The invention relates to the technical field of constructional engineering design, and particularly discloses a wind-resistant column and roof connecting node suitable for a large-span steel structure roof, which comprises a steel connecting rod arranged between a steel roof truss and a steel gable wind-resistant column; the two ends of the steel connecting rod are rotationally connected with the steel roof truss and the steel gable wind-resistant column correspondingly. The anti-deformation reinforcing method for the gable column is suitable for a large-span steel structure, the stress of the wind-resistant column of the steel gable can be transmitted to a roof truss system under the condition of large deformation of the roof truss, meanwhile, the wind-resistant column of the steel gable cannot limit deformation of the roof truss, and the anti-deformation reinforcing method has the advantages of being clear in structural stress, safe, reliable and convenient to construct and install.

本发明涉及建筑工程设计技术领域，具体公开了一种适用于大跨度钢结构屋盖的抗风柱与屋盖连接节点，包括在钢屋架与钢山墙抗风柱之间安装钢连杆；所述钢连杆的两端分别与钢屋架、钢山墙抗风柱转动连接。本发明公开的山墙柱防变形加固方法适用于大跨度钢结构中，能够满足在屋架大变形情况下，钢山墙抗风柱受力向屋架系统的传递，同时钢山墙抗风柱也不会限制屋架的变形，具有结构受力明确，安全可靠的特点，同时，便于施工安装。
