The present disclosure generally relates to a facade support system used in building construction, and more specifically, to a veneer tie used to connect an outer wall member to an inner wall member of a wall.
A facade can be a durable and aesthetically desirable construction for a building exterior. Facades, such as brick or stone veneer walls, also provide protection to the interior of the building from the surrounding environment. Anchoring systems are used to secure facades (e.g., outer wythes) to inner wall members (e.g., inner wythes, stud frame walls, etc.) of a building to overcome forces which might pull the facade away from the building. These anchoring systems extend from the inner wall of the building to the facade. Generally, anchoring systems include veneer ties connected to the inner wall member with a wall anchor. The wall anchor is coupled to the veneer tie and is secured to the inner wall member, thereby attaching the veneer tie to the inner wall member. The veneer tie is embedded in a mortar bed joint of the facade to attach the veneer tie to the facade. Wall reinforcement may also be placed in and extend along the mortar bed joint of the facade and be connected to the veneer tie to strengthen the mortar bed joint, the facade and the connection between the mortar bed joint and the veneer tie.
In one aspect, a veneer tie is used in a wall to join an inner wall member and an outer wall member of the wall. The outer wall member is formed from a plurality of successive courses of masonry units with a mortar-filled bed joint between each two adjacent courses. The veneer tie has an installation axis configured to extend generally perpendicular to the outer wall member when the veneer tie is being used to join the inner wall member to the outer wall member. The veneer tie comprises an attachment portion configured to be attached to a wall anchor used to secure the veneer tie to the inner wall member. The veneer tie also comprises an insertion portion coupled to the attachment portion and configured for disposition in the bed joint. The insertion portion includes a first recess and a second recess. The first recess is disposed at a first location on the insertion portion and the second recess is disposed at a second location on the insertion portion. The first and second locations are spaced apart from one another in a direction parallel to the installation axis of the veneer tie. The first and second recesses each being configured to receive a reinforcement member of a wall reinforcement.

Referring to
The outer wall member 12 has successive bed joints 22 filled with mortar formed between courses of masonry units 24 (e.g., bricks, stone, CMUs, etc.) and are substantially planar and horizontally disposed. The bed joints 22 are specified as to the height or thickness of the mortar layer and the thickness specification is adhered to so as to provide the requisite uniformity for quality construction. In accordance with building standards, the bed joints 22 are approximately 0.375 inches (0.9525 cm) in height in a typical embodiment. However, bed joints 22 of different heights are within the scope of the present disclosure. Select bed joints 22 receive a veneer tie 110 of the anchoring system 100 which extends from the bed joint 22 across the cavity 20 and is connected to the exterior surface 18 of the inner wall member 14. The anchoring system 100 includes a wall anchor 102 secured to the inner wall member 14 which couples the veneer tie 110 to the inner wall member. In this way, the veneer tie 110 anchors the outer wall member 12 to the inner wall member 14. In this embodiment, the wall anchor 102 is a folded wall anchor, further details of which may be found in U.S. Pat. Nos. 7,845,137 and 7,562,506, the entireties of which are hereby incorporated by reference.
