[0046] For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings and specific language will be used to describe the same.

[0047] A scaffold system 2 configured to support workers above ground on the outside of a building or other structure is shown in FIG. 1. The scaffold system 2 allows the workers to build, repair, clean, etc. the building or other structure. The scaffold system 2 includes a beam assembly 4 in accordance with the present disclosure, a plurality of work platforms 6, and a post and ledger system 8. The beam assembly 4 is configured to provide structural support for the scaffold system 2. The plurality of work platforms 6 are coupled with the beam assembly 4 to provide a generally planar work surface on each level of the scaffold system 2 upon which the workers may stand and rest tools and equipment. The rail system 8 is coupled with the beam assembly 4 and provides vertical support for the different floors of the scaffold system 2 and may help to block workers and equipment from falling from the scaffold system 2.

[0048] The beam assembly 4 includes a plurality of support beams 10 and one or more of and any combination of a number of connection components as suggested in FIGS. 1-27. The additional connection components include, but are not limited to, joining beams 60, 60, a ringlock ledger connector 110, an upper scaffold post connector 210, a lower scaffold post connector 310, guardrail posts 410, 410, an angle bracket 510, and an anchor bracket 610. The beam assembly 4, with its number of interconnecting components, allows for modular and customizable configurations for the scaffold system 2.

[0049] Each support beam 10 extends axially relative to an axis 11 and includes an upper attachment mount 12, a lower attachment mount 14, a web member 16, and a top rail 18 as shown in FIG. 2. The upper attachment mount 12, lower attachment mount 14, and web member 16 cooperate to provide structural strength to the support beam 10. The upper attachment mount 12, lower attachment mount 14, and web member 16 are shaped generally as an I-beam in cross section. The top rail 18 extends away from the upper attachment mount 12 and configured to couple with and support the work platforms 6 as suggested in FIG. 5. In the illustrative embodiment, the upper attachment mount 12, lower attachment mount 14, web member 16, and top rail 18 are integrally formed as a single, one-piece beam. As shown in FIGS. 2-4, the features of the support beam 10 are symmetrical about a vertical axis.

[0050] The upper attachment mount 12 extends axially relative to the axis 11 and is generally rectangular as shown in FIGS. 2-4. The upper attachment mount 12 includes a plurality of first through holes 22 that extend completely through the upper attachment mount 12 in a transverse direction perpendicular to the axis 11. The plurality of first through holes 22 are configured to receive fasteners 15 such as, for example, pins, bolts, etc. that extend through the upper attachment mount 12 and another component to couple the component with the support beam 10.

[0051] The plurality of first through holes 22 each have a same first diameter. Each of the plurality of first through holes 22 are spaced apart axially relative to one another. Each of the plurality of first through holes 22 are located at a same vertical height relative to a bottom of the support beam 10 and relative to the top of the support beam 10 such that the plurality of first through holes 22 are arranged generally along a line. Each of the plurality of first through holes 22 are circular in the illustrative embodiment.

[0052] The upper attachment mount 12 includes a first upper sidewall 24, a second upper sidewall 26, and a top wall 28 as shown in FIG. 2. The first upper sidewall 24 and the second upper sidewall 26 are spaced apart from one another and extend vertically as well as axially along a length of the support beam 10. The first upper sidewall 24 and the second upper sidewall 26 are parallel with each other. The plurality of first through holes 22 extend through the first upper sidewall 24 and the second upper sidewall 26. The top wall 28 extends between and interconnects the first upper sidewall 24 and the second upper sidewall 26.

[0053] The lower attachment mount 14 extends axially relative to the axis 11 and is generally rectangular as shown in FIGS. 2-4. The lower attachment mount 14 includes a plurality of second through holes 30 that extend completely through the lower attachment mount 14 in a transverse direction perpendicular to the axis 11. The plurality of second through holes 30 each have a same second diameter. The plurality of second through holes 30 are configured to receive fasteners 15 such as, for example, pins, bolts, etc. that extend through the lower attachment mount 14 and another component to couple the component with the support beam 10.

[0054] Each of the plurality of second through holes 30 are spaced apart axially relative to one another. Each of the plurality of second through holes 30 are located at a same vertical height relative to a bottom of the support beam 10 and relative to the top of the support beam 10 such that the plurality of second through holes 22 are arranged generally along a line. The second diameter is equal to the first diameter in the illustrative embodiment such that the same type of fasteners may be used with the upper attachment mount 12 and the lower attachment mount 14. Each of the plurality of second through holes 30 are circular in the illustrative embodiment.

