Abstract

A light-weight, high-strength beam member for use in concrete form assemblies. A sheet material is roll-formed into a hollow beam having a trapezoidal transverse cross section. In assembly, a plurality of beam members are attached to a supporting metal concrete forming structure in a parallel, spaced-apart relation. Sheeting or decking is attached to the plurality of beam members by hand driven nails which penetrate a top section the beam members.

Claims

1. A structural framing member formed of a single piece of nail-penetrable sheet metal and having a trapezoidal transverse cross-section, said structural framing member comprising:

(a) a first planer section;

(b) a second planar section coextensive in length with said first planer section and of a width greater than said first planer section; and

(c) a pair of web sections of uniform width coextensive in length with said first planer section and said section planer section, and interconnecting said first planer section and said second planer section along corresponding adjacent edges thereof, said pair of web sections being connected to one another by said first planer section to form the structural framing member having the trapezoidal transverse cross-section.

2. The structural framing member of claim 1, wherein said web sections are provided with apertures of a sufficient size to allow hand access by a user to the interior of the structural framing member.

3. The structural framing member of claim 2, further comprising inwardly turned flanges bordering said apertures.

4. The structural framing member of claim 3, wherein said flanges and said apertures are circular.

5. The structural framing member of claim 1, wherein said first planar section and said second planar section are generally rectangular.

6. The structural framing member of claim 1, wherein the nail-penetrable sheet metal is high strength steel of a thickness between about 0.035 inches and about 0.10 inches.

7. The structural framing member of claim 6, wherein said first planar section is of a width between about 11/4 inches and 3 inches, said second planar section is of a width between said second planar section are separated by between about 3 inches and about 7 inches.

8. The structural framing member of claim 7, wherein said second planar section and said web sections define an internal angle of between about 70 degrees and about 80 degrees.

9. A frame assembly comprising:

(a) a structural framing member formed of a single piece of nail-penetrable sheet metal into a trapezoidal transverse cross-section, said structural framing member comprising;

(i) a first planer section;

(ii) a second planer section coextensive in length with said first planer section and of a width greater than said first planer section; and

(iii) a pair of web sections of uniform width coextensive in length to said first planer section and said second planer section and interconnecting said first planer section and said second planer section along corresponding adjacent edges thereof said pair of web sections being connected to one another by said first planer section, to form the structural framing member having said trapezoidal transverse cross-section;

(b) a sheeting material in supported engagement with said first planer section of said structural framing member; and

(c) fastening means penetrating said sheeting material and said first planer section of said structural framing member for maintaining said sheeting material in supported engagement with said first planer section of said structural framing member.

10. The framing assembly of claim 9, wherein said web sections are provided with apertures of a sufficient size to allow hand access by a user to the interior of said structural framing member.

11. The framing assembly of claim 10, further comprising inwardly turned flanges bordering said apertures.

12. The framing assembly of claim 11, wherein said flanges and said apertures are circular.

13. The framing assembly of claim 9, wherein said first planar section and said second planar section are generally rectangular.

14. The framing assembly of claim 9, wherein said nail-penetrable sheet metal is high strength steel of a thickness between about 0.035 inches and about 0.10 inches.

15. The framing assembly of claim 14, wherein said first planar section is of a width between about 11/4 inches and 3 inches, said second planar section is of a width between about 3 inches and 6 inches, and said first planar section and said second planar section are separated by between about 3 inches and about 7 inches.

16. The framing assembly of claim 15, wherein said second planar section and said web sections define an internal angle of about 70 degrees and about 80 degrees.
