Concrete Roof

larrylwillFebruary 1, 2012

I just finished building a tornado shelter in the bedroom. I poured a 5" concrete slab with re-bar for the roof. The roof is 35" x 47" The form is 2 pieces of 3/4 osb with plastic on top held up all around the edges with block and 2 4x4 posts to prevent sagging. This was done last Sunday 1/29

Does anyone have an idea how long I have to wait until I can remove the 2 supports?

Was this based off of an engineered plan?

What does that matter. Quickcreat and re-bar 5" thick 35x47"
The shelter was based on Fema specs but to my dimensions.
