L-shaped sheetmetal anchor with tubular leg and anchoring assembly

Abstract

An L-shaped sheetmetal anchor with tubular leg and an anchoring assembly employing the same are disclosed. The assembly is adaptable to varied anchoring structures and for use with interlocking veneer ties and reinforcement wires to provide a high-strength surface mounted anchoring system for cavity walls. The stepped cylinders sheath the mounting hardware to limit insulation tearing and resultant loss of insulation integrity. The assembly is thermally-isolated through the use of a series of strategically placed compressible nonconductive fittings. The assemblies are vertically or horizontally surface mounted on the inner wythe.
