## Background
BACKGROUND
The present disclosure relates generally to joist subframing systems. In particular, joist subframing systems including horizontally arranged elongate frame members (i.e., joist members) each being adjustably attached to vertically arranged support members are shown and described.
Joist subframing systems include horizontal supporting members that run between foundations, walls, and/or beams to support an overlying structure (e.g., an exterior deck, an interior floor, etc.). Known joist subframing systems are not entirely satisfactory for the range of applications in which they are employed. For example, existing joist frames are comprised of wood joist beams that can have a high weight and profile of the joist frame, and are subject to decay, rot, and/or insect infestation. In an additional example, conventional joist subframes cannot be easily adjusted for a desired height of a surface and/or to create a level surface (e.g., floor) over an uneven and/or angled underlying surface. In even another example, some joist systems cannot be used in combination with underlying waterproofing systems and/or can tear/puncture an underlying waterproofing system. In this example, water may collect under the joist subframe and cause damage to a foundation and/or other adjacent structures.
Thus, there exists a need for joist subframing systems and methods that improve upon and advance the design of known joist subframing systems. Examples of new and useful joist subframing systems relevant to the needs existing in the field are discussed below.
Disclosure addressing one or more of the identified existing needs is provided in the detailed description below. Examples of references relevant to joist subframing systems include U.S. Patent References: U.S. Pat. No. 6,332,292 and U.S. Pat. No. 8,256,175. The complete disclosures of the above patents and patent applications are herein incorporated by reference for all purposes.
SUMMARY

Throughout the following detailed description, examples of various joist subframing systems and methods are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
With reference to FIGS. 1-12, a first example of a joist subframing system, joist system 100 will now be described. Joist system 100 includes elongate frame members 102, support members 104, foot members 106, and fastening members 108. Joist system 100 is disposed between an underlying surface 110 (e.g., a ground surface, a foundation surface, etc.) and an overlying surface members 112. Elongate frame members 102 are metallic frame members (e.g., aluminum elongate frame members) that include attachment mechanisms for support members and the height of the elongate member on the support member can be selectively adjusted. Accordingly, joist system 100 functions to support an overlying floor surface. Additionally or alternatively, joist system 100 can be used to support a ceiling and/or roof surface.
Joist system 100 addresses many of the issues and problems that occur with conventional joist subframes. For example, the elongate frame members are comprised of a metallic material that is not subject to insects, rot, and decay. In another example, as attachment mechanisms are built into the elongate frame members, joist subframe system 100 has an overall lower profile and heights of the elongate frame members are easily adjusted and/or leveled to create a level overlying surface. In even another example, joist subframe system 100 can be used in combination with multiple types of underlying water proofing layers.
As can be seen in FIGS. 1-3, each, of elongate frame members 102 are horizontally arranged. Further, most of elongate frame members 102 are generally parallel and equally spaced relative to adjacent elongate frame members. It will be appreciated that joist subframe system 100 can be used to create a desired configuration for a floor. FIG. 3 shows one example arrangement/configuration 130 for a joist subframe.
In the example of FIG. 3, elongate frame members 102a-102h are parallel to each other and elongate frame members 102i-102l are parallel to each other, while elongate member 102m is disposed at an angle relative to elongate frame members 102a-102h and elongate member 102n is disposed at an angle relative to elongate frame members 102i-102l. Further, some elongate frame members (e.g., 102e and 102i, 102f and 102j, 102g and 102k, 102h and 102l, 102m and 102n) are in a linear configuration, and are substantially continuous in arrangement/configuration 130. Parallel elongate frame members (102a-102h and 102i-102l) and elongate frame members disposed at an angle relative to parallel elongate frame members (102m and 102n) are joined by horizontally arranged fastening members 108.
As depicted in FIG. 4, fastening members 108 are inserted through holes 146 in each of elongate frame members 102. A first end of each fastening member 108 is attached to one elongate frame member 102 and a second end of the fastening member 108 is attached to an adjacent elongate frame member 102. A position of each of fastening members 108 is releasably fixed by coupling and/or attachment of a securing member 148 to the fastening member on each of a first side and a second side of an associated elongate frame member 108. Fastening members 108 are attached to vertical walls of the elongate frame members.
In the present example, fastening members 108 are threaded members and securing members 148 are nuts that are complimentarily configured to the threaded members. Further, a washer can be disposed between securing member 148 and a wall of the elongate frame member. In one specific example, the fastening members, the nuts, and the washers are 3⁄8′′ stainless steel. In alternate examples, one or more of the fastening members and the securing members can have a different configuration. In one specific alternate example, the fastening members can be non-threaded members and the securing members can be releasable clamping members.
