Keywell Form Retention Assembly for Cement Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cement form support devices fail to securely retain keyway forms in place during cement curing, as they often float upwardly or move laterally within the cement, leading to instability and potential defects in the formed structure.
Innovation Solution
A vertical post with planar sides, mounting holes, a movable arm, and an anchor plate system that includes a sleeve, arm, and leg, allowing for secure attachment to a cement form and a panel to stabilize the keyway form, preventing movement and ensuring proper curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a form is forced downwardly in liquid cement, then the keyway form can be positioned, but the form floats upwardly or moves laterally within the cement
Solution Approach 1:
The support device is divided into multiple functional segments: a post for vertical support, an arm for lateral positioning, and an anchor plate for securing to the form. This segmentation allows each component to address specific movement issues independently, preventing both upward floating and lateral movement.
Solution Approach 2:
The arm acts as an intermediary mechanism between the post and the anchor plate, providing a movable connection that allows the anchor plate to be positioned precisely on the form while maintaining stability. The arm's perpendicular orientation to the post creates a stable triangular support structure.
2Ease of operation
If existing support devices are used, then forms can be supported, but they fail to securely retain keyway forms in place
Solution Approach 1:
The arm is designed to be movable relative to the post, allowing dynamic adjustment during installation to accommodate different form positions. Once positioned, the arm provides stable support, combining ease of installation with reliable retention during curing.
Solution Approach 2:
The device transitions from simple vertical support to three-dimensional positioning by adding the arm that extends perpendicular to the post. This dimensional addition allows the anchor plate to engage with the form in multiple directions, significantly improving retention reliability.
3Device complexity
If a simple post structure is used, then the device is simple, but it cannot prevent lateral or upward movement
Solution Approach 1:
The device is divided into multiple functional segments: a post for vertical support, an arm for lateral positioning, and an anchor plate for securing to the form. This segmentation allows each component to address specific movement issues independently, preventing both upward floating and lateral movement.
Solution Approach 2:
The arm is designed to be movable relative to the post, allowing dynamic adjustment during installation to accommodate different form positions. Once positioned, the arm provides stable support, combining ease of installation with reliable retention during curing.

AI summary
A keywell form retention assembly includes post that having a bottom end and a top end. The post has a front side and a back side. A plurality of mounting holes extends through the front and back sides. The mounting holes receive fasteners to mount the post to a cement form. A sleeve is attached to the top end of the post. An arm has a first end and a second end. The arm extends through the sleeve and is movable forward or rearward through the sleeve. A leg is attached to and extends downwardly from the arm adjacent to the first end. An anchor plate is attached to the leg. The anchor plate has a mounting aperture extending therethrough to receive a coupler to engage a panel. The anchor plate retains the panel such that that panel abuts and stabilizes a keyway form.
