Light steel keel framework concrete composite floor slab bottom plate
The invention discloses a light steel keel framework concrete composite floor slab bottom plate. The light steel keel framework concrete composite floor slab bottom plate comprises a reinforced concrete bottom plate and a light steel keel framework; bottom plate construction reinforcing meshes are longitudinally and transversely arranged in the reinforced concrete bottom plate; the light steel keel framework is composed of a longitudinally arranged C-shaped light steel keel and a transversely arranged U-shaped light steel keel; a plurality of supporting clamps are arranged on the opening side of the C-shaped light steel keel at certain intervals; the C-shaped light steel keel and the U-shaped light steel keel of the light steel keel framework are formed by rolling galvanized or non-galvanized steel strips through a cold bending process, and the wall thickness ranges from 0.6mm to 2.5mm; and a square hole is formed in the intersection of the middle of a web of the C-shaped light steel keel and the U-shaped light steel keel, and three edges of the square hole are punched to be separated from the web. The light steel keel used by the composite floor slab bottom plate is simple in production process and low in manufacturing cost; the composite floor slab bottom plate is simple in structure, so that prefabricated production is simple; and the light steel keel framework is combined with the concrete bottom plate, integrity is good, the bending resistance is high, and the shear capacity of the composite face is high. Therefore, the light steel keel framework concrete composite floor slab bottom plate has good market application prospects.
本发明公开了一种轻钢龙骨骨架混凝土叠合楼板底板，包括钢筋混凝土底板和轻钢龙骨骨架；钢筋混凝土底板内纵横布置底板构造钢筋网；轻钢龙骨骨架由纵向布置的C型轻钢龙骨和横向布置的U型轻钢龙骨组成；C型轻钢龙骨开口侧按一定间距安置若干支撑卡；轻钢龙骨骨架的C型轻钢龙骨和U型轻钢龙骨是由镀锌或非镀锌钢带经冷弯工艺轧制而成，壁厚在0.6‑2.5mm范围内；C型轻钢龙骨的腹板中部与U型轻钢龙骨相交处开方孔，方孔的三边冲压与腹板分离。本发明的叠合楼板底板所用轻钢龙骨生产工艺简单使得造价低；叠合楼板底板构造简单使得预制生产简单；轻钢龙骨骨架与混凝土底板结合，整体性好，抗弯能力强，叠合面抗剪能力强。所以具有很好的市场应用前景。
