Transition Coupling Assembly for Concrete-Slab Pipe Stub Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In concrete floor installations, existing methods require manual 'boxing out' around vertical pipes using foam or spacers, which is inefficient and not optimal for ensuring pipes remain submerged during the concrete pouring process.
Innovation Solution
A transition coupling assembly with specific inner wall sections and protuberances that accommodate vertical pipes, allowing for seamless integration with additional pipes post-concrete installation, ensuring a continuous surface and efficient pipe positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual boxing out with foam or spacers is used around vertical pipes, then pipes can be positioned during concrete pouring, but the installation process becomes inefficient and time-consuming
Solution Approach 1:
The transition coupling assembly is pre-assembled with the vertical pipe before concrete pouring. The assembly includes a base portion with recesses that are prepared in advance to receive the pipe, eliminating the need for time-consuming manual boxing out during the concrete installation process. This preliminary preparation significantly improves installation efficiency while reducing the time loss associated with manual spacer application.
2Ease of operation
If manual spacers are used to position pipes, then pipe positioning is achieved, but the process becomes complex and labor-intensive
Solution Approach 1:
The invention merges the base portion, positioning recesses, and transition coupling into a single integrated assembly. The base portion includes recesses that directly receive and position the vertical pipe, eliminating the need for separate foam or spacer materials. This consolidation simplifies the overall system, reduces the number of components, and makes the pipe positioning process easier to operate while reducing device complexity.
3Reliability
If foam or spacer material is used to box out pipes, then pipes remain submerged during concrete pouring, but additional materials and steps are required
Solution Approach 1:
The base portion serves multiple functions: it provides a stable foundation, includes recesses for pipe positioning, and acts as a formwork element during concrete pouring. The transition coupling assembly integrates these functions into a single component system, eliminating the need for separate foam or spacer materials. This multi-functionality ensures reliable pipe submersion during concrete pouring while reducing the number of materials and steps required in the installation process.

AI summary
A transition coupling assembly for use in the construction of a concrete floor containing vertical pipe stubs. A transition coupling body is used to cap a vertical pipe during the pouring of the slab. After the concrete floor is finished, a thin layer of concrete may be removed from above the cover and then the cover is removed to reveal an opening leading to the second end of the coupling. A second pipe may be connected to a second socket in the transition coupling to form a vertical pipe stub to provide a waste pipe for a toilet, sink, or other plumbing fixture.
