Prefabricated Wall with Spacer and Cement Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for constructing building walls with thermal inertia, involving load-bearing walls and exterior insulation, are costly and labor-intensive, especially for smaller structures, due to manual processes and the need for formwork in existing techniques.
Innovation Solution
A method using thermally insulating plates and plaster plates with a spacer and a cement-water mixture poured between them, which hardens to form a load-bearing wall, eliminating the need for formwork and allowing for rapid setting concrete, thus reducing construction time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual mounting of concrete blocks is used, then wall construction can be performed with simple tools, but construction time and labor cost increase significantly
Solution Approach 1:
The wall is divided into modular concrete blocks that can be pre-fabricated and then assembled. Each block is a self-contained unit with integrated insulation and facing layers, allowing for rapid assembly without manual mortar application or formwork between blocks.
Solution Approach 2:
The concrete blocks are pre-fabricated with all necessary layers (insulation, facing, structural concrete) already integrated before arrival at the construction site. This preliminary preparation eliminates the need for complex on-site assembly operations and formwork.
2Strength
If formwork is used for concrete wall production, then structural integrity can be ensured, but device complexity and manual labor increase
Solution Approach 1:
The formwork system is completely removed from the construction process. Instead of using formwork to shape concrete, pre-fabricated concrete blocks with integrated reinforcement are used, eliminating the need for formwork assembly, dismantling, and cleaning operations.
Solution Approach 2:
The concrete blocks are self-contained units with reinforcement and insulation already integrated during manufacturing. The blocks themselves serve as both the structural element and the insulation layer, eliminating the need for separate formwork and insulation installation steps.
3Object-affected harmful factors
If exterior insulation is installed after load-bearing wall completion, then thermal insulation can be added, but construction time and labor cost increase
Solution Approach 1:
The structural concrete wall, exterior insulation layer, and interior facing are merged into a single integrated pre-fabricated block. This consolidation allows all layers to be installed simultaneously as one unit, eliminating the sequential construction steps required when installing insulation separately after wall completion.
Solution Approach 2:
The concrete block serves multiple functions simultaneously: it provides structural load-bearing capacity, thermal insulation, and interior facing. This multi-functionality eliminates the need for separate construction steps for each function, reducing overall construction time and labor requirements.
