Prefabricated bridge deck wet joint structure and construction method thereof
The invention relates to the technical field of bridge engineering, and discloses a prefabricated bridge deck slab wet joint structure and a construction method thereof.The wet joint structure comprises a plurality of prefabricated bridge deck slabs, joints are formed between the adjacent prefabricated bridge deck slabs at intervals, and a plurality of steel bar assemblies extending to the outer sides of the prefabricated bridge deck slabs are arranged on the sides, close to the joints, of the prefabricated bridge deck slabs on the two sides; each steel bar assembly comprises long splicing steel bars and short splicing steel bars which are distributed in the thickness direction of the prefabricated bridge deck slab, the long splicing steel bars on the two sides are in lap joint to form a main annular steel bar frame, and the short splicing steel bars on one side and the long splicing steel bars on the other side are in lap joint to form an auxiliary annular steel bar frame. The closed annular steel bar frame is formed after the long splicing steel bars and the short splicing steel bars are in lap joint, and the force transmission path is clear; welding is not needed on site, and the construction period is shortened; transverse penetrating steel bars do not need to be placed on site, the construction efficiency is improved, the overall performance is better, and the bearing capacity of the wet joint is improved.
本发明涉及桥梁工程技术领域，公开了预制桥面板湿接缝结构及其施工方法，其中湿接缝结构包括多块预制桥面板，相邻的预制桥面板之间间隔形成接缝，两侧的预制桥面板近接缝侧均设置有延伸至预制桥面板外侧的多个钢筋组件，钢筋组件均包括沿预制桥面板厚度方向分布的长拼接钢筋与短拼接钢筋，两侧的长拼接钢筋互相搭接形成主环状钢筋框架，一侧的短拼接钢筋与另一侧的长拼接钢筋互相搭接形成副环状钢筋框架。本发明长拼接钢筋与短拼接钢筋搭接完成后形成闭合环状钢筋框架，传力路径明确；现场无需焊接，缩短了施工周期；现场无需放置横向贯穿钢筋，提高了施工效率，且整体性能更好，提高了湿接缝的承载能力。
