The invention relates to the art of framing jigs.
The light frame construction of wall, roof or floor structures must be completed in accordance with local Building Codes. These Codes outline the requirements for construction of these structures including acceptable materials, material sizes and the configuration of the framed structures. Typical vertical wall framing practice is to mechanically fasten a series of vertical framing elements (studs) to upper and lower horizontal framing elements (header plates and sills). The studs are oriented perpendicularly to the header plates and sills and are typically spaced such that the distance between the centers of adjacent studs does not exceed 16 inches. Some framing applications require the stud spacing to be as small as 12 inches while other less stressed framing applications may permit the inter-stud spacing to increase to 24 inches.
Traditional framing techniques are based on the layout and marking of the sill and header plates with a tape measure and pencil to identify the correct stud attachment positions. The studs are then held in the correct position by the fabricator, oriented approximately perpendicularly to the sill or header plate and then mechanically fastened in place with either nails or screws. The perpendicular orientation of the studs relative to the sill or header plate is typically confirmed using a framing square. It can be difficult to hold the stud in the correct location and at the correct orientation while mechanically fastening the stud to the sill or header plate without the assistance of a helper, particularly for persons who do not do this for a living. It should be noted that the construction of framing elements can be completed either as a separate module to be installed in the structure as a single element (horizontal framing) or they can be constructed in place during the fabrication of the building (vertical framing). In either case, the studs are typically located, oriented and fastened in place according to the above described process with similar challenges associated with the correct positioning and orientation of the studs relative to the sill and header plates. In addition, framing elements fabricated in place require the use of a fastening technique called toe-nailing wherein the fabricator attaches the studs to the plates by driving the fasteners at an angle through the studs and into the sill and header plates since it is impossible to fasten through the plates into the studs once the plates have been installed.
During the construction of wall elements, it may be desirable to include openings in the framing for windows and doors. These elements also require the accurate layout, location and orientation of framing elements.
There are numerous framing aids that have been developed that focus on the accurate spacing of studs. U.S. Pat. No. 5,490,334 to Payne (1996) discloses a tool that spaces the studs the correct distance but does not address the need to hold the stud perpendicular to either the sill or the header plate.
U.S. Patent Application Publication US 2008/0006976 A1 by Riley addresses the need to brace the studs during fastening but describes the use of two small flanges on either side of the stud openings to provide this functionality. This method cannot be relied upon to accurately orient a stud the length of which is approximately 200 times the height of these flanges. This tool is not suitable for framing elements that are less than 3½″ in depth and requires the use of temporary fasters to positively locate the tool to the sill or header plate since the tool does not positively engage the framing elements on its own. In addition, this tool would be very cumbersome to use based on its length and utilizes spacers to position the studs at various spacings that could result in errors if used incorrectly by an unskilled worker.
A stud spacing and orientation jig disclosed in U.S. Pat. No. 2,567,586 to Werder (1951) uses an angle iron with positioning lugs to orient the timbers in the desired attitude. The angle iron does not allow the jig to laterally retain the timbers on its own without the use of tacking nails since the jig does not enclose the sill on each side. The installation and removal of these tacking nails would increase the time required to complete the framing task. In addition, the use of the solid positioning lugs dictates that the fabricator must end nail the studs to the sill or header plates as there would be no access to toenail the studs to the sill or header plate.
Thus, there remains a need for a tool that can be used by a single person, which is especially suited for the home handyman or so-called ‘do it yourselfer’, to accurately position, orient and retain framing elements during construction.
According to one aspect of the invention a framing aid is provided having a central web; at least first and second stud saddles connected to the web. The first stud saddle has a first longitudinal axis and the second stud saddle has a second longitudinal axis. The first and second longitudinal axes are substantially parallel to one another. At least one sill saddle is connected to the web, the sill saddle having a third longitudinal axis that is substantially perpendicular to the first and second longitudinal axes of the stud saddles. The sill saddle is spaced apart and not immediately adjacent to the first and second stud saddles so as to provide a first opening between the sill saddle and the first stud saddle and a second opening between the sill saddle and the second stud saddle. These openings provide access points to allow a fabricator to toenail studs thereat.
The connection of saddles to the central web is achieved by integrally forming the web with the saddles, for example in a molding process, or by mechanically connecting the web with the saddles.
