In recent years, steel structures have achieved technological breakthroughs in many aspects and have been applied, which is an innovative achievement of modern technology. Good results have been achieved in materials, design, construction, monitoring, maintenance and other aspects.
Materials: Ultra-high-strength steels such as Q690 and Q890 have been developed, which are widely used in marine engineering, such as marine cranes, marine liquid tanks, automobiles, containers, engineering machinery pump trucks, etc. Although it is still less used in construction, there are many successful cases. According to analysis, the use of ultra-high-strength steel bars and steel can greatly reduce the amount of steel used in the structure while meeting the requirements of earthquake resistance performance, and have better bearing capacity.
New connection technology
High-strength bolt connection: Now the traditional riveting method and ordinary bolt connection are basically replaced by high-strength bolt connection, because it has the advantages of simple construction, good force performance, removable, fatigue resistance and no loosening under dynamic load, which greatly improves safety performance and installation efficiency.
Automated welding: Steel structure processing is inseparable from welding. Robot welding and laser welding technology have greatly improved welding quality and efficiency, freed up a lot of manpower, and reduced manual errors.
3D printing technology
3D printing technology is used in the manufacture of steel structure components. The application of this technology can improve the accuracy of components, make the manufacture of many complex components easy, and reduce material waste and improve production efficiency.
Modular production technology
The invention of modular production technology has better improved production efficiency and quality control, and greatly shortened the construction period. It provides possibilities and guarantees for emergency construction.
AI intelligent technology
AI intelligent technology is combined with scientific and technological elements such as big data and steel structure production, which is of great help to steel structure design, production, marketing, etc. It can not only optimize the design, save steel, but also avoid some human errors. At the same time, suggestions will be given for company marketing and planning. At the same time, the intelligent application of various production robots, such as welding robots, assembly robots, painting robots, laser drilling, etc., for steel structure production, not only greatly improves production efficiency, but also improves production accuracy and product quality.
High-efficiency fire-retardant coatings and anti-corrosion technology
The fire-retardant and anti-corrosion technology of steel structures has been greatly improved. Advanced fire-retardant coatings have greatly improved the fire resistance of steel structures and extended the safety time in fires. Anti-corrosion coatings and cathodic protection technologies have significantly extended the service life of steel structures.
International cooperation and standardization
Strengthening international cooperation has accelerated technical exchanges and innovations among countries. Steel materials that meet European, American, Japanese, and national standards can be purchased. As long as the drawings are approved, all kinds of required steel materials can be purchased. It is very conducive to the import and export of steel structure buildings.
The innovative application and achievements of steel structures have enabled the rapid development and application of steel structure buildings, with more guaranteed quality and richer application areas. I believe that steel structure buildings will be one of the main types of the future construction industry.
