Abstract
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.
