Abstract: The disclosure presents a composite concrete structure formwork which comprises stay in place fiberglass profiles and reinforcement to form various building and shelter structures. The structures include an interior container maintained at a set distance within an exterior container to form a void. The void is filled with wet concrete which is allowed to cure. All of the components in a preferred embodiment are formed of a fiberglass material.

Abstract: The disclosure presents a composite column formwork which utilizes a fiber reinforced polymer (FRP) stay in place container which incorporates horizontally coplanar support chairs bonded to the interior surface, closed ties bonded to the support chairs and a plurality of longitudinal rebar enforcements bonded to the closed ties. All of the components in a preferred embodiment are formed of a fiberglass material.

Abstract: The disclosure presents a composite conduit formwork structure which includes a cylindrical outer casing adapted to bond with a cylindrical inner casing which are maintained at a fixed distance apart by a plurality of radial stanchions. The inner casing and outer casing form an interior void which is filled with concrete during manufacture. The outer casing and inner casing remain in place to protect the structure once completed. A novel method of assembly is also provided whereby radial stanchions are rotated between the outer casing and inner casing. All of the components in a preferred embodiment are formed of a fiberglass material.

Abstract: The disclosure presents a reconfigurable composite floor formwork which defined by a plurality of interlocking fiberglass panels formed into profiles which may be moved and adapted to provide a concrete form for a floor or ceiling. All of the components in a preferred embodiment are formed of a fiberglass material.

Abstract: The disclosure presents a formwork system which utilizes Fiber Reinforced Polymer (FRP) panels to create modular segments to form and reinforce concrete subgrade structures. The segments may be rearranged and bonded together to conform to intended dimensions of many subgrade structures. The segments are manufactured by cast molding, bonding or vacuum forming. The segments may include integrated FRP stanchions to prevent deflection of the panels during concrete placement. The stanchions also may be used for positioning structural steel or FRP rebar. FRP bars are permanently bonded to the interior sides of the panels inside the segments. In use, the assembled segments are filled with concrete. After the concrete is cured, the segments remain in place and function as external protection and reinforcement for the cured concrete.