The anchoring system 100 also includes wall reinforcement 104 for disposition in the bed joint 22, specifically the same bed joint at the veneer tie 110. The wall reinforcement 104 extends along the length of the wall in the bed joint 22 to reinforce and strengthen the bed joint. In the illustrated embodiment, the wall reinforcement 104 is a ladder type wall reinforcement that is embedded in the mortar of the bed joint 22 and generally overlies and/or underlies the veneer tie 110 in the bed joint. The ladder type wall reinforcement 104 has opposite first and second reinforcement members or legs 106 and 107, respectively. The first and second reinforcement members 106, 107 are generally parallel to one another and extend along the entire length of the wall reinforcement 104. Transverse (e.g., third) reinforcement members 108 extend between and interconnect the first and second reinforcement members 106, 107 at set intervals along the length of the wall reinforcement 104. The transverse reinforcement members 108 are generally perpendicular to the first and second reinforcement members 106, 107. Referring to
The veneer tie 110 is configured to couple to the wall anchor 102 and the wall reinforcement 104. Referring now also to
The insertion portion 114 is coupled or fixed to the attachment portion 112. The insertion portion 114 is configured for disposition in a bed joint 22. The insertion portion 114 generally extends outward in a direction from the attachment portion 112. As shown in
In the illustrated embodiment, the insertion portion 114 includes first and second segments 122, 124 each extending from opposite ends of the rear segment 116 of the attachment portion 112. The insertion portion 114 also includes first and second free end segments 126, 128 extending from ends of the first and second segments 122, 124, respectively. The first and second free end segments 126, 128 generally extend toward and along one another in a direction generally perpendicular to the installation axis IA. The first and second end segments 126, 128 are generally parallel to one another and spaced apart to define a gap 130 therebetween sized and shaped to receive a portion of the wall reinforcement 104. The gap 130 is open at one end and closed at the other end by the first segment 122. Portions of the first and second end segments 126, 128 are bent upward and disposed in a horizontal plane above the rest of the insertion portion 114 so that the end segments extend along and brace each side of the portion of the wall reinforcement 104 received in the gap 130 when the wall reinforcement overlies the insertion portion to link and join the veneer tie 110 and wall reinforcement together.
The insertion portion 114 includes a plurality of recesses 132, each recess configured to receive the wall reinforcement 104 when the wall reinforcement overlies the insertion portion. In particular, each recess 132 is arranged and sized and shaped to receive one of the first and second reinforcement members 106, 107 of the wall reinforcement 104. In the illustrated embodiment, the insertion portion 114 includes three recesses 132A, 132B, 132C (e.g., first, second and third recesses), although the insertion portion may include more or fewer recesses. In the illustrated embodiment, each recess 132 is swaged to correspond to the arcuate cross-sectional shape of the first and second reinforcement members 106, 107, although other shapes are within the scope of the present disclosure. The recesses 132 are disposed at locations on the insertion portion 114 where the wall reinforcement 104 crosses the insertion portion 114. In the illustrated embodiment, at least two of the recesses 132 are disposed at different locations (e.g., different longitudinal locations) on the insertion portion 114 which correspond to the different locations the first and second reinforcement members 106, 107 will cross the insertion portion. For example, the first recess 132A is disposed at a first location on the insertion portion 114. This first location is on the first segment 122 and corresponds to the location where the second reinforcement member 107 crosses the first segment. Likewise, the second recess 132B is disposed at a second location on the insertion portion 114. This second location is on the first segment 122 and corresponds to the location where the first reinforcement member 106 crosses the first segment. Thus, the first and second locations are spaced apart from one another in a direction parallel to the installation axis IA of the veneer tie 110. This spacing corresponds to the arrangement of the first and second reinforcement members 106, 107, which are spaced apart relative to the installation axis IA of the veneer tie 110. In this embodiment, the first and second recesses 132A, 132B are axially aligned with one another (e.g., are arranged such that an imaginary line extending therebetween is generally parallel to the installation axis IA). In addition, the second recess 132B (e.g., the second location) is laterally aligned with the gap 130 (e.g., are arranged such that an imaginary line extending therebetween is generally perpendicular to the installation axis IA) which also receives the first reinforcement member 106. In the illustrated embodiment, the third recess 132C is disposed at the first location (e.g., is laterally aligned with the first recess 132A) on the insertion portion 114 and is laterally spaced apart from the first recess. Broadly, the third recess 132C or any additional recesses can be laterally spaced apart from one of the first or second recess 132A, 132B so that the third or additional recesses receive the same reinforcement member 106, 107 of the wall reinforcement 104 that the first or second recess receives. The third recess 132C is disposed on the second segment 124 at the location that corresponds to where the second reinforcement member 107 crosses the first segment. It is understood that recesses 132 can be placed at generally any intersection point between the veneer tie 110 and the wall reinforcement 104.
