Method of retrofitting a concrete form

A method of retrofitting a support member to a preexisting concrete form having a frame with a first pair of outer frame members and a second pair of outer frame members, said first pair of outer frame members being disposed substantially perpendicular to said second pair of outer frame members so that said first and second pairs of outer frame members define a substantially rectangular shape;

• a first inner frame member connected between two of said outer frame members;
• a second inner frame member connected between said two of said outer frame members and being spaced from said first inner frame member to define a substantially rectangular bay area;
• and a flat concrete-forming member fixed to said frame, said concrete-forming member having a shape substantially identical to said rectangular shape defined by said outer frame members, said method comprising the steps of:
• (a) placing a nonlinear support member having a first end, a second end and a middle portion in a position in which said first end of said support member is adjacent said first inner frame member, in which said second end of said support member is adjacent said second inner frame member, in which said support member is disposed a first distance from one of said outer frame members parallel to said support member and a second distance from another of said outer frame members parallel to said support member, said first distance being less than said second distance, and in which one of said ends of said support member is disposed at a third distance from said concrete-forming member and said middle portion of said nonlinear support member is disposed at a fourth distance from said concrete-forming member, said fourth distance being greater than said third distance;
• and
• (b) securing said support member to said inner frame members so that said support member is maintained in said position defined in said step (a).