[0055] The lower attachment mount 14 includes a first lower sidewall 32, a second lower sidewall 34, and a bottom wall 36 as shown in FIG. 2. The first lower sidewall 32 and the second lower sidewall 34 are spaced apart from one another and extend vertically as well as axially along a length of the support beam 10. The first lower sidewall 32 and the second lower sidewall 34 are parallel with each other. The plurality of second through holes 30 extend through the first lower sidewall 32 and the second lower sidewall 34. The bottom wall 36 extends between and interconnects the first lower sidewall 32 and the second lower sidewall 34.

[0056] The bottom wall 36 is formed to define a T-bolt slot 38 configured to receive T-bolts as shown in FIG. 2. The T-bolt slot 38 extends axially along the length of the support beam 10 and opens downwardly away from upper attachment mount 12 through a lowermost face of the bottom wall 36. The lowermost face of the bottom wall 36 is planar. In the illustrative embodiment, the first upper sidewall 24, second upper sidewall 26, top wall 28, first lower sidewall 32, second lower sidewall 34, bottom wall 36, first wall 42, and second wall 44 are each generally planar.

[0057] The web member 16 extends between and interconnects the upper attachment mount 12 and the lower attachment mount 14 as shown in FIGS. 2-4. The web member 16 is formed to define a plurality of third through holes 40 that extend completely through the web member 16 in a transverse direction perpendicular to the axis 11. The plurality of third through holes 40 each have a same third diameter. The plurality of third through holes 40 are configured to receive components that couple with the support beam 10 such as, for example, ringlock ledger connector 110.

[0058] Each of the plurality of third through holes 40 are spaced apart axially relative to one another. Each of the plurality of third through holes 40 are located at a same vertical height relative to a bottom of the support beam 10 and relative to the top of the support beam 10 such that the plurality of third through holes 40 are arranged generally along a line. The third diameter is at least three times larger than the first diameter and the second diameter in the illustrative embodiment. Each of the plurality of third through holes 40 are circular in the illustrative embodiment. Each of the plurality of third through holes 40 are spaced vertically about halfway between the upper attachment mount 12 and the lower attachment mount 14. Each of the plurality of third through holes 40 are spaced apart axially from one another a distance equal to about the third diameter. One half of a third through hole 40 is formed in each of the axially terminating ends of the web member 16.

[0059] The web member 16 includes a first wall 42 and a second wall 44 spaced apart from the first wall 42 as shown in FIG. 2. The first wall 42 and the second wall 44 are generally parallel with each other. The first wall 42 extends between and interconnects the first upper sidewall 24 and the first lower sidewall 32. The second wall 44 extends between and interconnects the second upper sidewall 26 and the second lower sidewall 34. The plurality of third through holes 40 extend through the first wall 42 and the second wall 44.

[0060] The web member 16 is situated inward of the upper attachment mount 12 and the lower attachment mount 14 as shown in FIGS. 2-4. This forms a channel on each side of the support beam 10 that extend axially along the support beam 10. The first wall 42 is spaced apart transversely inward toward center from the first upper sidewall 24 and the first lower sidewall 32. The second wall 44 is spaced apart transversely inward toward center from the second upper sidewall 26 and the second lower sidewall 34. In other words, a distance between the first upper sidewall 24 and the second upper sidewall 26 is greater than a distance between the first wall 42 and the second wall 44.

[0061] The upper attachment mount 12, the lower attachment mount 14, and the web member 16 cooperate to define a passage 46 that extends axially completely through the support beam 10 as suggested in FIGS. 2-4. As such, the support beam 10 is hollow within the upper attachment mount 12, the lower attachment mount 14, and the web member 16. In the illustrative embodiment, the first upper sidewall 24, second upper sidewall 26, top wall 28, first lower sidewall 32, second lower sidewall 34, bottom wall 36, first wall 42, and second wall 44 define the perimeter of the passage 46. As suggested in FIGS. 2-4, the passage 46 is sized to receive the entire joining beam 60 therein.

[0062] The top rail 18 extends vertically away from the top wall 28 of the upper attachment mount 12 as shown in FIGS. 2-4. The top rail 18 includes a stem 48 and a head 50 coupled with the stem 48. The stem 48 extends vertically away from the top wall 28 of the upper attachment mount 12. The stem 48 extends the axial length of the support beam 10. The stem 48 is centered in the transverse direction on the axis 11 such that it is located about midway between the first upper sidewall 24 and the second upper sidewall 26.