The recesses 132 further link and join the veneer tie 110 and wall reinforcement 104 together, strengthening the connection between the two, which may be necessary for certain building applications (e.g., seismic construction). In this manner, the veneer tie 110 is coupled to the wall reinforcement. In addition, the recesses 132 reduce the overall or combined thickness or height H of the veneer tie/wall reinforcement assembly. In the illustrated embodiment, the combined height H (see,
In operation, the wall anchor 102 is used to secure the veneer tie 110, via the attachment portion 112, to the inner wall member 14. The insertion portion 114 is in a substantially horizontal plane with the bed joint 22. The insertion portion 114 extends across the cavity 20 into the bed joint 22. The first and second segments 122, 124 extend from the attachment portion 112 across the cavity 20 and into the bed joint 22. The wall reinforcement 104 extends along the bed joint 22 and overlies the insertion portion 114 and is disposed within the recesses 132 and gap 130 of the veneer tie 110. The wall reinforcement 104, the first and second free end segments 126, 128 and a portion of each of the first and second segments 122, 124 are surrounded by (e.g., embedded within) the mortar and secured within the bed joint 22.
Other configurations of the anchoring system 100 (e.g., veneer tie 110, wall anchor 102, wall reinforcement 104) are within the scope of the present disclosure. For example, another configuration of the anchoring system for securing an outer wall member 12 to an inner wall member 14 is generally shown at 200 in
The veneer tie 210 of anchoring system 200 is generally analogous to the veneer tie 110 of anchoring system 100 and, thus, for ease of comprehension, where similar or analogous parts are used, reference numerals “100” units higher are employed. Accordingly, unless clearly stated otherwise, the above descriptions regarding veneer tie 110 also apply to veneer tie 210. The veneer tie 210 includes an attachment portion 212 and an insertion portion 214. In this embodiment, the attachment portion 212 is an inverted, U-shaped wire segment 216. The insertion portion 214 is generally perpendicular to the attachment portion 212. The insertion portion 214 includes first and second segments 222, 224 and first and second free end segments 226, 228. In this embodiment, each of the first and second segments 222, 224 includes a first longitudinal section 222A, 224A, extending from the attachment portion 212, an angled section 222B, 224B extending from the respective first longitudinal section and a second longitudinal section 222C, 224C extending from the respective angled section. The longitudinal sections 222A, 222C, 224A, 224C are generally parallel to the installation axis IA. The angled sections 222B, 224B generally extend away from one another at an angle to the installation axis IA. In this embodiment, the first and third recesses 232A, 232C are disposed on the angled sections 222B, 224B respectively and the second recess 232B is disposed on the second longitudinal section 224C of the second segment 224. Other configurations of the insertion portion 214 are within the scope of the present disclosure.

The veneer tie 310 includes an attachment portion 312 and an insertion portion 314. The attachment portion 312 is configured to be attached to the wall anchor 302 to secure the veneer tie 310 to the inner wall member 14. In the illustrated embodiment, the veneer tie 310 has a generally “L” shape. The attachment portion 312 includes a generally upstanding flange 316 that defines an elongate opening 317 sized and shaped to receive the wall anchor 302 there-through. When the attachment portion 312 is secured to the inner wall member 14, the upstanding flange 316 generally lays flat against the outer surface 18 of the inner wall member. Other configurations of the attachment portion 312 are within the scope of the present disclosure. For example, the attachment portion 312 could include slots configured to receive vertical flanges of a wall anchor or could include a channel-tee configured to mate with a vertical channel of a wall anchor (not shown).
The insertion portion 314 of the veneer tie 310 is configured for disposition in a bed joint 22. The insertion portion 314 is coupled to or formed as one piece of material with the attachment portion 312. The insertion portion 314 generally extends outward in a direction from the attachment portion 312. In the illustrated embodiment, the insertion portion 314 is generally perpendicular to the attachment portion 312. As shown in
The insertion portion 314 includes a plurality of holders 324 (broadly, two, three, four, five, etc. or more holders). In the illustrated embodiment, the insertion portion 314 includes six holders 324A-F, although more or fewer holders are within the scope of the present disclosure. Each holder 324 is configured to receive and hold the wall reinforcement 104. Specifically, each holder 324 is configured to grip one of the first or second reinforcement members 106, 107 of the wall reinforcement 104 to couple the wall reinforcement to the veneer tie 310.
