Cornice Formwork Independent Inner Element Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork systems for constructing cornice caps are complex to operate, particularly during erection and stripping.
Innovation Solution
The inner formwork element is connected independently of the support bracket, allowing for easier assembly and adjustment, with the outer and bottom formwork elements being removable first, simplifying stripping and providing more space for safe detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the inner formwork element is connected to the support bracket together with the outer and bottom formwork elements, then the formwork structure is more integrated and stable, but the operation complexity increases significantly during erection and stripping
Solution Approach 1:
The formwork system is divided into independent connection paths: outer and bottom formwork elements connect to the support bracket, while the inner formwork element connects independently to the support element. This segmentation allows the outer and bottom elements to be removed first during stripping, creating space and access for safely removing the inner element without having to manipulate the entire formwork assembly simultaneously.
2Ease of operation
If the inner formwork element is connected independently to the support element, then assembly and adjustment become easier with more space for stripping, but the structural integration and stability are reduced
Solution Approach 1:
The support bracket and support element are both connected to the supporting element (cantilever slab), creating a merged load-bearing system. The outer and bottom formwork elements are fastened to the support bracket, while the inner formwork element is fastened to the support element. This merging of support structures maintains overall stability while allowing independent operation of the inner formwork element during assembly and stripping.
