System and method having an improved beam and beam coupling system

[0001] This invention relates to a building system, and more particularly, to a system that utilizes an improved beam and coupling system for building a frame or structure.

[0002] The aluminum enclosure industry and patio screen enclosure roof systems typically utilized beams comprising two identical halves. The halves simply overlap and were stitched or screwed together with a plurality of screws to make one complete self-mating beam. In some applications, an entire extruded one-piece beam was used.

[0003] One problem with the prior art beam structures is a high failure rate during strong winds, especially hurricane-force winds. The box beam failed for many reasons including the fact that the beam web was simply overlapped and laid on top of each other. An improved beam system that overcame some problems of the prior art is shown in U.S. Pat. No. 7,877,962; U.S. Design Pat. Nos. D620,618; D620,619; D636,095; D666,743; D713,054 and D791,342, all of which are incorporated herein by reference and made a part hereof.

[0004] The beam structures of the prior art had to use a plurality of horizontal and vertical beams to create a frame onto which a mesh screen was mounted. Typically, a top spanning horizontal beam could only span approximately six to ten feet before a vertical column support or column beam had to be used to support the weight of the top beam. One problem with the designs and structures of the prior art is that the number of vertical and horizontal beams obstructed the view of persons inside the structure who were looking out. For example, if the structure was a lanai structure, it is not uncommon that people in the lanai like to view the scenery outside of the lanai, whether it be a scenic water view, a golf course view or a wooded area view, but the vertical and horizontal columns were aesthetically unpleasing and at least partially obstructed that view.

[0005] Another problem is that oftentimes main spanning beams typically did not have spline grooves and a separate beam having the spline grooves had to be secured thereto and used, adding parts and manufacturing costs to the structure. For example, it was not uncommon that a 1″×2″ beam having at least one or a plurality of spline grooves for receiving and securing the screen to the beams had to be mounted on top of a primary support beam that would be used for building the structure frame. The additional lanai screen beam was typically mounted onto the primary support beam and provided the spline groove or channel that was necessary to mount the mesh screen onto the frame. Of course, the additional 1″×2″ beam having the spline groove also added additional material and installation cost to the framing structure.

[0006] To overcome some of these problems, some attempts have been made to make the beams more robust by, for example, making the beam walls much thicker, so that they withstand longer span lengths. Several problems arise with increasing the size of the beams, including increased weight and cost to name a few. As the length of the beams increased along with the need to carry heavier loads, bigger and heavier beams had to be created. As enclosure sizes and span lengths increase, the box and hollow beams that were used to make the enclosures in the past had to be made with much thicker and heavier extrusions in order to achieve the span lengths desired. Unfortunately, these extrusions were typically more expensive and resulted in increased costs.

[0007] Some homeowners or builders are building larger and more dynamic structures, such as pool enclosures and lanais, with the same historical products, resulting in structures that have undesirable viewing obstructions, failure rates and/or costs.

[0008] Another problem with the typical beams of the past is that they had to utilize through-bolts and fascia fasteners to secure the beams together or to another structure. The through-bolts and fascia fasteners are aesthetically unpleasing.

[0009] Still another problem is that a typical building structure that was framed using a prior art beam system had to utilize steel cables or tie-downs for lateral structural support. The lateral tie-downs added material and installation costs to the overall structure.

[0010] Still another problem with the prior art framing structures is that the beams typically had to be mounted to other structures, such as a patio deck, floor or wall using a plurality of L-shaped brackets situated on opposite sides of the beam and fastened thereto and to the other structure. These brackets and fastenings all added additional installation time and cost. Some people found the mounting brackets to be aesthetically unpleasing as well.

[0011] There is, therefore, a need to provide an improved building structure having an improved beam and coupling system that overcomes one or more of the problems of the prior art.

[0012] One object of the invention is to provide an improved beam and coupling system for building a structure.

[0013] Another object of the invention is to provide a beam and coupling system that can span greater lengths.

[0014] Still another object of the invention is to provide a stronger beam and coupling system that has a large viewing area that is uninterrupted by horizontal or vertical support beams of the type used in the prior art.

[0015] Still another object of the invention is to provide a beam and coupling system that eliminates the need for fasteners on the fascia sides of the beam.

[0016] Still another object of the invention is to provide a beam and coupling system for making a frame that reduces or eliminates the need for through-fasteners or fasteners that are screwed into the fascia sides of the beam.

