Attachment Piece and Insert for Pipe Integration in Concrete Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for integrating pipes into wall or floor elements during construction, such as using double sleeves, are prone to fitting issues, contamination, and blockages, especially with sewer pipes, due to fixed lengths and susceptibility to debris accumulation.
Innovation Solution
A method involving an attachment piece with a contact section and a free holding section, combined with an insert piece, allows for the integration of a standard pipe with a socket and spigot end into the wall or floor element, enabling easier adjustment and reducing contamination risks by using a soft material attachment piece and a stabilizing insert piece, which can be made of synthetic rubber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If double sleeves with fixed lengths are used to integrate pipes into wall elements, then the pipe integration is achieved, but fitting issues occur due to deviations in wall thickness and the device complexity increases
Solution Approach 1:
The attachment piece is divided into two functional sections: a contact section for securing to the pipe and a free holding section for receiving the insert piece. This segmentation allows each part to perform its specific function optimally while keeping the overall system simple.
Solution Approach 2:
The insert piece acts as an intermediary element between the attachment piece and the pipe. It provides the necessary spacing and support during concreting, enabling the attachment piece to maintain constant distance from the pipe outer surface without requiring complex adjustable mechanisms.
2Reliability
If double sockets are used for pipe integration, then the pipe can be integrated into the wall, but contamination and blockages occur due to susceptibility to debris accumulation
Solution Approach 1:
The harmful feature of having open sockets susceptible to contamination is eliminated by removing the socket structure entirely. Instead, the attachment piece secures directly to the pipe outer surface, and the insert piece fills the spacing volume, preventing debris accumulation while maintaining pipe functionality.
3Ease of manufacture
If specialized components are used for pipe integration during casting, then the pipe can be securely integrated, but the ease of manufacture decreases due to availability issues
Solution Approach 1:
The attachment piece is designed as a universal component that can be used with standard pipes during wall concreting operations. It performs multiple functions: securing to the pipe, maintaining spacing, and enabling easy removal after concreting. This multi-functionality eliminates the need for specialized single-purpose components.
Solution Approach 2:
The insert piece is designed as a temporary, disposable element that serves its purpose during concreting and is then removed. It provides necessary structural support during the critical concreting phase but is not intended for long-term use, reducing costs and simplifying the overall system.
4Stability of the object's composition
If rigid attachment pieces are used for pipe integration, then the structural stability is improved, but the ease of operation decreases due to difficulty in assembly
Solution Approach 1:
The attachment piece material properties are optimized by selecting rubber with specific Shore hardness values (40-70 Shore). This parameter selection provides the ideal balance: soft enough for easy assembly and pipe mounting, yet rigid enough to maintain structural stability during concreting operations.
