Extension type escaping window

Abstract

The invention relates to the field of fire safety, in particular to an extended escape window. The basic window frame is fixed on the window wall, and two main slides are arranged on both sides of the basic window frame, and the main slides extend downward to a height greater than twice the window height. Position, both sides of the sliding window frame are slidingly connected with the main slideway, one side of the sliding window frame is the main shaft, and one side of several extended frame window frames and one side of the locked window frame are all connected to the main shaft in rotation, the sliding window frame, several extended frame window frames The side away from the main axis between the locked window frame and the locked window frame is connected by a flexible belt, the upper part of the sliding window frame, several extended frame window frames and the locked window frame is connected by a flexible refractory cloth, and the sliding window frame, several extended frame window frames The lower part between the locked window frame and the locked window frame is connected by a flexible pressure-bearing belt. For high-rise fire survival, it is more stable and safe, and an expansion space can be isolated, and the escapees are waiting for rescue in this space. Compared with the existing way of escaping from the scene, it is more suitable for high-rise escape.

Description

technical field [0001] The invention relates to the field of fire safety, in particular to an extended escape window. Background technique [0002] When a fire breaks out in a high-rise building, how to evacuate the affected people as quickly as possible and reduce the casualties of fire personnel is a major problem in the field of fire safety. After a high-rise building suffers a fire, the fire tends to spread horizontally and vertically, accompanied by a large amount of smoke, and escaping from stairs or fire elevators is prone to confusion, resulting in stampede accidents. [0003] At present, high-level firefighting mainly uses ladders, high-pressure water cannons, and helicopters to extinguish fires. It is difficult for firefighters to go deep into the fire scene for rescue, and human rescue consumes a lot of physical strength of firefighters, resulting in a lower rescue success rate. In view of this situation, some patents have proposed its improvement scheme, such as...

After a high-rise building suffers a fire, the fire tends to spread horizontally and vertically, accompanied by a large amount of smoke, and escaping from stairs or fire elevators is prone to confusion, resulting in stampede accidents

[0003] At present, high-rise firefighting mainly uses ladders, high-pressure water cannons, and helicopters to extinguish fires. It is difficult for firefighters to go deep into the fire scene for rescue, and human rescue consumes a lot of physical strength of firefighters, resulting in a lower rescue success rate.

In view of this situation, some patents have proposed its improvement scheme, such as a part of the escape window, which can put down the escape ladder by itself, which is convenient for self-rescue. There is a certain risk, and an escape tool should be designed to isolate the fire scene and help the people trapped in the fire to carry out safer and more reliable self-rescue
