摘　　要：通过检测鉴定工程案例,分析现浇楼盖配筋中存在如下两个问题:其一是空心楼盖受力钢筋的最小配筋面积问题;其二是无梁楼盖柱上、跨中板带配筋构造中上下层钢筋间拉结问题。在此基础上,提出了现浇混凝土空心楼盖与无梁楼盖的钢筋配置。文中阐述的观点、方法,应引起工程技术人员重视,并为其思考与运用提供借鉴。Two small problems existing in the reinforcement detailing of cast-in-situ floor are analyzed by testing and identifying the project cases:one is the minimum reinforcement area of the load-bearing reinforcement of the hollow floor.The other is the tie between the upper and lower steel bars in the upper and middle span slab and strip reinforcement structure of the beamless floor column.On this basis,the reinforcement detailing of cast-in-situ concrete hollow floor and beamless floor is proposed.The viewpoints and methods described in this paper should be paid attention to,considered and applied by engineering technicians,drawing inferences from other cases.
