Modular Wall System With Steel Channels And Concrete Fill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional exterior wall construction is labor-intensive, time-consuming, and costly due to the need for complex wood molding and reinforcement, which results in waste and aesthetic issues, while prefabricated wall panels face challenges with weight, transportation, and potential weaknesses at seams.
Innovation Solution
A wall system using prefabricated panel assemblies connected by roll-formed steel 'U' shaped structural channels and steel plates that can be assembled quickly, remaining in place as integral structural components, eliminating the need for wood molding and providing enhanced strength and a finished appearance without additional surfacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wood molding and reinforcement are used for exterior wall construction, then the concrete can be properly formed and reinforced, but the process becomes labor-intensive, time-consuming, and generates significant waste
Solution Approach 1:
The wall system is divided into modular panel assemblies, each comprising panel members interconnected by steel channels. This segmentation allows panels to be pre-fabricated and assembled quickly on-site, eliminating the labor-intensive traditional molding process while maintaining structural integrity through the modular design and connecting members.
Solution Approach 2:
Panel assemblies are pre-fabricated with integrated steel connecting members and reinforcement elements before arriving at the construction site. This preliminary action eliminates the need for on-site wood molding and reinforcement installation, significantly reducing construction time while ensuring consistent quality and structural reliability.
2Shape
If traditional wood molding is used to form concrete walls, then the concrete can be properly shaped, but the wood must be discarded after use, creating waste and additional costs
Solution Approach 1:
The formwork function and the permanent wall structure are merged into a single integrated system. The steel channels and panel members that form the concrete shape become permanent structural components of the wall, eliminating the need to discard traditional wood molds after use and reducing material waste.
Solution Approach 2:
The panel assembly system performs multiple functions: it serves as the formwork for concrete pouring, provides permanent structural support, and creates the finished wall surface. This self-service capability eliminates the need for separate temporary molding materials that would be discarded after a single use.
3Productivity
If prefabricated wall panels are used, then construction time is reduced, but the panels become heavy and difficult to transport and assemble
Solution Approach 1:
The panel assemblies use composite construction combining lightweight panel members with steel connecting channels. This composite approach provides the necessary structural strength for rapid assembly while keeping the overall weight manageable for transportation and handling, resolving the contradiction between construction speed and panel weight.
4Strength
If traditional concrete walls are made thicker to ensure structural integrity, then strength is improved, but interior space is reduced
Solution Approach 1:
The wall system uses composite construction with steel channels and panel members that provide high strength-to-weight ratio. This allows the walls to achieve required structural strength with reduced thickness compared to traditional concrete walls, thereby preserving interior space while maintaining or improving structural integrity.

AI summary
A wall system including a plurality of panel assemblies, each having a reduced thickness for use in connection with a portion of a building structure. The panel assembly comprises two panel members disposed in interconnecting relation, collectively defining an air gap that is generally filled with a filler material such as concrete. Removable support members are further included and disposed on an outside face of a corresponding panel member. The removable support members may comprise corrugated steel panels that may be held in place along with the panel members by retainers that interconnect the panels and/or removable support members. Wire mesh may be disposed within the air gap. One or more panel assemblies may be interconnected via a connecting assembly. The connecting assembly may comprise a U-shaped channel with one or more apertures.
