Monolithic Air Form Construction for Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods are time-consuming, expensive, and require significant expertise, while they also struggle with effective insulation due to gaps and thermal bridging, and existing monolithic structures either require high capital expenditure or lack adequate insulation.
Innovation Solution
The method involves using pressure-supported air forms and rigid forms to create a mold for curable mixtures like foamed cement, which are inflated to shape and then filled with a moldable material that cures into a monolithic structure, eliminating the need for skilled labor and reducing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional construction methods are used, then structural integrity is achieved, but construction time and cost increase significantly
Solution Approach 1:
The construction process is segmented into distinct phases: foundation preparation, air form erection and inflation, moldable material pouring, and form removal. This segmentation allows parallel execution of tasks and reduces overall construction time while maintaining structural integrity through systematic progression.
Solution Approach 2:
Air forms are erected and inflated before the moldable material is poured, creating a pre-prepared mold that defines the structural geometry. This preliminary action eliminates the need for complex formwork assembly during construction, significantly reducing construction time while ensuring accurate structural dimensions.
2Stability of the object's composition
If conventional construction methods are used, then structural stability is achieved, but insulation performance deteriorates due to gaps and thermal bridging
Solution Approach 1:
The air forms are merged with the moldable material to create a monolithic structure where the insulation and structural components are integrated into a single continuous element. This eliminates gaps and thermal bridges between separate components, simultaneously achieving structural stability and superior insulation performance.
Solution Approach 2:
The moldable material functions as a composite that combines structural and insulating properties within a single monolithic element. This composite approach allows the structure to maintain stability while providing continuous thermal insulation without the need for separate insulation layers or assemblies.
3Loss of energy
If monolithic dome construction is used, then insulation performance is improved, but capital expenditure increases significantly
Solution Approach 1:
Air pressure is used to inflate the forms and potentially to consolidate the moldable material during pouring. This pneumatic approach eliminates the need for heavy mechanical consolidation equipment and complex formwork systems, reducing capital expenditure while maintaining the monolithic structure's insulation performance.
Solution Approach 2:
The air forms utilize flexible membrane structures that can be inflated to create large-scale molds without requiring extensive support frameworks. This reduces material costs and simplifies the construction process, making monolithic construction more cost-effective while preserving the continuous insulation envelope.
4Quantity of substance
If Eco-Shell construction is used, then construction cost is reduced, but insulation value is insufficient
Solution Approach 1:
The thickness and composition of the moldable material are optimized to achieve the desired insulation value. By adjusting these parameters, the structure provides adequate thermal insulation while controlling construction costs, overcoming the insufficient insulation of thin-walled Eco-Shells.
Solution Approach 2:
The moldable material is formulated as a composite with enhanced insulating properties, allowing the structure to achieve superior thermal performance at lower cost compared to traditional monolithic dome construction with conventional materials.
5Loss of energy
If DomeGaia's foamed concrete blocks are used, then insulation value is improved, but construction complexity and skilled labor requirements increase
Solution Approach 1:
The moldable material is prepared and pumped directly to the construction site where it is poured into the air form mold. This preliminary preparation and direct pouring approach eliminates the need for manual block stacking and complex masonry techniques, reducing construction complexity while maintaining the insulating benefits of foamed concrete.
Solution Approach 2:
The manual mechanical process of stacking and sealing individual blocks is replaced with a continuous pouring and consolidation process using pneumatic or hydraulic equipment. This substitution simplifies the construction process, reduces the need for skilled masons, and maintains the insulating performance of foamed concrete.
