Intumescent Fire Insert for Post Joint Heat Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post-and-beam facade constructions lack sufficient fire resistance, particularly in scenarios where the available installation space is limited, and existing solutions do not effectively prevent heat penetration during a fire.
Innovation Solution
A fire protection insert is introduced for the joint between adjacent posts, featuring a central section and opposing leg sections, made of intumescent material that expands upon heat exposure, sealing the gap and enhancing fire resistance by using a T-shaped base body with a thickness of 1.0 mm to 3.0 mm, which can be retrofitted into existing constructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the available installation space is limited, then the fire resistance cannot be arbitrarily increased, but the achievable fire resistance is insufficient for certain requirements
Solution Approach 1:
The patent applies parameter changes by utilizing the intumescent property of the fire protection insert material. When exposed to heat, the material undergoes a parameter change by expanding its volume significantly (from a thin 1.0-3.0mm insert to a much larger expanded state), thereby increasing fire resistance within the limited installation space of the profile cavity
Solution Approach 2:
The fire protection insert material undergoes a phase transition when exposed to fire conditions. The material transitions from a compact, thin-state to an expanded, voluminous state through thermal activation, creating an insulating barrier that prevents heat penetration while occupying minimal space during normal conditions
2Reliability
If a fire protection insert is added to enhance fire resistance, then the structural integrity during fire is improved, but the device complexity increases
Solution Approach 1:
The fire protection insert is merged with the existing profile construction by being received within the cavity of the post profile. The insert is positioned between the first and second post profile pieces and secured in place, integrating fire protection functionality into the existing structural system without requiring separate, additional components
Solution Approach 2:
The fire protection insert is designed to be self-activating through its intumescent properties. When exposed to fire conditions, the material automatically expands and forms an insulating barrier without requiring external activation mechanisms, control systems, or additional components, thereby maintaining simplicity while providing reliable fire protection

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 fire protection insert effectively seals the gap between posts, delaying the disintegration of the construction during a fire by acting as a heat shield, thereby extending the structural integrity and fire resistance of the facade.
Implementation Method 1
The fire protection insert has a base body that is at least substantially T-shaped and comprises a fire protection material that foams up when exposed to heat
Implementation Method 2
The fire protection insert effectively seals the gap between posts, delaying the disintegration of the construction during a fire by acting as a heat shield
