Definitions

  • Scaffolding has long been used in industry for gaining access to high and awkward locations. Whilst scaffolding provides a safe environment for operatives to work this is not always the case for the persons erecting and dismantling scaffolding structures. Various systems exist for providing temporary safety rails guard rails in advance of the erection of the scaffolding tower but they are often difficult to install and adjust.
  • This invention relates to a releasable attachment system whereby the guardrail system may be easily adjusted within the scaffolding tower.
  • the guard rail system is independent from the scaffolding structure and is arranged such that the scaffolding can be erected and dismantled whilst within the perimeter of the guard rail system.
  • the guard rail system may be progressively relocated to higher levels in the scaffold tower providing a safe place of work for the scaffolder to erect further equipment and to erect the permanent guardrail system.
  • the safety rail system may be progressively relocated to lower levels within the scaffold tower to provide a safe working environment for the operatives.
  • the Invention comprises of scaffolding frames 1-4 which incorporate vertical frame members 5 and 6 and multiple, equally pitched, horizontal frame members 7 forming a ladder like structure. These frames together with tie members 8 and bracing members 9 and 10 are coupled together using releasable hook members to form a scaffolding structure.
  • Platform units 11 may be positioned on any rung position to provide a level working platform. The platform must be provided with a safely guarded area for the scaffolding erector to work. This is achieved by attaching a guard rail system comprising of end frames 20 & 21 and telescopic guard rails 22 & 23 which are pivotally and releasably attached to the end frames. This 'guard rail assembly' may be attached to the scaffolding rungs by remotely releasable hook devices.
  • the guard rail end frames 20 & 21 comprise upright members 30 & 31 together with upper and intermediate horizontal members 32 & 33 together with a spacing member 34 which connect the upright members together.
  • Releasable couplings 35 are incorporated near to the upper and intermediate rail positions for the releasable attachment of the telescopic guard rails.
  • Each end frame upright member incorporates a lower hook assembly 36 incorporating twin downward facing receiving apertures 37 & 38 which are dimensioned such that they are a close fit around the scaffolding frame rung members.
  • third and fourth receiving members 39 incorporating horizontally facing receiving apertures 40 are attached to the end frame members at such a position as to present the apertures at a position relating to the position of a frame horizontal member.
  • Hook member 51 are attached to each of the third and fourth receiving members and incorporates an abutment portion 52 and a limiting portion 53 and is pivotally attached to the second receiving member such that the end of the hook member 55 partially blocks the receiving aperture.
  • the end frame upright members each incorporate a sliding member 61 which is located around the upright frame member and incorporates blocking pieces 62 and pairs of operating hand grips 63 and 64 similarly located around the vertical member which are connected to the sliding member by a linking member 65 such that when either the upper or lower hand grips are raised or lowered the sliding member incorporating the blocking piece is raised in unison.
  • Raising of the blocking piece releases the rotating hook such that the hook is free to rotate allowing the restriction in the horizontal receiving aperture to be removed, lowering the blocking device causes the blocking piece to push onto the surface 62 causing the hook to rotate into the blocking position thus preventing the release of the frame from the scaffolding.
  • the scaffolder positions himself in a position within the permanent guarding on the tower and with two hands grips either the upper or lower hand grips whichever is most convenient. Raising both mechanisms simultaneously causes both hook blocking piece to be raised (arrow 'A'), by then drawing the end frame towards himself rotationally (arrow 'C') the hook members are caused to rotate (arrow 'B') opening the jaws of the horizontal receiving aperture.
  • the end frame and attached handrails may be lifted from the tower and may be repositioned at a higher or lower position within the scaffold.
  • guardrail end frames at an inclination to the scaffolding tower frames such that further frame members may be installed or removed. This is achieved by locating the alternative lower hook jaws 38 around the scaffolding rung member such that when the end frame is relocated and locked onto the scaffolding frame an angle is formed between the scaffolding frame 4a and the guardrail end frame member.
