Abstract

A structural panel for a building structure includes first and second stud members each including a neck. Openings and venturi bridges are formed in the neck. At least one flange is attached to the neck. A foam panel extends between the studs. The openings in the neck limit the heat transferred from the stud to the edge of the foam panel. The venturi bridges in the neck also limit the transfer of heat from the neck to the edge of the foam panel.

Claims

1. A structural panel for a building, comprising:

a plurality of I-beam stud members, each I-beam stud member being made of metal and having first and second flanges separated by a face which runs an entire length of each I-beam stud member, the first and second flanges having a thickness at least twice a thickness of the face, the first and second flanges being parallel to each other and perpendicular to the face, each I-beam stud member having a plurality of polygonal openings through the face separated only by venturi bridges, the polygonal openings having a first width in a first region of the polygonal opening and a second width in a second region of the polygonal opening, the first width being greater than the second width, each I-beam stud member further having a plurality of circular openings through the face adjacent to the second width of the polygonal openings, at least one of the venturi bridges having a raised area extending above the face, the plurality of polygonal openings blocking thermal conduction between the first and second flanges such that thermal conduction between the first and second flanges occurs only through the venturi bridges for the entire length of each I-beam stud member, the face having an area in the range of 1.33 to 5 times a cumulative area of the plurality of polygonal openings and in the range of 10 to 25 times a cumulative area of the venturi bridges to reduce thermal conduction between the first and second flanges; and

an insulating foam material disposed between the plurality of I-beam stud members, the insulating foam material being in contact with the face of the I-beam stud members.

2. The structural panel of claim 1, wherein the I-beam stud members and insulating foam material constitute a wall panel for the building.

3. The structural panel of claim 1, wherein the I-beam stud members and insulating foam material constitute a roof panel for the building.

4. The structural panel of claim 3, wherein the roof panel extends over a portion of the wall panel for providing a thermal seal between the roof and wall interconnection.

5. The structural panel of claim 3, wherein the roof panel includes:

a plurality of structural arms extending from the first flange of the I-beam stud member; and

a support member connected to the plurality of structural arms for hanging an interior portion of the roof panel.

6. The structural panel of claim 5, wherein the plurality of structural arms each includes an opening for reducing thermal conduction.

7. The structural panel of claim 1, further including brackets connected to a bottom portion of the structural panel for attaching to a foundation.

8. A structural panel for a building, comprising:

a plurality of I-beam stud members, each I-beam stud member being made of metal and having first and second flanges separated by a face, the first and second flanges having a thickness at least twice a thickness of the face, the first and second flanges being parallel to each other and perpendicular to the face, each I-beam stud member having a plurality of openings through the face separated by venturi bridges, each I-beam stud member further having a plurality of circular openings through the face, at least one of the venturi bridges having a raised area extending above the face, the plurality of openings blocking thermal conduction between the first and second flanges such that thermal conduction between the first and second flanges occurs through the venturi bridges, the face having an area in the range of 1.33 to 5 times a cumulative area of the plurality of openings and in the range of 10 to 25 times a cumulative area of the venturi bridges to reduce thermal conduction between the first and second flanges; and

an insulating foam material disposed between the plurality of I-beam stud members, the insulating foam material being in contact with the face of the I-beam stud members.

9. The structural panel of claim 8, wherein the I-beam stud members and insulating foam material constitute a wall panel for the building.

10. The structural panel of claim 8, wherein the I-beam stud members and insulating foam material constitute a roof panel for the building.

11. The structural panel of claim 10, wherein roof panel extends over a portion of the wall panel for providing a thermal seal between the roof and wall interconnection.

12. The structural panel of claim 10, wherein the roof panel includes:

a plurality of structural arms extending from the first flange of the I-beam stud member; and

a support member connected to the plurality of structural arms for hanging an interior portion of the roof panel.

13. A building, comprising:

a wall panel;

a roof panel extending over a portion of the wall panel for providing a thermal seal between the roof and wall interconnection, wherein the wall panel and roof panel each include,

(a) a plurality of I-beam stud members, each I-beam stud member being made of metal and having first and second flanges separated by a face, the first and second flanges being parallel to each other and perpendicular to the face, each I-beam stud member having a plurality of openings through the face separated by venturi bridges, the plurality of openings blocking thermal conduction between the first and second flanges such that thermal conduction between the first and second flanges occurs through the venturi bridges, the face having an area in the range of 1.33 to 5 times a cumulative area of the plurality of openings and in the range of 10 to 25 times a cumulative area of the venturi bridges to reduce thermal conduction between the first and second flanges, and

(b) an insulating foam material disposed between the plurality of I-beam stud members, the insulating foam material being in contact with the face of the I-beam stud members.

14. The structural panel of claim 13, wherein the face has a second plurality of openings adapted for passing conduit or wire between the plurality of I-beam stud members.

15. The structural panel of claim 13, wherein the roof panel includes:

a plurality of structural arms extending from the first flange of the I-beam stud member; and

a support member connected to the plurality of structural arms for hanging an interior portion of the roof panel.

16. The structural panel of claim 13, further including a bracket for connecting the roof panel to the wall panel.

17. A method of making a structural panel for a building, comprising:

providing a plurality of I-beam stud members, each I-beam stud member being made of metal and having first and second flanges separated by a face, the first and second flanges being parallel to each other and perpendicular to the face, each I-beam stud member having a plurality of openings through the face separated by venturi bridges, the plurality of openings blocking thermal conduction between the first and second flanges such that thermal conduction between the first and second flanges occurs through the venturi bridges, the face having an area in the range of 1.33 to 5 times a cumulative area of the plurality of openings and in the range of 10 to 25 times a cumulative area of the venturi bridges to reduce thermal conduction between the first and second flanges; and
