Foam Cement Composite House for Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container-type houses suffer from poor heat preservation, insulation, and sound insulation due to high thermal conductivity of steel, and wood-made houses lack fire resistance and adequate insulation.
Innovation Solution
A container-type combined house constructed using prefabricated foam cement composite boards with integrated facilities and a construction method that includes connecting steel frames, reinforcement trusses, inorganic foam cement core materials, and cement mortar layers, along with pre-installed water and electrical fittings, providing enhanced insulation, fireproofing, and soundproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel is used as the main material for container-type houses, then structural strength and durability are improved, but heat preservation and insulation performance deteriorate due to high thermal conductivity
Solution Approach 1:
The patent applies composite materials by combining steel frames with foam cement composite boards that contain inorganic foam cement core materials. This composite structure maintains the structural strength of steel while the foam cement core provides thermal insulation properties, resolving the contradiction between strength and heat preservation.
Solution Approach 2:
The patent implements local quality by using different materials for different functional requirements: steel frames for structural strength in load-bearing elements, and foam cement composite boards for thermal insulation in wall and panel structures. This localized material assignment allows simultaneous achievement of strength and insulation.
2Ease of manufacture
If conventional container-type houses are constructed using steel or wood, then construction simplicity is maintained, but fire resistance and sound insulation performance deteriorate
Solution Approach 1:
The foam cement composite boards combine inorganic foam cement (fire-resistant) with steel frames and cement mortar layers, creating a material that simultaneously provides fire resistance, sound insulation, and construction simplicity. The composite structure integrates multiple protective functions within a single building component.
Solution Approach 2:
The patent changes the material parameters by using inorganic foam cement with specific density and porosity characteristics that provide both fire resistance and sound insulation while maintaining ease of construction. The foam cement's porous structure enhances acoustic insulation without compromising fire safety.
3Productivity
If prefabricated facilities are integrated into foam cement composite boards, then construction time and energy consumption are reduced, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-installing water supply pipe fittings, water drainage pipe fittings, electric devices, door holes, and window holes during the foam cement composite board manufacturing process. This advance preparation eliminates the need for on-site installation work, significantly reducing construction time while the modular board design keeps manufacturing complexity manageable.
Solution Approach 2:
The patent merges multiple construction functions into a single integrated component - the foam cement composite board. By combining structural support, insulation, and pre-installed utilities into one element, the patent reduces the number of separate installation steps, thereby reducing construction time without proportionally increasing manufacturing complexity.
