ATa型板式楼梯施工工艺与工程应用

On construction craft and engineering application of ATa cranked slab stairs

结合工程案例,探讨了ATa型板式楼梯的施工工艺,介绍了其配合比设计与工艺流程,着重对支模顺序、钢筋绑扎、滑动支座施工等技术方法作了论述,并提出了确保施工质量的技术措施,经施工验证效果良好,梯段板拆模后表面光滑整洁且预埋件钢板位置准确,符合质量验收评定标准。

Combining with engineering cases, the paper explores the construction craft of ATa cranked slab stairs, introduces its proportional ratio design and craft procedure, indicates the technical methods of the formwork order, reinforced banding, sliding support construction, and points out the technical measures to ensure the construction quality, and illustrates the proof effect if better with smooth and tidy smooth after the form removal of bench plates, accurate position of embedded steel plate, and it adheres to the quality acceptance evaluation standards.
