Abstract
A seismic construction system is disclosed having in combination: a masonry anchor, a wall tie, and a facing anchor. A reinforcing wire is disposed longitudinally in the inner masonry wythe and has attached spaced pairs of transverse wire portions. Each transverse wire portion extends into the cavity and terminates in an eye wire having an eye disposed vertically in the cavity and lying in a plane normal to the masonry wythe surface. The open end of the wall tie is threaded through a pair of eye wires of the masonry anchor, which eye wire portion extends into the cavity between the inner masonry wythe and the outer facing wythe. The masonry anchor is adapted to be embedded within the inner masonry wythe; and, after threading through the eye wires, the open end of the wall tie, within the outer facing wythe. The facing anchor includes a clip member which is constructed to accommodate the open end of the wall tie member and also a reinforcing wire disposed longitudinally in the facing wythe. Upon the closed end of the wall tie being captive in the eye wires of the masonry anchor and the open end of the wall tie and the clip of the facing anchor being embedded in the outer facing wythe, a seismic construct is formed with nominal endplay along the x- and z-axes and limited movement along the y-axis.

Description
Background of the Invention
1. Field of the Invention
This invention relates to a improved seismic construction system for use in conjunction with wall systems employing an inner wythe and an outer wythe. More particularly, to construction techniques for embedding a continuous wire in the mortar joints of both wythes and having a positive interconnection therebetween.
2. Information Disclosure Statement
In the past, investigations relating to the effects of earthquakes upon building structures demonstrated the advantages of having a continuous wire embedded in the mortar joint of anchored veneer walls. These investigations were referenced in the inventor's prior patent, namely U.S. Pat. No. 4,875,319. The referenced investigations resulted in the incorporation of a requirement for continuous wire reinforcement in the Uniform Building Code provisions covering seismic zone construction. The code requires that this wire is to be secured to the tie anchor which is fastened to the support structure. The use of a continuous wire in masonry veneer walls has been found to have additional benefits in providing protection against problems arising from thermal expansion and contraction and improving the uniformity of the distribution of the lateral forces in a structure.
The following patents are believed to be relevant and are disclosed as being known to the inventor hereof:
It is noted that these devices are generally descriptive of wire-to-wire anchors and wall ties and have various cooperative functional relationships with straight wire runs embedded in the interior and/or exterior wythe. Several of the prior art items are of the pintle and eyelet/loop variety without positive restriction on escape by vertical displacement.

Discloses a veneer wall anchor system having in the interior wythe a truss-type anchor, similar to Hala et al. '226, supra, but with horizontal sheetmetal extensions. The extensions are interlocked with bent wire pintie-type wall ties that are embedded within the exterior wythe.
U.S. Pat. No. 4,879,319--R. Hobmann--Issued Oct. 24, 1989
Discloses a seismic constructuion system for anchoring a facing veneer to wallboard/metal stud construction with a pronged sheetmetal anchor. Wall tie is distinguished over that of Schwalberg '990 and is clipped onto a straight wire run.
None of the above provide the seismic construction system for an inner masonry wythe and an outer facing wythe having a positive interconnection as described hereinbelow.
Summary
In general terms, the invention disclosed hereby includes a seismic construction system for use in the construction of wall structures having an inner masonry wythe and an outer facing wythe. The wythes are in a spaced apart relationship and form a cavity therebetween. In the disclosed system, a unique combination of a masonry anchor, a wall tie member, and a facing anchor is provided. The invention contemplates that the primary components of the system are reinforcing wire and wire-to-wire connections thereof.
In the best mode of practicing the invention, the masonry anchor has a truss portion with eye wire extensions welded thereto. The eye wires extend into the cavity between the wythes and accommodate the threading there into of one end of the wire wall ties. The masonry anchor is embdedded in a bed joint of the interior wythe. The facing anchor has a straight wire run and seismic clips mounted therealong to receive the other end of wire wall tie. The facing anchor is embedded in a bed joint of the exterior wythe. Because the eye wires have sealed eyelets or loops and the open ends of the wall ties are sealed in the joints of the exterior wythes, a positive interengagement results.