[0017] Still another object of the invention is to provide an improved beam and coupler system for creating a frame that reduces or eliminates the need for tie-down cables.

[0018] Another object of the invention is to provide a corner coupler for securing a plurality of beams together to form a corner of the framing structure.

[0019] Another object of the invention is to provide an elongated coupler for coupling or splicing two beams together.

[0020] Yet another object of the invention is to provide a coupler having at least a portion that can be mounted to a support structure, such as a patio deck, concrete slab, building wall, structure or the like.

[0115] These and other objects and advantages of the invention will be apparent from the following description, the accompanying drawings and the appended claims.

[0131] Referring now to FIGS. 1A-12I, a system and method for constructing a structure 10 is shown. In the illustration being described, the structure 10 defines at least one of a lanai, screen enclosure, carport, walkway cover or other outdoor or indoor framed structure. In the illustration being described, the structure 10 is a lanai frame 12 that supports a mesh screen 14 of the type conventionally known. The structure 10 is a lanai that is attached to a building 16, such as a house, office or other structure, as illustrated in FIGS. 1A-1C. One significant advantage of the structure 10 is that it reduces or eliminates a number of vertical and horizontal beams that were traditionally required in the past so that it provides relatively large viewing areas VA that are unobstructed by beam structure. Of course, the structure 10 also requires fewer beams. Consequently, the structure 10 is less expensive than comparable wide view systems of the past. This is advantageous, for example, when people are located inside the lanai and viewing the environment outside of the lanai. For ease of illustration, the viewing area is labeled VA in FIGS. 1A and 1B.

[0132] The embodiments illustrated in FIGS. 1A and 1B illustrate the contrast between a screen wall that defines a large viewing area VA and one that does not. For example, FIG. 1A illustrates a screen wall 14a that defines a side of the lanai structure 10. Note that other than the primary horizontal support beam 11 and lateral support beam 22, there are no horizontal or vertical support beams or columns that are necessary to support the screen wall 14a in FIG. 1A. In contrast, note in FIG. 1B that a side wall 18 is defined by a plurality of screens 14b that are supported by a plurality of vertical and horizontal beams 20 and 21, respectively. Note the difference in FIGS. 1A and 1B, with the wall 18 in FIG. 1B being typical of the prior art. The embodiments described and claimed herein advantageously permit an entire wall to be formed and defined by the screen 14 while reducing or eliminating vertical or horizontal support beams of the past, thereby providing the large viewing area VA.

[0133] The structure 10 is typically mounted to a support structure, such as a concrete or cement slab and/or the building 16 to which it is attached. Details of the structure 10 and its various components will now be described.

[0134] For ease of illustration, FIG. 1C is a view taken in the direction of arrow A in FIG. 1A showing a plurality of vertical beams 22 and 24 that extend from a surface or support structure 26, such as a concrete slab, and that are coupled to at least one or a plurality of horizontal beams 28 and 30 as shown. In the illustration being described, the structure 10 comprises at least one or a plurality of beams, such as beams 11, 20, 21, 22, 24, 28 and 30. The structure 10 further comprises at least one or a plurality of internal couplers 32, 34 and 36 as shown in FIG. 1C. In the illustration being described, note that the at least one or a plurality of internal couplers 32, 34 and 36 are received inside the beam structures 22, 24, 28 and 30 as shown. For ease of illustration, the beams 22, 24, 28 and 30 shown in FIG. 1C are partially fragmented to show the at least one or a plurality of internal couplers 32, 34 and 36. It should be understood that the beams 11, 20, 21, 22, 24, 28 and 30 receive the at least one or a plurality of internal couplers 32, 34 and 36 and are fastened thereto. The at least one or a plurality of internal couplers 32, 34 and 36 are positioned inside the beams and not visible to the naked eye. In the illustration being described, the at least one coupler 32 is a corner coupler and couples two beams, such as beams 22 and 30, together such that they are oriented relative to each other at an angle B of approximately 90 degrees as illustrated in FIG. 1C. Details of the corner key or corner coupler 32 are illustrated in FIGS. 2A-2E, which will now be described. FIG. 2E is an enlarged view after the corner coupling 32 is mounted in the beams 24 and 28.

