Definitions
- This disclosure relates generally to construction elements for residential and commercial buildings and, more specifically, elements and methods for creating rounded corners with a greater radius to provide softer, flowing corners within a constructed building, as compared with square corners or rounded corners with a small radius such as 1.5 inches or less.
- the construction element may be used both vertically and horizontally in any space that requires a corner or where a bend or curve is desired in a wall, ceiling, or the like (hereinafter collectively referred to as “wall”).
- elongated bends may be substantially different than the straight walls that simply form a straight plane.
- the elongated curved walls are often constructed with wood or metal studs to form the desired curvature of the wall. Multiple studs may be required to manipulate to the desired curvature. Drywall is then also required to be bent at the proper curvature as well to be fastened to the studs. Often the wood studs and/or the drywall must be water treated, so as not to break and so the proper curvature can be made to the desired curvature of the wall.
- the disclosure relates to construction elements and methods for making bends and curves in constructed walls and at wall intersections.
- the construction elements allow for a simple “drop in place” solution for creating aesthetically pleasing walls with large-radius curves in the design of the constructed building.
- the construction elements may be utilized to provide bends and curves in walls without needing to wet and bend drywall and/or wooden studs.

- FIG. 37 is a perspective view of a corner construction element.
- a construction element for forming a corner of an interior surface of a building, the interior surface including wall panels attached to framing studs.
- the construction element may include: a corner-forming surface that is shaped to extend, in a cross-sectional view, between two separate wall panels, such that ends of the corner-forming surface, as viewed in the cross-sectional view, substantially match respective corners of the wall panels.
- FIG. 1 is a blown-apart view of wall structure 100 including a corner construction element 102 .
- the wall structure 100 includes studs 104 , which may be standard 2 ⁇ 4 or 2 ⁇ 6 wood or metal studs commonly used in the construction industry, for example, according to known framing techniques.
- Interior wall panels 1062 are attached to an inside corner formed by the studs 104
- exterior wall panels 1064 are attached to an outside corner formed by the studs 104 .
- “Exterior” and “outside” in this context include surfaces that are inside a building structure, and do not necessarily refer to an exterior wall of a building structure.
- the wall structure 100 may be the structure of an interior wall of a building, which may or may not be a load-bearing wall (i.e., a wall that bears the weight of structural elements above it).
- the walls panels 1062 and 1064 may be commonly used drywall panels, sometimes called gypsum panels, such as SHEETROCK brand drywall panels. Other types of wall panels are also acceptable.
- the corner construction element 102 attaches to an outside corner formed by the studs 104 as shown.
- Fasteners 108 which may be standard drywall nails or drywall screws, pass through a wall panel 1064 , through a leg portion of the corner construction element 102 as described in more detail below, and into a stud 104 .
- the corner construction element 102 may be pre-attached to the studs 104 by one or more fasteners 108 prior to installation of the wall panels 1064 to hold the corner construction element 102 in place while the wall panels 1064 are positioned and attached.
- the corner construction element 102 may be positioned relative to the studs 104 , then one or more fasteners 108 passed through one or both leg portions of the corner construction element 102 , then the wall panels 1064 positioned relative to the corner construction element 102 and studs 104 , then other fasteners 108 passed through respective ones of the wall panels 1064 , through respective ones of the leg portions of the corner construction element 102 , and into respective ones of the studs 104 .
- the corner construction element 102 can be held in place without pre-attaching it to the studs 104 as described above, the pre-attachment step can be omitted.
- FIG. 2 is a plan view of the corner construction element 102 .
- the corner construction element 102 includes leg portions 1022 (fastener strips) and a curved portion 1026 (corner-forming surface).
- Step portions 1024 connect respective ones of the leg portions 1022 to the curved portion 1026 .
- the width of the step portions 1024 is preferably equal to or slightly larger than the thickness of standard drywall sheets.
- Standard drywall sheets typically have a thickness of 1 ⁇ 2′′ or 5 ⁇ 8′′ for vertical walls, or 3 ⁇ 8′′ or 1 ⁇ 2′′ for ceilings.
- step portions 1024 be slightly larger than the thickness of the wall panels 1064 to be used is that when drywall tape and drywall compound (also known as “drywall mud”) are applied over the seam between the corner construction element 102 and the wall panels 1064 , there is a depression formed at the seam to accommodate the tape and compound.
- the step portions 1024 may be in a range of about 1/16′′ to about 1 ⁇ 8′′ larger than the thickness of the wall panels 1064 to be used.
- a facing layer 1028 may be applied along the outer curvature of the curved portion 1026 , and may be attached to the curved portion 1026 by adhesive, for example.
- the facing layer 1028 may be of heavy paper material, for example, or of fiberglass or thin plastic material such as vinyl or PVC, or of a composite of two or more of these materials or other materials.
- the facing layer 1028 may be applied as a spray-on layer that hardens to a desired texture.
- An advantage of the facing layer 1028 is that the outer layer of the corner construction element 102 may be similar or identical to the outer layer of the wall panels 1064 in terms of characteristics such as texture, absorption or the like, making it easier to create a uniform appearance around the outer corner of the wall structure 100 when priming, painting or the like.
- the facing layer 2018 may be omitted, and the outer corner of the wall structure 100 may be finished by applying primer, paint or other coating material directly to the material of the curved portion 1026 .
- the corner construction element 102 may be made of a thin, somewhat rigid material, such as metal, fiberglass, or plastic material such as vinyl or PVC, or of a composite of two or more of these materials or other materials. It may be bent into its final shape from a flat piece of material, or extruded into the desired shape.
- FIG. 3 is a plan view of a corner construction element 102 that is the same as that described in connection with FIG. 2 , except that the corner construction element 102 of FIG. 3 additionally has wing portions 1029 extending from ends of the curved portion 1026 .
- the flexible wing portions 1029 may be an extension of the material of the facing layer 1028 .
- the wing portions 1029 may be a separate layer, of material the same as or different from that of the facing layer 1028 , such as paper material, fiberglass, or plastic material such as vinyl or PVC, or of a composite of two or more of these materials or other materials, attached to the curved portion 1026 or to the step portions 1024 .
- the wing portions 1029 When attached as a separate layer to the curved portion 1026 , the wing portions 1029 may be attached to the outer surface of the facing layer 1028 by adhesive, for example, or may be sandwiched between the curved portion 1026 and the facing layer 1028 .
- the curved portion 1026 , the wing portions 1029 , the step portions 1024 and the leg portions 1022 may be formed of the same material.
- these portions may all be formed of plastic material, such as vinyl or PVC, and formed together as one piece by extrusion or another forming method.
- the wing portions 1029 may have an adhesive layer, covered by a release layer 1030 that may be peeled off to expose the adhesive layer, so that the wing portions 1029 may be adhered to the wall panels 1064 as described hereafter.
