Steel-concrete mixed full-hollow continuous rigid frame bridge
The invention discloses a steel-concrete mixed full-hollow continuous rigid frame bridge. Comprising pier columns, open web areas arranged on the pier columns and solid web girder sections arranged between every two adjacent open web areas. Each hollow area comprises a lower chord member and an upper chord member; the longitudinal section of each lower chord member on the corresponding bridge is V-shaped, and the lowest point of each lower chord member is arranged at the upper end of the corresponding pier column; each upper chord is of a steel structure, the two ends of each upper chord are connected with the two ends of the corresponding lower chord respectively, and a cavity is formed between the lower surface of each upper chord and the upper surface of the corresponding lower chord. The end part, connected with the corresponding lower chord member, of each upper chord member is provided with a steel-concrete combined section, and a tie bar is arranged in the steel-concrete combined section. According to the application, the stress of the hollow area is improved, the material performance is fully played, the application range of the structural system is expanded, and the landscape effect of the structure can be further improved.
本发明公开了钢‑混凝土混合全空腹连续刚构桥梁；包括墩柱，设置在每一上的空腹区，以及设置在每两个相邻的空腹区之间的实腹梁段；每一空腹区均包括下弦杆和上弦杆；每一下弦杆在相应桥梁的纵截面均呈“V”字形，最低点均设置于相应的墩柱的上端；每一上弦杆均为钢结构，两端分别与相应的下弦杆的两端连接，下表面与相应的下弦杆的上表面之间形成空腔；每一上弦杆与相应的下弦杆连接的端部均设有钢混结合段，内部设有系杆。本发明的应用改善空腹区的受力，充分发挥材料性能，拓展该结构体系的适用范围，且能进一步提升结构的景观效果。
