Flush End Plate Anchor Rail for Concrete Edge Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor rails require additional fastening elements and protruding end plates that can reduce the load-carrying capacity and create installation challenges when integrated into concrete structures, particularly in areas like tunnel segments and ceiling panels.
Innovation Solution
An anchor rail design where the end plate is fixed flush to the base body without protruding, utilizing an anchoring element that extends into the concrete member, allowing direct installation on the edge of a concrete member without reducing load capacity, and enabling efficient fastening of fastening elements along the rail length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an end anchor with insert element and mounting plate is used, then the anchor rail can be secured to concrete members, but additional fastening elements are required and the structure becomes more complex
Solution Approach 1:
The end plate is integrated directly with the base body of the anchor rail, eliminating the need for separate insert elements and mounting plates. The anchoring element is embedded directly into the base body, merging multiple components into a unified structure that reduces complexity while maintaining anchoring reliability.
Solution Approach 2:
The unnecessary intermediate components (insert elements, separate mounting plates) are extracted from the system. The design uses only the essential elements: the base body with embedded anchoring element and the integrated end plate, simplifying the overall structure.
2Ease of operation
If the end plate protrudes beyond the base body, then the anchoring element can be supported, but the load-carrying capacity is reduced and installation becomes more difficult
Solution Approach 1:
Instead of having the end plate protrude outward to support the anchoring element, the design inverts the approach by embedding the anchoring element directly into the base body and having the end plate integrate flush with the base body surface, eliminating the protrusion issue while maintaining support functionality.
Solution Approach 2:
The end plate is designed with specific local properties: it integrates flush with the base body on the outer surface while the anchoring element is embedded within the base body structure, creating different functional zones that optimize both installation ease and load-carrying capacity.
3Stability of the object's composition
If additional fastening elements are used to secure the end plate, then the end plate can be fixed to the base body, but the device complexity increases and installation time is extended
Solution Approach 1:
The end plate and base body are designed as an integrated unit where the end plate is formed as one piece with the base body, eliminating the need for separate fastening elements. This merging of components provides inherent fixation stability while significantly reducing installation time.
Solution Approach 2:
The integrated design of the end plate and base body provides self-fixation through their unified structure, eliminating the need for additional fastening operations. The structure serves itself by being inherently stable without requiring external fastening elements.

AI summary
An anchor rail has a base body having a longitudinal groove that extends along a longitudinal center line of the anchor rail, and a rail back, fixed with an anchor, on the side opposite the longitudinal groove. The base body has a one front side perpendicular to the longitudinal center line and fixed with an end plate that protrudes beyond the rail back to the side of the base body facing away from the longitudinal groove and supports an anchoring element, which extends from the side of the end plate on which the base body is arranged. The end plate is flush to the front side and does not protrude into the base body. For a building structure with a concrete member, into which an anchor rail is cast, the longitudinal groove is on a first router side of the concrete member. The end plate runs along a second side of the concrete member and the anchoring element protrudes into the concrete member.