The holders 324 permit the wall reinforcement 104 to be coupled to the veneer tie 310 at different locations (e.g., different longitudinal locations). Each holder 324 is configured to receive and hold the wall reinforcement at a location in the direction along the installation axis IA different than at least one other holder. This allows a builder to select which holder or holders 324 receive the wall reinforcement 104 to compensate for construction variances between the inner and outer wall members 14, 12 by enabling the wall reinforcement to be installed at different positions on the veneer tie 310. The holders 324 are generally spaced part from one another in a direction parallel to installation axis IA. Specifically, each holder 324 is spaced apart from at least one other holder in a direction parallel to installation axis IA. Preferably, the distance between the outer most holders 324A, 324F (e.g., the holders closest to the ends 318, 220, respectively) is less than a width of the masonry units 24 so that all of the holders can overly the masonry unit, if needed. Each holder 324 includes opposing first and second tabs 326, 328. The first and second tabs 326, 328 are spaced apart from one another and define a wall reinforcement space 330 there between for receiving the wall reinforcement 104 (specifically, a reinforcement member 106, 107 thereof). The tabs 326, 328 include one end attached to the flange 322 and a free end disposed generally above the flange. The free ends of the tabs 326, 328 oppose and face another and define a gap through which the wall reinforcement 104 can be inserted through to be positioned in the wall reinforcement space 330. In one embodiment, each holder 324 is configured to snap-fit with the wall reinforcement 104. Preferably, the mouth is narrower than the wall reinforcement 104, thereby requiring the wall reinforcement 104 to deflect and push the tabs 326, 328 away from each other and out of the way in order to enter the wall reinforcement space 330. The tabs 326, 328 are resiliently deflectable and return (e.g., snap back) toward their original positions once the wall reinforcement 104 has passed through the mouth. In the illustrated embodiment, the tabs 326, 328 are struck from the material of the flange 322 and bent upward.
In the illustrated embodiment, the holders 324 are arranged into a plurality of holder sets 332 (broadly, two or more holder sets). In the illustrated embodiment, there are three holder sets 332A-C, although more or fewer holder sets are within the scope of the present disclosure. Each holder set 332 is configured to receive and hold the wall reinforcement 104 at a location different than the other holder sets (broadly, two or more locations). The first holder set 332A receives and holds the wall reinforcement 104 at an outer or first location or position on the veneer tie 310 (
In operation, the wall anchor 302 is used to secure the veneer tie 310, via the attachment portion 312, to the inner wall member 14. The insertion portion 314 is in a substantially horizontal plane with the bed joint 22. The insertion portion 314 extends across the cavity 20 into the bed joint 22. The wall reinforcement 104 extends along the bed joint 22 and overlies the insertion portion 314. The wall reinforcement 104 is inserted into the holders 324 (e.g., holder sets 332) which position the wall reinforcement most centrally within the bed joint 22. The wall reinforcement 104 and insertion portion 314 are surrounded by (e.g., embedded within) the mortar and secured within the bed joint 22.
The veneer tie 310 of the anchoring system 300 is formed from a piece of material having a generally planar shape. In the illustrated embodiment, the veneer tie 310 comprises a unitary piece of material having a generally “L” shape. The material may be sheet metal or any other suitable material capable of providing a robust connection between the outer wall member 12 and the inner wall member 14. In one embodiment, the veneer tie 310 is stamped from a unitary piece of sheet metal and bent into shape. A blank can be cut from a piece of sheet metal and then bent, cut, stamped, struck, etc. into shape. For example, the tabs 326, 328 of each holder 324 may be struck out from the piece of sheet metal.
Components between anchoring systems 100, 200, 300 are generally interchangeable. For example, wall anchors 102 and 202 are interchangeable.