Returning to FIG. 3, in some examples only one fastening member 108 is used to join adjacent elongate frame members (e.g., elongate frame members 102i-102l). In other examples, two fastening members 108 are used to join adjacent fastening members (e.g., elongate frame members 102a-102h). It will be appreciated that more or fewer fastening members can be used to attach adjacent elongate frame members. It will be further appreciated that fastening member can be of equal length to accommodate elongate frame members that are parallel relative to adjacent elongate frame members (e.g., fastening members 108 attached between elongate frame members 102a-102d) and/or fastening members can be of different lengths to accommodate elongate frame members disposed at an angle relative to adjacent elongate frame members (e.g., fastening members attached between elongate frame members 102h and 102m).
As depicted in FIG. 3, joist system 100 further includes capping members 132 (e.g., 132a-132f). Capping members can be square tubes comprised of a metallic material, such as aluminum or steel. Capping members can be any desired length that is necessary to “cap” an ends of elongate frame members 102 and are generally perpendicular relative to the elongate frame members. In one specific example, capping members are 25′×11⁄4′′×11⁄4′′ aluminum square members that can be cut to a desired length using a blade, such as a carbide blade.
In the present example configuration, capping member 132a is a longer capping member that caps a first end of elongate frame members 102a-102h and 102m, capping member 132b is a shorter capping member that caps a second opposing end of elongate frame members 102a-102d and capping members 132c and 132d are even shorter capping members that cap a second opposing end of elongate frame members 102e and 102f, and 102g and 102h, respectively.
Capping members 132e and 132f are of a substantially equal length relative to capping members 132c and 132d. Capping member 132e caps a first end of elongate frame members 102i and 102j, while capping member 132f caps a first end of elongate members 102k and 102l. A second opposing end of elongate frame members 102i-102l and 102n are capped by a capping member 132g, which is of a substantially equal length relative to capping member 132b. Longitudinal faces of capping members 132c and 132e, and 132d and 132f can be attached via attachment members and/or an adhesive (not specifically shown).
In alternate examples, a single capping member can be used to cap a second end of an elongate frame member and a first end of a linearly aligned other elongate frame member. In other words, capping member 132c could be a capping member for second ends of elongate frame members 102e and 102f and first ends of elongate frame members 102i and 102j. In even other alternate examples, capping members can be excluded from joist system 100.
Turning attention to FIGS. 5 and 6, in the present example, die elongate frame members are each “C” channel elongate frame members comprised of a metallic material. In one specific example, the “C” channel elongate frame members are 25′×11⁄4′′×2′′ aluminum joists. The elongate frame members can be cut to a desired length using a blade, such as a carbide blade.
As shown in FIG. 5, in a first example orientation 134, the “C” channel elongate frame members are oriented so that an open side 114 is faced downward (i.e., faced toward an underlying ground surface). Accordingly, in the configuration shown in FIG. 5, each elongate frame member 102 includes a central wall 116 with two side walls 118 (i.e., 118a and 118b) extended downwardly from opposing ends of central wall 116. In this example, central wall 116 is a horizontal central top wall and side walls 118 are vertical side walls. As described above in reference to FIG. 4, fastening member 108 is inserted through holes 146 (i.e., holes 146a and 146b) in the side walls 118 (i.e., side walls 118a and 118b, respectively) of elongate frame member 102.
Central wall 116 includes receiving holes 120 for coupling elongate frame members 102 to support members 104. As shown in FIG. 5, support members 104 are threaded members configured to be inserted through holes 120. Therefore, the through holes are a support member attachment mechanism configured to couple one of the support members to the elongate body of the elongate frame members. Each of adjustable height securing members 122 are positionally adjustable and coupled to one of support members 104 in order to releasably fix a position of the support member and the elongate frame member. In other words, the adjustable height securing members are selectively tightenable and loosenable to one of the support members to releasably fix a height of coupling of the elongate frame member to the support member.
In the present example, securing members 122 are nuts that are complimentarily configured to the threaded members and one of washers 124 (e.g., a lock washer) are disposed between securing member 122 and central wall 116. In one specific example, the support member, the securing members, and the washers are 3⁄8′′ stainless steel. In alternate examples, one or more of the support members and the adjustable height securing members can have a different configuration. In one specific alternate example, the support members can be non-threaded members and the adjustable height securing members can be releasable clamping members.
Looking now at FIG. 6, a second example orientation 136 for the “C” channel elongate frame members will now be described. Second example orientation 136 includes many similar or identical features to configuration 134. Thus, for the sake of brevity, each feature of orientation 136 will not be redundantly explained. Rather, key distinctions between orientations 136 and 134 will be described in detail and the reader should reference the discussion above for features substantially similar between the two orientations.
