what's the proper name given to those metal poles that builders use to
hold up ceilings and overhead beams while they work? They're
adjustable in length and have a centre threaded sleeve for fine adjustment
(can't find a single one on google). Thanks for any
help.

Acro prop?

"Acrow" is a trade name, but is the name by which these things are
usually known, like "Hoover"... (Just "prop" would be the generic name
I think)
