Fabricated transverse connecting structure applied to small box girder
The invention discloses an assembly type transverse connection structure applied to small box girders, which comprises two or more small box girders arranged side by side, an inverted convex precast slab is arranged between two adjacent small box girders, and the tops of the small box girders and the precast slabs form a plane; tongue-and-groove connecting grooves are formed in the connecting positions of the small box girders and the prefabricated plates, and the tongue-and-groove connecting grooves are matched with the prefabricated plates in shape The small box girders and the prefabricated slabs are longitudinally embedded in a zigzag structure; a bridge deck cast-in-place layer is laid or not laid on the tops of the small box girders and the prefabricated slabs. Compared with the prior art, the method has the advantages that the structure is clear, construction is convenient, the construction quality of the small box girder can be improved, and influences on electrified railways, roads or structures are reduced; zigzag structures are adopted for splicing, and longitudinal displacement of the small box girders and the prefabricated slabs is restrained; the prestress of the small box girder is divided into internal prestress and external prestress; the durability is better, the bridge maintenance workload is reduced, and then the times of application blocking and control of railway and road departments are reduced.
本发明公开了一种应用于小箱梁的装配式横向连接结构，包括两个及以上并排设置的小箱梁，相邻两个小箱梁之间设有倒置凸形预制板，小箱梁、预制板顶部形成平面；小箱梁与预制板连接处设有企口连接槽，企口连接槽形状与预制板匹配；小箱梁与预制板纵向采用锯齿形构造相嵌；小箱梁与预制板顶部为铺设桥面现浇层或不铺设桥面现浇层。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质量，减少对电气化铁路、公路或构筑物影响；采用锯齿形构造拼接，约束小箱梁与预制板纵向位移；小箱梁预应力分为体内预应力和体外预应力；耐久性更好，减少桥梁养护工作量进而减少铁路、道路部门申请封锁、管制次数。
