PT Wall Ties

Basic Use & Types

PT wall ties are specifically designed for use in tilt-up sandwich wall or precast insulated panels. The ties provide a fast, efficient, cost effective method for casting a concrete sandwich wall panel.

Application Recommendations

PT wall ties are available for wall panels with insulation thicknesses ranging between 1.5″ and 4.5″. This provides ample R-value for buildings with ambient temperatures.

Performance

With sandwich wall panels, since lifting inserts are located in the interior structural layer of concrete, PT ties are designed only to support the fascia wythe during lifting. A typical 3-inch concrete fascia wythe weighs 37.5 lbs./ft2 and suction force between the casting surface and the fascia wythe is approximately 25 lbs./ft2.

Installation

PT ties are specifically designed for fast, accurate installation. With a nail profile, the ties can be installed directly through the insulation on a 16” on center pattern. After casting the reinforced exterior concrete wythe, the PT ties are inserted through the insulation into the fresh concrete. Construction of the structural concrete wythe continues in a manner similar to an un-insulated wall panel. Once the PT ties are in place, rebar, embed and lifting inserts are all set in place on top of the insulation. The concrete is then placed. With a compressive strength of 25psi, the insulation provides damage resistance from foot traffic and other job site abuse.

Availability

PT ties are manufactured by Concrete Insulation Systems (CIS), Ames, IA, and are available world-wide.

IF Wall Ties

Basic Use & Types

IF wall ties are specifically designed for use in tilt-up sandwich wall or precast insulated panels. The ties provide a fast, efficient, cost effective method for securing insulation to the interior side of a concrete wall panel.

Application Recommendations

IF wall ties are available for wall panels with insulation thicknesses ranging between 1.5” and 4.5”. This provides ample R-value for buildings with ambient temperatures where the insulation will be covered by appropriate fire protection.

Performance

IF ties are designed to secure the insulation to the wall and are supplied with a 1.5” diameter head to ensure security.

Installation

IF ties are specifically designed for fast, accurate installation. With a nail profile, the ties can be installed directly through the insulation on a 24” on center pattern. After casting the reinforced concrete wall panel, the IF ties are inserted through the insulation into the fresh concrete. Once the concrete has cured, the panel can be erected and finished with proper interior fire protection.

Availability

IF ties are manufactured by Concrete Insulation Systems (CIS), Ames, IA, and are available world-wide.

Liability

It is the sole responsibility of the contractor to install IF ties. CIS makes no warranty of merchantability and no warranty of fitness for any particular purpose, nor does it make any other warranty expressed or implied.
