Orthotropic steel bridge deck slab and ultra-high performance concrete combined bridge and construction method thereof
The invention discloses an orthotropic steel bridge deck slab and ultra-high performance concrete combined bridge. The bridge comprises a bridge deck and a steel main beam, wherein the bridge deck isan ultra-high performance concrete combined bridge deck slab; the ultra-high performance concrete combined bridge deck slab comprises an orthotropic steel bridge deck slab and an ultra-high performance concrete deck slab, the orthotropic steel bridge deck slab comprises a steel bridge deck slab and longitudinal stiffening ribs welded to the lower plate face of the steel bridge deck slab. The steelbridge deck slab is welded with the steel main beam, so that the steel main beam forms a closed steel box girder or a plate girder or a bilateral box girder or a steel truss girder, a plurality of shear nails extending into the ultra-high performance concrete slab are welded on the upper plate surface of the steel bridge deck slab, and an upper edge stressed reinforcing mesh is arranged on the upper edge in the ultra-high performance concrete panel. The bridge deck slab of the combined bridge is high in tensile strength and compressive strength, reliable in connection, good in durability andlow in manufacturing cost. The invention further discloses a construction method of the combined bridge, the combined bridge is constructed in a segmented mode, and construction is more convenient.
本发明公开了一种正交异性钢桥面板与超高性能混凝土组合桥，其包括桥面和钢主梁，桥面为超高性能混凝土组合桥面板，超高性能混凝土组合桥面板包括正交异性钢桥面板以及超高性能混凝土面板，正交异性钢桥面板包括钢桥面板和焊接在钢桥面板的下板面的纵向加劲肋，钢桥面板与钢主梁相焊接，使得钢主梁形成封闭钢箱梁或板梁或双边箱梁或钢桁梁，在钢桥面板的上板面焊接有若干个伸入超高性能混凝土面板内的剪力钉，在超高性能混凝土面板内部上缘设有上缘受力钢筋网。本发明的组合桥的桥面板抗拉和抗压强度高、连接可靠、耐久性好且造价较低。本发明还公开了组合桥的施工方法，其将组合桥进行分段施工，施工更方便。
