Reinforced insulated forms for constructing concrete walls and floors
View Patent ↗A panel for a building form made of insulating material such as polystyrene is integrated with a reinforcing member for enabling the panel to resist deformation due to forces applied against its concrete-facing surface. Reinforcement of floor/roof panels is beneficial to reduce the amount of, or eliminate the need for, shoring for supporting the weight of wet concrete or workers. The reinforcement resists against deformation due to cracking, splitting etc. Reinforcement is likewise beneficial for wall forms where the weight of concrete asserts significant pressure against the concrete-facing surface of the form, in order to resist deformation of the wall forms under pressure. The reinforcing member may be made of a plastic material such as polypropylene or high-impact polystyrene. Methods of manufacturing reinforced form panels are disclosed.
1. An insulating form for supporting poured concrete during construction of a concrete wall or floor comprising:
a panel made of a foamed plastic insulating material, said panel having a concrete-facing surface that faces concrete poured thereagainst, and an outward facing surface; and

11. An insulating wall form for supporting poured concrete during construction of a concrete wall comprising:
a panel made of a foamed plastic insulating material, said panel having a concrete-facing surface that faces concrete poured thereagainst, and an outward facing surface, said panel adapted to be in a fixed spaced relationship with another panel by way of at least one bridging tie embedded in and extending between the panels to form a concrete chamber for receiving a charge of poured concrete; and
at least one reinforcing member encapsulated within said panel and distinct from the at least one bridging tie, said reinforcing member arranged with respect to said panel to limit deformation of said panel during application of force of pouring concrete against said concrete-facing surface during construction of the concrete wall against said concrete-facing surface, wherein said at least one reinforcing member is rebar having gripping structure extending therefrom, and is encapsulated within the panel, said at least one bridging tie protruding from said concrete-facing surface of said panel, said at least one bridging tie for maintaining said fixed spaced relationship with said other panel, said at least one bridging tie for connecting to said other panel, said rebar comprising at least one tie clip for connecting said rebar to a respective one of said at least one bridging tie.
12. The form of claim 11 , wherein said gripping structure comprises at least one protrusion extending outwards from the rebar.
13. The form of claim 11 , wherein said rebar is made of one of high impact polystyrene; polypropylene; another plastic; wood; and metal.
14. The form of claim 11 , wherein said panel and said rebar have at least one of a curved portion and an angled portion.
15. The form of claim 14 , wherein said rebar further comprises a reinforcer through said at least one of a curved portion and an angled portion.
16. The form of claim 11 , wherein said rebar is made of plastic.
17. The form of claim 16 , wherein said plastic is high impact polystyrene.
18. The form of claim 17 , wherein said high impact polystyrene is fused with said panel during formation of said panel.
19. An insulating floor/roof form for supporting poured concrete during construction of a concrete floor/roof comprising:
a panel made of a foamed plastic insulating material, said panel having a concrete-facing surface that faces concrete poured thereagainst, and an outward facing surface, said panel also having at least one abutting surface for abutting a respective adjacent panel; and
at least one reinforcing member encapsulated within said panel, said reinforcing member arranged with respect to said panel to limit deformation of said panel during application of force of pouring concrete against said concrete-facing surface during construction of the concrete floor/roof against said concrete-facing surface, wherein said at least one reinforcing member is rebar having gripping structure extending therefrom, and is encapsulated within the panel,
wherein said panel is adapted to be in a fixed spaced relationship with another panel as a wall form, and wherein said concrete-facing surface of said panel has protruding therefrom at least one bridging tie, said at least one bridging tie for maintaining said fixed spaced relationship with said other panel, said at least one bridging tie for connecting to said other panel, and said rebar comprises at least one tie clip for connecting said rebar to a respective one of said at least one bridging tie.
20. The form of claim 19 , wherein said at least one abutting surface is part of a respective abutting side of said panel, said respective abutting side dimensioned to, in combination with said adjacent panel, form a channel for receiving poured concrete.
21. The form of claim 19 , wherein said gripping structure comprises at least one protrusion extending outwards from the rebar.
22. The form of claim 19 , wherein said rebar is made of one of high impact polystyrene; polypropylene; another plastic; wood; and metal.
