Metal-Clad Drywall Panel Structure for Fire and Moisture Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dry interior construction methods using gypsum plasterboard panels are time-consuming, generate waste, require significant installation space, and lack adequate fire resistance and acoustic insulation, while being susceptible to moisture penetration.
Innovation Solution
A panel system with a gypsum fiber core covered by moisture-resistant metallic panels, featuring pre-bonded intermediate fillings and precise dimensions, allowing for quick installation by sliding into pre-installed profiles without fasteners, and incorporating seals to prevent moisture ingress and enhance fire and sound insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gypsum plasterboard panels are used for dry interior construction, then the installation process is simple and quick, but the fire resistance and acoustic insulation are insufficient
Solution Approach 1:
The patent applies composite materials by combining gypsum fiberboard core with metallic cover panels (steel or aluminum) to create a sandwich-structured panel. This composite structure provides both fire resistance from the metal layers and acoustic insulation from the gypsum core, while maintaining a relatively simple overall panel design that can be installed as a single unit.
2Productivity
If standard drywall panels are cut and installed on-site, then the installation is straightforward, but construction time is extended and waste is generated
Solution Approach 1:
The patent implements preliminary action by pre-assembling the intermediate filling between the cover panels and the core board at the factory before the panel leaves the production line. This pre-assembly eliminates on-site cutting and installation steps, significantly reducing construction time and preventing generation of cut-off waste pieces.
Solution Approach 2:
The patent merges multiple components (cover panels, core board, intermediate filling) into a single pre-assembled panel unit. This integration allows the entire wall assembly to be installed as one piece rather than requiring separate installation of multiple components, thereby speeding up construction and reducing waste.
3Reliability
If gypsum plasterboard is used without additional fire-resistant layers, then the installation space is minimized, but fire-retardant properties are insufficient
Solution Approach 1:
The patent uses composite materials with thin metallic cover panels (steel or aluminum) bonded to the gypsum fiberboard core. These metal layers provide fire resistance while occupying minimal space, achieving fire-retardant properties without significantly increasing the panel thickness or installation space requirements.
4Ease of operation
If conventional plasterboard panels are used, then the material is inexpensive and easy to work with, but acoustic insulation is weak and space efficiency is poor
Solution Approach 1:
The patent employs composite materials combining gypsum fiberboard with metallic cover panels in a sandwich structure. This composite design maintains ease of installation similar to conventional drywall while significantly improving acoustic insulation through the layered construction that dampens sound transmission.
5Reliability
If panels are designed for wet room installation with moisture-resistant filling and sealing, then moisture protection is enhanced, but the panel structure becomes more complex
Solution Approach 1:
The patent uses moisture-resistant materials throughout the panel construction, including moisture-resistant gypsum fiberboard core, metallic cover panels that are inherently moisture-resistant, and moisture-resistant intermediate filling. This comprehensive use of composite moisture-resistant materials provides superior moisture protection without requiring additional sealing layers or complex protective structures.

AI summary
The invention relates to a panel (1) for the production of non-load-bearing walls for dry interior construction using a panel core (2) suitable for dry construction, wherein the panel core (2) is bonded on both sides to at least one moisture-resistant cover panel (3, 4) and has a groove (6) on at least one side extending between the cover panels (3, 4) and designed to form the underside (5) when installed, which is designed to receive a web (7) of a floor profile (8). At least one of the cover panels (3, 4), preferably both cover panels (3, 4), are made of metal, preferably aluminum, or an aluminum alloy, in particular aluminum-manganese alloys.
