| 摘 要： | 上海华敏帝豪大厦是一座高235.1 m的60层综合大厦。框架柱采用矩形钢管混凝土柱,内灌自密实混凝土。为了提高施工工效,打破了CECS 203:2006《自密实混凝土应用技术规程》第7.3.7条"浇筑混凝土时的最大自由落下高度宜在5 m以下"的规定。采用了缩短导管,直接浇灌混凝土的方法,提高了工效。同时,对减少内隔板下面的气泡,采取有效措施,保证了工程质量。

| Abstract: | Dihao Super Tall Building in Shanghai is a higher synthetically building.In which the rectangular concrete filled steel tubular columns are adopted as frame columns.The self-compacting concrete is used.The 7.3.7 item in "Technical Specification Applied to Self-Compacting Concrete" shows that stipulation of the free drop height of concrete is not over 5 m.And this stipulation is broken,a short leading pipe is used to pour concrete into steel tube,then the work efficiency is raised.As well as,some effective m... |
