using conrods in footing for pole support?

Hi, has anyone used conrods - embedded in concrete - as footings to support a structure? - It's something I want to try - -I've drawn a very rough sketch (attached) I'm concerned about the strength of the rod - what kind of weight might it be able to handle...etc. The sketch shows a rectangular reinforcing metal attached through the big-end to anchor more in the concrete.
Any comments, advice, warnings ...welcome

I've used con rods or parts of them for many things but never as a j bolt in a footing or foundation. No reason it shouldn't work, just seems like a lot of work if your going to have to line up a series of them.

Hi, thanks for responding - I thought to use a big bucket mold and make individual footings spaced and orientated as necessary?
