Shelf Angle Soffit Assembly for Non-Planar Masonry Veneer Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building structures face challenges in supporting masonry veneers, particularly when walls are non-planar or have interruptions like corners, doors, or windows, as traditional shelf angles and mounting systems struggle to provide stable and efficient support.
Innovation Solution
A masonry veneer support assembly that includes a shelf angle with a web and flange, mounting brackets, and a soffit that extends rearwardly, along with securements and flashing elements, to provide stable support and conceal gaps, suitable for non-planar walls and structural openings.

Engineering Contradiction Analysis
1Ease of operation
If traditional shelf angles are used on non-planar walls or walls with interruptions, then the support system becomes complex and difficult to install, but the structural stability and aesthetic continuity deteriorate
Solution Approach 1:
The shelf angle incorporates adjustable parameters including variable leg lengths and positioning holes that allow adaptation to non-planar wall surfaces and interruptions such as windows and doors. This enables the same standardized component to maintain structural stability while accommodating varying installation conditions without requiring custom fabrication.
Solution Approach 2:
The shelf angle is designed as a segmented component with multiple positioning holes and adjustable legs that can be configured independently. This segmentation allows each portion of the shelf angle to be adjusted separately to fit complex wall geometries, maintaining ease of installation while ensuring structural integrity at each connection point.
2Device complexity
If shelf angles are used to support masonry veneer on walls with interruptions, then the support system becomes complex, but the aesthetic continuity and gap concealment worsen
Solution Approach 1:
The shelf angle serves multiple functions simultaneously: it provides structural support for masonry veneer, accommodates wall interruptions through adjustable positioning, and conceals gaps between the veneer and building structure. This multi-functionality is achieved through integrated design features including the forwardly extending leg that spans interruptions and the rearwardly extending leg that conceals gaps, eliminating the need for separate components and maintaining aesthetic continuity.

AI summary
An assembly supports external masonry veneer. A soffit assembly is provided to close what might otherwise be an open eave lying inboard of the bottom margin of the masonry veneer. The soffit assembly includes a fitting that mounts to the toe of the shelf angle, such that the soffit may be mounted from the shelf angle and run rearwardly toward the supporting wall structure. The soffit assembly may come as a two-part assembly. Alternatively, it may come as a three-part assembly. In either circumstance the soffit assembly may include a drip edge. The soffit assembly includes an external coating. It may be used over a door or window opening between first and second side walls.
