CHANNEL-REINFORCED LIGHTWEIGHT PRECAST CONCRETE WALL PANEL SYSTE M

摘要

Wall system employing channel-reinforced 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. The channels may be configured to include spaced-apart parallel side channels and perpendicularly extending intermediate attachment channels, and may individually include embedded openings. Each of the channels is cut and formed from a single piece of flat sheet metal.
