<p>This invention pertains to a novel component for constructing concrete forms. More particularly, this invention pertains to a T-bolt channel beam comprising: (a) an elongated hollow channel member; (b) an elongated T-bolt receiving first cavity formed in a top region of the channel member, said elongated cavity having therein a first elongated opening which is parallel with the elongated channel member and exposes the interior of the first elongated cavity to the exterior, said first cavity having a pair of opposing lips facing one another and constructed along respective sides of the elongated first opening exposing the interior of the first cavity; (c) an elongated second cavity formed in the interior of the elongated channel member, adjacent to and parallel with the elongated first cavity and communicating by a second opening with the first cavity; (d) an elongated third cavity, formed in the interior of the elongated channel member, adjacent to and parallel with the second cavity and first cavity, and separated in part from the second cavity by an elongated membrane and communicating by a third opening with the second cavity; and (e) an elongated T-bolt receiving fourth cavity, inverted and symmetrical in orientation with the first cavity, and adjacent to and parallel with the third cavity, communicating by a fourth opening with the third cavity and fourth cavity having therein an elongated fifth opening which is parallel with the elongated channel member and exposes the interior of the fourth elongated cavity to the exterior, said fourth cavity having a pair of opposing lips facing one another and constructed along respective sides of the elongated fifth opening exposing the interior of the fourth cavity.</p> |
