The development of urban development seems to be "high" with the heavenly Gong, and constantly refreshed the height of the urban skyline. According to one statistical data, the existing high -rise buildings in the country (above 8 floors, more than 24 meters) 347,000 buildings, over 100 meters of super high -rise high -rise, over 100 meters or more More than 6,000, the number ranks first in the world.

However, the building's upward "grow", which also puts forward higher requirements for the ability of residents to emerge and self -rescue. As early as ten years ago, Kong Lijun, who started the production storage and handling equipment and accessories, keenly saw the hidden demand of the emergency self -rescue equipment market. The products include vehicle emergency boxes, fire life boxes, seismic equipment, and so on.

Among the many emergency equipment, Kong Lijun's most optimistic and most effort was a high -rise escape device. "We spent two years before the research and development!"

The high -rise escape device in the mouth of Kong Li's mouth can be simply understood as a rope device, part of which is fixed on the wall, and the other is the main body slowing device composed of hooking, seat belt, rope and speed controller, etc. On the upper body, the person hangs from the window to escape downstairs.

On a high -rise building of "Sega Life Equipment", the tester demonstrated this "escape device" to us on the spot. He descended to the ground from about ten meters from three floors, and only 10 numbers jumped on the stopwatch! According to Kong Lijun, they have also done tests. The same floor, the speed of falling downstairs with their high -rise escape device is 5 times that of the stairs. Once high -rise buildings such as fire occurred, this is a life channel.

However, it is not easy to reach 100 % safe and reliable by ropes. "Whether it is material or structural design, we first consider the safety factor!" Kong Lijun said that all the components of this escape device are used for fire materials. At the end of 2012, at the end of 2012, the state promulgated national standards (GB21976.2-2012) for building fire escape equipment, high-altitude slowders. ! Including the safety hook required by the national standard, there should be insurance devices that prevent it by mistake. After the rope intensity test, there must be no significant deformation and broken phenomenon. We are all the standard standards. "

"In terms of structural design, we also consider the control of the decline speed. For example, the slowdown device is pulled by the human body weight. We have installed 4 bronze in the internal device, relying on its opening and closing调节。”孔立军解释道，人体高空下降的速度每秒低于三米，都是安全的，而他们这款高楼逃生器的数据测算显示，重约100斤的人，在这个缓降器上， It drops about 0.8 meters per second, far lower than the safety value, and does not produce any feeling of weightlessness, which can fall steadily.

"Of course, each device has a safety limit. Based on 3 meters high per floor, about 120 meters of about 40 floors is the limit of this device." Kong Lijun said.
