Installation and construction method for large-span steel structure dome in limited space
The invention relates to an installation construction method for a large-span steel structure dome in a limited space, and relates to the technical field of dome construction. The installation construction method comprises the following steps: step 1, designing and assembling a jig support; secondly, a supporting frame is erected, different standard knot stand columns of the same section are connected through connecting rods, and the multiple sections of standard knot stand columns are lifted to the elevation of the bottom of a dome cross beam; thirdly, an inner ring beam is installed, hoisting construction is conducted on all sections of the inner ring beam in sequence, and welding is conducted after hoisting is conducted in place; fourthly, curved-surface main beams are installed, hoisting of the south-north longitudinal curved-surface main beams and the east-west longitudinal curved-surface main beams is completed, and then installation work of other curved-surface main beams is conducted in sequence; 5, mounting an outer ring beam and a curved surface secondary beam; the method is suitable for construction of the large-span and overweight dome steel structure, a combined assembly type steel beam supporting system is adopted, assembly of all components of the steel structure is conducted in sequence in the limited space, and the requirement for aerial assembly construction of the large-span dome steel structure under the space limited condition can be met.
本发明涉及一种受限空间内的大跨度钢结构穹顶安装施工方法，涉及穹顶施工的技术领域，包括以下步骤：步骤一、胎架支撑设计拼装；步骤二、支撑架搭设，使用连杆连接同一段的不同标准节立柱，多段标准节立柱提升至穹顶横梁底部标高；步骤三、内环梁安装，依次对内环梁各段进行吊装施工，吊装就位后进行焊接；步骤四、曲面主梁安装，完成南北和东西纵向曲面主梁的吊装，然后依次进行其他曲面主梁的安装工作；步骤五、外环梁及曲面次梁安装；步骤六、胎架支撑拆除，本发明适用于大跨度，超重穹顶钢结构施工，采用组合装配式钢梁支撑体系，在受限空间内依次进行钢结构各构件的拼装，能满足空间受限条件下的大跨径穹顶钢结构空中拼装施工。
