Abstract
An attachment for attaching a precast concrete wall panel to a building in a manner which permits vertical movement of that wall panel relative to building structural elements. In one embodiment, the attachment includes inserts embedded in the wall panel near the top and bottom edges of the upright wall panel, a tongue element connecting the top inserts to a building beam, or the like, and a clamp attached to the bottom inserts to connect those inserts to a building foundation. The inserts have slots defined therein in which portions of the tongue and clamp are located to permit the wall panel and building to move vertically with respect to each other.
