Stair installation system

Abstract

The invention discloses a stair installation system. The stair installation system comprises an installation assembly, an installed assembly and an adaptive function assembly; the installation assembly comprises a tower crane hanging piece, first steel wire ropes, a balance steel beam, a second steel wire rope, a chain block, a connecting piece and a steel wire rope hanging piece; and the connecting piece is connected below the tower crane hanging piece, the steel wire rope hanging piece is connected below the connecting piece, the two first steel wire ropes are hung below the steel wire rope hanging piece, the balance steel beam is hung below the two first steel wire ropes, the chain block is hung below one end of the balance steel beam, and the second steel wire rope is hung below the other end of the balance steel beam.

Description

technical field [0001] The invention relates to the construction field, in particular to a stair installation system. Background technique [0002] In the field of construction, technology has developed rapidly in recent years, and some new technologies such as BIM (Building Information Modeling) technology and new fire prevention technology have been gradually applied. Among them, BIM technology is generally used to build visual modeling management and intelligent control, and new fire prevention technologies include ventilation technology. [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 t...

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.
