The so-called stair flight is the stair step that we often use to walk up and down. According to the requirements of national regulations, the number of stair steps should not be less than three and the maximum number should not be more than eighteen. There is a connecting part between the two stair flights, which is called the landing. The stairway platform is used for pedestrians to rest. The importance of the stairway platform is that it can become a buffer zone for escaping people in case of a major fire.

Hebei staircase manufacturer Explain the requirements for stair width in housing construction

There are certain requirements in the building architecture: the clear width from the stair flight to the small one is determined according to the use requirements, modulus standards, fire codes and other comprehensive factors. One point to note is that the minimum clear width of residential building sections with six floors and below is 1m. The reason is:

In the past, 2.70 or 2.60 m (not conforming to the 3-mode) bay staircases were generally used to meet the requirements of the fire protection code for stairways with a small width of 1.10 m. At present, the number of service suites is small, and the corresponding stairwell area can also be reduced. For example, if 2.40 m bay staircases are used, the usable area of each set can be increased by about 1 m2, while the 2.40 m bay staircases of brick residential buildings can be used, The width of stairs can only be about 1m.

The 2.40m bay conforms to the 3-module model, and can be coordinated with other parameters of the 3-module model to form a series. There is no half module in the plane layout. It can form an expanded module series with parameters such as 3.60m, which is conducive to reducing components and industrial production. The plane layout is also applicable and flexible.

According to the local survey, 2.40m can meet the use requirements.
