Milled Anchor Rail Embedding for Flexible Post-Construction Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for embedding and fastening anchor rails in buildings are cumbersome and costly due to the need for precise placement during construction, which is often not feasible, leading to incorrect installations and subsequent complex and expensive adjustments.
Innovation Solution
A method involving milling a slot in the building structure with a predetermined length, width, and depth to securely embed the anchor rail, allowing for flexible placement and adjustment after construction, using a milling machine with a guide rail and filling gaps with suitable materials to ensure secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If anchor channels are cast into the building structure during construction, then a very good force bond and corresponding force transfer between the anchor channel and the building structure is achieved, but the correct positioning of the numerous anchor channels is problematic and subsequent adjustments are not possible
Solution Approach 1:
The invention separates the embedding process into two independent stages: first, anchor channels are embedded in slots after construction; second, attachments are connected to the anchor channels. This segmentation allows each stage to be optimized independently, solving the contradiction between achieving strong force bonds and maintaining positioning flexibility.
Solution Approach 2:
The building structure is first constructed without anchor channels, then slots are milled into the completed structure, and finally anchor channels are embedded in these slots. This preliminary action of constructing the structure first allows for precise positioning and adjustment before the final embedding step, resolving the positioning flexibility issue while maintaining strong force bonds in the final assembly.
2Reliability
If anchor channels are embedded in a first surface close to an edge to a second surface, then attachments can be securely held, but the building structure area of the edge may break due to high forces
Solution Approach 1:
A retaining bracket is introduced as an intermediary element between the anchor channel and the building structure edge. The retaining bracket absorbs and distributes the high forces, preventing them from concentrating at the vulnerable edge area. This mediator allows the anchor channel to be positioned close to the edge for secure attachment holding while protecting the edge from breaking.
3Ease of manufacture
If dowel connections are used to attach attachments to the structure, then attachments can be connected, but it is difficult to attach the respective dowels in such a way that the corresponding attachment is predetermined, correctly positioned, with the correct distance
Solution Approach 1:
The anchor channel serves multiple functions: it provides a standardized embedding structure, enables precise positioning through the slot mechanism, and allows flexible attachment connection. This universal anchor channel system replaces the need for precise dowel attachment and makes positioning predetermined and accurate, resolving the contradiction between ease of connection and positioning precision.
