In steel structure, light steel and heavy steel are different
Determination of the structure of steel and steel structure does not have a unified standard, many experienced designers or project managers are often not completely clear, but we can take some data into account and judge:
1, workshop crane lifting weight: greater than or equal to 25 tons, can be considered as the steel structure.
2 per square meter, the amount of steel: greater than or equal to 50KG/M2, is considered to be a steel structure.
3, the main component steel plate thickness: more than or equal to 10MM, light steel structure with less.
In addition, there are some reference values: if the cost per square meter, the maximum component weight, maximum span, structure, higher than those in the eaves, whether building steel or steel when the judge can provide empirical data, of course, now many buildings are light and heavy steel have.
But there is something we can say for sure is Chongqing: such as: Exhibition petrochemical facilities, power plant, large-span stadium, center, high-rise or super high-rise steel structure. In fact, the national standards and technical documents are not Chongqing said, as the difference between light steel structure, perhaps said the general steel structure "steel" is more appropriate. Because the scope of ordinary steel structure is very wide, can contain all kinds of steel structure, regardless of load size, including the many contents of light steel structure, the characteristics of light steel structure technical specification only aimed at the "light" and provides some more specific content, and the scope is limited in single portal frame. The "Regulations" technology of steel structure of light-weight buildings with gabled frames with light roof and wall light (also has the condition to use the masonry wall) single portal frame structure, the light here mainly refers to the enclosure is made of light material.
Thus, the light steel and heavy steel structure not in itself but in the severity of the enclosure material level, and in the design concept is the same.
