冷弯薄壁型钢-混凝土组合楼盖作为一种新型楼盖结构形式,需要从受力性能和构造方式方面进行更多的研究和认识。针对冷弯薄壁型钢-混凝土组合楼盖的构造特点,从基本构件、紧固件、压型钢板与楼盖梁连接、楼盖梁腹板开孔、支座加劲件、梁与柱的安装、楼盖梁布置及支撑系统等方面,对其构造进行了详细阐述。最后,提出了冷弯薄壁型钢-混凝土组合楼盖的简化模型——T形组合梁的实用计算公式,以供工程设计参考和借鉴。 Cold-formed thin-walled steel-concrete composite floor as a new type of floor structure requires more research and understanding from the aspects of mechanical properties and structure. In view of the structural characteristics of the cold-formed thin-walled steel-concrete composite floor cover, the basic components, fasteners, the connection between the profiled steel plate and the floor beam, the opening of the web beam, the stiffener, the beam and the column , Floor beam layout and support system, etc., on its structure were described in detail. Finally, a simplified model of cold-formed thin-walled steel-concrete composite floor is put forward, which is a practical calculation formula of T-shaped composite beams for engineering design reference and reference.
