Typically, masonry facades are intended to resist wind loads. In lieu of tear-down or replacement, an existing masonry or terra cotta facade can be fortified by the addition of mechanical ties or anchors. The Grip-Tie anchors provide additional facade stability, which may be needed to fulfill a myriad of requirements. The Grip-Tie selection process evolves by evaluating the type of anchors one can use to satisfy the repair (compatibility) and strengthening criteria. Also, one cannot ignore the means and methods of installation which can also influence the remedial anchor choice.Post-installed Grip-Tie repair anchors are available to accomplish the task. When dealing with a repair situation, the as-built material quality and current building conditions are often unknown. It is therefore not uncommon that installation criteria and performance qualification be obtained via field tests in order to confirm design assumptions. The Grip-Tie mechanical repair anchors consist of a dual expansion anchor for a mechanical connection that grips the backup and veneer which is then bridged with an anchor rod. The Grip-Tie anchor creates formidable gripping strength to the base material to which it is attached. The anchor does not draw walls together, thereby eliminating additional tension stresses between wythes of material. The backup material can be concrete, metal stud, wood stud, CMU (hollow or grouted), structural steel, or brick. The veneer can be brick, stone, or precast. The Grip-Tie anchor assembly is manufactured from corrosion-resistant materials which will contribute to the facade?s long-term durability and design life. The Grip-Tie anchorage system has been designed to accommodate easy installation via hand tools or power tools. Combining the strength, generous spacing, and affordable installation technique, the Grip-Tie mechanical repair anchor product line is a value-reward choice for facade re-anchoring.
INSTALLATION
A.Select proper anchor length by field verification.
B.Drill proper pilot hole size per anchor type and blow out drill fines.
C.Using appropriate setting tool and adapters, tighten back-up anchor to recommended torque range, then tighten facade portion to the recommended torque range.
D.Conceal anchor with specified grout or caulk