- the wing portions 1029 may be attached to the wall panels 1064 using a thin layer of drywall compound, according to known techniques.
- FIG. 4 is a plan view of an assembled wall structure including a corner construction element 102 .
- the corner construction element 102 may have a radius up to about 4 inches, and preferably at least 2 inches, such as any radius from 2 to 4 inches in increments of 1 ⁇ 8′′.
- the inside curved surface of the corner construction element 102 may be in contact with the corner stud 104 as shown, for greater rigidity of the finished corner of the wall structure.
- the corner stud 104 is shown having a rounded corner to reflect the fact that most 2 ⁇ 4 wood studs have slightly rounded edges (although the depiction of the rounded edge may be somewhat exaggerated in this drawing), and the corner construction element 102 may contact the rounded edge instead of the corner of a theoretically perfectly rectangular-cross-section stud.
- Metal studs may be closer to perfectly rectangular in cross section, and for metal stud applications a corner construction element 102 may be used that has a slightly smaller radius of curvature to better fit against the corner of a metal corner stud 104
- fasteners 108 pass through the exterior wall panels 1064 , through the leg portions 1022 , and into the studs 104 .
- the interior wall panels 1062 are attached directly to the studs 104 by additional fasteners 108 .
- Additional studs 104 may be spaced along the intersecting wall sections as depicted, and may have a center-to-center spacing of 16′′ or 24′′, for example, according to common framing techniques.
- the four studs 104 forming the corner of the frame may be attached together using framing nails (not shown) or other suitable fasteners.
- the wall panels 1062 and 1064 may have tapered edges, as in common in drywall panels, to form a recess for accommodating drywall tape and drywall compound to facilitate the drywall finishing process.

- the facing layer 2026 may be similar or identical to the outer layer of the wall panels 1064 in terms of characteristics such as texture, hardness, absorption or the like, making it easier to create a uniform appearance around the outer corner of the wall structure when priming, painting or the like.
- the facing layer 2026 may be omitted, and the outer corner of the wall structure may be finished by applying primer, paint or other coating material directly to the material of the corner construction element 202 .

In other embodiments, the fastener-engaging elements 2022 and 2024 may be made of other material sprayed on or attached by adhesive. Some embodiments may not include fastener-engaging elements 2022 and/or 2024 , if the material of the body 2020 can adequately hold the fastener, or if the body 2020 is attached to the studs directly by an adhesive acting as a fastener, for example.
- a recess 2028 may be formed at each end of the curved surface of the body 2020 to accommodate drywall tape and drywall compound that cover the seam between the corner construction element 202 and wall panels.

- 2 ⁇ 4 walls and 2 ⁇ 6 walls are mentioned here because they are common in the construction industry, but of course any other desired wall thickness is acceptable, in which case the radius of the corner construction element 102 would be adjusted appropriately.
- the radius of curvature is selected to be in a range such that the minimum thickness of the body 2020 , which generally will be at the middle of the curved surface, is sufficient for the body 2020 not to easily break during handling and installation.
- fasteners 108 pass first through respective ones of wall studs 104 and then into respective ones of the fastener-engaging elements 2022 .
- the fasteners 108 may be common nails, or, for a more secure holding effect, the fasteners 108 may be commonly known ring-shank nails and/or cement-coated nails, or screws, for example.
- a strong adhesive can be used as a fastener.
- Wall panels 1062 and 1064 may be attached to the studs 104 as shown using fasteners 108 , and the wall panels 1062 may be attached to the fastener-engaging element 2024 using additional fasteners 108 .
- the wall panels 1062 and 1064 may have tapered edges, as is common in drywall panels, to form a recess for accommodating drywall tape and drywall compound to facilitate the drywall finishing process. Finishing of the outside corner (e.g., applying drywall tape and drywall compound to the seams between the corner construction element 202 and the wall panels 1064 ) is particularly facilitated when the tapered wall panel edges abut a corner construction element 202 that includes recesses 2028 as described above.
- FIG. 16 is a plan view of an assembled wall structure including a corner construction element 202 .
- the structure of FIG. 16 is the same as that of FIG. 15 , except that the corner construction element 202 includes wing portions 2029 as shown in FIG. 14 .

- FIG. 17 is a plan view of another type of corner construction element 202 .
- This corner construction element 202 includes a body 2020 that is a solid body as defined above, but includes hollow sections 2048 within the body 2020 .
- the body 2020 includes a plurality of webs 2040 that define end walls including stud attachment surfaces 2042 , an inner wall including an inside surface 2044 , and an outer wall including an outside surface 2046 . Additional webs, not depicted here, may be provided, e.g., between the inner wall and the outer wall, and/or between the inner wall and the end walls, and/or between the outer wall and the end walls.
- the webs 2040 may be provided in any desired number and/or configuration.
- the webs 2060 may be in a repeating “W” configuration that defines smaller approximately triangular hollow sections 2062 .
- Such a “W” configuration that defines approximately triangular hollow sections can provide a strength advantage, and/or an acoustic advantage (e.g., tapping on a construction element with such a “W” configuration may not produce as much of a “hollow” or “drum” sound as tapping on a construction element with square hollow sections).
- the webs 2040 may be provided in any desired thickness.
- the web thickness may be optimized for any desired variables or parameters, and may vary depending on the type of material used. For example, if the body 2020 is made of foam material, the webs 2040 may be thicker than if the body is made of solid polymer material. Additionally, the webs 2040 defining the end walls including the stud attachment surfaces 2042 may be thicker than other webs, in order to provide more material to which the fasteners 108 may attach.
- the web thickness preferably is as thin as practical in order to reduce the amount of material used, and thereby to reduce weight and cost.
- plastic or resin molding or the like will appreciate that a certain minimum thickness will exist depending on the type of material used, the type of equipment used (e.g., pumps for pumping liquid resin or plastic or the like), the length of material flow paths in any molding or casting process, or the like. Additionally, a certain minimum thickness will exist from the perspective of strength and/or rigidity, which will also depend on the type of material used, the number and/or geometric configuration of webs used, and/or the like.
- the corner construction element 202 of FIG. 17 may be formed in any suitable manner, including any suitable plastic or resin molding or casting process.
- extrusion molding is one possible molding method.

- the corner construction element 202 of FIG. 17 may include recesses 2028 as described above in connection with FIG. 13 , and/or may include a facing layer 2026 (not shown in FIG. 17 ) as described above in connection with other embodiments, and/or may include wing portions 2029 (not shown in FIG. 17 ) as described above in connection with other embodiments.
- the corner construction element 202 of FIG. 17 may be assembled into a wall structure in the same manner as the corner construction element 202 shown in FIG. 12 , with the fasteners 108 passing through studs 104 and into the end walls of the body 2020 .
