Description

Technical Field

[0001] This utility model belongs to the field of duct installation technology, and in particular relates to a two-way duct installation bracket. Background Technology

[0002] A duct support is a device used to fix and support ducts. It mainly bears the weight of the duct, ensuring that the duct can maintain a stable position after installation, preventing sagging or deformation due to its own weight or external forces, and ensuring the normal operation of the duct system. In particular, rectangular ducts usually provide support and constraint in two directions (horizontal and vertical), limiting the displacement of the duct in the horizontal and vertical directions. During the operation of the duct system, it reduces duct swaying caused by airflow impact, vibration and other factors, and improves the stability and safety of the system.

[0003] When the bracket is used to fix and support the duct, the support rod is prone to deformation. Therefore, a two-way bracket for duct installation is needed. The support rod of the two-way bracket is reinforced by the hanger rod to prevent deformation of the support rod and improve the stability of the two-way bracket support. Utility Model Content
