眾所周知，建筑物的質量取決于所用的建筑材料。如今，世界越來越重視環境保護，因此，國家提倡鋼結構，樓承板，鋼筋桁架樓承板等新型建材。從購物中 心和體育場館等高層建筑到我們的個人住房建筑，也使用鋼結構，樓承板等新型建筑材料。如果材料質量較差，則可能會對建筑產生重大影響。那么我們該如何選擇樓承板型號及厚度呢?

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?

樓承板主要分為開口式樓承板，燕尾式樓承板，閉口式樓承板，其中開口式樓承板經濟實惠，閉口式樓承板性價比高。另外不管是那種型號的樓承板，利用率越高，成本就越便宜，利用率=有效寬度/原材料進料寬度。

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.

但從美觀的角度來說，閉口式樓承板，施工完畢后該板型板底平整、腹板貼合，大約3-5mm的間隙，如果不做吊頂，可以直接噴漆可做成企口型天花板（狀似鋁扣板）、也可披刮膩子后涂刷水性涂料做成平板天花板、還可直接貼壁布或壁紙裝飾成彩色天花板；如果做吊頂的話，不用打孔，不用膨脹螺絲固定，直接用兩片專用掛件掛在3-5mm的腹板貼合處，直接固定就可以。燕尾式樓承板就比較次之。以上就是各種板型的優點，看業主或工程要求，會從美觀的角度還是經濟的角度上來考慮板型的選擇。

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.

樓承板的厚度選擇，主要是看樓板的厚度和鋼結構次梁的間距，這個計算有技術含量的，他是根據樓承板的截面模量，截面慣性矩等有關計算出來。一般情況下，樓板厚底會在120mm左右，我們會建議客戶選用肋高較高的。

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.

在荷載方面，一般我們按照施工中應力計算依照規范，均布荷載為1.5KN/㎡,集中荷載2.2KN/㎡考慮。當然這需要客戶給予提供，一般設計圖紙中會有說明。有的項目通常會有設備層或者荷載比較大的樓層，這些樓層板厚會比較厚，施工荷載和后期荷載都會比較大。我們通常建議客戶先用較厚的壓型鋼板。

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.
