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. |

Repair
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. |

Each
construction site is unique and the appropriate use of this
product is the responsibility of the engineers, architects and
other professionals who are familiar with the specific requirements
of the project. The data reflects results of lab, field and
in-house tests and are provided as a guideline for the designer.
Site testing is encouraged for verification of load capacity. |
