Abstract: A precast composite wall structure and method for forming the wall structure are disclosed. The method includes providing a casting bed defining a plurality of shapes corresponding to a three-dimensional outer surface of a wall structure, placing a first layer of uncured concrete to conform to the shapes defined by the lower surface, positioning a forming member in overlying relation above the frame, the forming member defining a plurality of rectangular-shaped channels therebetween, positioning a stud frame within the casting bed along the forming member, placing a second layer of uncured concrete within the casting bed to conform to the rectangular-shaped channels between the rectangular protrusions, and allowing the concrete to cure.

Abstract: A precast concrete panel and method for forming the panel are disclosed. A method of forming the panel to be used as a floor, wall, or roof structure includes positioning one or more forming members within a casting bed having a plurality of upright surfaces defining a generally rectangular interior area, the one or more forming members comprising an insulating material extending along a length dimension of the one or more forming members to define a plurality of rectangular-shaped channels in a parallel and spaced-apart relationship, placing uncured concrete within the casting bed and allowing the concrete to cover the one or more forming members and substantially fill the channels, and allowing the concrete to cure.

Abstract: A precast concrete wall structure and method for forming a wall structure are disclosed. A frame is positioned within a casting bed. The frame comprises first and second spaced apart metal tracks which are interconnected by a plurality of metal studs. The casting bed has a plurality of surfaces defining a generally rectangular interior area. A forming member is placed above the frame, the forming member comprising a layer of insulating material defining a plurality of integrally-formed rectangular protrusions extending in a parallel and spaced-apart relationship to one another to define a plurality of rectangular-shaped channels therebetween. Uncured concrete is placed within the casting bed and allowed to cure.
