A building component having first and second high density foam panels and improved bridging members for connecting the panels that extend between and may be molded into the panels. The bridging members include a pair of elongated end plates oriented in a top to bottom direction of the panels, a pair of substantially identical web members joining the end plates and being substantially symmetrically disposed above and below a central horizontal axis of the bridging member, and a pair of strip members oriented in the top to bottom direction of the panels intersecting the web members. The web members have a unique configuration that maximizes load bearing capacity with a minimum amount of material. The strip members may abut against and be substantially flush with respective inner surfaces of the foam panels to assist in positioning and forming the panels during molding. Seating areas for positioning horizontally and/or vertically disposed rebar in predetermined positions are also provided.

What is claimed is: 1. Apparatus for connecting opposing panels of an insulated concrete form comprising: a pair of elongated end plates; a pair of generally X-shaped structural members with a first one of said members forming an X-shape above a central horizontal axis and a second one of said members forming an X-shape below the central horizontal axis, said pair of structural members joining said end plates and being substantially symmetrically disposed above and below the central horizontal axis of the connecting apparatus, one of said X-shape structural members includes at least one lower leg having a different dimension than at least one lower leg of the other structural member, said structural members being configured to maximize load bearing capacity with a minimum amount of material; and at least one retaining member intersecting one of said structural members to assist in positioning the connecting apparatus relative to the panels and resisting external loads applied to the end plates. 2. The apparatus according to claim 1, wherein said at least one retaining member intersects said structural members on one side of a central vertical axis of the apparatus. 3. The apparatus according to claim 1, wherein said at least one retaining member comprises a ski-shaped strip member having curved ends. 4. The apparatus according to claim 3, wherein said curved ends of said ski-shaped strip member curve outwardly toward one of said end plates. 5. The apparatus according to claim 3, wherein said strip member is wider than said structural members in a direction substantially parallel to said end plate. 6. The apparatus according to claim 1, wherein said structural members include receptacles for positioning at least one of horizontally or vertically disposed rebar. 7. The apparatus according to claim 1, wherein at least one of said structural members has one of a generally X-shaped portion and a generally double-Y shaped portion between said end plates. 8. The apparatus according to claim 7, wherein said at least one retaining member comprises two retaining members intersecting said structural members on each side of a central vertical axis of the apparatus, and each of said structural members has one of a generally X-shaped portion and a generally Y-shaped portion between said retaining members. 9. The apparatus according to claim 1, wherein said end plates, said structural members and said at least one retaining member are formed integrally from a single piece of material. 10. The apparatus according to claim 1, further comprising legs defining V-shaped portions extending between said at least one retaining member and one of said end plates. 11. The apparatus according to claim 10, wherein said V-shaped portions define a plurality of triangular-shaped openings for passage of foam during the molding of the panels. 12. Apparatus for connecting opposing panels of an insulated concrete form comprising: a pair of elongated end plates; a pair of structural members joining said end plates and being substantially symmetrically disposed above and below a central horizontal axis of the connecting apparatus, said structural members being configured to maximize load bearing capacity with a minimum amount of material; and at least one retaining member intersecting one of said structural members to assist in positioning the connecting apparatus relative to the panels and resisting external forces applied to said endplates, wherein said at least one retaining member comprises a ski-shaped strip member having at least one radiused end curved outwardly toward one of said end plates. 13. The apparatus of claim 12, wherein said strip member is wider than said structural members in a direction substantially parallel to said end plates. 14. The apparatus of claim 12, wherein both ends of said at least one retaining member are radiused and curved outwardly toward one of said end plates. 15. Apparatus for connecting opposing panels of an insulating concrete form comprising: a pair of elongated end plates; a pair of structural members joining said end plates and being substantially symmetrically disposed above and below a central horizontal axis of the connecting apparatus, said structural members being configured to maximize load bearing capacity with a minimum amount of material; and at least one retaining member intersecting one of said structural members to assist in positioning the connecting apparatus relative to the panels, wherein said at least one retaining member comprises a ski-shaped strip member having curved ends and said curved ends curve outwardly toward one of said end plates. 16. The apparatus of claim 15, wherein said strip member is wider than said structural members in a direction substantially parallel to said end plates.
