Abstract
A wall system employing channel-reinforced lightweight precast concrete wall panels. The precast wall panels include a concrete slab, a pair of spaced-apart elongated generally parallel metallic side channels, and a plurality of spaced-apart elongated generally parallel metallic attachment channels. The side channels and attachment channels are partially embedded in the slab and extend substantially perpendicular to one another. Each wall panel can be coupled to a support wall by extending self-tapping screws through metallic wall framing members and the attachment channels at locations where the framing members and attachment channels cross.
Claims12
A lightweight precast wall panel comprising:
- a concrete slab presenting side edges that define an outer perimeter of the slab;
- a pair of elongated spaced-apart first channels;
- and
- a plurality of elongated spaced-apart second channels,
- said first and second channels being partially embedded in the slab and extending substantially perpendicular to one another,
- said first and second channels being spaced inwardly from the outer perimeter of the slab,
- at least some of said second channels being disposed generally between the first channels,
- each of said channels including a substantially flat cross member and a pair of spaced-apart side members extending from the cross member,
- said slab presenting a substantially flat inside surface from which the channels project,
- said cross member being defined along a plane that is at least substantially parallel to the inside surface of the slab,
- said cross member being spaced from the inside surface of the slab a distance in the range of from about 0.5 to about 3 inches.
