[0025] Throughout the accompanying drawings, corresponding reference numerals indicate the corresponding parts. Detailed Implementation

[0026] In general, the attachment devices described herein are used for attachment to structural members. The attachment devices can be fixed to any structural element of a building, such as beams, floors, or ceilings. In the illustrated embodiments, the attachment device is fixed to an I-beam. Any suitable restraints or anti-sway supports (such as longitudinal or transverse anti-sway supports / restraints) can be attached to the attachment device to secure non-structural members to structural members. Each attachment device is configured to securely attach to the structural member (i.e., the I-beam / log lumber) and provides a raised attachment position for mounting fittings to the attachment device. Thus, the attachment device is configured to mount fittings in a location that does not obstruct surrounding members of the structural member. Additionally, one or more attachment devices provide attachment to the structural member without forming pre-drilled holes through it. Therefore, the attachment device is configured to maintain the strength and integrity of the structural member after attachment.

[0027] See Figure 1 An example of a suitable anti-sway support or restraint that can be used with the various attachments described below is generally indicated by reference numeral 10. As is commonly known in the art, the anti-sway support / restraint 10 includes a strut 12 (e.g., a pipe, strip, rod, etc.) and opposing connecting fittings 14 at each end of the strut. One connecting fitting 14 can be used to attach the anti-sway support / restraint 10 to a structural component (e.g., an I-beam of a building), and the opposing connecting fittings 14 can be used to attach the anti-sway support / restraint to a non-structural component (e.g., a pipe, conduit, tube, fitting, etc.). When the attachment is coupled to a non-structural component, the anti-sway support / restraint spans between the structural and non-structural components, thereby supporting the non-structural component in the building. In the illustrated embodiment, each connecting fitting 14 is identical and defines a fastener opening 16 for attaching the connecting fitting to any of the various attachments, as described in more detail below. It should be understood that... Figure 1The anti-sway support / restraint 10 described herein is exemplary, and the various attachment devices disclosed herein can be used with any suitable anti-sway support / restraint. For example, the anti-sway support / restraint may be an earthquake anti-sway support / restraint. Furthermore, it is contemplated that any of the various attachment devices described below may be directly connected to the strut 12 of the anti-sway support / restraint 10 (e.g., replacing one of the connecting fittings 14 at one end of the strut 12), as is generally known in the art.

[0028] See Figures 2 to 4 A first embodiment of the attachment device for connecting to a structural component is generally indicated by reference numeral 20 in the attached drawing. For example... Figure 2 As shown, the attachment device 20 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting 14 for attachment to suitable anti-sway support restraints, etc. The attachment device 20 includes a body or plate member 22 configured to attach to the web W of the I-beam J. The plate member 22 has a planar portion 24 and a raised portion 26. The planar portion 24 provides a contact surface for engaging the web W of the I-beam J. In the illustrated embodiment, the attachment device 20, particularly the plate member 22, has a rectangular shape. However, without departing from the scope of this disclosure, the attachment device 20 may be formed in any suitable shape, such as circular or elliptical. A pair of slots in the plate member 22 extend along the height of the attachment device 20 between the top and bottom of the attachment device. A first slot 28 is disposed adjacent to a first longitudinal end of the attachment device 20, and a second slot 29 is disposed adjacent to a second longitudinal end of the attachment device. In the illustrated embodiment, each slot 28, 29 comprises a continuous slot. However, each of the slots 28, 29 may include a plurality of discrete slots spaced apart along the height and / or length of the plate member 22. One or more fasteners 30 are received in the slots 28, 29 for securing the attachment device 20 to the web W of the joist J. In one embodiment, the fastener 30 is a self-tapping wood screw configured to drill into the wooden joist J. Therefore, no pre-drilled holes for receiving standard bolts are formed in the joist J.

