Nuclear power station steel arch roof structure and assembly construction method thereof
The invention discloses a nuclear power station steel arch roof structure and an assembly construction method thereof. The steel arch roof structure is characterized in that arch main beams are distributed in parallel at intervals and are connected through arch secondary beam units to form an arch roof framework, and a roof structure panel is welded on the upper surface of the arch roof frameworkto form a sealed steel arch roof structure. The steel arch roof structure assembly construction method comprises the steps of arch main beam plane assembly part assembly, assembly supporting system arrangement, main beam plane assembly part and four tubular column support vertical assembly, arch main beam vertical assembly, arch secondary beam unit assembly, positioning precision adjustment, archroof framework assembly, roof structure panel assembly and whole arch roof assembly, and finally assembly supporting system and assembly positioning system disassembly, so that the steel arch roof structure is assembled finally. The assembly construction method can remarkably reduce structural deformation, simplify construction procedures, improve installation precision and improve construction efficiency, and can be applied to the field of building construction of the same type of structure.
本发明公开了一种核电站钢拱形屋面结构及其组装施工方法，钢拱形屋面结构的拱形主梁平行间隔分布并通过拱形次梁单元连接组成拱形屋面骨架，屋面结构面板焊接在拱形屋面骨架上表面，形成密封的钢拱形屋面结构。钢拱形屋面结构组装施工方法通过拱形主梁平面组装件组装、组装支撑系统布置、主梁平面组装件与四管柱支撑垂直组装、拱形主梁垂直组装、拱形次梁单元组装、定位精度调节，拼装拱形屋面骨架、屋面结构面板组装和整个拱形屋面组装，最后拆除组装支撑系统和组装定位系统，最终组装成钢拱形屋面结构；本组装施工方法可显著降低结构变形、简化施工工序、提高安装精度、提升施工效率，可应用于同类型结构的建筑施工领域。
