Abstract

Anchoring systems for use in cavity wall structures having an inner wythe constructed of interengaged composite panels and a veneer outer wythe are disclosed. The wall anchor is disposed within the juncture of the interengaged composite panels and fastened to the frame. The wall anchor maintains a strong interlock with the composite panels and backup wall, maintains insulation integrity and limits thermal transfer, without obstructing the juncture of the composite panels. The anchoring system interlocks with varied veneer ties, allowing vertical and horizontal adjustment for alignment with the bed joints. The anchoring system for composite panels provides an economical, high strength, low weight, insulated backup wall construction for interengagement with a veneer outer wythe.

Claims

1. An anchoring system for use in a wall having a backup wall and a veneer in a spaced apart relationship with a cavity therebetween, said backup wall formed from a plurality of interengaged composite panels having a juncture between adjacent panels, said panels mounted on a frame, said anchoring system comprising:

a Z-shaped wall anchor configured for disposition within said juncture of said adjacent panels, said wall anchor, in turn, comprising;

a base portion having a planar body,

a panel-housed portion attached to said base portion and adapted to be disposed in said backup wall, the panel housed portion having a free edge opposite a location where the panel housed portion is attached to the base portion, the panel housed portion being planar from the free edge toward the location of attachment to the base portion,

one or more free end portions attached to said base portion opposite the panel-housed portion and oriented at a non-zero angle with respect to the base portion and adapted to extend into said cavity, each of said one or more free end portions having a planar body, each of said one or more free end portions further comprising;

a receptor portion disposed therein and configured for receiving a veneer tie; and

,

a fastener configured for mounting said base portion of said wall anchor to said frame.

2. An anchoring system as described in claim 1, wherein said veneer is formed from a plurality of successive courses of bricks with a bed joint between adjacent courses, wherein said anchoring system further comprises:

a veneer tie having an interengaging end for disposition in said receptor portion and an insertion end configured for embedment in said bed joint of said veneer.

3. An anchoring system as described in claim 2, wherein said veneer tie further comprises:

front leg portions configured for insertion into said bed joint of said veneer;

side leg portions coextensive, perpendicular, and substantially co-planar with said front leg portions; and

,

a pair of pintle portions coextensive with said pair of side leg portions and upon installation configured to be vertically disposed for insertion through said receptor portion, said veneer tie being vertically adjustable to a substantially horizontal position.

4. An anchoring system as described in claim 2, wherein said veneer tie is a wire formative and further comprises:

a receiving end for threading through said receptor portion of each of said one or more free end portions;

an insertion end contiguous with and opposite said receiving end, said insertion end being swaged for interconnection with a reinforcement wire adapted to be disposed in said bed joint;

whereby, upon installation of said anchoring system with an interconnected reinforcement wire in said veneer, said system provides a high degree of seismic protection.

5. An anchoring system as described in claim 2, wherein said anchoring system further comprises:

a connection bar having a receiving end for disposition in said receptor portion and a connection end opposite said receiving end for disposition in said cavity; and

wherein

the veneer tie has an apertured end for disposition on said connection bar and an insertion end configured for embedment in said bed joint of said veneer;

whereby said veneer tie is horizontally disposed and adjustable for vertical alignment with said bed joint.

6. An anchoring system as described in claim 1, wherein said wall anchor is a metal stamping constructed of material selected from a group consisting of galvanized steel, hot dip galvanized steel, stainless steel, and bright basic steel.

7. An anchoring system as described in claim 1, wherein said frame is a metal column, and wherein said fastener comprises:

a bolt having a head; and

an insulative washer for mounting under said head of said bolt;

whereby said fastener is adapted to secure said anchor to said composite panel and said frame and minimizes thermal transfer between said frame and said anchoring system.

8. An anchoring system as described in claim 1, wherein said panel-housed portion is contiguous with said base portion and further comprises prongs disposed opposite said base portion, whereby upon insertion of said prongs into said composite panels said prongs are adapted to secure said wall anchor to said backup wall, providing a gauge for positioning said receptor portion, and minimizing thermal transfer.

9. An anchoring system as described in claim 1, wherein said panel-housed portion is contiguous with each of said one or more free end portions and said base portion.

10. An anchoring system as described in claim 1, wherein the wall anchor comprises a plurality of free end portions contiguous with said base portion and disposed opposite said panel-housed portion at spaced intervals, each free end portion being adapted to extend into said cavity and comprising a receptor portion disposed therein.

11. An anchoring system for use in a wall having a backup wall and a veneer in a spaced apart relationship with a cavity therebetween, said backup wall formed from a plurality of interengaged composite panels having a juncture between adjacent panels, said panels mounted on a frame, said anchoring system comprising:

a Z-shaped wall anchor configured for disposition within said juncture of said adjacent panels, said wall anchor, in turn, comprising;

a base portion having a planar body,

a panel-housed portion attached to and contiguous with said base portion and adapted to be disposed in said backup wall, the panel housed portion having a free edge opposite a location where the panel housed portion is attached to the base portion, the panel housed portion being planar from the free edge toward the location of attachment to the base portion, said panel-housed portion further comprising;

prongs disposed opposite said base portion and secured within said composite panel;

one or more free end portions attached to and contiguous with said base portion and oriented at a non-zero angle with respect to the base portion, each of said one or more free end portions disposed opposite said panel-housed portion, each of said one or more free end portions having a planar body and being adapted to extend into said cavity, each of said one or more free end portions further comprising;

a receptor portion disposed therein and configured for receiving a veneer tie; and

,

a fastener configured for mounting said base portion of said wall anchor to said frame.

12. An anchoring system as described in claim 11, wherein said veneer is formed from a plurality of successive courses of bricks with a bed joint between adjacent courses, wherein said anchoring system further comprises:

a veneer tie having an interengaging end for disposition in said receptor portion and an insertion end configured for embedment in said bed joint of said veneer.

13. An anchoring system as described in claim 11, wherein said wall anchor is a metal stamping constructed of material selected from a group consisting of galvanized steel, hot dip galvanized steel, stainless steel, and bright basic steel.

14. An anchoring system as described in claim 11, wherein said frame is a metal column, and wherein said fastener comprises:

a bolt having a head; and

an insulative washer for mounting under said head of said bolt;

whereby said fastener is adapted to secure said anchor to said composite panel and said frame and minimizes thermal transfer between said frame and said anchoring system.
