My wife and I bought a put-it-together-yourself gazebo from a hardware/outdoor type store (think Home Depot or Big Lots type of place). It is rectangular gazebo (10'(w) x 12'(l) x 10'(h)) with a cloth roof and sides. The box of parts says it all weighs about 130 lbs (60 kg).
I'm trying to figure out how to anchor this down. The instruction manual is one of those look-at-the-picture-and-guess-how-it-goes-together deals. The only thing it shows is "put stake in ground". Each corner has a small base plate with holes for 4 stakes. Each stake is an 6-ish inch long L-shaped stake with "threads" on them (they look like threads on a screw except they are wide, something like 1/8 of an inch or so).
Being an engineer (but not the kind that deals with structures or anything) I'm trying to figure out if staking into the dirt is sufficient or if I need something like concrete to anchor this down. I'm also trying to not over-engineer this. My biggest concern it that if I don't anchor this down sufficiently, I'll have a gazebo trying to make a forceful entry into my kitchen one day.
So my question has a couple (related) parts:
- Is anchoring into the dirt sufficient?
- If not, would concrete be a good way to anchor it? If so, how much per foot do I need to use?
My initial thought was to put one to two 50 lb bags of concrete mix in a hole at each corner. I've never done concrete by myself before (aside from digging holes for it with my dad when I was younger) so this is all somewhat new territory for me.
