默认 fire rated floor deck

fire rated floor deck
does anyone have a detail for a load bearing metal floor deck fire rated 2hr from both sides.

check out our whitepaper library.
any steel beams or just concrete over metal deck?
steel beams fire sprayed, no concrete just metal deck///
bare metal deck without concrete fill has no fire rating. there is no tested ul assembly for bare metal floor deck with spray-on fireproofing.
the closest thing might be metal roof deck w/ spray-on plus roofing but you cannot use this assembly if you have no roofing.
i see no way that you can achieve the 2 hour rating as you are asking. i think that you might be stuck adding concrete plus spray-on.