Description of the Preferred Embodiment
Referring now to FIGS. 1 to 3, the first embodiment of a seismic construction system of this invention is shown and is referred to generally by the numeral 10. In this embodiment, a wall structure 12 is shown having an interior wythe 14 of masonry blocks 16 and an exterior wythe 18 of facing brick 20. The interior wythe 14 of masonry blocks 16 is also referred to herein as an inner masonry wythe and, similarly the exterior wythe 18 of facing brick 20 is also referred to herein as an outer facing wythe. The Between the interior wythe 14 and the exterior wythe 18, a cavity 22 is formed. In the first embodiment, successive bed joints 24 and 26 are formed between courses of blocks 16 and the joints are substantially planar and horizontally disposed. Also, successive bed joints 28 and 30 are formed between courses of bricks 20 and the joints are substantially planar and horizontally disposed. Selected bed joint 24 and bed joint 28 are constructed to align, that is to be substantially coplanar, the one with the other. For purposes of discussion, the exterior surface 32 of the interior wythe 14 contains a horizontal line or x-axis 34 and an intersecting vertical line or y-axis 36. A horizontal line or z-axis 38 also passes through the coordinate origin formed by the intersecting x- and y-axes. In the discussion which follows, it will be seen that the various anchor structures are constructed to restrict movement interfacially--wythe vs. wythe--along the z-axis and, in this embodiment, along the y-axis. The system 10 includes a masonry anchor 40 constructed for embedment in bed joint 24, a facing anchor 42 constructed for embedment in bed joint 28 and an interconnecting wall tie number 44.
The masonry anchor 40 is shown in FIG. 1 as being emplaced on a course of blocks 16 in preparation for embedment in the mortar of bed joint 24. In the best mode of practicing the invention, a truss or reinforcement wire portion or first reinforcement wire portion 46 is constructed of a wire formative with two parallel continuous straight wire members 48 and 50 spaced so as, upon installation, to each be centered along the outer walls of the masonry blocks 16. An intermediate wire body or wire 52 is interposed therebetween and connects wire members 48 and 50 forming chord-like portions of the truss 46. At intervals along the truss 46, spaced pairs of transverse wire members 54 are attached thereto and are attached to each other by a rear leg 56 therebetween. These pairs of wire members 54 extend into the cavity 22. Inasmuch as the reinforcement portion 46 are emplaced in a direction along the wythe in an x-axis direction and are considered longitudinal, the wire members 54 of the masonryanchor 40 are in a direction across the wythe in a z-axis direction and are considered transverse. As will become clear by the description which follows, the spacing therebetween is constructed to limit the x-axis movement of the construct. Each transverse wire member 54 has at the end opposite the attachment end an eye wire portion 58 formed continuous therewith. A sheetmetal loop is an alternative construction in lieu of eye wires shown in the best mode; however, the wire formative has been found to be structurally superior. Upon installation, the eye 60 of eye wire portion 58 is constructed to be within a substantially vertical plane normal to exterior surface 32. The eye 60 is dimensioned to accept a wire tie therethrough and is thus slightly larger than the diameter of the tie. This relationship minimizes the y- and z-axis movement of the construct. For positive engagement, the eye 60 of eye wire portion 58 is sealed forming a closed loop.
The wall tie 44 is generally rectangular in shape and is dimensioned to be accommodated by a pair of eye wires 58 previously described. The wall tie 44 has a rear leg portion 62, two parallel side leg portions 64, and a base portion formed from two parallel front leg portions 66 and 68. To facilitate installation, the front leg portions 66 and 68 are spaced apart by the diameter of the wire member 54. The longitudinal axes of leg portions 62, 64, 66 and 68 are substantially coplanar. The side leg portions 64 are structured to function cooperatively with the spacing of transverse wire members 54 to limit the x-axis movement of the construct.
The facing anchor 42 is constructed from a straight wire member 70 and a clip member 72. The clip member 72 is an adaptation of the clip member described in U.S. Pat. 4,875,319, supra, and, like the predecessor, is of unitary construction. The clip member 72 includes a base portion 74 and a plurality of substantially parallel projections 76, 78, 80, 82 and 84 defining a plurality of channels 86, 88, 90, and 92. The spacing between projections is proportioned in a manner such that the two innermost channels accept the front leg portions 66 and 68 of the wall tie 44. The spacing forming the two outermost channels are dimensioned such that one or more wire members 70 of preselected diameters may be selectively inserted in the appropriate channel. The bottom portion 94 of the clip member 72 has a plurality of parallel grooves 96. These grooves facilitate the bonding of the clip member 72 to the mortar in the bed joints upon bricks 20. During the construction of the exterior wythe 18, the mortar also fills the channels of clip member 72 thereby bonding together the clip, the reinforcing wire and the wall tie member.
