Abstract

This invention pertains to a novel component for constructing concrete forms. More particularly, this invention pertains to a concrete form system component comprising interlocking novel channel form beams and T-bolt connections. A T-bolt channel form beam including: (a) an elongated hollow channel member; (b) an elongated T-bolt received first cavity formed in a top region of the channel member, said elongated cavity having therein an elongated opening which is parallel with the elongated channel member and exposes the interior of the first elongated cavity to the exterior; (c) an elongated second cavity formed in the interior of the elongated channel member, adjacent to and parallel with the elongated first cavity; (d) an elongated third cavity, adjacent to and parallel with the second cavity and first cavity, and separated in part from the second cavity by an elongated membrane; and (e) an elongated T-bolt receiving fourth cavity, reversed in orientation with the first cavity, and adjacent to and parallel with the third cavity, the fourth cavity having therein an elongated opening which is parallel with the elongated channel member and exposes the interior of the first elongated cavity to the exterior.
