Definitions
- the present invention is directed to an apparatus for connecting framing components of a building to a foundation.
- the typical platform framing technique which is also the most common light framing construction technique, requires selecting, measuring, cutting, drilling, and assembling many components. Such components typically include a sill sealer, a sill plate, anchors, a rim board (or joist), joists, subfloor panels, and an optional termite shield.
- the sill plates and rim boards serve as the starting point for the remainder of the construction process, as shown in FIG. 1 .
- the sill plate L is secured to a foundation F and provides a nailing base for the other adjoining members.
- the rim board R is placed on-edge and on top of the sill plate L around the outer perimeter of the floor system and transfers stacking gravity loads, such as aligned bearing walls, into the foundation.
- the rim board R also ties the joists J together, thereby improving lateral load resistance of the structure.
- Subflooring panels P are secured to the joists and J and the rim board R. Once the subflooring panels P are installed, the exterior walls of the building are constructed using a bottom plate B, one or more studs S, and top plates (not shown).
- the material used for the rim board is insufficiently flexible and, thus, requires fine tune adjustment to ensure planarity as it is being fastened to the joists, rim board, and adjacent rim boards. The time it takes to make the adjustments is wasteful. Additionally, the quality of materials for the sill plate supplied to the jobsite is often of questionable performance. Thus, the framers typically need to sort through the supply to locate sufficient quality boards, which takes time and is wasteful both in material and labor costs.
- the present invention relates to apparatuses for connecting framing components of a building structure to a foundation wall.
- the apparatus includes a connector having a generally L-shaped cross-section that is configured to be secured to the foundation wall.
- the connector has a joist shelf configured to support one or more floor joists and a recessed area therein, wherein an insulation panel is adhered to the connector within the recessed area.
- the connector further includes a ledge, configured to support one or more wall sheathing panels, proximate the insulation panel.
- the apparatus in another form, includes a plate, wherein the plate is configured to be attached to the foundation wall, and a joist support member attached to a first end of the plate.
- the joist support member is configured to support one or more joists. When the apparatus is secured to the foundation wall and one or more joists are supported by the joist support member, at least a portion of each joist is located at a lower elevation than the plate.
- the apparatus includes a plate that is configured to be secured to the foundation wall and a board that extends generally perpendicularly to the plate and divides the plate into first and second sections.
- the first section is configured to support one or more wall sheathing panels, and the second section is configured to support one or more joists.
- FIG. 1 depicts a cross-sectional view of a conventional, prior art foundation framing system.
- FIG. 2 depicts a perspective view of a portion of an apparatus for connecting framing components of a building to a foundation according to an example embodiment of the present invention.
- FIG. 3 depicts a perspective view of only the plate and board of the apparatus of FIG. 2 .
- FIG. 4 depicts a side view of the apparatus of FIG. 2 .
- FIG. 5 depicts a top view of the apparatus of FIG. 2 and shown without the framing components.
- FIG. 6 depicts a perspective view of a portion of an apparatus for connecting framing components of a building to a foundation according to another example embodiment of the present invention.
- FIG. 7 depicts a side view of the apparatus of FIG. 6 .
- FIG. 8 depicts a side view of an apparatus for connecting framing components of a building to a foundation according to yet another example embodiment of the present invention.

Abstract
Description
- The present invention is directed to an apparatus for connecting framing components of a building to a foundation.
- The majority of buildings, including most single-family and multi-family residences and a large percentage of commercial, institutional, and public buildings constructed in the United States, are framed with wood. Light wood-frame construction adapts readily to the most intricate spaces and architectural forms. The typical platform framing technique, which is also the most common light framing construction technique, requires selecting, measuring, cutting, drilling, and assembling many components. Such components typically include a sill sealer, a sill plate, anchors, a rim board (or joist), joists, subfloor panels, and an optional termite shield.
- Typically, the sill plates and rim boards serve as the starting point for the remainder of the construction process, as shown in
FIG. 1 . The sill plate L is secured to a foundation F and provides a nailing base for the other adjoining members. The rim board R is placed on-edge and on top of the sill plate L around the outer perimeter of the floor system and transfers stacking gravity loads, such as aligned bearing walls, into the foundation. The rim board R also ties the joists J together, thereby improving lateral load resistance of the structure. Subflooring panels P are secured to the joists and J and the rim board R. Once the subflooring panels P are installed, the exterior walls of the building are constructed using a bottom plate B, one or more studs S, and top plates (not shown). - Generally, the material used for the rim board is insufficiently flexible and, thus, requires fine tune adjustment to ensure planarity as it is being fastened to the joists, rim board, and adjacent rim boards. The time it takes to make the adjustments is wasteful. Additionally, the quality of materials for the sill plate supplied to the jobsite is often of questionable performance. Thus, the framers typically need to sort through the supply to locate sufficient quality boards, which takes time and is wasteful both in material and labor costs.
