Prefabricated bridge deck slab wet joint connecting structure, prefabricated bridge and method
The invention discloses a prefabricated bridge deck wet joint connecting structure, a prefabricated bridge and a method thereof. The technical proposal is as follows: prefabricating concrete bridge deck, a plurality of conical tooth grooves are formed in one side of the prefabricated concrete bridge deck and there is an annular connecting joint steel bar extending out from the end face of the prefabricated concrete bridge deck; the annular connecting joint steel bars between the two prefabricated concrete bridge decks are overlapped and staggered; transverse penetrating steel bars are arrangedon the inner sides and the outer sides of the annular connecting joint steel bars; concrete is filled between the oppositely-arranged conical tooth grooves to form a wet joint. The conical tooth grooves are formed in the connecting interface of the prefabricated concrete bridge deck slabs, the bridge deck slabs are connected through the annular steel bars. The invention has the advantages of simple structure, reasonable stress, reliable force transmission, capable of meeting various requirements of the concrete bridge deck slabs in the normal use and bearing capacity limit state; The on-sitepouring amount is small, and construction is convenient and fast.
本发明公开了一种预制桥面板湿接缝连接构造、预制桥梁及方法，其技术方案为：包括预制混凝土桥面板，预制混凝土桥面板一侧设置若干锥型齿槽，相邻锥型齿槽之间具有伸出预制混凝土桥面板端面的环形连接接头钢筋；两个预制混凝土桥面板之间的环形连接接头钢筋搭接且交错布置；环形连接接头钢筋的内侧和外侧设有横向贯穿钢筋；相对设置的锥型齿槽之间填筑混凝土以形成湿接缝。本发明在预制混凝土桥面板连接界面开设锥型齿槽并通过环形钢筋在桥面板之间实现连接，其构造简单、受力合理且传力可靠，能满足混凝土桥面板正常使用与承载能力极限状态下的各类要求；其现场浇筑量小，施工方便快捷。
