Abstract

A relatively thin flat panel of thermal insulating material is provided with an array of holes or apertures, each coaxially aligned or coextensive with a reinforcement bar emanating from a concrete slab forming an interior floor within a structure consistent with the design of a structural engineer of record. Rebar couplers (nipples) are arranged within each of the holes or apertures of the insulating panel having axial lengths greater than the thickness of the panel to extend beyond the panel on both sides thereof. The couplers are threaded both internally and externally. Nuts or threaded washers are threaded and tightened on both sides of each coupler to secure the coupler in place in relation to the panel. Alternatively, fiberglass rebars can be used extending through the insulating panel.

Claims

1. A thermal break for use in construction comprising a panel formed of insulation material having a thermal resistance and defining opposing spaced parallel major surfaces;

reinforcing bar sections extending in opposite directions from each of said major surfaces and having lengths suitable for being tied to a reinforcement grid of external reinforcement bars, each reinforcing bar section extending from one major surface being associated with a reinforcing bar section extending from the other opposing major surface for transmitting tension forces, associated reinforcing bar sections including thermal insulation means for providing thermal resistance between each two associated reinforcing bar sections, whereby a module is formed for providing thermal resistance both through said panel and through said reinforcing bar sections for reducing flow of heat through said reinforcing bar sections from one side of said module to the other.

2. A thermal break as defined in claim 1, wherein said panel comprises a foam insulation panel.

3. A thermal break as defined in claim 2, wherein said foam panel is made of closed cell foam.

4. A thermal break as defined in claim 2, wherein said foam panel is formed of polystyrene foam.

5. A thermal break as defined in claim 1, wherein said thermal insulation means comprises an insulating section of rod, and each pair of associated reinforcing bar sections on opposite sides of said panel are integrally formed with said section of rod.

6. A thermal break as defined in claim 5, wherein said reinforcing bar sections and section of rod form a continuous integral reinforcement bar extending through said panel.

7. A. thermal break as defined in claim 6 wherein said reinforcement bar is formed of fiberglass.

8. A thermal break as defined in claim 1, further comprising a protective sheet substantially covering said panel.

9. A thermal break as defined in claim 8, wherein said protective sheet is formed of metal sheets covering at least said major surfaces.

10. A thermal break as defined in claim 9, wherein said metal sheets are formed of electro-galvanized sheets.

11. A thermal break as defined in claim 10, wherein said sheets are 20 gage.

12. A thermal break as defined in claim 8, further comprising a protective coating fully covering and encapsulating said panel, protective sheet and at least portions of said reinforcing bar sections proximate to said panel.

13. A thermal break as defined in claim 12, wherein said protective coating is fire retardant.

14. A thermal break as defined in claim 1, wherein said panel is formed of epoxy resin.

15. A thermal break as defined in claim 14, wherein said epoxy resin incorporates woven fiberglass.

16. A thermal break as defined in claim 1, wherein said panel includes an insulating layer of air between said major surfaces.

17. A thermal break for use in construction comprising a panel formed of insulation material having a high thermal resistance and defining opposing spaced parallel major surfaces:

reinforcing bar sections extending in opposite directions from each of said major surfaces and having lengths suitable for being tied to a reinforcement grid of external reinforcement bars, each reinforcing bar section extending from one major surface being associated with a reinforcing bar section extending from the other opposing major surface for transmitting tension forces; and

thermal insulation means within said panel for providing thermal resistance between each two associated reinforcing bar sections, whereby a module is formed for enhancing thermal resistance both through said panel and through said reinforcing bar sections for reducing flow of heat from one side of said module to the other, wherein said associated reinforcing bar sections have threaded ends and further comprising a plurality of nipples extending through said panel each having opposing threaded ends for mating engagement with the threaded ends of said reinforcing bar sections.
