Abstract

In this paper, we explore the installation method and process of large-span air corridor curtain wall of Chongqing Raffles Square Project. The curtain wall is positioned at the lower part of the sightseeing overpass, with the spans of 48.5m, 52.6m and 54.1m respectively, and the lengths of the cantilever sections are 25.1m and 26.8m. At the junction of two rivers in Chongqing, several super high-rise buildings nearby exert strong aerodynamic interference effects. It is difficult to construct this project in a conventional way because intense airflow exists. Through an analysis of two construction options, with consideration to difficulties, quality, safety and economic costs of construction by the two options, the overall lifting of aluminum plate unit is chosen as the final plan. An introduction is made to practical operations of this option, including assembly of aluminum plate unit V-frame, tire frame installation, aluminum plate surface layer assembly, hydraulic synchronous lifting and unit body fixing. The hydraulic synchronous lifting process details the technical key points such as lifting point setting, lifting angle control, lifting and windproof measures, hydraulic lifting force control, hydraulic synchronous lifting control, etc. Finally, by utilizing this option, the quality, construction schedule, safety and cost for the overall lifting of units aloft can be guaranteed and good results are achieved in practice.
