摘要
针对某2m×24m为单元的预应力钢筋砼拱板并自带防水结构体的屋盖系统构件体积大、上下弦板砼厚度薄、自重大的特点,选用了"空中现浇法"施工,对施工方法进行了详细阐述。结果表明该工艺确保了施工质量。
The roof system is of prestress reinforced arch bar with waterproof structure body taking 2?m×24?m as unit,in view of the characteristics of large volume of roof system components and small thickness and big deadweight of upper and lower boom plate,the'concrete casting insitu from high platform'construction was selected,and the construction method was described in detail.The result shows that this technique guarantees the construction quality.
