Vertical Formwork Anchor With Rotational Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical formwork systems lack an efficient and user-friendly method for adjusting wall thickness, as they require complex mechanisms and multiple steps for axial positioning and rotation of tie rods, which complicates the construction process.
Innovation Solution
The anchor assembly features a front anchor element with a housing containing grooved faces and a planar face, allowing the tie rod to move axially in a fitting position and be fixed in a grooved position, combined with a blocking mechanism to prevent rotation, enabling easy wall thickness adjustment through three simple movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex mechanisms and multiple steps are used for axial positioning and rotation of tie rods, then positioning precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The fitting part is divided into distinct functional surfaces: a grooved face for engagement and a planar face for free movement. This segmentation allows the tie rod to be positioned and secured through simple rotational movements rather than complex mechanisms, achieving precise positioning while maintaining device simplicity
Solution Approach 2:
The system transitions between two dynamic states: when the grooved faces engage, axial movement is constrained; when the planar face contacts the grooved face, free axial movement is enabled. This dynamic behavior provides precise positioning control without requiring complex mechanical devices
2Manufacturing precision
If complex mechanisms and multiple steps are used for axial positioning and rotation of tie rods, then positioning precision is improved, but ease of operation deteriorates
Solution Approach 1:
The operator simply rotates the tie rod to switch between two states: engagement of grooved faces for secure positioning and contact of planar faces for free movement. This dynamic switching mechanism achieves precise positioning with minimal operational complexity, eliminating the need for multiple steps or complex procedures
Solution Approach 2:
By segmenting the fitting part into distinct grooved and planar faces, the system enables intuitive operator control through simple rotation, where the geometry itself guides the positioning process without requiring complex operational procedures
3Adaptability or versatility
If the tie rod is fixed in multiple axial positions, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The fitting part's grooved face can engage with the tie rod at multiple axial positions, allowing a single anchor assembly to accommodate various wall thicknesses. This multi-functional design provides adaptability without requiring complex adjustment mechanisms or multiple specialized components

AI summary
Anchor assembly for a vertical formwork that according to one embodiment includes a front anchor element and a tie rod having a first end that is housed in the front anchor element. The front anchor element and the first end of the tie rod are configured for fixing the front anchor element in different axial positions of the first end of the tie rod, such that when the tie rod is arranged in a fitting angular position it can move axially with respect to the front anchor, and when the tie rod is arranged in a fixing angular position the tie rod cannot move axially with respect to the front anchor. According to some embodiments the front anchor element also includes blocking means configured for blocking the rotation of the tie rod when it is arranged in the fixing angular position.
