Formwork Strut Anchoring Assembly for Ground-Level Diagonal Bracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems for formwork structures require operators to access high heights to secure anchoring bars, are limited to specific types of bars, and are not quick or robust enough for practical use.
Innovation Solution
A fastening assembly comprising a male element with perpendicular pins and a female element with a slot and protuberance, allowing for easy placement and secure fastening of anchoring bars without the need for elevated access, suitable for various bar types and profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wedge clamps or couplers are used to fasten anchoring bars between struts, then the anchoring system provides diagonal support to prevent formwork collapse, but the operator must access high heights to install them, creating safety risks and time loss
Solution Approach 1:
Instead of fastening the anchoring bar to the upper end of the strut (which requires high access), the invention inverts the fastening location to the lower end of the strut. The L-shaped fastening element engages with the anchoring bar horizontally at ground level, eliminating the need for operators to access elevated positions while maintaining anchoring reliability.
2Ease of manufacture
If wedge clamps are used for fastening, then the anchoring system can be assembled, but it is limited to wood or partially deformable bars due to friction-based fastening, reducing versatility
Solution Approach 1:
The invention replaces the friction-based wedge mechanism with a mechanical interlocking system. The L-shaped fastening element creates a physical key-lock engagement with the anchoring bar and strut, where the horizontal portion engages the bar and the vertical portion engages the strut. This mechanical interlocking works effectively with rigid bars (steel, aluminum) rather than relying on friction with deformable materials.
3Reliability
If traditional clamps are used at upper strut ends, then anchoring can be achieved, but the process is time-consuming and requires specialized working means, reducing productivity
Solution Approach 1:
The L-shaped fastening element is designed to be pre-positioned at the lower end of the strut before the anchoring bar is installed. This preliminary placement allows the operator to simply slide the anchoring bar into the fastening element without complex manipulation or elevated access, significantly reducing installation time while maintaining secure anchoring.

AI summary
Anchoring system for formwork struts comprising a male element with a seat for joining the head of a strut and at least one pin, the seat and the pin being configured so that when in use, the pin is perpendicular to the plane containing the two struts to be anchored together, the pin having a protuberance at the end, as well as a female element comprising a bar with a flat surface, said flat surface comprising a slot perpendicular to the longitudinal dimension of the bar, with a width smaller than that of the protuberance and at least one portion with a width larger than that of the pin, comprising an opening for the introduction of the pin in the slot in a position, such that when in use, the opening is located in a position lower than the slot and the pin is fastened in an upper area of the slot.
