Patent ·
OSTI ID:1998418
; ; ; ; ;

A stripping lifting insert is provided for precast insulated panels having an insulating material layer between opposing wythes, the insulating material layer, wythes, and precast insulated panel having respective widths. The stripping lifting insert includes an elongated connecting shaft having a shaft axis. First and second spaced apart wythe engagement members are connected to the connecting shaft in spaced apart relation to each other. Each wythe engagement member includes a hub and a plurality of three or more protrusions connected to and emanating from hub. Each of the protrusions extending radially outward from the shaft axis. The wythe engagement members have a height less than the width of the wythes, whereby each wythe engagement member can be completely embedded in a respective wythe of the precast insulated panel. A precast insulated panel and a method of making a precast insulated panel are also disclosed.
