Square steel pipe use--steel pipe for steel structure
In our bodies, the skeleton that supports us, such as the thigh bone, the calf bone, etc., is a tubular structure. In addition, there are many plants in nature, such as reeds and bamboos, and their rods are also tubular. From these phenomena we can see that the pipe is a good support material. Steel pipes are used as supporting materials in steel structures and have broad application prospects. †On September 13th, the director of the Expert Committee of the China Steel Structure Association used these metaphors to bring the role of the pipe in the steel structure.
Pipes have a good prospect for application in steel structures. At the same time, due to the unique characteristics of the round pipe and the rectangular steel pipe, each has the most reasonable range of use, and the use of square-shaped steel pipe as the building column is better than the circular pipe. For example, in the position of the corner, the square tube can be used to maximize the effective use of the building area. Therefore, square steel pipes are more promising in steel-structured houses and high-rise steel structures.
At present, in China's steel structure industry, there are more round steel pipes, more mature technology, and corresponding product standards and multiple application technical regulations. When using round steel pipes, important parts of some buildings generally require seamless steel pipes, but on the one hand, because the seamless steel pipes are expensive, on the other hand, because the diameter of the welded pipes can be made larger, the pipe walls can also meet the design requirements. Most building components still use welded pipes. For example, a part of the grid structure uses straight seam welded pipes, and some use seamless steel pipes.
At present, there are fewer square-shaped steel pipe products produced in China, especially as pillars of high-rise or long-span buildings. The wall thickness still cannot meet the requirements for use. Even the square steel pipe produced by Baosteel Iron and Steel Technology Research Institute is 500mmx500mm, and the wall thickness is also It can only reach 19mm, so the terminal of Guangzhou New Baiyun Airport still uses imported billet tubes. China's building applications are still box-shaped beams. It is made of four thick plates welded, and the wall thickness requirements are also high. For example, the wall thickness is usually required to reach 20mm-60mm, or even 80mm, 100mm. The box beams and columns of the "Bird's Nest", the main venue of the 2008 Olympic Games, are generally 50mm, 60mm or 80mm, or even more than 100mm. If some can be replaced by square-shaped steel pipes, it will bring significant technical and economic effects. Some foreign manufacturers have been able to produce square-walled steel pipes with large wall thickness due to the special production process. Compared, it can greatly reduce the welding workload, and can also reduce the environmental pollution caused by welding. At the same time, the properties of steel such as rust resistance are more advantageous, and the surface is more beautiful.
The rectangular steel pipe provided by Shengzhou Yantai Steel Pipe Co., Ltd. is divided into two types: straight seam welded rectangular steel pipe and seamless rectangular steel pipe. The specifications are:
