1. Technical Field
This disclosure generally relates to frame members or studs and in particular to reinforcement of frame members or studs.
2. Description of the Related Art
Frame members such as studs are used in construction, mechanical framing and other applications. Studs, and more generally frame members, are used for structural reinforcement and often bear a mechanical load in applications. Studs and frame members may also be used to provide a mechanical framing and may bear or support other elements of a structure.
A light-weight metal stud is described in U.S. patent application Ser. No. 13/767,764, filed Feb. 14, 2013. Metal studs offer a number of advantages over traditional building materials, such as wood. For instance, metal studs can be manufactured to have strict dimensional tolerances, which increase consistency and accuracy during construction of a structure. Moreover, metal studs provide dramatically improved design flexibility due to the variety of available sizes and thicknesses and variations of metal materials that can be used. Moreover, metal studs have an inherent strength-to-weight ratio which allows them to span longer distances and better resist forces such as bending moments.
This disclosure generally describes inserts for use with studs, for example metal studs, as well as kits and methods associated with such inserts. The stud may include a pair of elongated channel members opposed to one another across a width of the stud, each of the channel members having a major face, a first flange and a second flange, the first and the second flanges extending from the major face and the second flange opposed to the first flange across a thickness of the stud.
Framing members, for example framing members used to construct frame structures, may buckle or deform under strain or loads. Buckling or deformation of framing members due to physical strain or load(s) is referred to as web buckling or web crippling. Web buckling or crippling is more likely to occur in frame members without a solid or continuous web. Typically, or normally, this failure occurs at the ends of individual framing members. An insert member in the form of a block may reduce or eliminate any tendency of a stud to buckle under load.
An insert for use with the stud may be summarized as including a block of material having a first end, a second end, a first major face, a second major face, a first side and a second side, the second end opposed across a length of the insert from the first end, the second major face opposed across a thickness of the insert from the first major face, and the second side opposed across a width of the insert from the first side, the first and the second sides spaced from one another to provide at least an interference fit between the major faces of the pair of elongated channel members of the stud when received therebetween over at least a majority of the length of the insert. The first and the second major faces of the block may be spaced from one another to provide at least a friction or an interference fit between the pairs of flanges of the pair of elongated channel members of the stud when the insert is received therebetween over at least a majority of the length of the insert.
The first and the second sides of the block may be parallel to one another over at least a majority of the length of the insert and the first major face and the second major face may be parallel to one another over at least a majority of the length of the insert. The block may be tapered proximate the first end across at least one of the width or the thickness of the insert. The block may include at least one outwardly extending stop flange proximate the second end of the insert, the stop flange sized and dimensioned to physically engage an end of the stud when the insert is received therein. The stop flange may extend outwardly from the first and the second major faces proximate the second end of the insert. The block may be tapered proximate the first end across both the width or the thickness of the insert.
The first and the second sides may each have a recess formed along at least a portion of the length of the insert, for example to accommodate protruding fasteners received by the stud.
The block may include a number of apertures. For example the block may include a number of apertures that extend across the thickness of the insert passing through the first and the second major faces.
The block of material may be selected from the group consisting of metals and polymers.
An insert for use with the stud may be summarized as including a trapezoidal prism having a first end, a second end, a first major face, a second major face, a first side and a second side, the second end opposed across a length of the insert from the first end, the second major face parallel to and opposed across a thickness of the insert from the first major face, and the second side parallel to and opposed across a width of the insert from the first side, the first and the second sides spaced from one another to provide at least an interference fit between the major faces of the pair of elongated channel members of the stud when received therebetween over at least a majority of the length of the insert and the first and the second major faces of the block are spaced from one another to provide at least a friction or an interference fit between the pairs of flanges of the pair of elongated channel members of the stud when the insert is received therebetween over at least a majority of the length of the insert.
The block may be tapered proximate the first end across the width or the thickness of the insert. The block may include at least one stop flange that extends outwardly from the first and the second major faces proximate the second end of the insert, the stop flange sized and dimensioned to physically engage an end of the stud when the insert is received therein.
The first and the second sides may each have a recess formed along at least a portion of the length of the insert. The block may include a number of apertures that extend across the thickness of the insert passing through the first and the second major faces.
The block of material may be selected from the group consisting of metals and polymers.
