Line Feed-Through Sealing Structure for Fire Gas Imperviousness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional line penetrations through building components often fail to ensure complete imperviousness to fire gases and smoke, especially when lines move within the penetration, and existing solutions are not effective for round cross-section lines or multiple lines.
Innovation Solution
A line penetration system with two elastically deformable sealing structures that bear on each other, featuring elongated lamellas or bristles, which adapt to the line's position and cross-section, ensuring sealing against fire gases and smoke, even when the line moves, and allowing multiple lines to be routed without compromising the seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sealing compounds or single lamella curtains are used, then the sealing structure is simple, but complete imperviousness to fire gases and smoke cannot be achieved
Solution Approach 1:
The sealing structure is divided into multiple sealing structures (at least two) arranged opposite to each other, with each sealing structure containing multiple elongated lamellas. This segmentation allows the system to achieve complete imperviousness through coordinated action of multiple segments, resolving the contradiction between sealing effectiveness and structural simplicity.
Solution Approach 2:
The sealing arrangement extends into the third dimension by having lamellas protrude from one sealing structure toward the center of the penetration and bear on the opposite sealing structure. This dimensional arrangement creates overlapping sealing surfaces that block fire gases and smoke effectively while maintaining reasonable structural complexity.
2Reliability
If deformable lamellas extend radially toward the central axis, then sealing is achieved for one line, but imperviousness is lost when the line moves transversely
Solution Approach 1:
The lamellas are designed to be elastically deformable, allowing them to dynamically adapt their position and shape in response to line movements. This dynamic characteristic enables the sealing structure to maintain imperviousness whether the line is stationary or moving transversely, resolving the contradiction between sealing reliability and adaptability to line movement.
3Reliability
If a lamella curtain is used for round cross-section lines, then the structure is simple, but complete imperviousness cannot be guaranteed
Solution Approach 1:
Instead of a single continuous curtain, the sealing is segmented into multiple discrete lamellas arranged in at least two sealing structures opposite each other. This segmentation allows the lamellas to conform to round cross-section lines more effectively while maintaining structural organization, achieving complete imperviousness without excessive complexity.
Solution Approach 2:
The elongated lamellas are made of elastically deformable material that can flex and conform to the contours of lines with round cross sections. This flexibility allows the lamellas to adapt to curved surfaces and ensure complete sealing, resolving the contradiction between imperviousness and structural simplicity.
4Reliability
If sealing compound is introduced, then the sealing process is simple, but adequate imperviousness to fire gases and smoke is not achieved
Solution Approach 1:
The patent replaces chemical sealing compounds with a mechanical sealing system consisting of elastically deformable lamellas that physically block fire gases and smoke through their geometric arrangement and elastic deformation. This mechanical approach achieves adequate imperviousness while providing a more reliable and controllable sealing mechanism.