- Proper installation of the sill plates contributes to the finished product quality. If the sill plates are installed correctly (when the sill plates and rim boards are straight and square), the remainder of the construction process will be faster as fewer adjustments are needed. Many times, however, the foundation is not constructed to the specifications required. A homeowner will see the results of a foundation that is more than ⅜ inch out of level or square since these defects translate into visible quality issues of finished materials. For example, tile grout lines will be noticeably out of square with the top of the wall, or hardwood floor boards will appear wedge shaped where the floor meets the wall. Moreover, minor errors at the foundation framing can be exaggerated at the top plate, and the roof trusses may not fit without manual racking. Thus, correcting out of square or out of level foundations typically must take place when installing the sill plate and rim board assembly.
- In addition to the construction problems caused by out of level and square foundations, variations in the foundation create air-leakage points where the sill plate does not conform to the foundation. Current sill sealing practices are insufficient to provide an air tight seal between the concrete foundation and the lower surface of the sill plate. There are additional leak paths between the sill plate and the rim board and the top of the rim board and the bottom surface of the sub-floor that are unaddressed in most construction practices. These leak paths allow air infiltration into the wall cavity where it greatly reduces the insulation effectiveness. These air-leakage points can lead to significant energy losses. Additional significant energy losses occur through conduction of heat energy through large structural member areas such as the rim board.
- Generally described, the present invention relates to apparatuses for connecting framing components of a building structure to a foundation wall. In one form, the apparatus includes a connector having a generally L-shaped cross-section that is configured to be secured to the foundation wall. The connector has a joist shelf configured to support one or more floor joists and a recessed area therein, wherein an insulation panel is adhered to the connector within the recessed area. The connector further includes a ledge, configured to support one or more wall sheathing panels, proximate the insulation panel.
- In another form, the apparatus includes a plate, wherein the plate is configured to be attached to the foundation wall, and a joist support member attached to a first end of the plate. The joist support member is configured to support one or more joists. When the apparatus is secured to the foundation wall and one or more joists are supported by the joist support member, at least a portion of each joist is located at a lower elevation than the plate.
- In yet another form, the apparatus includes a plate that is configured to be secured to the foundation wall and a board that extends generally perpendicularly to the plate and divides the plate into first and second sections. The first section is configured to support one or more wall sheathing panels, and the second section is configured to support one or more joists.

- Referring now to
FIGS. 2 through 5 , an apparatus orconnector 10 for connecting framing components of a building, such as a residential structure, to a foundation F is shown according to a first example embodiment. Theconnector 10 includes a plate orhorizontal member 12 and a board, panel, orvertical member 14 extending generally perpendicularly therefrom. Together, theplate 12 and theboard 14 form a generally L-shaped structure. Theplate 12 comprises a generally rectangular panel having dimensions in the range of 8 to 24 feet long 3½ to 7½ inches wide and 1½ to 3½ inches thick, although these ranges are exemplary and the plate can be larger or smaller, as desired. In a typical commercial embodiment, theplate 12 has dimensions of approximately 16 feet long by 5½ inches wide by 1½ inches thick. - The
plate 12 further has asill sealer layer 16 attached or adhered to its lower surface. Preferably, thesealer 16 is at least about ⅜ inch thick and has a length and width that are the same or approximately the same as the length and width of theplate 12. In alternative embodiments, thesealer 16 is larger or smaller, as desired. Preferably, the thickness of thesill sealer 16 is at least ⅜ inch to accommodate air sealing gaps found commonly in ⅜ inch out of level foundations. In a typical commercial embodiment, thesill sealer 16 comprises a closed cell polyethylene sill sealer (such as the PACTIV BUILDING GSS5055 Sill Seal Gasket), a polyethylene foam (such as Dow STYROFOAM™ SILL SEAL Foam Gasket), or a polyurethane foam (such as expanding polyurethane foam from a can), although other suitable sill sealers can be employed as well. Preferably, theplate 12 andsill sealer 16 have one or more fastening apertures or holes 18 extending therethrough. Eachfastening hole 18 is configured to receive a suitably sized fastener, such as a bolt or anchor (such as the SIMPSON STRONG TIE® Mudsill Anchor in ZMAX) therethrough. - The
