connection between an outer masonry veneer wall 110 and an inner structural supportive element 120. In the embodiment shown, the masonry veneer wall 110 is formed by masonry units 112 and 114, such as bricks, stones, or concrete blocks, which are joined to one another by mortar 116 or other cementitious material. In the embodiment shown, the inner structural supportive element 120 is covered by sheathing 130 on the surface 122 facing the masonry veneer 110. However, in alternate embodiments, the supportive element 120 may not be covered by a sheathing. In the embodiment shown, the inner structural supportive element 120 is a concrete wall, a steel beam, a concrete masonry unit, or a steel or wooden support stud.
  • [0026]
    The hardware system 48 includes the wire tie 10 and an anchor 98. Suitable anchors for use with the hardware system of the present invention are sold by Illinois Tool Works, Inc. of Glenview, Ill., under the trade name Tapcon® screw, and by Elco Industries, Inc. of Rockford, Ill., under the trade name Dril-It® screw. Other suitable anchors are disclosed in U.S. Pat. Nos. 4,473,984 and 4,764,069, both of which are incorporated herein by reference in their entireties. Briefly, the anchors suitable for the hardware system 48 include a threaded portion 50, a barrel portion 70, and a head portion 80. In the embodiment shown in FIGS. 2 and 3, the threaded portion 50 includes a central metal shank 52 formed with a self-drilling tip 54 and formed with a self-tapping machine thread 56. When the threaded portion 50 is driven by being rotated and advanced axially, the tip 52 drills through the sheathing 130 and the structural element 120 and then the thread 54 screws and secures itself into the structural element 120. The threaded portion 50 is zinc electro plated steel, coated twice and baked in STALGARD®, a modified polyester copolymer sold by Elco Industries, Inc. of Rockford, Ill.
  • [0027]
    The barrel portion 70 is generally cylindrical in shape and is formed integrally with an outer driving head portion 80 which, in the embodiment shown, is in the form of a flat, axially projecting tongue of generally rectangular shape and generally rectangular cross-section. The barrel portion 70 and the head portion 80 are preferably die cast from a zinc-aluminum alloy. A suitable zinc-aluminum alloy is Zamac 2, a 92% zinc alloy sold by Grand Rapids Alloy Inc. of Grand Rapids, Mich. The barrel portion 70 is sized according to the thickness of the sheathing 130. Preferably, the barrel portion 70 is about ½ to about 3 inches in length. Typicaly barrel portion lengths are ⅝ inch, 1 inch, 1-½ inches, 2 inches, and 2-½ inches.
  • [0028]
    An axially extending threaded hole 72 is formed in the distal end of the barrel portion 70 and is sized to receive the outer end portion of a second threaded shank (not shown) of the threaded portion 50, which is separated from the first shank by flange 58. The threaded portion 50 is screwed snugly into the barrel portion 70 by hand before the threaded portion 50 is driven. During driving of the threaded portion 50, the barrel portion 70 drills through the sheathing 130 and forms an enlarged counterbore which receives the barrel portion 70 in the finally installed position of the threaded portion 50. The flange 58 formed between the two threaded shanks of the threaded portion 50 engages the outer side 122 of the support element 120 and the inner end of barrel portion 70 when the threaded portion 50 is filly tightened.
  • [0029]
    The barrel portion 70 also preferably includes cutting elements 76 which are uniquely shaped so as to enable the barrel portion 70 to drill a counterbore effectively through the sheathing 130. The head portion 80 preferably includes an enlarged, radially extending and circular flange 86 formed integrally between the tongue 82 and the barrel portion 70. When the anchor 98 is fully driven, the inner face of the flange 86 seats tightly against the outer side 132 of the sheathing 130 and thus serves as a washer to close off and seal the counterbore in the sheathing 130. For the flange 86 to effectively close off the counterbore, the diameter of the flange 86 should be significantly greater than the diameter of the barrel portion 70. In one specific embodiment of the anchor, the barrel portion 70 has a diameter of about ⅜″, while the flange 86 has a diameter of about ¾″.