- the material of the body 2020 can adequately hold the fastener (such as a solid polymer material), or if the body 2020 is attached to the studs directly by an adhesive acting as a fastener, for example, no fastener-engaging elements 2022 are necessary.
- FIG. 18 is a side view of a corner construction element 203 , as viewed in the direction of arrow A 1 of FIG. 17 , installed between a floor F and a ceiling C.
- the corner construction element 203 can correspond to any of the corner construction elements 202 described above, or any of the corner construction elements described hereafter. If interior walls including the corner construction element 203 are constructed before a ceiling structure is built above them, then it is easy to install the corner construction element 203 as a single piece.
- a problem can occur when installing a corner construction element 203 between a floor F and a ceiling C, if both the floor F and the ceiling C are in place before the interior walls are assembled. Specifically, as the corner construction element 203 is raised to an upright position, corners of the ends of the corner construction element 203 can catch on the floor F and the ceiling C, making it difficult or impossible to raise the corner construction element 203 all the way to the upright position without damage to the corner construction element 203 , the ceiling C, and/or the floor F.
- FIG. 20 illustrates a corner construction element 203 comprising multiple sections (here, two sections 203 A and 203 B) being installed between the floor F and the ceiling C.

- the upper section 203 B may be installed first, and then the lower section 203 A may be installed by sliding the lower section 203 A between the upper section 203 B and the floor F in a horizontal direction.
- Providing the corner construction element 203 in multiple sections can also lead to other advantages, such as convenience and/or cost reduction in packaging and/or shipping.
- FIG. 21 is a side view of a portion of a corner construction element 203 C that illustrates another option for addressing the problem shown in FIG. 19 .
- one end of the corner construction element 203 C is tapered, at angle ⁇ as shown.
- the tapered end may be formed at the time of manufacturing, or may be cut by an installer at the time of installation.
- a suitable angle ⁇ may be calculated in advance based on the overall geometry and size of the corner construction element 203 C, or may be determined by trial and error. In the former case, for example, an angle ⁇ of about 22° has been calculated to be effective in at least one embodiment. In the latter case, an installer may cut the taper at a small angle, and then re-cut it at a larger angle if the small angle is not sufficient to allow the corner construction element 203 C to raise to an upright position between the floor F and the ceiling C.
- the tapered end allows the corner construction element 203 C to be raised to an upright position without corners of the ends of the corner construction element 203 catching on the floor F and the ceiling C.
- a small gap will be present at the upper end of the corner construction element 203 C, but an installer or construction worker can cover this gap with trim, molding (e.g., crown molding that is known in the constructions arts), drywall compound or stucco, or the like.

- any suitable known or later-developed formation method may be used.
- construction adhesive may be used, either alone or in connection with other methods and/or structures described above, for connecting together multiple sections of a corner construction element.
- corrugated nails may also be used, either alone or in connection with other methods and/or structures described above, for connecting together multiple sections of a corner construction element. The corrugated nails would be tapped or pressed in to the corner construction element horizontally, spanning across the seam between, e.g., first and second sections of the corner construction element that are placed vertically adjacent to each other.
- the multiple sections of a corner construction element are indirectly connected together, and may not require a direct connection between them.

Abstract
A construction element is provided for forming a corner of a surface of a building, the surface including wall panels attached to framing studs. The construction element includes: a corner-forming surface that that is shaped to extend, in a cross-sectional view, between two separate wall panels, such that ends of the corner-forming surface, as viewed in the cross-sectional view, substantially match respective corners of the wall panels. The construction element may be provided in multiple sections that are placed end to end and connected together.
Description
- This application claims the priority benefit of provisional application No. 62/571,673 filed Oct. 12, 2017, and of U.S. non-provisional patent application Ser. No. 16/100,395, filed Aug. 9, 2018, the disclosures of which are incorporated herein by reference in their entirety.
- This disclosure relates generally to construction elements for residential and commercial buildings and, more specifically, elements and methods for creating rounded corners with a greater radius to provide softer, flowing corners within a constructed building, as compared with square corners or rounded corners with a small radius such as 1.5 inches or less. The construction element may be used both vertically and horizontally in any space that requires a corner or where a bend or curve is desired in a wall, ceiling, or the like (hereinafter collectively referred to as “wall”).
- In all constructed buildings there are places within the building where at least two walls intersect. When the walls intersect it is necessary to put a corner on those walls to hide the exposed place where often two pieces of drywall come together on a wood or metal stud, or other type of vertical brace (hereinafter referred to as “stud”). In many instances a rounded bead or square bead is utilized to lie over or across the two pieces of dry wall to create a smooth corner. A smooth corner may be rounded or it may be sharp but is intended to cover the edge of two edges of dry wall where multiple walls intersect.
- In some construction buildings there are bends in a wall, or curves in a wall that are gradual and rounded and the wall bends around a corner having a relatively large radius, such as 2″ or more. These elongated bends may be substantially different than the straight walls that simply form a straight plane. The elongated curved walls are often constructed with wood or metal studs to form the desired curvature of the wall. Multiple studs may be required to manipulate to the desired curvature. Drywall is then also required to be bent at the proper curvature as well to be fastened to the studs. Often the wood studs and/or the drywall must be water treated, so as not to break and so the proper curvature can be made to the desired curvature of the wall.
- Current construction elements would make it difficult, if not impossible to create sharper bends around a corner of two walls intersecting but less sharp then a long curvature of an entire length of a wall. Specifically within residential construction, creating a large-radius bend or curve around a corner becomes very difficult given the current products typically available for construction.
- The disclosure relates to construction elements and methods for making bends and curves in constructed walls and at wall intersections. The construction elements allow for a simple “drop in place” solution for creating aesthetically pleasing walls with large-radius curves in the design of the constructed building. The construction elements may be utilized to provide bends and curves in walls without needing to wet and bend drywall and/or wooden studs.

The construction element may include: a corner-forming surface that is shaped to extend, in a cross-sectional view, between two separate wall panels, such that ends of the corner-forming surface, as viewed in the cross-sectional view, substantially match respective corners of the wall panels.
