Description

technical field [0001] The invention relates to a building escape passage.

The straight-line distance of the nearest evacuation exit should not exceed 20 meters. However, when a fire occurs, people in a high-rise building need to drop down the stairs through the evacuation stairs. However, the evacuation stairs are inside the building, which are easily f...

AI Technical Summary

Problems solved by technology

However, when a fire occurs, people in high-rise buildings need to drop down the stairs through the evacuation stairs, but the evacuation stairs are inside the building, which is easily filled with smoke and heated, and has poor safety performance

In addition, it takes a lot of time for residents to escape through the evacuation stairs, and it is easy to be grilled, and the safety performance is not high.