[0135] The at least one splicing coupler 34 is generally elongated and linear and couples two beams, such as beams 28 and 30, together as illustrated in FIG. 1C. Note, for example, the beams 28 and 30 are coupled together using a splice coupler 34 in accordance with one embodiment of the invention. Details of the at least one coupler 34 are illustrated in FIGS. 5A-5E. Finally, the at least one support coupler 36 supports or secures at least one beam to a support structure, such as the building 16 of the surface or support structure 26. FIG. 1C illustrates the at least one or a plurality of internal couplers 36 mounted to the surface or support structure 26 and the beams 22 and 24 mounted thereon. The details of the at least one coupler 36 are shown in FIGS. 6A-7E.

[0136] Referring now to FIG. 2A, details of the at least one coupler 32 will now be described. In the illustration being described, the at least one coupler 32 comprises a body having a first portion 32a and a generally orthogonal second portion 32b, each of which generally comprises an I-beam or H-beam shape in cross-section (depending on viewing orientation) as illustrated in FIG. 3. Note that each of the embodiments of the at least one or a plurality of internal couplers 32, 34 and 36 comprises a similar cross-sectional configuration.

[0137] For ease of description, the shape, configuration and operation of the first portion 32a and second portion 32b will be described, with it being understood that the couplers 34 and 36 of the other embodiments described herein have the same or generally similar cross-sectional shape and operate and function in the same or generally similar manner as that which is now being described in FIGS. 2A-2E.

[0138] For ease of illustration, the at least one coupler 32 is shown in FIG. 2A, with it being understood that the at least one coupler 32 is a corner key or corner coupler that couples beams 24 and 28 together to form an elbow or corner. The at least one coupler 32 has the first portion 32a that is received in a beam end 24a of the vertical beam 24. Likewise, the at least one coupler 32 comprises the second portion 32b that is received in a beam end 28a of the horizontal beam 28. In the illustration being described, the coupler portions 32a and 32b are each generally in the shape of an I in cross-section and are received inside the beams 24 and 28. For ease of manufacturing, the at least one coupler 32 is comprised of the first portion 32a and the second portion 32b as illustrated in FIG. 2A. The portions 32a and 32b comprise ends 32a1 and 32b1 (FIG. 2A) that are miter cut at approximately 45 degrees and then brought together in a fixture (not shown) and fastened together, such as by at least one weld 40 (FIG. 2A), adhesive, screw, glue or other type of bond or fastener.

[0139] Referring back to FIGS. 2A-2E, it should be understood that the portions 32a and 32b are sized and adapted to be press-fit or fit snugly into the ends 24a and 28a, respectively. Notice in the sectional view in FIG. 3 that the coupler portion, such as coupler portion 32b, is adapted and sized to be inserted into a beam (beam 28 in the illustration). Preferably, the at least one coupler 32 is sized, shaped and adapted to be press-fit into the beams 24 and 28 or otherwise fit snugly therein. It has been found that the at least one or a plurality of internal couplers 32, 34 and 36 increase an overall strength of the spanning beam. The inventor has found that increasing the internal enforcement/reinforcement length allows for a greater transfer of load to the substrate or beam.

[0140] In the illustration being described, each of the beams 24 and 28 (FIG. 3) comprises a plurality of internal wall surfaces, some of which either contact or become juxtaposed next to at least a portion of the at least one coupler 32. For example, the beam 28 comprises a plurality of beam walls 28a, 28b, 28c and 28d (FIG. 3) having internal beam wall surfaces 28a1, 28b1, 28c1 and 28d1, respectively. These walls 28a-28d cooperate to define an aperture 42 into which the portion 32b may be situated. As mentioned earlier herein, the at least one coupler 32 is adapted and dimensioned to be received in the aperture 42 and comprises a plurality of coupling surfaces described herein that become positioned or juxtaposed in operative relationship with the plurality of internal wall surfaces 28a1-28d1 of the at least one support beam 28.

[0141] As best illustrated in FIGS. 2A and 3 and as mentioned earlier herein, note that each of the at least one or plurality of couplers 32, 34 and 36 have a cross-sectional shape that is generally in the form of an I or an H depending on one's viewing angle. The first and second portions 32a and 32b of the at least one coupler 32 cooperate to generally define an L-shape as shown in FIGS. 2A-2E and 9A-9H, and this predetermined configuration will now be described relative to FIG. 3.

