Abstract:
1. Scaffolding for supporting a worker elevated above the ground, said scaffolding comprising: a walkboard presenting a support surface on which the worker may be supported, said walkboard including a horizontally extending plank including a pair of opposite ends and presenting said support surfaces, said walkboard further including at least one flange that is coupled to the plank and extends lengthwise between the ends, said flange including at least a portion thereof extending vertically from the plank; and a scaffold frame configured to support the walkboard above the ground, said frame including a pair of spaced apart upright support posts, said frame further including a ledger coupled to the support posts and extending therebetween to define a longitudinal ledger axis, said ledger including an outer wall that presents an arcuate upper surface extending along the ledger axis, said wall including a plurality of slot-defining edges that cooperatively present a generally orthogonal shaped slot in which the flange is received, said support surface extending beyond both sides of the ledger when the flange is received in the slot, said edges including a pair of recessed edges spaced below the upper surface and extending along the ledger axis, said flange resting on and being supported by the recessed edges, said plank being spaced from the recessed edges when the flange is received in the slot, said edges further including a pair of abutment edges spaced along the ledger axis, with the abutment edges projecting substantially perpendicularly between the recessed edges and extending to the upper surface to generally prevent the walkboard from shifting along the ledger axis when the flange engages one of the abutment edges.
