Around 2008, under the impetus of Beijing Olympic Games, a boom of steel structure buildings emerged in China, and the demand for steel structure increased significantly, with a large number of steel structure venues, airports, stations and high-rise buildings coming up one after another. Now, under the advocacy of carbon peak and carbon neutral policy, steel structure building is once again valued, and even regarded as "the best form of green building" by domestic experts.

The strength of steel is higher than traditional brick and concrete structures. Steel structure buildings are also much stronger than a traditional wood structures. So, it can build more structures higher than traditional building materials.

Steel structure is one of the more common forms of structures in modern construction projects. The application of steel structure engineering construction technology is becoming more and more widespread in China, and the many superiorities possessed by steel structure are also valued, and the application of steel structure engineering has increased as a result. In this paper, we analyze the construction technology requirements of steel structure engineering, so as to strengthen the technical application and management of steel structure engineering and ensure the safety and reliability of the whole steel structure engineering. 　　 　　The drawings are the basis for the construction of steel structure engineering, and the technical person in charge of the project should organize the relevant technical personnel to review and digest the drawings, the purpose of which is to make the construction unit and each participating unit familiar with the design drawings, understand the engineering characteristics and design intent, find out the technical problems that need to be solved, and develop solutions; secondly, in order to solve the problems in the drawings, reduce the errors in the drawings, and put the quality of the drawings The hidden problems are eliminated in the bud. At the same time, we should do a good job of technical delivery of steel structure, the combination of construction and design, the combination of steel structure lifting and civil construction, steel structure and concrete structure prefabrication. The following is a detailed introduction of the main points of the quality control of steel structure engineering.

The continuous development of the economy has led to the progress of society, and the construction industry has also continued to move forward. Buildings are more like works of art, and steel structures are generally favored by architects, and the production, type and quality of steel and steel at home and abroad have increased substantially, but there are still many shortcomings in the field construction technology as well as quality control. This paper mainly analyzes the advantages and disadvantages of steel structure engineering construction technology, and how to control the construction quality through the correct construction technology in the construction process.

At present, the state's support for small and medium-sized enterprises is still very strong, with various preferential policies. This has led people to devote themselves to entrepreneurship one after another. At the same time, many small and medium-sized enterprises have sprung up like mushrooms after rain. Careful friends have found out: Compared with traditional workshops, new three-dimensional steel layout workshops are being used more and more. Why abandon traditional workshops and use new steel layout workshops? What are the advantages of steel layout workshops?

When cutting and blanking, the size of the flange plate is different, resulting in the inconsistency of the size of the H-shaped steel and the corbel, and the upper and lower flange plates of the steel beam connected with the corbel are misaligned by about one plate thickness; there are deep cut marks on the cutting edge, There are obvious depressions on the edge of the board, or there are deep sawtooth marks, the cutting roughness exceeds the standard, the edge of the panel is not vertically cut, and the splicing of the wrong side exceeds the standard.
