Large-span high-loading-capacity aluminum alloy rail

The utility model relates to the technical field of aluminum alloy rails, in particular to a large-span high-loading-capacity aluminum alloy rail, which comprises vertical reinforcing ribs, supporting plates and reinforcing plates, and has the beneficial effects that a plurality of vertical reinforcing ribs are uniformly arrayed on the inner wall between an upper plate and a lower plate of a rail base body, so that the strength of the rail base body in the vertical direction is enhanced; the supporting plate is fixed between the bottom end of the rail groove and the middle position of the upper side of the bottom end of the rail base body, the bearing capacity of the rail groove is improved, and the situation that the normal use effect of the rail is affected due to the fact that the rail is bent due to too large gravity and the inverted door body droops is prevented; the reinforcing plates are installed and rotated to achieve the function of enhancing the strength of the rail base body. 本实用新型涉及铝合金轨道技术领域，具体为一
