Abstract
An anchoring system for cavity walls is disclosed and includes a stud-type wall anchor and veneer tie. The stud-type anchor is comprised of high-strength, nonconductive thermally-isolating components that maintain the insulation R-values. The anchor has a driver head, dual-diameter barrel, a driven tip and multiple thermally-isolating seals. The multiple seals and the dual-diameter barrel of the anchor fill the anchor-receiving channel and stabilize the wall anchor. The wall anchor is clamped in place by the multiple seals. The anchor operates with various veneer ties.

An anchoring system for use in an insulated cavity wall having an inner wythe and an outer wythe with a cavity therebetween, the outer wythe formed from a plurality of successive courses with a bed joint between each two adjacent courses, the inner wythe having an exterior layer with rigid insulation disposed thereon, the insulation having an anchor-receiving channel therethrough extending from the exterior layer and opening onto the cavity, the anchoring system comprising, in combination:
- a wall anchor having an elongated body extending along a longitudinal axis from a driven end to a driving end, the wall anchor, in turn, comprising:
- a threaded portion at the driven end of the elongated body;
- a first shaft portion of a predetermined length contiguous with the threaded portion and extending therefrom toward the driving end, the first shaft portion having a substantially larger diameter and forming an insertion flange;
- a second shaft portion contiguous with the first shaft portion and extending therefrom toward the driving end, the second shaft portion having a substantially larger diameter and forming a vapor seal flange therebetween, the second shaft portion dimensioned with a diameter for a press fit relationship with the anchor-receiving channel;
- a driver portion at the driving end contiguous with the second shaft portion and forming an insulation flange therebetween;
- an insertion seal disposed on the wall anchor at the insertion flange;
- an insulation seal disposed on the wall anchor at the insulation flange, the insulation seal configured to seal the opening of the anchor-receiving channel;
- and,
- a veneer tie in an interlocking relationship with the wall anchor;
- whereby the insertion seal and the insulation seal have a press fit relationship with the anchor-receiving channel limiting the lateral displacement of the wall anchor thereby precluding pinpoint loading.
An anchoring system for use in an insulated cavity wall having an inner wythe and an outer wythe with a cavity therebetween, the outer wythe formed from a plurality of successive courses with a bed joint between each two adjacent courses, the inner wythe formed from a drywall backup wall mounted on metal studs or columns having an exterior layer with an air/vapor barrier and insulation disposed thereon, the anchoring system comprising, in combination:
- a wall anchor having an elongated body extending along a longitudinal axis from a driven end to a driving end, the wall anchor, in turn, comprising:
- a self-drilling threaded portion at the driven end of the elongated body;
- a first shaft portion of a predetermined length contiguous with the threaded portion and extending therefrom toward the driving end, the first shaft portion having a substantially larger diameter and forming an insertion flange;
- a second shaft portion contiguous with the first shaft portion and extending therefrom toward the driving end, the second shaft portion having a substantially larger diameter and forming a vapor seal flange therebetween;
- a driver portion at the driving end contiguous with the second shaft portion and forming an insulation flange therebetween, the driver portion configured, upon installation, to form a channel for the anchor in the insulation, the channel extending from the exterior layer and opening onto the cavity;
- a vapor seal disposed on the wall anchor at the vapor seal flange, the vapor seal and the second shaft portion at the vapor seal flange having a combined length along the longitudinal axis to be coextensive with the channel in the insulation, the vapor seal configured to seal the channel at the insertion point of the wall anchor through the air/vapor barrier;
- an insertion seal disposed on the wall anchor at the insertion flange;
- and, a veneer tie in an interlocking relationship with the wall anchor, the veneer tie having an insertion portion configured for embedment in the bed joint of the outer wythe;
- whereby the second shaft portion is driven into a press fit relationship with the channel limiting the lateral displacement thereof.
An anchoring system for use in an insulated cavity wall having an inner wythe and an outer wythe with a cavity therebetween, the outer wythe formed from a plurality of successive courses with a bed joint between each two adjacent courses, the inner wythe having an air/vapor barrier and insulation disposed thereon, the anchoring system comprising, in combination:
- a wall anchor having an elongated body extending along a longitudinal axis from a driven end to a driving end, the elongated body having a dual diameter with a first diameter and a second diameter, the wall anchor, in turn, comprising:
- a threaded portion at the driven end of the elongated body;
- a first shaft portion of the first diameter contiguous with the threaded portion and extending therefrom toward the driving end, the first shaft portion having a substantially larger diameter and forming an insertion flange;
- a second shaft of the second diameter portion contiguous with the first shaft portion and extending therefrom toward the driving end, forming a vapor seal flange between the first shaft portion and the second shaft portion;
- a driver portion at the driving end contiguous with the second shaft portion and forming an insulation flange therebetween;
- a vapor seal disposed at the vapor seal flange;
- an insertion seal disposed on the insertion flange;
- an insulation seal disposed on the insulation flange;
- and,
- a veneer tie in an interlocking relationship with the wall anchor, the veneer tie having an insertion portion configured for embedment in the bed joint of the outer wythe.
