Slidable Rod Barrier for Concrete Penetration Sealing

Solution Overview

Problem

Existing methods for creating portals in poured concrete flooring, such as core drilling and boxing out, face issues like cold joints, material limitations, and inefficiencies, particularly with the sleeve method which can be time-consuming and prone to errors due to the difficulty in manipulating and cutting ferrous materials.

Innovation Solution

A collar and slidable rod system made of plastic, with interlocking features and anchoring capabilities, that forms a continuous barrier conforming to the decking contours, allowing for efficient creation of penetrations without the drawbacks of traditional methods, and includes sealing materials to prevent concrete flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the sleeve method is used to create penetrations, then cold joints are avoided, but the process becomes time-consuming and difficult to manipulate due to ferrous materials

Engineering Contradiction:

Improveavoidance of cold jointsVSAvoiddifficulty in manipulating and cutting ferrous materials

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent changes the material parameter from ferrous (metal) to non-ferrous (PVC plastic), which fundamentally alters the workability and cutting characteristics while maintaining the structural integrity needed to prevent cold joints during concrete pouring

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs disposable PVC sleeves and filler materials that are inexpensive and can be easily discarded or replaced if needed, eliminating the complexity of manipulating durable ferrous materials while still achieving the goal of preventing cold joints

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Strength

If ferrous sleeve materials are used, then structural strength is maintained, but cutting and manipulation becomes difficult and time-consuming

Engineering Contradiction:

Improvestructural strength of sleeve materialVSAvoidtime required for cutting and installation

Core Design Contradiction:

AI summary

A method for creating a feed through construction barrier comprised of a collar defining the form factor of the barrier and a plurality of slidably connected and nested rods creating a continuous barrier conforming to the form factor of the collar. While the collar defines the form factor of the barrier, the slidable rods can be adjusted in their relative positions along the form factor to provide for a barrier that conforms to the contours of the application surface. The barrier may include means to attach the apparatus to the decking and caps to seal the apparatus during construction activities. The rods are interconnected one to another so that the rods can be connected into a continuous barrier. The rods are able to slide relative to each other along the interlocking structure. When the device is set into position, rods may be slid into a barrier structure that conforms to both planar and non-planar surfaces of the application surface. As such, the method provides for an effective barrier for further construction processes, e.g. pouring a cement floor while keeping cement from flowing into the desired channel or penetration.
