The floor support plate does not require bolts to be designed according to the composite beam, but it must be constructed according to certain bolts to ensure the integrity of the plate and beam. The direction along the rib on the beam support, whether it is continuous or hinged, depends not on the profiled steel plate, but on the negative bending moment reinforcement. The compression of the profiled steel plate can be completely ignored, and the vertical rib direction is generally considered as hinged, but should be equipped with crack resistant structural reinforcement.

关于楼承板的配筋计算，一个是上部钢筋(包括负弯矩钢筋)的问题，一个是下部受力钢筋的问题。

Regarding the reinforcement calculation of the floor support plate, there are two issues: one is the upper reinforcement (including negative bending moment reinforcement), and the other is the lower load-bearing reinforcement.

上部钢筋，也叫分布钢筋温度钢筋，起的作用主要是抵抗四温度变化和混凝土收缩在垂直于板跨方向所产生的拉应力。通常钢筋直径不应小于6mm，间距不大于250mm。而压型钢板楼板的上部钢筋计算方法和普通混凝土楼板相同，按照此方式计算即可。

The upper reinforcement, also known as distributed reinforcement temperature reinforcement, mainly plays a role in resisting the tensile stress generated by temperature changes and concrete shrinkage in the direction perpendicular to the slab span. Usually, the diameter of the steel bars should not be less than 6mm and the spacing should not exceed 250mm. The calculation method for the upper reinforcement of the profiled steel plate floor slab is the same as that of the ordinary concrete floor slab, and can be calculated according to this method.

下部钢筋，主要是承受正弯矩，根据压型钢板的类型可以按照组合楼板和非组合楼板两个方面来考虑。无论是上部钢筋还是下部钢筋均需考虑楼板的保护层厚度，下部钢筋尤其不允许直接放置在压型钢板上面。

The lower steel bars mainly bear positive bending moments, and can be considered in two aspects: composite and non composite slabs based on the type of profiled steel plates. Both the upper and lower steel bars need to consider the thickness of the protective layer of the floor slab, and the lower steel bars are particularly not allowed to be placed directly on the profiled steel plate.

组合楼板截面配筋可采用以下几种形式：组合楼承板正弯矩区的压型钢板满足受弯承载力要求时，正弯矩区可不配置钢筋，可仅在负弯矩区配置受力钊筋及在楼板顶面配置温度抗裂钢筋；组合楼承板正弯矩区的压型钢板不能满足受弯承载力要求或耐火极限计算不能满足要求时，可在正弯矩区配置受力钢筋；当组合楼承板内承受较大拉应力时，可在楼承板板肋顶布置钢筋网片。

The reinforcement of composite floor sections can be in the following forms: when the profiled steel plate in the positive bending moment area of the composite floor bearing plate meets the requirements for bending bearing capacity, the positive bending moment area may not be equipped with reinforcement, and the load-bearing reinforcement can only be installed in the negative bending moment area and the temperature crack resistance reinforcement can be installed on the top surface of the floor; When the profiled steel plate in the positive bending moment area of the composite building support plate cannot meet the requirements for bending bearing capacity or the fire resistance limit calculation cannot meet the requirements, load-bearing steel bars can be configured in the positive bending moment area; When the composite floor support plate is subjected to significant tensile stress, steel mesh can be arranged at the top of the rib of the floor support plate.
