FORM TIE SLEEVES FOR COMPOSITE ACTION INSULATED CONCRETE SANDWICH WALLS

摘要

An elongate sleeve tie is used with casting form ties in the manufacture of composite wall structures. The casting form ties and sleeve ties act to secure one or more casting forms in a rigid position relative to an insulating layer positioned between the casting forms during the manufacture of composite wall structures. The casting form tie is received in a central recess of the elongate sleeve tie. Once the composite wall has been formed, the casting form ties may be pulled out of the wall, leaving the elongate sleeve ties in place. Removal of the casting form ties eliminates the thermal bridges that metal casting form ties would otherwise create. At least a portion of the sleeve tie is formed of a material having a high thermal resistance.
