Arch rib side section rotating body and middle section suspended lifting installation construction method
The invention relates to an arch rib side section rotation and middle section suspension installation construction method. An arch rib is divided into two side sections and a middle section; edge section and middle section arch rib assembling supports are erected respectively, and meanwhile edge section vertical rotating systems are installed on the skewbacks; the side section arch ribs and the middle section arch ribs are synchronously assembled on the support, after the side section arch ribs are assembled, a hoisting scaffold system is installed at the front ends of the side section arch ribs, and stress point positions are reinforced; after the arch ribs on the two side sections are rotated in place, the middle section of the arch rib is lifted through the scaffold to be closed with the two side sections. Compared with an existing construction method, the construction method is short in construction period, high in safety and low in cost.
本发明涉及一种拱肋边段转体及中段悬提安装施工方法，将拱肋划分两个边段和一个中段；在分别搭设边段和中段拱肋拼装支架，同时在拱座上安装边段竖转体系；在支架上同步拼装边段拱肋和中段拱肋，边段拱肋拼装完成后，在其前端安装起重鹰架系统，并对受力点位进行加固；将两边段拱肋转体到位后，通过鹰架提升拱肋中段与两边段合龙。本发明相比现有施工方法，工期短，安全性高，成本低。
