Construction method of large-span structure
The invention belongs to the technical field of constructional engineering, and discloses a construction method of a large-span structure, which comprises the following steps: firstly, splicing the large-span structure on the ground, then lifting the large-span structure to a set elevation through a lifting device, temporarily connecting the large-span structure with a tower structure, and providing horizontal constraint through the tower structure. The large-span structure can keep certain overall stability after lifting operation, on the basis, the two ends of the supporting piece are connected with the large-span structure and the ground correspondingly, then vertical constraint is provided for the large-span structure, the large-span structure is supported so that the stability of the large-span structure can be further improved, and an operator jacks the large-span structure through the jacking device; and a jacking force is applied to the large-span structure through the jacking device, so that the stress and deformation of the structure are regulated and controlled to meet the design requirements. And after the stress and deformation of the large-span structure are regulated and controlled, the large-span structure is permanently connected with the tower structure, and the lifting device and the supporting piece are dismounted, so that the mounting operation of the large-span structure is completed.
本发明属于建筑工程技术领域，公开了一种大跨结构的施工方法，首先在地面拼装大跨结构，然后通过提升装置将大跨结构提升至设定标高，将大跨结构与塔楼结构进行临时连接，通过塔楼结构提供水平约束，使得大跨结构能够在提升作业后保持一定的整体稳定性，在此基础上，通过支撑件的两端分别与大跨结构和地面连接，进而对大跨结构提供竖向约束，进而支撑大跨结构以进一步提高其稳定性，作业人员通过顶升装置顶升大跨结构，通过顶升装置施加顶推力至大跨结构上，以调控结构应力和形变至设计要求。待大跨结构的应力和形变调控完毕后，将大跨结构与塔楼结构永久性连接，并拆除提升装置和支撑件，从而完成了大跨结构的安装作业。
