Safety emergency stair assembly for high-rise building

Abstract

The invention discloses a safety emergency stair assembly for a high-rise building. The safety emergency stair assembly comprises a stair body, a platform, a guiding storage cabinet, a stair dividing wall plate, a flow adjusting assembly, a filter screen frame, a sun shield, a containing groove and a hoisting block; the flow adjusting assembly comprises a shell, a main fan blade, a connecting rod, a telescopic rod, a driven fan blade, a first expansion block, a first push rod, a first short rod, a first rotating rod, a first long rod, a first insertion rod, a second expansion block, a second push rod, a second short rod, a second rotating rod, a second long rod and a second insertion rod; a motor, a first rod, a pivot, a second rod and a filter screen are mounted on the filter screen frame; and a first slot and a second slot are formed in the hoisting block.

Description

technical field [0001] The invention relates to the construction field, in particular to a high-rise building safety emergency staircase assembly. Background technique [0002] Fire prevention and ventilation are important technical issues in high-rise buildings, especially in recent years, new types of high-rise buildings, such as high-rise factory buildings, high-rise wooden structures, high-rise hospital buildings combined with epidemic prevention, etc. Higher integration requirements. [0003] In the event of a fire, the stairwell is an important escape route. However, when the fire is too large, it is easy to produce a large amount of thick smoke, which will cause difficulties and obstacles to escape from the stairwell. At this time, the improvement of details is important for safety. [0004] The deficiencies of prior art are as follows: [0005] 1. There are windows in the stairwell of the prior art, but due to the height of the stairs, the windows are far away from...

AI Technical Summary

Problems solved by technology

[0005] 1. There are windows in the stairwell of the prior art, but due to the height of the stairs, the windows are far away from the bottom of the stairs in order to facilitate artificial opening, so the bottom of the stairs cannot gather the smoke, and the smoke cannot be guided and discharged from the window

[0006] 2. In the stairwell of the existing technology, the windows cannot be opened automatically in case of fire, and it is not reliable to rely on manual opening in panic

[0007] 3. The flue fusing structure of the prior art is more suitable for small-volume components, but there is no solution for the fusing control of large-volume components due to instability and infirmity.

[0008] 4. The transmission paths in the prior art are often connected, but there is no solution in the prior art for the need to disengage and connect the transmission

[0009] 5. Ventilation equipment in the prior art can generally only realize opening and closing adjustment, but cannot realize third-level ventilation adjustment

[0010] 6. With the storage structure of the prior art, if the stored objects are unfolded, they cannot be automatically stored into the storage space

[0011] 7. Due to the fire in the stairwell of the prior art, thick smoke will enter the mouth and nose when escaping, and there is no time and no chance to take a wet towel when escaping

[0012] 8. Due to the limited expansion ratio of the expansion block in the prior art, it is always impossible to obtain a large-stroke expansion drive during expansion.
