Veneer Support Bracket with Shear Load Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for supporting external veneer components in building structures, such as face brick or stone, often rely on steel supports that may not effectively distribute shear loads and moment couples, leading to potential instability and misalignment issues.
Innovation Solution
A support assembly comprising a first member with a mounting fitting and a second member with a shear load receiving interface and moment couple reaction interface, where the second member's carrier engages the first member's protrusion, allowing for secure attachment to a load-bearing wall structure and distributing loads efficiently.

Engineering Contradiction Analysis
1Reliability
If traditional steel supports are used to mount external veneer components, then the mounting structure is simple, but the shear loads and moment couples are not effectively distributed, leading to potential instability
Solution Approach 1:
The support assembly is divided into distinct functional components: a mounting fitting for attachment to the load-bearing wall, a seat for supporting the veneer component, and specialized interfaces for shear load and moment couple reactions. This segmentation allows each component to be optimized for its specific function, improving overall reliability while maintaining manageable complexity through modular design.
Solution Approach 2:
Different portions of the support assembly have specialized properties tailored to specific load types. The seat is designed with specific geometric features for supporting veneer components, while the mounting fitting incorporates features optimized for shear load transmission and moment couple resistance. This local optimization ensures effective load distribution without requiring complex overall structure.
2Manufacturing precision
If a simple mounting system is used, then the device complexity is low, but the alignment and structural integrity of veneer components cannot be ensured
Solution Approach 1:
The support assembly incorporates pre-designed geometric features and interfaces that automatically guide and align veneer components during installation. The seat and mounting fitting are configured in advance to ensure proper positioning, eliminating the need for complex alignment procedures or additional adjustment mechanisms during construction.

AI summary
A support assembly for external veneer has a mounting bracket fixedly mounted to a load bearing wall, and a shelf angle. The shelf angle includes a horizontal leg surface upon which to mount veneer members. The mounting bracket may be a channel. The legs of the channel may have seats. The seats have a protruding toe. The back of the shelf angle may admit the toes of the mounting bracket. The toes may be shy of the bottom of the shelf angle. The seat may includes an oversized slot to permit the shelf angle web to be rotated angularly during assembly. The legs of the bracket may be long, to permit the seat to hang down well below the mounting. The legs of the bracket may be perforated to reduce heart transfer.