-
FIG. 1 is a blown-apart view ofwall structure 100 including acorner construction element 102. Thewall structure 100 includesstuds 104, which may be standard 2×4 or 2×6 wood or metal studs commonly used in the construction industry, for example, according to known framing techniques.Interior wall panels 1062 are attached to an inside corner formed by thestuds 104, andexterior wall panels 1064 are attached to an outside corner formed by thestuds 104. “Exterior” and “outside” in this context include surfaces that are inside a building structure, and do not necessarily refer to an exterior wall of a building structure. Thus, thewall structure 100 may be the structure of an interior wall of a building, which may or may not be a load-bearing wall (i.e., a wall that bears the weight of structural elements above it). - The
walls panels - The
corner construction element 102 attaches to an outside corner formed by thestuds 104 as shown.Fasteners 108, which may be standard drywall nails or drywall screws, pass through awall panel 1064, through a leg portion of thecorner construction element 102 as described in more detail below, and into astud 104. Thecorner construction element 102 may be pre-attached to thestuds 104 by one ormore fasteners 108 prior to installation of thewall panels 1064 to hold thecorner construction element 102 in place while thewall panels 1064 are positioned and attached. That is, first, thecorner construction element 102 may be positioned relative to thestuds 104, then one ormore fasteners 108 passed through one or both leg portions of thecorner construction element 102, then thewall panels 1064 positioned relative to thecorner construction element 102 andstuds 104, thenother fasteners 108 passed through respective ones of thewall panels 1064, through respective ones of the leg portions of thecorner construction element 102, and into respective ones of thestuds 104. Alternatively, if thecorner construction element 102 can be held in place without pre-attaching it to thestuds 104 as described above, the pre-attachment step can be omitted. -
FIG. 2 is a plan view of thecorner construction element 102. Thecorner construction element 102 includes leg portions 1022 (fastener strips) and a curved portion 1026 (corner-forming surface).Step portions 1024 connect respective ones of theleg portions 1022 to thecurved portion 1026. The width of thestep portions 1024 is preferably equal to or slightly larger than the thickness of standard drywall sheets. Standard drywall sheets typically have a thickness of ½″ or ⅝″ for vertical walls, or ⅜″ or ½″ for ceilings. An advantage to having the width of thestep portions 1024 be slightly larger than the thickness of thewall panels 1064 to be used is that when drywall tape and drywall compound (also known as “drywall mud”) are applied over the seam between thecorner construction element 102 and thewall panels 1064, there is a depression formed at the seam to accommodate the tape and compound. For example, thestep portions 1024 may be in a range of about 1/16″ to about ⅛″ larger than the thickness of thewall panels 1064 to be used. - A facing
layer 1028 may be applied along the outer curvature of thecurved portion 1026, and may be attached to thecurved portion 1026 by adhesive, for example. The facinglayer 1028 may be of heavy paper material, for example, or of fiberglass or thin plastic material such as vinyl or PVC, or of a composite of two or more of these materials or other materials. In some embodiments, the facinglayer 1028 may be applied as a spray-on layer that hardens to a desired texture. An advantage of the facinglayer 1028 is that the outer layer of thecorner construction element 102 may be similar or identical to the outer layer of thewall panels 1064 in terms of characteristics such as texture, absorption or the like, making it easier to create a uniform appearance around the outer corner of thewall structure 100 when priming, painting or the like. However, in some embodiments, the facing layer 2018 may be omitted, and the outer corner of thewall structure 100 may be finished by applying primer, paint or other coating material directly to the material of thecurved portion 1026. - The
corner construction element 102 may be made of a thin, somewhat rigid material, such as metal, fiberglass, or plastic material such as vinyl or PVC, or of a composite of two or more of these materials or other materials. It may be bent into its final shape from a flat piece of material, or extruded into the desired shape. -
FIG. 3 is a plan view of acorner construction element 102 that is the same as that described in connection withFIG. 2 , except that thecorner construction element 102 ofFIG. 3 additionally haswing portions 1029 extending from ends of thecurved portion 1026. Theflexible wing portions 1029 may be an extension of the material of the facinglayer 1028. Alternatively, thewing portions 1029 may be a separate layer, of material the same as or different from that of the facinglayer 1028, such as paper material, fiberglass, or plastic material such as vinyl or PVC, or of a composite of two or more of these materials or other materials, attached to thecurved portion 1026 or to thestep portions 1024. When attached as a separate layer to thecurved portion 1026, thewing portions 1029 may be attached to the outer surface of the facinglayer 1028 by adhesive, for example, or may be sandwiched between thecurved portion 1026 and the facinglayer 1028. In some embodiments, thecurved portion 1026, thewing portions 1029, thestep portions 1024 and theleg portions 1022 may be formed of the same material. For example, these portions may all be formed of plastic material, such as vinyl or PVC, and formed together as one piece by extrusion or another forming method. - The
wing portions 1029 may have an adhesive layer, covered by arelease layer 1030 that may be peeled off to expose the adhesive layer, so that thewing portions 1029 may be adhered to thewall panels 1064 as described hereafter. Alternatively, instead of using an adhesive layer, thewing portions 1029 may be attached to thewall panels 1064 using a thin layer of drywall compound, according to known techniques. -
FIG. 4 is a plan view of an assembled wall structure including acorner construction element 102. Thecorner construction element 102 may have a radius up to about 4 inches, and preferably at least 2 inches, such as any radius from 2 to 4 inches in increments of ⅛″. The inside curved surface of thecorner construction element 102 may be in contact with thecorner stud 104 as shown, for greater rigidity of the finished corner of the wall structure. Thecorner stud 104 is shown having a rounded corner to reflect the fact that most 2×4 wood studs have slightly rounded edges (although the depiction of the rounded edge may be somewhat exaggerated in this drawing), and thecorner construction element 102 may contact the rounded edge instead of the corner of a theoretically perfectly rectangular-cross-section stud. Metal studs may be closer to perfectly rectangular in cross section, and for metal stud applications acorner construction element 102 may be used that has a slightly smaller radius of curvature to better fit against the corner of ametal corner stud 104. - As depicted in
FIG. 4 , and as described above,fasteners 108 pass through theexterior wall panels 1064, through theleg portions 1022, and into thestuds 104. Theinterior wall panels 1062 are attached directly to thestuds 104 byadditional fasteners 108.Additional studs 104 may be spaced along the intersecting wall sections as depicted, and may have a center-to-center spacing of 16″ or 24″, for example, according to common framing techniques. The fourstuds 104 forming the corner of the frame may be attached together using framing nails (not shown) or other suitable fasteners. - The
wall panels step portions 1024 of thecorner construction element 102 may be slightly larger than the thickness of thewall panels 1064. If desired, differentcorner construction elements 102 with different widths of thestep portions 1024 may be provided, depending on whetherwall panels 1064 with tapered edges or untapered edges are to be used. -
FIG. 5 is a plan view of a partially assembled wall structure including acorner construction element 102. In this structure, a slightly different framing technique is used, in which threestuds 104 are used to form the corner of the frame, and onestud 104 is offset with respect to the other two. In this construction, the radius of thecurved portion 1026 of thecorner construction element 102 may be larger than in the structure shown inFIG. 4 . For example, the radius of thecurved portion 1026 of thecorner construction element 102 may be up to about 6 inches, and preferably at least 2 inches, such as any radius from 2 to 6 inches in increments of ⅛″. Although not depicted,interior wall panels 1062 may be attached directly to thestuds 104 at the inside corner as inFIG. 4 . -
