C-Profile Rail Surface Anchoring for Edge Breakout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor rails embedded in concrete near edges are prone to breakout due to transverse forces, requiring pre-casting of additional anchors during concrete production, limiting flexibility and surface usability.
Innovation Solution
A C-profile rail anchor system with surface anchors that can be subsequently attached, featuring a tab design that protrudes from the rail and can be connected to the concrete surface or embedded within, allowing for flexible anchoring and preventing breakout without obstructing the concrete surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rod-shaped anchors are cast into concrete during manufacturing to prevent breakout, then anchoring strength against transverse forces is improved, but flexibility of installation and surface usability deteriorate
Solution Approach 1:
The anchoring system is divided into two independent parts: the C-profile rail that is cast into the concrete, and the surface anchor that can be attached separately. This segmentation allows the rail to be installed during concrete pouring while the surface anchor can be added later, providing flexibility without compromising anchoring strength.
Solution Approach 2:
The C-profile rail with its slot is prepared in advance and cast into the concrete during manufacturing. This preliminary action creates a ready-made mounting structure that can later receive surface anchors, enabling both early installation of the rail and flexible subsequent attachment of anchors as needed.
2Strength
If rod-shaped anchors are cast into concrete during manufacturing, then anchoring strength is improved, but ease of manufacture deteriorates
Solution Approach 1:
By separating the anchoring function into the pre-cast C-profile rail and the separately attachable surface anchor, the system simplifies the concrete pouring process. The rail alone is cast without complex anchor arrangements, making manufacture easier while still achieving strong anchoring when surface anchors are attached later.
3Adaptability or versatility
If surface anchors are designed to protrude from the C-profile rail, then flexibility of subsequent attachment is improved, but the concrete surface usability deteriorates due to obstruction
Solution Approach 1:
The surface anchor utilizes the third dimension by protruding vertically from the C-profile rail rather than extending horizontally across the concrete surface. This vertical positioning allows the anchor to provide flexible attachment capability while minimizing obstruction of the concrete surface area for other uses.
