Problems solved by technology
Steel structure corridors are currently used in building construction, and most of them use high-altitude bulk installations. The maximum installation elevation of steel corridor structures is +45.05m. It is difficult to meet the hoisting requirements, and the required high-altitude group tire frame is difficult to erect, and the construction is difficult, which is not conducive to the safety, quality and construction period control of the steel structure on-site installation, and there are great safety and quality risks. poor connectivity

The invention discloses a high-altitude large-span steel structure corridor and a lifting construction method thereof, and relates to the technical field of building construction steel structure corridor lifting. The technical scheme is that the high-altitude large-span steel structure corridor comprises a middle lifting unit and hoisting units arranged on the two sides of the lifting unit, wherein the lifting unit comprises an ellipsoidal middle lifting section; each hoisting unit comprises a first hoisting end, a second hoisting end and a bulk section. The high-altitude large-span steel structure corridor has the beneficial effects that the comprehensive lifting construction method is used, so that the whole steel corridor is divided into the combination of three parts; the construction mode of two-side segmented lifting and middle overall lifting is adopted, so that the construction speed, construction safety and construction quality of steel structure corridor installation are improved, and the overall stability of the steel structure corridor is improved; the installation and construction difficulty is greatly reduced, and control over quality, safety, construction period, construction cost and the like is facilitated.
Description
technical field [0001] The invention relates to the technical field of lifting steel structure corridors in building construction, in particular to a high-altitude long-span steel structure corridor and a lifting construction method thereof. Background technique [0002] Steel structures are widely used in high-rise buildings due to their advantages and characteristics such as light weight, short construction period, and strong earthquake resistance. Steel structure corridors are currently used in building construction, and most of them use high-altitude bulk installations. The maximum installation elevation of steel corridor structures is +45.05m. It is difficult to meet the hoisting requirements, and the required high-altitude group tire frame is difficult to erect, and the construction is difficult, which is not conducive to the safety, quality and construction period control of the steel structure on-site installation, and there are great safety and quality risks. Poor ...
