Ingi,
I sure can send you pictures. Please provide me with your e-mail address. If you do not wish to make your e-mail address public, please send it to me via private message or to
marc@integraspec.com Meanwhile take a look at the following link.
www.integraspec.com/noncombustible/noncombut.html . It will give you an idea on how it could be achieved. Although, the link is an example of achieving a wall with a concrete face on one side and foam on the other side but basically it would be a very similar situation for installing the rebar in a very tight fashion prior to closing your wall.
Regards,
Marc Philippe
