众所周知，建筑物的质量取决于所用的建筑材料。如今，世界越来越重视环境保护，因此，国家提倡钢结构，楼承板，钢筋桁架楼承板等新型建材。从购物中 心和体育场馆等高层建筑到我们的个人住房建筑，也使用钢结构，楼承板等新型建筑材料。如果材料质量较差，则可能会对建筑产生重大影响。那么我们该如何选择楼承板型号及厚度呢?

As we all know, the quality of a building depends on the building materials used. Nowadays, the world pays more and more attention to environmental protection. Therefore, the country advocates new building materials such as steel structure, floor bearing plate, steel truss floor bearing plate. From high-rise buildings such as shopping malls and stadiums to our personal housing buildings, we also use new building materials such as steel structures and floor bearing plates. If the material quality is poor, it may have a significant impact on the building. So how do we choose the type and thickness of floor bearing plate?

楼承板主要分为开口式楼承板，燕尾式楼承板，闭口式楼承板，其中开口式楼承板经济实惠，闭口式楼承板性价比高。另外不管是那种型号的楼承板，利用率越高，成本就越便宜，利用率=有效宽度/原材料进料宽度。

Floor bearing plate is mainly divided into open floor bearing plate, swallow tail floor bearing plate and closed floor bearing plate. The open floor bearing plate is economical and the closed floor bearing plate is cost-effective. In addition, no matter what type of floor bearing plate, the higher the utilization rate, the cheaper the cost. The utilization rate = effective width / raw material feeding width.

但从美观的角度来说，闭口式楼承板，施工完毕后该板型板底平整、腹板贴合，大约3-5mm的间隙，如果不做吊顶，可以直接喷漆可做成企口型天花板（状似铝扣板）、也可披刮腻子后涂刷水性涂料做成平板天花板、还可直接贴壁布或壁纸装饰成彩色天花板；如果做吊顶的话，不用打孔，不用膨胀螺丝固定，直接用两片专用挂件挂在3-5mm的腹板贴合处，直接固定就可以。燕尾式楼承板就比较次之。以上就是各种板型的优点，看业主或工程要求，会从美观的角度还是经济的角度上来考虑板型的选择。

But from the aesthetic point of view, the closed-end floor bearing plate is perfect. After the construction, the bottom of the plate is flat, the web fits, and there is a gap of about 3-5mm. If the ceiling is not made, it can be directly painted into the tongue and groove type ceiling (like aluminum gusset plate), or painted with water-based paint after putty to make the flat ceiling, or directly pasted with wall cloth or wallpaper to decorate the color ceiling; If you do the ceiling, you don't need to punch holes or fix it with expansion screws. You can directly fix it with two pieces of special hangers hanging on the 3-5mm web joint. Swallow tail floor bearing plate is the second. The above are the advantages of various types of plates. According to the requirements of the owner or the project, the selection of plate type will be considered from the perspective of aesthetics or economy.

楼承板的厚度选择，主要是看楼板的厚度和钢结构次梁的间距，这个计算有技术含量的，他是根据楼承板的截面模量，截面惯性矩等有关计算出来。一般情况下，楼板厚底会在120mm左右，我们会建议客户选用肋高较高的。

The selection of the thickness of the floor bearing plate mainly depends on the thickness of the floor slab and the spacing of the secondary beams of the steel structure. This calculation has technical content. It is calculated according to the section modulus and section moment of inertia of the floor bearing plate. Generally, the thickness of the floor slab is about 120mm, so we suggest that customers choose the one with higher rib height.

在荷载方面，一般我们按照施工中应力计算依照规范，均布荷载为1.5KN/㎡,集中荷载2.2KN/㎡考虑。当然这需要客户给予提供，一般设计图纸中会有说明。有的项目通常会有设备层或者荷载比较大的楼层，这些楼层板厚会比较厚，施工荷载和后期荷载都会比较大。我们通常建议客户先用较厚的压型钢板。

In terms of load, we generally calculate according to the stress in construction, and according to the specification, the uniform load is 1.5kn/m2, and the concentrated load is 2.2kn/m2. Of course, this needs to be provided by the customer, which will be explained in the general design drawings. Some projects usually have equipment floors or floors with large loads. The slab thickness of these floors will be relatively thick, and the construction load and later load will be relatively large. We usually suggest that customers use thicker profiled steel sheet first.
