Abstract
Wall system employing lightweight precast concrete wall panels. The precast wall panels include a concrete slab and a plurality of spaced-apart elongated generally parallel bent sheet metal channels that are partially embedded in the slab. Each wall panel can be coupled to a support wall by extending self-tapping screws through metallic wall framing members and the channels at locations where the framing members and channels cross.
