Description

Technical Field

[0002] In the field of modern construction, with the enhancement of environmental awareness and the popularization of the concept of sustainable development, green and environmentally friendly buildings have gradually become an important development direction of the construction industry. As a green and environmentally friendly construction method, prefabricated steel structure frames are favored for their lightweight, high strength, recyclability and other characteristics. However, there are still some problems in the design and construction process of traditional prefabricated steel structure frames. Traditional prefabricated steel structure frames often use complex connection methods, such as welding and bolting, which are not only difficult to construct, but also time-consuming and labor-intensive, which is not conducive to improving construction efficiency. Although the prefabricated steel structure frame itself has good environmental protection, in the actual construction process, due to the complex connection method, a large amount of construction waste and noise pollution are often generated, causing certain damage to the environment. Traditional prefabricated steel structure frames are often relatively fixed in structural design and difficult to adapt to changing construction needs. Once the design is completed, it is difficult to change and adjust, which limits its application flexibility to a certain extent. Therefore, it is urgent to design a prefabricated steel structure frame for green and environmentally friendly buildings to solve the above problems. Summary of the invention