FIG. 6 is a plan view of an assembled wall structure including acorner construction element 102. The structure ofFIG. 6 is the same as that ofFIG. 4 , except that thecorner construction element 102 includeswing portions 1029 as shown inFIG. 3 . Thewing portions 1029 have been attached to thewall panels 1064 after installation of thewall panels 1064, thereby covering the seam between thewall panels 1064 and thecorner construction element 102. -
FIG. 7 is a plan view of acorner construction element 102′. Instead of acurved portion 1026, the corner-formingsurface 1026 connecting thestep portions 1024 is straight instead of curved. It will be appreciated that an alternate framing technique, such as the one depicted inFIG. 5 , will be needed in the case of thecorner construction element 102′. - Although the corner construction elements shown in
FIGS. 1-7 are designed for corners of walls that intersect each other substantially at 90°, corner construction elements may be made for corners of walls that intersect each other at other angles, such as 30°, 45° or 60°. -
FIG. 8 is a plan view of an endcap construction element 102″. The endcap construction element 102″ hasleg portions 1022 that are substantially parallel to each other, instead of being substantially perpendicular to each other as in thecorner construction elements 102 shown inFIGS. 1-6 . Thecurved portion 1026 of the endcap construction element 102″ extends in a substantially semicircular or elliptic shape and connects thestep portions 1024, and the facinglayer 1028 extends along the entirety of thecurved portion 1026. -
FIG. 9 is a plan view of an assembled wall structure including the endcap construction element 102″. The wall structure may be the structure of a partition wall that ends in a free space, instead of joining at its end to another wall section, or may be the side of of a doorway or window opening. The inside curved surface of the endcap construction element 102″ may be in contact with theend stud 104 as shown, for greater rigidity of the finished end cap of the wall structure. -
FIG. 10 is a plan view of an endcap construction element 102″. The endcap construction element 102′″ hasleg portions 1022 that are substantially parallel to each other, as with theelement 102″ shown inFIGS. 8-9 . Theportion 1026 of the endcap construction element 102′″ extends in a substantially trapezoidal shape or other polygonal shape and connects thestep portions 1024, and the facinglayer 1028 extends along the entirety of theportion 1026. The endcap construction element 102″ may be incorporated in a wall structure that is otherwise similar to that shown inFIG. 9 . -
FIG. 11 is a plan view of an endcap construction element 102″ that is the same as that shown inFIG. 8 , except that that the endcap construction element 102 includeswing portions 1029 as shown inFIG. 3 . The endcap construction element 102″ may be incorporated in a wall structure that is otherwise similar to that shown inFIG. 9 , and thewing portions 1029 may be attached to thewall panels 1064 after installation of thewall panels 1064, thereby covering the seam between thewall panels 1064 and endcap construction element 102″. -
FIG. 12 is a blown-apart view of wall structure including acorner construction element 202. Thecorner construction element 202 has fastener-engaging elements 2022 (fastener strips), and also a fastener-engagingelement 2024.Fasteners 108 pass first through respective ones ofwall studs 104 and then into respective ones of the fastener-engagingelements 2022.Wall panels studs 104 as shown usingfasteners 108, and thewall panels 1062 may be attached to the fastener-engagingelement 2024 using additional fasteners 108 (which may be of a different length, such as a shorter length, than the fasteners that attach the wall studs to the corner construction element 202). - A facing
layer 2026 may be applied along the outer curvature (corner-forming surface, which is not separately labeled in this embodiment) of thecorner construction element 202, and may be attached to thecorner construction element 202 by adhesive, for example. The facinglayer 2026 may be of heavy paper material, for example, or any other known or later-developed material, and may be a spray-on layer that hardens to a desired texture and/or hardness. For example, the facinglayer 2026 may have a hardness greater than that of the underlying material, such as in the case of a foam material that is described hereafter. The facinglayer 2026 may have an adhesive layer, covered by arelease layer 2027 that may be peeled off to expose the adhesive layer, so that the facinglayer 2026 may be adhered to thecorner construction element 202. Alternatively, therelease layer 2027 may be omitted. - An advantage of the facing
layer 2026 is that the outer layer of thecorner construction element 202 may be similar or identical to the outer layer of thewall panels 1064 in terms of characteristics such as texture, hardness, absorption or the like, making it easier to create a uniform appearance around the outer corner of the wall structure when priming, painting or the like. However, in some embodiments, the facinglayer 2026 may be omitted, and the outer corner of the wall structure may be finished by applying primer, paint or other coating material directly to the material of thecorner construction element 202. -
FIG. 13 is a plan view of thecorner construction element 202. Thecorner construction element 202 includes abody 2020 that may be formed of foam material, such as polystyrene foam material. Thebody 2020 is a solid body, meaning that it is not formed from a sheet of thin material that has been formed into a desired shape, and/or that thebody 2020 occupies an entire space of a corner joint, such that no stud of one wall that is part of the corner connects directly to a stud of another wall that is part of the corner. (In contrast, for example, theconstruction elements 102 shown inFIGS. 1-6 are not “solid bodies” as that term is used in this disclosure.) The polystyrene foam material may be in the form of expanded polystyrene (also called “EPS”) or extruded polystyrene (also called “XPS”). Other foam materials include polyethylene foam. Another possible material for thebody 2020 is a molded paper pulp material, such as the paper pulp material that some egg cartons are made of. Another possible material for thebody 2020 is solid polymer material, including any natural or synthetic polymers. Such polymers include (i) plastics such as acrylic, polycarbonate, polyethylene (PE), including low-density polyethylene (LDPE) and high-density polyethylene (HDPE), polypropylene, polyethylene terephthalate (PETE or PET), polyvinyl chloride (PVC), and acrylonitrile-butadiene-styrene (ABS), and (ii) any suitable plant-based resin or other resin material. The above-described foam materials may also be considered as polymer materials, but for purposes of this disclosure, the term “solid polymer material” will be used to refer to polymers such plastics and resins other than the foam materials listed above. Another possible material for thebody 2020 is wood, including wood fiber products such as particle board or fiber board (including low density fiber board (LDF) or medium density fiber board (MDF). Such wood fiber products can be manufactured by known or later-developed processes including mixing wood particles together with resin and other additives and then forming them into a desired shape using heated molds or dies, for example. Other or later-developed materials are also possible, provided that they can hold the desired shape. Thebody 2020, when formed of foam material, may be cut from a larger block of foam material, by a known method such as hot wire cutting, or may be formed directly into its final shape during an extrusion forming process, for example. In short, any known or later-develop materials may be used, and any known or later-developed processes may be used for forming the selected material into the desired shape. - In embodiments in which the
body 2020 is made of foam material or another material than can be cut by a hot wire, spaces for the fastener-engagingelements 2022 can also be made by a hot wire.Spaces 2023 show paths through which a hot wire has passed before forming spaces for the respective fastener-engagingelements 2022. In other embodiments, foam or another material can be molded around the fastener-engagingelements 2022. - The fastener-engaging
element 2024 may be attached to thebody 2020 by an adhesive, for example. Additionally, although the fastener-engagingelements 2022 are shown and described above as passing through an interior of thebody 2020, in other embodiments they may be attached to exterior faces of thebody 2020 by an adhesive, for example, and not pass through the interior of thebody 2020. - The fastener-engaging
elements elements elements 2022 and/or 2024, if the material of thebody 2020 can adequately hold the fastener, or if thebody 2020 is attached to the studs directly by an adhesive acting as a fastener, for example. The subsequent application of drywall tape and/or compound, particularly when wing portions are included as described below, further strengthens the connection between thecorner construction element 202. Thus, particularly if the final wall assembly is not expected to be subjected to heavy pressure or jostling, for example, the fastener-engaging elements may be omitted. - At each end of the curved surface of the
