Hello everyone.
I have been reading passively for a while, but this is my first active question.
I would like to install a walkable intermediate floor in our house to store various items. The room above which the intermediate ceiling is to be built measures 350cm x 950cm (11.5 ft x 31.2 ft). I was thinking of using beams (supported on joist hangers?), spanning the shorter distance (350cm / 11.5 ft). On top of these, OSB floorboards or similar would be installed. The walls where the beams are to be attached are masonry on one side and concrete on the other. Additionally, there are two window arches and two door openings in these walls (would this be a problem, since the beams would be fixed above them?).
My question is: how strong do the beams need to be dimensioned, and at what spacing should they be installed? I have some rafters from an old attic available with dimensions of 150 x 100mm (6 x 4 inches). Would these be suitable for this purpose?
Thank you very much for your help. If anything is unclear, please feel free to ask.
