Novel concrete composite floor slab with light steel exposed out of slab bottom
The invention discloses a novel concrete composite floor slab with light steel exposed out of the slab bottom, and belongs to the technical field of constructional engineering. The novel concrete composite floor slab comprises a concrete bottom plate and a post-cast concrete strip, wherein the concrete bottom plate is composed of a prefabricated concrete layer, reinforcing steel bars and the light steel, the reinforcing steel bars are exposed in the length direction of the floor slab, the light steel is arranged at the slab bottom and is used as a stress component, the light steel is partially exposed and cannot be removed, the concrete bottom plate is inversely prefabricated in a factory, forward hoisting is performed during construction, and then the post-cast concrete strip is poured. According to the novel concrete composite floor slab with the light steel exposed out of the slab bottom, the rigidity and strength of the composite slab are increased, and construction loads can be borne. The thickness and weight of the floor slab are reduced, the cracking degree of concrete is reduced, and good economic benefits and large engineering values are obtained.
本发明公布了一种板底外露轻钢的新型混凝土叠合楼板，属于建筑工程技术领域。包括混凝土底板和后浇混凝土带，其中混凝土底板由预制混凝土层、钢筋和轻钢组成。所述钢筋沿楼板长度方向出筋，所述轻钢置于板底作为受力构件，部分外露，不可拆卸。工厂倒置预制所述混凝土底板，施工时正向吊装，再浇筑后浇混凝土带。本发明公布的板底外露轻钢的新型混凝土叠合楼板，提高叠合板的刚度和强度，能承担施工荷载。减小楼板厚度和重量，减轻了混凝土的开裂程度，具有良好的经济效益和较大的工程价值。
