Formwork Anchor Locking Ring for Adjustable Wall Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork anchor systems for concrete wall formwork require significant construction effort and additional anti-rotation devices to securely hold anchor ends in various latching positions, complicating handling and adjustment for different wall thicknesses.
Innovation Solution
A device featuring a pivotable locking ring with spring force engagement and a sealing ring system that allows for secure axial retention of the anchor end within a support sleeve, enabling easy adjustment and misalignment compensation without the need for complex threaded nuts or additional anti-rotation devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a split threaded nut is used for axial adjustment, then the anchor end can be adjusted to different positions, but the design complexity increases due to the need for additional anti-rotation devices
Solution Approach 1:
The locking element is divided into a locking ring and a separate locking piece that can be independently positioned and locked, allowing axial adjustment without requiring complex anti-rotation mechanisms. The locking ring can rotate freely while the locking piece provides the necessary retention at specific positions.
Solution Approach 2:
Instead of preventing rotation of the entire anchor end with anti-rotation devices, the invention allows rotation of the locking ring while using a locking piece to engage with the anchor end at specific axial positions, inverting the approach from restricting rotation to permitting it with selective engagement.
2Reliability
If a locking element with spring force is used, then secure holding in locking positions is achieved, but the device complexity increases
Solution Approach 1:
The locking mechanism uses spring force to automatically engage the locking piece with the locking ribs of the anchor end, providing self-locking functionality without requiring additional actuators or complex control systems. The spring automatically maintains engagement pressure.
Solution Approach 2:
The locking ring and locking piece are combined into a single integrated locking element that performs both the locking and spring force application functions, reducing the number of separate components needed while maintaining secure holding capability.
3Manufacturing precision
If the anchor receptacle is fixed rigidly, then positioning precision is maintained, but the ability to compensate for misalignment is reduced
Solution Approach 1:
The anchor receptacle is designed with pivotable support on one side, allowing it to dynamically adjust its position to compensate for misalignments while maintaining secure anchoring. This dynamic capability enables adaptation to varying installation conditions.
Solution Approach 2:
Only one side of the anchor receptacle is pivotably supported while the other side maintains fixed positioning, creating local flexibility where needed while preserving overall positioning precision. This selective pivoting allows misalignment compensation without sacrificing accuracy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides secure and adjustable anchor support with reduced construction effort, ensuring a tight passage and effective sealing across various positions and wall thicknesses, while allowing for simple handling and compensation of misalignments.
Implementation Method 1
a locking element axially supported in the anchor receptacle, which engages in locking recesses of the anchor end and can be released from the locking recesses against a spring force for the anchor end
Implementation Method 2
the anchor receptacle, which forms a support sleeve, can be supported on the base of an insert pot forming the formwork-resistant support stop by means of a sealing ring that tightly encloses the anchor end

AI summary
A device for the detachable support of a formwork anchor (3) on a formwork element (1) of a concrete wall formwork is described, comprising an anchor receptacle (9) axially supported on a formwork-fixed support stop for an anchor end (7) and a locking element axially supported in the anchor receptacle (9), engaging in locking recesses (22) of the anchor end (7) and releasable from the locking recesses (22) against spring force for the anchor end (7) which is slidably guided within the anchor receptacle (9).To ensure simple design conditions, it is proposed that the locking element forms a locking ring (19) pivotably supported on one side of the armature receptacle (9), enclosing the armature end (7), which is provided with locking ribs (21) which, in a locking position of the locking ring (19) pivoted towards the support stop against the armature end (7), engage in annular locking recesses (22) of the armature end (7) and, in a released position of the locking ring (19) pivoted away from the armature end (7), release a passage for the armature end (7).
