Description

Technical Field

[0001] This invention relates to the field of supports and hangers, and more specifically to a self-tapping heavy-duty prefabricated support and hanger system. Background Technology

[0002] Currently, the most common connecting profiles and bolts used in the electromechanical installation industry for support and hanger products are standard, universal products, requiring pre-drilling or welding before assembly. Secondly, lightweight prefabricated support and hanger systems using cold-formed thin-walled C-channel steel are also common. This system has two common connection methods. The first is a mechanical connection of structural components using a locking toothed mesh; however, this mechanical meshing force is not stable enough, and the force value is relatively small, limiting its use to lightweight supports with smaller loads. The second is a lightweight system using through-bolt connections. While this method offers a significant improvement over mechanical meshing, the strength and stiffness of the profiles are relatively low, making it unsuitable for supporting large pipelines or power pipelines. Furthermore, hinged connections lack stability as supports. A third method uses through-bolt square steel systems, which have complex manufacturing processes, high component costs, and limited installation efficiency and form. Market acceptance is low. The drawbacks of these methods include the need for pre-drilling or welding, increasing cost and time; the installation position is usually not adjustable, resulting in low tolerance for errors; and the connection strength, stiffness, and stability may be limited, especially under uneven stress or high-temperature environments. Therefore, those skilled in the art have provided a self-tapping, heavy-duty prefabricated support system to solve the problems mentioned in the background art. Summary of the Invention