[0029] The protrusion 26 is disposed within the planar portion 24 such that the protrusion is surrounded by the planar portion on all sides. In the illustrated embodiment, the protrusion 26 includes a circular projection including a curved peripheral edge 32 projecting away from the planar portion 24 and an engagement surface 34 of the plane defined by the peripheral edge. Thus, the engagement surface 34 of the plane lies in a plane spaced apart from the plane of the planar portion 24 in a direction extending orthogonally to both planes. A hole (not shown) is configured to receive a fastener (not shown) for attaching the fitting 14 to the attachment device 20. Thus, the fitting 14 is spaced sufficiently from the web W of the joist J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 20 in any desired angular orientation. The fitting 14 can also be attached to the attachment device 20 without creating a through hole in the web W of the joist J. Although the protrusion 26 is shown as a circular projection, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0030] The attachment device 20 can be considered as the first attachment device and is configured for attachment to the first surface of the web W of the joist J. See also Figure 3 and Figure 4 The second attachment device 20A is configured to attach to the opposite face of the web W of the support beam J. The second attachment device 20A is substantially similar to the first attachment device 20. However, in addition to the slots 28A and 29A, the second attachment device 20A also includes hook members 36A disposed at each end of the slot. Each hook member 36A includes a first arm extending orthogonally from the planar portion 24A and a second arm extending substantially parallel to the planar portion. The block member 38A is held to the second attachment device 20A by the hook members 36A. Specifically, the block member 38A has a height extending parallel to the planar portion 24A and a thickness extending perpendicular to the planar portion 24A, such that the size and shape of the block member are set to be received within the space formed by the hook members 36A and the planar portion 24A. Thus, the first arm of the hook member 36A engages the top and bottom sides of the block member 38A respectively, and the second arm of the hook member engages the outward surface of the block member to support and hold the block member to the second attachment device 20A. In one embodiment, block component 38A comprises wood, plastic, or composite material. Other materials for block components are also conceivable.

[0031] When the fastener 30 is inserted through the slots 28 and 29 in the first attachment device 20, the fastener passes through the web W of the joist J, through the slots 28A and 29A in the second attachment device 20A, and into the block member 38A. Thus, the self-tapping wood screw 30 is anchored in the block member 38A. The fastening engagement between the fastener 30 and the block member 38A secures both the first attachment device 20 and the second attachment device 20A to the web W of the joist J. Furthermore, the block member 38A is thicker than the web W of the joist J, and therefore provides a more robust and mechanically reliable structure for receiving the fastener than if only the web W of the joist J were used.

[0032] See Figure 5 A second embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 120. The attachment device 120 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting 14 for attachment to suitable anti-sway support restraints, etc. The attachment device 120 includes a body or plate member 122 configured to attach to the web W of the I-beam J. The plate member 122 has a planar portion 124 and a protruding portion 126. The planar portion 124 provides a contact surface for engaging the web W of the I-beam J. In the illustrated embodiment, the attachment device 120, and in particular the plate member 122, has a rectangular shape. However, without departing from the scope of this disclosure, the attachment device 120 may be formed in any suitable shape, such as circular or elliptical. Fastener holes in the plate member 122 are configured to receive fasteners 130 for securing the attachment device 120 to the web W of the I-beam J. In one embodiment, the fastener 130 is a wood screw configured to drill into the wooden joist J. Therefore, no pre-drilled holes are formed in the joist J to receive standard bolts.

[0033] The protrusion 126 is typically positioned in the middle of the planar portion 124, such that the protrusion is surrounded on both sides by the planar portion. In the illustrated embodiment, the protrusion 126 includes a generally rectangular or trapezoidal projection including a curved longitudinal edge 132 projecting away from the planar portion 124 and a planar engagement surface 134 between the longitudinal edges. Thus, the planar engagement surface 134 lies in a plane spaced apart from the plane of the planar portion 124 in a direction extending orthogonally to both planes. The post 140 extends from the planar engagement surface 134 for attaching the fitting 14 to the attachment device 120. Therefore, the fitting 14 is spaced sufficiently from the web W of the joist J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 120 in any desired angular orientation. The fitting 14 can also be attached to the attachment device 120 without creating a through-hole in the web W of the joist J. Although the protrusion 126 is shown as a rectangular or trapezoidal protrusion, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0034] The attachment device 120 can be considered as the first attachment device and is configured for attachment to the first surface of the web W of the joist J. See also Figure 6 The second attachment 120A is configured to attach to the opposite face of the web W of the joist J. The second attachment 120A includes a block member 138A. In one embodiment, the block member 138A comprises wood, plastic, or a composite material. Other materials for the block member are also contemplated. When a fastener 130 is inserted through a fastener hole in the first attachment 120, the fastener passes through the web W of the joist J and into the block member 138A. Thus, the self-tapping wood screw 130 is anchored in the block member 138A. The fastening engagement between the fastener 130 and the block member 138A secures both the first attachment 120 and the second attachment 120A to the web W of the joist J. Furthermore, the block member 138A is thicker than the web W of the joist J, and therefore provides a more robust and mechanically reliable structure for receiving the fastener than if only the web W of the joist J were used.

