    摘要： A prefabricated wall system for free-standing subdivision partitions, highway sound and visual barriers, privacy walls, or walls of a building having a plurality of prefabricated modular panels that are removably interconnected and installed. Each panel is essentially a factory-built sandwich having an expanded plastic foam core between two composite reinforcing wafers. Each wafer is comprised of an inner layer of fiberglass coated with an exterior layer of concrete reinforced with a grid of steel bars. The foam core has a pair of vertical cylindrical voids sized and spaced to mate with foundation columns pre-poured on site. The ends of each panel are reinforced with a steel sling lifting assembly embedded in concrete that includes removable eyebolts at the top edge whereby the panels can be attached to cables at each end for hoisting above the foundation columns and then lowering into place. A vertical groove or trough at each end of the panels receives a connector, such an expansion joint filler. Alternatively the panels can be formed with male tongues at one end and female grooves at the other for tongue-and-groove connection with adjacent panels. The foundation columns can support the panels above ground so that storm runoff waters pass freely thereunder.