[0063] The head 50 extends transversally outward from the stem 48 and vertically outward from the stem 48 as shown in FIGS. 2-4. The head 50 includes an uppermost surface that is planar. The head 50 is formed to define a T-bolt slot 52 that extends into the head 50 and opens outwardly from the uppermost surface. In the illustrative embodiment, the head 50 is D-shaped when viewed axially relative to the axis 11. Illustratively, the head 50 is formed to define a cavity that extends axially through the head 50 such that the head 50 is hollow.

[0064] The head 50 includes top wall 54, a first sidewall 56, and a second sidewall 58 as shown in FIGS. 2-5. The top wall 54 is formed to define the T-bolt slot 52 and interconnects the first sidewall 56 and the second sidewall 58. The top wall 54 has a lateral width 55 equal to or about equal to 48.3 millimeters. In other words, the lateral width 55 of the top wall 54 is about equal to the outside diameter of a conventional scaffold tube. Having the lateral width 55 be about equal with the outside diameter of a conventional scaffold tube allows the beam hooks 74, 76 of pre-existing work platforms 6 to function with both the beam assembly 4 of the present disclosure and with conventional scaffold tube scaffolding systems. For example, the beam hooks 74, 76 of the work platforms 6 may couple with the head 50 of the support beam 10 or, if using a conventional scaffold system, the work platforms 6 may couple with conventional scaffold tubes.

[0065] The first sidewall 56 includes a planar segment coupled with the top wall 54 and a curved segment that extends from the planar segment to the stem 48. The second sidewall 58 includes a planar segment coupled with the top wall 54 and a curved segment that extends from the planar segment to the stem 48. As discussed in greater detail below, the stem 48 and the head 50 are configured to engage and support the work platforms 6 as shown in FIGS. 5 and 6.

[0066] The plurality of work platforms 6 are supported across pairs of support beams 10 as suggested in FIGS. 1, 5, and 6. Each work platform 6 includes a platform body 73, a first beam hook 74, a second beam hook 76, and, illustratively, a first lock tab 78 and a second lock tab 80 as shown in FIG. 5. FIG. 6 shows the scaffold system 2 similar to FIG. 1, but with an alternative post and ledger system 8.

[0067] The platform body 73 extends between and is supported on the top walls 54 of the heads 50 of the corresponding pair of support beams 10 a shown in FIG. 5. The first beam hook 74 is coupled to a terminal end of the platform body 73 and extends over the top wall 54 and first sidewall 56 of the head 50 to block movement of the work platform relative to a first of the support beams 10. The second beam hook 76 is coupled to the other terminal end of the platform body 73 and extends over the top wall 54 and second sidewall 58 of the head 50 to block movement of the work platform relative to a second of the support beams 10. The first and second beam hooks 74, 76 are sized and arranged to allow work platforms 6 to be placed on each side of a support beam 10 to make continuous work surface on each side of the support beam 10 as shown in FIG. 1.

[0068] The first lock tab 78 is rotatably coupled with the platform body 73 and configured to interlock the work platform 6 with the first support beam 10 as suggested in FIG. 5. A first end of the first lock tab 78 is coupled to a pin of the platform body 73 and formed with a slot that allows the first lock tab 78 to rotate and slide relative to the pin. A second end of the first lock tab 78 is configured to extend into a space defined between the second sidewall 58 of the head 50 and the top wall 28 of the upper attachment mount 12. The first lock tab 78 and the first beam hook 74 cooperate to block the work platform 6 from fully uncoupling from the first support beam 10. The second lock tab 80 is substantially similar to the first lock tab 78 and is spaced apart from the first lock tab 78 to interact with the second support beam 10.

[0069] The joining beam 60 is configured to join one support beam 10 to another component and, typically, to another support beam 10 as suggested in FIGS. 2-4. A first end of the joining beam 60 is configured to be received in and slide axially in the passage 46 formed in the support beam 10. The fasteners 15 extend through the support beam 10 and the joining beam 60 to couple the joining beam 60 with the support beam 10 (or other component configured to receive the joining beam 60). A second end of the joining beam 60 may be received in a second support beam 10 and fasteners inserted therethrough to couple the joining beam 60 with the second support beam and, therefore, couple one support beam 10 to another support beam 10.

