AI Technical Summary

Technical Problem

During the assembly and fabrication of existing steel structures, the use of pins and other limiting components may result in additional openings, affecting the strength of the steel components and the accuracy of the assembly. Furthermore, these limiting components are prone to sliding or bending, which can affect the stability and safety of the assembly.

Method used

The system employs quick-assembly components and a limiting mechanism, including a first connecting seat, a second connecting seat, a fixed seat, and a limiting mechanism. Through bolt connections and pin designs, it enables the rapid embedding and secure fixing of the secondary support steel, ensuring assembly accuracy and stability.

Benefits of technology

It simplifies the assembly process of steel structures, improves assembly efficiency, enhances the strength and stability of connections, prevents secondary support steel from falling off or shifting, and ensures the safety and stability of steel structures in use.

Abstract

This utility model relates to the field of support structures and discloses a quick-assembly steel structure, comprising: a main support steel, a secondary support steel, and a quick-assembly assembly. The top of the main support steel is fixedly connected to the quick-assembly assembly by a first bolt. A first connecting seat and a second connecting seat are fixedly connected to the outer walls of both sides of the quick-assembly assembly. The secondary support steel is embedded inside both the first and second connecting seats, and the first and second connecting seats are fixedly connected to the secondary support steel by a second bolt. Two sets of limiting mechanisms are fixedly installed on the top surface of both the first and second connecting seats. In this utility model, the design of the quick-assembly assembly achieves a quick and stable connection between the main support steel and the secondary support steel. Furthermore, the limiting mechanisms further enhance the stability of the secondary support steel, effectively preventing displacement or loosening under external forces, thereby ensuring the safety and reliability of the entire steel structure.
