As the title suggests, I would like to build a dance floor over my in-ground pool for our wedding at the end of this month. Since I want this to be as safe as possible, I figured I'd better ask for some suggestions. Here is the situation:
The pool is 12' wide by 40' long. Ideally I would like the dance floor to cover 30' of the pool length, leaving the last 10' open for a fountain.
My initial idea was to use 2x10's on 16" centers that are 16' long. This means that each one would hang over the edge of the pool by 2 feet. I would also use 2x10's along the outside, with joist hangers for each beam going across the pool.
Or should I buy I-beams to span the pool and do 20 or so of them on 16" centers?
I would like to avoid supporting beams in the pool, since I don't think they would do much good. The pool has a sand bottom with a liner over it (If you take your heel and stomp really hard multiple times you can dent the bottom of the pool).
For safety's sake we'll assume that the dance floor could be full of people. We're expecting around 200 people at our wedding, so we'll assume very high and say 100 people on this dance floor at the same time.
Any help or ideas would be greatly appreciated. Thanks!👍
