Embodiment Construction
[0036] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0037] Adopting the structural form of integral portal rigid frame flyover with one side consolidated and one side hinged instead of the traditional simply supported steel box girder flyover structure can significantly increase the fundamental frequency of the vertical vibration of the upper structure of the flyover, avoid resonance, greatly reduce the girder height, and improve landscape effect. The hinged structure of the steel pier column and the cap on one side, as an important connecting member between the steel pier column structure and the concrete cap in the portal frame bridge structure, needs to reliably transmit all the internal forces of the superstructure to the cap.
[0038] Such as Figure 1 to Figure 4 As shown, this embodime...
