Definitions
- Steel stud framing such as light or heavy gauge steel framing, is well known and often used in both commercial and residential construction.
- Such framing is typically utilized to construct interior partition walls and generally consists of sill plates or channels located at the top and bottom of a wall, with studs extending between the channels, much like more traditional wooden sill plates and wooden studs.
- Both the sill plates and the studs are typically C-shaped or U-shaped.
- the studs are typically affixed to the channels by mechanical fastening means, such as self-tapping screws.
- the lower-most sheet of drywall is installed first, with the subsequent sheets being placed on top of the lower sheets for temporary support during construction.
- installers will typically place the lower-most sheet of drywall directly on the floor surface adjacent to the sill plate. Because the floor surfaces of construction sites, particularly commercial sites and residential basements, tend to be formed from concrete, moisture may wick through the concrete and into the drywall through capillary action. This situation promotes the formation of mold in the drywall.
- Mold is problematic for drywall in that it causes staining and general discoloration. Mold may also cause the drywall to disintegrate over time, or begin to emit an odor.
- the formation of certain molds may be a health detriment to individuals exposed to the mold or spores therefrom which may travel away from the spore source, for example, by becoming airborne from forced air heating or cooling. Thus, mold in any area of a structure may taint the entire structure. Such health problems may range in minor cases from allergic reactions to actual sicknesses in severe cases.
- Installers with knowledge and concern for the mold growth phenomenon are preferably careful to avoid contact between drywall and concrete floors. To prevent such contact, installers may use drywall shims or wedges between the floor and the drywall during construction. Once the drywall is attached to the studs, the shims or wedges should then be removed to prevent moisture from wicking from the floor to the drywall through the shims or wedges. Often, installers simply leave the shims or wedges in place despite this concern.
- irregularities in the floor surface may also cause contact between the drywall and the floor. For example, even a diligent installer who places shims on each end of a drywall section may encounter an uneven floor which is raised in the middle portion such that the middle portion makes contact with the drywall despite the installer's best efforts. In such cases, additional shims must be provided or the drywall will contact the floor in that middle portion. Use of additional shims slows the installation and affect overall project efficiency.
- Drywall should be placed a minimum of 3 ⁇ 8-inch and preferably approximately 1 ⁇ 2-inch above the floor surface to prevent moisture from the floor surface from wicking into the drywall. These heights also help to keep the drywall dry in the case of unintended spills, floods or the like, or routine cleaning efforts. Even a diligent installer may only place the drywall approximately 1 ⁇ 4-inch or less above the floor when using the prior art methods of temporarily elevating the drywall discussed above. Often, this may still lead to mold growth.

Description
- This application is a continuation of U.S. Application patent application Ser. No. 11/036,711 filed Jan. 14, 2005, now pending, which claims the benefit of the filing date of U.S. Provisional Patent Application No. 60/543,757 filed Feb. 11, 2004, the disclosures of which are hereby incorporated herein by reference.
- Steel stud framing, such as light or heavy gauge steel framing, is well known and often used in both commercial and residential construction. Such framing is typically utilized to construct interior partition walls and generally consists of sill plates or channels located at the top and bottom of a wall, with studs extending between the channels, much like more traditional wooden sill plates and wooden studs. Both the sill plates and the studs are typically C-shaped or U-shaped. The studs are typically affixed to the channels by mechanical fastening means, such as self-tapping screws. Once all of the electrical and mechanical appurtenances have been installed between the studs, drywall may then be attached to the studs, again typically with mechanical fastening means, to complete the wall.
- In a majority of construction projects, the lower-most sheet of drywall is installed first, with the subsequent sheets being placed on top of the lower sheets for temporary support during construction. When installed in this manner, installers will typically place the lower-most sheet of drywall directly on the floor surface adjacent to the sill plate. Because the floor surfaces of construction sites, particularly commercial sites and residential basements, tend to be formed from concrete, moisture may wick through the concrete and into the drywall through capillary action. This situation promotes the formation of mold in the drywall.
- Mold is problematic for drywall in that it causes staining and general discoloration. Mold may also cause the drywall to disintegrate over time, or begin to emit an odor. The formation of certain molds may be a health detriment to individuals exposed to the mold or spores therefrom which may travel away from the spore source, for example, by becoming airborne from forced air heating or cooling. Thus, mold in any area of a structure may taint the entire structure. Such health problems may range in minor cases from allergic reactions to actual sicknesses in severe cases.
- Installers with knowledge and concern for the mold growth phenomenon are preferably careful to avoid contact between drywall and concrete floors. To prevent such contact, installers may use drywall shims or wedges between the floor and the drywall during construction. Once the drywall is attached to the studs, the shims or wedges should then be removed to prevent moisture from wicking from the floor to the drywall through the shims or wedges. Often, installers simply leave the shims or wedges in place despite this concern.