[0070] The joining beam 60 includes an upper flange 62, a lower flange 64, and a web 66 that each extend an axial length of the joining beam 60 as suggested in FIGS. 2-4. The upper flange 62 is configured to be received within the upper attachment mount 12 and to receive the fasteners 15 that extend through the upper attachment mount 12. The lower flange 64 is configured to be received within the lower attachment mount 14 and to receive the fasteners 15 that extend through the upper attachment mount 12. The web 66 extends vertically and interconnects the upper flange 62 and the lower flange 64. The web 66 is configured to be received within the web member 16 and to receive the components, such as ringlock ledger connector 110, that extend through the web member 16.

[0071] The upper flange 62 is rectangular when viewed axially and is hollow as shown in FIG. 2. The upper flange 62 is formed to define a plurality of first joining beam through holes 68 that extend transversally to the axis 11 through the upper flange 62.

[0072] The plurality of first joining beam through holes 68 each have a same first joining beam diameter. The first joining beam diameter is equal to or about equal to the first diameter of the first through holes 22 formed in the upper attachment mount 12. The first joining beam diameter may be nominally larger than the first diameter to make it easier to pass the fasteners 15 through the first joining beam through holes 68.

[0073] Each of the plurality of first joining beam through holes 68 are spaced apart axially relative to one another with the same axial spacing as the first through holes 22 formed in the upper attachment mount 12. Each of the plurality of first joining beam through holes 68 are located at a same vertical height relative to a bottom of the joining beam 60 and relative to the top of the joining beam 60 such that the plurality of first joining beam through holes 68 are arranged generally along a line. Each of the plurality of first joining beam through holes 68 are circular in the illustrative embodiment.

[0074] The lower flange 64 is rectangular when viewed axially and is hollow as shown in FIG. 2. The lower flange 64 is formed to define a plurality of second joining beam through holes 70 that extend transversally to the axis 11 through the lower flange 64. The plurality of second joining beam through holes 70 each have a same second joining beam diameter. The second joining beam diameter is equal to or about equal to the second diameter of the second through holes 30 formed in the lower attachment mount 14. The second joining beam diameter may be nominally larger than the second diameter to make it easier to pass the fasteners 15 through the second joining beam through holes 70.

[0075] Each of the plurality of second joining beam through holes 70 are spaced apart axially relative to one another with the same axial spacing as the second through holes 30 formed in the lower attachment mount 14. Each of the plurality of second joining beam through holes 70 are located at a same vertical height relative to a bottom of the joining beam 60 and relative to the top of the joining beam 60 such that the plurality of second joining beam through holes 70 are arranged generally along a line. Each of the plurality of second joining beam through holes 70 are circular in the illustrative embodiment.

[0076] The web 66 is formed to define a plurality of third joining beam through holes 72 that extend completely through the web 66 in a transverse direction perpendicular to the axis 11 as shown in FIGS. 2-4. The plurality of third joining beam through holes 72 each have a same third joining beam diameter. The third joining beam diameter is equal to or about equal to the third diameter of the third through holes 40 formed in the web member 16. The third joining beam diameter may be nominally larger than the third diameter to make it easier to pass fastening features through the third joining beam through holes 72. The plurality of third joining beam through holes 72 are configured to receive components that couple with the support beam 10 such as, for example, the ringlock ledger connector 110. The web 66 is situated inward of the upper flange 62 and the lower flange 64 as shown in FIGS. 2-4. This forms a channel on each side of the joining beam 60 that extend axially along the joining beam 60.

[0077] Each of the plurality of third joining beam through holes 72 are spaced apart axially relative to one another by the same spacing as the third through holes 40. Each of the plurality of third joining beam through holes 72 are located at a same vertical height relative to a bottom of the joining beam 60 and relative to the top of the joining beam 60 such that the plurality of third joining beam through holes 72 are arranged generally along a line. The third joining beam diameter is at least two times larger than the first joining beam diameter and the second joining beam diameter in the illustrative embodiment. Each of the plurality of third joining beam through holes 72 are circular in the illustrative embodiment. One half of a third joining beam through hole 72 is formed in each of the axially terminating ends of the web 66.

[0078] The ringlock ledger connector 110 is configured to couple a first support beam 10 to a second support beam 10 spaced apart transversally from the first support beam as suggested in FIGS. 7-15. The ringlock ledger connector 110 may also couple a first support beam 10 to another component other than another support beam 10 located adjacent the first support beam 10. In some embodiments, a first ringlock ledger connector 110 is coupled with the first support beam 10, a second ringlock ledger connector 110 is coupled with the second support beam 10, and a scaffold ledger 90 extends between and interconnects the first ringlock ledger connector 110 and the second ringlock ledger connector 110 as shown in FIGS. 9-12. In some embodiments, a first ringlock ledger connector 110 is coupled with the first support beam 10, a second ringlock ledger connector 110 is coupled with the second support beam 10, and a ledger 90 with minimal length extends between and interconnects the first ringlock ledger connector 110 and the second ringlock ledger connector 110 as shown in FIGS. 14-15.

