Continuous Insulation Layer in Truss Building Framework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods face challenges in achieving high thermal insulation, are labor-intensive and costly, and make it difficult to inspect the structural integrity of buildings during construction, leading to potential non-compliance with regulations.
Innovation Solution
A method involving the erection of truss elements to form a framework with an enclosed void between inner and outer covering layers, which is filled with insulating material to create a continuous and seamless insulation layer around the building, reducing the need for deep foundations and allowing for easier inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional insulation methods are used (inserting material into cavity between inner and outer walls), then thermal insulation can be provided, but gaps are left around eaves and beneath floor space allowing thermal bridging and air flow
Solution Approach 1:
The patent transitions from 2D wall cavity insulation to 3D continuous envelope insulation by creating an outer covering layer that extends continuously around the entire building perimeter including walls, floor, and roof, eliminating gaps in all dimensions
Solution Approach 2:
The outer covering layer is designed to extend substantially continuously around the entire building envelope without interruption, ensuring unbroken thermal insulation continuity from walls through floor to roof, preventing thermal bridging and air leakage paths
2Strength
If solid walls are constructed using conventional methods, then structural strength is achieved, but inspection of building components during construction becomes very difficult
Solution Approach 1:
The building envelope is segmented into distinct inner and outer covering layers with a continuous void between them, allowing the structural framework to remain exposed and inspectable while the outer layer provides the insulation function
Solution Approach 2:
The continuous void between inner and outer covering layers serves as an intermediary space that allows inspection of structural components while still providing the required thermal insulation function when filled with insulating material
3Strength
If deep trenches and concrete foundations are laid to support brick or stone walls, then sufficient structural support is provided, but construction time and cost increase substantially
Solution Approach 1:
The patent changes the material parameter from heavy brick/stone walls to lightweight truss framework, which fundamentally alters the foundation requirements from deep concrete trenches to simpler, faster-to-install foundation systems
Solution Approach 2:
The truss framework combines wood or metal members with bracing elements to create a composite structural system that achieves required strength with much less weight than solid masonry, enabling reduced foundation complexity

Function Achieved in This Case
This method achieves high thermal insulation with reduced construction costs and labor, enabling rapid construction, improved safety, and compliance with building standards, while providing resistance to external forces and flood protection.
Implementation Method 1
injecting an insulating material into said void to form an insulating layer between the inner and outer layers that extends substantially continuously through the floor structure, the roof structure and the opposed wall structures

AI summary
A method of constructing a building including erecting a plurality of truss elements to form a framework including one or more walls, a roof structure and a floor structure. Each truss element includes at least two joists and a plurality of braces that maintain the joists in a parallel arrangement, the truss elements being arranged in the framework to provide an inner joist and an outer joist. An inner covering layer and an outer covering layer are attached to the framework, thereby forming an enclosed void between the inner and outer covering layers that extends substantially continuously around the framework. An insulating material is injected into the void to form a substantially continuous insulating layer between the inner and outer layers.
