Tearing up a floor, 22mm chipboard on floor joists, glued and screwed, I thought it would be relatively easy to detach the board from the joists but it's stuck firm. Is there any good trick to use here? I have 80m2 to tear up and it will take 3 eternities at this pace. All I can think of is maybe using the circular saw along the joists. I also intended to reuse the joists, but that seems out of the question.
Remove the screw and use an electric planer. It'll be quick.
It might work well on the edge shown in the picture, but then I have 20-25 more joists completely under the particleboard, can you reach those with an electric planer? (I've never used one, so I don't know).
I did the equivalent on about 40 square meters. We used a plunge saw, which quickly removed the majority of the boards. Then we made a cut 5cm on each side of the floor joists and then a cut 5cm on each side of the screws, allowing us to easily knock away the pieces between the screws (which are only glued to the floor joists). You then have to unscrew/pry up the screws. Surprisingly little residue was left, which we cleaned up with a chisel and electric planer.

Thanks, that's how it will be, tested a bit more today, with a larger crowbar, it can be pried that way, but only small pieces come loose. Damn, wood glue is strong!
A 40m2 room done, went well without sawing for the most part, wasn't glued as well everywhere, about 80% could be broken up with a crowbar and a large pry bar. Borrowed an electric planer that worked well to remove the remaining chipboard on the joists, which I will reuse.