As shown in FIG. 6, in second example orientation 136, “C” channel elongate frame members are oriented so that open side 114 is faced to a side (i.e., faced toward perpendicular to an underlying ground surface). Accordingly, in the configuration shown in FIG. 6, each elongate frame member 102 includes a central wall 116 with two horizontal side walls 118 extended to parallel to an underlying ground surface away from opposing ends of central wall 116. In this example, central wall 116 is a vertical central side wall, side wall 118a is a bottom horizontal wall, and side wall 118b is a top horizontal waill.
Central wall 116 includes receiving holes 138a for coupling elongate frame members 102 to support members 104. As shown in FIG. 6, support members 104 are threaded members configured to be inserted through holes 138a. Therefore, the through holes are a support member attachment mechanism configured to couple one of the support members to the elongate body of the elongate frame members. Each of adjustable height securing members 122 are positionally adjustable and coupled to one of support members 104 to releasably fix a position of the support member and the elongate frame member. Further, adjustable height securing member 122 is a bottom side securing member (i.e., securing member 122 is secured on bottom of central wall 116).
In the present example, adjustable height securing members 122 are nuts that are complimentarily configured to the threaded members and one of washers 124 are disposed between securing member 122 and side wall 118a. In one specific example, the support member, the securing members, and the washers are 3⁄8′′ stainless steel. In alternate examples, one or more of the support members and the adjustable height securing members can have a different configuration. In one specific alternate example, the support members can be non-threaded members and the adjustable height securing members can be releasable clamping members.
Differently from first example configuration 134, example configuration 136 includes a second securing member 140, which is a top side securing member (i.e., securing member 140 is secured on a top side of wall 118a). Similar to securing member 122, each of securing members 140 are positionally adjustable and coupled to one of support members 104 to assist in releasably fixing a position of the support member and the elongate frame member.
In the present example, securing members 140 are nuts that are complimentarily configured to the threaded members and one of washers 142 are disposed between securing member 140 and side wall 118a. In alternate examples, one or more of the support members and the securing members can have a different configuration. In one specific example, the support members can be non-threaded members and the securing members can be releasable clamping members. In even other alternate examples, the joist system can exclude the top side securing member. Although not specifically shown, it will be appreciated that fastening members 108 can be inserted through and attached to the elongate frame members via holes 120.
FIGS. 7 and 8 show elongate members 102 in configurations 134 and 136, respectively, supporting overlying surface members 112. As depicted in FIG. 7, in configuration 134, central wall 116 is abutted to and supports overlying surface member 112. Alternatively, as depicted in FIG. 8, in configuration 136, side wall 118b is abutted to and supports overlying surface member 112. It will be appreciated that in the second example configuration (where the central wall is a vertical wall) either of side wall 118a or 118b can be a top wall and be abutted to and support the overlying surface member.
In one example, when joist frames at adjoining horizontal surfaces require substrates less than 11⁄4′′, the first example orientation (i.e., first example orientation 134 shown in FIGS. 1-5, 7, and 10) for the elongate frame members can be advantageous due to the low profile design thereby accommodating surrounding height restrictions. Alternatively, in another example where the joist subframe is applied over a primary substrate (e.g., poured concrete slab on grade) and penetrations to the substrate are possible, the second example orientation (i.e., second example orientation 136 shown in FIGS. 6, 8, 9, 11, and 12) position of the elongate frame members coupled with embedded supports provides an increased rigid platform, reducing flex between the adjustable supports due to its configuration. Accordingly, in this example, the second example orientation 136 may be advantageous.
As shown in FIGS. 5-8, an opposing end of each of support: members (i.e., a bottom end of each of the support members) includes a bolt head 126. Bolt head 126 is abutted to foot member 106. In the present example, foot member 106 is a rectangular sheet comprised of a metallic material, such as steel, aluminum, etc. In other examples, the foot member can be comprised of a non-metallic material, such as rubber, cork, etc. Foot member 106 distributes the pressure and/or weight of the support member and the elongate frame member over a wider surface area than the surface area of the bolt head 126. Accordingly, the foot member can be used to prevent penetration of the support member into one or more of an underlying water proofing layer and an underlying surface. In other words, foot member is configured to cushion the bottom end of the support member against the underlying surface. The foot members are “distribution pads”.
Additionally or alternatively, bolt head 126 can be abutted to or coupled with a leveling mount, such as leveling mount 144 shown in FIG. 9. Leveling mount 144 can be comprised of rubber or a metallic material. A variety of leveling mounts can be used in combination with joist system 100, such as those described in U.S. Pat. No. 6,910,666 and U.S. Pat. No. 6,742,750. Further, suitable leveling mounts can include those from available from McMaster-Carr® (e.g., leveling mounts, ultra-high capacity leveling mounts, swivel leveling mounts, stainless steel swivel leveling mounts, bolt down swivel leveling mounts, low -profile swivel leveling mounts, high-capacity acme threaded swivel leveling mounts, etc.). In alternate examples, the support member can exclude the bolt head and can be used in combination with leveling mounts having threaded holes. For example, suitable leveling mounts having threaded holes can include those from McMaster-Carr® (e.g., swivel leveling mounts with threaded holes, bolt-down swivel leveling mounts with threaded holes, etc.).
