Prefabricated Concrete Connection Anchoring Means Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mechanical connections for prefabricated reinforced concrete articles face difficulties in assembly due to projecting male elements, which complicate the insertion of reinforcement and exceed safe lifting limits due to increased weight when anchoring means are integrated with plates during production.
Innovation Solution
The anchoring means are produced separately and inserted through flared holes in the plates, allowing easier reinforcement placement and reducing weight by enabling bayonet-type connections, thus simplifying the assembly process and adhering to safety regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If anchoring means are integrated with plates during production, then connection strength is improved, but weight increases beyond safe lifting limits
Solution Approach 1:
The anchoring means are separated from the plates into independent components. The plates can be produced and handled separately from the anchoring bars, allowing the plates to remain within safe lifting weights while the anchoring means are added later during assembly, thus resolving the contradiction between connection strength and handling weight
2Adaptability or versatility
If male connection elements project from the first article, then connection capability is improved, but assembly difficulty increases due to interference with reinforcement insertion
Solution Approach 1:
The reinforcement is inserted into the formwork before the anchoring means are positioned. This preliminary action allows the reinforcement to be placed without interference from the anchoring bars, which are added later. The connection capability is maintained because the anchoring means are still integrated into the final assembly, but the assembly difficulty is reduced by eliminating interference during the critical reinforcement insertion phase

AI summary
The mechanical connection for prefabricated reinforced concrete articles comprises: a first plate (1) from which first anchoring means (3) project into a first article (30); a second plate (2) from which second anchoring means (4) project into a second article (31); means for fixing the first plate (1) to the second plate (2), comprising at least one female element (10-12) fixed to the second plate (2) such that the second front surface (6) is free, each female element (10-12) being accessible from the outside and being able to cooperate with a corresponding male element (13-15) removably coupled to the first plate (1) and adapted to cooperate with a corresponding anchoring hole (16-18) provided therein. The anchoring means (3, 4) are separate and are separated from the respective plates (1, 2), connection means (50, 56, 55) being provided, of the type which enables the anchoring means (3, 4) to be connected to the respective plates (1, 2) when necessary.
