Escape system of building

Abstract

The invention discloses an escape system of a building. The escape system comprises a control pulling rope or a control switch arranged on the top floor or the middle floor of the building, a coiled or folded slowly descending rope, and a slowly descending device or a fixing object. The coiled or folded slowly descending rope above the control pulling rope or the control switch can be controlled to vertically drop along the outer side of an outer wall by pulling the control rope or pushing the control switch; one end of the coiled or folded slowly descending rope extends from the slowly descending device or is fixedly connected with the fixing object.

Description

technical field [0001] The application belongs to an escape system for a building. Background technique [0002] The world's second tallest tower, the 540-meter-high Ostankino TV Tower in Russia, suffered a fire, which caused all major Russian TV stations to stop broadcasting. Communications between all paging stations in Moscow, the Ministry of Internal Affairs, and the Moscow emergency system were interrupted. Four people were trapped in the elevator. Death, many people were injured, the structure of the TV tower was seriously damaged, shocking the world, the fire of high-rise buildings has always attracted people's attention, but the reliability of fire elevators in the event of a fire is more worthy of consideration. There is also an arm-raising fire truck used for existing fire rescue and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, which is approximately equivalent to a height of 15 floors.

AI Technical Summary

Problems solved by technology

There is also an arm-raising fire truck used for existing fire rescue and lifesaving, which can generally implement fire fighting and rescue at a height of 53 meters, which is approximately equivalent to a height of 15 floors. Most of the time, fire officers and soldiers can only look at the "fire" and sigh, let alone go upstairs to save people

There is a limit to the height of the fire-fighting aerial ladder truck. Usually, the fire-fighting aerial ladder truck can only rise to about 80% of the limit value. If the ground wind reaches level 4 to 5, the fire-fighting aerial ladder truck will not be able to rise to work

In this way, once a high-rise building above 50 meters catches fire or people are trapped, it is difficult for the fire ladder to play a role. Generally, the trapped people can only rely on their own ability to escape, and the fire-fighting facilities of some high-rise buildings are not complete, and the fire hydrant door is used by residents. Various phenomena such as sundries blockage will bring resistance to fire fighting and escaping

In short, in the traditional high-rise escape, elevators are prohibited and dangerous, and there is a danger of being blocked by fire and thick smoke when taking the stairs, and various descent devices and life-saving equipment for self-rescue escape are unsafe and stable. There are still psychological barriers, not to mention various factors including the safety of the descender, the storage of the descender, the maintenance of the descender, and the hook of the descender affecting the interior aesthetics. There are not many families or users of escape devices

If the user has prepared the descending device, but there are still problems when a fire occurs, the user needs to install and fix the descending device in a short time, which is inconvenient to use and prone to mistakes, especially when a fire occurs. The descending device is often installed and fixed next to the window or balcony. At this time, the fire trucks downstairs will focus on the window or balcony to spray water to extinguish the fire. Most of the descending devices or escape devices are friction-type and are most afraid of water infiltration. , which will reduce the friction and cause the failure of the descending device or escape device. In addition, when a fire occurs, the flame often spreads to the outside of the window or balcony. The high temperature of the flame will also cause the descending device or escape device to fail.
