Hi All...first post and hoping to gain some advice or confirmation that my plan is ok...and not some foolhardy mission!
I have a large (and high) garage with two "toy" cars and workshop. Unfortunately(!) recent purchases of lathe, large pillar drill and all the other accumulated bits 'n' bobs mean I'm running out of floor space.
The plan is to build a storage floor across the width of the garage (4.6m) and for approx. half it's length (3.2m of the 6+m).
This will consist of 47x147mm joists every 400mm, held by joist hangers into the block walls. The ends of each joist will be additionally supported by a bit of 2x2 to the floor (approx. 2.1m), also screwed to the wall as a prop (this will double as some shelving supports etc).
Then I'll run a small RSJ (100x100mm) along the middle of the 4.6m span, underneath the joists. The RSJ will be suspended from the main RSJs by four 12-16mm rods through 10mm thick plates . The original RSJs are roughly 150x75 (iirc?) and sit on top of the block walls.
Then the whole lot will be covered with flooring grade moisture resistant chipboard (the green stuff).
I'm fairly confident the floor will take some good weight (mainly car parts, bicycles...perhaps the odd engine!) and it needs to be VERY strong as this will be over the cars!
Criticism and ideas welcome...thanks
Steve
