Abstract
Abstract In order to make it possible to align a concrete form while at the same time providing a safe working walkway therealong, a scaffold bracket comprises a generally triangular shaped brace having an attachment leg, a plank supporting leg and a brace leg. The attachment leg is adapted to be secured to an outer surface of the concrete form, the plank supporting leg extends generally transversely of the attachment leg, and the brace leg extends from the attachment leg to the plank supporting leg at an acute angle to both the attachment leg and the plank supporting leg. A first stop is provided on the plank supporting leg at a preselected distance outwardly of the attachment leg to define a waler bracket for accepting a plank of predetermined width for aligning the concrete form. A second stop is provided on the plank supporting leg at a preselected distance outwardly of the first stop to define an outer limit for accepting one or more planks of predetermined width for creating a working walkway. The brace is configured in such manner that the attachment leg can cooperate with one or more spaced fasteners on the outer surface of the concrete form such that the attachment leg is secured to the spaced fasteners with the planks of predetermined width suitably positioned on the plank supporting leg. In a preferred embodiment of the scaffold bracket of the present invention, the second stop takes the form of a guardrail pocket having an opening adapted to accept an upright for forming a guardrail with other such uprights at the outer limit of the working walkway.
