Pivoting Trapeze Hanger for Threaded Rod Strut Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for adding or removing horizontal members from threaded rod assemblies in architectural settings are labor-intensive and costly, requiring the entire assembly to be removed and reinstalled, which is inefficient and time-consuming, especially when modifying strut systems supporting pipes and electrical cables.
Innovation Solution
A trapeze hanger system with pivotally interconnected planar hanger portions that can be easily installed and removed from threaded rods, using identical pin profiles for both fastening and hinge functions, allowing for quick and efficient suspension and support of strut members without the need to disassemble existing assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional methods are used to add or remove horizontal members from threaded rod assemblies, then the assembly can be modified, but the entire assembly must be removed and reinstalled which is labor-intensive and time-consuming
Solution Approach 1:
The hanger is divided into two separable halves that can be opened and closed around the threaded rod. This segmentation allows the hanger to be installed independently without removing the entire strut assembly, enabling modifications to specific sections while leaving other parts in place.
Solution Approach 2:
The hanger transitions from a static closed position (when secured) to a dynamic open state during installation and removal. The movable halves allow the hanger to be opened for installation onto the threaded rod and then closed to secure the strut, enabling quick modifications without full disassembly.
2Adaptability or versatility
If traditional methods are used to add or remove horizontal members, then modifications can be made, but the procedure requires expensive shutdowns and substantial labor costs
Solution Approach 1:
By segmenting the hanger into openable halves, the invention allows targeted modifications to specific strut members without requiring shutdown of the entire system. This selective accessibility improves productivity by limiting work to only the necessary sections.
Solution Approach 2:
The hanger halves are prepared in advance and can be quickly assembled around the threaded rod before securing. This preliminary preparation enables rapid installation and removal operations, reducing overall project time and improving productivity.
3Adaptability or versatility
If an intermediate pipe rack is installed above an existing one, then new pipe or cable routing is enabled, but the old strut members must be removed and reinstalled which takes many hours
Solution Approach 1:
The dynamic opening and closing of the hanger halves enables quick installation of intermediate racks. The hanger can be opened to accommodate the threaded rod, then closed and secured in place, allowing multiple hangers to be rapidly installed along the rod without repeated removal and reinstallation of other components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The trapeze hanger system significantly reduces installation and removal time, labor, and costs by enabling easy addition or removal of strut members without disrupting existing setups, allowing for quick modifications to strut rack systems supporting pipes and cables.
Implementation Method 1
The hanger portions are pivotally interconnected defining an open position for placement about the threaded rod and a closed position defining a threaded aperture for threadedly receiving the rod. The hanger portions in the closed position is rotatably movable along the rod for supporting engagement with the strut.

AI summary
An interlocking suspension support hanger for mounting strut members off of a vertical threaded rod includes a pair of support hanger having a rectangular support body with a pivoting pin hole and a fastening pin hole on the support body and a recess opening leading to a center thread configured to fit around the vertical threaded rod. Further, a process for utilizing the support hanger to suspend a strut rack assembly from the vertically threaded rod without passing the assembly over the ends of the rod or removing the existing strut rack is disclosed.
