Hello
Torn down the old hayloft in the barn and now I'm planning to build a new one. I want to use it for storage but also for future crayfish parties, etc...
The dimensions are 11.3*7.3 (inner measurements) for the part I intend to start with. Planning a floor structure of 45x195 cc400 or 45x220 cc 60. With a support beam in the middle, I have access to a galvanized I-beam or perhaps called HEA? which measures 18*18cm.
The question is, what dimensions do I need for the support beam? Is 18*18cm enough?
I'm also considering if it might be better to have 2 support beams instead; then I could reduce the floor structure to 45*170. Then the span between the support beams would be 2.43cm. But what is required for support beams then? However, I prefer to have as few posts as possible.
On the floor structure, there will be self-sawn planed and tongue-and-groove 34*120-195 spruce flooring.
Does anyone have an idea and can help me?
Best regards
Johan

How long are the steel beams? Do you have any requirements for deflection, it could be a good swing at a crayfish party?
I built a new floor for my old hayloft a few years ago with a span of 4.80m and 45x195 cc60. On top of that 1.5" boards as flooring. It feels very stable and good. So if you add an extra support beam in the middle and 45x200 cc60, you'll get a good loft. Now, there will surely be people who argue the opposite, referring to today's building codes where floors shouldn't have the slightest deflection. But one must learn to differentiate between old barns and newly built residential houses. Good luck with the crayfish party!!!
Exactly, hence the question regarding any requirements for deflection. Otherwise, you should follow the standard whether it's a loft in a stable or a villa.
The deflection standard is incredibly important for the experience of walking on a floor structure. It should be followed for one's own sake, not to please the authorities.
Hello and thank you for the responses! Yes, it can get a bit wild at a crayfish party, of course. The beams are 5 meters long, a friend can weld them together. What do you think, would it work with those supports?

If you have access to your own saw and timber, I would suggest cutting 50x250 as floor joists. Then a support beam in the middle will suffice, and you can have both a crayfish party and barn dance.
The beams are 5 meters long but can be welded together. What do you think about the beams?The risks of welding galvanized metal are not the healthiest for the body, but maybe your friend is aware of that? So, in total, there will be 2 joints? These should be butt-welded since the joints are likely to end up in unsuitable places. Another option could be to bolt the beams together. You place a 5m beam on two pillars and hang the other beams on either side of this beam.
