【摘要】：型钢混凝土组合结构是近年来研究的多元化结构形式之一,成功的应用被越来越多的建筑界专家所瞩目。天津周大福金融中心工程建筑高度530m,其中塔楼外框角柱结构最大截面尺寸3 000mm×17 650mm,组合结构钢管柱内外分布高强度超大直径密集钢筋,单根封闭箍筋最长25m,施工难度大。本工程利用BIM技术提前进行深化设计,优化钢筋安装方式、自制双槽钢模板背楞、创新高强度混凝土冬季浇筑顺序,节约了施工成本,达到了预期效果。
[Abstract]:Steel reinforced concrete composite structure is one of the multiple structural forms studied in recent years. The successful application has attracted the attention of more and more experts in the field of architecture. The building height of Tianjin Chow Tai Fook Financial Center is 530m, in which the maximum cross section size of tower outer frame corner column is 3 000mm 脳 17 650mm, and the inner and outer distribution of steel tube column of composite structure is high strength super. Large diameter dense steel bar, The single closed stirrups are the longest 25m, and the construction is very difficult. This project uses BIM technology to deepen the design ahead of time, optimize the installation mode of steel bar, self-made double channel steel formwork back corrugated, create the high strength concrete construction sequence in winter, and save the construction cost. The expected effect has been achieved.