The central web preferably includes a planar substrate having a first side and a second side substantially perpendicular to the first side. The first stud saddle is disposed adjacent to the first side of the substrate and the sill saddle is disposed adjacent the second side of the substrate.
At least one of the first and second stud saddles may be provided a two-sided body having first and second sidewalls, the first sidewall being connected and generally orthogonal to the substrate and the second sidewall being connected to the first sidewall and generally parallel with the substrate.
Alternatively, the first and second stud saddles may be provided as a three-sided body having first, second and third sidewalls, the first sidewall being connected to and generally orthogonal to the substrate, the second sidewall being connected to the first sidewall and generally parallel with the substrate, and the third sidewall being connected to the second sidewall and generally orthogonal to the substrate, wherein the spacing between the first and third sidewalls substantially defines the maximum depth of a framing stud accommodated in the saddle.
Likewise, the sill saddle maybe provided as a two-sided body having first and second sidewalls, the first sidewall being connected and generally orthogonal to the substrate and the second sidewall being connected to and generally parallel with the substrate. Alternatively, the sill saddle may be provided as a three-sided body having first, second and third sidewalls, the first sidewall being connected and generally orthogonal to the substrate, the second sidewall being connected to the first sidewall and generally parallel with the substrate, and the third sidewall being connected to the second sidewall, wherein the spacing between the first and third saddle sides substantially defines the maximum depth of a stud accommodated in the saddle. More preferably, however, the sill saddle further includes a two-sided sill body connected to the three-sided body, the two-sided body comprising the third wall of the three-sided body and a fourth wall connected to and parallel with the second wall of the three-sided body.
The planar substrate may include at least one aperture formed therein having a flange at the periphery of the aperture for stiffening the substrate.
In addition, a stiffening flange may substantially circumscribe the planar substrate, the flange being orientated substantially orthogonal to the substrate. If provided, the flange may define a portion of each of the saddles.
According to another aspect of the invention a framing aid is provided which includes a central web including a planar substrate; first and second stud saddles connected to the web, the first stud saddle having a first longitudinal axis and the second stud saddle having a second longitudinal axis, the first and second longitudinal axes being substantially parallel to one another, wherein each of the first and second stud saddles is a three-sided body having a first sidewall connected to and generally orthogonal to the substrate, a second sidewall connected to the first sidewall and generally parallel with the substrate, and a third sidewall connected to the second sidewall and generally orthogonal to the substrate; and a sill saddle connected to the web, the sill saddle having a third longitudinal axis that is substantially perpendicular to the first and second longitudinal axes of the stud saddles, the sill saddle comprising a three-sided body connected to a two-sided body, the three sided body having a first sidewall connected and generally orthogonal to the substrate, a second sidewall connected to the first sidewall and generally parallel with the substrate, and a third sidewall connected to the second sidewall, the two-sided body comprising the third wall of the three-sided body and a fourth wall connected to and parallel with the second wall of the three-sided body.
Preferably, the sill saddle is spaced apart and not immediately adjacent to the first and second stud saddles so as to provide a first opening between the sill saddle and the first stud saddle and a second opening between the sill saddle and the second stud saddle, the openings each being adequately sized for toe nailing studs.
The framing aid according to this aspect of the invention may also include a flange substantially circumscribing the planar substrate, the flange being orientated substantially orthogonal to the substrate in order to stiffen it. The flange may define a portion of each of the saddles.
According to another aspect of the invention a framing aid is provided which includes a central planar web; at least three stud-gripping saddles connected to the central planar web, wherein each saddle has a longitudinal axis and at least two of the saddles have longitudinal axes parallel to each other and the longitudinal axis of at least one saddle is perpendicular to the at least two parallel saddles; and a flange that extends from the at least one perpendicular saddle and is parallel to the central planar web.
