轻型钢结构

Light steel structure

轻型钢结构就是只用使用主要受力构件的截面组成来进行区分的，我们常见的轻型钢结构有：

Light steel structures are distinguished only by using the section composition of main stressed members. Our common light steel structures are:

1、由焊接和高频焊接轻型钢组成的结构；

1. Structure composed of welded and high frequency welded light steel;

2、由圆管、方管、矩形管等做成的结构；

2. A structure made of round tubes, square tubes, rectangular tubes, etc;

3、由冷弯薄壁型钢做成的结构；

3. A structure made of cold-formed thin-walled steel sections;

4、由热轧轻型型钢做成的结构；

4. Structure made of hot rolled light section steel;

重型钢结构是没有一个统一的标砖的，基本常见的几种类型有：

There is no unified standard brick for heavy steel structure. The basic common types are:

1、每平米用钢量：大于等于50kg/m2，可以认为是重型钢结构；

1. Steel consumption per square meter: greater than or equal to 50kg / m2, which can be considered as heavy steel structure;

2、主要构件钢板厚度：大于等于10mm，轻型钢结构使用较少，一般都是重型钢结构；

2. Steel plate thickness of main components: greater than or equal to 10mm, light steel structure is rarely used, and generally heavy steel structure;

3、厂房行车起吊重量：大于等于25吨，可以认为是重型钢结构

3. The lifting weight of the crane in the plant: more than or equal to 25 tons, which can be considered as a heavy steel structure

轻型钢构造主要是用在不接受大载荷的承重修建。选用轻型H型钢，焊接或轧制，变截面或等截面，做成门形钢架支承。压型钢板或轻质夹芯板作屋面、墙面围护构造，选用高强螺栓、一般螺栓及自攻螺丝等连接件和密封资料拼装起来的低层和多层预制装配式钢构造房屋系统。轻钢构造住所构造悉数选用冷弯薄壁钢构件系统构成，钢骨选用超级防腐高强冷轧镀锌板制作，有用防止钢板在施工和使用过程中的锈蚀的影响，增加了轻钢构件的使用寿数。构造寿数可达一百年，很多的厂房都是由这样的钢结构材质制作而成。

Light steel structures are mainly used in load-bearing buildings that do not accept large loads. Light H-section steel is selected, welded or rolled, variable section or equal section, and made into portal steel frame support. Profiled steel plate or light sandwich panel is used as roof and wall enclosure structure, and low-rise and multi-storey prefabricated steel building system assembled with high-strength bolts, general bolts, self tapping screws and other connectors and sealing data. The light steel structure is composed of cold-formed thin-walled steel member system, and the steel frame is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which can effectively prevent the influence of corrosion of steel plate during construction and use, and increase the service life of light steel members. The structural life can reach 100 years. Many factories are made of such steel structure materials.
