Cold formed, dual seal anchor and method of making
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.
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;
cold forming a large diameter barrel portion out of the length of metal;
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;
attaching a washer on the transition portion; and
abutting a washer 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.
2. The method of claim 1 , wherein at least one of the cold forming, the driver portion, the reduced diameter portion, the large diameter barrel portion and the transition portion 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 flange 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 , wherein the transition portion has a conical frustum shape.
7. The method of claim 1 , wherein the length of metal has a circular cross-sectional shape.
8. The method of claim 1 , further comprising cutting the length of metal from a metal coil.
9. The method of claim 1 , further comprising forming threads on the reduced diameter portion.
10. The method of claim 1 , wherein the transition portion tapers between the large diameter barrel portion and the reduced diameter barrel portion.
