Definitions

  • the present application is directed to scaffolding systems and, in particular, to the use of scaffold posts that include ring lock style connections.
  • Figure 1 shows the layout of the Layher ring lock used today.
  • Erectors like the hole layout in the ring.
  • the small holes allow up to 4 ledgers to be connected to the rosette at automatically orientated at 90 degrees from each other. This is achieved by the shape of the small holes which guide the wedge in the correct orientation.
  • the large holes in the rosettes allow up to four braces or additional ledgers to be added at angles of 45 degrees from the adjacent ledgers. These larger holes also allow ledgers to the attached at angles other than 90 or 45 degrees. This can be handy when building a scaffold against the sidewalls of a round tank.
  • the rosette 10 of Figure 1 is based upon the concept of the original Layher-designed rosette. It has the characteristic 4 small holes with larger holes 22 between them.
  • Figure 2 shows the rosette used in the newly launched Monzon scaffold system. It can be seen that the ledgers 30 connected to the large holes have a range of +/-15 degrees from the 45 degree orientation. This limitation in adaptability causes erectors to have to use tube and fittings or try some other way to get the scaffold system to fit the application.
  • ring formats have also been used, though these are rare.
  • One such system is the ALUMA product.
  • the rosette 40 is shown in Figure 3.
  • the 8 large holes allow ledgers to be fitted at angles other than 90 and 45 degrees, but the spoke provide an annoying obstruction.
  • a scaffolding system of the present disclosure has upright members connected to adjacent upright members by releasable ledgers that engage rosettes at spaced intervals on the upright member.
  • Each securement port of the rosette is elongate having opposed end positions orientated to locate a ledger head with these end positions being 45 degrees apart.
  • Each securement port allows for ledger locating at a host of positions between the end positions.
  • the securement ports are of similar size and adjacent ports are separated by one of 4 support spokes located between said ports.
  • a scaffolding rosette is of a general circular configuration with 4 elongate ledger connection ports of equal size distributed about the rosette and separated from adjacent ledger ports by support spokes.
  • the ports occupy in excess of 70 percent of a circular part of the rosette. In this way, the spokes are less than 30 percent of the circular part of the rosette.
  • a scaffold system comprises a scaffold rosette.
  • the scaffold rosette extends circumferentially around a longitudinal axis and is adapted to support ledgers thereon
  • the scaffold rosette includes a plurality of holes of similar size and shape that extend axially through the scaffold rosette. Each of the plurality of holes extends circumferentially partway about the longitudinal axis between a first circumferential edge and a second circumferential edge thereof.
  • each of the plurality of holes includes a first wedge alignment notch and a second wedge alignment notch spaced apart circumferentially from the first wedge alignment notch.
  • the first wedge alignment notch and the second wedge alignment notch extend radially outward away from the corresponding hole.
  • the first wedge alignment notch of a first hole included in the plurality of holes is spaced apart from the second wedge alignment notch of the first hole by 45 degrees.
  • the first hole includes an arcuate outer edge that extends between and directly interconnects the first wedge alignment notch and the second wedge alignment notch.
  • each of the plurality of holes extends between about 60 degrees and about 65 degrees circumferentially relative to the longitudinal axis between the first circumferential edge and the second circumferential edge thereof.
  • the scaffold system further includes a first rosette orientation mark located radially outward of and circumferentially aligned with the second wedge alignment notch of the first hole and a second rosette orientation mark located radially outward of and circumferentially aligned with a first wedge alignment notch of a second hole located adjacent to the first hole so that the first rosette orientation mark is spaced apart circumferentially from the second rosette orientation mark by 45 degrees.
  • the plurality of holes includes only four holes and the four holes are spaced apart circumferentially equidistant by 90 degrees.
  • the wedge alignment notches are each spaced apart circumferentially equidistant by 45 degrees.
  • the scaffold system further comprises a first ledger located in a first hole included in the plurality of holes and a second ledger located in a second hole included in the plurality of holes.
  • the first ledger is received in a first wedge alignment notch of the first hole and the second ledger is spaced apart circumferentially from a wedge alignment notch of the second hole.
  • a method includes a number of steps.
  • the method includes providing a scaffold rosette that extends circumferentially around a longitudinal axis, the scaffold rosette including a plurality of holes that extend axially through the scaffold rosette, each of the plurality of holes extends circumferentially partway about the longitudinal axis between a first circumferential edge and a second circumferential edge thereof, wherein each of the plurality of holes includes a first wedge alignment notch and a second wedge alignment notch spaced apart circumferentially from the first wedge alignment notch, the first wedge alignment notch and the second wedge alignment notch extend radially outward away from the corresponding hole, locating a first ledger in a first hole included in the plurality of holes, and locating a second ledger in a second hole included in the plurality of holes.
  • the first hole and the second hole are spaced apart circumferentially by 90 degrees and locating the first ledger in the first hole includes locating the first ledger in the second wedge alignment notch of the first hole and locating the second ledger in the second hole includes locating the second ledger spaced apart circumferentially from the first wedge alignment notch and the second wedge alignment notch of the second hole so that the second ledger is spaced apart circumferentially from the first ledger by between 45 degrees and 90 degrees.
