AI Technical Summary

Technical Problem

Existing prefabricated steel structure connection nodes suffer from problems such as complex construction, low installation efficiency, poor connection reliability, insufficient fatigue resistance, and difficult maintenance, making it difficult to meet the needs of rapid construction in industrialized buildings.

Method used

The design employs a damped sliding connection between a slider and a groove, combined with locking and protective components. This damped sliding connection enables rapid positioning, while the elastic locking structure using springs and limit rods ensures stability. Screws provide double protection, and the protective plate and friction-reducing coating enhance overall protective performance.

Benefits of technology

It enables rapid installation of steel structure connection nodes, high stability and strong reliability, and can maintain connection stability under extreme working conditions, thereby improving assembly efficiency and structural strength and extending service life.

Abstract

This utility model relates to the field of steel structure connection technology, specifically a prefabricated modular steel structure connection node structure, including a steel frame. One end of the steel frame is provided with a sliding groove, and the other end is provided with a slider. The slider passes through the sliding groove and is slidably connected to it with damping. A locking component is provided on one side of the upper end of the sliding groove, and a limit plate is provided at the lower end. A protective component is provided on the upper side of the sliding groove. The locking component includes a mounting box, a spring, a limit rod, and a limit block. Both the mounting box and the limit block are provided with screw holes. The protective component includes a protective plate and fixing nails. This design further simplifies the installation steps, eliminates the need for additional complex tools, improves the overall assembly efficiency, and enhances the overall structural strength and reliability of the steel structure.