[0035] See Figure 7 and Figure 8 A third embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 220. The attachment device 220 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting 14 for attachment to suitable anti-sway support restraints, etc. The attachment device 220 includes a body or plate member 222 configured to attach to the web W of the I-beam J. The plate member 222 has a protrusion 226 and a plurality of planar portions 224. The planar portions 224 provide contact surfaces for engaging the web W of the I-beam J. In the illustrated embodiment, the plate member 222 has a generally T-shaped form. However, without departing from the scope of this disclosure, the plate member 222 may be formed in any suitable shape, such as circular or rectangular. Fastener holes in the plate member 222 are configured to receive fasteners 230 for securing the attachment device 220 to the web W of the I-beam J. In one embodiment, the fasteners 230 are standard bolt fasteners.

[0036] A protrusion 226 is positioned in the middle of the planar portion 224, such that the protrusion is surrounded by the planar portion on its top, bottom, left, and right sides. In the illustrated embodiment, the protrusion 226 includes a rectangular projection comprising a curved side edge 232 projecting away from the planar portion 224 and a planar engagement surface 234 between the side edges. Thus, the planar engagement surface 234 lies in a plane spaced from the plane of the planar portion 224 in a direction extending orthogonally to both planes. A post 240 extends from the planar engagement surface 234 for attaching the fitting 14 to the attachment device 220. Therefore, the fitting 14 is spaced sufficiently from the web W of the joist J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 220 in any desired angular orientation. The fitting 14 can also be attached to the attachment device 220 without creating a through-hole in the web W of the joist J. Although the protrusion 226 is shown as a rectangular protrusion, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0037] See Figure 9 A fourth embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 320. The attachment device 320 is configured to attach to a structural component (such as a wooden I-beam / sawn timber) and to a connecting fitting 14 for attachment to suitable anti-sway support restraints, etc. The attachment device 320 includes a body or plate member 322 configured to attach to the web W of the I-beam. The plate member 322 has a planar portion 324 and a raised portion 326. The planar portion 324 provides a contact surface for engaging the web W of the I-beam. In the illustrated embodiment, the attachment device 320, and in particular the plate member 322, has a rectangular shape. However, without departing from the scope of this disclosure, the attachment device 320 may be formed in any suitable shape, such as circular or elliptical. Fastener holes (not shown) in the plate member 322 are configured to receive fasteners 330 for securing the attachment device 320 to the web W of the I-beam. In one embodiment, the fastener 330 is a standard bolt fastener.

[0038] The protrusion 326 is disposed within the planar portion 324 such that the protrusion is surrounded by the planar portion on all sides. In the illustrated embodiment, the protrusion 326 includes a circular projection comprising a curved peripheral edge 332 projecting away from the planar portion 324 and an engagement surface 334 of the plane defined by the peripheral edge. Thus, the engagement surface 334 of the plane lies in a plane spaced apart from the plane of the planar portion 324 in a direction extending orthogonally to both planes. A hole (not shown) is configured to receive a fastener 340 for attaching the fitting 14 to the attachment device 320. Thus, the fitting 14 is spaced sufficiently from the web W of the joist to prevent engagement of the fitting with the joist flange. This allows the fitting 14 to be attached to the attachment device 320 in any desired angular orientation. Although the protrusion 326 is shown as a circular projection, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0039] See Figure 10 A fifth embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 420. The attachment device 420 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting 14 for attachment to suitable anti-sway support restraints, etc. The attachment device 420 includes a body or plate member 422 configured to attach to the web W of the I-beam J. The plate member 422 has a planar portion 424 and a raised portion 426. The planar portion 424 provides a contact surface for engaging the web W of the I-beam J. In the illustrated embodiment, the attachment device 420, and in particular the plate member 422, has a rectangular shape. However, without departing from the scope of this disclosure, the attachment device 420 may be formed in any suitable shape, such as circular or elliptical. Fastener holes (not shown) in the plate member 422 are configured to receive fasteners 430 for securing the attachment device 420 to the web W of the I-beam. In one embodiment, the fastener 430 is a standard bolt fastener.

