Steel structure is a structure made of prefabricated materials (steel), processed into components by the factory, and then assembled on site. Therefore, the connection nodes between components are an important part of forming the steel structure and ensuring the safe and normal operation of the structure. So how many types of steel structures are there? Let's learn about it with Huaye Fire Protection.
How many types of steel structures are there?
⒈ Portal steel structure;
⒉ Frame steel structure-pure frame, central support frame, eccentric support frame, frame tube (dense column frame);
⒊ Grid structure-grid, grid shell;
⒋ Cable membrane structure-cable structure, membrane structure, among which membrane structure includes tensioned, skeleton and inflatable membrane structure.
Judgment of the difference between light steel structure and heavy steel structure:
1. The lifting weight of the factory crane: greater than or equal to 25 tons, it can be considered a heavy steel structure.
2.The amount of steel used per square meter: greater than or equal to 50KG/㎡, it can be considered a heavy steel structure.
3.Thickness of steel plate of main components: greater than or equal to 10MM, less used in light steel structure.
4.Judging whether it is heavy steel structure or light steel structure from the experience of commonly used data: cost per square meter, maximum component weight, maximum span, structural form, eaves height, etc.
5.The so-called light steel structure usually refers to the structure composed of the following steel materials: cold-bent thin-walled steel structure, hot-rolled light steel structure, welded or high-frequency welded light steel structure, light steel pipe structure, welded composite beams with thin plate walls and welded composite columns.
Steel structure is a green and low-carbon industry actively encouraged around the world, and is also the backbone of of construction industry transformation. Respect the trend of sustainable development, Honglu will continue to keep the largest high-quality steel structure,steel buildings manufacturing and R&D base in China with leading technology, optimal quality, and the most satisfactory customers, and become the most trustworthy and competitive supplier of steel structures and related supporting products.