- Other methods of temporarily supporting the first sheet of drywall off of the floor surface during installation of the drywall are also commonly utilized. One such method is the use of a bent steel wedge. In this method, an installer places one end of a long and slender piece of steel which is curved beneath the drywall such that the curved ends face up. The installer then steps on the free end to lower the free end and elevate the end beneath the drywall. Once the drywall is elevated, the installer may affix the drywall to the studs and then remove the bent steel wedge.
- This method is problematic as it is often difficult to coordinate use of a bent steel wedge with one's foot while simultaneously holding and attempting to affix a piece of drywall to the studs. Additional helpers may be useful, but their use affects overall project efficiency by requiring additional man-hours of labor.
- Regardless of the method utilized by the installer, irregularities in the floor surface may also cause contact between the drywall and the floor. For example, even a diligent installer who places shims on each end of a drywall section may encounter an uneven floor which is raised in the middle portion such that the middle portion makes contact with the drywall despite the installer's best efforts. In such cases, additional shims must be provided or the drywall will contact the floor in that middle portion. Use of additional shims slows the installation and affect overall project efficiency.
- Even where drywall is placed above the surface of a floor, it is often placed with too little of a gap to avoid becoming moist. Drywall should be placed a minimum of ⅜-inch and preferably approximately ½-inch above the floor surface to prevent moisture from the floor surface from wicking into the drywall. These heights also help to keep the drywall dry in the case of unintended spills, floods or the like, or routine cleaning efforts. Even a diligent installer may only place the drywall approximately ¼-inch or less above the floor when using the prior art methods of temporarily elevating the drywall discussed above. Often, this may still lead to mold growth.
- Thus, it would be beneficial to provide a sill plate which incorporates features which inherently prevent drywall from contacting a floor surface, and which can maintain a proper elevation above a floor surface on a consistent basis.
- The present invention overcomes the shortcomings of the prior art by providing a sill plate having features designed to elevate drywall on a consistent basis from a floor surface.
- In accordance with one aspect of the present invention, there is provided a sill plate comprising a base section, a first wall associated with the base section, and a first shelf associated with the first wall, wherein the first shelf is adapted to support drywall.
- The sill plate may further comprise a second wall associated with the base section, the second wall opposed from the first wall. The sill plate may further comprise a second shelf associated with the second wall, the second shelf adapted to support drywall. The first wall and the second wall may have exterior surfaces facing away from each other, wherein the first shelf may be associated with the exterior surface of the first wall and the second shelf may be associated with the exterior surface of the second wall. The first wall, the base section, and the second wall may form a generally C-shaped cross section.
- The base section may be relatively flat so as to form a base section plane, the first shelf extending from the first wall along a plane generally parallel to the base section plane.
- The first shelf may be located above the base section. The location may be approximately ½-inch above the base section.
- The first wall may be formed integrally with the base.
- The sill plate may further comprise a first flap associated with the first wall, the first shelf formed from a portion of the first flap.
- In accordance with further aspects of the present invention, a sill plate for steel stud framing may comprise a base section having a first edge and a second edge, a first wall extending generally perpendicular to the first edge of the base, and a first shelf extending from the first wall along a plane generally parallel to a plane formed by the base section, wherein the first shelf is adapted to support drywall.
- The sill plate may further comprise a second wall extending generally perpendicular to the second edge of the base section. The sill plate may further comprise a second shelf extending from the second wall along a plane generally parallel to a plane formed by the base section, the second shelf adapted to support drywall. The first wall, the base section, and the second wall may form a generally C-shaped cross section.
- The first shelf may be located above the base section. The location may be approximately ½-inch above the base section.
- In accordance with still further aspects of the present invention, a method of erecting a wall may comprise installing a sill plate against a floor surface, the sill plate comprising a base section, a first wall extending from the base section, and a first shelf associated with the first wall, the first shelf extending along a plane substantially parallel to a plane formed by the base section, installing studs adjacent the first wall, supporting a first sheet of drywall on the first shelf above the floor surface, and affixing the first sheet of drywall to the studs.
- The sill plate may further comprise a second wall extending from the base section and a second shelf associated with the second wall, the second shelf extending along a plane substantially parallel to a plane formed by the base section, the method further comprising supporting a second sheet of drywall on the second shelf above the floor surface, and affixing the second sheet of drywall to the studs. The step of installing studs adjacent the first wall may locate the studs between the first wall and the second wall. The step of supporting drywall on the first shelf may elevate the drywall above the floor surface at least ¼-inch.
