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. Recent changes in legislation require that scaffolding erectors and dismantlers are provided with safety systems such as safety harnesses or platform units, which must include guard-rail protection, at all times whilst erecting, altering and dismantling scaffolding.
- This invention relates to a platform system which incorporates attachment hooks which enable the platform units to be more easily relocated within the scaffolding structure.
- a totally enclosed safety platform and guardrail system is provided.
- the hooks on the platform unit are arranged such that accidental removal or displacement of the platform unit or disturbance by external forces such as wind forces is prevented, but whereby the intentional removal or repositioning of the platform unit remains unimpeded.
- the Invention is for use on scaffolding towers comprising scaffolding frames (2 & 4) which incorporate vertical frame members (6) and multiple, horizontal frame members (8) forming a ladder like structure.
- the scaffolding frames are connected together by horizontal members (10 & 12) and diagonal bracing members (14 & 16) such that the scaffolding forms a rigid rectangular framework.
- Scaffolding platform units (20) are provided which may be releasably attached to the scaffolding horizontal frame members.
- the platform units may be positioned on any rung position to provide a level working platform.
- the platform unit comprises side frame members (22), decking surface members (24 & 26), usually comprising of a flat anti-slip plywood member, and a trapdoor panel (28) hingeably connected to one side frame member.
- the platform incorporates hook devices (30) at each corner of the platform for the support of the platform unit at the desired position.
- the hook devices incorporate a jaw portion (32) with an upper hook portion (34) and a lower hook portion (36) an inclined face (38) a recessed portion (40) and a pivotal connection portion (42) enabling the hook members to be pivotally connected to the platform side members.
- a locking device (44) comprising of a. pivotally connecting portion (46) located into a. recessed portion in opposite frame side members and an engaging portion (48) which locates against the recessed hook portion (40) and hangs downwards with the engaging portion engaging within the recessed portion of the hook members.
- a spring device (50) may be incorporated at the pivotal connection point to cause the locking device to be forcibly engaged with the book member. In use the hook member is prevented from rotating past point 'D' since the recessed portion engages firmly against the engaging portion and which due to the relative positioning of the pivot points prevents the further rotation of me hook mechanism.
- the locking device actively prevents the rotation of the hook members however, when the platform unit is required to be intentionally detached from the scaffolding frame rung members the locking device is rotated from position 'A' through position 'B' to position 'C' such that when one end of the platform unit is raised the hooks are free to rotate and become disengaged from the horizontal frame member. Further raising allows the hooks to hang downwards permitting the platform end to be raised past the frame members above.
- the locking device is released which then applies a force by manual or spring action against the inclined face of the hooks causing the hooks to return to their original position permitting the hooks to be re-engaged onto the required horizontal frame member.
- the hooks may be engaged between frame members at differing levels and consequently different separating distances.
- the locking device at the opposite end of the platform unit may be disengaged and the other end of the platform may be raised to a level position.
- the platform may be adjusted from below using an elongate actuator or operated from above using pull cords connected to the locking mechanism and to the platform unit.
- the platform unit is first placed on the tower at a convenient level. From a convenient position either above or below the platform unit the locking device at on end of the platform is released manually and simultaneously one end of the platform unit may then be raised to (position 1 or position 2) the hooks rotate downwards away from the horizontal member(s) immediately above the hooks whereby further raising movement allows the hooks to pass the horizontal member(s).
- the locking mechanism After passing the horizontal member(s) the locking mechanism is released causing the books return to their original position and the platform hooks may then be located onto the horizontal frame member. This procedure is continued at opposite ends of the platform unit (position 3) until the desired height is reached and the platform unit is horizontal (position 4).
- the locking devices are automatically deployed which prevents the platforms from being raised and the books from being detached from the structure.
