Abstract

A modular seamless corner component for providing a corner to a structure without having to compromise between structural integrity and energy efficiency. The continuous insulation and structure of the modular seamless corner component provide for a stronger corner because there are no seams to magnify stress and provide for a high energy efficiency because there is no thermal bridging.

Claims (39)

1. A substantially L-shaped modular seamless corner component for providing a corner to a structure, comprising:

an outer sheath, an inner sheath, a first strap, a second strap, and an insulation;

wherein the inner sheath, the insulation, and the outer sheath each comprise a top edge, a bottom edge, and two outside edges, wherein each of the inner sheath, the insulation, and the outer sheath is substantially L-shaped, comprising a bend defining a seamless corner;

wherein the seamless corner of the inner sheath is nested within the seamless corner of the insulation, and the seamless corner of the insulation is nested within the seamless corner of the outer sheath;

wherein the inner sheath is attached to the insulation and the insulation is attached to the outer sheath such that the top edges of the inner sheath, the insulation, and the outer sheath are substantially flat and coplanar;

wherein the substantially L-shaped insulation is continuous between the inner sheath and the outer sheath;

wherein the entirety of the first strap is parallel to a first portion of the inner sheath and is positioned completely outside of the insulation; and

wherein the entirety of the second strap is parallel to a second portion of the inner sheath and is positioned completely outside of the insulation.

2. The substantially L-shaped modular seamless corner component of claim 1 , wherein the first strap includes a first flat side and a second flat side, wherein the first flat side of the first strap is parallel to the second flat side of the first strap.

3. The substantially L-shaped modular seamless corner component of claim 1 , wherein the second strap includes a first flat side and a second flat side, wherein the first flat side of the second strap is parallel to the second flat side of the second strap.

4. The substantially L-shaped modular seamless corner component of claim 1 , wherein the outer sheath extends below the bottom edges of the inner sheath and the insulation, wherein the bottom edges of the inner sheath and the insulation and the portion of the outer sheath which extends below the bottom edges of the inner sheath and the insulation define a lip.

5. The substantially L-shaped modular seamless corner component of claim 4 , wherein the portion of the outer sheath which extends below the bottom edges of the inner sheath and the insulation is continuous with the remainder of the outer sheath.

6. The substantially L-shaped modular seamless corner component of claim 1 , wherein the top edge of the insulation is directly covered by at least one embedded top plate positioned completely parallel to the top edge of the insulation.

7. The substantially L-shaped modular seamless corner component of claim 6 , wherein the substantially L-shaped modular seamless corner component is attached to two sidewalls.

8. The substantially L-shaped modular seamless corner component of claim 7 , wherein each of the two sidewalls is adjacent to an outside edge of the insulation, and wherein each of two secondary top plates extends over one of the two sidewalls such that each of the two secondary top plates covers a top of at least one of the two sidewalls.

9. The substantially L-shaped modular seamless corner component of claim 7 , wherein each of the two sidewalls includes a top plate and a bottom plate, wherein the top plate and the bottom plate are horizontal beams.

10. The substantially L-shaped modular seamless corner component of claim 1 , wherein the insulation comprises a foam, wherein the foam is injected between the inner sheath and the outer sheath, and wherein the foam adheres to the inner sheath and the outer sheath as the foam cures.

11. The substantially L-shaped modular seamless corner component of claim 10 , wherein the foam adheres to the inner sheath and the outer sheath with a bonding strength of at least 50 pounds per square inch.

12. The substantially L-shaped modular seamless corner component of claim 1 , wherein the substantially L-shaped modular seamless corner component does not include a vertical stud or any other type of stud.

13. A substantially L-shaped modular seamless corner component for providing a corner to a structure, comprising:

an outer sheath, an inner sheath, a first strap, a second strap, and an insulation;

wherein the inner sheath, the insulation, and the outer sheath each comprise a top edge, a bottom edge, and two outside edges;

wherein the insulation is positioned between the inner sheath and the outer sheath;

wherein the inner sheath is attached to the insulation and the insulation is attached to the outer sheath such that the top edges of the inner sheath, the insulation, and the outer sheath are substantially flat and coplanar;

wherein the insulation is continuous between the inner sheath and the outer sheath;

wherein the entirety of the first strap is parallel to a first portion of the inner sheath and is positioned completely outside of the insulation; and

wherein the entirety of the second strap is parallel to a second portion of the inner sheath and is positioned completely outside of the insulation.

14. The substantially L-shaped modular seamless corner component of claim 13 , wherein the outer sheath extends below the bottom edges of the inner sheath and the insulation, wherein the bottom edges of the inner sheath and the insulation and the portion of the outer sheath which extends below the bottom edges of the inner sheath and the insulation define a lip.

15. The substantially L-shaped modular seamless corner component of claim 13 , wherein the top edge of the insulation is directly covered by at least one embedded top plate positioned completely parallel to the top edge of the insulation.

16. A substantially L-shaped modular seamless corner component for providing a corner to a structure, comprising:

an outer sheath, an inner sheath, an insulation, a first strap, and a second strap,

wherein the inner sheath, the insulation, and the outer sheath each comprise a top edge, a bottom edge, and two outside edges;

wherein the insulation is positioned between the inner sheath and the outer sheath;

wherein the inner sheath is attached to the insulation and the insulation is attached to the outer sheath such that the top edges of the inner sheath, the insulation, and the outer sheath are substantially flat and coplanar;

wherein the insulation is continuous between the inner sheath and the outer sheath;

wherein the first strap is parallel to a first portion of the inner sheath and is completely positioned outside of the insulation, and wherein the second strap is parallel to a second portion of the inner sheath and is positioned completely outside of the insulation; and

wherein the outer sheath extends below the bottom edges of the inner sheath and the insulation, wherein the bottom edges of the inner sheath and the insulation and the portion of the outer sheath which extends below the bottom edges of the inner sheath and the insulation define a lip.

17. The substantially L-shaped modular seamless corner component of claim 16 , wherein the portion of the outer sheath which extends below the bottom edges of the inner sheath and the insulation is continuous with the remainder of the outer sheath.

18. The substantially L-shaped modular seamless corner component of claim 16 , wherein the top edge of the insulation is directly covered by at least one embedded top plate positioned completely parallel to the top edge of the insulation.