body 2020 there may be formed arecess 2028 to accommodate drywall tape and drywall compound that cover the seam between thecorner construction element 202 and wall panels. -
FIG. 14 is a plan view of acorner construction element 202 that is the same as that described in connection withFIG. 13 , except that thecorner construction element 202 ofFIG. 14 additionally haswing portions 2029 extending from ends of the curved surface of thebody 2020. Theflexible wing portions 2029 may be an extension of the material of the facinglayer 2026. Alternatively, thewing portions 2029 may be a separate layer, of material the same as or different from that of the facinglayer 2026, attached to the curved surface of thebody 2020 or to the flat end surfaces of thebody 2020. When attached as a separate layer to the curved surface of thebody 2020, thewing portions 1029 may be attached to the outer surface of the facinglayer 2026, or may be sandwiched between thebody 2020 and the facinglayer 2026. - The
wing portions 2029 may have an adhesive layer, covered by arelease layer 2030 that may be peeled off to expose the adhesive layer, so that thewing portions 2029 may be adhered to thewall panels 1064 as described hereafter. Alternatively, instead of using an adhesive layer, thewing portions 2029 may be attached to thewall panels 1064 using a thin layer of drywall compound, according to known techniques. -
FIG. 15 is a plan view of an assembled wall structure including acorner construction element 202. Thecorner construction element 102 may have a radius of at least about 2 inches and up to about 16 inches, such as any radius from 2 to 16 inches in increments of ⅛″, for 2×4 walls, or at least about 2 inches and up to about 30 inches, such as any radius from 2 to 30 inches in increments of ⅛″, for 2×6 walls. 2×4 walls and 2×6 walls are mentioned here because they are common in the construction industry, but of course any other desired wall thickness is acceptable, in which case the radius of thecorner construction element 102 would be adjusted appropriately. In each case, the radius of curvature is selected to be in a range such that the minimum thickness of thebody 2020, which generally will be at the middle of the curved surface, is sufficient for thebody 2020 not to easily break during handling and installation. - As depicted in
FIG. 15 , and as described above,fasteners 108 pass first through respective ones ofwall studs 104 and then into respective ones of the fastener-engagingelements 2022. Thefasteners 108 may be common nails, or, for a more secure holding effect, thefasteners 108 may be commonly known ring-shank nails and/or cement-coated nails, or screws, for example. In some embodiments, a strong adhesive can be used as a fastener. -
Wall panels studs 104 as shown usingfasteners 108, and thewall panels 1062 may be attached to the fastener-engagingelement 2024 usingadditional fasteners 108. - The
wall panels corner construction element 202 and the wall panels 1064) is particularly facilitated when the tapered wall panel edges abut acorner construction element 202 that includesrecesses 2028 as described above. -
FIG. 16 is a plan view of an assembled wall structure including acorner construction element 202. The structure ofFIG. 16 is the same as that ofFIG. 15 , except that thecorner construction element 202 includeswing portions 2029 as shown inFIG. 14 . Thewing portions 1029 have been attached to thewall panels 1064 after installation of thewall panels 1064, thereby covering the seam between thewall panels 1064 and thecorner construction element 202. -
FIG. 17 is a plan view of another type ofcorner construction element 202. Thiscorner construction element 202 includes abody 2020 that is a solid body as defined above, but includeshollow sections 2048 within thebody 2020. Thebody 2020 includes a plurality ofwebs 2040 that define end walls including stud attachment surfaces 2042, an inner wall including aninside surface 2044, and an outer wall including anoutside surface 2046. Additional webs, not depicted here, may be provided, e.g., between the inner wall and the outer wall, and/or between the inner wall and the end walls, and/or between the outer wall and the end walls. Thewebs 2040 may be provided in any desired number and/or configuration. For example, rather than defininghollow sections 2062 having the depicted shapes, thewebs 2060 may be in a repeating “W” configuration that defines smaller approximately triangularhollow sections 2062. Such a “W” configuration that defines approximately triangular hollow sections can provide a strength advantage, and/or an acoustic advantage (e.g., tapping on a construction element with such a “W” configuration may not produce as much of a “hollow” or “drum” sound as tapping on a construction element with square hollow sections). - The
webs 2040 may be provided in any desired thickness. The web thickness may be optimized for any desired variables or parameters, and may vary depending on the type of material used. For example, if thebody 2020 is made of foam material, thewebs 2040 may be thicker than if the body is made of solid polymer material. Additionally, thewebs 2040 defining the end walls including the stud attachment surfaces 2042 may be thicker than other webs, in order to provide more material to which thefasteners 108 may attach. The web thickness preferably is as thin as practical in order to reduce the amount of material used, and thereby to reduce weight and cost. Those skilled in the arts of plastic or resin molding or the like will appreciate that a certain minimum thickness will exist depending on the type of material used, the type of equipment used (e.g., pumps for pumping liquid resin or plastic or the like), the length of material flow paths in any molding or casting process, or the like. Additionally, a certain minimum thickness will exist from the perspective of strength and/or rigidity, which will also depend on the type of material used, the number and/or geometric configuration of webs used, and/or the like. - The
corner construction element 202 ofFIG. 17 may be formed in any suitable manner, including any suitable plastic or resin molding or casting process. For example, extrusion molding is one possible molding method. However, the disclosure is not limited to any particular forming method. - The
corner construction element 202 ofFIG. 17 may includerecesses 2028 as described above in connection withFIG. 13 , and/or may include a facing layer 2026 (not shown inFIG. 17 ) as described above in connection with other embodiments, and/or may include wing portions 2029 (not shown inFIG. 17 ) as described above in connection with other embodiments. - The
corner construction element 202 ofFIG. 17 may be assembled into a wall structure in the same manner as thecorner construction element 202 shown inFIG. 12 , with thefasteners 108 passing throughstuds 104 and into the end walls of thebody 2020. As described above, if the material of thebody 2020 can adequately hold the fastener (such as a solid polymer material), or if thebody 2020 is attached to the studs directly by an adhesive acting as a fastener, for example, no fastener-engagingelements 2022 are necessary. -
FIG. 18 is a side view of acorner construction element 203, as viewed in the direction of arrow A1 ofFIG. 17 , installed between a floor F and a ceiling C. Thecorner construction element 203 can correspond to any of thecorner construction elements 202 described above, or any of the corner construction elements described hereafter. If interior walls including thecorner construction element 203 are constructed before a ceiling structure is built above them, then it is easy to install thecorner construction element 203 as a single piece. - However, as shown in
FIG. 19 , a problem can occur when installing acorner construction element 203 between a floor F and a ceiling C, if both the floor F and the ceiling C are in place before the interior walls are assembled. Specifically, as thecorner construction element 203 is raised to an upright position, corners of the ends of thecorner construction element 203 can catch on the floor F and the ceiling C, making it difficult or impossible to raise thecorner construction element 203 all the way to the upright position without damage to thecorner construction element 203, the ceiling C, and/or the floor F. - To avoid such a problem,
FIG. 20 illustrates acorner construction element 203 comprising multiple sections (here, twosections lower section 203A may be installed, and subsequently, theupper section 203B may be installed by sliding theupper section 203B between thelower section 203A and the ceiling C in a horizontal direction, as shown by arrow A2. Alternatively, theupper section 203B may be installed first, and then thelower section 203A may be installed by sliding thelower section 203A between theupper section 203B and the floor F in a horizontal direction. - Providing the
