Building Block Assembly Thermal Bridge Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional building block assemblies suffer from high heat transmission coefficients due to the use of cementitious mortar, which acts as a thermal bridge, reducing energy conservation and increasing construction costs and time.
Innovation Solution
The development of building blocks with specific geometric designs featuring inner cells and faces with cavities and protrusions, allowing for efficient use of low-thickness adhesive materials like epoxy or polyurethane, which reduces the amount of mortar needed and minimizes thermal bridges, combined with strategic placement of insulating materials within air chambers to lower heat transmission coefficients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cementitious mortar is used to couple building blocks, then the blocks are securely joined, but the thermal transmission coefficient increases significantly
Solution Approach 1:
The invention extracts the harmful thermal bridge function from the coupling material by replacing cementitious mortar with adhesive materials that have low thermal conductivity, thereby removing the energy loss pathway while preserving the structural coupling function
Solution Approach 2:
The invention uses composite adhesive materials combining organic and inorganic components that provide both adequate bonding strength and low thermal conductivity, achieving a balance between mechanical coupling and thermal insulation
2Reliability
If traditional mortar application methods are used, then complete coverage is achieved, but construction time increases
Solution Approach 1:
The invention applies thin film adhesive materials that can be rapidly applied in thin layers, achieving complete coverage and adequate bonding strength without requiring thick applications, thereby significantly reducing construction time while maintaining joint reliability
3Reliability
If thick adhesive layers are used to ensure complete coverage, then bonding reliability improves, but thermal bridges increase
Solution Approach 1:
The invention changes the physical and chemical parameters of the adhesive material, specifically using materials with low viscosity and high open time that enable complete coverage and reliable bonding in thin layers, thereby achieving adequate adhesion without increasing thermal bridge formation
