Definitions

  • the present invention relates to arrangements for worker access to scaffolding and the like. More particularly but not exclusively, it relates to stairway arrangements mountable to a range of different forms of scaffolding.
  • Stairways are now being specified on most large building scaffolding contracts. However, on most sites there will be multiple contractors, each using scaffolds of their own preference. It is therefore difficult for site management to identify suitable equipment to fit each of the various designs and dimensions of scaffolding likely to be in use on such sites.
  • an access structure mountable to scaffolding means comprising first and second platform means mountable to the scaffolding means and stairway means mountable to extend between said platform means, wherein the stairway means is provided adjacent a first end with first connector means and adjacent a second end remote from the first with second connector means, said first and second connector means being fasteningly engageable with cooperable connecting means of the first and second platform means respectively.
  • each said cooperable connecting means comprises socket means adapted to receive respective first or second connector means of the stairway means.
  • At least one, optionally each, of the first and second connector means is lockingly engageable with cooperable connecting means of a respective platform means.
  • Said locking engagement may be selectably unlockable, optionally manually.
  • Said locking engagement may occur automatically as the respective connector means engage with cooperable connecting means of the platform means.
  • the first platform means is mountable to the scaffolding means to extend substantially horizontally at a first height
  • the second platform means is mountable to the scaffolding means to extend substantially horizontally at a second height above the first
  • the stairway means is so mountable as to extend diagonally upwardly from the first platform means to the second.
  • the stairway means may be pivotably connectable to the first platform means.
  • the stairway means may be so pivotably connectable to the first platform means that it may be brought pivotingly into engagement with the second platform means.
  • Each platform means may be provided with tread surface means adapted to obviate slipping thereon.
  • Each platform means may be lockably mountable to the scaffolding means, optionally being selectably unlockably mounted thereto.
  • Each platform means may be mountable to substantially horizontal members of the scaffolding means.
  • the access structure is adapted to be partially assembled at a ground level and lifted into position on the scaffolding means, optionally by lifting with crane means.
  • Each of the platform means and the stairway means may extend generally horizontally when partially assembled at a ground level.
  • the connector means may then each engage fasteningly with a corresponding connecting means while the structure is so lifted.
  • the platform means and the stairway means may each comprise a rigid low-density material.
  • Said low density material may comprise a metal, optionally aluminium or titanium.
  • Said low density material may comprise a plastics material, optionally a fibre-reinforced thermoset plastics material.
  • Each of the platform means and the stairway means may have a mass of less than 25kg, optionally less than 20kg.
  • the platform means are each provided with detachably mountable guardrail means.
  • the stairway means is provided with detachably mountable guardrail means.
  • the access structure may optionally comprise three or more platform means and two or more stairway means, each extending between two said platform means.
  • a scaffolding structure comprising an access structure as described in the first aspect above.
  • the scaffolding structure may comprise a main working structure and a linked staircase structure to which the access structure is mounted.
  • a kit of components assemblable into an access structure as described in the first aspect above is provided.
  • This invention relates to a simplified scaffolding stairway system comprising only two principal structural units.
  • this system provides a safe working environment, and may be mounted to most scaffolds without specific adaptation or needing to comply with specific dimensions of the scaffold.
  • both metric and imperial dimensioned scaffold modules are in use.
  • a choice of bay length and lift height for the scaffold may also vary according to the type of work being performed.
  • the present invention comprises stairway and landing units manufactured from lightweight materials incorporating unique attachment and locking details, which enable the stairways to be erected and dismantled without the use of tools.
  • the units are of such dimension and mass to permit their erection by the minimum number of operatives.
  • the system is so designed that using a minimum number of different components, it can be mounted to most conventional scaffolding systems, including tube and fitting scaffolds.
  • a stairway stringer assembly 2 of the present invention comprises a pair of parallel stile members 4 provided with upper attachment hook devices 6 and lower attachment hook devices 8.
