In the steel structure construction project, a lot of workshops, but in, uses the light steel structure to carry on the architectural design. In the design stage of light steel structure engineering, the smooth elements of processing and manufacturing, installation and construction stage should be considered. In the processing and installation stage, various design assumptions in the design stage should also be considered, and each link should be strictly approved. This requires proper and loose design and installation disclosure to prevent quality incidents.
The tensile and compressive strength of steel structure is absolutely high, the member section is small, the self weight is light, the structure function is good, the construction progress is fast, and the environmental purification is small. Practical places such as: steel structure industrial workshops, high-rise buildings, sports venues, steel residential buildings, bridges and various public buildings. In particular, with the establishment of Beijing Olympic venues and Shanghai World Expo venues, a large number of steel structure projects are widely used, which fully shows the characteristics and advantages of steel structures. Although a large number of steel structure engineering is widely used, many simple achievements and technical problems in the design, processing and construction of steel structure engineering have not been deeply understood and realized. Steel structure engineering, especially steel structure construction engineering, is a high-risk industry. Therefore, light steel structure requires high quality of designers, processing personnel and construction personnel. If there is a little carelessness, thoughtlessness and experience, there will be quality insurance incidents, and even all of them will fall down, forming a major obligation incident. The quality incidents of steel structure engineering can be divided into design cause incident, processing cause incident, installation cause incident and application cause incident according to their working stages. It can be divided into various elements, multiple elements and simple elements according to the elements forming the incident.
