Patent ID: 8713871

Claim:
A preformed wall panel having base and top ends and two vertical side edges for installation on a supporting surface, comprising: a) a wall portion having a width, height and thickness to provide structural rigidity and fitted on one side, a flange side, with a vertical flange form having an interior flange volume for forming a flange on the wall portion when filled with binder material wherein the improvement comprises: b) a footing form for providing a footing volume to be filled with binder material, the footing form having an upper wall-mounted edge portion extending along the side of the wall portion, the footing form being positioned above and near adjacent to the base end of the wall panel and extending across the width of the wall panel to the respective vertical side edges of the wall panel, the footing form further: i) extending laterally away from the wall portion on the flange side of the wall portion and having the upper wall-mounted edge portion embedded in or otherwise permanently attached to the wall portion so as to cause the footing form to remain permanently with the wall portion once the footing volume has been filled with binder material to thereby serve as reinforcing for the binder, and being: ii) positioned beneath, connected to and extending laterally from the flange form to provide the footing volume whereby the footing form can be filled with binder material that serves as a footing along the base end of the panel, iii) downwardly open but upwardly closed for covering and confining such binder material between the footing form, the flange side of the wall portion and the supporting surface when the wall panel is installed on such supporting surface, and iv) open at the ends of the footing form that are adjacent to the respective vertical side edges of the wall panel, and wherein the flange and footing volumes are interconnected to provide continuous, enclosed volumes that serve to contain binder material poured into the footing form through the vertical flange form, and wherein, when two such preformed wall panels are positioned next to each other along their vertical side edges, the adjacent openings at the ends of the enclosing footing form will permit a continuous, interconnected, covered, footing volume to extend between two adjacent wall panels.
