Novel structure adopting assembly type transverse multi-piece small box girder
The invention discloses a novel structure adopting a plurality of assembled transverse small box girders, which comprises two or more small box girders arranged side by side, a beam top precast slab is arranged at the top of each small box girder, and an inter-beam precast slab is arranged between every two adjacent small box girders; the small box girders can reduce the erection weight and enhance the transverse connection strength at the same time; the small box girders are fixedly connected with the beam top precast slabs and the inter-beam precast slabs through embedded steel bolts, filling agents are further arranged between the small box girders and the beam top precast slabs and between the small box girders and the inter-beam precast slabs for cementing, and shear key structures are arranged at the tops of the small box girders; a bridge deck cast-in-place layer is arranged on the tops of the beam top prefabricated slabs, the beam-to-beam prefabricated slabs and the small box girders, and the shear key structures are embedded in the tops of the small box girders and extend into the bridge deck cast-in-place layer. Compared with the prior art, the method has the advantages that the structure is clear, construction is convenient, the stability and safety of small box girder construction can be improved, the influence on electrified railways, roads or structures is reduced, and the blocking and control time of the railways or the roads is greatly shortened.
本发明公开了一种采用装配式横向多片小箱梁的新型结构，包括两个及以上并排设置的小箱梁，小箱梁顶部设有梁顶预制板，相邻两个小箱梁之间设有梁间预制板；小箱梁能够减轻架设重量，同时可以增强横向连接强度；小箱梁与梁顶预制板、梁间预制板通过预埋钢螺栓连接固定，小箱梁与梁顶预制板、梁间预制板之间还设有填充剂胶结，小箱梁顶部设有剪力键结构；梁顶预制板、梁间预制板、小箱梁顶部设有桥面现浇层，剪力键结构预埋在小箱梁顶部，伸入桥面现浇层内部。本发明与现有技术相比的优点在于：结构明确，施工方便，能够提高小箱梁施工的稳定性和安全性，减少对电气化铁路、公路或构筑物的影响，大大缩短铁路或者公路的封锁管制时间。