[0142] As previously mentioned, each of the at least one or plurality of couplers 32, 34 and 36 have a generally common cross-sectional configuration, although they could be slightly different in size, dimension or shape depending on the beam into which they are received. For ease of description, the configuration, mounting, shape and operation of the at least one coupler 32 and beam 28 will be described. The second portion 32b comprises a first flange 44, a second flange 46 and a rib or web 48 that is monolithically formed with the first and second flanges 44 and 46 as shown in FIG. 3. Note that the flanges 44 and 46 are generally U-shaped (as viewed in FIG. 3) in cross-section, with their openings facing each other. In this regard, note that the first flange 44 is integral or monolithically formed in a first end 48a of the rib 48 and the second flange 46 is integral and monolithically formed with a second end 48b of the rib 48.

[0143] The flanges 44 and 46 have a first elongated portion 44a and 46a, respectively, which are generally parallel to each other and generally perpendicular to the rib 48. The flange 44 comprises a monolithic or integral first flange wall 44b and a second flange wall 44c, both of which are generally parallel to the rib 48 as shown. The flange walls 44b and 44c are integrally or monolithically formed and coupled to the flange elongated portion 44a by beveled or truncated wall portions 44d and 44e, respectively, as shown. The second flange 46 also comprises a third flange wall 46b and a fourth flange wall 46c, both of which are generally parallel to the rib 48. Note that the third and fourth flange walls 46b and 46c are also integrally or monolithically formed with the first elongated portion 46a by a truncated or beveled portion 46d and 46e as shown.

[0144] It is important to note that the beveled portion 44d comprises a surface 44d1 that cooperates with the interior surfaces 28d1 and 28a1 of the beam 28 to define an interior internal triangularly shaped aperture or channel 50. Likewise, the beveled portion 44e comprises a surface 44e1 that cooperates with the interior surfaces 28d1 and 28b1 to define an interior aperture or channel 52. The beveled portion 46d comprises a corner or surface 46d1 that cooperates with the interior surfaces 28c1 and 28a1 to define an interior aperture or channel 54. Finally, the beveled portion 46e comprises a surface 46e1 that cooperates with the interior surfaces 28c1 and 28b1 to define the interior generally rectangular shaped and elongated aperture or channel 56.

[0145] In the illustration being described, the channels 50-56 generally extend in the beam 28 the lengths L1 and L2 (FIG. 2B) of the portions 32a and 32b. Thus, the channels 50-56 for the corner coupler 32 extend a length L3 and L4 (FIG. 2A).

[0146] It is important to note that the truncated portions 44d, 44e, 46d and 46e all facilitate defining the interior channels 50-56, respectively, that have or define a predetermined shape. The channels 50-56 are adapted to accommodate an internal beam structure, such as an internal beam structure 60 (shown in the enlarged view in FIG. 3) of the at least one or plurality of support beams 22, 24, 28 and 30. In the illustration being described, the internal beam structure 60 (FIG. 3) may comprise a spline groove channel wall or projection 62 that cooperates with a flange 64 to define a first spline groove or channel 66 for receiving the screen 14 and a conventional spline (not shown) for retaining this screen 14 in the spline groove or channel 66. The spline groove or channel 66 opens in a direction of arrow C in FIG. 3. Note that the spline groove channel wall or projection 62 extends into and is accommodated by the interior aperture or channel 52 of the beam 28 as illustrated. The beam 28 has a second projecting portion 70 that cooperates with a flange 72 to define a second spline groove or channel 74. The portion 70 also extends into the area 68 as shown in FIG. 3 and into the aperture or channel 54 as illustrated in FIG. 3. It should be appreciated that the beam 28 in this example has only two spline grooves or channels 66 and 74 (FIGS. 3 and 4), but more or fewer spline grooves or channels could be provided. It should be understood that in the prior art, the beams typically had a spline groove used for either a roof screen or wall screen, but not both. In fact, it was not uncommon that a second beam structure, such as a 1″×2″ beam having a spline groove had to be mounted to a primary beam to provide a spline groove for the wall screen.

