Coated Concrete Form

摘要

A concrete form system includes an outer form composed of a structural foam material and a protective skin material. The protective skin material is in contact with the structural foam material and may be chemically bonded such as by crosslinking with the structural foam material. Each of the structural foam material and protective skin material may include a polymeric material. The protective skin material forms an exposed outer surface of the outer form, obviating any need for additional protection from the elements or to be applied during the construction process. The outer form thermally insulates around the periphery of a poured concrete slab, and can be coupled with an inner form, each of the outer form and inner form being assembled in a predetermined relationship and sized so as to control the vertical elevation and thickness of a concrete slab and a foundation stem wall cast between the inner and outer forms. The concrete form system can be pre-assembled in accordance with appropriate dimensions in a workshop in preparation for pouring a concrete slab on a remote job site.

主权项

1. A concrete form system comprising:
an inner form including a first substantially rectangular body having a top peripheral edge and a bottom peripheral edge; an outer form including a second substantially rectangular body having a top peripheral edge and a bottom peripheral edge; a plurality of connecting webs coupling together the inner form and the outer form in spaced apart relation, and such that the first and second substantially rectangular bodies are oriented parallel to one another, for positioning the concrete form system upon a footer; the outer form including a structural foam material forming an inner surface of the second substantially rectangular body, and the inner surface facing the inner form and being structured to contact concrete poured into a space between the inner form and the outer form; and the outer form further including a protective skin material in contact with the structural foam material and forming an exposed outer surface of the outer form located opposite the inner surface.
