Abstract

A concrete panel system includes first, second, and third rectangular precast concrete panels, each defining a respective top edge, bottom edge, and first and second lateral edges. A first type connector is formed in the concrete material at least along the top edge of the first panel and along the first lateral edge of the first panel. A second type connector is formed in the concrete material at least along the second lateral edge of the second panel, and along the bottom edge of the third panel. The first type connector and the second type connector are configured to connect together, and a cavity is formed between the respective panel edges. This cavity extends along both the top edge of the first panel and the first lateral edge of the first panel to facilitate positioning reinforcing bar traversing a corner of the first or second panel.
