Rotatable Anchor Counter Piece for Concrete Formwork
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing casing shell elements for concrete construction lack versatility in anchor attachment options, limiting flexibility in anchoring configurations and requiring separate components for different anchoring needs.
Innovation Solution
A casing shell element with a movable attachment device featuring multiple attachment facilities, including internal threads and pass-through holes, allowing for disengageable and tension-proof connections with anchors, enabling flexible anchoring options such as unilateral or two-sided anchoring and accommodating different anchor types without additional components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed attachment device is used in the casing shell element, then the structure is simple and stable, but the versatility in anchor attachment options is limited
Solution Approach 1:
The attachment device is designed to be movable relative to the casing shell, allowing it to be positioned at different locations along the casing shell length. This dynamic positioning capability enables the same attachment device to serve multiple anchoring configurations (unilateral, bilateral, different anchor types) without requiring multiple fixed attachment devices, thus improving versatility while controlling complexity.
Solution Approach 2:
The attachment device incorporates multiple attachment facilities (internal threads, pass-through holes) that can accommodate different anchor types and configurations. This multi-functional design allows a single attachment device to perform various anchoring functions, eliminating the need for separate components for different anchoring needs and resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If multiple separate components are used for different anchoring configurations, then the versatility is improved, but the device complexity and space requirements increase
Solution Approach 1:
Multiple attachment facilities (internal threads, pass-through holes, different anchor receptacles) are integrated into a single attachment device structure. This consolidation allows the device to provide various anchoring configurations (unilateral, bilateral, different anchor types) without requiring multiple separate components, thereby reducing the overall space occupied while maintaining versatility.
Solution Approach 2:
The attachment device is designed as a universal component that can accommodate different anchor types and configurations through its multiple attachment facilities. This eliminates the need for separate specialized components for each anchoring scenario, reducing space requirements while improving adaptability.
3Ease of operation
If the attachment device is fixed in position, then the manufacturing and assembly are simpler, but the flexibility in anchor insertion and attachment is reduced
Solution Approach 1:
The attachment device incorporates movable elements that allow adjustment of the attachment facilities relative to the casing shell. This movability enables flexible anchor insertion from different directions and positions while maintaining a relatively simple overall structure that does not significantly complicate manufacturing and assembly processes.

AI summary
The invention relates to a casing shell element for casing concrete and proposes a rotatable anchor counter piece for anchoring wherein the anchor counter piece includes two pass through holes intersecting each other which are optionally alignable with an anchor hole in a casing shell of the casing shell element for inserting an anchor by rotating the anchor counter piece. A pass through hole includes an internal thread for threading in a non-illustrated anchor and another pass through hole is configured without a thread for inserting an anchor onto which a non illustrated anchor nut is threaded for attachment purposes.
