Connecting structure of fragmented prefabricated assembled bent cap and construction method of connecting structure
The invention relates to the field of bridge prefabrication and assembly, in particular to a connecting structure of a segmented prefabrication and assembly bent cap and a construction method of the connecting structure. When the bent cap is divided into two pieces to be prefabricated in the bridge direction and connected through the wet joint, the wet joint is arranged at the top of the bent cap and the end of the transverse bridge direction, and the prefabricated bent cap is connected into a whole to jointly bear the using load effect. The wet joint reserved steel bars are arranged on the outer surface side of the prefabricated cover beam body structure, a large number of grooves do not need to be formed in the prefabricated cover beam, and cover beam prefabrication and on-site wet joint construction are facilitated. If the mode of forming grooves in wet joints is adopted, the arrangement of prestressed steel beams and reinforcing steel bars in the length direction of the prefabricated cover beam will be affected, and meanwhile, due to the mode of forming the grooves, a large number of reinforcing steel bar holes are reserved, and the construction complexity is increased. Based on the assumption that grooves are prevented from being formed in the length direction of the cover beam, the wet joint is arranged on the surface side of the prefabricated cover beam structure body, steel bars and prestress arrangement of the prefabricated cover beam are not affected by the wet joint, the work efficiency is improved, and the construction quality is easy to guarantee.
本发明涉及桥梁预制拼装领域，具体地说是一种分片预制拼装盖梁的连接构造及其施工方法。当盖梁沿顺桥向分为两片预制、通过湿接缝连接时，湿接缝设在盖梁顶部、横桥向的端部，将预制盖梁连接为整体，共同承担使用荷载的作用。湿接缝预留钢筋布置在预制盖梁主体结构的外表面侧，预制盖梁无须大量开凹槽，方便盖梁预制及现场湿接缝施工。如采用湿接缝开凹槽的形式，将影响预制盖梁沿长度方向的预应力钢束和钢筋布置，同时，开凹槽形式的模板、大量的预留钢筋孔洞，增加了施工的复杂性。本发明基于避免沿盖梁长度方向布置凹槽的设想，将湿接缝设在预制盖梁结构主体的表面侧，预制盖梁的钢筋和预应力布置不受湿接缝影响，提高工效，施工质量容易保证。