[0147] Advantageously, the at least one corner coupler 32 is adapted, shaped and sized to accommodate the internal beam structure 60 and it has been found that the beveled corners facilitate inserting the at least one corner coupler 32 into the beams 24 and 28. It is significant to note that the spline groove or channel 66, for example, is located on the wall 28b and faces outward from the fascia wall surface 28b2 in the direction of arrow C as illustrated in FIG. 3. In contrast, the spline groove or channel 74 is located catty-corner or generally diagonally to the spline groove or channel 66 and opens in a direction facing arrow D (FIG. 3), which is generally orthogonal to the direction C of channel 66. This different orientation of spline grooves or channels 66 and 74 enables the beam 28 to accommodate the vertical wall screens 14b (FIG. 1A) and the angled or horizontal ceiling screen 14c. The embodiments shown and described herein provide the beam 28 that has spline grooves 66 and 74 for the wall and roof screen, without the need of additional beam or extrusion structures

[0148] FIG. 4 shows a typical beam 28 in the illustration being described. In the illustration, the beam 28 is 4″×8″ and of varying lengths. The plurality of internal couplers 32, 34 and 36 and the beam 28, as well as the other beams shown and described herein, are made of aluminum. Likewise, the at least one or a plurality of internal couplers 32, 34 and 36 are generally integral or monolithically formed or manufactured and are made of aluminum, but could be made of other material, such as steel, metal alloys or any other suitable metal.

[0149] Advantageously, the at least one or a plurality of internal couplers 32, 34 and 36 are adapted, sized and shaped to accommodate the internal beam structure 60 of the beam being used. While the embodiment being shown shows that each of the flanges 44 and 46 have multiple truncated corners, it should be appreciated that each flange 44 and 46 may be provided with only one truncated corner, depending on the beam 28 being used. If the beam 28 has other internal beam structures that need to be accommodated, then the corners of the flanges 44 and 46 or other portions of the coupler 32 may be truncated, recessed or indented so that accommodating apertures or channels can be provided.

[0150] FIGS. 2B-2E illustrate the assembly of the structure using the corner key coupler 32. In the illustration being described, note that the beams 24 and 28 have the mitered or angled ends 24a and 28a that receive the first portion 32a and the second portion 32b, respectively. The second portion 32b of the coupler 32 is guided into and received in the end 28a of the beam 28 and the first portion 32a of the coupler 32 is guided into and received in the end 24a of the beam 24, as illustrated in FIGS. 2C and 2D, respectively. As illustrated in FIG. 2C, after the second portion 32b is received in the beam 28, the screws or fasteners 80 are used to fasten the beam 28 to the coupler 32 as shown. Likewise, after the first portion 32a is received in the beam 24, the screws or fasteners 80 are used to secure the beam 24 to the first portion 32a as illustrated in FIG. 2D. Once these parts are assembled, the vertical beam 24 is coupled to the beam 28, and they form generally a ninety degree (90°) angle to define a corner of the structure 10.

[0151] It is important to note the positioning of the screws or fasteners 80, which is a unique feature of the embodiments. In this regard, note that beam 28 has the generally opposing end walls 28c and 28d (FIG. 3) that are typically oriented as illustrated in FIG. 3 and fascia walls 28a and 28b that are relatively longer and define side walls or fascia of the beam 28. Note that none of the screws or fasteners 80 are screwed into the fascia walls 28a and 28b when coupling the corner coupler 32 to the beam 28. As best illustrated in FIGS. 2A-2E, after the corner coupler 32 is received in the ends 24a and 28a of the beams 24 and 28, respectively, the screws or fasteners 80 are used to secure the beams 24 and 28 to the corner coupler 32. Note also that the screws or fasteners 80 extend through one of the beam walls 28c and 28d. In this regard, note that the screws or fasteners 80 only extend through one of the end walls, such as wall 28c or wall 28d of beam 28, and into the flanges 44 and 46 (FIG. 3) as shown. Likewise, beam 24 is similarly secured with the screws or fasteners 80 to the first portion 32a of the coupler 32.

[0152] In contrast, it was not uncommon in the prior art that through-bolts were mounted completely through the fascia or side faces, such as ends or fascia walls 28a and 28b of beam 28, which is aesthetically unpleasing.

[0153] Advantageously, the embodiment being described eliminates or reduces the need for such through-bolts and fascia fasteners.