board 14 comprises a generally rectangular board or panel having dimensions in the range of 8 feet to 24 feet long, 9½ to 16 inches wide and 1⅛ to 2 inches thick, although these ranges are exemplary and the plate can be larger or smaller, as desired. In a typical commercial embodiment, theboard 14 has dimensions of approximately 16 feet long by 11⅞ inches high by 1⅛ inches thick. - The
board 14 further includes a cutout portion or recessedprofile 20 for receivinginsulation 22, as shown more clearly inFIG. 3 . A pattern press platen can be utilized to impart the recessedprofile 20. Preferably, the recessedprofile 20 extends from lateral edge to edge and to the lower longitudinal edge. Accordingly, theboard 14 includes anoverhang 24 protruding from the body of board. In a typical commercial embodiment, theinsulation 22 is a panel of rigid or semi-rigid foam insulation glued to theboard 14 with a suitable glue or bonding agent, although in alternative embodiments, the insulation can comprise any suitable insulation. Preferably, theinsulation 22 fills the entire void created by the recessed profile, although in alternative embodiments, the insulation fills only a portion of the void. Theinsulation 22 functions as a thermal-break to reduce heat transfer through the large band areas of the house. Theinsulation 22 can include, but is not limited to, Dow STYROFOAM™ extruded polystyrene, a polyisocyanurate, or a polyurethane foam that is glued or otherwise permanently or semi-permanently affixed to theboard 14 within the recessedprofile 20. When theinsulation 22, which is typically in the form of a panel or board stock, is installed within the recessedprofile 20, the combination of theboard 14 andinsulation 22 form a generally rectangular panel having a substantially contiguous surface. In other words, the outer-facing surfaces of theinsulation panel 22 and the outer surface of theoverhang 24 of theboard 24 are generally flush with one another. Advantageously, thethermal insulation 22 laminated to the exterior surface of theboard 14 minimizes conduction losses through this large area of the board. - Along an upper longitudinal or
free edge surface 30 of theboard 14 is a groove orchannel 32 therein for receiving asubfloor gasket 34. In a typical commercial embodiment, thechannel 32 extends the entire length of the upperlongitudinal edge surface 30, although in alternative embodiments, thechannel 32 can extend along a portion or portions thereof. As depicted, thechannel 32 can be a generally square-shaped channel. Thechannel 32 is preferably filled with thesubfloor gasket 34, such as a closed cell polyethylene gasket, a polyethylene foam, or a polyurethane foam, although any other suitable gasket can be employed as well. Thegasket 34 reduces air infiltration between the interface between theboard 14 and the subflooring panels P. - Preferably, the
board 14 is permanently affixed or secured to the plate 12 a distance X from a longitudinal edge thereof. For example, theboard 14 can be secured to theplate 14 with conventional fasteners or fastening techniques, such as gluing and bonding. Also preferably, to provide a secure connection between the plate and board, a tenon and groove joint 40 can be used, although in an alternative embodiment, another suitable joint can be employed. Preferably, the lowerlongitudinal edge surface 42 of theboard 14 has atenon 44 cut therein that mates with a suitably sized andshape groove 46 in an upper surface of theplate 12. Preferably, thegroove 46 is a continuous groove extending along the length of theplate 12. In such an embodiment, theboard 14 can pass through a double end tenoner. On the first or upperlongitudinal edge surface 30, thegroove 32 is cut to house thesubfloor gasket seal 34. On the opposite edge surface (i.e., the lower longitudinal edge surface 42), thetenon 44 is cut to an appropriate size and shape to mate with thegroove 46 of theplate 12. Alternatively, although less preferably, the plate can include the tenon and the board can include the groove. Preferably, a suitable glue or adhesive can be applied along the lowerlongitudinal edge surface 42 and the surfaces of thetenon 44 and/or to thegroove 46 to further bond theboard 14 to theplate 12. For example, a suitable wood adhesive can be machine applied to one or both of theplate 12 andboard 14 at the joint 40 prior to joining the two members together and cured using a high frequency electric gluing machine. - The