corner construction element 203 in multiple sections can also lead to other advantages, such as convenience and/or cost reduction in packaging and/or shipping. -
FIG. 21 is a side view of a portion of a corner construction element 203C that illustrates another option for addressing the problem shown inFIG. 19 . Specifically, one end of the corner construction element 203C is tapered, at angle α as shown. The tapered end may be formed at the time of manufacturing, or may be cut by an installer at the time of installation. A suitable angle α may be calculated in advance based on the overall geometry and size of the corner construction element 203C, or may be determined by trial and error. In the former case, for example, an angle α of about 22° has been calculated to be effective in at least one embodiment. In the latter case, an installer may cut the taper at a small angle, and then re-cut it at a larger angle if the small angle is not sufficient to allow the corner construction element 203C to raise to an upright position between the floor F and the ceiling C. - As shown in
FIG. 22 , the tapered end allows the corner construction element 203C to be raised to an upright position without corners of the ends of thecorner construction element 203 catching on the floor F and the ceiling C. After installation, a small gap will be present at the upper end of the corner construction element 203C, but an installer or construction worker can cover this gap with trim, molding (e.g., crown molding that is known in the constructions arts), drywall compound or stucco, or the like. -
FIG. 23 is a perspective view of thesection 203B of acorner construction element 203 described above, andFIG. 24 is a perspective view of thesection 203A of acorner construction element 203 described above. To attach thesections section 203A is provided with one or more protrusions 2050 (which may be cylindrical as shown, or any other desired shape), andsection 203A is provided with one ormore recesses 2052 configured to receive the one ormore protrusions 2050. Theprotrusions 2050 and therecesses 2052 may be formed during an initial manufacturing of thesections protrusions 2050 may be attached to thesection 203A by screws or other fasteners, or by being inserted into holes drilled in thesection 203A, and therecesses 2052 may be formed by drilling or the like. - If the
sections protrusions 2050 and therecesses 2052, thesections FIG. 19 above. To address this situation, an end of one of the sections, e.g., thesection 203B, may be tapered as described above in connection withFIGS. 21 and 22 . -
FIG. 25 is a perspective view of first andsecond sections slots 2060 formed in ends of thesections keys 2062, with roughly an hourglass-shaped cross section, that slide into theslots 2060 and lock thesections sections FIG. 20 , as described above, and then locked together by inserting thekeys 2062. Keys and slots with different cross sections may also be suitable. For example, keys and slots with a square or rectangular cross section may be used. Although keys and slots with a square or rectangular cross section would not lock thesections sections sections -
FIG. 26 is a perspective view of first andsecond sections section 203B), (ii) an end surface of the one of the sections that faces an end surface of the other section (in this case,section 203A), and (iii) the end surface of other section (in this case,section 203A). Although not depicted, pilot holes may be provided in advance for thefasteners 2070, and recesses may be provided at upper ends of the pilot holes so that heads of the fasteners can be accommodated within the recesses and not protrude from exterior surfaces of the corner construction element. Also, although not depicted, thesections hollow sections 2048 as shown and described above in other embodiments. -
FIG. 27 is a perspective view of first andsecond mating sections 203A′ and 203B′ of a corner construction element that connect together. In this embodiment, the connection structure includesprotrusions 2080A onsection 203A′, which interlock withcomplementary protrusions 2080B onsection 203B′. As in the embodiment shown inFIGS. 25 and 26 , thesections 203A′ and 203B′ can be installed as shown inFIG. 20 , as described above, by sliding one horizontally relative to the other. In addition to having theprotrusions FIG. 26 and described above. - Also, although not depicted, the
sections 203A′ and 203B′ may havehollow sections 2048 as shown and described above in other embodiments. The hollow sections may either extend through theprotrusions ends sections 203A′ and 203B′ by solid end plates that include theprotrusions sections 203A′ and 203B′ by plastic welding, construction adhesive, screws, or any other suitable method and/or structure, or (ii) may be formed integrally with thesections 203A′ and 203B′. In the case of integrally forming the solid end plates with thesections 203A′ and 203B′, any suitable known or later-developed formation method may be used. - Although specific methods and/or structures for connecting together multiple sections of a corner construction element together have been described above with reference to
FIGS. 23-27 , various other methods and/or structures are also possible. For example, construction adhesive may be used, either alone or in connection with other methods and/or structures described above, for connecting together multiple sections of a corner construction element. As another example, corrugated nails may also be used, either alone or in connection with other methods and/or structures described above, for connecting together multiple sections of a corner construction element. The corrugated nails would be tapped or pressed in to the corner construction element horizontally, spanning across the seam between, e.g., first and second sections of the corner construction element that are placed vertically adjacent to each other. As another example, by being separately attached to studs, the multiple sections of a corner construction element are indirectly connected together, and may not require a direct connection between them. However, it typically will be preferable to have a direct connection between the multiple sections, so that they do not become misaligned with each other due to warping of the studs, inadvertent impact from a person or object, or the like. -
FIG. 28 is a plan view of an assembled wall structure including an endcap construction element 202″. The wall structure may be the structure of a partition wall that ends in a free space, instead of joining at its end to another wall section, or may be the side of a doorway or window opening. The endcap construction element 202″ is similar to thecorner constructions elements 202 described above, except that thebody 2020″ of the endcap construction element 202″ has a curved surface that extends between edges of twowall panels 1064 that are substantially parallel to each other. The curved surface in this embodiment may be substantially semicircular, for example, or may be elliptic. Like thebody 2020 of thecorner constructions elements 202, thebody 2020″ may be formed of foam material or solid polymer material, or any other suitable material, and/or may have a facinglayer 2026, and/or may have hollow sections and webs. - Additionally, as shown, two fastener-engaging
elements 2022 may be provided, although in some embodiments only a single fastener-engagingelements 2022, or more than two fastener-engagingelements 2022, may be provided. In some embodiments, the fastener-engagingelements 2022 are omitted. -

Thewing portions 2029 have been attached to thewall panels 1064 after installation of thewall panels 1064, thereby covering the seam between thewall panels 1064 and the endcap construction element 202″. -
FIG. 31 is a plan view of an assembled wall structure including acorner construction element 204, which is designed for a non-90° corner, such as a 45° corner. As with thecorner construction elements 202 described above,studs 104 are connected to thecorner construction element 203 by passingfasteners 108 through thestuds 104 and into fastener-engagingelements 2022. Although not depicted inFIG. 31 , thecorner construction element 204 may have a facing layer and/or wing portions as described above in connection with thecorner construction elements 202. An additional facing layer may be provided on the inside surface 2032. Like thecorner constructions elements 202, thecorner constructions element 204 may be formed of foam material or solid polymer material, or any other suitable material, and/or may have hollow sections and webs, and/or may omit the fastener-engagingelements 2022. - The
inside surface 2042 of thecorner construction element 204 in this embodiment is a single flat surface. -
FIG. 32 is a plan view of an assembled wall structure including acorner construction element 204′.