[0154] After the screws or fasteners 80 have secured the beams 24 and 28 to the corner key or corner coupler 32, as illustrated in FIGS. 2D and 2E, note that the joint between the beams 24 and 28 increases the overall strength and support of the structure 10 and increases the lateral support. Advantageously, the embodiment being described may reduce or eliminate the need for traditional tie-down cables in view of the increased strength and resilience of the improved coupling between the beams 24 and 28.

[0155] It is important to note that the couplers 32, 34 and 36 and, for example, the first and second portions 32a and 32b, are sized and adapted depending upon a plurality of factors, including the desired overall span length, such as an overall desired length of beams 28 and 30. In this regard, note that the first portion 32a and second portion 32b of the corner coupler 32 have the lengths L1 and L2, respectively, that are generally the same in the illustration being described. It should be understood, however, that these lengths L1 and L2 could be different. In general, the couplers 32, 34 and 36 are dimensioned and sized based upon engineering requirements for the building or structure 16. The coupler 34 has a length L5 (FIG. 5A) and the coupler 36 has a length L6 (FIG. 6A). These lengths are selected depending upon several factors, such as an overall span length, such as beams 28 and 30, beam dimensions, and, for example, distance from the building 16. One predominate factor is the overall span length of the beams 28 and 30. In general, the portions 32a and 32b may be increased or decreased in response to a longer or shorter, respectively, span length. Again, various factors influence the size, length and/or shape of the couplers 32, 34 and 36 based on design load, distance from the building 16, height and length of the structure 10 walls.

[0156] After the beams 28 and 30 are coupled together, the coupler 32 is not visible to the naked eye as illustrated in FIG. 2E. Note also that the fascia or sides, such as side wall or fascia wall 28a and side wall or fascia wall 28b (FIG. 3), do not have any visible screws or fasteners 80, which is more aesthetically pleasing compared to prior art assemblies.

[0157] Referring now to FIG. 5A, the elongated splicing coupler 34′ is shown. Like parts for this embodiment and for the embodiment showing the coupler 36′ are identified with the same part numbers, except a prime mark (“′”) for the splicing coupler 34′ embodiment and 36′ for the coupler 36′ embodiment have been added. As illustrated in FIGS. 5A-5E, note that generally equal portions 34a′ and 34b′ of the elongated coupler 34′ are received in the beams 28′ and 30′, respectively, and the screws or fasteners 80′ (FIGS. 5B-5E) are used to secure them together as illustrated. The coupler 34′ in the illustration being described has the same or substantially similar generally I or H shape and cross-sectional configuration as the cross-sectional first and second portions 32a and 32b of the coupler 32.

[0158] The coupler 34′ is adapted and sized to be received in the beams 28′ and 30′ and splice them as illustrated in FIGS. 2C and 5A-5E. Once generally equal parts of the coupler 34′ are received in the beams 28′ and 30′, the screws or fasteners 80′ secure the beams 28′ and 30′ to the coupler 34′ in a manner similar to the corner key coupler 32 described earlier herein. As mentioned, the coupler 34′ has a general I or H shape depending on orientation as with the prior embodiments and has generally U-shaped flanges 44′ and 46′, with beveled corners or surfaces 44d1′, 44e1′, 46d1′ and 46e1′, as with the embodiment described relative to the corner key coupler 32′. Again, a length L5 (FIG. 5A) of the coupler 34′ is directly related to a desired overall span length of the beams 28′ and 30′ when they are coupled together. In other words, the length L5 is increased for greater desired span lengths and decreased for lesser span lengths, depending on the building structure 10′ or the overall desired span length of the joined beams 28′ and 30′.

[0159] It should be understood that while the embodiment illustrated shows only one coupler 34′ coupling the beams 28′ and 30′, multiple couplers 34′ could be used in an overall span. Shorter couplers 34′ are required for shorter lengths, whereas longer couplers 34′ or multiple couplers 34′ may be required for longer lengths. Again, the overall length and size of the coupler 34′ is selected depending upon the size and dimensions of the beams 28′ and 30′ and overall span length desired and the size of the structure 10′ being built.