  • [0030]
    An aperture 84 (FIG. 3) is formed transversely through the driving tongue 82. The aperture 84 is sized and adapted to receive a portion of the wire tie 10. As shown in FIG. 3, the aperture 84 is generally oblong in shape and is oriented with its long edges extending parallel to and with its short edges extending transversely of the outer free end of the tongue 82.
  • [0031]
    The wire tie 10 and the aperture 84 are sized and adapted so that the wire body 12 may be inserted through the aperture 84, and manually manipulated so that the wire tie 10 generally is positioned relative to the head portion 80 such that the loop portion 28 extends through the aperture 84. Preferably, the wire tie 10 will be positioned such that one of the leg portions 30 or 34 will extend through the aperture 84. Thus, after the anchor 98 has been driven, the wire tie 10 is hooked through the aperture 84, manipulated into position, and then is placed in the wet mortar 116. Typically, at least 2 inches of the central portions 14 and 16, as well as the flange portions 36 and 38, and the reverse extension portions 42 and 44 will be set into the mortar 116. The length of the leg portion 30, 34 allows for some vertical adjustment during installation without allowing for excess mechanical play and deformation. When the mortar 116 sets up, the hardware system 48 forms a positive lateral load connection between the masonry veneer wall 110 and the inner supportive element 120.
  • [0032]
    The reverse extension portions 42, 44 significantly increase the magnitude of the pullout load that the wire tie 10 can withstand after it is installed. Without the reverse extension portions 42, 44, a relatively smaller pullout load would cause the flange portions 36, 38 to straighten relative to (run parallel to) the central portions 14, 16, and allow the wire tie 10 to be forcibly removed from the mortar 116. The reverse extension portions 42, 44 act to inhibit this straightening of the flange portions 36, 38, and therefore a relatively larger pullout load is needed to remove the wire tie 10 from the mortar 116.
  • [0033]
    FIGS. 4-7 illustrate an alternate embodiment of a wire tie and hardware system according to the present invention. The wire tie 210 is substantially similar to the wire tie 10 (FIG. 1), but does not include leg portions or a vertical loop, and thus is generally planar. The wire tie 210 is formed from a unitary wire body 212 that is bent into a plurality of portions integrally connected with each other, including a pair of central portions 214 and 216, a connecting portion 228, a pair of flange portions 236 and 238, and a pair of reverse extension portions 242 and 244. The central portions 214, 216 have first ends 218, 220, respectively, which are connected with each other by the connecting portion 228. The second ends 222, 224 of the respective central portions 214, 216 are connected with respective flange portions 236, 238. The reverse extension portions 242, 244 are connected with each respective flange portion 236, 238, at an end opposite the end to which the respective central portions 214, 216 are connected.
  • [0034]
    In the preferred embodiment, the central portions 214, 216 are substantially parallel to each other and generally have the same length. The flange portions 236, 238 extend outwardly in opposite directions from one another and are non-parallel with their respective central portions 214, 216. Preferably, the flange portions 236, 238 are substantially perpendicular to their respective central portions 214, 216. The reverse extension portions 242, 244 generally extend from the flange portions 236, 238 back towards the end of the wire tie 210 having the first ends 218, 220 of the central portion 214, 216 and the connecting portion 228. In the preferred embodiment of the invention, the reverse extension portions 242, 244 are substantially perpendicular to their respective flange portions 236, 238 and are generally parallel to the central portions 214, 216.
  • [0035]
    The portions of the wire tie 210 have the same preferred ranges of dimensions as their corresponding portions in the wire tie 10 (FIG.1). The central portion 214, the flange portion 236, and the reverse extension 242 generally define a J-shape, while the central portion 216, the flange portion 238, and the reverse extension 244 generally define a reverse J-shape.