Turning now to FIG. 10, joist system 100 is shown in combination with a door threshold 148, deck sheeting 150, a waterproof membrane 152, a perimeter drain 154, and a stem wall 156. In the example of FIG. 10, elongate frame members 102 are in configuration/orientation 134 (shown in FIG. 5 and described above). Accordingly, the central wall of each elongate frame member supports overlying surface members 112. It will be appreciated that in alternate examples the elongate members can instead be in configuration/orientation 136 (shown in FIG. 6 and described above). Further, in this example, overlying surface members 112 comprise a deck surface.
Overlying surface members 112 have a level configuration over an inclined ground surface 110. In order to create the level overlying surface, an elongate frame member 102o is fixed/secured at a shorter height over a higher point in the surface, an elongate frame member 102p is fixed/secured at a median height at a median point in the surface, and an elongate frame member 102q is fixed/secured at a higher height at a lower point in the surface. It will be appreciated that more or fewer elongate members fixed at level heights corresponding to their location on the inclined surface can be used to support the overlying surface members.
As shown in FIG. 10, joist system 100 and overlying surface members 112 (e.g., Resysta®, Trex®, Timber Tech®, Fiberon®, Tile and Stone, etc.), are aligned with the horizontal plane of door threshold 148 (e.g., Fleetwood, Pella®, Andersen®, Milgard®, etc.). Used as primary deck framing, joist system 100 allows for easy and secure adjustments to create a level finished surface over a multiple angle substrate and/or waterproofing membrane (e.g., Desotex®, Semco®, Tremco®, Shluter®, etc.). This configuration allows a level surface by use of the joist framing system adjusted over an uneven and/or unlevel ground surface without penetrating in the waterproofing membrane below. Moisture can pass through gaps in decking surface, collect, and/or drain into one or more drains made of PVC, stainless steal, copper, etc. (e.g., drain 154).
FIGS. 11 and 12 show an alternate association of joist system 100 with underlying surface. In this example, support members 104 are inserted into holes 158 in ground surface 110. In other words, the ground surface includes a plurality of receiving holes that are configured to receive a bottom end of one of the support members. Further, in this example, support member 104 excludes a bolt head. A water proofing layer 160 is disposed over the ground surface. Further, water proofing layer 160 covers an opening 162 of hole 158 and encompasses a lower portion of support member 104 (i.e., a portion of support member 104 that is below securing member 122) via a water proof boot 164. The water proof boot forms a water-tight seal around a circumference of the lower end of the support member.
In the depicted example shown in FIGS. 11 and 12, elongate frame members 102 are in configuration/orientation 136 (shown in FIG. 6 and described above). Accordingly, one of the side walls supports overlying surface members 112. It will be appreciated that in alternate examples the elongate members can instead be in configuration/orientation 136 (shown in FIG. 6 and described above). Further, in this example, overlying surface members 112 comprise a deck surface.
Similarly to the example shown in FIG. 10, the example shown in FIG. 12 shows overlying surface members 112 having a level configuration over an inclined ground surface 110. In order to create the level overtone surface, an elongate frame member 102r is fixed/secured at a shorter height over a higher point in the surface and an elongate frame member 102r is fixed/secured at a higher height at a lower point in the surface. It will be appreciated that more elongate members fixed at level heights corresponding to their location on the inclined surface can be used to support the overlying surface members.
In one specific example for FIG. 12, the joist system is attached to vertical 3⁄8 SS all threads by use of 3⁄8 nuts and lock washers anchored with epoxy/adhesive (e.g., Simpson Strong-Tie®, PL Premium®, etc.) into substrates such as concrete by drilling 2′′ deep holes. Once the joist system is attached and adjusted to a level height, the overlying surface members (e.g., Resysta®, Trex®, Timber Tech®, Fiberon®, Tile and Stone, etc.) can be attached. Concrete slabs with a waterproofing membrane (e.g., Dexotex®, Semco®, Tremco®, Shluter®, etc.) applied on a top of the ground surface can be re-waterproofed using waterproofing boots (e.g., vinyl, other water proofing material, etc.). Alternatively, the waterproofing layer can exclude the use of waterproofing boots left when used over surfaces like slab on grade. In this example, water can pass through the gaps in finish surface and be directed to area drains below.
