预应力双T板在大型商业框架结构中的应用

The application of pre-stressed double T plate in large commercial frame structure

以国内首个大型预应力双T板PC框架结构商业综合体为背景,介绍了目前双T板在国内外的应用情况,论述了双T板、叠合板、SP预应力空心板三种方案的对比选择,对非国家标准图集的预应力双T板及搁置体系等进行了优化,最后通过本项目的应用与实施,总结出了预应力双T板在商业公共建筑应用的优缺点,可为今后同类工程设计及施工提供借鉴。

Taking the commercial complex of China＇s first large-scale pre-stressed double T plate PC frame structure as the background,this paper introduced the application situation of present double T plate at home and abroad,discussed the comparison and selection of double T plate,superimposed plate,SP pre-stressed hollow slab three schemes,optimized the non national standard atlas of pre-stressed double T plate and shelf system,finally through the application and implementation of the project,summarized the advantages and disadvantages of pre-stressed double T plate applied in commercial public buildings,provided reference for future similar engineering design and construction.