groove 46 is cut into the upper surface of the panel a distance X from the firstlongitudinal edge 52 of theplate 12. As depicted, thegroove 46 can be a generally square-shaped groove extending the entire length of theplate 12. Typically, such a square-shapedgroove 46 can be cut with a groove saw or moulder. In alternative embodiments, thegroove 46 can be any suitable size and shape and can extend along only a portion or portions of the length of the plate. Preferably, the distance X is between 1 to 2 inches. In a typical commercial embodiment, the distance X is approximately 1.25 inches. Accordingly, aledge 50 of approximately 7/16 inch is defined between the firstlongitudinal edge 52 of theplate 12 and the edge of theinsulation 22 of theboard 12. Theledge 50 is configured to support a wall sheathing panel W, such as a ZIP SYSTEM® brand wall sheathing panel. A commercially available ZIP SYSTEM® brand wall sheathing panel has a thickness of about 7/16 inches. Thus, when a wall sheathing panel W is installed, the outer-facing surface of the wall sheathing panel is preferably flush with thelongitudinal face 54 of theplate 12. Advantageously, theledge 50 facilitates the installation of the wall sheathing panel W by freeing one hand of the framer/builder that would normally be used to hold the sheathing while concurrently fastening the sheathing to the wall studs. - In an alternative embodiment, the
groove 46 is cut closer to the firstlongitudinal edge 52 of theplate 12 such that the outer surface of theboard 14 or itsinsulation panel 22 is flush with thelongitudinal face 54 of theplate 12. In such an embodiment, there is no ledge for a wall sheathing panel. - A
shelf 60 or generally flat load bearing surface is defined between theboard 14 and the secondlongitudinal edge 62 of theplate 12. Theshelf 60 is configured to receive and support one or more joists J (such as I-joists). Optionally, one or more layout lines, markings, or other suitable indicia, as shown inFIG. 5 , can be marked on theshelf 60 at appropriately spaced repeating intervals to facilitate a perpendicular installation (by aligning the joists thereon). For example, a first set oflayout lines 64 can be spaced 3 ft apart and/or a second set oflayout lines 65 can be spaced 4 ft apart. Optionally, the distance between the lines can be marked on theshelf 60. These lines can be used in conjunction with the concept of the Pythagorean Theorem to speed installation and ensure a square foundation. - Preferably, the
plate 12 and theboard 14 are constructed of a wood composite material, such as, but not limited to, oriented strand board (OSB), particle board, plywood, waferboard, chipboard, medium-density fiberboard, parallel strand lumber, oriented strand lumber (OSL), and laminated strand lumber. In a typical commercial embodiment, theplate 12 comprises OSL and theboard 14 comprises OSB. Preferably, both the OSB and OSL are pressure treated. Also preferably, theplate 12 andboard 14 are treated to be both decay and insect resistant. Optionally, the outer surfaces of theplate 12 andboard 14 can be smoothed with a single or double planar. - In still other alternative embodiments, the
plate 12 andboard 14 can be manufactured by encapsulating an inner structural member with a polymeric material such as in a manner that described in U.S. Patent Application Publication No. 2008/0179418, which is incorporated by reference in its entirety for all purposes. Still alternatively, theplate 12 andboard 14 can comprise a wood thermoplastic composite lumber (WTCL), such as that described in U.S. Patent Application Publication No. 2008/0060295, which is incorporated by reference in its entirety for all purposes and which uses wood flour, high density polyethylene, and other processing additives. In such an embodiment, theplate 12 andboard 14 can be extruded to produce the desired finished shape and dimensions. - Preferably, the
connector 10 is preassembled prior to installation on the building site. In other words, the components of theconnector 10 are preassembled and attached together to provide a “one-piece unit” that can be installed on a foundation. Preferably, there is no assembly of the components on the construction site. Typically, theplate 12 is cut to the appropriate size and has a groove cut along the length of the board at a distance X, which is about 1.25 inches in a typical commercial embodiment, from the longitudinal edge. Theboard 14 is cut to the appropriate size and shape and is passed through a double end tenoner, which cuts thetenon 44 along the lowerlongitudinal edge surface 42 and a channel along the upperlongitudinal edge surface 30. A suitable wood adhesive can be machine applied to one or both of theplate 12 along the lowerlongitudinal edge surface 42 andboard 14 along the upperlongitudinal edge surface 30. Thetenon 44 of theboard 14 can then mated with thegroove 46 of theplate 12 and cured using a high frequency electric gluing machine. Theinsulation panel 22,subfloor gasket 34, andsill sealer 16 can be manually applied using a glue line and/or self-adhesives following the assembly of the two structural members (i.e., the plate and board members). - To install the
