Steel-concrete combined open box girder structure and laying method thereof
The invention discloses a steel-concrete combined open box girder structure and a laying method thereof, and belongs to the technical field of bridge design. The structure comprises an inverted-U-shaped steel channel beam, a lightweight concrete plate and studs, the studs are installed at the top of the inverted-U-shaped steel channel beam, installation holes are machined in the lightweight concrete plate, the lightweight concrete plate is installed on the inverted-U-shaped steel channel beam, the studs are arranged in the installation holes, and meanwhile high-strength concrete is poured in the installation holes. The invention aims to solve the technical problems that the construction cost of a prefabricated assembly type concrete beam is too high, prefabricated parts are too heavy, the number of welding seams of a prefabricated assembly type steel-concrete composite beam is too large, early-stage damage is likely to happen to steel box beam bridge deck pavement, and later-stage maintenance is inconvenient, the construction cost of a prefabricated assembly type bridge is greatly reduced, and the construction period is shortened. According to the inverted U-shaped channel steel rolling forming technology, the number of welded joints of the box girder is greatly reduced, then the probability of fatigue damage of the steel box girder caused by residual stress generated by welding is greatly reduced, and the safety of a bridge is greatly improved.
一种钢‑混组合开口箱梁结构及其铺设方法，属于桥梁设计技术领域。本发明包括倒U形槽钢梁、轻质混凝土板和栓钉，倒U形槽钢梁顶部安装有栓钉，轻质混凝土板上加工有安装孔，轻质混凝土板安装在倒U形槽钢梁上，栓钉置于安装孔内，同时安装孔内浇注有高强混凝土。本发明研发目的是为了解决预制装配式混凝土梁建设成本过高、预制构件过重以预制装配式钢‑混凝土组合梁焊缝过多、钢箱梁桥面铺装易发生早期破坏、后期养护不便的技术问题，本发明大大降低预制装配式桥梁建设成本，倒U形槽钢辊压成型技术，大大减少箱梁焊接缝数量，进而大大降低了因焊接产生残余应力而造成的钢箱梁疲劳损伤发生几率，桥梁的安全性得到大大提高。
