Horizontal Beam With Movable Locking Hook for Concrete Formwork
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing formwork systems for concrete ceilings pose safety risks during assembly and disassembly due to the need for assembly from elevated positions, and they often require complex and costly pivoting mechanisms that compromise stability and prevent early striking, leading to inefficient use of materials.
Innovation Solution
A horizontal beam with a movable latching hook allows assembly and disassembly from below, enabling early striking and efficient reuse of materials, while maintaining stability through secure engagement with ceiling supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If assembly is performed from elevated positions using traditional formwork systems, then the formwork can be assembled to support concrete ceilings, but safety risks increase due to the risk of falls and hazards from falling parts
Solution Approach 1:
The patent inverts the traditional assembly approach by enabling formwork assembly from below instead of from above. The horizontal beam can be swung up from a horizontal position to a vertical position, allowing installers to work from ground level rather than elevated positions, thereby eliminating fall risks while maintaining proper formwork assembly
2Reliability
If pivoting mechanisms are used to enable assembly from below, then safety is improved, but the construction becomes more complex and costly
Solution Approach 1:
The patent segments the formwork system into modular components (horizontal beams, ceiling supports, formwork panels) that can be independently assembled. The horizontal beam is designed as a separate component with integrated locking hooks, allowing it to be swung up and locked into position without requiring complex pivoting mechanisms, thus simplifying the overall construction
3Ease of operation
If complex pivoting mechanisms are used, then assembly from below is enabled, but stability is compromised and early striking is prevented
Solution Approach 1:
The patent introduces dynamic locking mechanisms where the locking hooks can move between locked and unlocked positions. This allows the horizontal beam to be dynamically assembled from below, then securely locked into a stable position, enabling both ease of operation and formwork stability simultaneously
4Stability of the object's composition
If formwork components remain on site until complete removal, then stability is maintained, but material efficiency decreases and early striking is prevented
Solution Approach 1:
The patent enables preliminary removal of formwork components through the swinging-up mechanism. The horizontal beam can be swung up and locked to ceiling supports, allowing formwork panels to be removed early while maintaining structural stability, thus improving material efficiency without compromising safety
