Construction method of large-span special-shaped double-curved-surface facing fair-faced concrete
The invention provides a large-span special-shaped double-curved-surface facing bare concrete construction method, and belongs to the technical field of concrete construction.The large-span special-shaped double-curved-surface facing bare concrete construction method comprises the following steps that construction preparation is conducted; modeling the large-span special-shaped hyperboloid structure, and exporting a two-dimensional drawing; positioning and paying off on site; splicing and adjusting the inner template and the outer template on site; an exposed joint strip is installed at the position, where the construction joint is located, of the inner side of the outer formwork; the inner formwork and the outer formwork are bound and fixed through steel bars and binding wires; bare concrete is continuously poured between the inner formwork and the outer formwork; the steel bars, the binding wires, the outer formwork, the exposed joint strips and the inner formwork are sequentially removed, and curing and surface treatment are conducted on the formed bare concrete; the method can solve the problem that when the formwork is dismantled, the edge of the exposed joint is cracked due to uneven formwork dismantling force caused by improper operation, and the situation that the construction difficulty is increased and the construction efficiency is affected due to the fact that gaps in the edge are filled is avoided.
本发明提供了一种大跨度异形双曲面饰面清水混凝土施工方法，属于混凝土施工技术领域，该大跨度异形双曲面饰面清水混凝土施工方法包括以下步骤：施工准备；对大跨度异形双曲面结构建模，导出二维图纸；现场定位放线；在现场进行内模板、外模板的拼装以及调整；在外模板的内侧施工缝所在的位置安装明缝条；使用钢筋和扎丝对内模板、外模板进行绑扎固定；在内模板、外模板之间连续浇筑清水混凝土；依次拆除钢筋和扎丝、外模板、明缝条以及内模板，对成型后的清水混凝土进行养护和表面处理；本发明可以解决在拆除模板时极易由于操作不当导致拆模力度不均使得在明缝部位出现边缘崩裂的问题，避免填补边缘的缺口导致增大施工难度，影响施工效率。