The description which follows is of a second embodiment of the seismic construction system. For ease of comprehension, where similar parts are used reference designators "100" units higher are employed. Thus, the clip member 172 of the second embodiment is analogous to the clip member 72 of the first embodiment. Referring now to FIGS. 4 to 6, the second embodiment of a seismic construction system of this invention is shown and is referred to generally by the numeral 110. As in the first embodiment, a wall structure 112 is shown having an interior wythe 114 of masonry blocks 116 and an exterior wythe 118 of facing brick 120. Between the interior wythe 114 and the exterior wythe 118, a cavity 122 is formed. Successive bed joints 124 and 126 are formed between courses of blocks 116 and the joints are substantially planar and horizontally disposed. Also, successive bed joints 128 and 130 are formed between courses of bricks 120 and the joints are substantially planar and horizontally disposed. Selected bed joint 124 and bed joint 128 are constructed to align, that is to be substantially coplanar, the one with the other. For purposes of discussion, the exterior surface 132 of the interior wythe 114 contains a horizontal line or x-axis 134 and an intersecting vertical line or y-axis 136. A horizontal line or z-axis 138 also passes through the coordinate origin formed by the intersecting x- and y-axes. The system 110 includes a masonry anchor 140 constructed for embedment in bed joint 124, a facing anchor 142 constructed for embedment in bed joint 128 and an interconnecting wall tie number 144.
The masonry anchor 140 is shown in FIG. 4 as being emplaced on a course of blocks 116 in preparation for embedment in the mortar of bed joint 124. In the best mode, a ladder- or truss-type reinforcement wire portion 146 is constructed of a wire formative with two parallel continuous straight wire members 148 and 150 spaced so as, upon installation, to each be centered along the outer walls of the masonry blocks 116. An intermediate wire body or a plurality of wires 152 are interposed therebetween and connects wire members 148 and 150 forming chord-like portions of the truss 146. At intervals along the truss 146, spaced pairs of transverse wire members 154 are attached thereto and are attached to each other by a rear leg 156 therebetween. These pairs of wire members 154 extend into the cavity 122. The spacing therebetween is constructed to limit the x-axis movement of the construct. Each transverse wire member 154 has at the end opposite the attachment end an eye wire portion 158 formed continuous therewith. Upon installation, the eye 160 of eye wire portion 158 is constructed to be within a substantially vertical plane normal to exterior surface 132. The eye 160 is elongated vertically in both directions to accept a wire tie therethrough from an unaligned bed joint and is slightly larger horizontally than the diameter of the tie. This dimensional relationship minimizes the z-axis movement of the construct. For positive engagement, the eye 160 of eye wire portion 158 is sealed forming a closed loop.
The wall tie 144 is generally rectangular in shape and is dimensioned to be accommodated by a pair of eye wires 158 previously described. When rectangular, the wall tie 144 has a rear leg portion 162, two parallel side leg portions 164, and two parallel front leg portions 166 and 168. To facilitate installation, the front leg portions 166 and 168 are spaced apart by the diameter of the wire member 154. The longitudinal axes of leg portions 162, 164,166 and 168 are substantially coplanar. The side leg portions 164 are structured to function cooperatively with the spacing of transverse wire members 154 to limit the x-axis movement of the construct.
The facing anchor 142 is constructed from a straight wire member 170 and a clip member 172. The clip member 172 is an adaptation of the clip member described in U.S. Pat. No. 4,875,319, supra, and, like the predecessor, is of unitary construction. The clip member 172 includes a base portion 174 and a plurality of substantially parallel projections 176, 178, 180, 182 and 184 defining a plurality of channels 186, 188, 190, and 192. The spacing between projections is proportioned in a manner such that the two innermost channels accept the front leg portions 166 and 168 of the wall tie 144. The spacing forming the two outermost channels are dimensioned such that straight wire member 170 of two preselected diameters may be selectively inserted in the appropriate channel. The bottom portion 194 of the clip member 172 has a plurality of parallel grooves 196. These grooves facilitate the bonding of the clip member 172 to the mortar in the bed joints upon bricks 120. During the construction of the exterior wythe 118, the mortar also fills the channels of clip member 172 thereby bonding together the clip, the reinforcing wire and the wall tie member.
Because many varying and different embodiments may be made within the scope of the inventive concept herein taught, and because many modifications may be made in the embodiments herein detailed in accordance with the descriptive requirement of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
