Abstract

A cold formed anchor for use in an insulated cavity wall includes a unitary body formed with a driver portion and having large and small diameter portions. The driver portion may be formed with structure for connecting a veneer tie to the anchor. A method of making the cold formed anchor includes cold forming a driver portion and a reduced diameter portion from a blank.

First claim

What is claimed is:

1 . A method of making an anchor for use in an insulated cavity wall, the method comprising:
cold forming a driver portion of the anchor out of a length of metal at a distal end of the length of metal, the driver portion configured to be engaged to drive the anchor into an inner wythe of the insulated cavity wall; cold forming a reduced diameter portion of the length of metal at a proximal end of the length of metal, the proximal end opposite the distal end.

2 . The method of claim 1 , wherein the cold forming includes one or more of stamping, squeezing, shearing, drawing, punching and bending.

3 . The method of claim 1 , further comprising cold forming a first flange adjacent to the driver portion.

4 . The method of claim 3 , further comprising cold forming an aperture in the driver portion configured to receive a veneer tie.

5 . The method of claim 4 , further comprising abutting a seal against a distal face of the first flange, the seal configured to engage a portion of the inner wythe and form a fluid tight seal therewith.

6 . The method of claim 1 , further comprising attaching a washer on the length of metal generally at the intersection of the reduced diameter portion of the length of metal and the remainder of the length of metal.

7 . The method of claim 1 , further comprising cold forming a large diameter barrel portion out of the length of metal.

8 . The method of claim 7 , further comprising cold forming a transition portion out of the length of metal, the transition portion extending between and interconnecting the large diameter barrel portion and the reduced diameter barrel portion.

9 . The method of claim 8 , further comprising attaching a washer on the transition portion.

10 . The method of claim 9 , further comprising abutting a seal against a distal face of the washer, the seal configured to engage a portion of the inner wythe and form a fluid tight seal therewith.

11 . The method of claim 8 , wherein the transition portion has a conical frustum shape.

12 . The method of claim 1 , wherein the length of metal has a circular cross-sectional shape.

13 . The method of claim 1 , further comprising cutting the length of metal from a metal coil.

14 . The method of claim 1 , further comprising forming threads on the reduced diameter portion.

15 . A cold formed anchor for use in an insulated cavity wall, the anchor comprising:
a unitary body formed with a driver portion configured to be engaged to drive the anchor into an inner wythe of the insulated cavity wall, a large diameter barrel portion extending from the driver portion, a small diameter barrel portion configured to be driven into the inner wythe of the insulated cavity wall and a transition portion between and interconnecting the large diameter barrel portion and the small diameter barrel portion.

16 . The cold formed anchor of claim 15 , wherein the transition portion has a conical frustum shape.

17 . The cold formed anchor of claim 15 , wherein the unitary body further comprises a first flange adjacent to the driver portion and configured to engage an exterior surface of the inner wythe to form a fluid tight seal therewith.

18 . The cold formed anchor of claim 17 , further comprising a second flange extending radially outward from the transition portion and configured to engage a portion of the inner wythe to form a fluid tight seal therewith.

19 . The cold formed anchor of claim 18 , further comprising first and second seals, the first seal abutting the first flange and configured engage the exterior surf ace of the inner wythe to form the fluid tight seal, the second seal abutting the second flange and configured to engage the portion of the inner wythe to form the fluid tight seal.

20 . The cold formed anchor of claim 15 , wherein the unitary body comprises an aperture in the driver portion sized and shaped for receiving a portion of a veneer tie to connect the veneer tie to the unitary body.
