Abstract
An insulated structural wall panel includes a monolithic concrete shell poured to conform to a structural reinforcing grid embedded in the shell with insulation panels fixed within the grid spaces. The layers of concrete which sandwich the insulation panels are rigidly tied together by use of tie rods extending through the insulation panel. This monolithic construction results in a lightweight panel with superior structural qualities, the concrete, the reinforcing grid and the insulation panels having been blended together into one homogeneous member. The panel may incorporate extraneous assemblies including doors, windows, vents, pipes, electrical junction boxes and the like. The reinforcing grid may also include various adaptive devices for suitable attachment of the concrete wall panel to concrete footings, floor slabs, roof members, temporary supports and the like.
