A reinforced concrete building structure (10) and method of forming, including first forming a steel framing form (18) of cold formed channel shaped structural steel members of a thickness between 1/32 inch and ⅜inch including vertical framing members (19,20,21,22) and horizontal connecting members

A reinforced concrete building structure (10) and method of forming, including first forming a steel framing form (18) of cold formed channel shaped structural steel members of a thickness between 1/32 inch and ⅜inch including vertical framing members (19,20,21,22) and horizontal connecting members (30A-30E), then connecting a backing form (74) by connectors (76) to flanges (26) on only one side of the vertical framing members (19-22), and only adjacent the lower side of the horizontal connecting members (30A-30E) spaced at least ¾inch from the steel framing members. Concrete is then applied pneumatically against the backing form (74) for the vertical side walls (12) with the channel shaped framing members (19-22) comprising the primary steel reinforcing and with opposed flanges (26,27) being covered outwardly by concrete at least ¾inch in thickness. The steel framing for a roof of a relatively large span is shown in FIGS. 7-9 and separate spaced reinforced concrete layers are provided adjacent opposite sides of wide flange steel beams (50).

A method of building a continuous non-modular reinforced concrete wall in situ comprising the steps of: constructing a steel framing form of a plurality of spaced parallel steel framing members with said steel framing members being of a channel shape including a web with flanges extending therefrom,

A method of building a continuous non-modular reinforced concrete wall in situ comprising the steps of: constructing a steel framing form of a plurality of spaced parallel steel framing members with said steel framing members being of a channel shape including a web with flanges extending therefrom, said steel framing members being of a thickness between 1/32 inch and ⅜inch; mounting transversely extending reinforcing members on said steel framing members; positioning a backing form adjacent flanges of said steel framing members on one side of said steel framing form; mounting a plurality of spaced connectors between said backing form and said adjacent flanges for removably securing said backing from onto said steel members and spacing said backing form at least ¾inch from said adjacent flanges; pneumatically applying concrete against said backing form only from the other side of said steel framing form of a thickness sufficient to cover said transversely extending reinforcing members and said adjacent flanges; and removing said backing form and said connectors from said steel members after setting of said concrete thereby to provide a panel construction about said adjacent flanges on one side of said steel framing form for forming the continuous reinforced concrete wall.
