Adjustable Cornice Formwork Support for Bridge Cantilever Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cornice formwork systems struggle to achieve optimal static properties for diverse cantilever geometries in bridge construction, as they are often designed for specific cantilever shapes, limiting adaptability.
Innovation Solution
A suspension head with adjustable length, allowing connection in multiple mounting positions and telescopic elements, enabling the suspension device to accommodate various cantilever designs by varying the distance between anchoring and compression points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length suspension head is used, then the device structure is simple, but it cannot adapt to different cantilever geometries
Solution Approach 1:
The suspension head incorporates a telescopic mechanism with movable sections that can be extended or retracted to different lengths. This dynamic adjustment capability allows the same suspension head to adapt to various cantilever geometries and span requirements, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The suspension head's key parameter - its length - is made variable through the telescopic mechanism. By changing the length parameter to match different cantilever dimensions, the system achieves versatility across multiple bridge designs without requiring completely different suspension head models for each geometry.
2Stability of the object's composition
If the distance between tension and compression points is maximized, then structural stability is improved, but the device cannot accommodate narrow cantilevers
Solution Approach 1:
The telescopic mechanism enables the distance between tension and compression points to be dynamically adjusted. For wide cantilevers, the suspension head extends to maximize stability; for narrow cantilevers, it retracts to the appropriate length, ensuring both structural stability and adaptability across different bridge geometries.