A method of forming an insert for use with a stud may be summarized as including providing a solid block of thick gauge material, the thick gauge being at least 3 times a gauge of material that forms the elongated channel members; providing at least one manufacturing operation on the solid block of material to produce a trapezoidal prism having a first end, a second end, a first major face, a second major face, a first side and a second side, the second end opposed across a length of the insert from the first end, the second major face parallel to and opposed across a thickness of the insert from the first major face, and the second side parallel to and opposed across a width of the insert from the first side, the first and the second sides spaced from one another to provide at least an interference fit between the major faces of the pair of elongated channel members of the stud when received therebetween over at least a majority of the length of the insert and the first and the second major faces of the block are spaced from one another to provide at least an interference fit between the pairs of flanges of the pair of elongated channel members of the stud when the insert is received therebetween over at least a majority of the length of the insert.
The method may further include producing a tapered dimension proximate the first end across at least one of the width or the thickness of the insert; and forming at least one stop flange that extends outwardly from the first and the second major faces proximate the second end of the insert, the stop flange sized and dimensioned to physically engage an end of the stud when the insert is received therein.
The method may further include forming at least one respective recess in the first and the second sides along at least a portion of the length of the insert; and forming a number of apertures that extend across the thickness of the insert and which pass through the first and the second major faces.

Manufactured framing members, for example metal framing members, are used to construct frame structures. U.S. patent application Ser. No. 13/767,764, entitled LIGHT-WEIGHT METAL STUD AND METHOD OF MANUFACTURE, provides an example of a manufactured framing member in the form of a metal stud.
Manufactured framing members may comprise sheet metal, and optionally a wire web connecting two elongated channels. It is economically advantageous to minimize the amount of material in a manufactured framing member, for example by using relative high or light weight gauge sheet metal to form the elongated channels. However, use of thin gauge material may result in the framing member buckling or deforming under strain or loads. Buckling or deforming of framing members due to physical strain or load(s) is referred to as web buckling or web crippling. Web buckling or crippling is more likely to occur in frame members without a solid or continuous web. Typically, or normally, this failure occurs at the ends of individual framing members. In one example of load bearing metal frame members, vertical studs installed in walls may buckle at or proximate a bottom end thereof.
As described herein, reinforcement inserts may strengthen framing members, mitigating web buckling or crippling. The reinforcing insert is inserted at least partially into a framing member to strengthen or reinforce the framing member.
The stud 100 comprises a pair of elongated channel members 110a, 110b opposed to one another across a width W100 of stud 100. A first one of the channel members 110a has a major face 112a, first flange 114a and second flange 116a. The first and second flanges 114a, 116a extend from the major face 112a of the first channel member 110a. The first and second flanges 114a, 116a oppose each other across a thickness T100 of the stud 100.
Similarly, a second one of the channel members 110b has a major face 112b (obscured in
The stud 100 further comprises a web 120. The web 120 couples the elongated channel members 110a, 110b to each other in opposition across a width W100 of the stud 100 such that the major faces 112a, 112b are parallel to each other. For example, the web 120 may be a wire truss physically connecting the elongated channel members 110a, 110b to each other such that the elongated channel members 110a, 110b are in opposition with the major faces 112a, 112b parallel to each other.
A framing member, such as stud 100 which has a discontinuous or nonsolid web physically coupling its constituent elongated channel members, is susceptible to failure such as web buckling as discussed above. For example, the elongated channel members 110a, 110b may be manufactured from light gauge metal, for example a light gauge aluminum. These elongated channel members 110a, 110b may be coupled by one or more wire configurations to form a stud. When under a substantial load or other stress, a framing member with a wire truss web configuration as shown in
As illustrated in
The width may be sized or dimensioned to provide at least a friction or interference fit between the major faces of the pair of elongated channel members of the stud when received therebetween over at least a majority of the length of the insert. The thickness may be sized or dimensioned to provide at least a friction or interference fit between the pairs of flanges of the pair of elongated channel members of the stud when the insert is received therebetween over at least a majority of the length of the insert.
The reinforcing insert 140 is at least partially inserted or received into a space between the pair of opposed elongated channel members 110a, 110b of the stud 100. The reinforcing insert 140 is inserted into one end, or respective reinforcing inserts 140 are inserted into each end of the stud 100. The reinforcing insert 140 fits snugly in an interior space, between the first and second flanges 114a, 116a; and fits snugly between the first and second flanges 114b, 116b. In this way, the reinforcing insert 140 reinforces the channel members, maintaining the two flanges of an elongated channel member in position when the framing member is under load or compression, thereby increasing relative failure strength. That is, the reinforcing insert 140 strengthens the structural integrity of stud 100 to prevent or minimize web buckling or crippling.
As illustrated in
The reinforcing insert 140 may be formed, for example, by machining, casting, extruding or other industrial manufacturing process(es) from steel, aluminum, brass, bronze or other suitable metal or metallic alloy. For example, reinforcing insert 140 may result from machining of a block of aluminum alloy which is then anodized. Also, for example, the insert 200 may result from machining stainless steel or a steel which is subsequently galvanized for corrosion protection. The reinforcing insert 140 could also be made of, for example, a rigid polymer such as PVC, ABS, fiberglass, open or closed cell rigid foams, or other plastic material. The material used to make reinforcing insert 140 might advantageously have a compressive strength in the range of 8000 to 12000 psi.
