{Fire Evacuation Device For High-Rise Buildings}

FIELD OF THE INVENTION The present invention relates to a fire escape apparatus for a high-rise building, and more particularly, to a fire escape apparatus for a high-rise building for safety, speedy, reliable lifesaving and evacuation in case of fire in a high-rise building.

As is well known, due to the development of technology, the construction of high-rise buildings over 11 floors has been increasing both domestically and abroad.

Currently, there is a method of using elevated ladder car and fire helicopter to evacuate high-rise building fire in 11 floors or more in Korea. However, since the construction trend of skyscraper building has more than 15 floors in recent years, there is no countermeasure and it is difficult to rescue a large number of people at once .

Currently, fire extinguishers for buildings are used mainly as stiffeners, escape ladders, and emergency escape elevators.

However, it is difficult to evacuate a large number of people in a short period of time, and it is difficult for vulnerable groups such as elderly people, children and disabled people to use them, It has a disadvantage that it can not be used in the 15th layer or more.

In case of evacuation ladder, evacuation is normally valid because evacuation to the lower layer is possible, but vulnerable class has a disadvantage that evacuation is difficult.

In addition, in case of emergency escape elevator, it is advantageous that many people can evacuate and evacuation of vulnerable class is easy, but there is a limitation in the number of people to be accommodated, a high installation cost and additional space must be secured, It is disadvantageous that it can not be used when power supply and demand is difficult.

Accordingly, fire escape devices for high-rise buildings are continuously being researched and developed to compensate for the disadvantages of the above-described rigidifiers, escape ladders, and emergency escape elevators.

Korean Patent No. 10-0841211 entitled "Fire Extinguisher for Building" is installed along the horizontal direction of the outer wall of the building, and it is easy to move horizontally and vertically by moving the ferry space through the guide rail It is advantageous to quickly evacuate a large number of personnel in the event of a fire in a high-rise building. However, there is a disadvantage in that it takes a certain time to return to the evacuation position once it has descended after boarding.

"Fire escape evacuation facility" of Korea Registered Patent No. 10-1055294 is a storage evacuation type fire evacuation facility that can accommodate up to 8 passengers at the same time by a storage expansion method when a fire occurs and is easy to install by households and is used as a top storage It can be used as a fire escape in the lower part of an emergency, but it is not a facility to actually evacuate.

In addition, the "emergency evacuation facility" of Korean Patent No. 10-0937832 is a non-protruding installation structure that is used as a normal ventilating window after being fixed to the wall of a building and used as an emergency evacuation port in case of fire, It does not hurt the aesthetics, but it is not a facility to actually evacuate, and it has disadvantages in that it has limitations in office facilities.

As described above, the above-mentioned fire escape devices for buildings also have disadvantages that it is possible to easily and quickly evacuate the various levels of personnel when a fire occurs in a high-rise building.

Therefore, it is urgent to develop a fire escape system for high-rise buildings for safety, speedy and reliable lifesaving and evacuation in case of fire in a high-rise building.
