A concrete form assembly has at least two opposed insulation panels. A plurality of vertical studs are formed on the outer face of each panel. The panels are connected by a plurality of bridges and retaining clips are disposed on the ends of each of the bridges against the studs on each panel. Concrete is received between the panels. Several embodiments of bridges and of retaining clips are disclosed. A concrete wall having at least one panel attached is disclosed. A method of forming the concrete wall is disclosed.

The present invention is directed to a concrete form assembly of panels which are spaced apart to form walls into which concrete is poured for construction purposes and to the wall formed thereby. More particularly, the present invention is directed to the panels and to means of assembling the panels to form a wall.
It is known that insulated polystyrene panels may be joined together to form walls which are interconnected with bridges so that two parallel walls are formed into which concrete may be poured for construction purposes.
The applicant is aware of the following patents which are directed to walls of structures which are formed from concrete and block and have cross supporting structure.
These and other objects of the present invention will become apparent from a reading of the following specification taken in conjunction with the enclosed drawings.
FIG. 1 is a front plan view of the present invention showing a panel with a plurality of studs and retainer clip means in some of the openings.
FIG. 2 is a cross-sectional view taken across the lines 2—2 of FIG. 1 further showing the loop bridges.
Referring now to FIGS. 1-3, an insulated panel 10 is substantially rectangular having a top 12, a bottom 14, a first side 16, an opposite second side 18, an inner face 20 and an outer face 22. The sides 16, 18, top 12 and bottom 14 have tongues and grooves formed therein as disclosed in U.S. Pat. No. 6,240,692 B1. In this manner, a plurality of panels 10 may be joined top and bottom and side to side to form a wall of desired dimensions. Preferably, each panel is 20 inches in height, 48 inches in length and 2½ inches in thickness. However, these dimensions may be changed as needed. Each panel is a molded plastic preferably formed from flame retardant expanded polystyrene.
A plurality of studs 24 are vertically disposed on the outer face 22 of each panel 10. The studs 24 are equidistantly spaced apart. The spacing may be 8 inches, 12 inches or 16 inches on center as commonly used in the construction industry or may be of any other desired spacing. Preferably, the stud is made of sheet metal of a desired thickness although the stud may be made of a rigid and sturdy plastic. Construction of metal is more economical because of the material cost and the manufacturing costs. Manufacturing costs for plastic include expensive molds, expensive molding equipment and high energy. Metal studs may be roll formed or extruded to a desired shape. The studs may be formed close to or immediately below the surface of the panel 10. It is preferred that each stud 24 have a length from the top 12 to the bottom 14 of the panel 10 to which it is attached.
Preferably, the studs 24 each have two outer columns 26 with a center column 28 therebetween. The center column 28 preferably is recessed with respect to the outer columns 26. The recess is formed within the outer face 22 of the panel. The recess may be in the shape of a triangle, rectangle, trapezoid, semi-circle, other arcuate shape or there may be a plurality of aligned depressions formed between the outer columns 26. A depressed center column is not essential.
