Prefabricated concrete primary and secondary beam rigid connection joint and support-free construction method
The invention belongs to the technical field of prefabricated house structural member connection, and relates to a prefabricated concrete primary and secondary beam rigid connection joint and a support-free construction method.A steel plate support is pre-buried in a prefabricated main beam, a double-angle steel bracket is welded to the support, and the steel plate support is combined with the tongue-and-groove design of a prefabricated secondary beam; and rigid connection and support-free installation construction of load-bearing steel bars of the primary and secondary beams are realized. The design meets the principle of equivalent cast-in-place, the rigidity of each stage of the prefabricated main beam is ensured, and support-free construction of a large-span floor system is supported. The double-angle steel bracket does not need additional protection after concrete pouring in the node area, and the cost is reduced. The matched detachable mold and the prefabricated part can be installed together, and efficiency and economical efficiency are improved. Multiple advantages of structural safety, construction convenience, economical efficiency, environmental protection and the like are integrated, an innovative and practical primary and secondary beam rigid connection and support-free construction scheme is provided for the fabricated concrete structure, and the technical progress and sustainable development of the building industry are promoted.
本发明属于装配式房屋结构构件连接技术领域，涉及一种预制混凝土主次梁刚接连接节点及免支撑施工方法，通过在预制主梁内预埋钢板支座，并在支座上焊接双角钢牛腿，与预制次梁的企口设计相结合，实现主次梁受力钢筋的刚性连接和免支撑安装施工。此设计满足了“等同现浇”原则，确保了预制主梁各阶段的刚度，支持大跨度楼盖免支撑施工。双角钢牛腿在节点区混凝土浇筑后无需额外防护，降低了成本。配套的可拆卸模具可与预制构件一并安装，提升效率与经济性。本发明综合了结构安全性、施工便捷性、经济性与绿色环保等多重优势，为装配式混凝土结构提供了一种创新且实用的主次梁刚性连接和免支撑施工方案，有助于推动建筑行业的技术进步与可持续发展。
