A pre-cast concrete building panel, adapted for use in even a load-bearing wall without additional framing, comprising a continuous peripheral metal channel frame, a concrete mass poured in situ in the frame, with the frame serving as the form, a slab of insulation embedded in the concrete but spaced at its edges from the metal frame, relatively heavy upper and lower shear bars welded to the frame and extending across the panel through the upper and lower edge portions of the concrete, and a lighter wire fabric reinforcement embedded in at least one face of the concrete mass. A plurality of short cantilever re-bars, welded to and projecting inwardly of the vertical sides of the frame, reinforce the vertical edges of the concrete mass. |
