Steel-UHPC combined rod piece truss girder bridge and construction method thereof
The invention discloses a steel-UHPC (Ultra High Performance Concrete) combined member truss girder bridge and a construction method thereof, the steel-UHPC combined member truss girder bridge comprises a plurality of truss girder bridge sections which are connected in sequence, and each truss girder bridge section comprises a pressed main chord member for bearing pressure, a steel pulled main chord member for bearing pulling force, a steel flat bracing, a steel cross beam and a steel web member; the pressed main chord member comprises a box-shaped steel inner shell and a UHPC box-shaped outer shell wrapping the box-shaped steel inner shell, the UHPC box-shaped outer shell is tightly attached to the outer surface of the box-shaped steel inner shell and connected with the outer surface of the box-shaped steel inner shell through a shearing force connecting piece connected to the box-shaped steel inner shell, and the box-shaped steel inner shell is made of a high-strength steel plate. The steel-UHPC combined rod piece truss girder bridge has the advantages of being reasonable in stress, easy and convenient to construct and good in economical efficiency.
本发明公开了一种钢‑UHPC组合杆件桁梁桥及其施工方法，包括多个依次连接的桁梁桥节段，桁梁桥节段包括用于承受压力的受压主弦杆、用于承受拉力的钢受拉主弦杆、钢平联、钢横梁以及钢腹杆，受压主弦杆包括箱型钢内壳和外包箱型钢内壳的UHPC箱型外壳，UHPC箱型外壳与箱型钢内壳外表面紧密贴合并通过连接在箱型钢内壳上的剪力连接件进行连接，箱型钢内壳采用高强钢板。该钢‑UHPC组合杆件桁梁桥具有受力合理、施工简便、经济性好的优点。
