Self-Supporting Brick Chimney Guide for Plumb Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing masonry guides for brick chimneys and columns require attachment to adjacent framing structures, which is not feasible when constructing above a sloped roof, and they do not physically hold all four corners of the chimney in alignment, leading to increased labor costs and construction time.
Innovation Solution
A self-supporting brick chimney guide comprising four angle upright members connected by horizontal support bars, which can be attached to the previously constructed segment of the chimney, physically constraining all four corners and ensuring alignment without the need for external framing, using adjustable components like thumb screws and jacking screws for stability and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional masonry guides are used that attach to adjacent framing structures, then the guides can provide alignment support, but they cannot be used when constructing above a sloped roof where no adjacent framing is available
Solution Approach 1:
The guide system attaches to itself through the previously constructed chimney section rather than requiring external framing structures. The angle upright members connect to the chimney corners, making the system self-sufficient and applicable to any chimney construction scenario regardless of adjacent framing availability.
Solution Approach 2:
The guide is divided into four independent angle upright members that can be separately attached to each corner of the chimney. This segmentation allows the system to adapt to various chimney sizes and configurations while maintaining independence from external framing structures.
2Productivity
If traditional masonry guides are used that only indicate alignment positions, then the device structure is simple, but they do not physically hold the bricks in position requiring more labor and time
Solution Approach 1:
The guide combines multiple functions into a single system: alignment indication through visual references and physical constraint through the angle upright members that hold bricks in position. This merging eliminates the need for separate alignment tools and manual positioning, significantly improving construction speed.
Solution Approach 2:
The angle upright members act as intermediaries between the chimney structure and the bricks being laid. They provide both the alignment reference and the physical constraint force needed to hold bricks in the correct position, mediating the alignment process efficiently.
3Manufacturing precision
If a guide system is used that holds all four corners plumb, then alignment precision is improved, but the device becomes more complex requiring multiple support components
Solution Approach 1:
The system uses four angle upright members attached to the four corners of the chimney, creating a symmetric arrangement that provides balanced support. The asymmetry principle is applied in the adjustable positioning mechanisms that allow each corner to be independently aligned, ensuring precise alignment while maintaining overall system symmetry.
4Adaptability or versatility
If the guide is designed to be adjustable to fit various chimney sizes, then versatility is improved, but the device complexity increases requiring adjustable components
Solution Approach 1:
The guide system incorporates dynamic, adjustable components that allow the angle upright members to be positioned at various heights and angles. This adjustability enables the same basic structure to accommodate different chimney sizes and configurations, providing versatility without requiring multiple specialized guides for each size.

AI summary
The brick chimney guide is an apparatus for holding successive brick courses in proper alignment during the construction of brick chimneys or columns. The apparatus is comprised of four angle upright members mutually connected by eight horizontal bars. The end of each horizontal bar is held frictionally by corner brackets at the top and bottom of each angle upright member. The guide is attached to a chimney by jacking screws on the bottom of each of the four angle upright members. The screws hold the guide in place by friction and help align the guide in a plumb and square manner. The angle upright members physically maintain each of the four corners of the brick structure in vertical alignment throughout the construction process.