[0079] Each ringlock ledger connector 110 includes a ringlock connector 112, a first lock plate 114, and a second lock plate 116 as show in FIGS. 7 and 8. The ringlock connector 112 is configured to couple with ledgers 90 or other components. The first lock plate 114 and the second lock plate 116 cooperate to couple the ringlock connector 112 with the support beam 10 as suggested in FIGS. 9 and 11.

[0080] The ringlock connector 112 includes a centerbody 120, a first connection plate 122, and a second connection plate 124 as shown in FIGS. 7 and 8. The centerbody 120 is cylindrical in the illustrative embodiment and sized with a diameter to be received in the third through holes 40 formed in the web member 16 of the support beam 10 and the third joining beam through holes 68 of the joining beam 60. As such, the centerbody 120 has a diameter nominally smaller than the third joining beam hole diameter in the illustrative embodiment. The centerbody 120 is completely solid in the illustrative embodiment. The centerbody 120 has a width greater than a width between the first wall 42 and the second wall 44 of the web member 16.

[0081] The first connection plate 122 is fixed with the centerbody 120 and extends away from the centerbody 120 along a transverse axis 111 that is perpendicular with the axis 11 of the support beam 10 as shown in FIG. 7. The first connection plate 122 has a cuboid shape in the embodiment shown. The first connection plate 122 has a relatively small height compared to its length and width as shown in FIG. 7. The first connection plate 122 is located along a center point of the centerbody 120. The first connection plate 122 is formed to define a first aperture 126 that extends entirely through the first connection plate 122 to receive a wedge 96 of a ledger 90 as suggested in FIGS. 9-12. The first aperture 126 has elongated curved walls and two planar endwalls connecting the curved walls. The first aperture 126 is generally centered in the first connection plate 122.

[0082] The second connection plate 124 is substantially similar to the first connection plate 122. The second connection plate 124 extends from the opposite end of the centerbody 120 away from the first connection plate 122. The second connection plate 124 is formed to define a second aperture 128 that extends entirely through the second connection plate 124. The second connection plate 124 and the first connection plate 122 are oriented in substantially the same plane and are parallel with each other.

[0083] The first lock plate 114 is configured to engage the support beam 10 and block the ringlock ledger connector 110 from passing through or rotating relative to the support beam 10 as suggested in FIG. 9. The first lock plate 114 is fixed with at least one of the centerbody 120 and the first connection plate 122. In other embodiments, the first lock plate 114 is configured to slide on and off the ringlock connector 112. The first lock plate 114 extends outward beyond the centerbody 120 across 360 degrees when viewed along the transverse axis 111. The first lock plate 114 is rectangular when viewed along the transverse axis 111 in the illustrative embodiment. The first lock plate 114 has four planar perimeter surfaces and, in the exemplar embodiment, are each interconnected by rounded edges. The first lock plate 114 is formed to define a slot 130 that extends axially entirely through the first lock plate 114. The first connection plate 122 extends through the slot 130 and the first lock plate 114 abuts the centerbody 120.

[0084] The first connection plate 122 has a first segment 132, a second segment 134, and a third segment 136 as shown in FIG. 7. The first segment 132 is generally planar and the second segment 134 is generally planar. The third segment 136 extends between and interconnects the first segment 132 and the second segment 134. The third segment 136 is curvilinear such that a concave opening faces the centerbody 120. The contour of the third segment 136 matches the curved contour of a scaffold tube 86 of a post 84.

[0085] The second lock plate 116 is substantially similar to the first lock plate 114 as suggested in FIG. 7. The second lock plate 116 is configured to removably couple with the ringlock connector 112 as suggested in FIGS. 7 and 8. The second lock plate 116 is formed to define a slot 138 that extends axially entirely through the second lock plate 116. The second connection plate 124 extends through the slot 138 and the second lock plate 116 is configured to removably engage the centerbody 120. The second lock plate 116 includes a first segment 140, a second segment 142, and a third segment 146 that interconnects the first segment 140 and the second segment 142. The first and second segments 140, 142 are planar and the third segment 146 is curved similar to the third segment 136.

