Bracket construction method for super-long side span cast-in-place section
The invention discloses a bracket construction method for a super-long side span cast-in-place section. The bracket construction method comprises the following steps that a construction platform is erected; two hole channels are drilled or reserved from one side of the pier body to the other side of the pier body in a matched mode at the bottom of the designed position of the bracket, a solid steel bar is inserted into each hole channel in a matched mode to serve as the lower cross beam of the bracket, and a lower bearing beam is installed and fixed on the solid steel bars on the same side; mounting a supporting structure above the lower bearing beam in the bracket; a bottom die and an operation platform of the box girder formwork are installed on the bracket; mounting a template bearing beam; a wing plate and an outer web supporting structure of the box girder formwork are installed; and concrete pouring of the side span cast-in-place section is conducted. By adopting the bracket with higher bearing capacity, the smooth construction of the super-long side span cast-in-place section is realized.
本发明公开了一种超长边跨现浇段的托架施工方法，包括以下步骤：搭设施工平台；安装托架的下横梁：在托架设计位置的底部，匹配从墩身一侧至另一侧钻取或预留两个孔道，每个孔道匹配插入一根实心钢棒作为托架的下横梁，在同侧的实心钢棒上面安装并固定下垫梁；安装托架中下垫梁以上的支撑结构；在托架上面安装箱梁模板的底模及操作平台；安装模板垫梁；安装箱梁模板的翼板和外腹板支撑结构；边跨现浇段的混凝土浇筑。本发明通过采用承载能力更大的托架，实现了超长边跨现浇段的顺利施工。
