Fabricated beam bridge structure with longitudinally mixed steel plate composite beam and concrete T beam and construction method of fabricated beam bridge structure
The invention discloses a steel plate composite beam and concrete T beam longitudinally-mixed fabricated beam bridge structure and a construction method thereof.The steel plate composite beam and concrete T beam longitudinally-mixed fabricated beam bridge structure is formed by longitudinally connecting a steel plate composite beam section, a concrete T beam section and a mixed section, the steel plate composite beam section is arranged in a beam span, and the concrete T beam section is arranged in a beam support area; the mixed section is connected with the steel plate composite beam section and the concrete T-beam section, the steel plate composite beam section is formed by combining lower edge I-shaped steel, steel-concrete connecting shear nails and an upper edge concrete bridge deck on the same cross section, and the mixed section is formed by connecting a steel plate composite beam with a T-beam concrete web through a steel web according to an inclined plane of 20-75 degrees. Compared with an existing concrete T beam, the fabricated hybrid beam bridge has the advantages of being higher in spanning capacity and better in stress performance; compared with an existing steel plate composite beam, the steel plate composite beam has the advantages of being better in shear resistance and stability. And the construction requirements of simply supported girder bridges and continuous girder bridges can be met.
本发明公开了一种钢板组合梁与混凝土T梁纵向混合的装配式梁桥结构及其施工方法，由钢板组合梁区段、混凝土T梁区段和混合区段三部分在纵向连接组成，钢板组合梁区段设置在梁跨中，混凝土T梁区段设置在梁支座区域，混合区段连接钢板组合梁区段和混凝土T梁区段，钢板组合梁区段由下缘工字钢、钢混连接剪力钉、上缘混凝土桥面板三部分在同一横断面组合形成，混合区段由钢板组合梁按照20°‑75°斜面由钢腹板与T梁混凝土腹板连接。本发明的装配式混合梁桥相对于现有混凝土T梁具有跨越能力更大、受力性能更好的优点；相对于现有钢板组合梁具有抗剪性能更好、稳定性更佳的优点；能够适应简支梁桥和连续梁桥的建设需求。
