随着社会的发展、生活质量的提高,越来越多的歌剧院、博览馆拔地而起,而钢结构在大跨结构中亦运用广泛。本工程南侧博览中心及北侧大剧院通过通过极具张力的大型钢结构飘带连成一体,为支撑上下飘带,本工程大剧院区域设计有2跟直径4.1m的大直径劲性柱。内部劲性组合柱最重达85t,采用220t汽车吊进行吊装;圆柱模板采用定型化木模板及配套柱箍加固体系。
With the development of society and the improvement of the quality of life, more and more opera houses and museums have been built up. Steel structures are also widely used in large-span structures. The Expo Center on the south of the project and the Grand Theater on the north side are connected to each other by streamers of large-scale steel structures with great tension. In order to support the streamers up and down, the large theater area of this project is designed with 2 large-diameter and large-diameter columns of diameter 4.1m. The internal strength of the combined column up to 85t, with 220t car crane for lifting; cylindrical template using fixed wooden formwork and supporting column hoop reinforcement system.
