ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a framing element particularly adapted for use in light load applications such as residential and commercial structures.
In the recent years, there has been a development in the technology of press-joint connection of metal parts by cold forming. In such technology, a punch of, for example, a type sold by Eckold AG pushes respective surfaces of light gauge steel (or other metal) against each other and then, using high impact hydraulic or pneumatic means, creates a cold-formed joint, that is, a securement between such surfaces of the light gauge steel members.
Tools for effecting such press-joining of light gauge steel in order to accomplish framing and other applications may be accomplished through the use of mobil hand-held or hand-guided tools usable during in-house and on-site construction. The present invention is therefore directed to a truss framing. element particularly adapted to take advantage of such contemporary techniques of the press-joining light gauge steel elements to each other.
SUMMARY OF THE INVENTION
The instant invention relates to a light-gauge truss framing element which comprises a longitudinal constructional chord or beam having a uniform generally T-shaped cross-section, in which a vertical portion of said cross-section defines a web of the beam and a transverse horizontal portion thereof defines a symmetric flange. Therein, the beam comprises a material having a thickness in a range of about ten to about twenty-two gauge and having a yield strength in a range of about thirty-six to about fifty-five kips per square inch. The web, in transverse cross-section, resembles a compressed V-shaped element which may be selectably reinforced through the use of rods or stiffening elements internal or external to the apex of the V-shaped web.
It is an object of the invention to provide a longitudinal constructional beam having particular application in light gauge steel framing, utilizing press-joining technology.
It is another object to provide a light gauge truss framing element.
It is a further object of the invention to provide a light gauge constructional beam including a reinforced web portion thereof.
The above and yet other objects and advantages of the present invention will become apparent from the hereinafter set forth Brief Description of the Drawings, Detailed Description of the Invention, and claims appended herewith.
