Disclosed herein, in various aspects and with reference to
The following illustrated cross sections are not drawn to scale and are provided to generally describe cross sectional shapes. The cross sections can be described with reference to a first transverse dimension 144 and a second transverse dimension 145 that is perpendicular to the first transverse dimension.
Referring to
The first and second channels 102A, 102B can be disposed so that the inner surfaces of their respective base walls 106A, 106B oppose each other. The first channel 102A and the second channel 102B can be positioned so that their respective channels 120A, 120B cooperate to define an interior passage 142. According to at least one embodiment, as shown in
Referring to
The first and second outer channel members 202A, 202B can be disposed so that the respective inner surfaces of the base walls and side walls can cooperate to define the respective channels 220A, 220B. The first side walls 208A, 208B can have ends 231A, 231B opposite the respective base wall 206A, 206B, and the second side walls 210A, 210B can have ends 233A, 233B opposite the respective base wall 206A, 206B. As shown in
Referring to
Although the inner member is shown as a channel having a C-shaped profile or a U-shaped profile in the Figures, it should be understood that the inner member can have various other profiles, such as, for example, that of an I-beam, Z-channel, track, threaded rod with mounting plates, cold formed tube steel, or hollow structural tube. Accordingly, although references herein are made specifically to the inner member 104, it should be understood that a U-shaped inner channel member 204, as shown in
Referring to
Offsetting the end(s) can be accomplished, in some embodiments, by providing an inner member having a length that is greater than or less than the lengths of the first and second outer channel members 102A, 102B. In some embodiments, the inner member 104 can have a length 105 that is greater than half of the length 103A of the first outer channel member 102A and the length 103B of the second outer channel member 102B. The length 103A of the first outer channel member 102A can preferably be equal to the length 103B of the second outer channel member 102B, and respective longitudinal ends of the first and second outer channel members 102A, 102B can preferably be aligned. (It should be understood that respective ends of a member in relation to another member of the same structural member assembly can refer to ends on the same longitudinal end of each channel member. For example, the first end 160A of the first outer channel member 102A and the first end 160B of the second outer channel member 102B can be the “respective” ends with respect to the first end 164 of the inner member 104.) However, in optional embodiments, the length 103A of the first outer channel member 102A can be greater than or less than the length 103B of the second outer channel member 102B.
In providing at least one offset between at least one longitudinal end of the inner member and the respective longitudinal ends of the outer channel members, portions of adjacent structural member assemblies 100 can be nested, as disclosed herein. In this way, the plurality of structural member assemblies 100 can easily and efficiently be stacked end-to-end. For example, referring to
Although the steps disclosed herein refer to empty portions of interior passages receiving inner members, it should be understood that, in embodiments consistent with this disclosure, adjacent pairs of inner members can be positioned end-to-end, and the outer channel members can then be positioned around the adjacent pair of inner members and coupled via fasteners to the pair of inner members. Accordingly, stacking of structural member assemblies 100, as disclosed herein, should be understood to describe the arrangement of the coupled structure, rather than the order in which the components are coupled. As disclosed herein, “respective longitudinal ends” of adjacent structures/members should be understood to include opposing ends of adjacent structures/members. For example, referring to
The method of alternatingly attaching outer channel members of one structural member assembly to inner channel members of adjacent structural member assemblies can be repeated to create support columns of various lengths. In some embodiments, support columns 300 may comprise, two, three, four, five, or more structural member assemblies 100. Because the inner members are shorter than the outer channel members, an additional inner member 310 can extend through an empty portion 322″ of an interior passage 142″ of the structural member assembly 100″ so that the collective length 312 of the inner members 104, 104″, 104′″ and the additional inner member 310 is substantially equal to the collective length 316 of the stacked outer channel members. According to some aspects, the ends of structural member assemblies 100 can directly abut respective adjacent structural member assemblies. However, it should be understood that this disclosure include support columns having some longitudinal spacing (e.g., less than one inch, less than two inches, or less than four inches) between adjacent structural member assemblies, or between components of adjacent structural member assemblies. Moreover, it should be understood that structural member assembly components that are separated by spacing components (e.g., spaced by the thickness of the coupling plates 650 or the thickness of the alignment plate 600) should fall within aspects of this disclosure. For example, it should be understood that adjacent ends of adjacent center members 140 that “extend to” each other can include ends of adjacent center members that engage the same alignment plate 600. Moreover, it is contemplated that center members that are spaced from adjacent center members can optionally “extend to” each other if they are longitudinally spaced by no more than one inch, by no more than two inches, or by no more than four inches. Similarly, members that are aligned “end-to-end” should be understood to include members that are abutting each other, spaced by a spacing component such as a coupling plate 650 or an alignment plate 600, or longitudinally spaced by no more than one inch, by no more than two inches, or by no more than four inches.
It should be understood that each inner member need not have the same length as the other inner members in a support column. For example, referring to
In further embodiments, at least one inner member can be longer than its respective first and second outer channel members. For example, referring to
Optionally, with reference to
Referring to
The alignment bracket 600 can have a depending flange 610 that extends downward and generally perpendicularly to the rectangular profile of the alignment bracket. The depending flange 610 can be disposed adjacent a base wall 170 of the inner member 104, and the pair can be coupled with fasteners 150. In this way, the top end of the inner member 104 can be positioned within the interior passage 142.
