Manufacturing and mounting method for outer tank steel dome of large low-temperature storage tank
The invention provides a manufacturing and mounting method for an outer tank steel dome of a large low-temperature storage tank. Comprising the following steps of prefabricated frame site arrangement, prefabricated frame design and manufacturing, steel dome beam plate prefabrication and assembly welding forming, dome module transfer, center and edge support installation, middle support installation and dome module hoisting in place, residual ring beam skin plate and track beam installation, sleeve stud accessory installation and center and middle support removal. According to the method, the unstressed assembly of the dome module beams, the dome camber keeping technology and the circular alternating stand column dismantling method for avoiding the tearing of the welding seams of the dome steel structure are researched, the construction method is formed through summarization, remarkable benefits are obtained in subsequent construction of multiple large low-temperature storage tanks, and the method is worthy of application and popularization.
本发明提供了一种大型低温储罐外罐钢穹顶的制作安装工法，包括以下步骤：预制架场地布置、预制架设计制作、钢穹顶梁板预制及组焊成型、穹顶模块转移、中心和边缘支撑安装、中间支撑安装及穹顶模块吊装就位、剩余环梁蒙皮板和轨道梁安装、套管螺柱附件安装、中心和中间支撑拆除。本发明研究出了穹顶模块梁的无应力组对、穹顶拱度保持技术和避免穹顶钢结构焊缝撕裂的循环交替立柱拆除法，通过总结形成本工法，在后续多台大型低温储罐建造中取得了显著效益，值得推广应用。