[0040] The protrusion 426 is typically positioned in the middle of the planar portion 424, such that the protrusion is surrounded on both sides by the planar portion. In the illustrated embodiment, the protrusion 426 includes a generally rectangular or trapezoidal projection including a curved longitudinal edge 432 projecting away from the planar portion 424 and a planar engagement surface 434 between the longitudinal edges. Thus, the planar engagement surface 434 lies in a plane spaced apart from the plane of the planar portion 424 in a direction extending orthogonally to both planes. A hole (not shown) is configured to receive a fastener 440 for attaching the fitting 14 to the attachment device 420. Therefore, the fitting 14 is spaced sufficiently from the web W of the joist J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 420 in any desired angular orientation. The fitting 14 can also be attached to the attachment device 420 without creating a through-hole in the web W of the joist J. Although the protrusion 426 is shown as a rectangular or trapezoidal protrusion, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0041] Additionally, flange 450 extends laterally from the bottom edge of plate member 422 on the opposite side of protrusion 426. Flange 450 provides a mating surface with the lower flange F of support beam J. For this purpose, flange 450 supports attachment device 420 under vertical load conditions. Therefore, the overall size of attachment device 420 is reduced, while the load-bearing capacity of the attachment device is increased.

[0042] See Figure 11 A sixth embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 520. The attachment device 520 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting for attachment to suitable anti-sway support restraints, etc. The attachment device 520 includes a body or plate member 522 configured to attach to the web W of the I-beam J. The plate member 522 has a planar portion 524 and a protruding portion 526. The planar portion 524 provides a contact surface for engaging the web W of the I-beam J. In the illustrated embodiment, the attachment device 520, especially the plate member 522, has a generally rectangular shape. However, without departing from the scope of this disclosure, the attachment device 520 may be formed in any suitable shape, such as circular or elliptical. Fastener holes (not shown) in the plate member 522 are configured to receive fasteners 530 for securing the attachment device 520 to the web W of the I-beam J. In one embodiment, the fastener 530 is a standard bolt fastener.

[0043] A protrusion 526 is disposed within the planar portion 524 such that the protrusion is surrounded by the planar portion on all sides. In the illustrated embodiment, the protrusion 526 includes a circular projection comprising a curved peripheral edge 532 projecting away from the planar portion 524 and an engagement surface 534 of the plane defined by the peripheral edge. Thus, the engagement surface 534 of the plane lies in a plane spaced apart from the plane of the planar portion 524 in a direction extending orthogonally to both planes. A post 540 extends from the engagement surface 534 of the plane for attaching the fitting 14 to the attachment device 520. Therefore, the fitting 14 is spaced sufficiently from the web W of the joist J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 520 in any desired angular orientation. The fitting 14 can also be attached to the attachment device 520 without creating a through-hole in the web W of the joist J. Although the protrusion 526 is shown as a circular protrusion, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0044] Additionally, flange 550 extends laterally from the bottom edge of the planar portion 524 of plate member 522. Flange 550 provides a mating surface with the lower flange F of support beam J. For this purpose, flange 550 supports attachment device 520 under vertical load conditions. Therefore, the overall size of attachment device 520 is reduced, while the load-bearing capacity of the attachment device is increased.

[0045] See Figure 12 and Figure 13 A seventh embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 620. The attachment device 620 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting 14 for attachment to suitable anti-sway support restraints, etc. The attachment device 620 includes a body or plate member 622 configured to attach to the web W of the I-beam J. The plate member 622 has a planar portion 624 and a raised portion 626. The planar portion 624 provides a contact surface for engaging the web W of the I-beam J. In the illustrated embodiment, the attachment device 620, and in particular the plate member 622, has a rectangular shape. However, without departing from the scope of this disclosure, the attachment device 620 may be formed in any suitable shape, such as circular or elliptical. Fastener holes (not shown) in the plate member 622 are configured to receive fasteners 630 for securing the attachment device 620 to the web W of the I-beam. In one embodiment, the fastener 630 is a standard bolt fastener.

