Prefabricated stair connecting structure and construction method
The invention discloses a prefabricated stair connecting structure and a construction method. Platform sections are arranged at the two ends of a prefabricated stair of the prefabricated stair connecting structure, and platform grooves are formed in the platform sections; the composite stair beam comprises a concave composite bottom beam and a cast-in-place connecting section, a bottom beam groove is formed in the top surface of the concave composite bottom beam, the cast-in-place connecting section is located in the platform groove and the bottom beam groove, and the concave composite bottom beam, the cast-in-place connecting section and the platform section of the prefabricated stair form the whole stair beam to play a supporting role; connection joints are excellent in comprehensive performance and good in safety and reliability, installation of prefabricated concrete stairs is facilitated, and the assembly level and efficiency of a building structure are improved; a cast-in-place structure is converted into a prefabricated part single body, and machining of a part factory is facilitated; t-shaped steel plate embedded parts can be adopted, so that the workload of concrete cast-in-place wet operation is reduced, and the connecting work difficulty is also reduced; and the T-shaped steel plate embedded part is more suitable for factory standardized production, and quality control of the prefabricated part is facilitated.
本发明公开了一种预制楼梯连接结构和施工方法，所述预制楼梯连接结构的预制楼梯两端设置平台段，平台段设置平台凹槽；叠合梯梁包括凹型叠合底梁和现浇连接段，凹型叠合底梁顶面设置底梁凹槽，现浇连接段位于平台凹槽和底梁凹槽内，凹型叠合底梁及现浇连接段与预制楼梯的平台段构成梯梁整体，发挥支撑功能；其连接节点综合性能优良，安全可靠性好，便于预制混凝土楼梯的安装，提高建筑结构的装配化水平和效率；将现浇结构转化为预制构件单体，便于构件厂加工；可以采用T型钢板预埋件，不仅减小了混凝土现浇湿作业工作量，还降低了连接工作难度；并且T型钢板预埋件更适合工厂标准化生产，有利于预制构件的质量管控。
