Formwork Connection Assembly for Easy Bolt Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork systems face difficulties in removing and replacing bolts, particularly when dealing with different bolt types, requiring specific formwork assemblies and additional tools, which is inconvenient and inefficient.
Innovation Solution
A connection assembly featuring a counterplate with varying surface heights, a bolt block insert, and a wingnut-sleeve system that allows for easy bolt removal and replacement without the need for specific formwork assemblies, utilizing a rotational mechanism to disengage the bolt during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolts are used to engage formwork elements, then the connection strength is improved, but the ease of removing and replacing bolts deteriorates
Solution Approach 1:
The connection assembly is divided into separate components: a counterplate with aperture, a bolt block insert with recess, and a bolt. This segmentation allows the bolt block insert to be removed and replaced independently, facilitating easy bolt removal and replacement while maintaining strong connections during use.
Solution Approach 2:
The counterplate incorporates a plurality of surfaces at differing heights that can be selectively engaged with the waler front face. This dynamic configuration allows the assembly to adapt between a secured state (first surface engaged) and a removal state (second surface engaged), enabling easy bolt replacement without compromising connection strength during operation.
2Adaptability or versatility
If specific formwork assemblies are used for different bolt types, then the adaptability to various bolt types is improved, but the device complexity deteriorates
Solution Approach 1:
The counterplate and bolt block insert design creates a universal connection assembly that can accommodate different bolt types through the standardized aperture-recess-bolt interface. The plurality of surfaces on the counterplate provides multiple engagement options, allowing the same assembly to work with various bolt configurations without requiring separate formwork assemblies for each bolt type.

AI summary
A connection assembly for formwork elements includes a counterplate, a bolt, and a bolt block. The counterplate can include a plurality of surfaces having differing heights that selectively engage with a waler during engagement or disengagement of the bolt from the formwork element. The formwork element can include a J-shaped waler that allows for easy climbing and/or hanging of objects on a site. The connection assembly can include a bolt block that removably engages a formwork element.