[0046] The protrusion 626 is typically positioned in the middle of the planar portion 624, such that the protrusion is surrounded on both sides by the planar portion. In the illustrated embodiment, the protrusion 626 includes a generally rectangular or trapezoidal projection including a curved longitudinal edge 632 projecting away from the planar portion 624 and a planar engagement surface 634 between the longitudinal edges. Thus, the planar engagement surface 634 lies in a plane spaced apart from the plane of the planar portion 624 in a direction extending orthogonally to both planes. A hole (not shown) is configured to receive a fastener 640 for attaching the fitting 14 to the attachment device 620. Therefore, the fitting 14 is spaced sufficiently from the web W of the support beam J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 620 in any desired angular orientation. While the protrusion 626 is shown as a rectangular or trapezoidal protrusion, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0047] Additionally, flange 650 extends laterally from the bottom edge of plate member 622 on the opposite side of protrusion 626. Flange 650 provides a mating surface with the lower flange F of support beam J. For this purpose, flange 650 supports attachment device 620 under vertical load conditions. Therefore, the overall size of attachment device 620 is reduced, while the load-bearing capacity of the attachment device is increased.

[0048] The attachment device 620 can be considered as the first attachment device and is configured for attachment to the first surface of the web W of the joist J. See also Figure 13 The second attachment device 620A is configured to be attached to the opposite face of the web W of the support beam J. When the fastener 630 is inserted through the fastener hole in the first attachment device 620, the fastener will pass through the web W of the support beam J and enter the fastener hole in the second attachment device 620A.

[0049] See Figure 14An eighth embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 720. The attachment device 720 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting 14 for attachment to a suitable anti-sway support constraint 10, etc. The attachment device 720 includes a body or plate member 722 configured to attach to the web W of the I-beam J. The plate member 722 has a planar portion 624 and a protruding portion 726. The planar portion 724 provides a contact surface for engaging the web W of the I-beam J. In the illustrated embodiment, the attachment device 720, and especially the plate member 722, has a generally rectangular shape. However, without departing from the scope of this disclosure, the attachment device 720 may be formed in any suitable shape, such as circular or elliptical. Fastener holes (not shown) in the plate member 722 are configured to receive fasteners 730 for securing the attachment device 720 to the web W of the I-beam J. In one implementation, fastener 730 is a torque-shear type nut / bolt fastener used for visual verification of the desired torque to be applied.

[0050] The protrusion 726 is typically positioned in the middle of the planar portion 724, such that the protrusion is surrounded on both sides by the planar portion. In the illustrated embodiment, the protrusion 726 includes a generally trapezoidal projection comprising a longitudinal planar edge 732 projecting at an angle away from the planar portion 724 and a planar engagement surface 734 between the longitudinal edges. Thus, the planar engagement surface 734 lies in a plane spaced apart from the plane of the planar portion 724 in a direction extending orthogonally to both planes. A hole (not shown) is configured to receive a fastener 740 for attaching the fitting 14 to the attachment device 720. Therefore, the fitting 14 is spaced sufficiently from the web W of the joist J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 720 at any desired angular orientation. The fitting 14 can also be attached to the attachment device 720 without creating a through-hole in the web W of the joist J. Although the protrusion 726 is shown as a trapezoidal protrusion, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0051] The attachment device 720 can be considered a first attachment device and is configured to be attached to a first surface of the web W of the joist J. The second attachment device 720A is configured to be attached to the opposite surface of the web W of the joist J. When a fastener 730 is inserted through a fastener hole in the first attachment device 720, the fastener will pass through the web W of the joist J and enter the fastener hole in the second attachment device 720A.

