US 9,038,350 B2 · One-piece dovetail veneer tie and wall anchoring system with in-cavity thermal breaks

Abstract

A dovetail anchoring system for cavity walls is disclosed and includes a sheetmetal dovetail anchor and one-piece sheetmetal dovetail veneer tie. The anchoring system is used in conjunction with building structures that have a masonry outer wythe anchored to a poured masonry inner wythe. A thermally-isolating coating is optionally applied to the high-strength veneer tie, which is interconnected with the wall anchor. The thermally-isolating coating is selected from a distinct grouping of materials, that are applied using a specific variety of methods, in one or more layers and cured and cross-linked to provide high-strength adhesion. The thermally-coated veneer ties provide an in-cavity thermal break that severs the thermal threads running throughout the cavity wall structure, reducing the U- and K-values of the anchoring system by thermally-isolating the metal components.

Dependent claims

A dovetail anchoring system for the interconnection of a masonry inner wythe and an outer wythe formed from a plurality of successive courses of masonry block with a bed joint, having a predetermined height, between each two adjacent courses, the inner wythe and the outer wythe in a spaced apart relationship the one with the other forming a cavity therebetween, the anchoring system comprising:

a dovetail wall anchor configured to be secured within the inner wythe and constructed from a sheetmetal body having two major faces being the mounting surface and the outer surface, the wall anchor, in turn, comprising:
a dovetail slot formed from the outer surface and extending the length of the outer surface;
and,
a sheetmetal veneer tie comprising:
an insertion portion having a first end configured for securement within the outer wythe bed joint and a second end contiguous with the first end;
and,
an interconnecting portion contiguous with the second end and opposite the first end, the interconnecting portion configured to be adjustably mounted within the dovetail slot;
and,
a thermally-isolating coating disposed only on the insertion portion, the coating having low thermal conductivity and transmissivity, the coating forming a thermal break in the cavity;
wherein upon installation within the anchoring system in the cavity wall, the veneer tie restricts thermal transfer between the veneer tie and the wall anchor and between the wall anchor and the veneer tie.

7 more elements

A unitary sheet metal veneer tie for use in a cavity wall to connect to a wall anchor to join an inner wythe and an outer wythe of the cavity wall, the veneer tie comprising:

an insertion portion having a first end configured for securement within a bed joint of the outer wythe of the cavity wall and a second end contiguous with the first end, the first end of the insertion portion forming a notch configured to receive a reinforcement wire, the notch comprising a seat formed by bending a portion of the insertion portion out of plane, the seat having a first portion bent downward out of plane from the first end of the insertion portion and a second portion bent upward from the first portion, the seat being configured to receive the reinforcement wire the notch further comprising a first securement tab struck from the insertion portion, the first securement tab being positioned adjacent the seat and configured to retain the reinforcement wire in the seat and a second securement tab struck from the insertion portion, the second securement tab being positioned adjacent the seat opposite the first securement tab, such that the seat is positioned between the first and second securement tabs, the first and second securement tabs being configured to receive and retain the reinforcement wire, the first and second securement tabs being configured to be positioned on opposite sides of a longitudinal axis of the reinforcement wire;
and
an interconnecting portion contiguous with the second end of the insertion portion, the interconnecting portion having a dovetail shape and being configured for mounting within a slot of the wall anchor.
