Adjustable Masonry Anchor With Movable Bushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems for securing masonry facades to interior walls face difficulties due to misalignment with mortar bed joints, making the application of wall anchors challenging.
Innovation Solution
An adjustable anchor system with an engagement portion configured for disposition in the mortar bed joint and an attachment portion with an elongate slot and movable bushing, allowing for vertical and horizontal adjustment to ensure proper alignment and secure attachment to the inner wythe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fixed anchoring systems are used, then the structure is simple, but alignment with mortar bed joints becomes difficult
Solution Approach 1:
The anchor incorporates a movable bushing within an elongate slot that allows the engagement portion to move relative to the attachment portion. This dynamic adjustment mechanism enables the engagement portion to align with the mortar bed joint while the attachment portion remains secured to the inner wythe, resolving the alignment difficulty without requiring complex pre-positioning.
Solution Approach 2:
The anchor is divided into distinct functional portions: an attachment portion for securing to the inner wythe, an engagement portion for positioning in the mortar bed joint, and a movable bushing connecting them. This segmentation allows each portion to be optimized independently and facilitates adjustment during installation to achieve proper alignment.
2Manufacturing precision
If adjustable components are added to achieve proper alignment, then alignment accuracy improves, but device complexity increases
Solution Approach 1:
The movable bushing within the elongate slot provides a simple yet effective adjustment mechanism that enables precise alignment of the engagement portion with the mortar bed joint. The bushing can slide along the slot to accommodate variations in positioning, achieving high alignment precision without requiring complex adjustment devices.
Solution Approach 2:
The bushing acts as an intermediary element between the attachment portion and the engagement portion. It provides the necessary adjustment capability while maintaining a relatively simple overall structure, bridging the gap between the fixed attachment point and the movable engagement point.

AI summary
An anchor for use in joining inner and outer wythes of the wall. The outer wythe is formed from successive courses of masonry units with a mortar-filled bed joint between each two adjacent courses. The anchor comprises an engagement portion configured for disposition in the bed joint and an attachment portion coupled to the engagement portion. The attachment portion is configured to be secured to the inner wythe. The attachment portion defines an elongate slot. A bushing defines an opening sized and shaped to receive a fastener to attach the attachment portion to the inner wythe. The bushing is movably attached to the attachment portion to permit movement of the bushing and attachment portion relative to one another. This permits the engagement portion to move relative to the outer wythe to position the engagement portion in the bed joint when the fastener secures the attachment portion to the inner wythe.
