Key Construction Technology of Four-tower High-level Connected Steel Truss Structures
Taking the high-rise project of Jiangmen City Archives Center as an example,the project is a four-tower high-level connected structure.The long-span steel truss with suspension is used as the connecting body at the top of the high-rise tower structure to connect the four towers.The structural form is more complicated and the construction is difficult.Therefore,according to the structural characteristics,time limit,site,vertical transportation and other factors,the new integrated construction technology of tire frame assembly,overall lifting after low slip is proposed for the high-level connected truss,and the conventional construction method of high-altitude bulk and temporary support is adopted for the partial suspension truss.On this basis,the overall process and specific implementation points for steel structure construction have been draw up.
