[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."

[0003] With the continuous development of the domestic construction industry, prefabricated steel structure building systems are playing an increasingly important role in the industry. The construction process of prefabricated steel structure building systems is mainly divided into two parts: one is the integrated processing of steel structures in the factory; the other is the on-site assembly and installation of steel structures. Bolt connection is one of the installation techniques for on-site assembly and installation of steel structures. After aligning the holes of the two main steel structures to be assembled, the workers insert bolts into the pre-drilled holes on one side of the main steel structure and then turn to the other side to screw the nuts into the bolts for connection and installation. However, during the on-site assembly and installation of steel structures, workers usually work at heights where there are few points of leverage. Therefore, the traditional bolt connection installation technique presents significant difficulties and risks in high-altitude construction where there are already few points of leverage.

This structure simplifies and facilitates bolt installation and removal during on-site assembly of steel structures, thereby improving construction efficiency, shortening the construction cycle, and reducing safety risks.

The on-site installation process saves the step of fixing the nuts to the holes of the fixing bolts, improves construction efficiency, and shortens the construction cycle. Moreover, the workers on site do not need to work on both sides of the steel structure at the same time when working at height, which greatly reduces the safety risks for the workers. When this utility model is used for temporary projects, it avoids the loss of a large number of fixing nuts during the turnover process, greatly improves the turnover rate, saves costs, and promotes green construction.

[0047] In summary, the fixed nut structure of this utility model, which eliminates the need for on-site installation of steel structures, simplifies and facilitates the installation and removal of bolts during the on-site assembly and installation of steel structures, thereby improving construction efficiency, shortening the construction cycle, reducing safety risks, and is ingeniously designed, simple in structure, easy to manufacture, and low in manufacturing cost, making it suitable for large-scale promotion and application.
