Thermally Coated Wall Anchor and Anchoring Systems with In-Cavity Thermal Breaks for Cavity Walls

摘要

Thermally-isolating wall anchors and reinforcement devices and anchoring systems employing the same are disclosed for use in masonry cavity walls. A thermally-isolating coating is applied to the wall anchor, which is interconnected with a wire formative veneer tie. 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 wall anchors 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.

主权项

1. A thermally-isolating wire formative wall anchor and reinforcement device for use with an anchoring system in a cavity wall having an inner wythe and an outer wythe, the inner wythe 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 inner wythe and the outer wythe in a spaced apart relationship the one with the other forming a cavity therebetween, the anchor and reinforcement device comprising:
a wall reinforcement configured for embedment within the bed joint of the inner wythe, the wall reinforcement 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 wall anchor fusibly attached 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;a veneer tie receptor portion contiguous with each of the one or more leg portions set opposite the wall reinforcement, the veneer tie receptor portion configured to interengage a veneer tie; and,a thermally-isolating coating disposed on the veneer tie receptor portion, the coating being selected to have 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 wall anchor restricts thermal transfer between the veneer tie and the wall anchor and between the wall anchor and the veneer tie.
