Fire-Resistant Panel Composite for 250 kg/m² Load Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire-resistant panels do not meet the required carrying capacity standards of R30 and R60 as defined by EN 13501-2:2016, leading to potential collapse under load during a fire.
Innovation Solution
A fire-resistant panel system comprising aluminium plates, mineral wool fill, stainless steel frame, and EPDM foam sealing, with a U-shaped cross-section frame and corner joints, ensuring structural integrity and fire resistance, and installation using aluminium holders and stainless steel side carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fire-resistant panels are used, then fire resistance is provided, but carrying capacity under fire load is insufficient
Solution Approach 1:
The panel combines aluminium plates with mineral wool fill and stainless steel frame to create a composite structure that simultaneously achieves high carrying capacity (250 kg/m²) and fire resistance (R60 class). The mineral wool provides fire insulation while the metal components provide structural strength.
Solution Approach 2:
The panel uses different materials with specific properties in different locations: aluminium plates for structural integrity, mineral wool for fire insulation, and stainless steel frame for reinforcement. This local optimization ensures both strength and fire resistance are achieved where needed.
2Strength
If panel thickness is increased to improve carrying capacity, then load bearing improves, but installation complexity increases
Solution Approach 1:
The panel is divided into modular components (aluminium plates, mineral wool fill, stainless steel frame) that can be independently manufactured and then assembled. This segmentation allows for simplified installation despite the substantial thickness required for carrying capacity.
Solution Approach 2:
The panel components are pre-assembled into a complete fire-resistant unit before installation. The aluminium plates, mineral wool, and frame are combined in advance, reducing on-site assembly complexity while maintaining the required thickness for load bearing.
