Rail Anchor Rivet Nuts Crimped Fixation Corrosion Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor rails face issues with high transport costs due to unfavorable volume and logistical efforts for different types of loads, and they often compromise corrosion protection during the welding process or securing connecting parts, which are expensive and ineffective.
Innovation Solution
The use of rivet nuts with a base body and a collar section as connecting parts, where the collar is crimped to widen and securely fix the rivets to the rail body, providing adequate corrosion protection and allowing for easy adaptation to different loads without significant increases in transport volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding process is used to fix anchor elements to rail body, then anchor elements are securely fixed, but anti-corrosion layer is destroyed and material properties are adversely affected
Solution Approach 1:
The invention extracts the harmful welding process from the fixation method and replaces it with mechanical connection using connecting parts with threaded connections. This eliminates the destruction of the anti-corrosion layer while maintaining secure fixation of anchor elements to the rail body.
Solution Approach 2:
The invention introduces connecting parts as an intermediary element between the anchor elements and the rail body. These connecting parts feature threaded connections that provide secure fixation without requiring welding, thus preserving the anti-corrosion layer and material properties of the rail body.
2Adaptability or versatility
If different types of anchor rails are made for different types of loads, then load-specific requirements are met, but logistical effort increases significantly
Solution Approach 1:
The invention creates a universal rail body design that can accommodate different types of loads through standardized receiving spaces and assembly openings. The same rail body can be used with different anchor elements and connecting parts configurations, eliminating the need for multiple specialized rail types and reducing logistical complexity.
Solution Approach 2:
The invention segments the anchor rail system into modular components: a universal rail body, various anchor elements, and different connecting parts. This segmentation allows flexibility in configuring the system for different load requirements while maintaining a consistent base structure, thereby reducing the number of unique components needed.
3Strength
If connecting parts are secured on rail body by traditional methods, then fixation is achieved, but corrosion protection at perforation edges is lost and costs increase
Solution Approach 1:
The invention converts the potentially harmful exposed perforation edges into a beneficial configuration by designing the connecting parts to overlap these edges. The connecting parts act as protective elements that cover the vulnerable perforation edges, transforming the corrosion risk into an opportunity for enhanced protection while maintaining fixation strength.

AI summary
The rail has connecting parts (21) provided in punched holes (15) and for fixing anchor elements (26) on a rail body (12). The connecting parts are formed as rivets with fixing sections plugged in the punched holes. The fixing sections are flanged for fixing the rivets on the rail body. The connecting parts have a fixing unit that fixes the anchor elements on the rail body. The rail body forms a receiver chamber (13) for receiving a connecting part (7) for fixing a fastening element (6) to the rail.
