Concrete insert for attaching wall panels to building structures
First Claim
1. A concrete insert, comprising:
- an elongate bight portion having an upper surface and two longitudinal sides, said bight portion being adapted for connection to a fastener means; and
two generally planar side members, each having an inner face and an outer face, with said inner faces of said two side members being in spaced, facing relationship to one another, each of said side members extending downwardly from a respective one of said longitudinal sides of said bight portion,said side members being connected to one another only through said bight portion so that said side members and said bight portion together define a U-shaped, longitudinally extending channel having an open bottom and open ends,wherein each of said side members is wedge-shaped, having two longitudinally spaced, diverging end surfaces extending between said inner and outer faces and extending downwardly from the bight portion, the two end surfaces of each said side member diverging from one another with increasing distance from said bight portion.

Abstract
Concrete inserts are disclosed which are preferably embedded in the rear surface of a concrete wall panel and used to mount and support the wall panel 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 between 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 the concrete of the panel. The side members are preferably of a trapezoidal shape which provides the insert with high resistance to withdrawal from the concrete. The concrete insert preferably has a nut received in a concrete-free chamber 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.
