CONTINUOUS METAL BUILDING FRAMING MEMBER

Abstract

A continuous metal building framing member may be cut and bent to form at least one wall member and at least one roofing member. The continuous metal building framing member may eliminate or reduce the use of web connector clips, rafter ties, and stud-to-rafter or top plate-to-rafter clip connections while expediting wall and roof assembly in light gauge cold formed steel framed building structures. The framing members may be specific pre-notched steel framing members, notched at predetermined bend locations, with remaining web and flange material to be structurally significant after bending, while simultaneously dictating points and extend of bending. The framing members may be 1) pre-notched framing members to be folded at notched locations to pre-determined angles which provide roof pitch angles and elevation; 2) entire wall and rafter sections formed from one continuous framing member; and 3) rapidly screwed or welded together with the remaining overlapping web material to permanently fix the desired angles.

Description

BACKGROUND OF THE INVENTION

The present invention relates to framing materials and, more particularly, to a combination of wall studs and rafters composed of one continuous cold formed framing member.

Traditional light gauge steel framed structures are composed of individual members, cut to length, with various end-cut angles, held together with connector clips and track members. These members are then fastened together with screws or welded to secure individual connections. These conventional structures requires substantial work in cutting and attaching framing members together with, for example, web connector clips, rafter ties and stud-to-rafter or top plate-to-rafter clip connections.

As can be seen, there is a need for a metal building framing member that may eliminate or reduce the need for clips or other attachment members for forming building framing members.

SUMMARY OF THE INVENTION

In one aspect of the present invention, a building framing member comprises at least one stud member and at least one rafter member continuously formed from a single piece of a metal framing member; a notch and a slot cut into a portion of the building framing member, the notch and the slot adapted to create a bend line, the bend line adapted to permit the building framing member to bend therealong to align the stud member and the rafter member at a predetermined angle.

In another aspect of the present invention, a continuous metal framing member comprises a first stud member; a first rafter member formed continuously with the first stud member, the first rafter member spanning from the first stud member to a roof ridge of a building assembled with the continuous metal framing member; a second rafter member formed continuously with the first rafter member, the second rafter member spanning from the roof ridge to a second stud member, wherein the second stud member is formed continuously with the second rafter member.

These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

Various inventive features are described below that can each be used independently of one another or in combination with other features.

Broadly, an embodiment of the present invention provides a continuous metal building framing member that may be cut and bent to form at least one wall member and at least one roofing member. The continuous metal building framing member may eliminate or reduce the use of web connector clips, rafter ties, and stud-to-rafter or top plate-to-rafter clip connections while expediting wall and roof assembly in light gauge cold formed steel framed building structures. The framing members may be specific pre-notched steel framing members, notched at predetermined bend locations, with remaining web and flange material to be structurally significant after bending, while simultaneously dictating points and extend of bending. The framing members may be 1) pre-notched framing members to be folded at notched locations to pre-determined angles which provide roof pitch angles and elevation; 2) entire wall and rafter sections formed from one continuous framing member; and 3) rapidly screwed or welded together with the remaining overlapping web material to permanently fix the desired angles.

Referring to FIGS. 1 through 7, a framing member 10 may be formed from a continuous piece of metal framing material to form both stud members 12 and rafter members 14. The framing member 10 may be a cold formed steel (CFS) framing member, typically a C-shape stud member per ASTM C645 or ASTM C955.

A stud-to-rafter joint 16 may be formed by cutting and notching the framing member 10 as shown in FIGS. 2 and 3. A notch in the stud member 12 may define the wall height. A first slot 20a may be cut in a long side of the framing member 10 and a second slot 20b may be cut in the short end of the C-shaped framing member 10 as shown in FIG. 3. A bend line 22 may be where the rafter member 14 bends away from the stud member 12. As shown in FIGS. 5 and 6, when the framing member 10 is bent, a fastening mechanism 32, such as rivets, bolts, a weld, a clinch, or the like, may connect the overlapping portions of the framing member 10 to secure the stud-to-rafter joint 16 at a desired angle.

A rafter peak junction 18 may be formed by cutting and notching the framing member 10 as shown in FIGS. 2 and 4. A notch 26 in the rafter member may be made on an interior side of the framing member 10. The notch 26 may be formed equidistant from each side of a bend line 30 of the rafter member 14. A slot 24 may be cut across the long side of the framing member 10 and a notch 28 may be cut out of the short end of the C-shaped framing member 10 as shown in FIG. 4. As shown in FIG. 7, when the framing member 10 is bent, the notch 28 may allow the framing member 10 to abut together to help secure the desired angle at the roof peak. Similar to that shown in FIGS. 5 and 6, the overlapping material of the framing member 10 may be secured together to help secure the desired angle at the roof peak.

The notches (such as notches 28) and slots (such as slots 20a, 20b, and 24) may be manufactured in predetermined locations as a component of the framing member's manufacture, either as a finished or a partially finished notch/slot combination and in multiple configurations and/or cut in the field as needed.

While the above description and drawings describes a continuous framing member including a stud member, a rising rafter member, a falling rafter member and another stud member, the present invention may include any number of continuous framing members. For example, the present invention may include a single stud member and a single rafter member adapted to be connected to a separate ridge member, such as an engineered ridge joist.

It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