An additional facing layer may be provided on theinside surface 2042″. -
FIG. 34 is a plan view of an assembled wall structure including acorner construction element 205. Thecorner construction element 205 may have any desired radius, e.g., ranging from about 6 inches to about 30 feet, and may have facinglayers 2056 on the inside and outside curved surfaces (corner-forming surfaces, which are not separately labeled in this embodiment) of thebody 2050, which may be, e.g., of foam material or solid polymer material as described above. As with thecorner construction elements 202 described above,studs 104 are connected to thecorner construction element 206 by passingfasteners 108 through thestuds 104 and into fastener-engagingelements 2022. Although not depicted inFIG. 23 , thecorner construction element 205 may have wing portions as described above in connection with thecorner construction elements 202, extending from the outside curved surface and/or the inside curved surface, or theinside facing layer 2066 and/or theoutside facing layer 2066.

Thewebs 2060 may be provided in any desired number and/or configuration. For example, rather than defining approximately squarehollow sections 2062 as shown, thewebs 2060 may be in a repeating “W” configuration that defines approximately triangularhollow sections 2062. As described above, such a “W” configuration that defines approximately triangular hollow sections can provide a strength advantage, and/or an acoustic advantage (e.g., tapping on a construction element with such a “W” configuration may not produce as much of a “hollow” or “drum” sound as tapping on a construction element with square hollow sections). Additionally, as also described above, thewebs 2060 may have different thicknesses, and the thickness may be determined according to one or more of various factors. -
FIG. 36 is a plan view of an assembled wall structure including acorner construction element 207. Thecorner construction element 207 comprisesstuds 104′, to which are attachedcurved wall elements end-most studs 104′ are “fastener strips” in this embodiment. Thecurved wall elements curved wall elements curved wall elements studs 104′ by any suitable fasteners such as staples, nails, screws, tape or adhesive. - The
studs 104′ may be of wood, metal, fiberglass, carbon-fiber material, plastic material such as PVC or vinyl, or a composite of any such materials. As depicted, thestuds 104′ may have a different width, such as a greater width, than thestuds 104 to compensate for thecurved wall elements wall panels - Although the corner construction elements 205-207 are shown with a relatively large radius, the may have an internal radius as small as about 2 inches. A typical maximum radius may be up to about several feet, or up to 10 feet or even up to about 30 feet or more. The radius may, for example, be any radius from 2 inches to 30 feet, in increments of ⅛″. Additionally, although the corner construction elements 205-206 are shown with facing
layers - Although not depicted in
FIGS. 34-36 , the corner construction elements 205-207 may have wing portions as described above in connection with thecorner construction elements 202, on the outside surface and/or the inside surface. -
FIG. 37 is a perspective view of thecorner construction element 207. Atop plate 1042 and abottom plate 1044 are attached to ends of thestuds 104′. In this figure, thecurved wall elements studs 104′, thetop plate 1042 and thebottom plate 1044 may be of wood, metal, fiberglass, carbon-fiber material, plastic material such as PVC or vinyl, or a composite of any such materials. In some embodiments, thetop plate 1042 and thebottom plate 1044 may be cut from plywood, possibly being formed of two or more layers of plywood for greater strength and stability. - Although the
corner construction element 207 is shown to match walls oriented at 90° relative to each other, it may be altered to match walls oriented at any other angle relative to each other. - All of the corner construction elements and the end cap construction elements may exist as fully formed elements prior to attachment to wall structures such as stud wall frames.
- Those skilled in the constructions arts will appreciate that various ones of the features described above in the different embodiments can be combined with each other. For example, although not explicitly depicted for each embodiment, any of the above-described construction elements may include
recesses 2028 as described above in connection with various embodiments and/or may include a facinglayer 2026 as described above in connection with various embodiments, and/or may includewing portions 2029 as described above in connection with various embodiments. - Additionally, although multiple-section corner construction elements have been described with two sections in various embodiments above, it will be appreciated that corner construction elements with three or more sections are also possible.
- Although the drawings depict wall structures having vertically extending studs, the construction elements may also be installed in other orientations. For example, a corner construction element according to any of the above-described embodiments may be installed where an overhead ceiling surface meets a vertical or slanted surface, such as in a stairwell. As another example, an end cap construction element according to any of the above-described embodiments may be installed on the overhead surface of a doorway or window opening.
- While the invention has been described in conjunction with the specific embodiments described above, these embodiments should be viewed as illustrative and not limiting. Various changes, substitutes, improvements or the like are possible within the spirit and scope of the invention.
- For example, although fastener-engaging
elements 2022 and/orfasteners 108 are provided in some embodiments described above for attaching the construction elements tostuds 104, in other embodiments the construction elements may be attached tostuds 104 by construction adhesive or the like. - As another example, in addition to or instead of providing the construction elements in multiple sections that assemble vertically end to end as described in some embodiments above, the construction elements may be provided in multiple sections that assemble horizontally side to side. This can be particularly advantage in the context of construction elements having a relatively large radius, such as those shown in
FIGS. 34 and 35 , for example if the radius is two feet or more (but not limited to this case). The horizontally assembled elements may be attached together using one or more of the structures and/or methods described above, such as adhesive, keys engaged in slots, screws or nails installed in a “toenail” configuration, corrugated nails, dowels or other protrusions on one section that insert into corresponding recesses of another section, or the like.
