Super-large-span frame provided with reinforced connecting structure and mounting process of super-large-span frame

The invention provides an ultra-large-span frame provided with a reinforcing connection structure and an installation technology of the ultra-large-span frame, and relates to the technical field of large-span frames. Comprising two sets of frame transverse strips and connecting vertical strips installed between the two sets of frame transverse strips, the multiple connecting vertical strips are evenly distributed in the two sets of frame transverse strips, lower reinforcing mechanisms are connected to the lower portions of the connecting vertical strips in a clamped mode, and L-shaped pressing plates are slidably connected to the left sides and the right sides of the lower reinforcing mechanisms; inclined connecting rods are movably installed on the upper portions of the L-shaped pressing plates located on the same side, upper reinforcing mechanisms are movably installed on the upper portions of the connecting rods, and the upper reinforcing mechanisms are connected with the intersections of the upper portion
