Description
BACKGROUND OF THE INVENTION
(i) Field of the Invention This invention relates to a building construction and, more particular, relates to a metal truss, metal components thereof, and to light weight framing structures constructed of said metal truss.
(ii) Description of the Related Art Open-web floor joists and roof rafters having wooden upper and lower wooden chords joined at equispaced intervals by U-shaped metal diagonals are known.
The truss construction has the advantage over solid wooden joists and rafters of permitting utilities such as plumbing, electrical wiring and ventilation ductwork to freely pass through open spaces in the trusses, while using up to 30% less material.
Light-weight structural framing systems comprised of solid metal channel and I-beam studs and top and bottom horizontal tracks and bridging channels joined by sheet metal angle brackets and gussets using sheet metal screws or by tack welds are also known.
The webs of the channel and I-beam joists are closed, necessitating the costly drilling or cutting of the webs by skilled workmen to allow utilities to pass through.
It is an object of the of the present invention therefore to provide a relatively inexpensive, light-weight, metal framing structure using a novel truss construction for floor joists, roof rafters and wall studs.
It is another object of the present invention to provide a building system having structural integrity for winds up to hurricane force and for severe earthquakes.
Another object of the invention is the provision of a building system which can be erected by local workmen after a brief training program.
~mar~~ of the Invention In its broad aspect, the metal truss of the invention for use as wall studs, floor joists and roof rafters comprises a pair of parallel, spaced-apart elongated metal tubes, preferably having a rectangular cross-section, having a plurality of diagonal members equispaced along said pair of tubes for interconnecting the tubes, said diagonal members being arranged in V-shaped pairs with a diagonal member of each pair being attachable on opposite sides of the elongated metal tubes, and connector means for joining the diagonal members to the elongated metal tubes. The diagonal members comprise elongated plates having flanged sides and enlarged end plates at each end thereof to facilitate assembly of the truss, the enlarged ends preferably being enlarged and oblique to the elongated plate.
The metal truss additionally comprises thermal break pads of a heat insulating material such as rubber, rubberized plastic or plastic between the diagonal members and the elongated metal tubes. A thermal break material can be disposed on the exterior wall faces of the trusses, such as on the outside faces of wall studs and rafters. The elongated metal tubes are formed from 18 to 26 gauge galvanized steel and the diagonal members are formed of 16 to 18 gauge galvanized steel, and the connector means are self tapping galvanized steel screws.

Description of the Preferred Embodiments The metal truss of the invention, as shown in the drawings, comprises metal floor joist trusses, metal wall stud trusses, and metal roof rafter trusses which can be factory assembled or transported to a building site for assembly. Exterior wall stud trusses and floor joist trusses are typified in Figures 1 and 2. Wall stud truss 10 consists of formed, rolled or extruded parallel metal chord tubes 12, 14 joined by a plurality of equispaced diagonal members 16 on each side thereof. Each diagonal member 16 preferably has enlarged oblique end plates 18 formed integral therewith at an angle to the long axis of the diagonal member to correspond to the long axis of the chord tubes whereby each diagonal member can be secured to the chord tubes at the desired diagonal angle to facilitate assembly and to maintain correct parallel spacing of tubes 12, 14.
End plates 18 preferably have two or three holes 19 formed therein for receiving and starting self tapping metal screws for screwing into chord tubes 12, 14 to secure the diagonal members 16 to the chord tubes. Plastic or rubberized plastic thermal insulator sheets or pads 17 about one-quarter inch thick are placed between diagonal members 16 and chord tubes 12, 14.
The chord tubes and diagonal members preferably are formed from galvanized steel, the exterior wall components, floor joists and roof trusses formed of zinc-coated light steel and interior wall studs formed for example of 26 gauge galvanized steel.
The elongated metal tubes preferably are formed of 18 to 26 gauge galvanized steel and the diagonal members of 16 or 18 gauge galvanized steel.