[0160] The coupler 34′ comprises the first portion 34a′ (FIGS. 5B-5E) and the second portion 34b mentioned earlier that are received in the ends 28b′ and 30a′ of the beams 28′ and 30′, respectively. The components and parts 28′, 30′ and 34′ are moved relative to each other such that the portion 34b′ is received in the end 30a′ of the beam 30′ and the portion 34a′ is received in the end 28b′ of the beam 28′ as illustrated in FIGS. 5C and 5D. Once an end, such as end 28b′ or end 30a′, has been received on the first and second portions 34a and 34b, respectively, the screws or fasteners 80′ are used to secure the beams 28′ and 30′ to the coupler 34′ as shown. As with the previous embodiment being described relative to the corner key coupler 32, note in FIG. 5E that the coupler 34′ is not visible to the naked eye once the beams 28′ and 30′ are received on the coupler 34′ and the screws or fasteners 80′ secured thereto.

[0161] The intermediate or splicing coupler 34′ enables the coupling of beams 28′ and 30′ to provide an overall elongated beam which is beneficial for providing longer spans and increased large viewing aspect. In the illustration being described, the beams 28′ and 30′, once spliced together, can span a predetermined length selected by the user. In the illustration, the length is typically less than 50 feet. Note that in the prior art, beams of this length could only be achieved by increasing an overall size or dimension of the beam. For example, the wall thickness of the prior art beams was increased, which also typically increased the overall cost of the beam and structure.

[0162] Advantageously, the embodiments described herein can be used with beams, such as beams 28 and 30, that have reduced wall thicknesses compared to that of the prior art. It should be understood that the couplers 32, 34 and 36 could also be used with a split beam, such as the split beam shown or having the features of the beams shown in U.S. Pat. No. 7,877,962; U.S. Design Pat. Nos. D620,618; D620,619; D636,095; D666,743; D713,054 and D791,342, all of which are incorporated herein by reference and made a part hereof.

[0163] Another embodiment illustrates a support coupler 36″ (FIGS. 6A-6E) that has a cross-sectional shape that is similar to the shape of the cross-sectional shape of the couplers 32 and 34. In this embodiment, like parts are identified with the same part numbers as in prior embodiments and operate in substantially the same manner except that a double prime mark (“″”) has been added to the like part numbers for this embodiment. The coupler 36″ has a similar I-beam or H-beam shape in cross-section as in prior embodiments and further comprises an end plate or wall 90 that is situated on and fastened to a support, such as the surface or support structure 26″ of a concrete slab, patio deck, beam, building wall or other support surface onto which the coupler 36″ may be mounted using screws or fasteners 82, as illustrated in FIGS. 6B-6D. Note that a vertical or horizontal beam, such as beam 22, is received and mounted on the coupler 36″ in a manner similar to the prior embodiments using the screws or fasteners 80″ as shown. In this illustration, the coupler 36″ has a length L6 (FIG. 6A) that is substantially shorter than the lengths L1-L5 of the prior embodiments. It should be understood, however, that each of the lengths L1-L6 could be longer or shorter and are selected in response to the beam size and dimension and the overall structural support needed.

[0164] As with the prior embodiments, once the beam, such as beam 22″, is mounted to the surface or support structure 26″ with fasteners 82 (FIGS. 6A-6D). The fasteners 80″ are used to secure the beam 22″ to the coupler 36″ as illustrated in FIGS. 6A-6E. As shown in FIG. 6E, the coupler 36″ itself is not visible to the naked eye.

[0165] As mentioned earlier, the coupler 36″ has a cross-sectional shape that is generally the same or similar to the cross-sectional shapes of the couplers 32 and 34 and functions and operates similarly as described earlier herein relative to FIGS. 1-5E. One advantageous feature of the coupler 36″ is that it is adapted to be secured to any suitable support surface. In the illustrations being described in FIGS. 6A-6E, the surface or support structure 26″ could be a patio deck, cement slab, building wall or other structure associated with building 16. In the example in FIGS. 6A-6E, the beam 22″ is mounted on the coupler 36″ and is generally vertical.

[0166] FIG. 6F is an enlarged view of the coupler 36″ that shows the plate or wall 90 that has a plurality of internal aperture walls 92a-92d that define a plurality of apertures 94a-94d, respectively, for receiving the fasteners 82. The coupler 36″ (FIG. 6F) comprises the flanges 44a″ and 46a″ and the rib 48″. The flanges 44a″ and 46a″ and rib 48″ operate and have generally the same shape, configuration and structure as the flanges 44a and 46a and rib 48 in the embodiment shown in FIG. 3 relative to the coupler 32. What is unique about the coupler 36″ is that it has the plate or wall 90 integrally or monolithically formed or fastened to an end 36a by, for example, a weld or adhesive. The plurality of internal aperture walls 92a-92d that define a plurality of apertures 94a-94d, respectively, for receiving the fasteners 82 for securing or mounting the coupler 36″ to the support surface or structure.

