Foamable Adhesive Bonding for Masonry Veneer Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing masonry veneers on existing walls are complex and costly due to the need for open spaces, weep holes, and mechanical fasteners, which also compromise insulation, waterproofing, and aesthetic properties.
Innovation Solution
The method involves constructing a masonry wall adjacent to an existing wall with a cavity filled with a foamable, adhesive material that adheres to both walls, eliminating the need for mechanical fasteners and weep holes, while using clips for temporary securing and a brush device to remove excess mortar, creating a strong, insulated, and waterproof bond.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical fasteners and open space with weep holes are used to construct masonry veneer, then structural connection and moisture drainage are achieved, but device complexity and total cost increase
Solution Approach 1:
The patent combines multiple functions into a single material: the adhesive foam serves as both the structural bonding agent and the moisture drainage medium. The foam's cellular structure provides capillary channels for water drainage while its adhesive properties provide structural connection, eliminating the need for separate mechanical fasteners and weep hole systems.
Solution Approach 2:
The adhesive foam material performs multiple functions simultaneously: it bonds the masonry veneer to the substrate, provides insulation, allows moisture drainage through its cellular structure, and creates a vapor barrier. This multi-functionality replaces the traditional separate systems of mechanical fasteners, drainage cavities, and insulation layers.
2Reliability
If mechanical fasteners and open space are used to construct masonry veneer, then structural connection and moisture drainage are achieved, but total cost increases
Solution Approach 1:
The patent extracts and eliminates unnecessary components from the traditional masonry veneer system. By removing mechanical fasteners, open drainage cavities, and separate insulation layers, the design reduces material costs, labor costs for installation, and maintenance costs while maintaining all essential functions through the adhesive foam alone.
3Object-affected harmful factors
If traditional masonry veneer construction with open space is used, then moisture drainage is achieved, but insulation and waterproofing properties are compromised
Solution Approach 1:
The adhesive foam provides different properties at different scales: at the macro level, it creates a continuous waterproof barrier and insulation layer; at the micro level, its cellular structure provides capillary channels for moisture drainage. This local differentiation of properties allows simultaneous achievement of waterproofing, insulation, and drainage functions.
