Orthotropic steel bridge deck ductile concrete composite structure and construction method
The invention discloses an orthotropic steel bridge deck ductile concrete composite structure and a construction method, and relates to the technical field of bridge engineering. The key points of thetechnical scheme are as follows: the orthotropic steel bridge deck ductile concrete composite structure comprises an orthotropic steel bridge deck, a grid mesh and a tough concrete layer; a pluralityof longitudinal ribs are transversely arranged on the bottom surface of the steel bridge deck at intervals; shear nails are arranged on the top surface of the steel bridge deck; a plurality of criss-cross erecting rib perforated plates are arranged on the top surface of the steel bridge deck at equal intervals; and an SBS modified asphalt SMA pavement layer is paved on the top surface of the tough concrete layer. The combined structure can improve the overall rigidity of the steel bridge deck and improve the fatigue problem of the steel bridge deck system and has the advantages of light self-weight, high bearing capacity and simple structure, and can ensure that the steel bridge deck has a wide application range and good stress performance under various conditions; bridge construction cost is saved, and benefits are remarkable. The national key research and development plan subsidy is obtained, the subject name is the key technical research of the efficient construction of the combined structure urban bridge, and the subject number is 2017YFC070348.
本发明公开了一种正交异性钢桥面板韧性混凝土组合结构及施工方法，涉及桥梁工程技术领域，其技术方案要点是：包括正交异性钢桥面板、格栅网和韧性混凝土层；钢桥面板底面设有横向间隔的多个纵向肋骨；钢桥面板顶面设有剪力钉；钢桥面板顶面等间隔设有纵横交错的多个架立筋开孔板；韧性混凝土层顶面铺设有SBS改性沥青SMA铺装层。该组合结构能提高钢桥面的整体刚度，改善钢桥面体系的疲劳问题，且具自重轻、承载力高、构造简单的优点，且能保证钢桥面在各种条件下具备广阔的适用范围与良好的受力性能；节约桥梁建造成本，效益显著。本发明已经获得国家重点研发计划资助，课题名称为：组合结构城市桥梁高效施工关键技术研究，课题编号为：2017YFC070348。
