I've got this super to fix:

I'm not sure if it's damaged beyond being fixable. The wood sides are buckled out of place. I have two clamps that I can use to help push the sides back into place, I could then use glue and screws to try and put it back together.
I could tear it apart and separate the four sides, and then maybe see if I can somehow flatten them.
Not too sure how to go about fixing this either way. Let me know if you guys have any thoughts on what the best approach would be. If I manage to fix the super it'll be sitting in an urban backyard under shelter so doesn't need to be perfect.
I would put your clamps on it and replace the nails with long screws.
You will need to check to see if the bottom and top are still flat.

2nd Jim's remarks. If feasible, go ahead & disassemble, clean joints the glue, clamp & screw. Like Jim said ck for level. I do it all the time.
A tip I was taught by an old cabinet maker never screw the screws in straight with the grain of the wood. angle them 5 to 15 degrees try to miss or just let a very little bit of screw show on the inside corner. This makes a stronger joint even with a box joint. Set the screw to start it as far from from the end as is practical; this is old stuff most woodworkers know, but not all BEEKs are woodworkers. I use all deck screws on my hives to prevent rust. Merry Christmas ALL.