  • the stile members 4 are spaced apart by stair-treads 10 supported by and attached to cleat members 12, which are in turn attached to the pair of stile members 4.
  • the upper attachment hook devices 6 are provided with an extended locating portion 14, the function of which is described below.
  • a slotted and barbed upper locking device 16 is pivotably and slideably connected to each upper attachment hook device 6, such that the locking devices 16 are free to rotate and slide along an upper attachment pivot 18.
  • the lower attachment hook devices 8 are each provided with a spigot member 20 pivotally connected to the lower attachment hook device 8 by means of a pivot pin 22 and are each provided with an elongate arcuate slot 24 such that the spigot member 20 may swivel about the pivot pin 22 while being restrained within a predetermined range of angular rotation by a sliding pin 26 held within the slot 24.
  • a lower in use, end of the spigot member 20 comprises a hooked portion 28 to retain the lower end of the spigot member 20 within sockets on a lower landing assembly 30 (see Figures 6a and 6b ).
  • a landing assembly 30 comprises two anti-slip platform deck members 32, 34 provided with pairs of supporting hook members 36, 38, and also provided with a pair of intermediate hook members 40.
  • the intermediate hook members 40 are each provided with locking members 42 pivotably connected to the hook member 40 at a pivot point 44, such that when rotated in a downwardly direction, the locking member 42 inhibits upwardly movement of the intermediate hook members 40.
  • the locking member 42 may be raised manually.
  • the landing assembly 30 incorporates locating pockets 46, 48 to receive the upper 6 and lower 8 attachment hook devices of the stairway assemblies 2 shown in Figure 1 , and for location of stairway banisters and landing guard rails, as described below.
  • a banister assembly 60 comprises two upright post members 62, 64 connected together by upper handrail 66 and intermediate knee-rail members 68.
  • a lower end of each post member 62, 64 incorporates a connecting spigot member 70 provided with a through aperture 72 to receive a safety locking pin.
  • a landing guard rail assembly 80 comprises two upright post members 82 connected together by upper handrail 84 and intermediate knee-rail members, 86.
  • a lower end of each post member 82 incorporates a connecting spigot member 88 provided with a through aperture 90 to receive a safety-locking pin.
  • a conventional access scaffold 100 comprises rows of scaffolding standards A & B, connected together using transom members C and ledger members D.
  • An additional pair of scaffolding standards F are connected to the scaffold 100 using ledgers G, connected each to the other using further ledgers H to form a stairway bay 120, standing alongside the scaffold 100.
  • a landing trimmer post J, together with a short ledger E is installed at a lowest level in the scaffold 100 and a first, lower landing assembly 30 is located in the gap between the scaffolding standard B and the trimmer post J, with its locating pockets 46, 48 facing towards the middle of the bay 120.
  • a second, upper landing assembly 30 is installed at the opposite end of the stair-way bay 120 at a position corresponding to a desired upper end of the stairway, also with its locating pockets 46, 48 facing in an inwardly direction.
  • a stairway stringer 2 is located such that the spigot members 20, 28 of its lower attachment hook devices 8 locate within corresponding locating pockets 46, 48 in the lower landing assembly 30, as shown in more detail in Fig. 6a .
  • the stairway stringer assembly 2 is allowed to rotate away from the erector (see Fig 6b ) until its upper end approaches the upper landing assembly 30 (see Fig. 7a ) This causes a locking device 16 to rotate around its pivot 18, on contact with a rim of a pocket 46, 48 on the upper landing assembly 30.
  • Further landing assemblies, stairways, banisters, landing guardrails and landing trimmers may be installed in sequence until a required height is reached and a fully guarded stairway is produced for access to the scaffold 100.
  • temporary landing handrails may be placed into the banister pockets 46, 48 where there would otherwise be a risk of falling. After the stairways have been installed, these temporary handrails may be replaced with banisters by operators working from a safe position within the scaffold stairway prior to proceeding upwardly. Since all the components are capable of being installed and locked in position without the need for tools, erection of the stairway assembly is rapid, reliable and safe.
