Further, the upper end face of the main beam upper flange and the upper end face of the secondary beam upper flange are located on the same horizontal plane. Both can be installed on the building structure or construction equipment at the construction site at the same time.
Further, the upper flange, the lower flange and the web plate of the girder are integrally formed H-shaped steel.
The main beam lower flange in the composite beam is used as a traveling track for smooth passage of the hoisting mechanism, and transverse reinforcing ribs and longitudinal reinforcing ribs are arranged on the web plate of the main beam so as to enhance the tensile strength of the composite beam. Even if the travelling rail is locally damaged, the bearing capacity of the beam can still ensure the safety of the whole structure. In the actual use process, the travelling rail and the longitudinal reinforcing ribs are pulled together, so that the construction safety is ensured.