The foregoing and other aspects of the invention will be better understood with reference to the drawings, wherein:
In the particular embodiment shown in
Each stud saddle 104A or 104B is preferably provisioned as a three-sided body to support three faces of a rectangular cross-sectioned framing member as will be seen for example in
The sill saddle 106 is also preferably provisioned with a three-sided body. In addition, the preferred sill saddle 106 includes an additional outwardly extending flange 120 that is orientated in parallel to the planar substrate 102. This flange 120, when coupled with the three-sided body, provides in effect a complimentary two-sided saddle. More particularly, the three-sided body of the sill saddle 106 is provided by a first sidewall 122 that is connected to and generally orthogonal to the planar substrate 102, a second sidewall 124 that is connected to the first sidewall 122 and generally parallel with the planar substrate 102, and a third sidewall 126 connected to the second sidewall 124 and generally orthogonal to the planar substrate 102. The two-sided body of the sill saddle 106 is provided by the third sidewall 126 of the three-sided body and the flange 120, which is parallel to the second sidewall 124. The flange 120 is preferably formed through the preferred molding process as a seamless continuation of the second sidewall 124, but may be considered functionally as a fourth sidewall 128 connected to the second and third sidewalls 124, 126. The three-sided body of saddle 106 is useful in circumstances where the underside of the header plate or sill can be easily accessed and is of standard depth, and the two-sided body of saddle 106 is useful in circumstance where the underside of the header plate or sill cannot be easily accessed and/or is not of standard depth, as discussed in greater detail below.
The stud saddles 104 are preferably positioned at a predetermined spacing S apart to facilitate the positioning of framing studs at an industry standard spacing, such as 16 inches, center-to-center, or other standard spacing as the case may be depending on the application at hand.
The spacing D1 between the first and third sidewalls 112, 116 substantially defines the maximum width of a framing member that can be accommodated in the stud saddle 104. Likewise, the spacing D2 between the first and third sidewalls 122, 126 substantially defines the maximum width of a framing member that can be accommodated in the sill saddle 106. For use with conventional wood framing studs, D1 and D2 are preferably about 1.5 inches, which is the standard width for the nominal 2×4 or 2×6 wood framing studs widely commercially available.
The jig 100 is also characterized by open space between the stud saddles 104 and the sill saddle 106, as the sill saddle 106 is spaced apart from and not immediately adjacent to the first and second stud saddles 104A, 104B leaving a open corner 132A between the sill saddle 106 and stud saddle 104A and a open corner 132B between the sill saddle 106 and the second stud saddle 104B. The open corners 132A, 132B are preferably sized to allow adequate room for toe nailing and/or screwing studs and the like.
In the illustrated embodiment the jig 100 includes a circumferential flange 130 that fully surrounds the planar substrate 102. The flange 130, which is preferably integrally formed with the substrate 102, is oriented orthogonal to the substrate and provides or defines the first sidewalls 112, 122 of the stud and sill saddles 104, 106. The circumferential flange 130 increases the strength and stiffness of the jig 100, although it will be appreciated that the circumferential flange 130 is not essential and if provided need not fully surround the planar substrate 102. If desired, the jig 100 can also include stiffening ribs 134 distributed around the both sides of the intersection between the planar substrate 102 and the circumferential flange 130 to increase the strength and stiffness of the jig 100. Additionally or alternatively, the planar substrate 102 may have one or more hand hold apertures 136 therein to facilitate installation and removal of the jig from the framing members, and these apertures 126 may incorporate a flange or ring 138 around the edges thereof to reduce flex in the planar substrate.
Once the studs 140 are secured, the fabricator can then reposition the jig 100 so that one stud saddle engages the previously fastened first interior stud 140A and the sill 142 as shown in
Once the studs 140 are secured, the fabricator can then reposition the jig 100 so that one stud saddle 142A engages the previously fastened first interior stud 140A and the outside orthogonal edge or third sidewall 126 of the sill saddle 106 engages the horizontal surface 142T of the sill whilst the flange 120 abuts the adjacent vertical surface of the sill 142 as shown in
It should be noted that the open corners 132A, 132B of the jig 100 allow toe nailing from the front face or side face(s) of the studs. At the same time, it will be appreciated that the open corners force the stud saddles 104 to be raised in elevation in comparison to the elevational position of the sill saddle 106. As shown in
Likewise, it will be appreciated that in other alternative embodiments the third sidewall 116 on one or both the stud saddles 104A, 104B may be omitted, but this will have an effect on the effectiveness of the jig to hold the framing stud in place for nailing and the like.
The above-described embodiments of the invention are intended to be examples of the invention and alterations and modifications may be effected thereto, by those of skill in the art, without departing from the spirit of the invention.
