I do some work in an old barn that is made from stone, the walls are about 2 ft thick and it is about 25ft tall to the eaves so has loads of wasted space high up in the air, the walls have archery slots if thats what they are called at about 4ft centres, the barn is about 22ft wide I have been contemplating running universal beam maybe 200 x200 across through the 'windows' on concrete pads at the base of the windows to consolidate the stone, then board it over with 19mm ish ply as said the centres would be 4ft and the beams would be joined at the 8x4 lboards joints, there would be about 6 beams, I was contemplating storing 3 light ish cars say 3 ton up there plus some other gear like pedestrian snowblower, jet ski spare mower so maybe another ton so 4ton in total,obviously not including the frame and flooring, the cars would be lifted up by 4 post lift and the deck height would be about 3.5 metre. the first beam could have posts or legs situated behind the four post lift. and the last beam could have a centre post. but the rest would be open to park cars under
that would enable 4 extra cars to be parked in the barn but overhead, with one on the lift and the ability for two to be worked on at any time as I have put a two post in there.
My idea is to save having posts at all, bar for the ones mentioned to save on space and maneuverability. and the floor is not good concrete obviously there would have to have a pad for the four post to sit on or I could mount it on a fabricated 16mm steel sheet, as the two poster is.
any views ? any body have any structural calcs for the beams etc. here is me getting the two post plate in and the windows are lined in red on the left
