超高层建筑无支撑钢筋桁架楼承板施工技术

Construction Technology of Unsupported Steel Bar Truss Deck in the Super Tall Building

以首旅大厦为工程背景,论述钢筋桁架楼承板施工技术在高层劲性混凝土框架-核心筒结构中的应用。分析钢筋桁架楼承板运输、存放、吊装、支撑角钢精准焊接固定、楼板洞口预留等施工工艺的重难点,提出相应的解决措施。重点阐述钢筋桁架楼承板主要施工流程及安全与质量控制要点。

Taking the Shoulü Building as the engineering background,the application of the construction technology of the steel bar truss deck in the high-rise steel reinforced concrete frame-core tube structure was discussed. This paper analyzed the heavy and difficult points of the construction technology such as transportation,storage, hoisting, precision welding and fixing of supporting angle steel, and the reservation of the floor hole,and put forward the corresponding solutions. The main construction process,safety and quality control points of the steel bar truss deck were emphatically described.
