Description

Fire disaster self-descending escape device for high-rise building

Technical Field

The application relates to the technical field of escape equipment, in particular to a high-rise building fire disaster conjoint self-descending escape device.

Background

With the rapid development of social economy and the continuous increase of urban population, the places for people to live, live and work are increasingly narrow. The high-rise building has the advantages of small occupied area, high volume ratio, attractive appearance, intensification and the like, and is the first choice for urban development and construction. Therefore, the number is more and more, the floors are built higher, diversified and comprehensive functions are presented, and the method becomes an important carrier for modern urban construction combination and urban image display. However, in high-rise buildings, a large amount of people and materials are concentrated, and various lines and pipelines are criss-cross, so that fire is easily induced. When a fire disaster happens, the elevator cannot run, people are confused, crowded and escape, and treading injury is easy to happen due to the extremely low speed of the escalator; other approaches such as sliding down a window with a rope, climbing a building's outer wall duct, riding an elevator, and gliding a glider are not optimal. The fire spreading speed in the high-rise building is high, the chimney effect is easy to form, toxic smoke can quickly spread to stairs or evacuation channels, the escape speed and life safety of people are seriously influenced, and a serious disaster of group death and group injury is easily caused.

Fire control is the most important project for guaranteeing life safety, and although various escape equipment and facilities exist at present, the technical means which are really suitable for people in middle-high-rise, high-rise and super high-rise buildings to quickly escape and are convenient for rescue are very lacking. Various escape devices provided in the existing high-rise building are difficult to meet the requirement of safe and rapid evacuation of all people when a fire disaster happens, and have more defects. The following are examples:

1. the high-rise building with the building height of over 100m is a floor specially set for fire safety for people to evacuate and refuge according to the 'building design fire protection code' GB50016-2014 in China. A refuge layer is built on every 15 floors of a high-rise civil building with the height of more than 100 meters, and the refuge layer is mainly divided into the following three types according to the mode:

(1) an open refuge layer: the building protection device is arranged on the top layer or the flat roof of the building, has no surrounding components around, simple structure, poorer protection capability, can not ensure that the building protection device is not invaded by smoke, can not block wind, sand, rain and snow, is only suitable for warm areas, and is difficult for people in the building to save themselves, obtain rescue and break away from a fire scene.

(2) Semi-open refuge layer: the protection wall with the height not less than 1.2m is arranged on the periphery, the window and the fixed metal louver are arranged on the upper portion, smoke can be prevented from entering, good ventilation conditions are achieved, natural smoke exhaust can be achieved, and the smoke exhaust device is not suitable for cold areas, and people cannot evacuate from a fire scene.

(3) A closed refuge layer: the periphery and the partition wall adopt fire-resistant protection walls, an independent air conditioning system and an independent smoke prevention and exhaust system are arranged in the room, and the outer wall and the partition wall are not provided with doors and windows generally; if the door and window are opened, a first-level fireproof door and window is adopted; the closed refuge layer can prevent the invasion of smoke and flame and the influence of outside weather. However, the fire power failure can lead to the paralysis of the air conditioning and smoke preventing and discharging system and the incapability of people to evacuate the fire-stricken building.

2. The existing escape devices are mainly divided into slow-descent ropes, gliding pipelines, elevators, gliding aircrafts and the like, and are not suitable for being used by children, pregnant women, old people and disabled people. The personnel in the building are difficult to realize the purposes of self rescue, rescue and rapid fire scene evacuation.

3. The elevator generally adopted by the Japanese residences is provided with an entrance which is directly communicated with the ground on the floor of each floor, and escapers can drill into the entrance and descend downwards.

4. The escape slideway newly invented by England designers is a long cylindrical device which is made of flexible fireproof materials and vertically faces downwards, escapers enter the flexible cylindrical slideway from special inlets arranged in all floors to fall, the speed of the escapers is reduced due to the weight of the escapers, the escapers are easy to extrude in pipelines, and the escape slideway is not suitable for pregnant women, babies, the elderly, the infirm and the disabled and does not have universal application functions.

For review: in case of fire, safe and rapid evacuation of personnel is the only option. People of different ages and different constitutions inevitably exist in the high-rise building; the difference between the fire environment and the building design, and the facility conditions of high-rise residences do not necessarily meet the requirements. It is not easy to equip various slow-descent ropes, gliding pipelines, elevators, gliding aircraft, parachutes and other equipment; even with equipment, the equipment is not always sufficient, is more difficult to operate, and is not suitable for all evacuees. The measures have a plurality of defects, and all the personnel can not be ensured to be evacuated quickly and safely.
