I would use pressure treated 4 x 4's not more than 48 inches on center around the perimeter all connected with PT 2 x 6's. In addition, within the perimeter add 4 x 4's to support joists running in the 90" direction. Cover all with 2 sheets of 1/2 inch plywood each sheet oriented at right angle to the other.





Use carriage bolts with the 4 x 4's and 2 x 6's. Use dry wall screws to secure the plywood.
