Truss-steel plate combined box girder and bridge and construction method
The invention relates to a truss-steel plate combined box girder, a bridge and a construction method, and the truss-steel plate combined box girder comprises a steel plate main girder part which comprises a steel bottom plate and a plurality of parallel steel plate girder groups vertically arranged on the steel bottom plate; the truss parts are arranged on the steel plate main beam part in parallel in the width direction of the steel plate main beam part; the upper chord member is used for being connected with the top of the steel plate beam group; the lower chord member is used for being connected with the bottom of the steel plate beam group; the large cantilever arm supporting inclined rod is connected with the end parts of the same sides of the upper chord member and the lower chord member; the plurality of vertical rod groups are vertically arranged between the lower chord member and the upper chord member; and the supporting inclined rod groups are obliquely arranged between the adjacent vertical rod groups and are connected with the upper chord and the lower chord. The bridge is formed by splicing a plurality of truss-steel plate combined box girders. Compared with the prior art, the truss-steel plate combined box girder has the advantages that under the condition that longitudinal and transverse stress reliability and local stability are guaranteed, the steel consumption is obviously reduced, and the economical efficiency is improved.
本发明涉及一种桁架‑钢板组合箱梁、桥及构建方法，所述桁架‑钢板组合箱梁包括：钢板主梁部，其包括钢底板、立设于所述钢底板上的若干平行的钢板梁组；若干沿所述钢板主梁部的宽度方向，平行设于所述钢板主梁部上的桁架部，其包括用于与所述钢板梁组顶部连接的上弦杆、用于与所述钢板梁组底部连接的下弦杆、与所述上弦杆和下弦杆同侧端部连接的大挑臂支撑斜杆、立设于所述下弦杆与所述上弦杆之间的若干竖杆组、以及斜设于相邻竖杆组之间并连接所述上弦杆和下弦杆的支撑斜杆组。所述桥由若干桁架‑钢板组合箱梁拼接组成。与现有技术相比，本发明的桁架‑钢板组合箱梁在保障纵横向受力可靠和局部稳定性的情况下，显著减小钢材用量，提高经济性。
