Conduit Installation Bearing Element for Wall Casting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for integrating a line, such as a pipeline, into a wall or floor element during concrete casting face challenges with attachment piece hardness leading to potential damage or loosening due to pressure and buoyancy issues, which can result in grouting material penetration and misalignment.
Innovation Solution
A method involving an attachment piece with a softer bearing element, having a lower Shore hardness than the attachment piece, is used to structurally integrate the line by casting with the attachment piece keeping a recess free in the solidified material, allowing for flexibility and secure mounting to compensate for offsets and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard attachment piece is used to withstand the pressure of casting material, then the attachment piece can maintain structural integrity, but it may be damaged or loosened during assembly due to forces applied to it
Solution Approach 1:
A bearing element is introduced as an intermediary component between the attachment piece and the pipeline. This bearing element absorbs and distributes forces applied during assembly, preventing direct transmission of forces to the attachment piece. The bearing element acts as a buffer that protects the attachment piece from damage while maintaining the overall structural integrity of the assembly.
Solution Approach 2:
The attachment assembly utilizes a composite structure combining the attachment piece (made of a rigid material for strength) with the bearing element (made of a softer, more compliant material). This composite approach allows the hard attachment piece to withstand casting pressure while the softer bearing element provides protection against assembly forces and potential damage.
2Manufacturing precision
If a hard attachment piece is used to keep the recess free during casting, then the recess remains clear, but grouting material can penetrate into the attachment piece causing damage
Solution Approach 1:
The bearing element serves as a protective intermediary between the attachment piece and the external environment. It prevents grouting material from directly contacting and penetrating into the attachment piece, while still allowing the attachment piece to maintain the recess clear during the casting process.
Solution Approach 2:
The bearing element is installed in advance to provide protective cushioning to the attachment piece. This pre-installed protective layer prevents harmful grouting material from reaching the attachment piece before any potential penetration can occur.
3Stability of the object's composition
If the attachment piece is fastened to formwork to prevent floating, then positioning stability is improved, but forces from formwork movement can still transmit to the attachment piece causing damage
Solution Approach 1:
The bearing element acts as a force-isolating intermediary between the attachment piece and the formwork. Even when the formwork moves or applies forces during casting, the bearing element absorbs these forces and prevents their direct transmission to the attachment piece, maintaining both stability and reliability.
Solution Approach 2:
The bearing element changes the mechanical parameters of the connection between the attachment piece and the formwork. By introducing a compliant element, the system transitions from a rigid connection that transmits all forces to a semi-compliant connection that filters and absorbs harmful forces while maintaining positional stability.
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
This approach ensures secure integration of the line with the ability to compensate for offsets and prevent damage during the casting process, maintaining the line's position and integrity within the wall or floor element.
Implementation Method 1
the bearing element can react to the action of force with at least a certain deformation ('bearing function'), which means that damage can be prevented
Implementation Method 2
casting with initially free-flowing and then solidifying casting material
