Embodiment Construction
[0021] Below in conjunction with accompanying drawing, structure of the present invention, construction process are described further.
[0022] Compared with the traditional composite box girder deck system of cable-stayed bridges, the present invention provides less on-site workload and construction difficulty, easy guarantee of concrete pouring quality, higher structural bearing capacity, rigidity and crack resistance, and better economic performance Corrugated steel web composite box girder deck system of a cable-stayed bridge. Such as Figure 2 to Figure 7 As shown, the structure includes the steel box girder part of the composite box girder welded by the corrugated steel web 2, the upper flange steel plate 1, and the box girder bottom steel plate 4, and the box girder floor stiffener 5 is welded in the steel box girder And the diaphragm, the diaphragm includes the flange steel plate 6 on the diaphragm and the steel web 7 of the diaphragm; the stud connection is welded on...
