There should be no less than two elevators in each building, and the reasons are as follows:

In a narrow sense, high-rise refers to residential buildings with 12 floors or more, and elevators according to the "Residential Design Code".

For residential buildings with 12 floors or more, there should be no less than two elevators in each building, and one elevator that can accommodate stretchers should be installed.

Legal analysis: The residential building design code for buildings with more than seven floors stipulates that elevators shall be installed for residences with seven floors or more, or residences with the highest entrance floor and a height of more than 16m from the indoor ground floor on the ground floor.

Legal basis: Article 6 of the "Residential Design Code" When one of the following situations is applied, an elevator must be set up:

When the height of the entrance floor of a residential or residential building with seven or more floors exceeds 16 m from the outdoor design floor;

When the floor of a residential building with six floors or less on the ground floor is used as a shop or other building, and the floor of the entrance floor of the tenant is more than 16 m from the designed outdoor ground level of the building;

When the floor of a residential building with six floors or less on the ground floor is used as an overhead floor or storage space, and the floor height of the entrance floor of the household is more than 16 m from the outdoor design ground of the building;

When the top floor is a two-storey duplex dwelling, the height of the entrance floor of the top floor is more than 16 m from the outdoor design ground of the building, regardless of the number of floors.

The state stipulates that elevators need to be installed on the seventh floor and above of buildings.

According to Article 6 of the "Residential Design Code", an elevator must be set up in one of the following situations:

1. The height of the entrance floor of a residential or residential building with seven floors or more than seven floors is more than 16m from the outdoor design ground.

2. For residential buildings with six floors or less on the ground floor as shops or other buildings, the floor of the entrance floor of the residential forest barricade is more than 16m away from the outdoor design ground of the building.

3. For residential buildings with six floors or less than six floors on the ground floor as an overhead layer or storage space, the height of the entrance floor of the residential floor is more than 16m from the outdoor design ground of the building.

4. When the top floor is a set of two floors, the number of floors is not counted, and the height of the entrance floor of the top floor of the building from the outdoor design ground of the building exceeds 12 floors and above the 12 floors of Weifan high-rise residences, and each building shall be equipped with no less than two elevators. Tower and corridor residential elevators should be arranged in groups. When there is only one elevator per unit of a unit-type dwelling, it should be connected by a corridor on the appropriate floor.

The number of floors that need to be set up has a lot to do with the purpose of the building, and the scope of the too wide is not determined.

However, according to China's "Mandatory Provisions of Engineering Construction Standards Lu Heng" on the mandatory standards for the installation of elevators in housing buildings, that is, residential buildings with seven floors or more or the entrance of the house must be equipped with elevators with a height of more than 16 meters from the outdoor design ground; Elevators should be set up in office buildings with six floors or more, buildings for the elderly with more than four floors, the height of the floor of the highest residential floor of the dormitory from the ground of the entrance floor is greater than 20 meters, and hospital outpatient buildings or ward buildings with four floors or more should be equipped with elevators.

The number of floors that need to be set up has a lot to do with the purpose of the building, and there is no definite range of liquid barriers.

However, according to the mandatory standards for the installation of elevators in housing buildings in China's "Mandatory Provisions on Engineering Construction Standards", that is, residences with seven floors or more or residences with a height of more than 16 meters from the outdoor design ground at the entrance floor of the house must be equipped with elevators; Elevators should be set up in office buildings with six floors or more, buildings with more than four floors for the elderly, the height of the floor of the highest residential floor of the dormitory from the ground of the entrance floor is greater than 20 meters, and hospital outpatient buildings or ward buildings with four or more floors of four floors.

In daily life, most of the buildings have to start thinking about the problem of elevator trouble after reaching the 7th floor.

Seven floors and above.

There is a relevant provision in the Residential Design Return Hole Code: Residences with seven floors or more or the height of the entrance floor of the resident building with a height of more than 16 meters from the outdoor design ground must be equipped with an elevator.

For multi-storey dwellings with overhead floors or storage space on the ground floor, elevators must be installed when the entrance floor of the residents exceeds 16m from the outdoor ground height of the building;

If the top floor is a two-storey house, the number of floors is not counted. When the height of the entrance floor of the residential floor of the front floor is not more than 16m from the outdoor design ground of the building, there is no elevator.

Answer] Article 1 of the :d Design Standards for Office Buildings" (JGJ T 67-2019) stipulates that elevators shall be provided for office buildings with four floors or more or if the height of the building is more than 12m from the outdoor design ground.
