I want to put a stronger floor in the loft. At the moment the joists in the loft are only 75x50 with the joints running from front to back of the property. Now I have had a structural engineer around and he said he would have to calculate the new floor as a proper floor because of the spans involved. 3.8m being the largest span
What is being proposed is a steel beam put on to a load bearing wall and into the party wall. Then have the new joists run parallel next to the existing joists.
My question is, how should the joists be fixed at the ends where they rest on wall?
I understand that I will need a timber packer underneath the joists. I'm just not sure on the fixing side as I don't was the joists to start twisting
The house was built in 1959 and built with a hip roof. There is a piece of timber propping up each purlin on supporting walls with what I think you call hangers fixed to the rafters and then to the ceiling joists, these rest on the purlins
