This invention is a new type of bridge structure with a short erection time. The invention eliminates temporary supports and scaffoldings, and generates an aesthetical final product with the advantages of both a concrete bridge and a steel bridge. The invention may be used for car-, railroad-, bicycle- and pedestrian bridges or similar structures. The invention may also be used for temporary bridges, possible to disassemble. Between the main girders of the bridge (1), which are filled with concrete (2), a steel deck (3) is supported and connected to the bottom flanges (4) of the girders. On top of the steel deck a concrete slab (7) is cast. On top of the girder (1), which acts as a safety fence against collision in composite action with the concrete (2), an inclined railing (10) is connected, including a hand rail (11) that may be unspliced. |
