Concrete Form Alignment Device Using Centering Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for aligning columnar concrete forms, such as Sonotube forms, are prone to inaccuracies due to lack of square edges for guide strings, visibility issues for centering, and reliance on external batter boards as reference points, leading to trial and error in setting elevation, location, and plumb level.
Innovation Solution
A device featuring a lid with concentric grooves and post-centering blocks with edge grooves that fit over concrete forms, allowing for accurate alignment and square corner production by using adjustable holes and pegs to center posts and align forms precisely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional trial and error methods are used for aligning concrete forms, then workers can attempt to position forms, but the alignment accuracy deteriorates due to lack of square edges and visibility issues
Solution Approach 1:
The device performs preliminary centering and alignment actions by providing pre-fabricated centering blocks with concentric grooves that fit over the concrete forms. These blocks establish accurate center points and square edges before the actual form alignment process, eliminating the need for trial and error positioning.
Solution Approach 2:
The centering blocks serve as intermediary devices between the workers and the concrete forms. They provide visible reference points (center points and square edges) that mediate the alignment process, making it easier to achieve precise positioning without direct trial and error manipulation of the forms themselves.
2Ease of operation
If external batter boards are used as reference points, then workers have reference points for measuring placement location, but the measurement precision deteriorates due to inaccuracy in establishing external reference points
Solution Approach 1:
The invention extracts the reference function from external batter boards and relocates it directly onto the concrete forms themselves. The centering blocks provide center points and square edges that are intrinsically attached to the forms, eliminating the need for separate external reference structures.
Solution Approach 2:
The centering blocks serve multiple functions simultaneously: they provide center points for positioning, square edges for alignment, and visible references for measurement. This multi-functionality replaces the need for separate external reference systems while improving accuracy.
3Productivity
If workers attempt to center columns over concrete cylinders without visible centering references, then they can proceed with placement, but the centering precision deteriorates due to lack of visibility to the center point
Solution Approach 1:
The centering blocks provide visible visual references (center points and square edges) that make the invisible center of the concrete forms clearly visible. This visual enhancement allows workers to accurately identify and target the center point without trial and error, improving both speed and precision.

AI summary
This invention provides a device and a method for aligning concrete forms. It relates to a device and a method which is used in conjunction with hollow, shaped concrete forms such as Sonotube forms in order to align, square and properly site said forms to produce optimally supported structures. The key advantage of this device and method are to eliminate the trial and error practice in the aligning of wood columns on top of concrete forms, to provide the ability to center or off-center posts accurately as required by the project design, to provide the ability to accurately set the hollow, shaped concrete forms for the proper elevation, for the correct location, and for the correct plumb level, and eliminate the need for batter boards or wooden edge forms which are placed outside of the project dimensions and used as inaccurate reference points for measuring the placement location of the hollow, shaped concrete forms along the edges of a project area.
