Adjustable Brick Support Bracket with Z-Axis Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current masonry support systems for brickwork facades lack adequate adjustment mechanisms to accommodate site variances in cavity widths and loading conditions, leading to potential sagging and weak spots due to insufficient support at the midpoint between brackets.
Innovation Solution
A masonry support system with integrated Z-axis adjustment using slots and a lock-washer mechanism for forward and backward adjustment, along with a serrated toothed area for increased contact and shear load capacity, and an upstanding lip for improved flexural rigidity and mortar retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed-length brackets are used to match theoretical cavity width, then manufacturing precision is improved, but adaptability deteriorates because brackets cannot accommodate site variances in cavity width
Solution Approach 1:
The bracket system transitions from fixed-length to adjustable-length configuration through the integration of shims between the bracket and support structure. This allows the bracket to dynamically adapt to varying cavity widths while maintaining precise manufacturing tolerances for the bracket components themselves.
Solution Approach 2:
Shims are introduced as intermediary elements between the bracket and the support structure. These shims compensate for variations in cavity width by being inserted to the appropriate thickness, allowing the bracket to maintain its precise manufactured dimensions while adapting to different site conditions.
2Adaptability or versatility
If shims or packing plates are used to offset the bracket, then adaptability is improved, but device complexity increases and adjustment is limited to bolt diameter
Solution Approach 1:
The shim serves multiple functions: it compensates for cavity width variations, provides a bearing surface for the bracket, and facilitates adjustment during installation. This multi-functionality reduces the need for additional specialized components and simplifies the overall system.
3Device complexity
If folded angle pieces are used without intermediate support, then device complexity is reduced, but reliability deteriorates due to insufficient support at the toe midpoint causing sagging
Solution Approach 1:
The horizontal support section incorporates a toe section with increased thickness or reinforcement at the midpoint between brackets. This local quality enhancement provides additional support where the masonry panel experiences maximum bending moment, preventing sagging while maintaining overall structural simplicity.
4Manufacturing precision
If precise bracket sizing is provided for theoretical cavity width, then manufacturing precision is improved, but ease of operation deteriorates because no negative adjustment is possible if wall cavity is narrower
Solution Approach 1:
The system allows dynamic adjustment in both directions (increasing and decreasing the effective bracket length) by selectively positioning shims. This enables installers to accommodate narrower cavities by reducing the number or thickness of shims, providing operational flexibility while maintaining precise manufacturing tolerances.
