Fully-prefabricated bridge expansion device
The invention discloses a full-prefabricated assembly type bridge expansion device which is arranged between two beam ends or between a beam end and a bridge abutment and comprises an expansion device body, a connecting piece and a prefabricated concrete structure, a reserved notch is formed between the two beam ends or between the beam end and the bridge abutment, and the prefabricated concrete structure is connected with the reserved notch through a wet joint. The telescopic device body is detachably connected with the prefabricated concrete structure. The post-cast strip concrete of an existing telescopic device can be prefabricated in a factory, and a prefabricated concrete structure with transverse and vertical cantilever steel bars is formed. The telescopic device body, the connecting piece and the precast concrete structure form the whole fully-prefabricated component, the component can be constructed in a factory, and particularly, the precast concrete structure can be subjected to standardized maintenance. And the construction quality and precision are guaranteed, factory-like full-prefabricated assembly type intelligent building of the telescopic device is truly achieved, and follow-up maintenance and replacement of the telescopic device are facilitated.
本发明公开了一种全预制装配式桥梁伸缩装置，设置于两梁端之间或梁端与桥台之间：包括伸缩装置本体、连接件、预制混凝土结构，两梁端之间或梁端与桥台之间设有预留槽口，预制混凝土结构与预留槽口之间通过湿接缝连接。伸缩装置本体与预制混凝土结构之间是可拆卸式连接。本发明可对现有伸缩装置后浇带混凝土进行工厂预制，形成带有横、竖向悬挑钢筋的预制混凝土结构。伸缩装置本体、连接件以及预制混凝土结构组成了整个全预制构件，并且该构件可以在工厂内完成施工，尤其是可以对预制混凝土结构进行标准化养护。保证施工质量和精度，真正实现了对伸缩装置的工厂化全预制装配式智能建造，便于后续伸缩装置的维护保养及更换。