connector 10 on the foundation wall F of a building, a builder places theplate 12 of afirst connector 10 on the foundation wall and inserts abolt 66 or other suitable fastener into each of the fastening holes 18 through theplate 12 and tightens the bolts, although other suitable fasteners or fastening techniques can be employed. Asecond connector 10 is similarly connected to the opposing foundation wall. One or more I-joists J are installed and rest on theshelves 60 of the opposingconnectors 10. The joists are nailed to or otherwise secured to the shelves of theboards 14. Following the installation of the I-joists J, one or more subflooring panels P are installed and sealed against air infiltration by thesubfloor gasket 34. Once the subflooring panels P are installed, the exterior walls of the building are constructed using a bottom plate B, one or more studs S, and top plates (on top of the studs, and not shown). Once the walls are plumb and straight, one or more wall sheathing panels W are installed and rest on theledge 50. The wall sheathing panels W improve the racking resistance of the wall. Preferably, a sealing tape such as the ZIP SYSTEM® Tape is applied to seal the seams between adjacent wall sheathing panels W and between the wall sheathing panels W and theplate 12 of theconnector 10 to provide a barrier against air infiltration and to meet current International Code Council (ICC) code requirements. - Preferably, the connectors are installed on all foundation walls, although in other embodiments, the connectors are installed on only two opposing walls. In order to join adjacent connectors in a butt joint configuration, an expansion joint gasket can be used. The expansion joint gasket can comprise a closed cell polyethylene gasket, a polyethylene foam, or a polyurethane foam, although other suitable gaskets can be employed. The expansion joint gasket can be attached to the connector during the assembly of the connector, or the expansion joint gasket can be attached on site. For angled configurations, such as 90 and 135 degree angles, suitably configured corner pieces can be employed. As an alternative to corner pieces, the connectors can be mitre cut or notched and sealed with an expanding foam.
- Advantageously, the
connector 10 is structurally superior to resist bending loads in comparison to the currently constructed sill and rim combination. During the construction process, the added resistance to bending would facilitate a straight and level start when preparing the foundation for the joists. In addition, by combining the components into a single preassembled and generally L-shaped-connector, the potential leak paths created in the traditional framing methods are significantly reduced, if not completely eliminated. Moreover, theconnector 10 automatically creates a barrier to air infiltration that meets currently proposed code requirements. -
FIGS. 6 and 7 depict an apparatus orconnector 110 for connecting framing components to a foundation F according to a second example embodiment. Theconnector 110 includes a plate orhorizontal member 112 and a board, panel, orvertical member 114 extending generally perpendicularly therefrom. Together, theplate 112 and theboard 114 form a generally L-shaped structure. Theplate 112 comprises a generally rectangular panel having dimensions in the range of 8 feet to 24 feet long, 8 to 16 inches wide, and 1 to 3 inches thick, although these ranges are exemplary and the plate can be larger or smaller, as desired to accommodate various foundation nominal dimensions. In a typical commercial embodiment, theplate 112 has dimensions of approximately 16 feet long by 9 9/16 inches wide by 1½ inches thick. - The
plate 112 includes a recessedprofile 120 cut into a first major surface (i.e., the lower surface that engages the foundation wall) that extends between its lateral edges for fitting over the foundation wall F. Accordingly, the recessedprofile 120 is suitably sized and shaped such that the foundation wall F fits snugly within the recessed profile and abutslongitudinal end portions plate 112. Within the recessedprofile 120 is acutout area 126 for housing asill sealer 128. Preferably, the recessed cutout area is approximately 5½ inches wide by ¼ inch high and runs the entire length of theplate 112, although the dimensions can vary. Preferably, thesealer 128 is at least about ⅜ inch thick and has a length and width that are the same or approximately the same as the length and width of thecutout area 126 of theplate 112. In alternative embodiments, thesealer 128 is larger or smaller, as desired. Preferably, the thickness of thesill sealer 128 is at least ⅜ inch to accommodate common ⅜ inch out of level foundations. In a typical commercial embodiment, thesill sealer 128 comprises a closed cell polyethylene sill sealer, although other suitable sill sealers can be employed as well. - The