[0167] FIGS. 7A-7E show another embodiment wherein the coupler 36″ is mounted directly to another beam, such as one of the joined beams 24″ and 11″ as illustrated in FIG. 7A. Again, like parts are identified with the same part numbers as in prior art embodiments and operate in substantially the same manner except that a triple prime mark (“′″”) has been added to the part numbers of the like parts in this embodiment. Another beam, such as beam 92 (FIG. 7A), may then be mounted on the coupler 36′″ using the fasteners 80′, thereby securing the beams 24′″, 11′″ and 92 together as illustrated in FIGS. 7A-7E. In the example, the beams 28′″ and 92 are generally horizontal. FIGS. 7B-7E show views taken in the direction of arrow D in FIG. 7A illustrating the corner key coupler 32′″ and the coupler 36′″ joining beams 24′″ and 11″′ as shown. Once the coupler 36′″ is mounted on the beams 24′″ and 11′″ using fasteners 80, the beam 92 may be mounted on the coupler 36′″ as illustrated in FIGS. 7B-7E and the screws or fasteners 80′″ are used to secure the beam 92 to the beams 24′″ and 11′″ as shown.

[0168] FIG. 8 illustrates another application of the coupler 36′″. In this embodiment, the coupler 36′″ is mounted directly to a gutter 16a′″ or surface of the building structure 16′″ as shown. In this embodiment, the beam 11′″ is mounted to the coupler 36′″ which in turn is mounted to the gutter 16a′″ or other structure of the building 16′″ and supports the beam 11′″ in a generally horizontal plane. In the embodiment illustrated in FIGS. 7A-7E, the beam 92 is generally horizontal and generally orthogonal to the beam 11′″ to which it is attached. In contrast, the embodiment illustrated in FIGS. 6A-6E, the beam 92 lies in a generally vertical plane and provides a generally vertical support beam or column.

[0169] It should be understood that during construction of the structure 10 in one embodiment, the vertical beams 22 and 24 (FIG. 1C) are mounted to the structure or building 16 using the coupler 36. These vertical beams 22 and 24 are attached or secured to the horizontal beams 28 and 30 using the corner key couplers 32. The beams 28 and 30 are attached to each other using the splice coupler 34. Once the beams and couplers 22-36 are coupled together, they define the structure 10.

[0175] Some additional advantages and considerations of the embodiments are listed below:

[0176] Eliminates need for through-bolts and fascial fasteners.

[0177] A length of the couplers 34 and 36 and corner coupler key 32 increases an overall span of beam.

[0178] The corner coupler 32 increases lateral support and may reduce or eliminate cable tie downs.

[0179] A position of spline groove eliminates need for separate and additional spline beams, such as the prior art 1″×2″ beam that was typically mounted on the horizontal support beams.

[0180] The coupler 36 can be mounted to any internal coupler including a substrate.

[0181] The embodiments can be used with split beams and beams of U.S. Pat. No. 7,877,962; U.S. Design Pat. Nos. D620,618; D620,619; D636,095; D666,743; D713,054 and D791,342.

[0182] Design eliminates face screws and also bolts.

[0183] The hollow one piece beam having built in spline grooves like those shown in FIG. 3 eliminates the need for additional 1″×2″.

[0184] The couplers 32, 34 and 36 are not visible once installed in the beams.

[0185] An increase in overall strength, spanning length, and robustness is improved by the embodiments being described herein as well as the size, length and other dimensions of the couplers 32, 34 and 36.

[0186] The corner coupler 32 bonds and couples beams together to form a corner having plane and unobstructed fascia surfaces, which is aesthetically pleasing.

[0187] Advantageously, the embodiments shown and described herein could be used alone or together and/or in combination with one or more of the features covered by one or more of the claims set forth herein, including but not limited to one or more of the features or steps mentioned in the Summary of the Invention and the claims.

[0188] While the system, apparatus and method herein described constitute preferred embodiments of this invention, it is to be understood that the invention is not limited to this precise system, apparatus and method, and that changes may be made therein without departing from the scope of the invention which is defined in the appended claims.
