Research on Cantilever Assembly Construction of Large-span Steel Beam in High-rise Building
The No.2 Hotel Project of CDF Mall Phase Ⅰ has a large span variable cross-section steel beam.Due to the limitation of construction conditions,cantilever assembly method is adopted for construction after comprehensive consideration.By analyzing the construction difficulties of cantilever assembly of large-span steel beams,this paper formulates the assembly construction scheme,analyzes the hoisting load of steel beams,and puts forward the corresponding quality control measures,which are used to guide the hoisting of steel beams and the on-site construction of corresponding measures,so as to ensure the construction of steel structure engineering with safe,reasonable,efficient,civilized and high-quality construction organization.
