The invention discloses a steel structure roof sliding X-shaped jig frame and a jacking method thereof, the whole steel structure roof sliding X-shaped jig frame is in a butterfly shape, and the steel structure roof sliding X-shaped jig frame comprises two triangular parts which are symmetrically arranged and connected with each other; the two triangular parts are completely the same in structural shape and are fixedly connected through a connecting and fixing point; the jig frame is formed by splicing frame-shaped unit frames. The steel structure roof sliding X-shaped jig frame is reasonable in overall structural design, compared with a traditional flat-plate-shaped structure, the notches are formed in the two sides in the moving direction, hoisting of roof truss components on the jig frame can be greatly facilitated, rod clamping is avoided, the design is universal, the requirements of different sliding directions can be met, and the construction efficiency is improved. The requirement for hoisting equipment under the condition of the prior art is reduced, the cost is reduced, the working efficiency is improved, meanwhile, the stability of the whole structure is good, the bearing requirement for the heavy roof truss can be met, the profile is formed by splicing straight lines, the requirement for the splicing technology is low, and the application prospect is extremely high.

本发明公开了一种钢结构屋面滑移X型胎架及其顶升方法，整体呈蝶形，其包括对称布置且相互连接的两三角形部；两三角形部的结构形状完全相同且两三角形部通过连接固定点固定连接；胎架由框状单元架拼接而成。本发明的钢结构屋面滑移X型胎架，整体结构设计合理，其相比于传统的平板状结构，移动方向的两侧开有缺口能够大大方便对胎架上屋架构件的吊装，避免卡杆，此为通用型设计，可适应不同滑移方向的需要，降低现有技术条件下对吊装设备的要求，降低成本，提高工作效率，同时整体结构的稳定性较好，能够满足对重型屋架的承载要求，其轮廓由直线拼接而成，对拼接工艺要求较低，极具应用前景。