[0052] See Figure 15 and Figure 15AA ninth embodiment of the attachment device for attachment to a structural component is generally indicated by reference numeral 820. The attachment device 820 is configured to attach to a structural component (such as a wooden I-beam J) and to a connecting fitting 14 for attachment to a suitable anti-sway support restraint 10, etc. The attachment device 820 includes a body or plate member 822 configured to attach to the I-beam J. The plate member 822 has a first planar portion 824, a protrusion 826 extending from the first planar portion, a second planar portion 825 extending from the protrusion, a third planar portion 827 extending from the second planar portion 825, a fourth planar portion 829 extending from the third planar portion, a fifth planar portion 831 extending from the fourth planar portion, and a sixth planar portion 833 extending from the fifth planar portion. The first planar portion 824 and the second planar portion 825 provide contact surfaces for engaging the web W of the I-beam J. The third planar portion 827 extends orthogonally to the second planar portion 825 and provides a contact surface for the top of the lower flange F of the support beam J. The fourth planar portion 829 extends orthogonally to the third planar portion 825 and provides a contact surface for the side edge of the lower flange F of the support beam J. The fifth planar portion 831 extends orthogonally to the fourth planar portion 829 and provides a contact surface for the bottom of the lower flange F of the support beam J. The sixth planar portion 833 extends orthogonally to the fifth planar portion 831. A fastener hole (not shown) in the sixth planar portion 833 is configured to receive a fastener 830 for securing the attachment device 820 to the support beam J. In one embodiment, the fastener 830 is a torque-shear bolt for visual verification of the desired torque to be applied.

[0053] A protrusion 826 is typically positioned between the first planar portion 824 and the second planar portion 825, such that the protrusion is surrounded on both sides by the planar portions. In an illustrated embodiment, the protrusion 826 includes a trapezoidal projection comprising a longitudinal planar edge 832 projecting at an angle away from the planar portions 824 and 825, and a mating surface 834 of the plane between the longitudinal edges. Thus, the mating surface 834 of the plane lies in a plane spaced apart from the planes of the first planar portion 824 and the second planar portion 825 in a direction extending orthogonally to these two planes. A hole (not shown) is configured to receive a fastener 840 for attaching the fitting 14 to the attachment device 820. Therefore, the fitting 14 is spaced sufficiently from the web W of the joist J to prevent engagement with the flange F. This allows the fitting 14 to be attached to the attachment device 820 at any desired angular orientation. The fitting 14 can also be attached to the attachment device 820 without creating a through-hole in the web W of the joist J. Although the protrusion 826 is shown as a trapezoidal protrusion, it should be understood that the protrusion may have other configurations without departing from the scope of this disclosure.

[0054] The attachment device 820 can be considered a first attachment device and is configured to attach to a first surface of the web W of the joist J. A second attachment device 820A is configured to attach to the opposite surface of the web W of the joist J. The second attachment device 820A includes a plate member 822A, which includes a first planar portion 825A, a second planar portion 827A extending from the first planar portion 825A, a third planar portion 829A extending from the second planar portion, a fourth planar portion 831A extending from the third planar portion, and a fifth planar portion 833A extending from the fourth planar portion. The first planar portion 825A provides a contact surface for engaging the web W of the joist J. The second planar portion 827A extends orthogonally to the first planar portion 825A and provides a contact surface for the top of the lower flange F of the joist J. The third planar portion 829A extends orthogonally to the second planar portion 825A and provides a contact surface for the side edge of the lower flange F of the joist J. The fourth planar portion 831A extends orthogonally to the third planar portion 829A and provides a contact surface for the bottom of the lower flange F of the support beam J. The fifth planar portion 833A extends orthogonally to the fourth planar portion 831A. Fastener holes (not shown) in the fifth planar portion 833A are configured to receive fasteners 830 for securing two attachment devices 820, 820A to the support beam J.

[0055] See Figure 16 A tenth embodiment of the attachment device for attaching to a structural component is generally indicated by reference numeral 920. The attachment device 920 is substantially the same as the attachment device 720 and includes a flange 950 extending laterally from the bottom edge of the plate member 922 on the opposite side of the protrusion 926. The flange 950 provides a mating surface with the lower flange F of the support beam J. For this purpose, the flange 950 supports the attachment device 920 under vertical load conditions. Therefore, the overall size of the attachment device 920 is reduced, while the load-bearing capacity of the attachment device is increased.

[0056] See Figure 17 An eleventh embodiment of the attachment device for attaching to a structural component is generally indicated by reference numeral 1020. The attachment device 1020 is substantially the same as the attachment device 720. The second attachment device 1020A includes a plate member 1022A and a flange 1050A extending laterally from the bottom edge of the plate member 1022A. The flange 1050A provides a mating surface with the lower flange F of the support beam J. For this purpose, the flange 1050A supports the attachment device 1020A under vertical load conditions. Therefore, the overall size of the attachment device 1020A is reduced, while the load-bearing capacity of the attachment device is increased.