  • [0036]
    The wire tie 210 of the embodiment of FIGS. 4-7 is preferably used in a hardware system specifically designed for use in reducing damage to masonry veneers due to seismic events. As shown in FIG. 4, seismic hardware system 248 includes the wire tie 210 and an anchor 298. In especially preferred embodiments, the hardware system also includes one or more bracket members 260 (FIG. 5), as described more thoroughly below.
  • [0037]
    The anchor 298 includes a backing plate member 272 and a wire retaining member 274. The wire retaining member 274 is preferably punched out from the central portion backing plate member 272 so as to result in a centrally disposed aperture 276. The wire retaining member 274 is thereby disposed in substantially parallel, spaced, but integral relationship with respect to the backing plate member 272. In alternate embodiments, the plate member 272 and wire retaining member 274 are not integral, but rather are made from entirely different pieces. An elongated passage 286 is formed between the wire retaining member 274 and the backing plate member 272 for securing the wire tie 210 in the horizontal direction (towards the veneer 310, FIG. 6), while allowing for some minimal play in the lateral direction, and for extensive slideability in the vertical direction. The backing plate member 272 includes structural element engaging portions 278, 280 provided with bores 282, 284, respectively, for attaching the anchor 298 to a structural element. The anchor 298 is preferably made from 10 to 20 gauge sheet metal, and more preferably, about 12 to 16 gauge sheet metal. The anchor 298 is preferably about 1 to 2 inches wide and about 4 to 8 inches long, and more preferably, about 1-¼ to 1-½ inches wide and 5 to 7 inches long. An especially preferred anchor is the Screw-On Anchor Plate, Part No. 315-D, manufactured by Heckmann Building Products Inc. of Chicago, Ill.
  • [0038]
    In alternate embodiments of the invention, the anchor may not include a backing plate member, and instead includes an elongated strip of metal bent into structural element engaging portions and a wire retaining member. A suitable anchor according to this alternate embodiment of the invention is the Screw-On Anchor Strap, Part No. 315-C, manufactured by Heckmann Building Products, Inc. of Chicago, Ill.
  • [0039]
    Referring now to FIG. 6, the hardware system 248 is shown in the drawings in one of its particular uses, for establishing a positive lateral load connection between an outer masonry veneer 310 and an inner structural supportive element 320. In the embodiment shown, the masonry veneer wall 310 is formed by masonry units 312 and 314, such as bricks, stones, or concrete blocks, which are joined to one another by mortar 316 or other cementitious material. In the embodiment shown, the inner structural supportive element 320 is a concrete wall, a steel beam, a concrete masonry unit, or a steel or wooden support stud.
  • [0040]
    The anchor 298 is attached to the structural element 320 by the fasteners 288. The fasteners suitable for attachment to the structural element 320 are chosen based upon the nature of the structural element. After the anchor 298 has been attached, the wire tie 210 is hooked through the elongated passage 286, manipulated into position, and then is placed in the wet mortar 316. As shown in FIG. 7 (in which masonry unit 312 has been removed for clarity), preferably at least 2 inches of the central portions 214 and 216, as well as the flange portions 236 and 238, and the reverse extension portions 242 and 244, will be set into the mortar 316.
  • [0041]
    As shown in FIG. 7, the hardware system 248 preferably also includes one or more bracket members 260. The bracket members 260 are preferably made from 18 to 26 gauge sheet metal, and most preferably 22 gauge sheet metal. The bracket members 260 include a base portion 262, a tab portion 264 stamped out from the base portion 262, and a flange portion 266 preferably bent perpendicular to the base portion 262. The flange portion 266 includes an aperture 268 (FIG. 5) sized and adapted to receive a reverse extension portion 242 or 244 of the wire tie 210. The tab portion 264 is adapted and sized to engage an elongated rod member 269. The elongated rod member 269 extends through the mortar 316 and between all bracket members 260 for all wire ties 210 in the respective masonry unit layer of the masonry veneer. The elongated rod member 269 adds stability to the masonry veneer and protects against potentially damaging seismic events, and is usually required by building codes in seismic zones.
