Abstract

An insulated, substantially rectangular building block is disclosed. The block contains two spaced, outer supportive parts which are interlockably connected with each other and which extend along the length of the block; and a curvilinear inner insulating material is present in the space between the supportive parts. Each of the outer supportive parts has a configuration which differs from that of the other such part. The insulating material is wedge-shaped, and it fits into a space between said supportive parts which is defined by walls which extend inwardly from the top of the building block to its bottom.

Claims

1. An insulated building block of substantially rectangular shape comprised of a first spaced outer supportive part, a second spaced outer supportive part, curvilinear means for laterally interlockably connecting said first spaced outer supportive part and said second space outer supportive part, and a substantially curvilinear, integral inner insulating portion, wherein:

(a) each of said first spaced outer supportive part and said second spaced outer supportive part extends along the length of said building block, is comprised of an inner surface defining a side of the space between said parts, and has a configuration which differs from the configuration of the other of said spaced outer supportive parts;

(b) said space between said first and second spaced outer supportive parts is substantially curvilinear in cross section as viewed from the top of said building block;

(c) said space between said first and second spaced outer supportive parts is wedge-shaped and is defined by walls which extend inwardly from the top of said building block to the bottom of said building block;

(d) said insulating portion is positioned within an substantially fills the space between said first spaced outer supportive part and said second spaced outer supportive part, thereby forming said susbstantially rectangular building block;

(e) said building block is comprised of two opposite planar sidewalls, two opposite planar ends, a planar top, and a planar bottom;

(f) each of said planar sidewalls is parallel to the other of said planar sidewalls, each of said planar ends, is parallel to the other of said planar ends, and said planar top is parallel to said planar bottom;

(g) said insulating portion is substantially centered between and extends beyond each of said two planar ends;

and

(h) said insulating portion extends beyond at least one of said planar top surface and said planar bottom surface of said building block.

2. The insulating block as recited in claim 1, wherein said inner insulating material consists essentaily of at least one foam material.

3. The insulating block as recited in claim 2, wherein said inner insurating material has a density of from about 0.5 to about 4.0 pounds per cubic foot.

4. The insulating block as recited in claim 3, wherein said inner insulating material has a conductivity of from about 1.0 to about 0.35 British Thermal Units per inch hour per square foot of surface area per degree Fahrenheit.

5. The insulating block recited in claim 3, wherein said inner insulating material has a density of from about 1.0 to about 3.0 pounds per cubic foot.

6. The insulating block as recited in claim 5, wherein said inner insulating material has a tensile strength of from 27 to about 125 pounds per square inch.

7. The insulating block as recited in claim 6, wherein said inner insulating material has a compressive strength of from about 11 to about 92 pounds per square inch.

8. The insulating block as recited in claim 7, whrein said inner insulating material has a tensile strength of from about 42 to aobut 80 pounds per square inch.

9. The insulating block as recited in claim 8, wherein said inner insulating material has a flexural strength of from about 25 to about 125 pounds per square inch.

10. The insulating block as recited in claim 9, wherein said inner insulating material has a shear strength of about 25 to about 175 pounds per square inch.

11. The insulating block as recited in claim 10, wherein said inner insulating material has a melting point no lower than abut 140 degrees Fahrenheit.

12. The insulating block as recited in claim 11, wherein said inner insulating material has an R value of at least about 3.5 R per inch.

13. The insulating block as recited in claim 1, wherein each of said first outer supportive part and said second outer supportive part consist essentially of concrete or other aggregates commonly used in building blocks.

14. The insulating block as recited in claim 13, wherein each of said first outer supportive part and said second outer supportive part comprises at least one internal section so shaped as to enable a portion said supportive part to project within the confines of the other of said supportive part.

15. The insulating block as recited in claim 14, wherein each of said internal sections extends from the top of said building block to the bottom of said building block.

16. The insulating block as recited in claim 15, wherein each of said internal sections extends divergently from the top of said building block to the bottom of said building block.

17. The insulating block as recited in claim 16, wherein said inner insulating portion extends beyond said planar top surface of said building block.

18. The insulating block as recited in claim 16, wherein said inner insulating portion extends beyond said planar bottom surface of said building block.

19. The insulating block as recited in claim 16, wherein said inner insulating portion extends beyond both said planar top surface and said planar bottom surface of said building block.

20. The insulating block as recited in claim 17, wherein said inner insulating material has a density of from about 1.0 to about 2.0 pounds per cubic foot.

21. The insulating block as recited in claim 20, wherein said inner insulating material has a tensile strength of from about 42 to about 80 pounds per square inch.

22. The insulating block as recited in claim 21, wherein said inner insulating material has a compressive strength of from about 20 to about 53 pounds per square inch.

23. The insulating block as recited in claim 21, wherein said inner insulating material has an R value of at least about 3.5 R per inch.
