Patent Application
20230085421
The present invention relates primarily to a field of steel framing, and more particularly it relates to a novel and useful steel thermal stud for buildings of all types, that provides both structural and non-load bearing characteristics.
In the past, there has been a little change in structural and non-structural steel framing industry since its inception. The steel studs used today are essentially the same design and serve the same functions as when they were first introduced as a “C” shape showing a little advancement. When compared to wood studs, the steel studs have had significant advantages in many areas, but not in thermal transfer which is much worse with the steel studs.
Hence, there is a significant need and void in the market to invent a novel and improved steel thermal stud that provides both structural and non-load bearing characteristics. Also, there is a need to invent a novel and improved steel thermal stud that allows for cantilevered loads mounted perpendicular to a wall plane for items such as televisions for interiors and façade systems for exterior applications.
The present invention is hereinafter disclosed, which provides more thermally efficient steel stud with both, structural and non-load bearing characteristics, and allows for cantilevered loads mounted perpendicular to a wall plane for items such as televisions for interiors and façade systems for exterior applications. The unique characteristics and features of the present invention are, therefore, unrepresented within the conventional steel studs. Hence, the present invention has been disclosed to provide solutions to the aforementioned needs, and to resolve the aforementioned deficiencies in the conventional steel framing systems.
In accordance with the present application, a novel and useful steel thermal stud is herein provided that includes a pair of independent flanges with webs, an insulation material therebetween the independent flanges, and formed plates that hold the independent flanges together via the webs of the flanges.
The steel stud of the present invention may also have an additional nailing wall or flange installed, which provides additional and separated penetration locations for mounting screws, allowing multiple connection points on the screw so that they become “cantilevered” and able to support loads unlike a single walled stud.
The stud may be filled with an insulation material prior to final forming, and the insulation used within the stud may be selected from, but not limited to, foam blocks, rock mineral wool, spray in foam insulation, or other types of insulation.
It may be apparent that the novel and useful Steel Thermal Stud of the present invention has been hereinabove described which works and is used in a manner not consistent with the conventional products and methods.
It is therefore an object of the present application to provide a Steel Thermal Stud with multiple stud walls for a fastener to penetrate in order to prevent the movement of the fastener in any direction, to prevent deformation of the stud wall material, to prevent the fastener from backing out by having additional contact with less potential movement, to provide more pull-out strength and more strip resistance of the fastener during installation.
Another object of the present application is to provide a Steel Thermal Stud that allows the stud to be made as a single unit, or where the flanges with webs are used separately.
Another object of the present application is to provide a Steel Thermal Stud that uses the compressive strength of an insulation to help prevent stud components from moving when pressure is applied to them.
Another object of the present application is to provide a Steel Thermal Stud with a fastener that takes onto itself tensive, compressive, bending, shear and other forces that may otherwise be exerted to a sub-girt and/or stud, when used with either the stud and/or sub-girt of the present application, supporting the sheathing and/or insulation.
Another object of the present application is to provide a Steel Thermal Stud that eliminates the need for resilient channels and/or resilient clips.
Another object of the present application is to provide a Steel Thermal Stud with formed plates which help isolate and absorb vibration and thermal transfer.
Another object of the present application is to provide a Steel Thermal Stud with formed plates which are installed perpendicular to the flanges and webs, diagonally, and/or offset on opposing sides to assist with structural strengths and/or acoustic and thermal transfer reduction.
Another object of the present application is to provide a Steel Thermal Stud which may be used horizontally as a joist or beam, and made with aluminum extrusion in place of steel.
Another object of the present application is to provide a Steel Thermal Stud having formed plates that structurally act to connect both flanges with webs together, assist with axial and twist strengths, provide compressive and tensive strengths for increased bend strength of the complete stud assembly, essentially preventing one flange with webs from moving without the other flange with webs moving.
Another object of the present application is to provide a Steel Thermal Stud having formed plates that act as the limited thermal and acoustic bridging between the flanges with webs.
Another object of the present application is to provide a Steel Thermal Stud with the webs of the flanges being the same length, which may help to eliminate twist of the stud when loads are applied to the stud from any direction.
Another object of the present application is to provide a Steel Thermal Stud with bends in the stud that normally couldn't be made by use of aligned slots. The slots allow bends to be made by rolling the independent flanges over so that no other tooling is needed to make the bends at the aligned slots, allowing for more complex shapes to be made especially when other materials such as insulation may be in the way. For structural strength, and in lieu of the aligned slots, aligned indentations may allow for the same type of bend, with the indentations protruding to the outside of the bend once formed.
Another object of the present application is to provide a Steel Thermal Stud with a rigid insulation to be mounted within a stud part, wherein the rigid insulation may be pre-cut or grooved to consume all air gaps within the completely formed stud.
Another object of the present application is to provide a Steel Thermal Stud which may be utilized as purlin or other shape, and which may be made with fiber reinforced plastic instead of steel.
Another object of the present application is to provide a Steel Thermal Stud with a least expensive sound-proofing wall systems and highest thermal transfer resistance.

Another object of the present application is to provide a Steel Thermal Stud which utilizes any added strengths of the insulation towards the overall structural performance of the stud.
Another object of the present application is to provide a Steel Thermal Stud which utilizes no formed plates to hold the flanges with webs together, for applications such as, non-load bearing conditions, wherein the webs of the flanges with webs may have small interior facing barbs, formed with a punch press, that penetrate the insulation to prevent separation of the flanges with webs, and to keep the insulation positioned within between the flanges with webs.
Another object of the present application is to provide a Steel Thermal Stud with flanges that have indentations with centered holes that may align with a track with matching indentations to self-align the studs at the proper locations when being installed to avoid measuring, and wherein the track may have indented obrounds with obround slots for locations with height differences.
Another object of the present application is to provide a Steel Thermal Stud with at least one secondary flange, wherein an air gap between the flanges acts as an opening for vibration to be trapped, or wherein the at least one secondary flange is a wood or similar product in place of formed steel.
