CONCRETE INSERT FOR ATTACHING WALL PANELS TO BUILDING STUCTURES

摘要

Concrete inserts are disclosed which are preferably embedded in the rea r surface of a concrete wall panel and used to mount and support the wall pane l from a building frame. The insert preferably comprises a U-shaped metal housing defining a longitudinally extending channel, the housing comprising two side members in spaced, facing relation to one another and a bight portion betwee n the side members, the bight portion having a longitudinally extending slot therethrough. The insert is adapted to be embedded in the rear surface of the wall panel with the bight portion flush with the rear surface and the side members embedded in t he concrete of the panel. The side members are preferably of a trapezoidal shap e which provides the insert with high resistance to withdrawal from the concrete. The concrete insert preferably has a nut received in a concrete-free chamb er beneath the opening in the bight portion, a single piece of foam plastic preferably being used to retain the nut in position and prevent liquid concrete from entering the concrete-free chamber during casting of the wall panel.
