Abstract
A symmetrical load transfer device for use in insulated concrete wall panels. The symmetrical shape allows for forces induced in manufacturing, transportation, installation and nature to transfer through the device equally to both concrete wythes of the wall panel. The load transfer device is preferably made of a thermoplastic or thermoset resin matrix incorporating continuous filaments, such as glass rovings. The low thermal conductivity of the matrix of filaments and resins greatly reduce thermal bridging of the insulation layer while maintaining structural integrity of the wall panel.
