Combination Hanger Bracket Integrating Duct Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial and industrial construction, existing duct hanging systems require separate steel reinforcement and hanger assemblies, leading to material waste, increased labor costs, and inefficient use of space, as they necessitate the installation of trapeze hangers and additional supporting steel members, which are not always necessary.
Innovation Solution
A hanger bracket made of galvanized sheet steel or other suitable materials that combines duct pressure reinforcement and hanging functions, allowing direct attachment to the duct or strut, eliminating the need for separate trapeze hangers and reducing material and labor costs by using the same support members for both reinforcement and hanging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate steel reinforcement and hanger assemblies are used, then duct structural integrity and hanging support are achieved, but material waste increases, labor costs increase, and ceiling space is reduced
Solution Approach 1:
The patent combines separate steel reinforcement members and hanger assemblies into a single integrated combination hanger and reinforcement bracket assembly. The bracket includes a reinforcement portion that provides structural reinforcement to the duct and a hanger portion that suspends the duct from the ceiling, eliminating the need for separate components and reducing material waste.
Solution Approach 2:
The combination hanger and reinforcement bracket assembly serves multiple functions simultaneously: it reinforces the duct structure to withstand internal pressure, provides hanging support from the ceiling, and reduces overall material requirements. This multi-functional design eliminates the need for separate reinforcement and hanger systems.
2Ease of operation
If separate trapeze hangers and supporting steel members are installed, then duct hanging support is provided, but labor costs and installation time increase
Solution Approach 1:
The patent integrates the hanger function and reinforcement function into a single pre-assembled bracket unit. This combination bracket is installed as one component rather than requiring separate installation of trapeze hangers and supporting steel members, significantly reducing installation time and labor costs.
3Strength
If multiple separate support members are used, then adequate structural support is provided, but ceiling space and storage requirements increase
Solution Approach 1:
The patent consolidates multiple separate support members into a single combination hanger and reinforcement bracket assembly. This integrated design provides adequate structural support while occupying less ceiling space and requiring less storage area during installation compared to multiple separate components.

AI summary
A hanger bracket for supporting duct having an extended plate portion configured to support a surface of a duct and configured to accommodate coupling of the hanger bracket to the bottom surface of the duct; a vertical back plate portion attached to the extended plate portion and configured to couple the hanger bracket to a side surface of the duct; a top plate portion attached to the vertical back plate portion and in parallel arrangement with the extended plate portion and configured to accommodate a hanger element passed at a side of the duct above the bottom surface of the duct in an offset hanger attachment; and at least one gusset portions attached to a back side of the vertical back plate portion and an underside of the top plate portion to provide structural support to the top plate portion.
