Description

Technical Field

[0001] This utility model relates to the field of structural column reinforcement connection technology, specifically to a device for connecting structural columns of prefabricated steel structure buildings. Background Technology

[0002] In the field of construction engineering, prefabricated steel structure buildings are widely used due to their advantages such as fast construction speed and easy quality control. However, traditional welding methods for connecting steel reinforcement in structural columns suffer from low construction efficiency and difficulty in guaranteeing quality. Current technical solutions typically employ on-site welding for structural column reinforcement connections. This method requires specialized welding equipment and technicians, and the welding quality is significantly affected by human factors. The welding process is time-consuming, leading to low overall construction efficiency. Differences in the skill levels of different welders can result in inconsistent connection quality. Welding generates fumes and harmful gases, polluting the environment and posing a threat to the health of construction workers. Unstable welding quality can lead to structural safety hazards, especially during natural disasters such as earthquakes, where welded joints may become weak points in the structure. These are all problematic approaches. Utility Model Content
