A lifting insert for a concrete sandwich panel is disclosed. The lifting insert includes a fiberglass rod and two end sleeves secured to two opposite ends of the fiberglass rod. The two end sleeves create confinement of fibers of the fiberglass rod to improve stress resistance of the fiberglass rod. The two end sleeves are also separated by a predetermined distance apart from each other to prevent/reduce thermal bridging. The lifting insert further includes two anchoring members secured to the two end sleeves for anchoring the fiberglass rod within the concrete sandwich panel.

Thermally non-conductive lifting insert for insulated concrete sandwich panels

The present disclosure is directed to a concrete sandwich panel. The sandwich panel may comprise a first reinforced concrete panel; a second reinforced concrete panel; an insulating panel sandwiched between the first reinforced concrete panel and the second reinforced concrete panel; a tie comprising a generally triangle wave-shaped pattern having a period defined by peaks spaced at a regular interval and a peak-to-peak amplitude greater than the thickness of the insulating panel; wherein the insulating panel has a plurality of generally linear slots defined at the regular interval of the tie for receiving the tie such that opposing ends of the tie terminate adjacent to the insulating panel, and the plurality of generally linear slots are filled utilizing an insulating material upon insertion of the tie to reduce thermal bridging; and wherein the peaks of the tie mechanically join the first and second reinforced concrete panels to the insulating panel.