Figure 1 also illustrates a conventional roof truss assembly 20 preferably fabricated from metal components and seated on the upper end 22 of wall stud 10. Roof truss 20 has chord tubes 24 interconnected by screws 21 with insulator pads 23 for a thermal break.
It will be understood that roof rafter trusses similar to wall stud trusses 10 or floor joist trusses 30, to be described, can be employed in place of truss assembly 20 to provide an open, cathedral or vaulted ceiling effect.
With reference now to Figures 2 - 5, floor joist trusses 30 seated on concrete wall or pier 31 consist of an upper metal chord tube 32 and a parallel lower metal tension chord tube 34 of lesser depth secured thereto by a plurality of equispaced diagonal members 36 having enlarged end plates 40, 42 formed integral therewith having a size to correspond with the depth of chord tubes 32, 34, as shown most clearly in Figures 2 and 3. Self tapping metal screws 44 secure diagonal members 36 to the chord tubes 32, 34 with plastic or rubberized plastic thermal break sheets or pads 46 insulating the metal components from each other. It may be preferred to cover the exterior faces of wall stud trusses 10 with a thermal break strip 47 (Figure 2) to obviate insulator pads 17.
Figures 6 and 7 illustrate in more detail the construction of diagonal members or 36 having side flanges 50, 52 for rigidity. Figure 7 shows thermal break insulators 46, 48.
Figures 8 - 10 show another embodiment of diagonal member 60 for securement to opposite sides of chord tubes. Each member is a closed tube 62 with connecting brackets or plates 64, 66 extending from opposite sides from opposite ends thereof. Each diagonal member is secured to the chord tubes of stud trusses, joist trusses or rafter trusses from opposite sides of diagonal members 60 by metal screws through plate holes 68.
Figures 11 - 13 illustrate another embodiment of diagonal member 70 with a pair of connecting brackets 72, 74 at each end thereof for straddling a metal chord tube and for securement by self tapping metal screws from both sides of diagonal member 70.
Figure 14 shows another embodiment of diagonal member 80 with end flanges 82, 84 at opposite ends on the same side thereof.
Typical wall studs 10 are formed of galvanized steel tubes 1.5" x 1.5" square interconnected by galvanized steel diagonals 4" to 12" long using steel self tapping screws, or by welds. Floor joists 30, of the same construction, preferably have an upper compression chord tube larger than the lower tension chord tube, e.g. 2.5" x 1.5" upper tube and 1.5" x 1.5" lower tube, or may have 3.5" x 1.5" upper and lower tubes. Roof trusses may be fabricated of 1.5" x 1.5" upper and lower steel tubes, 2.5" x 2.5" upper and lower steel tubes, or 3.0" x 1.5" upper and lower tubes, depending on truss length and anticipated loading. The diagonal members preferably are arranged in V-shaped pairs and connected on opposite sides of the chord tubes to provide torsional rigidity to the trusses.
Thermal insulating pads retard heat transfer and insulate the metal components from each other.
It will be understood that modifications can be made in the embodiment of the invention described herein without departing from the scope and purview of the invention as defined by the appended claims.

The elongated metal tubes preferably are formed of 18 to 26 gauge galvanized steel and the diagonal members of 16 or 18 gauge galvanized steel.
Figure 1 also illustrates a conventional roof truss assembly 20 preferably fabricated from metal components and seated on the upper end 22 of wall stud 10. Roof truss 20 has chord tubes 24 interconnected by screws 21 with insulator pads 23 for a thermal break.
It will be understood that roof rafter trusses similar to wall stud trusses 10 or floor joist trusses 30, to be described, can be employed in place of truss assembly 20 to provide an open, cathedral or vaulted ceiling effect.
With reference now to Figures 2 - 5, floor joist trusses 30 seated on concrete wall or pier 31 consist of an upper metal chord tube 32 and a parallel lower metal tension chord tube 34 of lesser depth secured thereto by a plurality of equispaced diagonal members 36 having enlarged end plates 40, 42 formed integral therewith having a size to correspond with the depth of chord tubes 32, 34, as shown most clearly in Figures 2 and 3.
