轻钢结构与重钢结构一样的吗？当然不一样，首先用字面上了解就不一样，一个“轻”一个“重”，其次，就是用途有所不一样，具体是怎么不一样的呢？下面小编就和大家简单介绍一下他们两者之间的区别之处。

　　Is light steel structure the same as heavy steel structure? Of course, they are different. First of all, when understood literally, they are different, one is "light" and the other is "heavy". Secondly, their purposes are different. How are they different? Below, the editor will briefly introduce the differences between the two.

　　1.轻钢结构适用范围

　　1. Scope of application of light steel structure

　　（1）主承重结构为单跨度或多跨度门型刚度帧;

　　(1) The main load-bearing structure is a single span or multi span portal stiffness frame;

　　（2）轻屋顶和轻外墙；

　　(2) Light roofs and light exterior walls;

　　（3）重量不大于20t的桥式起重机或1-a5（轻中级）工人等级桥式起重机或3t悬吊起重机；（这对单梁起重机没有限制，主要是因为单梁起重机的起重重量通常在5吨以内，使用进口电动葫芦可以达到10吨，例如LD型，因此在单梁起重机规格上没有限制）

　　(3) Bridge crane with a weight not exceeding 20t or 1-a5 (light and medium) worker grade bridge crane or 3t suspended crane; (There are no restrictions on single beam cranes, mainly because the lifting weight of single beam cranes is usually within 5 tons, and using imported electric hoists can reach up to 10 tons, such as LD type, so there are no restrictions on the specifications of single beam cranes.)

　　也就是说，轻质的屋顶覆盖物（包括20t的举重）和轻质的外墙（也可以有条件地用于砌体墙）

　　That is to say, lightweight roof coverings (including 20t lifting weights) and lightweight exterior walls (which can also be conditionally used for masonry walls)

　　不同外观的单层实心腹板框架结构抗震设防墙是轻型钢结构。这里的轻量主要是指使用轻质材料，主要部分是中厚（6-12mm厚）钢板的H形变截面构件。因此，当前的轻钢含义主要是指符合该规定的刚性框架结构。

　　The seismic fortification walls of single-layer solid web frame structures with different appearances are lightweight steel structures. The term 'lightweight' here mainly refers to the use of lightweight materials, mainly consisting of H-shaped cross-section components made of medium thick (6-12mm thick) steel plates. Therefore, the current meaning of light steel mainly refers to rigid frame structures that comply with this regulation.

　　除上述门的刚性框架结构外，根据主要受力构件的组成，以下结构形式也应属于轻钢结构。

　　In addition to the rigid frame structure of the aforementioned doors, the following structural forms should also belong to light steel structures based on the composition of the main load-bearing components.

　　（1）冷弯薄壁钢制成的结构；

　　(1) Structures made of cold-formed thin-walled steel;

　　（2）管，方管，矩形管组成的结构；

　　(2) A structure composed of tubes, square tubes, and rectangular tubes;

　　（3）以上组件的组合结构；

　　(3) The combination structure of the above components;

　　建设部（草案）正在讨论的“低层轻钢结构装配住宅技术要求”表明，低层钢结构装配房屋也被列入轻钢结构类别。

　　The "Technical Requirements for Low rise Light Steel Structure Assembled Residential Buildings" currently under discussion by the Ministry of Construction (draft) indicates that low rise steel structure assembled houses are also included in the category of light steel structures.

　　根据一些参考值：例如每平方米的钢材含量（上限为45至50 kg / m2），截面的主要成分（H形，矩形，圆形等），钢板的厚度（上限为12 mm） ，3吨以内的最大部件重量（对照），跨度最大（通常在36 m内），结构形式（例如龙门架或类似结构），12 m以内的高厂房檐（对照），结构（对照）在9 m宽度等范围内，这些数据在确定工厂是否属于轻钢时会有所帮助。

　　Based on some reference values, such as the steel content per square meter (up to 45 to 50 kg/m2), the main components of the cross-section (H-shaped, rectangular, circular, etc.), the thickness of the steel plate (up to 12 mm), the maximum component weight within 3 tons (comparison), the maximum span (usually within 36 m), the structural form (such as gantry or similar structures), the high factory eaves within 12 m (comparison), and the structure (comparison) within a width of 9 m, these data will be helpful in determining whether the factory belongs to light steel.

　　2.重钢结构

　　2. Heavy steel structure

　　在目前的国家标准（包括过去已废除的国家规范）和以前的技术文件中均不用于烧结，现在主要区分轻钢结构房屋，重钢结构，主要用于大型建筑工程，如如：发电厂，冶金，石化厂，大型机加工车间和装配车间等。

　　In current national standards (including those that have been abolished in the past) and previous technical documents, sintering is not used. It is now mainly distinguished between light steel structure houses and heavy steel structures, which are mainly used in large-scale construction projects such as power plants, metallurgy, petrochemical plants, large machining workshops, and assembly workshops.

　　实际上，重钢结构更适合被称为钢。因为普通钢结构的范围很广，所以它可以包含各种钢结构，无论载荷大小，甚至是轻质钢结构的许多内容，以及钢结构规范中的内容。

　　In fact, heavy steel structures are more suitable to be called steel. Because the scope of ordinary steel structures is very wide, it can include various steel structures, regardless of the load size, even many contents of lightweight steel structures, as well as contents in steel structure specifications.

　　3.重钢结构特点

　　3. Characteristics of Heavy Steel Structures

　　（1）起重机的起重机重量：大于或等于20吨，且大于两个；

　　(1) Crane weight: greater than or equal to 20 tons, and greater than two;

　　（2）每平方米钢材用量：大于50公斤/平方米；

　　(2) Steel consumption per square meter: greater than 50 kilograms per square meter;

　　（3）主要部件的钢板厚度大于12mm厚，且构件截面的截面大部分为型钢的复合结构。

　　(3) The steel plate thickness of the main components is greater than 12mm, and most of the cross-section of the components is a composite structure of steel sections.

　　（4）车间的屋檐高，结构大；

　　(4) The eaves of the workshop are high and the structure is large;

　　比如：4个体育馆和展览中心，跨度大，高层或高层钢结构都可以称为重钢结构，尽管这种结构钢的数量大，范围大，但体育馆的结构，展览中心类型空间结构较多，高层或高层钢结构的框架剪力墙（支撑系统）与轻钢结构之间有显着差异。所以，小编认为这类建筑应以其各自结构内的分型为佳。

　　For example, four sports halls and exhibition centers with large spans, high-rise or high-rise steel structures can be called heavy steel structures. Although this type of structural steel has a large quantity and range, there are many types of spatial structures in sports halls and exhibition centers. There are significant differences between the frame shear walls (support systems) of high-rise or high-rise steel structures and light steel structures. Therefore, the editor believes that this type of building should be classified according to their respective structures.
