Hi Mary, and welcome!
Sorry to hear your bean supports have collapsed.
If you put the sticks back in and tie securely, then you should be able to grow them on.
I would try to wind the beans back around the sticks gently and tie back on.
Where the main stems have broken, just take the broke bits off, and the remaining plant will probably still produce beans, but not at great height.
It's worth doing though .. Good luck!
