Technical Field

The invention relates to the technical field of buildings, in particular to a novel anti-skid limiting device for an inverted air pipe.

Background

In the architectural design, in order to satisfy the requirements of fire control and smoke exhaust and ventilation, a vertical tube well needs to be arranged, and a vertical air pipe is installed in the tube well. Conventional forward installation is from one floor up to the roof. The method is often in danger of opening holes, narrow installation space, easy risk of falling from high position of constructors and the like, and the air pipes need to be transported to each layer, thus having extremely low efficiency. The project innovation uses the mode of big discrepancy in elevation tuber pipe flip-chip to carry out the construction. And (4) transporting the single air duct to the bottom and the middle part of the vertical shaft according to the position of the vertical shaft, and intensively assembling the air ducts. First tuber pipe is fixed the back by fixing device, promotes in the shaft through the hoisting device on upper portion, promotes the high back of an tuber pipe, connects the second tuber pipe, promotes an tuber pipe height again, connects gradually the installation, makes assembling of tuber pipe all the time in the fixed position on low floor, effectively promotes construction speed and quality.

The air duct flip-chip technology is also used, and the following defects exist: 1. along with the tuber pipe constantly upwards promote the installation, the weight of tuber pipe is increasing equally, if certain connecting piece is connected insecure, easily takes place the tuber pipe risk of falling. 2. The tuber pipe uses the hoist engine to promote the in-process, can produce and rock, leads to tuber pipe flange card in entrance to a cave department, and the hoist engine does not in time stop promoting, easily causes the hoist engine to burn out or the steel wire scheduling problem of breaking.
