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.

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?

Steel structure is widely used in large plants, stadiums, super high rise and other fields because of its light weight and easy construction, summarizing the requirements of steel structure for reference. 　　 　　A: steel structure installation requirements  　　(1) There should be a construction process or program, measurement correction, high strength bolt installation, negative zero construction and welding process should be tested or evaluated before installation.  　　(2) The detection of installation deviation should be carried out after the structure is formed as a spatial stiffness unit and connected and fixed. 　　(3) The installation must control the construction loads such as roof, wall platform, ice and snow loads, etc. are strictly prohibited to exceed the bearing capacity of beams, trusses, floor panels, roof panels, platform laying.

The main measures to improve the design of steel structures and the main points of installation technology

It is often heard that purlins, C-shaped steel, Z-shaped steel, and CZ-shaped steel are mentioned. In fact, they include C-shaped steel and Z-shaped steel, but both C-shaped steel and Z-shaped steel perform better than traditional steel products in practical applications.

There are no specific requirements for the service life of steel structures in the code, but in the structural design, according to the loaded code, the load statistical value of 50 years as the basic cycle is basically adopted, that is, the probability that the normal design steel structure will be damaged due to excessive load within 50 years is very small.

The installation of the steel structure needs to be hoisted first. Generally speaking, the middle is hoisted first, and then the outer side is hoisted. The principle of first going down and then up is adopted. Fix the middle part first and push through the ends. After being hoisted in place using tools, the anchor bolts are used to fasten them, and then the steel column bolts and pressure plates must be welded before the steel columns can be installed.