[0086] In use, the second lock plate 116 is separated from the ringlock connector 112 and the centerbody 120 is inserted into one of the third through holes 40 formed in the web member 16 of the support beam 10 (and through a third joining beam through hole 68 if a joining beam 60 is in its path) as suggested in FIGS. 9, 10, 14, and 15. The centerbody 120 is located in the third hole 40, the first lock plate 114 abuts the second wall 44 of the web member 16, and the second connection plate 124 extends away from the first wall 42. The first lock plate 114 blocks the ringlock connector 112 from moving through and escaping the third through hole 40.

[0087] The second lock plate 116 is slid over the second connection plate 122 such that the second connection plate 122 extends through the slot 138 formed in the second lock plate 116 as shown in FIG. 9. The second lock plate 116 is located within the channel formed by the support beam 10 and engages the first wall 42 of the web member 16.

[0088] A ledger 90 is moved to the ringlock ledger connector 110 and the support beam 10 as suggested in FIG. 9. Each ledger 90 includes an elongated support body 92, a first ledger head 94 and a second ledger head 95 coupled to opposite ends of the elongate support body 92, and wedges 96 configured to be received by the ledger heads 94, 95. The wedge 96 is removed from the first ledger head 94 and the ledger 90 is moved such that the second lock plate 116 extends into the first ledger head 94 as suggested in FIGS. 9 and 10. The wedge 96 is moved through the ledger head 94 and the aperture 128 formed in the second connection plate 124 to interlock the ledger 90 with the ringlock ledger connector 110 as shown in FIG. 10. The wedge 96 removably couples the ledger 90 with the ringlock ledger connector 110 and support beam 10. The interlocking of the wedge 96 in the aperture 128 of the second connection plate 124 blocks the second lock plate 116 from uncoupling from the ringlock connector 112.

[0089] The first lock plate 114 is fixed with the ringlock connector 112 in the illustrative embodiment. As such, a second leger 90 may or may not be coupled with the first connection plate 122 of the ringlock ledger connector 110 and the ringlock ledger connector 110 will still stay coupled with the support beam 10 due to the wedge 96 extending through the second connection plate 124. In other embodiments, the first lock plate 114 may be removably coupled with the ringlock connector 112 such that a second ledger 90 is used to secure the ringlock ledger connector 110 with the support beam 10.

[0090] The first lock plate 114 and the second lock plate 116 are sized and shaped to block rotation of the ringlock ledger connector 110 in the third hole 40 as suggested in FIGS. 9 and 10. The centerbody 120 is cylindrical and may be urged to rotate within the circular third through holes 40. Because the lock plates 114, 116 are located within the channels of the support beam 10, the perimeter surfaces of the lock plates 114, 116 are configured to rotate with the ringlock connector 112 and engage the upper attachment mount 12 and the lower attachment mount 14 which blocks the ringlock ledger connector 110 from rotating. The lock plates 114, 116 are sized nominally smaller than the channel height such that minimal rotation occurs before the ringlock ledger connector 110 engages the support beam and is blocked from rotating.

[0091] As shown in FIGS. 11 and 12, the ringlock ledger connector 110 may also be coupled with the support beam 10 with the first connection plate 122 and the second connection plate 124 extending horizontally and the wedge 96 extending vertically. Each lock plate 114, 116 is generally square shaped to allow insertion into the channel at 90 degree rotations. The other end of the leger 90 may coupled with a second support beam 10 or other component.

[0092] Two support beam 10 may be coupled together with a small transverse distance therebetween using ringlock ledger connectors 110 and short or modified ledgers 90 as shown in FIGS. 13-15. As shown in FIGS. 13 and 14, two ringlock ledger connectors 110 are coupled with a first support beam 10 and spaced apart from each other by an axial distance. Two more ringlock ledger connectors 110 are coupled with a second support beam 10 and spaced apart from each other by the same axial distance. A first short ledger 90 with ledger heads 94, 95 interconnect two of the ringlock ledger connectors 110 and a second short ledger 90 with ledger heads 94, 95 interconnect the other two of the ringlock ledger connectors 110.

[0093] The upper scaffold post connector 210 and the lower scaffold post connector 310 are shown in FIGS. 16-19. The upper scaffold post connector 210 and the lower scaffold post connector 310 are configured to couple the support beam 10 with upright posts 84 as suggested in FIGS. 1 and 6. The upper scaffold post connector 210 couple to and extend upward from the upper attachment mounts 12 of the support beam 10 as shown in FIGS. 16 and 17. The lower scaffold post connector 310 couple to and extend downward from the lower attachment mounts 14 of the support beam 10 as shown in FIGS. 18 and 19.

