Taking a high-rise hotel as an example, this paper expounds in detail the basis for determining the location and quantity of buildings and elevators.

1, safety evacuation exits are scattered, and the distance between entrances and exits is more than 5m.

2. The maximum distance from the room door of a high-rise hotel to the nearest external exit or stairwell:

Space between two safety exits -30m.

Rooms on both sides or at the end of the bag-shaped walkway-15m.

3. The branch distance from any point in the hall to the nearest evacuation exit should not exceed 30m.

4. The straight-line distance from any point in the parking garage to the nearest evacuation exit shall not exceed 60m.

5, each fire zone has at least 2 safety evacuation stairs.

6. Each fire compartment of the underground garage shall have at least two safety exits. When there are two or more fire zones and fire doors are installed on the firewall between adjacent fire zones, each fire zone should be provided with a safety evacuation staircase leading directly to the outside.

3. There are more than 300 underground garages, belonging to 1 underground garage. Vehicle evacuation exit adopts two lanes and three entrances and exits.

The number of fire elevators shall be determined according to the following high-rise buildings:

6.3. 1. 1 Class I public buildings; (Hotel)

6.3. 1.2 tower residence;

6.3. 1.3 12 floors and above apartment buildings and veranda houses;

6.3. 1.4 Other Class II public buildings with a height exceeding 32m.

6.3.2 The number of fire elevators in high-rise buildings shall meet the following requirements:

6.3.2. 1 When the building area of each floor is not greater than1500m 2, one should be set;

When the 6.3.2.2 is greater than1500m 2 but not greater than 4500m^2, two sets shall be set;

6.3.2.3 is more than 4500m^2, so three sets should be set;

6.3.2.4 fire elevator can be used with passenger elevator or working elevator at the same time, but it should meet the requirements of fire elevator.
