Thin-wall cavity multi-curve fair-faced concrete arch pouring formwork construction method
The invention discloses a thin-wall cavity multi-curve bare concrete arch pouring formwork construction method. The method comprises the following steps that S1, an arch is divided into a plurality of sections, and a steel outer formwork is customized according to the sections; s2, according to the design size of the arch cavity, a plurality of filling limiting plates are evenly arranged on the arc-shaped steel beams; s3, gaps between the filling limiting plates and the arc-shaped steel beams are filled with extruded sheets, and the adjacent extruded sheets adhere to form a pouring inner mold; s4, the pouring inner mold is supplemented, trimmed and polished, so that the two sides and the bottom of the pouring inner mold are smooth curved surfaces; s5, the pouring inner mold is fixed and positioned through an opposite-pull screw rod; s6, the filling limiting plate is dismantled, and the pouring inner mold is wrapped with a fireproof and waterproof film; s7, the outer wall of the pouring inner mold serves as a datum plane, and two or more layers of reinforcing meshes are laid on the outer portion of the pouring inner mold; and S8, the customized steel outer formwork is fixedly installed on the outer portion of the reinforcing mesh on the outermost side.
本发明公开了一种薄壁空腔多曲清水混凝土拱券浇筑模板施工方法，包括以下步骤：S1、将拱券分为多个节段并据此定制钢制外模板；S2、根据拱券空腔的设计尺寸，在所述弧形钢梁上均匀排布设置多块填充限位板；S3、使用挤塑板对所述填充限位板与所述弧形钢梁之间的间隙进行填充，相邻挤塑板粘连形成浇筑内模；S4、对所述浇筑内模进行增补和修剪打磨，使其两侧及底部呈平滑曲面；S5、使用对拉螺杆对浇筑内模进行固定和定位；S6、拆除所述填充限位板，使用耐火防水膜包裹在所述浇筑内模的外部；S7、以所述浇筑内模的外壁为基准面，在其外部铺设两层或两层以上钢筋网片；S8、将定制的所述钢制外模板固定安装在最外侧所述钢筋网片的外部。
