Adjustable Formwork Runner Holder with Wedge Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard formwork beams have a fixed length, which often requires cutting or overlapping to match the required length, leading to increased strut numbers and reduced space for operators, making it difficult to work in monolithic structures with small spans.
Innovation Solution
An adjustable runner holder with pressure means, featuring an oblique cut and wedge mechanism, allowing for continuous length adjustment between vertical structures, reducing the need for multiple struts and facilitating easier assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard fixed-length beams are used, then manufacturing and inventory management are simplified, but the beams cannot adapt to varying required lengths without cutting or overlapping
Solution Approach 1:
The runner holder is divided into multiple telescopic sections that can slide relative to each other, allowing the beam to extend or retract to different lengths. The segmentation enables continuous length adjustment while maintaining a compact stored configuration.
Solution Approach 2:
The runner holder transitions from a static fixed-length structure to a dynamic telescopic structure that can adjust its length. The telescopic mechanism allows the beam to dynamically adapt its length to match the required span between formworks.
2Manufacturing precision
If beams are cut to join them to achieve required length, then length precision is improved, but the number of struts increases and working space decreases
Solution Approach 1:
A single telescopic runner holder can replace multiple fixed-length beams and struts. By adjusting its length, one universal beam can span different distances, eliminating the need for additional struts that would be required when using multiple shorter beams joined together.
3Reliability
If overlapping beam positioning is used, then continuous support is achieved, but the number of struts increases and space between struts decreases
Solution Approach 1:
The telescopic runner holder provides continuous support through its ability to dynamically adjust its length, eliminating the need for overlapping beams. The single adjustable beam can span the entire required distance without gaps, maintaining support continuity while freeing up working space.
4Strength
If multiple struts are used to support fixed-length beams, then structural support is ensured, but the passage of operators becomes difficult
Solution Approach 1:
The telescopic runner holder serves as a universal support element that can span varying distances without requiring multiple struts. By adjusting its length, a single runner holder can provide the necessary structural support across different spans, reducing the number of struts from three to two and improving operator passage.

Implementation Method 1
The pressure means according to the invention comprises an oblique cut at one or both of the ends of the runner holder which cut co-operates with a wedge of the pressure means in establishing the pressure on the horizontal structure or wall.

AI summary
The invention relates to a runner holder divided into a first part and a second part, the first part comprising a first end of the runner holder and the second part comprising a second end of the runner holder, opposite the first end, the first part having a projection inserted into an inlet of the second part, which projection can slide into the entrance such that the length of the runner holder can be adjusted. The runner holder further comprises at least one pressure means situated at the first end and/or the second end.
