Drywall Combination Profile for Load-Bearing Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard drywall profiles with 0.6 mm sheet metal thickness are unsuitable for absorbing static loads in house construction, while thicker profiles require complex assembly technologies, increasing construction costs and necessitating specialist labor, limiting acceptance and efficiency in manual assembly.
Innovation Solution
A drywall combination profile with two functional sections: a thick-walled static section for load-bearing and a thin-walled section for easy planking, using varying sheet steel thicknesses and geometries to enhance stability and allow manual assembly, featuring a continuous hole pattern for secure fastening and decoupled paneling for soundproofing and fire protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thicker-walled lightweight steel profiles are used to absorb static loads, then stability and load-bearing capacity are improved, but processing difficulty and assembly complexity increase
Solution Approach 1:
The profile is segmented into two distinct wall thickness zones: a thicker first wall section (1.5-3.0 mm) for load-bearing stability and a thinner second wall section (0.5-1.0 mm) for easy processing. This segmentation allows each zone to be optimized for its specific function, resolving the contradiction between strength and ease of manufacture.
Solution Approach 2:
Different wall thicknesses are applied locally to different functional zones of the profile. The thicker section is positioned where load-bearing capacity is required, while the thinner section is positioned where ease of processing and planking is needed. This local differentiation resolves the contradiction by applying material properties specifically where needed.
2Stability of the object's composition
If thicker-walled profiles are used for static construction, then stability is improved, but assembly complexity and construction costs increase
Solution Approach 1:
The profile combines two wall thickness sections in a single integrated component, eliminating the need for separate assembly of thick-walled structural elements and thin-walled paneling elements. This segmentation within a single profile reduces assembly complexity while maintaining structural stability.
Solution Approach 2:
The invention merges the structural function (thick-walled section) and the paneling function (thin-walled section) into a single integrated profile. This combining of functions reduces the number of components and assembly steps, resolving the contradiction between stability and assembly complexity.
3Ease of operation
If thinner-walled profiles are used for manual planking, then ease of assembly is improved, but load-bearing capacity is reduced
Solution Approach 1:
The profile is divided into functional zones where the thinner second wall section (0.5-1.0 mm) provides ease of planking and manual assembly, while the thicker first wall section (1.5-3.0 mm) provides the necessary load-bearing capacity. This segmentation resolves the contradiction between ease of operation and strength.
Solution Approach 2:
Different wall thicknesses are applied to different functional zones: the thinner section where planking is required for ease of operation, and the thicker section where load-bearing capacity is required. This local quality differentiation resolves the contradiction by optimizing each zone for its specific function.

AI summary
1. The invention relates to a wall construction system comprising drywall construction combination profiled sections, and a method for constructing a wall. 2.1. Standard drywall construction profiled sections using sheet metal that is approximately 0.6 mm thick allow easy manual sheathing of stud walls with building panels, but lightweight sheet metal profiled sections of this type are not suitable for bearing static loads of a house. Thicker walled lightweight steel profiled sections greatly improve stability but require more costly assembly technologies needing specialists, which increases construction costs and therefore stops drywall-constructed housing from becoming more widespread. The new combination profiled sections provide for statically stable construction systems that can nevertheless be worked and sheathed simply and easily. 2.2. The present drywall construction combination profiled section (1) comprises two functional sections. A statically stable section which has splayed flanges (2), and a section comprising a planar thin-walled drywall construction contact surface, acting as a sheathing section (3), which is joined or moulded on. These sections are made with different sheet metal thicknesses in the drywall construction profiled element, or by form-fittingly joining individual lightweight steel profiled sections, or by specific profiling of the flange sections. 2.3. Such a house construction system allows modular assembly of statically stable walls, ceilings and roofs for buildings, using simple manual technology and with minimal costs. Additionally, the construction types are clearly demarcated. 3. Figure 1 depicts a wall cross-section with different drywall construction combination profiled sections.