- In accordance with additional aspects of the present invention, a kit of components for use in the construction of steel stud framing may comprise a sill plate, the sill plate comprising a base section, a first wall associated with the base section, a first shelf associated with the first wall, the first shelf adapted to support drywall, and at least one stud.

Although not shown, thestuds 24 are typically attached to thefirst wall 16 andsecond wall 18 with fastening means. Conventionally, such fastening means comprise mechanical fasteners, such as self-tapping screws. However, chemical fastening systems may also be utilized. Such systems include various glues and multi-part epoxies. -
Studs 24 are generally C-shaped, and may comprise afirst side 26 and asecond side 28 spanning between acentral portion 30. As shown inFIG. 1 , thefirst side 26 ofstud 24 is generally installed adjacent to thefirst wall 16 ofsill plate 10 with thesecond side 28 of the stud installed adjacent to thesecond wall 18 of the sill plate, such that thecentral portion 30 ofstud 24 spans across the length “L” of the sill plate. - Non-C-shaped
studs 24 may also be provided. For example, in some framing systems, the base portion of the stud, or that portion which connects to thesill plate 10, may be formed from a conventional wood stud while the upper section is C-shaped. In addition, conventional wood studs may be utilized. Notwithstanding, in a conventional framing system, the studs are preferably C-shaped. -
Drywall 32, depicted as resting on thefloor 12 in the conventional manner, is then secured to the exterior of thesecond side 28 ofstud 24 with fastening means, such as self-tappingscrews 34. Similarly, a second piece of drywall (not shown) may be secured to the exterior offirst side 26 of thestud 24. - As previously discussed, because floor surfaces 12 may be formed from concrete, moisture may wick from the floor into the
drywall 32. Even if thefloor 12 is relatively free of moisture, moisture may reach thedrywall 32 through other means if the drywall is installed close to the floor. For example, spills, either accidental or from routine cleaning, may moisten the portions of thedrywall 32 closest to thefloor 12. These situations promote the formation of mold in thedrywall 32. - As shown in
FIGS. 2 and 3 , asill plate 110 configured in accordance with certain aspects of the present invention may include features designed to prevent thedrywall 132 from resting on thefloor 112, irrespective of the skills or desires of the installer. Thesill plate 110 may comprise ahorizontal base 114 with afirst wall 116 andsecond wall 118 extending vertically therefrom. In this regard, thesill plate 110 shown inFIGS. 2 and 3 is much like theconventional sill plate 10 shown inFIG. 1 . - However, the
sill plate 110 may also be provided with features designed to elevate thedrywall 132 on a consistent basis from thefloor surface 112. Rather than includingfirst flap 20 andsecond flap 22 bent toward the inside of thesill plate 10 as is included in the conventional sill plate shown inFIG. 1 , thesill plate 110 shown inFIGS. 2 and 3 and configured in accordance with certain aspects of the present invention may include afirst flap 120 and asecond flap 122 bent approximately 180 degrees toward the outside of thesill plate 110. Thus, portions offlaps walls - As shown in
FIG. 2 ,first flap 120 may form afirst shelf 136 andsecond flap 122 may form asecond shelf 138. Thefirst shelf 136 may extend outward from thefirst wall 116 along a plane substantially parallel to a plane passing throughbase 114. Likewise,second shelf 138 may extend outward from thesecond wall 118 along a plane parallel to a plane passing throughbase 114. Each of thefirst shelf 136 andsecond shelf 138 is preferably raised from thefloor 112 above the level ofbase 114 by a height “h.” In certain embodiments, theshelves floor 112. In a preferred embodiment, theshelves floor 112. In other embodiments, theshelves floor 112. In still further embodiments, theshelves floor 112. Additional configurations are also possible, depending on the design criteria. - In addition, the
shelves floor 112. For example,first shelf 136 may be ½-inch above thefloor 112 whilesecond shelf 138 may be ¾-inch above the floor. In other embodiments,first shelf 136 may be ¼-inch above the floor whilesecond shelf 138 may be ½-inch above the floor. Other such configurations are also possible. - Because the heights “h” of the
shelves drywall 132 installed on a particular project may be affixed to the studs at controlled heights above thefloor surface 112. In this regard, it is preferred that adjacent lengths ofsill plate 110 on a given project are configured identically such that the height ofdrywall 132 resting thereon is consistent. - The
shelves shelves drywall 132 at least on a temporary basis during construction, until the drywall is affixed to thestuds 124 by other means. - As shown in
FIG. 2 , astud 124 may be fitted within thefirst wall 116 andsecond wall 118 ofsill plate 110, with thefirst side 126 andsecond side 128 of thestud 124 attached with a self-tappingscrew 134 or other fastening means to thefirst wall 116 andsecond wall 118 ofsill plate 110, respectively. - Once the
sill plate 110 andstuds 124 are assembled,drywall 132 may be placed uponfirst shelf 136 andsecond shelf 138, as shown inFIG. 3 . Thedrywall 126 may then be attached tostud 124 with self-tapping screws (not shown) or other fastening means. - Because of the presence of the
shelves drywall 132 properly. For example, if thedrywall 132 is not placed directly upon theshelves floor 112, once the drywall is fastened to thestud 124, the lower portion of the drywall adjacent the shelves will be forced to curve around the shelf and will at least be visually unappealing, and may fracture due to the stress. Accordingly, even an unaware contractor will be forced to utilize thesill plate 110 of the present invention in the correct manner, as the sill plate itself facilitates proper installation of drywall regardless of the knowledge base of the installer. - Accordingly, the present invention provides for the proper installation of drywall in a steel stud framing system without slowing the efficiency of construction. In fact, because the use of shims or bent steel wedges is not required, and the installer has a convenient place to rest drywall during installation, the system should speed up construction in instances where the installer is cognizant of mold and would have attempted to lift the drywall from the floor surface using other methods.
