Thermally-isolated anchoring systems with split tail veneer tie for cavity walls

摘要

A high-strength thermally-isolating surface-mounted anchoring system for a cavity wall is disclosed. The thermally-isolated anchoring system is adaptable to various structures, including high-span applications, and for use with a split tail veneer tie. The anchoring system includes an anchor base and a stepped cylinder which sheaths the mounting hardware to limit insulation tearing and resultant loss of insulation integrity. The anchoring system is thermally-isolated through the use of multiple strategically placed compressible nonconductive seals or elements. Seals are also provided to preclude penetration of air, moisture, and water vapor into the wall structure.

主权项

1. A high-strength thermally-isolating anchoring system for use in a cavity wall, the cavity wall having a wallboard inner wythe and insulation thereon, anchor-receiving channels therethrough, and an outer wythe formed from a plurality of successive courses of masonry units, rubble stones or panels, the inner wythe and the outer wythe being arranged in a spaced apart relationship with respect to each other forming a cavity therebetween, the anchoring system comprising, in combination:
a wall anchor having a stepped cylinder portion and a base portion, the wall anchor being configured for surface-mounting in the inner wythe, the wall anchor further comprising: a stepped cylinder portion having steps thereof arrayed about a common longitudinal axis having one or more external diameters, the stepped cylinder portion containing a wallboard step and an insulation step, the stepped cylinder having a shaftway therethrough to sheath a fastener; and a base portion having a mounting surface adjacent the stepped cylinder portion, the mounting surface being configured to preclude penetration of air, moisture and water vapor through the inner wythe and is formed with one or more interconnection slots;
the fastener extending from the base portion and adapted for disposition in the shaftway of the stepped cylinder portion affixing the wall anchor to the inner wythe; a split tail veneer tie interconnected with the one or more interconnection slots and configured for interconnection with the outer wythe; and
multiple thermally-isolating seals including a wallboard seal, an insulation seal and a stepped cylinder seal, the wallboard seal being disposed within the stepped cylinder at a juncture of the wallboard step and the insulation step, the insulation seal being disposed at an exterior of the insulation step adjacent to the juncture of the insulation step and the base portion, and the stepped cylinder seal being disposed in an interior of the stepped cylinder about the fastener at the juncture of the stepped cylinder and the base portion.
