FIG. 20A shows a header beam 515 being connected to two plus part 503 and center rod 502 combinations (i.e., two “leg sections”) according to some embodiments of the present disclosure. FIG. 20B shows a front view of the header beam 515 connected to the two plus part 503 and center rod 502 combinations according to some embodiments of the present disclosure. Each of the plus part 503 and center rod 502 combinations is the same as the setup from FIGS. 19A-19B and contains two sets of brackets 509 and bracket mirrors 510 connected on left and right sides of the plus part 503. In addition, there is a header plate 511 and rod header 512. Essentially, FIG. 20A shows how two of the combinations are used to continue constructing a sidewalk shed section 500. The header beam 515 includes sets of holes 516 and 517 on either side. In some embodiments, each set 516 and 517 includes three holes, although this is not intended to be limiting and any number of holes could be used. Each of the holes is sized to receive a rod header 512. With this in mind, the plus part 503 and center rod 502 combinations can be spaced from each other such that the header beam 515 can be placed onto said combinations and each rod header 512 is received by a hole of 516 and 517, respectively, securing the header beam 515. In some embodiments, the rod header 512 is substantially the same length as the holes (and thus the height of the header beam 515). In addition, as shown in FIG. 20B, the header beam 515 rests on each of the header plates 511 for additional support, both in the vertical and horizontal directions. In addition, the bracket 509 and bracket mirror 510 protrude substantially perpendicularly from the header beam 515, defining a corner and allowing for connections to additional configurations (discussed below in relation to FIGS. 21A-21F).
FIGS. 21A-21F shows two senior beams 519 being connected to various plus part 503 and center rod 502 combinations according to some embodiments of the present disclosure. Senior beams 519 are used to connect two of the configurations shown in FIGS. 20A and 20B above. As discussed above, the bracket configuration 518, which is comprised of a bracket 509 and a bracket mirror 510, protrudes substantially perpendicularly from the header beam 515, defining a corner. Multiple corners can thus be connected via a senior beam 519. Each bracket configuration 518 is configured to receive a senior beam 519. In some embodiments, the width of the bracket configuration 518 is slightly larger than the senior beam 519 to allow for a snug fit. In addition, various holes on either side of the senior beam 519 can align with the set of two holes on either side of the bracket configuration 518 (see FIG. 21B). The senior beams 519 can then be secured to the bracket configurations 518 via a senior pin plate 520 and locker 521 (see FIG. 21C). Pins from the senior pin plate 520 are inserted through the aligned holes of the bracket configuration 518 and senior beam 519 and secured via the locker 521. In FIG. 21D, various clamps 522 are attached to the underside of the senior beams 519 (e.g., two clamps 522 are attached to each senior beam 519). Each of the clamps 522 includes two holes that can align with sets of two holes on the senior beam 519. Then, as shown in FIG. 21E, a brace 504 can be connected to the plus part 503 at one end and the clamp 522 at an opposite end. In some embodiments, the brace 504 connections can be made via a bracing cap 527, as discussed in relation to FIG. 8. A bracing cap 527 can be received at each end of the brace 504, and the free ends of the bracing cap 527 can be attached to a hole on the plus part 503 and the clamp 522, respectively. The attachments can then be secured via a pin. In addition, in the adjacent side, the brace 504 is connected (similarly, via a bracing cap 527) to the underside of the header beam 515. FIG. 21F shows a front view of the configuration. Each brace 504 is connected via bracing caps 527 to the clamp 522 of the senior beam 519 at one end and the plus part 503 at an opposite end, providing support to the senior beam 519.
