Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for sealing building joints between drywall and ceilings, such as using sealing compounds or dry construction profiles with intumescent elements, fail to provide sufficient movement absorption and often negatively impact the appearance of the joint.
Innovation Solution
A fire protection profile with a profile element featuring an inner and outer section, a curved section, and a wing section, where the wing section is connected to the inner section via the curved section, incorporating intumescent elements for flexibility and deformability, allowing for expansion movement compensation while maintaining aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing compound is introduced into the existing gap, then fire protection is provided, but movement absorption is limited due to hardening and processing cost is high
Solution Approach 1:
The profile element is designed with a curved section that can dynamically deform to accommodate joint movement. The curved section acts as a flexible element that bends and returns, allowing the profile to adapt to changes in joint extent while maintaining fire protection through the integrated intumescent material.
Solution Approach 2:
The profile combines a plastic profile element with integrated intumescent material to create a composite structure. This composite design provides both the mechanical flexibility needed for movement absorption and the fire protection required for safety, eliminating the need for separate sealing compounds.
2Reliability
If dry construction profiles with intumescent elements are used, then fire protection is provided, but movement absorption is insufficient and appearance is negatively affected
Solution Approach 1:
The curved section is designed with specific geometric properties that enable it to deform smoothly under movement forces. The curvature allows the profile to bend and return to its original position, providing effective movement absorption while maintaining a clean, aesthetically pleasing appearance at the joint.
Solution Approach 2:
The profile element has different wall thicknesses in different sections: the curved section has a thinner wall to maximize flexibility and movement absorption, while the inner and wing sections have thicker walls to provide structural support and fire protection. This local variation in quality optimizes both movement absorption and fire protection.
3Adaptability or versatility
If the curved section has thinner wall thickness, then flexibility and deformability are improved for movement absorption, but structural stability may be reduced
Solution Approach 1:
The profile element is designed with non-uniform wall thickness, where the curved section has a thinner wall to maximize flexibility and movement absorption capability. In contrast, the inner section and wing section have thicker walls to provide structural stability and support. This local differentiation allows each section to optimize its function without compromising the overall structure.
Solution Approach 2:
The profile is divided into distinct functional sections: the curved section for movement absorption, the inner section for structural support, and the wing section for attachment. Each segment has optimized wall thickness appropriate to its specific function, allowing the thin-walled curved section to be flexible while the thicker-walled other sections maintain stability.
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 solution provides effective fire protection, large movement absorption, and an attractive appearance by allowing the profile to deform without applying excessive force, ensuring the joint remains sealed and visually unobtrusive.
Implementation Method 1
at least one intumescent element made of intumescent material is provided
Implementation Method 2
The deformation properties of the curved section can be easily adjusted via the wall thickness, with a thinner wall thickness resulting in greater flexibility and thus defined elastic deformation with less force applied

AI summary
The invention relates to a fireproof profile for sealing a structural joint, in particular a connection joint between a dry wall and a ceiling, having a profiled element (18) which has an inner face (30) and an outer face (28) arranged opposite the inner face (30) and comprises an inner section (22), at least one arc section (24), and at least one side section (26). The side section (26) is connected to the inner section (22) via the arc section (24). The fireproof profile (10) additionally comprises at least one intumescent element (20) made of an intumescent material. The arc section (24) has a wall thickness which optionally differs from the wall thickness of the inner section (22) and/or of the side section (26).