The alignment bracket 600 can have a circumferential upwardly extending projection 620 that defines a gap 622 on each side for receiving the inner member 104′ therein. For example, the circumferential upwardly extending projection 620 can comprise first edges 624 and second edges 226 that extend in the longitudinal dimension 101 and are spaced from each other in the second transverse dimension 145. The first edge 624 can define a first stop to constrain a back surface (e.g., an outer surface of the base wall 170 (
Although the disclosure refers to the inner member 104 as a unitary body, it should be understood that, in some embodiments, the inner member 104 can comprise a plurality of coupled components. For example, referring to
Structural member assemblies 100 and support columns 300, as discussed herein, can provide various improvements over known structural members. According to one aspect, the structural member assemblies 100 can be made partially or entirely of light gauge steel, thereby providing structural support at a low weight and cost. Moreover, the ends of the inner members that are offset from the ends of the outer channel members enable the structural member assemblies 100 to be nested so that adjacent structural member assemblies can easily be stacked to create support columns 300. Additionally, the inner members 104 of the support columns 300 not only provide surface for coupling adjacent structural member assemblies 100; the inner members 104 can provide structural support to the support columns 300. According to some aspects, a plurality of inner members 104 can cooperate to define an inner support that extends along an entire length, or substantially an entire length, of the support column 300. That is, the center supports 104 can provide both surfaces for easy attachment of adjacent structural member assemblies and structural support along the entire length of the support column. Because the structural member assemblies 100 can be stacked as disclosed, the cross sectional profiles of respective structural assemblies, in planes perpendicular to the longitudinal dimension, can be the same. Accordingly, disclosed embodiments can be distinguished from conventional assemblies that employ nested members having sequentially smaller cross sections. Optionally, the columns 300 can be used in multi-level construction, such as for multi-level storage structure buildings. The disclosed structural members can have improved load carrying capacity and strength over conventional structural members. Further, the disclosed columns having structural members with offset ends can have greater shear strength than conventional systems. For example, in conventional multi-level storage structure buildings, structural columns have longitudinal ends that terminate at each floor, wherein adjacent columns are coupled at adjoining ends to create unions having weak shear strength. In contrast, the disclosed embodiments can create a single continuous structural column that does not have unions with weak shear strength. Improved shear strength can be particularly critical for providing stability in seismic or earthquake zones.

In providing the bridge channel member 806 with a C-shaped profile, the bridge channel member 806 can define flanges 812 that extend inwardly into the beam's interior volume 808 and engage the concrete to increase the composite beam's overall strength. Prior to hardening/curing of the concrete, it is contemplated that the concrete can be positioned both above and below each flange 812 such that the flange is surrounded by or embedded within the concrete. After hardening/curing of the concrete, it is contemplated that the flange can provide support to the concrete during flexing or other movement of the beam and distribute forces between the concrete and the steel channel members. In some embodiments, the flanges can extend into the interior volume 808 at about one third of the height of the beam. That is, the length of the first and second legs of the bridge channel member 806 can be about one third of the height of the beam. Accordingly, for a six inch tall beam, the flanges can extend inwardly at about two inches from the bottom of the beam.
Additionally, or alternatively, the beam 800 can comprise a plurality of internally projecting members 820 that are spaced along the beam's longitudinal axis 810. The internally projecting members 820 can be configured to engage the concrete to distribute forces between the concrete and the steel channel members. Prior to hardening/curing of the concrete, it is contemplated that the concrete can be positioned to surround or embed the internally projecting members 820 within the concrete. After hardening/curing of the concrete, it is contemplated that the projecting members 820 can provide support to the concrete during flexing or other movement of the beam and distribute forces between the concrete and the steel channel members.

Each of the internally projecting members 820, return flanges 838, straps 860, and depending internally projecting components 862 can enhance the engagement between the steel members and the concrete to provide a composite beam having improved strength over conventional beams. Because the transition height, as disclosed above, can vary, based on parameters of the beam, the combination of the internally projecting members 820, return flanges 838, straps 860, and depending internally projecting components 862 provides for composite action along the height of the beam, enabling composite action closest to the transition height, regardless of the position of said transition height along the height of the beam. The disclosed configuration can further be cheaper to manufacture and more simple to assemble, thereby reducing assembly time over conventional framing methods. Many or all of the components of the beam 800 can be off-the-shelf items, thereby providing for low cost and easy procurement. As the beams 800 can be attached to columns in a compound span configuration, the beams can be attached more easily and in a configuration having greater overall strength than conventional simple span beams. Additionally, the disclosed embodiments enable easier field modification than conventional trough designs; because the beam spans across columns rather than fitting between the columns, the beam's steel channel members can be cut in situ. Moreover, conventional beams comprise heavy gauge steel, which can increase cost and weight without substantially enhancing the strength of the beam. Accordingly, the light gauge steel can decrease the cost and the weight of the beam.
Although disclosed as separate and independent components, it is contemplated that any of the beam structures disclosed herein can be used in combination with any of the structural member assemblies disclosed herein to form a support structure for a building or other construction.