- In other embodiments, it will be appreciated that the sill plate may be formed with only a single shelf so the sill plate may be placed against an existing wall. Such a
sill plate 210 is shown inFIG. 4 . As shown, thesill plate 210 may include ashelf 238 associated with thesecond wall 218 much like thesill plate 110 shown and described with respect toFIG. 2 and afirst flap 220 associated with thefirst wall 216 much like thefirst flap 20 of theconventional sill plate 10 shown and described with respect toFIG. 1 . In this case,wall 218 may be abutted directly against an existing wall. Thesill plate 210 may also be configured to have a shelf associated with thefirst wall 216 and a flap associated with thesecond wall 218 in a mirror image of thesill plate 210 shown inFIG. 4 . - In yet another configuration shown in
FIG. 5 , asill plate 310 in accordance with certain aspects of the present invention may include only asingle wall 318 extending from thebase 314. In this regard, thewall 318 may include ashelf 338, much like theshelf 238 shown and described with respect toFIG. 4 . - In order to add structural support, any of the
sill plates FIG. 5 depictsflanges 340 extending between theshelf 338 and thewall 318 in order to add structural support to the shelf. Theflanges 340 may formed integrally with thesill plate 310, or may be affixed thereto utilizing mechanical or chemical means. Commonly, theflanges 340 may be tack welded to asill plate 310. -
FIG. 5 also depicts alip 342 extending fromshelf 338. Although it is preferred not to include such alip 342, one may be provided if deemed necessary. It will be appreciated that such alip 342 may help to prevent thedrywall 132 from slipping off of theshelf 338 between the time the drywall is rested on the shelf and is affixed to the studs. As an alternative, or in conjunction therewith, theshelf 338 may include surface treatment or surface irregularities designed to increase friction between the shelf and the drywall, to help prevent the drywall from falling off of the shelf between the time the drywall is rested on the shelf and the time the dry wall is affixed to the studs. Such surface treatments and irregularities may include dimples, bumps, ridges, or the like. In preferred embodiments, nolip 342, surface treatments, or surface irregularities are required. -
FIG. 6 depicts a side view of thesill plate 310 shown inFIG. 5 . As shown most clearly inFIG. 6 , thelip 342, if so provided, is preferably relatively short such that an installer may easily place the drywall between the lip and theflap 322. Although depicted as in a solid triangular configuration, it will be appreciated that theflange 340 may be configured in many alternative manners, such as an open triangle or other geometric and non-geometric configurations. In addition, theflange 340 may simply comprise a single bead of welding material to provide a measure of strength to theshelf 338, if so required. - The sill plates shown and described in accordance with the present invention may be formed from metals such as steel or aluminum, plastics, composites, or any other suitable material. Depending on the material, the sill plate may be bent, roll formed, extruded, molded, or formed in other suitable manners.
- The preferred manner of forming the sill plate is through roll forming of coiled stock steel. By using the roll forming process, a continuous length of coiled stock may be bent or otherwise formed into shape by feeding the stock between successive pairs of rolls that increasingly shape the material into the desired cross-section. As the continuous length of sill plate exits the roll forming machine, a cutoff machine may cut the continuous roll into predetermined lengths, typically in the range of 8 feet to 16 feet. This method is desirable for mass-produced, quality controlled sill plates.
- Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only in that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit of the invention as hereinafter claimed.