plate 112 also includes aplate shelf 130 or stepped area cut in an upper surface thereof. Theplate shelf 130 is suitably sized and shaped to receive and hold a conventional base plate B and is at a lower elevation than the secondlongitudinal end portion 124. Preferably, theshelf 130 is approximately ¼ inch lower than the secondlongitudinal end portion 124. The purpose of thisshelf 130 is to align the vertical wall created by the base plate B, the stud S, and the top plate with theconnector 110. Proximate theplate shelf 130 is aledge 140 extending near the edge of the firstlongitudinal end 122. Theledge 140 is at a lower elevation than theplate shelf 130. Preferably, theledge 140 is approximately ¼ inch lower than theshelf 130. Also preferably, theledge 140 is configured to support a wall sheathing panel W, such as a ZIP SYSTEM® brand wall sheathing panel. When the sheathing panel W is installed, it abuts the base plate B and stud S, and is generally flush with theouter surface 142 of firstlongitudinal edge portion 122 of theplate 112. - The
plate shelf 130 has acutout portion 144 therein for receiving asubfloor gasket 146. Preferably, thecutout portion 144 is approximately 5½ inches wide by ¼ inch high and runs the entire length of theplate 112, although the dimensions can vary. A plurality of fastening holes orapertures 148 extend through thesubfloor gasket 146 andsill sealer 128 and are configured to receive one or more fasteners (e.g., bolts 66) therethrough for securing theconnector 110 to the foundation wall F. - The
board 114 extends from the lower surface of the secondlongitudinal edge portion 124 of theplate 112, thereby creating the general L-shape. Preferably, theboard 114 andplate 112 can be separate members that are glued, bonded, or otherwise affixed together. In such an embodiment, optionally, a tenon and groove joint glued together or other suitable joint (such as discussed above with reference to the connector 10) can be used to provide a more secure connection between theplate 112 and theboard 114. In an alternative embodiment, theboard 114 is extruded and formed integral with theplate 112. At the opposite ordistal end 150 of theboard 114 is ajoist shelf 152 or horizontal member projecting therefrom for supporting one or more joists J. As depicted, thejoist shelf 152 is glued, bonded, or otherwise affixed to theboard 114 and can include a tenon and groove joint or other suitable joint. In an alternative embodiment, thejoist shelf 152 can be integral with theboard 114. Thejoist shelf 152 can comprise a generally rectangular board having a load bearing surface with dimensions in the range of 1½ inches to 3 inches long, 8 to 24 feet wide, and 1 to 4 inches thick, although these ranges are exemplary and thejoist shelf 152 can be larger or smaller as desired. In a typical commercial embodiment, thejoist shelf 152 has dimensions of approximately 2 inches long, 16 feet wide, and 3½ inches thick. Optionally, one or more layout lines or other suitable indicia, similar to those of theconnector 10, can be marked on the joist shelf at appropriately spaced intervals to facilitate a perpendicular installation. - Preferably, the
plate 112 and theboard 114 are constructed of a wood composite material or other material that is the same as or similar to the material used to construct theplate 12 andboard 14 of thefirst connector 10. Similar to thefirst connector 10, preferably theplate 112 andboard 114 are treated to be both decay and insect resistant. - Preferably, the
connector 110 is preassembled prior to installation on the building site. In other words, the components of theconnector 110 are preassembled and attached together to provide a “one-piece unit” that can be installed on a foundation wall F. Preferably, there is no assembly of the components on the construction site. Typically, theplate 112 is cut to the appropriate size and has the various cutout and recessed portions cut therein. Theboard 114 is cut to the appropriate size and shape and its proximal longitudinal surface is glued to the lower surface of the secondlongitudinal portion 124 of theplate 112. Thejoist shelf 152 is secured to thedistal end 150 of the board with a suitable glue, bonding agent, or other fastener. Thesubfloor gasket 146 andsill sealer 128 can be manually applied using a glue line and/or self-adhesives following the assembly of the two structural members (i.e., the plate and board members). - To install the
connector 110 on the foundation wall F of a building, a builder places the recessedprofile 120 of afirst connector 110 over the foundation wall and secures it thereto by inserting abolt 66 or other suitable fastener into each of the fastening holes 148 through theplate 112 and tightening the bolts, although other suitable fasteners or fastening techniques can be employed. Asecond connector 110 is similarly connected to the opposing foundation wall. One or more I-joists J are installed and rest on thejoist shelves 152 of the opposingconnectors 110. The joists are nailed to or otherwise secured to theshelves 152 and the longitudinal surfaces of theboard 114 andend portion 124 of theplate 112. Following the installation of the I-joists J, one or more subflooring panels P are installed on the secondlongitudinal end portion 124 of theplate 112. Once the subflooring