tieKey: ICF Masonry Anchor
February 25th, 2010 | Lets Get Technical!, Product Announcement
Since we are talking about Carleton College from the last couple posts, I have to bring up the tieKey masonry anchor as that project used over 20,000 of them for the brick veneer.
Reward Wall Systems tieKey is the only patent-pending ICF masonry anchor in the market. It is an easy to install, cast-in-place, adjustable masonry tie anchor embedded into the concrete wall formed by the ICF. This product is designed to provide the strength and security required when installing brick or stone veneer finishes, and providing a strong resistance to negative and positive lateral loads.
Reward’s tieKey® is part one of a two-part system: Reward’s ICF masonry anchor and any standard wire tie(not provided). The masonry anchor is inserted through the ICF as the wall is constructed. The wire tie is installed by the mason contractor as the masonry facing is constructed. The tieKey® has been tested for tension and compression strength by an independent laboratory to verify its capacity to resist lateral loads. This innovative product is available in two materials, either hot-dipped galvanized or stainless steel.
Engineering Requirements
Ultimately the tieKey anchor must meet the design requirements for the project specific design loads and the building code requirements for spacing. The tieKey anchor is designed to resist the negative and positive lateral loads imposed by seismic and wind.
The tieKey anchor has been tested for strength by an independent laboratory — Structural Research Laboratory at the University of Nebraska — Lincoln’s Pieter Kiewit Institute. Testing has shown more than adequate strength to resist high seismic and wind lateral loads.
Building codes dictate a maximum horizontal and vertical spacing along with a maximum area of wall that a tieKey anchor must be located. To meet building code requirements and to work well with all Reward ICF product lines, we recommend placing the tieKey anchor every 16 inches vertically in the center of each course of ICF, and centered between the two plastic tie rods and every 24 inches on center horizontally.
This product is one of the ancillary items Reward provides to customers, to ensure a successfully built ICF building enclosure.
