I need to construct some extensive, but not load bearing, stud walls in our workshop. Trouble is, the mezzanine against which I want to secure the top plate is a steel girder construction, approx 3 metres off the ground.
I'm guessing it will affect the integrity of the steel if I drill it and simply bolt the top plate to the bottom chord with, say, an M8 bolt. Is there an established fixing that could be secured to the top of the top plate and simply stop it shifting back and forth, with just tight fitting studs holding the top plate in place.
The mezzanine is well supported,and the loads it bears will be minimal-all the lathes and heavy plant are downstairs on concrete.
