Rubble stone anchoring system

摘要

Anchoring systems for use in cavity wall structures having an inner wythe and an outer wythe constructed of rubble stone are disclosed. The anchoring system employs an anchor fastened to or set within the inner wythe that extends into the cavity and connects to a J-hook. A vertically adjustable veneer tie enwraps the J-hook, limiting lateral movement and front-to-back displacement, and is set within the bed joint of the outer wythe. The anchoring system minimizes cavity size and provides stability for an uncoursed outer wythe equivalent to that of anchoring systems for standards coursed bed joints.

1. An anchoring system for use in a wall having an inner wythe and an outer wythe in a spaced apart relationship with a cavity therebetween, said outer wythe formed from a plurality of rubble stones having a bed joint between adjacent rubble stones, said rubble stones having an irregular surface, said anchoring system comprising:
a sheet metal wall anchor configured to be disposed on said inner wythe, said wall anchor, in turn, comprising:
a base portion having a planar body; anda planar free end portion contiguous with said base portion, said free end portion configured to extend into said cavity, said free end portion having a first receptor, wherein the first receptor comprises an aperture extending through the free end portion; a connection bar formed of wire having a fitting at one end thereof for interengaging said first receptor and an elongated body depending therefrom, and, upon interengagement with said first receptor said elongated body is disposed in said cavity, wherein the connection bar is configured for loose interengagement with the first receptor such that the connection bar is free of fixed connection to the anchor and is vertically movable with respect to the anchor; and, a veneer tie for disposition on said connection bar, said veneer tie in turn comprising:
an aperture at one end thereof dimensioned for limiting lateral movement and front-to-back displacement; andan insertion end portion configured for embedment in said bed joint of said outer wythe; whereby said veneer tie is limited to vertical alignment with said bed joint.
