Allotments 4 All

Hi ,  i was building my greenhouse and when the frame was up i stopped ( as i don't have the glass yet).

when i got to the allotment this morning the wind blew it over and all the corner nuts and bolts were ripped out.  in other words the corner on the frames doe not have holes anymore as a piece of the aluminium is gone.

this was only on a few corner parts -  anyone got an idea how i can fix that ?

i assume once the glass is in it will be heavy enough to withstand the wind.
