Abstract: Adjacent concrete wall panels are connected at the vertical joint by a shear connector structure that includes a metal connector angle embedded in a corner portion of one of the panels, and one or more threaded nuts or studs are welded to a flange of the angle. A metal shear connector plate has a hole for each threaded nut or stud and elongated holes or slots for the other concrete panel. After the panels are erected and positioned, the connector plate is bolted to the studs and self-tapping concrete anchor screws are inserted into the slots and threaded into holes formed in the other panel. The studs are formed by machinery weld studs to form a bore with threads at the welded end of each stud.

Abstract: A cast concrete wall panel is secured to a concrete foundation by an anchor system which includes a steel base plate embedded adjacent the bottom surface of the wall panel and welded to a tapered channel projecting upwardly adjacent the inner surface of the wall panel to define a cavity. Reinforcing bars have bottom ends welded to the base plate and project upwardly into the concrete wall panel, and a hole is formed in the base plate at the bottom of the cavity. The hole receives a self-tapping concrete anchor bolt which is driven into a hole drilled within the foundation at an acute angle less than twelve degrees and preferably about six degrees from vertical. The channel has a removable cap to prevent concrete from entering the cavity during casting of the wall panel and to provide a decorative inside cover for the cavity after installing the anchor bolt.
