Pinning
and Re-Anchoring |
|
| Stitch-Tie
is a Stainless Steel (Type 304) pinning solution for re-anchoring existing
veneers to various sub-strates. The process eliminates that need to tear
down and replace existing facades, and preserve the beauty and historical
integrity of the existing building. Stitch-Tie pins are installed in pre-drilled
holes by use of a dry set tool and a rotary hammer. The percussion action
of the drill will create the driving forces necessary for the spiral shaped
tie to thread into the building material. Once installed, the helical shape
offers an in-plane flexible connector between wythes of material, while
maintaining a threaded connection to resist out of plane loading for both
tension and compression resistance. |

Stitch-Tie
does not draw walls together – therefore tension forces between wythes
are not present. They are installed in relatively small holes that are easily
patched and concealed. Various diameters and lengths are available for numerous
applications. Stitch-Tie can also be field trimmed using cutters for optimum
length requirements. |

cracked brick veneers by pointing a 4 mm x 40” long Stitch-Tie bar
across the distressed section. Bed the bar in Stitch-Tie grout, approximately
1” deep in the 1-1/2” (minimum) cut bed joint, and then finish
the process by pointing the last 1/2” with compatible mortar. Space
Stitch-Tie bars vertically at 6 course intervals along the length of crack,
above and below its ending. |

Anchor
Spacing |
|
|
Stitch-Tie
anchors are typically installed at one anchor per 2 square feet of veneer
area to be retrofitted. It is recommended that you refer to your local building
codes and standards for spacing condition requirements of wall ties and
anchors for appropriate compliance. |
