Three-layer composite flexible escape passageway

Abstract

The invention discloses a three-layer composite flexible escape channel. The composite flexible escape channel comprises three layers, the outer layer is a flame-retardant layer, the middle layer is a heat-insulating layer, and the inner layer is a breathable layer. Through the three-layer composite design, the three-layer composite flexible escape channel design of the present invention has the characteristics of integrating many advantages in consideration of its usability and applicability. The outer layer material meets the requirements of fire prevention and aging resistance, and the middle layer plays a very good role. Excellent heat insulation, the design of the inner layer ensures that the escape channel has good air permeability.

Problems solved by technology

[0002] With the rapid development of social economy, there are more and more urban high-rise buildings used for people's daily life, such as office and residence, and high-rise buildings stand everywhere, forming a landscape of urban buildings; but the hidden safety problems are also increasing. increasing, affecting people's daily life

Although high-rise buildings are equipped with fire-fighting equipment, sometimes due to reasons such as untimely discovery of the fire, the fire cannot be effectively controlled in a timely manner. Escape through escape devices such as stair passages, soft ladders, or slow descenders installed in a certain position of a high-rise building. However, before the disaster, the crowd was in a panic, especially for the elderly, weak, sick, disabled, and children. In the process of the method, the escape channel is often not smooth due to crowding and other phenomena, and even a stampede occurs during the escape process, resulting in casualties, which not only affects the normal operation of the above escape methods, but also fails to achieve a good escape effect. Escape time is wasted in vain; similarly, the use of high-altitude flying equipment, whether it is hot air balloons, Ferris wheels, etc. for entertainment, or aircraft used as traffic grounds, is also increasing the catastrophic time. Due to its high-altitude operation, its escape method and escape time are limited in the face of a catastrophic event escape, and the use of a parachute will take a lot of time. Equipment and devices that facilitate escape from heights need to be continuously developed

[0003] At present, although most escape devices can achieve the function of escaping from high-rise buildings, their structural principles are complicated, and there are problems such as relatively fixed installation and use positions, large space occupation, and inconvenient storage; When the device needs power control, when a disaster occurs and the power is cut off, the limitations of its use increase, the practicability of the escape device is not good, and the escape effect achieved is not ideal. In the case of the above disaster, there are still reasons such as untimely escape caused a large number of casualties

[0004] Most of the escape devices used in existing high-rise buildings are used in other emergency situations such as fire, which requires the escape route to have excellent fire resistance to ensure the practicability of the escape route, and also to have excellent heat insulation performance, otherwise When the external heat enters the escape passage, the people involved in the escape passage will be extremely hot and uncomfortable, which greatly increases the discomfort of the persons involved in the escape passage. In addition, the air permeability of the escape passage is also important, and for flexible escape passages, flexible The elasticity of the escape route is also an important performance, otherwise it will affect the safety of the people involved in danger, so there is an urgent need for an escape route that has both fire and flame retardant properties, as well as heat insulation and ventilation, so as to ensure the safety of the people involved in the escape route. safety and comfort
