摘　　要：中国工艺美术馆共有8个型钢混凝土核心筒,核心筒剪力墙内有劲性钢柱和劲性钢梁,筒内设剪刀式楼梯,展厅层层高9 m。施工前通过调整混凝土型号,改进施工工序和优化模架选型等技术措施,取得了混凝土表面平整密实、无麻面的效果,保证了核心筒施工进度,确保了施工工期。There are 8 steel reinforced concrete core tubes in China Arts and Crafts Museum.There are rigid steel columns and beams in the shear wall of the core tube. Scissors stairs are set in the tube, and the floor height of the exhibition hall is 9 m. Before construction, by adjusting the concrete model, improving the construction process and optimizing the formwork selection and other technical measures, the effect of flat and dense concrete surface without pitting surface is achieved,which ensures the construction progress of the core barrel and the construction period.
