Safety fireproof system device for core tube construction of super high-rise building

Abstract

The invention relates to a safety fireproof system device for super high-rise building core tube construction, and belongs to the technical field of super high-rise building construction.The safety fireproof system device for super high-rise building core tube construction comprises a crawling ladder, the crawling ladder comprises ladder columns and steps, and rotating shafts are rotationally arranged on the ladder columns between the adjacent steps; two shielding nets used for separating adjacent workers are arranged on the rotating shaft in a spaced mode, driving pieces are arranged on the ladder columns and used for driving the rotating shaft to drive the shielding nets to rotate in the direction close to the adjacent steps, clamping columns are slidably arranged in the ladder columns on the two sides between the adjacent steps, and limiting grooves used for being matched with the clamping columns in a clamped mode are formed in the two ends of the rotating shaft; sliding plates used for being held by workers are arranged at the two ends of the steps below the rotating shafts in a sliding mode, and transmission assemblies used for driving the clamping columns above the sliding plates to slide in the direction close to or away from the corresponding limiting grooves are arranged on the sliding plates. The escape ladder has the effects that the safety of the escape ladder is improved, and safe evacuation of workers is guaranteed.

Description

technical field [0001] The application relates to the technical field of super high-rise building construction, and in particular, to a safety fire protection system device for the construction of a core tube of a super-high-rise building. Background technique [0002] The core tube refers to the central core tube in the central part of the building, which is formed by the elevator shaft, stairs, ventilation shafts, cable shafts, public toilets, and some equipment rooms. It forms an outer frame and inner tube structure with the peripheral frame. The mainstream structural form widely used in super high-rise buildings. When a fire occurs in the operation layer of the core tube, it will seriously threaten the life and health of the personnel at the operation layer, so it is very important to set up a safety fire protection system device in the operation layer of the core tube. [0003] In the related art, for example, the Chinese patent document with publication number CN10187...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor found that when a fire broke out, the workers were more panicked and climbed down from the escape ladder at a speed that was fast or slow. Unnecessary casualties such as falls are prone to occur
