Solution: According to the building code 14, can an ordinary elevator be installed in the closed stairwell? This building is an eight-story hotel.

Please look at the stairs in your drawing 19. It has no steps, the floor height is basically no more than 3.5 meters, and the total height should be below 28. No matter how high the lobby on the first floor is, the total height will not exceed 32 meters. It is a second-class high-rise public building with a height of no more than 32 meters.

Just close the stairwell, and you don't have to smoke the stairwell.

Ordinary elevators can be set up, but it is not necessary to set up fire elevators.

Even fire elevators and evacuation stairs share the front room. As long as the anterior chamber area meets the requirements. Public buildings are not less than 6 meters.

Because only the closed stairwell is not a smoke-proof stairwell, there can be no fire door between the public front room and the stairs.

However, the layout of your stairs is really inconvenient to walk. It's easy to go around such a big circle for the evacuation stairs. Clear signs should be set up.

Article 4.0. 1 1 in Code for Hotel Building Design (JGJ 62-90)

Hotel buildings should be equipped with fire accident lighting and obvious evacuation signs, and their setting standards and scope should comply with the provisions of the fire protection code.
