2. Based on the dual bearing design concept, the overall bearing capacity of the composite floor slab can be effectively improved through the combined action of the steel structure and the internal integrated pouring concrete. On the one hand, the concrete has fine compressive capacity, and corrugated steel plate and outside steel sheet then have fine tensile strength, and the mutual action through corrugated steel plate and the outside steel sheet of welding laminating and intussuseption concrete has effectively promoted composite floor's bending resistance bearing capacity. On the other hand, because the corrugated steel plates are arranged in an orthogonal manner, the bonding effect between the corrugated steel plates and the filled concrete can be effectively improved, and the longitudinal horizontal shear strength of the composite floor slab is further effectively improved. Meanwhile, the orthogonal corrugated steel plates have strong in-plane rigidity in two directions, the deformation of the floor slab under the load action is small, the damage of concrete can be reduced, the buckling deformation of the outer steel plates towards the inner side can be restrained under the action of the concrete, and the two steel plates act together to further improve the overall bearing capacity of the floor slab. In addition, the bilateral steel plates can be used as concrete templates, a formwork supporting procedure is omitted, the construction period is shortened, and the lower steel plates can effectively prevent the concrete from falling off due to serious damage.
