济南轻型钢结构的辨别方式有哪些?

济南轻型钢结构建筑体系是一种轻型全装配式钢结构建筑,主要由结构钢和功能材料如热轧轻型H型钢、轻型焊接型钢、高频焊接型钢、冷弯薄壁型钢、薄壁钢板、薄壁钢管等组成,辅以各种装饰连接材料,能够满足建筑的特定使用功能和特定空间要求。
Jinan light steel structure building system is a kind of light-weight fully assembled steel structure building. It is mainly composed of structural steel and functional materials, such as hot-rolled light-weight H-beam, light-weight welded steel section, high-frequency welding steel section, cold-formed thin-walled steel, thin-walled steel plate, thin-walled steel pipe, etc., supplemented by various decoration and connection materials, which can meet the specific use function and space requirements of the building.

轻钢结构主要有三种:轻钢门式刚架建筑钢结构、冷弯薄壁型钢结构和钢管结构。起初,轻钢结构主要用于荷载小、跨度短的建筑。自20世纪80年代以来,它被广泛应用于仓库、办公室、工厂、体育设施等。重型钢结构应为:大型石油化工厂设施、大型机械锻造厂、港口码头设施、大跨度体育馆、会展区域、高层或高层建筑。
There are three kinds of light steel structure: light steel portal frame building steel structure, cold-formed thin-walled steel structure and steel pipe structure. At first, light steel structure was mainly used for buildings with small load and short span. Since the 1980s, it has been widely used in warehouses, offices, factories, sports facilities and so on. Heavy steel structure should be: large petrochemical plant facilities, large mechanical forging plant, port facilities, large span gymnasium, exhibition area, high-rise or high-rise buildings.

轻钢和重钢没有明确的界限。采用轻钢结构设,考虑腹板屈曲后的强度,可以减少加劲肋的设置,减少用钢量。这是轻钢结构。不然会用很多钢材,就是重型钢结构。但轻型钢结构一般只在起重机吨位小于20t时使用,大吨位起重机会采用重型钢结构,轻型钢结构的安全度不够。
There is no clear boundary between light steel and heavy steel. When using light steel structure design, considering the strength of web after buckling can reduce the setting of stiffeners and reduce the amount of steel. This is a light steel structure. Otherwise, a lot of steel will be used, that is, heavy steel structure. However, the light steel structure is only used when the crane tonnage is less than 20t, and the heavy steel structure is used for large tonnage crane, so the safety of light steel structure is not enough.
判断结构是重钢还是济南轻型钢结构,确实没有统一的标准,很多有经验的设计师或者项目经理往往不能完全解释清楚,但是我们可以用一些数据综合考虑判断:
It is true that there is no uniform standard for judging whether the structure is heavy steel or Jinan light steel structure. Many experienced designers or project managers can not fully explain it. However, we can use some data to comprehensively consider and judge:
1、车间起重机起重量:25吨以上,可考虑重型钢结构。
1. Lifting capacity of workshop crane: more than 25 tons, heavy steel structure can be considered.
2、每平方米用钢量:大于等于50KG/M2,可视为重型钢结构。
2. Steel consumption per square meter: more than or equal to 50kg / m2, it can be regarded as heavy steel structure.

3、主要部件钢板厚度:10毫米以上,少用轻钢结构。
3. Steel plate thickness of main parts: more than 10 mm, less light steel structure.
4、还有一些参考值,比如每平方米造价、大构件重量、大跨度、结构形式、檐高等。这些可以在判断厂房是重钢还是轻钢时提供经验数据。当然,现在很多建筑既有轻钢又有重钢。
4. There are also some reference values, such as the cost per square meter, the weight of large components, large span, structural form, eaves, etc. These can provide empirical data for judging whether the plant is heavy steel or light steel. Of course, many buildings now have both light and heavy steel.
可见,济南轻型钢结构和重型钢结构的区别不在于结构本身的重量,而在于围护材料的重量,结构设计的理念是一致的。
It can be seen that the difference between Jinan light steel structure and heavy steel structure lies not in the weight of the structure itself, but in the weight of the enclosure materials. The concept of structural design is the same.
