Prefabricated concrete slab UHPC wet joint structure, construction method and design method
The invention relates to the technical field of bridge engineering, in particular to a prefabricated concrete slab UHPC wet joint structure, a construction method and a design method.The prefabricated concrete slab UHPC wet joint structure comprises prefabricated NC plates on the two sides and a UHPC wet joint poured between the prefabricated NC plates; reinforcement cages are arranged in the prefabricated NC plates, longitudinal straight ribs in the two prefabricated NC plates extend into the UHPC wet joint area, are arranged in the length direction of the UHPC wet joint in a staggered mode and are fixedly bound with each other, the connection interface of the prefabricated NC plates is designed to be in a formwork-free mode, the mode that the straight ribs are in lap joint to form the reinforcement cages is adopted to achieve connection of the prefabricated plates, and the problem that the joint interface is prone to cracking is solved. The method has the advantages that the structure is simple, the durability is good, various requirements of the concrete slab in normal use and bearing capacity limit states can be met, a bottom template is not needed, the construction efficiency and the construction quality are improved, rapid construction is realized, and the stress distribution of the structure can be optimized and the performance of the whole structure can be improved by simulating and adjusting wet joint parameters.
本发明涉及桥梁工程技术领域，具体涉及一种预制混凝土板UHPC湿接缝构造、施工方法及设计方法，包括两侧的预制NC板和浇筑在预制NC板之间的UHPC湿接缝；预制NC板内设有钢筋笼，两个预制NC板内的纵向直筋延伸至UHPC湿接缝区域内，在UHPC湿接缝长度方向错位设置，且相互绑扎固定，在预制NC板连接界面设计成免支模形式，并采用直筋搭接成钢筋笼的形式实现预制板的连接，解决了接缝界面易开裂的问题，耐久性好，能满足混凝土板正常使用与承载能力极限状态下的各类要求，无需底部模板提高了施工效率和施工质量，实现快速化施工，该方法通过模拟和调整湿接缝参数，可以优化结构的受力分布，提高整体结构的性能。