[0094] The upper scaffold post connector 210 includes a beam connector 212 configured to couple with the upper attachment mount 12 of the support beam 10 and a post coupler 214 as shown in FIGS. 16 and 17. The beam connector 212 removably couples the upper scaffold post connector 210 with the support beam 10. The post coupler 214 extends vertically away from the beam connector 212 and is configured to couple the upper scaffold post connector 210 with an upright post 84 as suggested in FIGS. 1 and 6.

[0095] The beam connector 212 includes a mount plate 220, a first flange 222, a second flange 224, and a plurality of support ribs 226 as shown in FIGS. 16 and 17. The mount plate 220 is planar and sized to extend transversely over and beyond the edges of the top rail 18 of the support beam 10. The first flange 222 and the second flange 224 extend downwardly away from the mount plate 220 on opposite sides of the support beam 10 and receive fasteners 15 for coupling the beam connector 212 with the support beam 10. The support ribs 226 are coupled with the mount plate 220 and one of the first flange 222 and the second flange 224 to reinforce the beam connector 212.

[0096] The first flange 222 is formed to define at least one hole 228 that extends through the first flange 222 as shown in FIGS. 16 and 17. The at least one hole 228 is configured to align with one of the first through holes 22 formed in the upper attachment mount. In the illustrative embodiment, the at least one hole 228 includes two holes 228. The two holes 228 are spaced apart from each other axially relative to the axis 11 with the same axial spacing as the first through holes 22. As such, each of the holes 228 aligns with one of the first through holes 22.

[0097] The illustrative first flange 222 is T-shaped having a first segment with a first width coupled with the mount plate 220 and a second segment having a second width larger than the first width as shown in FIGS. 16 and 17. The first segment is solid with no apertures in the embodiment shown. The second segment is formed to define the holes 228. The second segment is generally planar and engages a sidewall of the upper attachment mount 12. The second segment has a height about equal to the height of the upper attachment mount 12. The first segment is generally planar and extends around the top rail 18 of the support beam so as to join with the mount plate 220 at a location transversely outward of the second segment. Two support ribs 226 having generally triangular shapes are coupled with the mount plate 220 and the first flange 222. The two support ribs 226 terminate partway along the second segment.

[0098] The second flange 224 is substantially similar to the first flange 222 as shown in FIGS. 16 and 17. The second flange 224 is formed to define holes 230 for receiving the fasteners 15.

[0099] The post coupler 214 extends vertically away from the mount plate 220 of the beam connector 212 as shown in FIGS. 16 and 17. The post coupler includes an upright post 232, a scaffold rosette 234, and ribs 236. The upright post 232 is coupled with the mount plate 220 and extends vertically away from the support beam 10. The upright post 232 includes a first segment with a first diameter and a second segment with a second diameter for insertion into another post 84 for example as shown in FIG. 1. The scaffold rosette 234 is fixed with the upright post 232 and configured to receive ledger heads 94, 95 and wedges 96 for coupling ledgers 90 with the upper scaffold post connector 210 as shown in FIG. 1. The ribs 236 extend vertically and coupled to a base of the upright post 232 and the mount plate 220.

[0100] A second embodiment of an upper scaffold post connector 210 is shown in FIG. 6. The upper scaffold post connector 210 is substantially similar to the upper scaffold post connector 210 and includes each of the features of the upper scaffold post connector 210 except where the figures and descriptions of each differ. In particular, the upper scaffold post connector 210 includes a beam connector 212 and a post coupler 214. The post coupler 214 is a stub coupler and is relatively short as opposed to the relative tall post coupler 214. The post coupler 214 does not include a scaffolding rosette.

[0101] The lower scaffold post connector 310 is similar to the upper scaffold post connector 210, but configured to extend downwardly from the lower attachment mount 14 of the support beam as shown FIGS. 18 and 19. The lower scaffold post connector 310 includes a beam connector 312 configured to couple with the lower attachment mount 14 of the support beam 10 and a post coupler 314. The beam connector 312 removably couples the lower scaffold post connector 310 with the support beam 10. The post coupler 314 extends vertically downward and away from the beam connector 312 and is configured to couple the lower scaffold post connector 310 with an upright post 84. In this way, upper levels of support beams 10 and work platforms 6 may be added to the scaffold system 2 and supported by the support beams 10 and upright posts 84 beneath.

