What's the distance between the fire stairs in the 22nd floor hotel?

"Code for Fire Protection Design of High-rise Civil Buildings" has no special requirements on the stair spacing, only stipulates that the spacing between two safety exits should not be less than 5 meters (meaning that the safety exits should be set separately and not together). I think what you want to know is the safe evacuation distance. According to the situation you described, you should meet the following requirements: when the room is located at two safety exits, the maximum distance between the room door and the nearest stairwell should not be more than 40 meters, and when the room is located at both sides or at the end of the bag-like walkway, it should not be more than 20 meters.
