55世纪楼承板越来越多的应用场景，但是真  正能把这个楼承板厚度选择好的，不清楚的人还是很多的。今天我们来看看楼承板怎么选择厚度。

There are more and more application scenarios of floor support plate, but there are still many people who don't know the thickness of this floor support plate. Today, let's see how to choose the thickness of the floor bearing plate.

楼板支撑板的应用场景越来越多，但是还是有很多人不知道这种楼板支撑板的厚度。今天我们来看看如何选择楼板承重板的厚度。

There are more and more application scenarios of floor support plate, but many people still don't know the thickness of this kind of floor support plate. Today, let's take a look at how to select the thickness of the floor bearing plate.

楼板承重板主要用作模板，但也有封闭楼板承重板作为楼板的结构部分。因此，不同的客户在使用的时候会感到困惑。主要体现在:一，我不知道如何选择厚度;二，材料的选择。让我们先来介绍一下这两种地板承重板的特点和设计要求:

The floor bearing plate is mainly used as the formwork, but there are also closed floor bearing plates as the structural part of the floor. Therefore, different customers will be confused when using it. Mainly reflected in: first, I don't know how to choose the thickness; 2、 Selection of materials. Let's first introduce the characteristics and design requirements of these two kinds of floor bearing plates:

一、开敞楼板承重板。此楼板承重板主要用作模板。他的要求是在施工阶段不能生锈，在施工阶段不能倒塌变形。一般来说我们的镀锌量不低于80g，但是由于市场竞争，一些钢厂生产的产品只有40g，或者设计院在建筑设计中不要求镀锌内容。就这样，常见的镀锌卷被广泛应用于各种小型建筑中。我们也遇到过很多使用开 放式地板承重板的项目，这些项目对镀锌有一定的要求:例如南京绿地项目，yx51-226-678地板承重板需要镀锌120g。

1、 Open floor bearing plate. The bearing plate of this floor slab is mainly used as a formwork. His requirement is not to rust in the construction stage and not to collapse and deform in the construction stage. Generally speaking, our galvanizing quantity is not less than 80g, but due to market competition, the products produced by some steel mills are only 40g, or the design institute does not require galvanizing in architectural design. In this way, the common galvanized coil is widely used in various small buildings. We have also encountered many projects using open floor bearing plates, which have certain requirements for galvanizing: for example, Nanjing Greenland project, yx51-226-678 floor bearing plates need 120g galvanizing.

55世纪二、封闭楼板承重板。作为承载部分的地板，设计院在使用时会有材质要求和镀锌含量要求(Q345B材质，275g)。但事实上，我们的一些客户在选择的时候会降低材料的使用要求:比如书城体育馆的型材钢板选用的是厚度为0.8的Q345B材料，对锌含量没有要求。事实上，这与设计不符——但这就是现实。

2、 Closed floor bearing plate. As the bearing part of the floor, the design institute will have material requirements and galvanized content requirements (Q345B material, 275g). But in fact, some of our customers will reduce the material requirements when choosing: for example, the profile steel plate of Shucheng gymnasium adopts Q345B material with thickness of 0.8, and there is no requirement for zinc content. In fact, this is not in line with the design - but this is the reality.