[0102] The beam connector 312 includes a mount plate 320, a first flange 322, a second flange 324, and a plurality of support ribs 326 as shown in FIGS. 18 and 19. The mount plate 320 is planar and sized to extend transversely over and beyond the edges of bottom wall 36 of the lower attachment mount 14 of the support beam 10. The first flange 322 and the second flange 324 extend upwardly away from the mount plate 320 on opposite sides of the support beam 10 and receive fasteners 15 for coupling the beam connector 312 with the support beam 10. The support ribs 326 are coupled with the mount plate 320 and one of the first flange 322 and the second flange 324 to reinforce the beam connector 312.

[0103] The first flange 322 is formed to define at least one hole 328 that extends through the first flange 322 as shown in FIGS. 18 and 19. The at least one hole 328 is configured to align with one of the second through holes 30 formed in the lower attachment mount 14. In the illustrative embodiment, the at least one hole 328 includes two holes 328. The two holes 328 are spaced apart from each other axially relative to the axis 11 with the same axial spacing as the second through holes 30. As such, each of the holes 328 aligns with one of the first through holes 30.

[0104] The first flange 322 is generally planar and engages a sidewall of the lower attachment mount 14. The first flange 322 has a height about equal to the height of the lower attachment mount 14. Two support ribs 326 having generally triangular shapes are coupled with the mount plate 320 and the first flange 322. The two support ribs 326 terminate partway along the second segment.

[0105] The second flange 324 is substantially similar to the first flange 322 as shown in FIGS. 18 and 19. The second flange 324 is formed to define holes 330 for receiving the fasteners 15.

[0106] The post coupler 314 extends vertically downward away from the mount plate 320 of the beam connector 312 as shown in FIGS. 18 and 19. The post coupler includes an upright post 332, a scaffold rosette 334, and ribs 336. The upright post 332 is coupled with the mount plate 320 and extends vertically away from the support beam 10. The upright post 332 is configured to receive another post 84. The scaffold rosette 334 is fixed with the upright post 332 and configured to receive ledger heads 94, 95 and wedges 96 for coupling ledgers 90 with the lower scaffold post connector 310. The ribs 336 extend vertically and coupled to a base of the upright post 332 and the mount plate 320.

[0107] As suggested in FIG. 28, one or multiple upper scaffold post connectors 210 and lower scaffold post connectors 310 are configured to couple to the same support beam 10. The spacing between the upper attachment mount 12 and lower attachment mount 14 along with the sizing of the beam connectors 212, 312 allow the upper scaffold post connector 210 and the lower scaffold post connector 310 to be coupled to the same support beam 10 and vertically aligned with one another as suggested in FIG. 28 to allow the upper scaffold post connector 210 and the lower scaffold post connector 310 to support upper and lower levels of the scaffold system 2. The beam connector 212 is configured to be coupled to the upper attachment mount 12 with fasteners 15 and the beam connector 312 is coupled with fasteners 15 to the lower attachment mount 14 of the same support beam 10 directly below and axially aligned with the beam connector 212.

[0108] The guardrail post 410 as shown in FIG. 20A is configured to couple to a terminal end of a support beam 10 to couple an upright post 84 with the support beam 10. The guardrail post 410 includes a joining beam stub 460 and a post coupler 484 fixed with the joining beam stub 460. The joining beam stub 460 is similar to the joining beam 60 and the post coupler 484 is similar to a portion of a scaffolding post 84 and configured to couple with a scaffolding post 84.

[0109] The joining beam stub 460 includes an upper flange 462 having first joining beam stub through holes 468, a lower flange 464 having second joining beam stub through holes 470, and a web 466 having a third joining beam stub through hole 468 as shown in FIG. 20A. The first joining beam stub through holes 468 and the second joining beam stub through holes 470 have diameters and axial spacing equal to the diameters and spacing of joining beam through holes 68, 70. The third joining beam stub through hole 470 has a diameter and axial location relative to the other holes 468, 470 equal to that of the third joining beam through hole 70. In other embodiments, a support beam stub (segment of a support beam 10) may be used in the guardrail post 410 and connected with a support beam 10 via a joining beam 60.

[0110] The post coupler 484 includes a circular tube 486 coupled with an axial terminal end of the joining beam stub 460 as shown in FIG. 20A. A portion of the tube 486 extends below the lower flange 464 and a portion of the tube 486 extends above the upper flange 462.
