Tubular escaping chute structure

Abstract

The invention discloses a tubular escaping chute structure, and belongs to the field of fire-fighting. The chute is arranged in a building, is of a spiral bend structure from top to bottom and is of a tubular cavity structure; the two ends of the chute are provided with an entrance and an exit; the chute comprises a multi-layer structure; the multi-layer structure comprises a refractory layer on the outer layer of the chute, a bearing layer on the middle layer and a water layer; the inner wall of the chute is provided with a fire detector; the periphery of the entrance is connected with a water supply device and an air supply device. By using the structure, the escaping speed can be quickened, the escaping time can be shortened, the physical exhaustion can be reduced and the death of people due to the smoke and the fire disaster can be reduced by using the chute under the conditions of fire disasters or other conditions, particularly under the condition that smoke enters the staircase.

Description

technical field [0001] The invention relates to an escape slide, in particular to a tubular escape slide structure, which belongs to the field of fire protection. Background technique [0002] With the acceleration of urbanization in our country, the urban population is increasing year by year, the buildings in the city are getting higher and higher, and the population is getting denser. The fire safety of the city and the escape routes of the buildings are becoming more and more important. , Stairs and elevators are the two main forms of solving vertical traffic problems in buildings. In case of disasters such as fire, the elevator will automatically stop at the first floor and cannot be used for escape. In this case, escape through the stairs is the only way As an escape route, due to the current trend of high-rise buildings, when using stairs to escape in high-rise buildings, the distance to the bottom floor increases. The evacuation of the disaster site mainly relies on ...

AI Technical Summary

Problems solved by technology

[0003] Stairs are used as escape routes for buildings, especially high-rise buildings, where the escape speed is relatively slow. In order to deal with fires, stairs are expensive and the only escape route. Once the stairs enter the smoke, they will bring certain harm to the survivors. Problem, the present invention provides a tubular escape slide structure, the purpose is to increase escape channels, evacuate the disaster site as soon as possible, and reduce the threat of disasters to personal safety
