Cast-In Floor Penetration Insert for Angled Pipe Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor duct systems lack effective solutions for angled pipe routing and safety during construction phases, particularly in scenarios where there is a risk of accidents from uneven surfaces and delayed pipe system construction.
Innovation Solution
A floor duct system featuring a hollow body with an insert that provides a recess for angled pipe routing and includes a hard plastic insert with a stepped design for step protection, which can withstand significant surface loads and includes features for drainage and assembly aids like a spirit level and breakable sections for easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a floor penetration is cast into a base plate together with a pipe element, then the pipe system can be installed through the foundation slab, but the pipe element creates a protruding surface that poses safety risks during construction
Solution Approach 1:
An insert element is introduced as an intermediary component that temporarily covers the hollow body of the floor penetration. This insert with its upper cover plate creates a flush surface with the base plate top surface, eliminating the hazard of protruding pipe elements during construction while allowing safe worker movement.
2Adaptability or versatility
If the pipe element extends through the foundation slab, then wastewater can be conveyed outside the building, but horizontal offsets require complex pipe routing solutions
Solution Approach 1:
The hollow body is pre-formed as part of the floor penetration structure during base plate casting. This preliminary preparation creates a recess space that later accommodates angled pipe guides, allowing horizontal offsets to be compensated without requiring complex pipe routing solutions during subsequent installation.
3Adaptability or versatility
If the hollow body recess is larger than the pipe element outer diameter, then angled pipe guides can compensate for offsets, but the larger opening increases exposure to contaminants during construction
Solution Approach 1:
The insert serves as a temporary intermediary cover that closes the hollow body opening during construction phases. This allows the hollow body to maintain its larger recess dimension for future angled pipe routing while the insert prevents contaminant entry into the pipe system during the construction period.
4Reliability
If the insert is designed to withstand high surface loads for safety, then worker safety is improved, but the insert material and design become more complex
Solution Approach 1:
The insert is manufactured from rigid plastic material that combines sufficient load-bearing capacity with ease of formation. This material choice allows the insert to withstand high surface loads for worker safety while maintaining a relatively simple single-piece construction without requiring complex multi-material composite structures.

AI summary
The invention relates to the use of a floor penetration (1, 30) with a hollow body (1) for attaching to a pipe element (2) and together with it being cast in a base plate (3), in which the hollow body (1) is placed at one end of the pipe element (2) and then at this end, which after casting lies axially within the base plate (3) with respect to a longitudinal axis (6) of the pipe element (2), provides a recess (25) in the base plate (3), which extends axially to an upper side surface (3a) of the base plate (3) and has a diameter there that is larger than an outer diameter of the pipe element (2), wherein the floor penetration (1, 30) further comprises an insert (30) which is arranged in the hollow body (1).
