Description

Inter-building special-shaped overlapped steel structure corridor installation construction method Technical Field The invention relates to the technical field of steel structure corridor installation construction, in particular to an inter-building special-shaped overlapped steel structure corridor installation construction method. Background With the continuous development of high-rise building construction, the steel structure is widely applied due to the advantages of high strength, light dead weight, short construction period and the like. In high-rise buildings, steel structure corridors are often used to connect different towers to achieve the integrity of building functions. However, in the traditional steel structure installation and corridor construction process, the problems of high overhead workload and high safety risk exist, component hoisting depends on large equipment, is limited by the site and equipment performance, has low construction efficiency, is difficult to control the installation precision of embedded parts and the butting precision of components, influences the structural stability, and has high erection difficulty of assembled jig frames and outstanding quality and safety risk when the corridor parts are in high-altitude bulk. Because steel construction vestibule installation belongs to high altitude construction, if adopt the high altitude bulk packing of branch, not only high altitude equipment, welding work load are big, and on-the-spot mechanical equipment also hardly satisfies the hoist and mount requirement, and the assembly jig frame of required high altitude is difficult to set up moreover, has very big safety, quality risk. The construction difficulty is high, and the safety, quality and construction period control of the steel structure on-site installation are not facilitated. Therefore, the steel structure corridor is assembled in advance in the prior art, and then the assembled steel structure corridor is lifted to the designated height by the lifting equipment. This mode of operation is less difficult to implement for single-layer or simple-structure steel construction galleries. But to high-rise building, often there is the steel construction vestibule of high floor and the steel construction vestibule of low floor to have the phenomenon of overlapping in vertical direction, and this kind of overlapping vestibule structure is because the vestibule of low floor can influence the promotion of high-rise vestibule, and consequently the construction degree of difficulty is big, and the efficiency of construction is low.
