Fire-Resistant Profile Frame Construction With Intumescent Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-resistant metal profile frameworks have limited fire resistance due to the limited water storage capacity of their fire protection inserts, which restricts their effectiveness in high-temperature conditions.
Innovation Solution
Implementing an intumescent fire protection coating on components of the profile frame construction, such as insulating bars and inserts, which forms a foam layer to insulate and delay heat transfer during a fire, combined with optional fire protection inserts that expand or contain a high water content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire protection inserts with high water content are used in hollow profiles, then fire resistance is improved through cooling effect, but the internal space of hollow profiles is limited and cannot be increased indefinitely
Solution Approach 1:
The fire protection insert is nested inside the hollow profile, utilizing the available internal space efficiently. The insert is positioned within the profile cavity to maximize the cooling effect while maintaining structural integrity and not exceeding the profile's internal volume constraints.
2Reliability
If insulating bars are coated with fire protection coating, then fire resistance is improved through thermal insulation, but the complexity of manufacturing increases
Solution Approach 1:
The fire protection coating is applied selectively to specific regions of the insulating bars rather than uniformly across all surfaces. This localized coating approach focuses the fire protection where it is most needed at critical connection points and heat transfer zones, reducing material consumption and simplifying the coating process while maintaining effective fire resistance.
3Reliability
If intumescent fire protection coating is applied to insulating bars, then fire resistance is improved through foam layer formation, but the application process becomes more complex
Solution Approach 1:
The intumescent fire protection coating is formulated to automatically activate and expand into a protective foam layer when exposed to fire temperatures, without requiring external activation mechanisms or complex application processes. The coating self-regulates its protective function based on temperature conditions, simplifying both application and operation while ensuring reliable fire protection.
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
Enhances fire resistance and extends the service life of the construction by providing effective thermal insulation and delaying disintegration, even with minimal coating thicknesses.
Implementation Method 1
the intumescent fire protection coating foams up in the event of a fire under the influence of a certain temperature. This foaming of the fire protection coating prevents or at least impedes the transfer of heat to the coated component
Implementation Method 2
If the framework or the fire protection inserts are exposed to a temperature above approximately 85°C, the water of crystallization is released and can cool the framework

AI summary
The invention relates to a profile frame construction (1), in particular for windows or doors in a fire-resistant design, in which two or more hollow profiles (2, 3) made of metal, in particular aluminum, are connected to one another via heat-insulating insulating webs (4). In order to ensure that the profile frame construction (1) has increased resistance to the effects of fire, the invention provides that at least one of the insulating webs (4), and preferably all insulating webs (4) of the profile frame construction (1), is/are at least partially or regionally provided with an insulating layer-forming fire-protection coating (100), and in particular coated.
