Support Waler Hinge Mechanism for Formwork Striking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In column formwork systems, increased strain at seams during concrete pouring makes it difficult to strike the formwork from the concrete structure, posing a challenge for efficient and safe removal.
Innovation Solution
A support waler system with a horizontal fixation element that engages with formwork panels, allowing for rotation and deflection to relieve pressure on vertical fixation elements, enabling their easy removal after concrete curing, thereby facilitating safer and more efficient formwork striking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional formwork support systems are used during concrete pouring, then the formwork provides structural support, but the increased strain at seams makes it difficult to strike the formwork from the concrete structure
Solution Approach 1:
The support waler is segmented into a first portion and a second portion that can rotate relative to each other about a hinge. This segmentation allows the waler to deflect and relieve pressure on vertical fixation elements at the seams during striking, enabling easier removal while maintaining structural support during pouring
Solution Approach 2:
The support waler transitions from a rigid structure during concrete pouring to a dynamic, deflectable structure during striking. The hinge mechanism enables the waler to rotate and absorb strain, transforming the system from static to dynamic to facilitate easier formwork removal
2Stability of the object's composition
If the support waler is rigid to maintain structural support, then the formwork remains stable during pouring, but the vertical fixation elements cannot be freely removed after curing
Solution Approach 1:
The support waler is divided into segments connected by a hinge, allowing differential movement between portions. This enables the structure to maintain overall stability during pouring while allowing localized deflection during striking to facilitate removal of vertical fixation elements
Solution Approach 2:
The support waler changes its structural parameter from rigid to flexible through the hinge mechanism. During pouring, the waler maintains rigidity for stability; during striking, the hinge allows rotation and deflection, changing the structural parameter to enable easy removal of fixation elements
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The support waler system allows for easier and safer striking of formwork by relieving pressure on vertical fixation elements, making the process more efficient and reducing the risk of damage or injury.
Implementation Method 1
rotation of the horizontal fixation element causes relative deflection of the first panel or the second panel toward or away from each other, thereby relieving pressure on at least one of the vertical fixation elements
