STAY-IN-PLACE FORMWORK WITH ANTI-DEFORMATION PANELS

摘要

A formwork apparatus for forming a concrete structure comprises a plurality of elongated panels comprising connector components at their transverse edges for connecting to one another in edge-adjacent relationship. Each one of the elongated panels comprises an outer surface that extends between its transverse edges and an inner surface that extends between its transverse edges at a location inwardly spaced apart from the outer surface. The inner surface comprises one or more inwardly projecting convexities that extend between the transverse edges. The inwardly projecting convexities may comprise arcuate-shaped surfaces. The inwardly projecting convexities may comprise a plurality of transversely adjacent convexities. There may be brace elements that extend part way between or all the way between the outer and inner surfaces.
