  • Double bias corner form
    Patent number: 6502802
    Abstract: A corner form assembly for forming inside corners of concrete structures. A pair of double bias form components, each of which has an acute angle between a side rail and the face sheet are arranged with the side rails in contact engagement to form a form assembly with an inside angle equal to twice the acute angle of the side rails. A reverse bias coupler is used to join the double bias form components with conventional wall form panels having 90° end rails. The corner assembly acts to release the forces imposed on the components by the poured concrete upon disassembly and so allows the components to be readily stripped from the poured wall.
