In a self-supporting concrete form of foamed polymeric material, a one piece transverse connecting member is provided which mechanically holds fastening members inserted into the form providing mechanical support for finish material such as furring strips, paneling, etc. The connecting member is formed from one piece of sheet material, preferably cold rolled steel, and comprises a central connecting web portion extending between and embedded in sidewall members of the form and first and second imperforate flat attachment flange portions extending perpendicularly from the web portion and embedded near the outer surfaces of the sidewall members for supportably receiving fastening members penetrating the sidewall members. The web portion of the connecting member comprises an array of relatively large openings to permit the flow of concrete through the form units and to provide a high strength web of metal. The connecting members may be arranged in each form unit with one connecting member midway between the longitudinal center and each end of the form unit so that, when the form units are laid up in courses in a staggered array, the connecting members of form units in succeeding courses are aligned.

In a self-supporting form of polymeric material comprising first and second sidewall members extending in length on either side of a cavity disposed to receive flowable construction material, the combination comprising: a one piece transverse connecting member of sheet material extending between and embedded in said first and second sidewall members and comprising: a central, connecting web portion extending between said first and second sidewall members and serving to define said cavity therebetween, and having therein a plurality of openings for permitting flow therethrough of said flowable construction material; and attachment flange means integral with said central, connecting web portion, extending transversely relative to the central, connecting web portion, embedded in at least one of said sidewall members, and located relatively closely adjacent an outer side surface of one of said sidewall members in a predetermined relationship to said length of the sidewall members for enabling location thereof and fixed mechanical attachment of building materials thereto, said attachment flange means forming a substantially imperforate continuous planar surface for supportably receiving fastening members penetrating a sidewall member.
