The utility model relates to the field of rail transit power supply equipment, in particular to a large inertia moment busbar for a railway contact network. The large-inertia-moment busbar for the railway contact network is used for fixing a contact line located above a train pantograph and comprises a busbar body, the busbar body comprises a connecting plate, clamping walls and a partition plate, the two oppositely-arranged clamping walls are fixed to the plate face of one side of the connecting plate, the contact line is jointly clamped by the ends, away from the connecting plate, of the two clamping walls, and the partition plate is arranged between the two clamping walls. A partition plate is fixed between the two clamping walls, and the partition plate, the connecting plate and the two clamping walls jointly define a cavity. And the two sets of inserting plates are arranged, the two sets of inserting plates are limited between the two clamping walls, and the plate faces of the two sets of inserting plates abut against the inner side walls of the two clamping walls correspondingly. At least one contact protrusion is arranged on the inner wall of the clamping wall, and the contact protrusion abuts against the inserting plate at an inclined angle.

The invention relates to a parallel loading wing type large-span cantilever truss structure system and a mounting method thereof, the structure system is formed by connecting a plurality of loading wing type trusses which are arranged along the outer edge of a main body structure in parallel at intervals and unfolding wing type trusses on the outermost side in parallel, and the trusses are connected into a space whole through horizontal connecting components. The wing carrying type truss comprises a vertical bearing part and a horizontal overhanging part which are inclined from inside to outside, a wing carrying structure is formed, and overhanging loads are efficiently and obliquely transmitted to a main body structure. Reinforcing components such as three-fork web members are arranged at the ends of the wing-unfolding type trusses, and the rigidity of the ends is enhanced. The mounting method adopts sequential construction of pushing truss by truss from one end to the other end and synchronously connecting horizontal members. The problems that a traditional solid-web cantilever beam is huge in dead weight, insufficient in rigidity and large in building space occupation are solved, and the large-span solid-web cantilever beam has the advantages of being reasonable in stress, small in steel consumption, large in spanning capacity and wide in building space and is suitable for large-span cantilever buildings such as stadiums and terminal buildings.
