US 6,668,505 B1 · High-span anchors and reinforcements for masonry walls

Abstract

High-span and high-strength anchors and reinforcement devices for cavity walls combined with interlocking veneer ties are described which utilize reinforcing wire and wire formatives to form facing anchors, truss or ladder reinforcements, and wall anchors providing wire-to-wire connections therebetween. These combine wire formatives which are selectively and compressively reduced in height by cold-working. The masonry anchor have eye wires accommodating the threading thereinto of a wire facing anchor or wall tie with either a pintle inserted through the eye or the open end of the wall tie. The wall tie is then positioned so that the insertion end is embedded in the facing wall. The masonry anchor is embedded in a bed joint of the interior wythe. For high-strength applications, specific wire formatives are used which employ materials that benefit from the cold-working of the metal alloys to meet the unusual requirements demanded.

Dependent claims

A high-span anchor and reinforcement device 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, said cavity in excess of four inches, said backup wall formed from a plurality of successive courses of masonry block with a bed joint of predetermined height between each two adjacent courses, said high-span anchor and reinforcement device comprising, in combination:

a wall reinforcement with an upper surface in one plane and a lower surface in a plane substantially parallel thereto, said wall reinforcement adapted for mounting in said bed joint of said backup wall;
at least one wall anchor fusibly attached at an attachment end thereof to said wall reinforcement, and, upon installation in said bed joint of said backup wall, extending between said plane of said upper surface and said plane of said lower surface from an attachment end thereof to the vertical surface of said backup wall;
said wall anchor, in turn, comprising:
an extended leg portion for spanning said cavity said extended leg portion having at least one compressively reduced portion;
and,
a free end contiguous therewith, said free end opposite said attachment end and adapted to be disposed in said cavity, said free end adapted for interengageing with a veneer tie for said facing wall.

a wall reinforcement with an upper surface in one plane and a lower surface in a plane substantially parallel thereto, said wall reinforcement fabricated from wire and is adapted for mounting in said bed joint of said backup wall;
at least one wall anchor electric-resistance welded attached at an attachment end thereof to said wall reinforcement, and, upon installation, in said bed joint of said backup wall, extending between said plane of said upper surface and said plane of said lower surface from an attachment end thereof to said vertical surface of said backup wall, said wall anchor being a wire formative and said attachment end compressively reduced in height to be equal or less than the height of said wall reinforcement.
