Angled Threaded Rod Coupling for Misaligned Seismic Restraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for using threaded rods in construction, particularly when supports and connection points are misaligned, require heating and bending, which is time-consuming, skill-intensive, and can compromise the integrity of the rod, and do not efficiently accommodate multiple connections or seismic restraints.
Innovation Solution
An angled coupling system that allows multiple threaded rods to be connected at fixed angles without the need for bending, using internally threaded receptacles rotated at specific angles and support brackets, made from high-strength materials like steel or composites, to adjust the position of threaded rods in misaligned situations and provide secure connections for seismic and storm surge restraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If threaded rod is heated and bent to connect misaligned supports and connection points, then the rod can be shaped to reach both points, but the process is time-consuming, skill-intensive, and compromises the integrity of the rod
Solution Approach 1:
The invention divides the single threaded rod into multiple straight segments connected by coupling devices. Each segment remains straight and unmodified, while the couplings provide the necessary angular adjustments to connect misaligned supports and connection points, eliminating the need for heating and bending operations.
Solution Approach 2:
The coupling device acts as an intermediary component between threaded rod segments. It features internally threaded receptacles at different angles that receive and connect the rod segments, allowing misaligned connections without modifying the rod itself through heating or bending.
2Adaptability or versatility
If threaded rod is heated and bent to connect misaligned supports, then the rod can reach both points, but the integrity of the rod is compromised
Solution Approach 1:
The threaded rod is segmented into multiple straight sections that are not subjected to thermal or mechanical deformation. Each segment maintains its full structural integrity, while the coupling devices provide the flexibility needed to accommodate misalignment between supports and connection points.
Solution Approach 2:
The coupling device serves as an intermediary that absorbs the misalignment between rod segments and supports. By providing angular adjustment capability at the connection points rather than deforming the rod itself, the rod's structural integrity and reliability are preserved.
3Reliability
If multiple threaded rods are used for seismic restraints, then secure multi-point connections are provided, but the complexity of alignment and installation increases
Solution Approach 1:
The coupling device is designed as a universal connector that can accommodate multiple rod segments at various angles. This multi-functional component simplifies the installation of seismic restraint systems by providing a standardized connection method that works for different alignment scenarios, reducing the overall system complexity despite multiple connection points.
Solution Approach 2:
The coupling device incorporates dynamic angular adjustment capability through its internally threaded receptacles positioned at different angles. This allows the system to adapt to various seismic restraint configurations without requiring complex pre-alignment procedures, making multi-point connections more straightforward to install.

AI summary
An angled coupling to receive multiple pieces of threaded rod in order to adjust the location of the threaded rod, that can also be used for seismic restraints and/or storm surge restraints. The angled coupling includes a first internally threaded coupler and a second internally threaded coupler connected to the first coupler and extending from the first coupler at a defined angle from an axis thereof. The angled coupling may include additional couplings extending from the first coupler at the defined angle that may be spaced apart around the axis of the first coupling. The first coupler may be a passthrough coupler to either have a threaded rod pass therethrough or to receive a first threaded rod in a first side and a second threaded rod in a second side. The angled coupling is made of a high strength material (e.g., steel, cast iron, composites, high strength plastics, combinations thereof).
