Prefabricated and assembled protective wall connecting structure for bridge and construction method of prefabricated and assembled protective wall connecting structure
The invention provides a prefabricated and assembled protective wall connecting structure for a bridge and a construction method of the prefabricated and assembled protective wall connecting structure, and relates to the technical field of bridge construction. The structure comprises a beam body, a prefabricated protective wall, grouting materials and connecting plates. The beam body is prefabricated, pre-embedded steel bars extend out of the corresponding positions of the beam surface during prefabrication, a bedding mortar groove is reserved, reserved grooves and supporting columns are arranged on the lower part of the prefabricated protective wall, connecting steel bars are arranged in the reserved grooves, bedding mortar is laid in the bedding mortar groove of the beam body during construction, supporting pads are arranged at the positions, corresponding to the supporting columns, of the bedding mortar groove, the prefabricated protective wall is hoisted, the supporting columns aresupported on the supporting pads, the connecting steel bars are inserted into the middles of the pre-embedded steel bars, the connecting plates pre-embedded in the supporting columns penetrate into pre-embedded bolts pre-embedded in the beam body, nuts are screwed for connection, grouting materials are poured from the upper parts of grout inlet holes till the grouting materials flow out from grout outlet holes, and thus assembling of the prefabricated protective wall and the beam body is completed. The structure is high in construction speed, large in construction allowable error, low in costand beneficial to application and popularization, and the quality is easy to guarantee.
本发明提供桥梁用预制拼装式防护墙连接结构及施工方法，涉及桥梁建造技术领域。该结构包括梁体、预制防护墙、灌浆料和连接板，预制梁体，预制时在梁面相应位置伸出预埋钢筋，并预留坐浆槽，预制防护墙下方设有预留槽和支撑柱，预留槽内部设置有连接钢筋，施工时,在梁体的坐浆槽内铺设坐浆料，在坐浆槽与支撑柱相应位置设置支撑垫，吊装预制防护墙，将支撑柱支撑在支撑垫上，将连接钢筋插入到预埋钢筋中间，将预埋在支撑柱内的连接板穿入预埋在梁体的预埋螺栓上，施拧螺母进行连接，再从进浆孔上方灌注灌浆料，直至灌浆料从出浆孔流出，完成预制防护墙和梁体的拼装。该结构施工速度快、施工容许误差大，质量易于保证，成本低，有利于推广应用。
