Abstract
A high-strength ribbon loop anchor and cavity wall anchoring system employing the same is disclosed. The ribbon loop anchor is a wire formative construct that is cold-worked with the resultant body having substantially semicircular edges and flat surfaces therebetween. The edges are aligned to receive compressive forces transmitted from the facing wall. The ribbon loops hereof, when part of the anchoring system, interengage with the veneer tie and are dimensioned to preclude significant movement lateral with or normal to the inner wythe.
Claims17
A ribbon loop anchor and reinforcement device for use in a wall formed from a backup wall and a facing wall in a spaced apart relationship having a cavity therebetween, the backup wall being formed from a plurality of successive courses of masonry blocks with a mortar-filled bed joint of predetermined height between each two adjacent courses, the anchor and reinforcement device comprising:
- a wire formative wall reinforcement configured for embedment within the bed joint, the wire formative in turn, comprising;
- a pair of side wires disposed parallel to one another;
- one or more intermediate wires affixed to the interior sides of the side wires maintaining the parallelism thereof in a truss or ladder configuration;
- at least one wire formative wall anchor fusibly attached at one end thereof to the wall reinforcement, and, upon installation, extending into the cavity, the wall anchor comprising, in turn:
- one or more leg portions extending toward the cavity;
- one or more ribbon cavity portions contiguous with the one or more leg portions;
- and,
- a ribbon loop contiguous with each of the one or more ribbon cavity portions opposite the one or more leg portions, the ribbon loop being compressively reduced and configured to interengage a veneer tie for insertion within the facing wall.
A high-strength ribbon loop anchoring system for use in a cavity wall formed from a backup wall and a facing wall in a spaced apart relationship with a vertical surface of the backup wall forming one side of a cavity therebetween, the backup wall formed from a plurality of successive courses of masonry block with a bed joint of predetermined height between each two adjacent courses, the anchoring system comprising, in combination:
- a wall reinforcement with an upper surface in one plane and a lower surface in a plane substantially parallel thereto, the wall reinforcement adapted for mounting in the bed joint of the backup wall;
- at least one wire formative wall anchor fusibly attached at an attachment end thereof to the wall reinforcement, and, upon installation in the bed joint of the backup wall, extending between the plane of the upper surface and the plane of the lower surface to the vertical surface of the backup wall;
- the wall anchor, in turn, comprising:
- one or more extended leg portions for spanning the cavity, each extended leg portion having a free end contiguous therewith, opposite the attachment end and compressively reduced in thickness up to 75% of the original diameter thereof, the free end having a ribbon loop formed therefrom and extending to the attachment end, the ribbon loop being compressively reduced, the ribbon loop configured to interengage a veneer tie;
- and,
- a wire-formative veneer tie having an insertion end portion for disposition in the facing wall and an interengaging end portion for interengagement with the ribbon loop.
