Assembling and mounting of steel truss of super large span roof are analyzed. Steel truss factory prefabricated parts are used. An overall jig frame is sectionally assembled on site and lifted after being assembled in sections. Then, it is assembled in place in a mode that a temporary support jig frame is erected on site, so that large lifting and transportation equipment can be reduced. Thus, the cost is saved and the construction period is shortened.
