Abstract:
1. A stay-in-place form for casting structures from concrete or other curable construction materials comprising: a plurality of elongate panels interconnectable in edge-to-edge relationship via complementary connector components on their longitudinal edges to define at least a portion of a perimeter of the form; wherein each panel comprises a first connector component comprising a protrusion on a first longitudinal edge thereof and a second connector component comprising a receptacle on a second longitudinal edge thereof; wherein interconnection of the panels to one another in edge-to-edge relationship forms edge-to-edge connections therebetween; wherein for each edge-to-edge connection between a first one of the panels and a second one of the panels, the first connector component of the first one of the panels and the second connector component of the second one of the panels comprise shapes contoured such that relative pivotal motion between the first connector component of the first one of the panels and the second connector component of the second one of the panels about an axis generally parallel to at least one of the longitudinal edges creates the edge-to-edge connection by causing:
