Abstract
Description
- The invention relates to the field of construction materials and specifically to metal studs to replace conventional vertical wood studs, such as 50,8x101,6mm (2" x 4") wood studs (nominal dimensions) used to form walls having a unique configuration on the ends of the metal studs that meets structural requirements for walls yet allows carpenters to assemble wall sections at least as conveniently and rapidly as they can using wood studs, without additional training or new tools, to form a less expensive and higher quality frame for a wall.
- It has been common construction practice for many years to form rooms in houses, offices and other buildings by the use of partitions or walls. Walls or sections of walls in houses, offices or other buildings have been typically constructed by use of opposing horizontal wood plates, consisting typically of 50,8x101,6mm (2" x 4") lumber, one each being adjacent to the floor and ceiling respectively, between which vertical wood studs are attached with a certain uniform separation, typically 406,4mm (16"), between each of the vertical studs, with the connection being made between the top and bottom horizontal wood plates and the vertical wood studs by means of toe nailing.
- Metal has advantages over wood as a material for vertical studs in that metal will not warp over time, will not be subject to termites and other vermin, and will consistently provide a flat surface to which material, such as drywall, forming the vertical surface of the wall may be attached, resulting in a perfectly flat wall and a metal stud is lighter than a wood stud.
- Notwithstanding the advantages of metal, wood has been the material of choice for the use as vertical studs in substantial part because wood studs have been easier for carpenters to use in assembling sections of walls. That assembly typically occurs on the floor of the building under construction or remodeling. After assembly of a section of wall, the section is tilted or lifted into a vertical position and moved to its intended location. Prior to the invention, carpenters have been unable to use metal vertical studs because of the additional time, tools or materials required for their use in assembling wall sections.
- While the prior art contains several references disclosing metal framing structures and studs, none of these references disclose or suggest the combination of features that comprise the present invention. E.g. US-A- 2 699 669, U.S. Patent No. 3,482,369 issued on December 3, 1969 to Burke discloses a novel opening in vertical metal studs to receive a horizontal member to provide bracing to achieve lateral stiffness. Further, U.S. Patent No. 1,867,489 issued October 9, 1930 to Eckett et al. discloses a horizontal bracing stud, adjustable to permit positioning between studs, also forming a fire block. Still further, U.S. Patent No. 5,157,883 issued on October 7, 1992 to Mayer discloses a metal stud responsive to the problem of earthquake shock by providing a metal-to-metal fastening system. The claims only relate to a clip, spaced intervally along the vertical section of the stud, to inhibit buckling. Finally, in the U.S. Patent No. 4,001,983 issued January 11, 1977 to Daniels, there is disclosed a wall system in which a strip of particle board is interposed between the ceiling (top) and floor (bottom) plates. The disclosed stud is a fully-enclosed stud with rectangular cross-section. Each end of the stud penetrates the particle board to achieve positioning; thus the particle board, not the plates are penetrated, and any weakening of the plates, caused by the weight being borne, is avoided. Two opposing faces of both ends of the stud are nailed to the floor and ceiling plates. Corrugated portions assure uniform distribution of the weight load, and contribute to stiffness.
- The invention is a metal stud having a particular configuration at each end to allow efficient connection to wood plates to be permanently positioned along the floor and along the ceiling, by a carpenter without additional training or new tools, to interconnect these metal and wood members to provide a non-weight-bearing wall frame of superior quality.
- An object of this invention is to provide a metal stud to replace the conventional wood stud, typically of 50,8x101,6mm (2" x 4") (nominal dimensions).
- Another object of this invention is to provide a metal stud that can be used by carpenters, and without the use of new tools and without any significant additional training, to assemble sections of walls or partitions in a manner similar to and at least as efficient as the manner of assembly of conventional wood studs. That typical manner of assembly is to align and connect, by nailing or stapling, the top and bottom plates to the studs, on a floor, and then to lift or tilt the assembly into its permanent position.
- Another object of this invention is to provide a metal stud that has realistic commercial utility to replace wood studs for use in assembling walls or partitions of superior quality.
- Other objects of this invention are to provide a stud made from material for which there is a dependable supply at a stable price. Prices of wood have been subject to changes in price and availability depending upon uncontrollable events such as hurricanes, floods, and the preferred nesting habits of the spotted owl. The metal stud of this invention may be made of recycled steel. It also has the additional advantage of being lighter than a wood stud.
- The objects of this invention are achieved by providing a steel stud of three walls with a [-shaped or open rectangular construction, that attaches to wood plates as easily as wood studs may be attached. The inventive vertical steel stud is made by conventional shaping of sheet metal generally into the form of a wood stud of conventional dimensions and having an open rectangular, [-shaped cross section and thus having two parallel side walls perpendicular to a central wall. Only one of the side walls has an extension, to form a leg or flange, of a length approximately equal to or less than the thickness (typically 50,8mm (2") nominal) of a wooden plate, on each end of that side wall. The distance between the inner surfaces of the two parallel sides is equal to the width (typically 101,6mm (4") nominal) of the top and bottom wooden plates.
- The other side wall of the metal stud has no such extension on either end, and is of a length approximately equal to the intended distance between the exposed surface of the top and bottom plates. At each end of the central wall portion of the stud there is a flange, integral to the central portion of the stud and outwardly perpendicular thereto.
- The stud can be made by forming the sheet steel into the desired open, rectangular shape, making a cut along each seam of a length equal to or slightly less than the thickness of the top and bottom wood plates, forming a flange, on each end of the central wall portion, by bending the cut portion of such central wall outwardly and perpendicular to the surface of the central wall portion of the stud, and cutting the flange from both ends of one of the sides of the stud.
- The accompanying drawings can be briefly described as follows.
- Figures 1A and 1B are perspective views of the interconnection between a metal stud, [10], having a block-[-shaped or open, rectangular cross section, and conventional floor and ceiling wood plates, [32], wherein the end of the central section of each end is bent outwardly at the floor and ceiling plates, to form a horizontal flange [34, 36] to interface with the surface of the wood plate [32], and an extension on each end of a single side of the stud provides a nailing flange [26, 28] to the surface of the lower (floor) and upper plates.
- In the preferred embodiment, the metal stud is formed to have exterior dimensions generally similar to those of the conventional finished wood stud, having a depth or thickness of a nominal 50,8mm (2") and actual depth or thickness of approximately 38,1mm (1½"), and a width of a nominal 101,6mm (4") and actual width of approximately 88,9mm (3½"), and is made from sheet metal made from recycled steel of approximately 0.508mm (0.02 inch) in thickness. The stud is formed into the desired open rectangular shape having dimensions substantially equal to those of the conventional 50,8x101,6mm (2" x 4") wood stud and with the distance between the parallel side walls of the stud being substantially equal to the outside width dimensions of the 50,8x101,6mm (2 x 4), or approximately 82,55mm (3¼"). The sides are approximately 25,4mm (1") in depth. The length of the stud is approximately 2387,6mm (94") measured between the outside of the central flanges. The side wall of the stud having the extensions serving as flanges on each end thus is approximately 38,1mm (1½") by 2438,4mm (96"), the stud's side wall without flanges is approximately 38,1x2387,6mm (1½" x 94"), and the stud's central wall is approximately 88,9x2387,6mm (3½" x 94").
- While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the following claims.
