I need to fit 2 RSJ spanning a gap of 4.44 m. RSJ length calculated at 4.64 m. This allows 100mm to bear onto the brickwork.
The problem I have is that the two supporting walls are double skin without cavities. This leaves now additional gap to allow the RSJ to fit.
Next door will not be happy if I knock through to gain access. Also the Mrs will be ****ed if I knocked through to the adjoining room.
Would it be best to build a small 100mm medium density block work pillar, on one side. This would to allow 100mm to seat on the pillar and 100mm inside the other wall. New RSJ Length 4.54m
