In recent years, with the construction technology mature of cast-in-place concrete hol ow floor, this technique is widely used. This article explains the current development sit-uation of floor technology, makes an analysis of the force cha-racteristics of floor structure, expounds the calculation method of floor structure and scope, and briefly introduces the design points, structure and construction key of cast-in-situ concrete hol ow floor.% 近年来,随着现浇混凝土空心楼盖技术的成熟,建筑工程广泛地运用了这个技术。本篇文章详细解释了楼盖技术的发展现状,分析了楼盖结构的受力特性,重点阐述了楼盖结构的计算方法及适应范围,并对现浇混凝土空心楼盖结构的设计要点、构造及施工重点等进行简述。
