Abstract:
A chamfer for forming one or more precast panels on a casting surface, said chamfer comprising:a base portion comprising an upper surface and a lower surface such that a base plane is defined along said lower surface, said base portion elongate along a lengthwise direction and including a pair of lateral edges that project along a widthwise direction; and a pair of chamfer portions, each coupled to one of said pair of lateral edges of said base portion such that together said base portion and said chamfer portions define a unitary construction, each of said pair of chamfer portions substantially coextensive with said base portion along said lengthwise direction, each of said pair of chamfer portions comprising: a chamfer surface angularly coupled to said base portion; a first projecting edge disposed at a lower end of said chamfer portion and projecting beyond said base plane, said first projecting edge defining a discrete contact surface for engaging said casting surface such that absent the application of a load to said base portion, a gap is defined between said base plane and a casting surface contact plane upon which said first projecting edge is configured to rest, and further such that, upon application of a load to said base portion of said chamfer, said base portion flexes to splay said first projecting edge, thereby effecting a sealed relationship between said first projecting edge and said casting surface; and a second projecting edge disposed at an upper end of said chamfer portion, said second projecting edge defining a discrete contact surface for engaging a plank to be disposed between said pair of chamfer portions, said second projecting edge configured such that absent the application of a load to said base portion of said chamfer, said second projecting edge can slidably accept said plank, and further such that upon application of a load to said base poriton, said base portion flexes to force said second projecting edges against said plank to form a sealed relationship therebetween.
