Masonry Veneer Bracket Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for coupling external building structures, such as decks, to a building frame that pass through masonry veneer often cause damage to the mortar or bricks due to concentrated line or point loads, leading to potential weakening and crumbling of the masonry.
Innovation Solution
A bracket system is designed with a plate-like first portion and a block-shaped second portion that distributes the load over a larger area of the masonry veneer, incorporating a metal connector support co-molded with injection-molded plastic to disperse forces and prevent damage, while being weather-resistant and cost-effective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a connector member is used to couple external building structures to the building frame through masonry veneer, then the building components can be securely connected, but the concentrated line or point loads cause damage to the mortar or bricks
Solution Approach 1:
The bracket serves as an intermediary element between the connector member and the masonry veneer. It distributes the concentrated loads from the connector member across a broader area of the masonry, preventing point or line loads that would cause damage. The bracket body with its outwardly extending portion creates a distributed load path through the masonry veneer while maintaining secure connection between the building components.
2Object-affected harmful factors
If a bracket with extended portion is used to distribute loads over larger masonry area, then masonry damage is prevented, but the device complexity increases
Solution Approach 1:
The bracket is segmented into distinct functional portions: a bracket body for receiving the connector member and a second outwardly extending portion for load distribution. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity. The segmented design enables the bracket to effectively distribute loads without requiring an overly complex monolithic structure.

AI summary
A bracket for a building that includes a first building member, a masonry veneer disposed exteriorly of the first building member, and a second building member disposed exteriorly of the masonry veneer. The bracket includes a bracket body having a first portion for being coupled to the first building member and a second outwardly extending portion having a length sufficient to extend to at least about an exterior surface of the masonry veneer. A connector member extends through the bracket member, and at least partially through each of the first and second building members. A connector support extends through the bracket body and includes a sleeve having a passageway for receiving and supporting the connector member, wherein the bracket body and connector support are configured to distribute a load borne by the connector member on the masonry veneer over an area of the bracket body greater than the area of the connector.
