Prefabricated Wall Removable Receiving Means Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prefabricated walls with integrated formwork pose safety risks during handling due to the need for operators to work at height and the irretrievable loss of connection means, and complex construction requirements, including the use of sophisticated and expensive technology for removal.
Innovation Solution
A prefabricated wall design with removable receiving means that are accessible from the exterior, featuring reversible fixing mechanisms and actuating means, allowing for safe handling and subsequent removal and reuse of connection means without the need for complex orientation or expensive technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection means are introduced inside the internal volume of the wall to be embedded in concrete cast in place, then the wall can be handled, but operators must work at height which poses safety problems and the connection means is irretrievably lost
Solution Approach 1:
The receiving means is extracted from the internal volume of the wall and made accessible from the exterior side. This allows the connection means to be introduced and secured without requiring operators to work at height inside the wall, thereby eliminating the safety risk while preventing loss of connection means through reversible fixing
Solution Approach 2:
The receiving means is designed with reversible fixing to the plates, allowing it to be removed after handling is complete. This enables the recovery and potential reuse of both the receiving means and the connection means, eliminating the irreversible loss that occurs with traditional embedding methods
2Reliability
If a pivoting body with movable pin is used for receiving connection means, then the wall can be handled safely, but the construction becomes complex and expensive technology is required for removal
Solution Approach 1:
The receiving means is divided into separate components: the receiving means itself and the fixing means. This segmentation allows for simpler, independent design and manufacturing of each component, reducing overall complexity while maintaining safe handling through the reversible fixing mechanism
Solution Approach 2:
The reversible fixing mechanism is designed to be simple and cost-effective, replacing the need for expensive electromagnetic pulse systems or complex mechanical release mechanisms. The fixing means can be easily removed after use without requiring sophisticated technology
3Stability of the object's composition
If receiving means are embedded inside the plates of the wall, then the wall structure is maintained, but the receiving means is not accessible for removal and connection means cannot be recovered
Solution Approach 1:
Instead of fully embedding the receiving means inside the plates, the design uses partial embedding with the fixing means accessible from the exterior. This partial action maintains sufficient structural integrity while enabling accessibility for removal and recovery of connection means
