The Heli-Tie is a stainless steel helical tie used to anchor building facades to structural members or to stabilize multiple wythe brick walls. The helical design allows the tie to be driven quickly and easily into a predrilled pilot hole or embedded into mortar joints in new construction to provide a mechanical connection between a masonry facade and its backup material or between multiple wythes of brick.
As it is driven, the fins of the tie undercut the masonry to provide an expansion free anchorage that will withstand tension and compression loads.
The Heli-Tie is installed using a proprietary setting tool that is used with an SDS Plus shank roto hammer to drive and countersink the tie.
The Heli-Tie performs in concrete and masonry as well as wood an steel studs.
Full range of sizes, 3/8 x 6" thru 3/8 x 12"
Installs quickly and easily. With the roto hammer in drill and hammer mode the tie installs faster than competitive products.
Provides an inconspicuous repair that preserves the appearance of the building. After installation, the tie is countersunk up to 1/2" below the surface, allowing the tie location to be patched.
Corrosion resistant stainless steel.
Larger core diameter provides higher torsional capacity resulting in less deflection due to "uncoiling" under load.
Fractionally sized anchor, no metric drill bits required.
Patented manufacturing process results in a more uniform helix along the entire tie allowing easier driving and better interlock with the substrate.
304 stainless steel ( 316 stainless steel available by special order, contact Sierra for details).
Drill pilot hole through the facade material and to the specified embedment depth + 1" in the backup material using appropriate drill bit. Drill should be in rotation only mode when drilling into soft masonry or into hollow backing material.
Position the Heli-Tie in the installation tool and insert the tie into the pilot hole.
With the SDS-Plus roto hammer in rotation and hammer mode, drive the tie until the installation tool shoulders up to the exterior surface of the masonry and the drive pin is fully extended. The installation tool will countersink the tie below the surface.Patch the hole in the facade using a color- appropriate material.
