The
mechanical repair anchor has been used for over 25 years in the masonry
renovation marketplace. The Torque-Tie mechanical anchoring
system is an easy to use and cost effective method to re-connect existing
veneers to various substrates. The process eliminates the need to tear down
an existing veneer by providing a corrosion resistant tie assembly. The
components are manufactured of AISI Type 300 series austenitic stainless
and ASTM Type 360 brass. The combination provides for long-term durability
and structural stability for the design life of the structure.
The 5000 and 5100
Series System consists of brass expansion elements that are
situated in the veneer and backup segments of the wall system being rehabilitated.
They are torque activated which provides a method of inspection for both
the façade and backup connections. The two independent expanders
are connected via a stainless steel shaft and hardware.
The 5300
Series System utilizes the brass expander as a connection
means for the outer wythe. The backup has a lag thread self-tapping end,
for secure connection to timber or steel stud, on a stainless steel shaft.
The installation accuracy can be inspected via toque for both connectors
in the two wythes. The 5300
Series is available in either 1/2” or 3/8” diameter.
Once installed, the anchors resist veneer loading in both compression
and tension. The design of the system provides two independently activated
expanders that do not create tension between wythes. Basically, the Torque-Tie
system replicates a wall tie’s performance. That is, live loads
on the veneer are transferred to the backup thereby stiffening the veneer
which minimizes crack potential. Torque-Tie anchors are
typically installed at “T” joint or bed joint locations, concealed
with a mortar patch or sealant, and have no exposed hardware.
The Torque-Tie anchors are manufactured of applicable
ASTM materials. They are available in a variety of lengths, and can be
made to special lengths upon request.
