Assembling construction method for large steel structure roof
The invention relates to the field of building structures, and discloses an assembling construction method for a large steel structure roof, which comprises the following steps of: 1, assembling a secondary truss on the ground; 2, floor trusses are spliced; according to the method, the trusses are reasonably partitioned and spliced by adopting a method of splicing and then lifting the sub-trusses, and jig frame elevation control, linear control and welding deformation control are carried out on the small splicing units, so that high-precision and high-efficiency construction of large steel structure roof splicing is realized; and the connection error of various truss members in the splicing process is further reduced, and the mounting quality and precision of the steel structure roof truss are improved.
本发明涉及建筑结构领域，且公开了一种大型钢结构屋盖的拼装施工方法，该方法包括以下步骤：步骤一：进行次桁架地面拼装；步骤二：进行楼面桁架拼装；本发明通过采用分桁架拼装再提升的方法，对桁架进行合理分区拼装，并对小拼单元进行胎架标高控制、线型控制以及焊接变形控制，进而实现了大型钢结构屋盖拼装的高精度、高效率施工，进一步减小了拼装过程中各类桁架构件的连接误差，提高钢结构屋盖桁架的安装质量与精度。