panels P are installed, the exterior walls of the building are constructed using a bottom or base plate B that is installed on theplate shelf 130 and sealed against air infiltration by thesubfloor gasket 146. One or more studs S and top plates (on top of the studs and not shown) are installed. Once the walls are plumb and straight, one or more wall sheathing panels W are installed and rest on theledge 140. The wall sheathing panels W improve the racking resistance of the wall. Preferably, a sealing tape such as the ZIP SYSTEM® Tape is applied to seal the seams between adjacent wall sheathing panels W and between the wall sheathing panels W and theplate 112 of theconnector 110 to provide an air barrier and to the current approved code amendments. -
FIG. 8 depicts an apparatus orconnector 210 for connecting framing components to a foundation F according to a third example embodiment. Theconnector 210 is substantially similar to theconnector 110 but with the exceptions noted herein. - The
connector 210 has a generally T-shaped plate orhorizontal member 212. The plate has abody member 214 withcutout portions sill sealer 220 andsubfloor gasket 222, respectively. Thecutout portions sill sealer 220, and thesubfloor gasket 222 are substantially similar to those ofconnector 110. A plurality of fastener holes 224, similar to the fastener holes 148 of theconnector 110, extends through the subfloor gasket and sill sealer, and each hole is configured to receive one or more fasteners (e.g., bolts 66) therethrough for securing theconnector 210 to the foundation wall F. - The
plate 212 includes afirst flange 230 that engages the foundation wall F when installed thereto. Theplate 212 also includes asecond flange 232 extending oppositely from thefirst flange 230 to engage at least a portion of the base plate B. A wall sheathing panel W can rest on a top surface orledge 234 of thesecond flange 232. Preferably, the width of theledge 234 corresponds to the thickness of the wall sheathing panel W such that the outer-facing surface of the wall sheathing panel is flush with the outer longitudinal surface of the plate. - A plurality of conventional
metal joist hangers 240 are connected to the secondlongitudinal edge surface 242 of theplate 212. Eachjoist hanger 240 wraps around the lower flange of the joist, securely holds the joist, and couples it directly to the foundation. One or more conventional fasteners can secure thejoist hangers 240 to the joists J. Preferably, thejoist hangers 240 are secured to theplate 212 at appropriately spaced intervals. For example, a joist hanger can be secured at every 12, 16, or 24 inches on center. - Preferably, the
connector 210 is preassembled prior to installation on the building site. In other words, the components of theconnector 210 are preassembled and attached together to provide a “one-piece unit” that can be installed on a foundation. Preferably, there is no assembly of the components on the construction site. Typically, theplate 212 is cut to the appropriate size having the twoflanges metal joist hangers 240 are secured to the secondlongitudinal edge surface 242 with suitable fasteners (e.g., bolts) or fastening techniques. Thesubfloor gasket 220 andsill sealer 222 can be manually applied using a glue line and/or self-adhesives. - To install the
connector 210 on the foundation wall F of a building, a builder places theplate 212 of afirst connector 110 over the foundation wall such that thefirst flange 230 engages the foundation wall. The builder secures theplate 212 thereto by inserting abolt 66 into each of the fastening holes 148 and tightening the bolts, although other suitable fasteners or fastening techniques can be employed. Asecond connector 210 is similarly connected to the opposing foundation wall. A single I-joist J is installed in each of the joist hangers 40 (and opposing hangers 40) such that each hanger wraps around the lower flange portion of the joist. One or more fasteners can be inserted through the hangers to further secure the joists to the hangers. Following the installation of the I-joists J, one or more subflooring panels P are installed and sealed against air infiltration by thesubfloor gasket 220. Once the subflooring panels P are installed, the exterior walls of the building are constructed using a bottom plate B, one or more studs S, and top plates (on top of the studs, and not shown). Once the walls are plumb and straight, one or more wall sheathing panels W are installed and rest on theledge 234 of thesecond flange 232 to improve the racking resistance of the wall. Preferably, a sealing tape such as the ZIP SYSTEM® Tape is applied to seal the seams between adjacent wall sheathing panels W and between the wall sheathing panels W and the plate of theconnector 210 to provide an air barrier and to meet the currently approved code amendments. - Advantageously, the
connectors connectors - Advantageously, the
connectors connectors connectors - While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
