Flush Mount Brick Veneer Anchor Cap With Aligned Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flush mount brick veneer anchors suffer from offset force transfer, causing the anchor plate to pivot and weaken the connection between the brick veneer and the stud backup wall, potentially damaging the exterior covering.
Innovation Solution
The design features anchor holes in the anchoring portion above and below the tie wire holding portion, aligning them with the tie wire holding portion to directly transfer compression and extension loads through fasteners to the exterior wall, eliminating offset force transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mounting holes are placed in the anchor plate to the side of the brick tie portion, then the anchor can be installed on the exterior wall, but the compression or extension forces are offset from the anchor points causing the anchor plate to pivot and weaken the connection
Solution Approach 1:
The patent positions the anchor holes asymmetrically relative to the brick tie portion, placing them directly above and below the tie wire holding portion rather than to the side. This asymmetric arrangement aligns the force transfer path with the anchor points, eliminating the offset that causes pivoting and weakening the connection.
Solution Approach 2:
The patent transitions from a lateral arrangement of anchor holes (to the side of the tie portion) to a vertical arrangement (above and below the tie portion). This dimensional change in the placement of anchor holes realigns the force transfer path with the anchor points, preventing offset forces from causing pivot movement.
2Ease of manufacture
If the anchor plate is designed with offset anchor holes, then installation is simplified, but the exterior covering may be damaged due to rotation about the anchor points
Solution Approach 1:
The patent employs an asymmetric placement of anchor holes directly above and below the tie wire holding portion, which changes the force transfer geometry. This asymmetric arrangement ensures that compression and extension forces are transferred directly through the anchor points, eliminating the rotational moment that would otherwise damage the exterior covering.
Solution Approach 2:
By moving the anchor holes from a lateral position to a vertical position relative to the tie portion, the patent creates a direct vertical force transfer path. This dimensional repositioning eliminates the offset that causes rotational movement and potential damage to the exterior covering material.
3Reliability
If the anchor holes are aligned with the tie wire holding portion, then the force transfer is direct and reliable, but the anchor design becomes more specific and less versatile
Solution Approach 1:
The patent divides the anchor into distinct functional segments: an anchoring portion with anchor holes for attachment to the exterior wall, and a tie wire holding portion for securing the brick tie wire. This segmentation allows each portion to be optimized for its specific function while maintaining overall structural integrity and force transfer efficiency.
Solution Approach 2:
The anchor design integrates multiple functions into a single component: it provides wall attachment through the anchoring portion, holds the tie wire through the tie wire holding portion, and transfers forces directly through the aligned anchor holes. This multi-functionality in a unified design maintains versatility while achieving reliable force transfer.

AI summary
A flush mount masonry veneer anchor for mounting on an exterior wall and tying a masonry veneer to the exterior wall, the masonry veneer anchor comprising an anchoring portion with anchor holes to receive a suitable fastener to attach the anchoring portion to an exterior surface of the exterior wall and a tie wire holding portion extending perpendicularly from the anchoring portion, the tie wire holding portion having one end connected to the anchoring portion and having a slot in an opposite end for holding a tie wire for tying the masonry veneer to the exterior wall, the anchor holes being in line with the tie wire holding portion to transfer extrusion and compression loads exerted on the tie wire holding portion directly through fasteners in the anchor holes to the exterior wall without an offset of a plane of the transfer of the forces.
