Frangible Retaining Clip for Concrete Panel Edge Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edge protection systems for concrete flooring panels are time-consuming to install and lack flexibility, often resulting in damage at the interface between panels when heavy objects are moved, as they do not effectively absorb weight transfer.
Innovation Solution
A modular edge protection system featuring frangible retaining clips, steel bridging pins, and adjustable support feet that allow for efficient alignment and secure coupling of concrete panels, enabling quick installation and flexible adaptation to panel contraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing edge protection systems are used to protect concrete panel edges, then damage to panels is reduced, but installation time increases and flexibility decreases
Solution Approach 1:
The edge protection system is divided into separate modular components: first part, second part, and retaining clip. These segments can be manufactured independently and assembled quickly on-site, reducing installation time while maintaining protection effectiveness. The modular design allows each component to be optimized for its specific function.
Solution Approach 2:
The retaining clip is designed with pre-formed engagement features that allow the first and second parts to be quickly connected without complex assembly steps. The frangible nature of the clip allows for preliminary positioning followed by secure locking, streamlining the installation process.
2Reliability
If existing edge protection systems are used to protect concrete panel edges, then panel edges are shielded from damage, but installation flexibility is limited
Solution Approach 1:
The system's modular segmented design allows it to adapt to different panel configurations, joint types, and installation locations. Each module can be positioned and oriented as needed, providing flexibility in installation while maintaining consistent edge protection performance.
Solution Approach 2:
The frangible retaining clip provides dynamic characteristics by allowing controlled separation after concrete setting. This enables the system to adapt to panel movement and contraction during curing while maintaining rigid protection during the setting phase.
3Strength
If rigid connection between first and second parts is used, then structural strength is improved, but ability to accommodate panel contraction is reduced
Solution Approach 1:
The retaining clip transitions from a rigid connected state during concrete setting to a separable/frangible state after setting. This parameter change allows the system to provide strong structural connection when needed while accommodating panel contraction and movement afterward.
Solution Approach 2:
The frangible retaining clip introduces dynamic behavior to the otherwise rigid edge protection system. It maintains rigidity and strength during the critical setting phase, then allows controlled separation to accommodate subsequent panel contraction and thermal movement.
