What are the design requirements for the width of the passenger elevator hall and the waiting hall of the direct elevator?

Because many design units do more residential buildings, residential buildings are often elevator halls or front rooms shared by fire fighting, and they are used to making fire doors, so I often find this problem and remind everyone in particular.

The above rules can generally be applied to buildings below 150M to 200M. However, for super-high-rise buildings above 150M, or even over 300M and 300M, the area of each floor is large and the total area is large, which leads to the large area of the core tube arranged in the elevator. However, the core tube with a ratio of 150M or more is in terms of content, structure and total area. Therefore, it is necessary to analyze the function of this super high-rise building. For example, the upper part is probably the hotel, the floor for sightseeing and dining, and the apartment is above it. Therefore, it is necessary to make full use of the upper part of the elevator shaft in the lower half of the core barrel. How to use it? We can arrange a high-speed direct elevator in the lobby on the first floor, and one stop will reach the aerial conversion floor above 150M. Then it is divided into 2-3 sections like the following half method, so that the core tube is reduced to more than 150M, which can save a lot of net use area.

This kind of passenger elevator, which carries half the people in the building and arrives at the delivery hall in the air, should pay attention to the concentration of people on the first floor lobby during rush hours. In the elevator lobby with a width of 4 m, people are often nervous. Since it is not a fire escape, people can directly use the lobby to expand their waiting space.
