Base Plate Feedthrough Assembly for Flush Pipe Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing penetration fittings for routing pipes through foundation slabs often require additional work to trim or support overhanging sections, posing safety risks and inefficiencies, especially when the final floor height is unknown during slab pouring.
Innovation Solution
A feedthrough assembly with a casing pipe and base body is cast into the base plate such that the side wall protrudes no more than 5 cm, allowing a cavity to be maintained above the pipe, enabling a mounting bracket to be flush with the floor structure, thus preventing overhangs and ensuring safety and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the casing pipe is provided with excess height to ensure it extends above the finished floor level, then the pipe routing is guaranteed, but additional trimming work is required and safety risks arise from potential overhangs
Solution Approach 1:
The patent changes the height parameter of the base body to be minimal (max 5 cm protrusion) rather than providing excess height. This parameter optimization eliminates the need for trimming while ensuring the pipe routing function is maintained through the mounting bracket that extends the pipe stub to the required height.
Solution Approach 2:
The mounting bracket with pipe socket is designed to be attached after the base plate is cast, extending the pipe stub upwards to the required height. This preliminary preparation of the mounting structure eliminates the need for post-installation trimming of the casing pipe.
2Ease of operation
If the side wall protrudes significantly from the base plate, then the cavity is easily accessible, but the floor structure cannot be properly built and safety is compromised
Solution Approach 1:
The patent optimizes the protrusion parameter of the side wall to a minimal value (maximum 5 cm) from the base plate. This limited protrusion is sufficient to maintain cavity accessibility during construction while allowing the floor structure to be properly built, eliminating fire safety risks associated with significant overhangs.
3Adaptability or versatility
If the base body is cast with large overhang to accommodate unknown floor height, then installation flexibility is improved, but post-installation trimming and support work increases
Solution Approach 1:
The patent changes the overhang parameter to a minimal value (max 5 cm) that provides sufficient installation flexibility for accommodating the cavity, while eliminating the need for post-installation trimming and support work. The mounting bracket attached afterward provides the necessary adaptability for pipe routing.
4Reliability
If the mounting bracket is positioned flush with the floor structure, then fire safety is improved by shielding the casing pipe, but the bracket must be precisely positioned
Solution Approach 1:
The mounting bracket is designed to be attached after the base plate is cast, with the flange plate positioned on the floor structure. This preliminary positioning allows the bracket to be flush with the floor structure, providing fire safety by shielding the casing pipe, while the modular design facilitates precise positioning.

AI summary
The invention relates to the use of a feedthrough for casting into a base plate and passing a conduit through it, the feedthrough comprising a sheathing tube and a base body arranged at an upper end of the sheathing tube, the base body having a bottom part and a side wall and thus forming a cavity at the upper end of the sheathing tube, the sheathing tube and the base body being cast into the base plate in such a way that the side wall projects beyond an upper edge of the base plate by a maximum of 5 cm, and after the base plate has been cast, a floor structure being built on it, a cavity being left free at the upper end of the sheathing tube, and after the base plate has been cast, the conduit being laid through the sheathing tube, a pipe stub of a mounting attachment extending the sheathing tube upwards.
