Abstract:
1. A reinforced composite system for constructing insulated concrete structures comprising: panels having inside and outside surfaces, top, bottom and end edges, said panels placed horizontally in an opposing and parallel, spaced-apart relationship, panels having an interlocking means at the top and bottom edge of each panel; said panels comprising, said panels having tapered edges, the outside face of each panel being tapered starting from each edge of the panel extending away from the panel edges toward the middle of each panel; at least two vertical studs embedded in each panel extending the full height of the panels, said studs spaced longitudinally and parallel from each other, said studs adhered within foam plastic core, the exterior of the panels being marked at each stud location allowing studs to be located visually; said studs comprising, at least one horizontal stiffener embedded in each panel between inside and outside surfaces of foam core and parallel to inside and outside surfaces of foam core, said horizontal stiffeners located equal distances from top and bottom edges of panels, said horizontal stiffeners adhered within foam plastic core; said interlocking means comprising, a tongue extending from and parallel to the top edge of each panel, and a complementary groove recessed into and parallel to the bottom edge of each panel said tongue and groove comprising complimentary preformed units adhered to the foam plastic core, the groove unit of each panel having appendages protruding into the grove, the spacing of the appendages corresponding with the locations of embedded studs, and the tongue unit of each panel having slots that compliment said appendages, such that when said panels are stacked the appendages in the grooves engage the slots in the tongues forcing studs from adjacent panels into a vertical alignment; a plurality of spreaders at each stud location, extending between opposing panels and slidably engaging the studs in opposing panels, thereby creating a form with a cavity between the inside surfaces of the panels for receiving fluid concrete; said spreaders comprising,
