Adjustable Firestop Tube Seal for Wall Penetrations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection devices for sealing penetrations in walls, such as cable ducts, are difficult to install, result in material waste, and do not provide an attractive finish, while being vulnerable to dust and humidity.
Innovation Solution
A fire protection device comprising an elongated tube with a moveable sealing portion and intumescent sealing material, which is easy to install and provides structural support to tubular objects, ensuring a tight seal against air and smoke, and features a threaded connection for precise positioning and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If modelling compounds or cable discs are used for sealing penetrations, then the material is highly flexible and relatively easy to install, but the finish is not attractive and the material is vulnerable to dust and humidity
Solution Approach 1:
The fire protection device combines a metal tube with a sealing portion comprising sealing material, creating a composite structure that integrates the flexibility and ease of installation of traditional materials with the durability and aesthetic finish of metal components
Solution Approach 2:
The sealing portion is designed as a flexible component that can be moved along the tube to achieve proper positioning, maintaining the adaptability of traditional sealing materials while being protected by the rigid metal tube structure
2Shape
If firestop sealants or foams are used for sealing penetrations, then a satisfactory finish can be achieved, but special tooling is required and the application requires a lot of time and results in significant material waste
Solution Approach 1:
The sealing portion with sealing material is pre-formed and attached to the tube before installation, eliminating the need for on-site application tools and reducing installation time while maintaining aesthetic finish
Solution Approach 2:
The device is divided into separate components (tube and sealing portion) that can be independently manufactured and assembled, allowing for efficient production and quick installation without requiring special tooling
3Reliability
If the sealing portion is fixed directly to the wall opening, then a tight seal can be achieved, but the device lacks ease of installation and adjustment
Solution Approach 1:
The sealing portion is designed to be movable along the tube, allowing dynamic adjustment during installation to achieve proper positioning and a tight seal against the wall opening, while maintaining ease of installation
4Ease of operation
If the tubular object lacks additional support, then the installation is simpler, but the tubular object may bend and compromise the sealing effectiveness
Solution Approach 1:
The tube serves multiple functions: it provides structural support to prevent bending of the tubular object, acts as a mounting surface for the sealing portion, and contributes to the overall fire protection function, thereby maintaining installation simplicity while ensuring structural stability
