Reinforced concrete building construction and method of forming same

A method of building a reinforced concrete vertical wall comprising the steps of:

• constructing a vertically extending steel framing form of parallel vertical extending steel members having a thickness between 1/32 inch and 3/8 inch, said steel members being of a channel shape including a web with flanges extending therefrom and secured for maintaining a precise position;
• positioning a vertically extending backing form adjacent flanges of said vertically extending steel members on one side of said steel framing;
• mounting a plurality of connectors through said backing form and through said adjacent flanges for removably connecting said backing form onto said steel members and spacing said backing form at least 3/4 inch from said adjacent flanges;
• pneumatically applying concrete from the other side of said steel framing form against said backing form about said steel framing of a thickness sufficient to extend outwardly from the opposite side of steel framing at least 3/4 inch and to enclose entirely said steel framing form for forming said concrete vertical wall with said steel framing form constituting reinforcing for said concrete vertical wall;
• and
• removing said backing form and said connectors from said steel members after setting of said concrete thereby to complete said reinforced concrete vertical wall.

A method of building a continuous non-modular reinforced concrete vertical wall comprising the steps of:

• constructing a vertically extending steel framing form of a plurality of spaced parallel vertically extending steel framing members with said steel framing members being of a channel shape including a web with flanges extending therefrom;
• positioning a wire mesh material on each side of said steel framing form and securing said wire mesh material to the adjacent flanges of the parallel steel framing members;
• providing a plurality of spaced adjacent openings in the web of said parallel steel framing members;
• positioning a plurality of horizontally extending reinforcing bars within said aligned openings of said steel framing members for providing reinforcing;
• positioning a vertically extending backing form adjacent the flanges of said parallel steel members on one side only of said steel framing form;
• securing a plurality of connectors to said backing form and the adjacent flanges of said parallel steel members for spacing said backing form at least 3/4 inch from said adjacent flanges;
• pneumatically applying concrete against said backing form about said steel framing form of a thickness to extend outwardly from the opposite side of said steel framing form at least 3/4 inch and to enclose entirely said steel framing form for forming said concrete vertical wall with said steel framing form constituting reinforcing for said concrete;
• and
• removing said backing form and connectors from said steel members after setting of said concrete.

A method of building a continuous non-modular reinforced concrete vertical wall in situ comprising the steps of:

• constructing a vertically extending steel framing form of a plurality of spaced parallel vertically extending steel framing members with said steel framing members including a web with flanges extending therefrom;
• securing horizontally extending reinforcing members between said vertically extending steel framing members;
• positioning a vertically extending backing form adjacent flanges of said steel framing members on one side of said steel framing form in a predetermined spaced relation to said adjacent flanges;
• removably mounting said backing form onto said adjacent flanges at a redetermined distance from said adjacent flanges;
• pneumatically applying concrete from the other side of said steel framing form against said backing form of a thickness sufficient to enclose completely said vertically extending framing members and said horizontally extending reinforcing members to form the reinforced concrete wall of a predetermined thickness with said framing form providing a major portion of the steel reinforcing;
• and
• removing said backing form from said steel members after setting of said concrete to provide the continuous reinforced concrete vertical wall.
