【Abstract】 Taking the Nanjing Zhengrong G64-A plot construction project as the background, the hoisting and positioning of double semi-staircase components used in the construction process are described in detail. The technology solves the problems of heavy precast component, larger tower crane selection and high construction cost encountered in the traditional construction of single precast staircase and moreover, it has the advantages of simple working procedure,shorter construction period, good construction results and high quality, which can provide reference for other similar projects.更多还原