More specifically, the first major face 230 is spaced from the second major face 240 (by thickness T200) to provide at least a friction or an interference fit between the pairs of flanges of the pair of elongated channel members of the stud 100 when the reinforcing insert 200 is received therebetween, over at least a majority of the length L of the reinforcing insert 200. The first side 250 is generally or substantially parallel to the second side 260 over at least a majority of the length L200 of reinforcing insert 200. Similarly, the first major face 230 is generally or substantially parallel to the second major face 240 over at least a majority of the length L200 of the reinforcing insert 200.
In contrast to the embodiment of
The reinforcing insert 200 may have a tapered portion 215 at least proximate the first end 210. For example, the tapered portion 215 may be tapered across at least one of the width W200 and/or the thickness T200 of the reinforcing insert 200. The tapered portion 215 proximate the first end 210 facilitates insertion of reinforcing insert 200 into a framing member such as stud 100.
The tapered portion 215 of the reinforcing insert 200 is visible in
As further shown in
Of course, the tapered portion 215 at the first or inserting end 210 of the reinforcing insert 200 facilitates insertion of the reinforcing insert 200 into an end of a stud or other framing member. Therefore, the dimensions of the tapered portion 215 and whether both the width and thickness are tapered will depend upon the particular application and physical dimensions of the stud to be reinforced. That is, whether the taper will be applied to both the width and thickness of the insert, or to just one dimension, will depend upon the individual application of the reinforcing insert 200. Thus, the reinforcing insert 200 may be viewed as a trapezoidal prism defined by a first end, a second end, a first major face, a second major face, a first side and a second side.
The reinforcing insert 200 may further include at least one outwardly extending stop flange 225 proximate the second end 220. The stop flange(s) 225 is sized and dimensioned to physically engage an end of a stud when the reinforcing insert 200 is received therein. The stop flange(s) 225 prevents the reinforcing insert 200 from sliding into the stud 100. The stop flanges 225 extend peripherally outwardly from first and second major faces 230, 240 proximate second end 220. As shown in
The stop flange(s) 225 illustrated in
In some implementations, the reinforcing insert 200 may be paired with a wall stud or other framing member likely to receive nails, screws or other invasive fasteners. The reinforcing insert 200 may include one or more recesses 255, 265, as shown in
The reinforcing insert 200 may be formed by machining a solid block of material. The reinforcing insert 200 may include one or more aperture(s) 205. Aperture(s) 205 may lighten the reinforcing insert 200 and/or reduce the amount of material needed for the reinforcing insert 200. As shown in
The reinforcing insert 200 may be formed, for example, by machining, casting, extruding or other industrial manufacturing process(es) from steel, aluminum, brass, bronze or other suitable metal or metallic alloy. For example, reinforcing insert 200 may result from machining of a block of aluminum alloy which is then anodized. Also, for example, the insert 200 may result from machining stainless steel or a steel which is subsequently galvanized for corrosion protection. The reinforcing insert 200 could also be made of, for example, a rigid polymer such as PVC, ABS, fiberglass, open or closed cell rigid foams, or other plastic material. The material used to make reinforcing insert 200 might advantageously have a compressive strength in the range of 8000 to 12000 psi.
When the web of the stud is a type of wire webbing, the length of the insert must be coordinated with the pitch of the wire truss forming the webbing and the number of wires in the truss. In the context of a single wire truss, the length of the reinforcing insert may optimally be approximately one pitch in length. Thus, the insert would reinforce the wire webbing over one pitch of the wire truss of the stud when inserted. In the context of a double wire truss, the length of the reinforcing insert may optimally be approximately a half pitch in length. Thus, the reinforcing insert would reinforce the wire webbing over half the pitch of the wire truss of the stud when inserted. Returning to
Therefore, depending upon the application, and particularly in the context of studs with wire-type webbings, it may be desirable to have kits with one or more reinforcing inserts sized to provide a desired reinforcement of the stud, and optionally one or more studs. Thus, for example, in the context of a stud with a single wire truss webbing, a corresponding reinforcing insert could be provided in a stud kit, the corresponding insert having a length reinforcing approximately one pitch of the wire webbing when the insert is inserted into the stud. Similarly, in the context of a stud with a double wire truss webbing, a corresponding insert could be provided in a stud kit, the corresponding insert having a length reinforcing approximately a half pitch of the wire webbing when the insert is inserted into the stud.
