Profiled steel sheet assembly type combined box bridge
The invention discloses a profiled steel sheet assembly type combined box bridge. The profiled steel sheet assembly type combined box bridge is composed of profiled steel sheet prefabricated parts, a box main body structure and ultrahigh-toughness concrete. The profiled steel sheet prefabricated parts have two forms, longitudinal shearing force and upward pulling force between the profiled steel sheet prefabricated parts and the ultrahigh-toughness concrete are resisted through round steel bars and inter-hole steel plates, and transverse steel bars or studs do not need to be additionally welded to the profiled steel sheet. The profiled steel sheet prefabricated parts and the box main body structure are connected through high-strength bolts to form an assembled box bridge steel framework, and stiffening ribs do not need to be additionally welded to a bridge deck top plate. According to the profiled steel sheet assembly type combined box bridge, the structural bearing capacity, the fatigue performance, the toughness and the durability are improved, meanwhile, the construction complexity and the material cost are greatly reduced, and meanwhile the system has the potential of application and popularization due to the high-prefabrication assembly characteristic.
本发明公开了一种压型钢板装配式组合箱型桥，由压型钢板预制件，箱型主体结构和超高韧性混凝土组成。压型钢板预制件包含两种形式，均通过圆钢棒和孔间钢板抵抗与超高韧性混凝土之间的纵向剪力和上拔力，无需在压型钢板上额外焊接横向钢筋或栓钉。压型钢板预制件和箱型主体结构之间通过高强螺栓连接后形成装配式箱型桥钢骨架，无需在桥面顶板上额外焊接加劲肋。本发明提出的压型钢板装配式组合箱型桥在使结构承载力、疲劳性能、韧性以及耐久性提升的同时大大降低了施工复杂度和材料成本，同时该体系高预制装配化特点也使其具备推广应用的潜质。
