多层住宅冷弯薄壁型钢―混凝土组合结构框架体系研究

发布时间:2016-1-20 11:12:03 浏览次数:779

    通过对国内外住宅体系的分析比较,提出本文了多层住宅冷弯薄壁型钢-混凝土组合结构框架体系。该体系是以冷弯薄壁方钢管混凝土为柱、冷弯薄壁C型钢背靠背高频焊接组成工字型梁、压型钢板上现浇筑混凝土组成组合楼板并与梁一起构成组合梁作为承重构件,以轻质节能保温型墙体作为围护结构组成。


    冷弯薄壁型钢截面开展,成型方式灵活,是一种高效经济型材,但当承受压力过大时容易发生屈曲,适合用作受拉构件;混凝土价格便宜,受压性能好。将二者结合起来组成组合结构能够充分发挥两种材料各自的优越性,同时,由于钢管对核心混凝土的约束作用


Through the analysis and comparison of domestic and foreign residential system, this paper puts forward the structure system of cold bending thin-walled steel and concrete composite structure. The system is in cold-formed square steel tube concrete column, cold-formed thin-walled C steel back-to-back high-frequency welding component I-shaped beam, pressure plate current pouring concrete composed of composite slab and beam together constitute the composite beam is used as a bearing member, to light energy-saving insulation wall as retaining structure is composed.


Development of cold-formed steel section, flexible forming, is a kind of high efficient and economic profiles, but when subjected to pressure too large, prone to buckling, is suitable for use as a tension member; the concrete is lower in price, compression performance. The combination of the two components can give full play to the advantages of the two materials, at the same time, due to the steel tube to the core of the role of concrete
