本刊讯(通讯员和楠刘国英)9月1日,中国第一高楼——深圳平安国际金融中心项目核心筒B5层A1段钢板剪力墙混凝土开始浇筑,此次浇筑的核心筒剪力墙最厚区域达1.5米,一次浇筑高度达4.35米,约278立方米。浇筑的部分在超高层项目中属超厚组合结构墙体,由于钢板剪力墙墙体较厚、钢筋密集,对混凝土的性能和模板体系要求较高,属于该工程的难点之一。在项目部周密的技术方案准备下,浇筑的混凝土密实均匀,流动性和工作性能较好。此次混凝土浇筑顺利的完成,为后续主塔楼核心筒爬模及高标号混凝土施工奠定了基础。浇筑现场
September 1, the first high-rise building in China - Shenzhen Ping An International Financial Center project core tube B5 layer A1 section of steel shear wall began pouring concrete, the core of the core wall of the most shear wall pouring Thick area of 1.5 meters, a pouring height of 4.35 meters, about 278 cubic meters. Pouring part of ultra-high-rise projects in the ultra-thick composite structure of the wall, due to thicker steel sheet wall shear, reinforced intensive, high performance requirements of the concrete formwork and the system is one of the difficulties. In the project department and careful preparation of the technical program, the pouring of concrete dense, fluid and good performance. The successful completion of the concrete pouring for the follow-up of the core tower core climbing and high-grade concrete laid the foundation. Pouring the scene
