Sliding Anchorage Assembly for Even Strut Channel Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchorage assemblies for overhead applications in strut channels lack efficient mechanisms for secure installation and even load distribution, leading to potential instability and safety concerns when used with self-retracting lifelines or other safety equipment.
Innovation Solution
The anchorage assembly comprises first and second plates that are slidably movable relative to each other, with an upper head and a spreader ramp on each plate, allowing for vertical movement and spreading apart to securely engage with strut channel holders, ensuring even load distribution and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the anchorage assembly uses a fixed rigid structure, then the installation is simple, but the load distribution is uneven and stability is poor
Solution Approach 1:
The anchorage assembly employs plates that are slidably movable relative to each other, transitioning from a static configuration to a dynamic one. The plates can spread apart vertically along the strut channel, allowing the structure to adapt to load conditions and achieve stable engagement with the channel walls, thereby improving stability while maintaining reasonable structural complexity.
Solution Approach 2:
The anchorage assembly is divided into multiple separate plates (first plate and second plate) that can move independently relative to each other. This segmentation allows each plate to engage separately with the strut channel holders, distributing the load more evenly and improving overall stability compared to a single rigid structure.
2Stress or pressure
If the anchorage assembly uses a single rigid plate, then the device complexity is low, but the load distribution across the strut channel is uneven
Solution Approach 1:
The slidable plates can adjust their vertical positions independently, allowing the anchorage assembly to distribute loads more evenly across the strut channel. When loaded, the plates spread apart, creating multiple contact points with the channel holders, which improves stress distribution compared to a single rigid plate.
Solution Approach 2:
By dividing the anchorage into multiple separate plates, the load is distributed across multiple contact points with the strut channel holders. Each plate can engage independently, creating a more uniform stress distribution pattern along the channel length.
3Reliability
If the plates are fixed in position, then the structure is simple, but the security and stability of attachment are reduced
Solution Approach 1:
The slidable plates provide a dynamic engagement mechanism that enhances security. When the anchorage assembly is installed, the plates can spread vertically and engage with the strut channel holders, creating a more secure attachment that adapts to the channel geometry and load conditions, thereby improving reliability.
Solution Approach 2:
The spreader ramps are positioned to prevent the plates from sliding downward prematurely. The ramps create a mechanical interference that stops the plates at predetermined positions, ensuring secure engagement with the channel holders before full load is applied, thus enhancing attachment security.
