ABSTRACT:
In the poured concrete wall industry, adjacent form panels are commonly coupled together by a slotted pin and wedge combination. Advantageously, the slotted pin and wedge combination includes a sloped wedge so that the narrow end of the wedge is spaced from the wall panels for easy access and disassembly of the pin and wedge when separating the adjacent wall panels after the poured concrete wall has cured. The sloped wedge is formed by a curved inner surface and a curved outer surface extending towards the narrow end of the wedge. With the curved inner and outer surfaces meeting at a rounded blunt end to allow a hammer to strike the wedge free of the slotted pin upon disassembly of the form panels.
