Construction method of high-altitude large-cantilever concrete beam and slab structure
The invention belongs to the field of building construction, and relates to a construction method of a high-altitude large-cantilever concrete beam and slab structure. The construction method involves a cast-in-place concrete large-cantilever structure beam and an assembled prefabricated concrete composite slab, and the cast-in-place height of the structure beam is reduced through reinforcement optimization; after the beam body concrete strength grade of the cast-in-place concrete large-cantilever structure beam reaches 100% or above of the design strength, a formwork supporting system for the cast-in-place cantilever structure beam is dismounted; the prefabricated concrete assembled composite slab is arranged by means of the cast-in-place concrete large-cantilever structure beam, and no supporting system is arranged on the lower portion of the prefabricated concrete assembled composite slab; and connecting steel bars of the composite slab and the structure beam are assembled, laminated layer concrete is poured, and finally the complete high-altitude large-cantilever concrete beam and slab structure is formed. According to the construction method of the high-altitude large-cantilever concrete beam and slab structure, the construction cost investment for mounting and dismounting a formwork is greatly saved, and the construction method has the advantages of low risk of high-altitude work, simple process, convenient operation, high construction speed, high quality standard, high construction mechanization degree and the like.
本发明属于建筑施工领域，一种高空大悬挑混凝土梁板结构施工方法，包括现浇混凝土大悬挑结构梁和装配预制混凝土叠合板，通过配筋优化，降低结构梁的现浇高度；待现浇混凝土大悬挑结构梁的梁身混凝土强度等级达到设计强度100%及以上后，拆除现浇悬挑结构梁模板支撑系统；依托现浇混凝土大悬挑结构梁来安装预制混凝土装配式叠合板，预制混凝土装配式叠合板下部不再设置任何支撑系统；装配叠合板与结构梁的连接钢筋，浇筑叠合层混凝土，最终形成完整的高空大悬挑混凝土梁板结构。本发明不仅大幅度节约了模板安装及拆除等施工成本费用投入，还具有高空作业危险性小、工艺简单、操作方便、施工速度快、质量标准高、施工机械化程度高等优点。
