Compressed Fire Protection Profiles for Tight Firewall Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing firewalls in structural openings face a conflict between easy installation and effective sealing, as the firewall must tightly fit against boundary surfaces to achieve fire protection without compromising manufacturability.
Innovation Solution
A method using a fire protection profile comprising a composite material tube filled with an intumescent material, where the profile is initially compressed to facilitate easy insertion into the opening and then decompressed to ensure tight sealing against the opening's boundary surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fire protection profile is made to tightly fit against boundary surfaces for effective sealing, then fire protection reliability is improved, but installation ease and manufacturability deteriorate
Solution Approach 1:
The fire protection profile is designed with dynamic characteristics, being elastically deformable and compressible during installation, then expanding to tightly seal against boundary surfaces. This allows the profile to transition from an easily installable compressed state to a reliably sealing expanded state, resolving the contradiction between installation ease and sealing effectiveness
Solution Approach 2:
The profile's physical parameters (volume, shape, density) are changed through compression during installation to facilitate easy placement, then return to their original state to achieve tight sealing. This parameter transformation enables the profile to satisfy both easy installation and effective sealing requirements at different stages
2Ease of operation
If the fire protection profile is compressed to facilitate installation, then installation ease is improved, but sealing effectiveness may deteriorate if not properly released
Solution Approach 1:
The profile is preliminarily compressed before installation to facilitate easy placement into the opening. After installation, the compression is released to allow the profile to expand and achieve its full sealing potential. This preliminary action sequence ensures both easy installation and reliable sealing without compromise
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method allows for easy and efficient installation of fire protection profiles while ensuring a reliable fire protection seal, even in varying opening geometries and under conditions of relative movement between the opening and adjacent structures.
Implementation Method 1
The fire protection material of the fire protection profile preferably comprises an intumescent material. Such a material increases in volume under the action of heat.
Implementation Method 2
The fire protection profile is therefore elastically deformable. This means that in particular the fire protection material must also be elastically deformable.

AI summary
A method can be used for producing a firewall in an opening of a building. In this case, at least one fire protection profile is used which contains a tube made of a composite material, which is filled with a fire protection material. The fire protection profile is designed such that it can be combined with an adjacent fire protection profile in the event of a fire. In order to produce the firewall, it is first transferred into an at least partially compressed state or provided in such a state. The fire protection profile is then introduced into the opening, with the at least partially compressed state being maintained. The fire protection profile is subsequently released so that it is decompressed at least partially and at least in portions.
